According to the initial plan, after pacifying the Sky Battle Zone and the Deep Sea Forest Battle Zone, they were supposed to head directly to the most intense and dangerous Sea Ruins Battle Zone. Once the Sea Ruins Battle Zone was pacified, all three dangerous zones would be resolved.

However, things took a turn for the worse when an abyssal rift in the Black Reef Battle Zone expanded into a large-scale rift during this period.

They couldn’t leave it unattended.

Thus, Saga and Yekaterina adjusted their plan. After resting, they immediately set off for the Black Reef Battle Zone, where the Golden Dragon currently resided.

During this time, the news of Saga and Yekaterina, the legendary dragons, pacifying two battle zones spread like a hurricane across the Golden Sea. The dragons collectively referred to them as the Light of the Deep Sea.

The “Light of the Deep Sea” hadn’t visited all the battle zones, but their consecutive victories brought an undeniable boost in morale.

Dragons in other medium and small battle zones, seeing the dawn of victory, became invigorated, their fighting spirit soared, and morale increased significantly. For a time, they even managed to drive back the abyssal prisoners, and the war showed signs of improvement across the board.

“The Light of the Deep Sea. I’d prefer a unique title rather than being grouped with you, but I can reluctantly accept it,” said Yekaterina, lifting her head.

“Oh? What other title do you want? Dragon Empress is already quite impressive,” Saga, resting in the same palace, replied.

“The more titles, the better. I don’t mind having many,” Yekaterina responded.

Dragons have a fondness for various titles. In dragon culture, the more titles one has when introducing oneself, the more prestigious it is. Of course, these titles must be recognized by the world, not self-proclaimed.

Saga thought for a moment. He already had quite a few titles, more than many ancient dragons.

Dragon City Champion, Golden Heart, King of the Near Seas, Golden Winged Fiend, Emperor Dragon of Armageddon, Death Wing, and one he wasn’t too fond of mentioning, Flower of the World.

With so many titles, Saga could mix and match them as he liked during introductions, or mention them all.

“Have you gained any other interesting titles during your adventures?” Yekaterina asked, a smile playing on her lips.

Saga glanced at Yekaterina and calmly said, “Outside of Deep Sea Dragon City, they also call me Death Wing, Golden Winged Fiend, King of the Near Seas, and Emperor Dragon.”

Yekaterina’s eyes widened.

“You’re lying.”

Saga’s titles included king, emperor, death, and fiend—words that are highly prestigious in dragon culture. Having one such title was impressive enough, but he claimed to have four, making it hard for Yekaterina to believe.

“Leave Deep Sea Dragon City and ask around in the Yarl Continent. You’ll see if I’m lying,” Saga said, his golden dragon tail swaying happily at Yekaterina’s disbelief.

“Hmph, don’t get too cocky. Once the war is over and I leave Deep Sea Dragon City, I’ll earn more and mightier titles than you,” Yekaterina retorted, changing the subject as she didn’t want to continue on this topic. She asked, “Saga, what is the name of the skill you use in battle that can annihilate all beings below legendary level in one go? I feel it’s somewhat similar to my abilities. Maybe I can learn it too.”

Saga’s eyes flickered, thinking it might be good to exchange insights on their abilities with Yekaterina.

Yekaterina’s abilities were essentially nuclear energy, somewhat related to strong and weak nuclear forces.

The destructive energy released by Saga’s neutron annihilation could also be considered nuclear energy.

That’s why Yekaterina felt a sense of familiarity.

“I call it Neutron Annihilation,” Saga said, choosing his words carefully. “Its fundamental principle is the decay of microscopic particles.”

To ensure Yekaterina understood, Saga explained the microscopic realm and his knowledge of atoms and molecules in detail.

“Microscopic particle decay. According to you, your Neutron Annihilation should more accurately be called nuclear decay or atomic decay,” Yekaterina mused.

Though she usually seemed less intelligent, it was only because she had a brain but didn’t like to use it. When it came to knowledge that could enhance her power, Yekaterina showed remarkable intelligence and comprehension.

She looked down at herself, thought for a moment, and then said to Saga, “Most of what makes up my body is something called ‘plutonium’ in our heritage records. It should be a type of heavy microscopic particle.”

“My energy source is the fission of plutonium particles. When they split, they generate vast amounts of energy, so much that I need to control it to avoid injuring myself.”

Nuclear fission.

Hearing Yekaterina’s explanation, Saga’s eyes flickered, and he said, “Yekaterina, different microscopic particles have different masses.”

“Plutonium is what you call plutonium particles, a type of heavy microscopic particle. These heavy particles can split into smaller particles, releasing vast amounts of nuclear energy.”

Saga paused before continuing, “But have you ever thought that if large particles can release energy through fission, what about small particles through fusion?”

Yekaterina was slightly taken aback.

“Small particle fusion? What do you mean?”

She had a vague sense of understanding but couldn’t grasp it clearly. At the same time, she felt that what Saga was about to say would be very important to her.

“Heavy nuclear fission involves bombarding large particles with neutrons to split them into smaller particles.”

“Conversely, there is also—light nuclear fusion, where small particles fuse into larger particles.”

“Both methods generate vast amounts of energy, with the latter being many times stronger.”

Saga explained simply.

“Nuclear fission, nuclear fusion,” Yekaterina muttered, her eyes gradually brightening as if she had an epiphany.

After taking a deep breath, Yekaterina calmed down and tilted her head, saying somewhat troubled, “I know how to perform nuclear fission. Initially, it was instinctual, but now that I understand the principle, I can control it skillfully. But nuclear fusion? Theoretically possible, but under what conditions can it be achieved?”

“High temperature and high pressure,” the golden dragon said quietly.

“You can try nuclear fusion in a high-temperature, high-pressure environment.”

High temperature and high pressure? Yekaterina suddenly understood, then looked at her dragon brother in astonishment and couldn’t help but say, “We have the same heritage knowledge, but it feels like you know more than I do.”

“Because I’m naturally smart, my foolish sister,” Saga replied casually.

This time, when Saga called her foolish, Yekaterina uncharacteristically didn’t retort. Instead, she was silent for a moment before sincerely thanking Saga, “Saga, the knowledge you’ve shared is crucial to me. Thank you.”

Now it was Saga’s turn to be surprised.

“Is there something wrong with my ears?”

“The never-yielding Yekaterina actually knows how to say thank you.”

“Is the Yekaterina in front of me a shapeshifter in disguise?”

Saga said in an exaggerated tone.

Yekaterina, embarrassed and angry, said, “Ungrateful! I want to take back what I just said.”

“How will you take it back? Can you turn back time?”

“I’ll beat you until you forget.”

“I just taught you such important knowledge, and you want to beat me? Did a gnoll eat your conscience?”

After a friendly conversation, both calmed down. Yekaterina thought for a moment and said, “Saga, since you can use Neutron Annihilation, it means you also have the power to influence the microscopic world. Let me teach you how to use heavy nuclear fission.”

Saga’s eyes flickered, and he nodded.

He had the theoretical knowledge but had never actually practiced it.

From what Saga understood, he could now use a bit of weak nuclear force for nuclear decay and fusion. Neutron Annihilation was essentially nuclear decay.

But he had never used strong nuclear force, which was related to nuclear fission.

Understanding nuclear fission in depth would help Saga master strong nuclear force.

“Perhaps, I can open the door to strong nuclear force this way.”

“As for nuclear fusion related to weak nuclear force, hehe, once Yekaterina figures it out, I’ll learn directly from her.”

Transitioning from theory to practice requires a challenging exploration process. Saga had tried using weak nuclear force for fusion before, but starting is always difficult. Naturally, he failed repeatedly and had no clear direction. Yekaterina’s abilities made her better suited to using nuclear energy and mastering nuclear reactions.

The applications of weak and strong nuclear forces are not limited to fusion and fission.

Each fundamental force involves a vast realm.

However, understanding weak and strong nuclear forces more deeply through this process was a good choice for Saga.

“Look, this is a plutonium particle, and this is a neutron,” Yekaterina said, extending her dragon claw and gently transforming it.

Flames ignited in the deep sea, forming variously sized spheres in front of her, simulating heavy nuclear particles and neutrons.

“Bombard the plutonium particle with the neutron.”

As she spoke, Yekaterina swung her dragon claw, and the neutron fireball fiercely struck the plutonium particle.

“The plutonium particle will split, undergoing a chain reaction to become smaller particles, releasing vast amounts of energy.”

The plutonium fireball struck by the neutron fireball trembled, splitting into two smaller particle fireballs, surrounded by blazing flames representing energy.

Without stopping, the two particle fireballs continued to split, becoming four and releasing more energy.

Then four became eight, and eight became sixteen. In no time, the initial two fireballs had turned into a sea of fire, causing the surrounding seawater to sizzle and evaporate.

Saga watched quietly.

The principle of nuclear fission was not difficult to understand, and Yekaterina’s simulation was simple and effective.

“You should understand the principle by now. Next, pay close attention and focus. I’ll demonstrate real nuclear fission for you.”

Yekaterina said seriously.

She led Saga out of the palace to an underwater mountain range outside Deep Sea Dragon City.

Yekaterina raised a hooked claw, and a tiny golden particle the size of a speck of dust slowly floated up, rising higher and higher.

Gathering psychic energy in his eyes, Saga looked up, his vision zooming in on the golden particle, delving into it, and witnessing the nuclear reaction within.

Before long.

Boom!

A mushroom cloud of blazing fire erupted in the deep sea, with blinding light and high-pressure shockwaves surging forth, creating countless dangerous currents.

This was just the beginning.

One mushroom cloud after another exploded, causing the sea to tremble continuously.

Before long, Saga had memorized the specific process of nuclear fission, though he still lacked practical experience. This required extensive practice and couldn’t be rushed. Saga wasn’t in a hurry to master nuclear fission now; he was more interested in understanding the strong nuclear force reactions during nuclear fission to feel and attempt to use the strong nuclear force. For Saga, the process of nuclear fission was more important than the result.

“How do you feel? Do you want to continue?” Yekaterina paused and asked.

“It’s enough.”

“Let’s go back and rest well. We still have two battle zones to pacify.”

Saga nodded lightly and returned to the palace in Deep Sea Dragon City with Yekaterina to rest.

One could absorb omnipresent power essence, and the other could generate vast amounts of nuclear energy. Although the previous intense battles had consumed a lot, they were recovering at an astonishing speed.

After some time, while the dragons who had fought in the Sky Battle Zone were still recovering, Saga had already adjusted himself back to peak condition, full of energy and spirit.

As he grew stronger, Saga suspected he would become like a perpetual motion machine, never feeling tired.

On the other hand, Yekaterina had also mostly recovered.

But just as they were about to set off for the Black Reef Battle Zone, a golden light appeared in the water, and a projection of the Golden Dragonfather appeared before Saga and Yekaterina.

With a look of approval, the Golden Dragonfather smiled and said, “Saga, Yekaterina, I have already learned of your performance in the Sky Battle Zone and the Deep Sea Forest Battle Zone.”

“Excellent, your efficiency in handling the dangerous battle zones has exceeded my expectations.”

His expression turned slightly serious, and his projection flickered as he said, “But do not slack off. Quickly pacify the remaining two dangerous battle zones.”

“We don’t have much time.”

Hearing the Golden Dragonfather’s heavy words, Saga frowned and asked, “Father, what has happened?”

He was sharp-minded and felt that something must have changed in the Ginia battle zone. Otherwise, given the current overall improvement in the war situation, the Golden Dragonfather wouldn’t say such things or be in such a hurry.

“You are both capable of handling things on your own now, so there’s no need to hide the bad news from Dragon City.”

The Golden Dragonfather said solemnly, “Behind the abyssal rift in the Ginia battle zone, we have confirmed that an evil god is trying to gather strength to break out of the abyss.”

“A lesser deity—Titan Lord Kros.”

“If it succeeds in descending, its wrath will sweep across the Golden Sea, bringing terrifying disaster.”

Titan Lord Kros, the God of Wrathful Titans, was once part of the Giant Pantheon. Due to his uncontrollable wrathful nature, he inadvertently provoked the higher deity of the Giant Pantheon, the Storm Lord, and was banished with his followers to the first layer of the Casserly Abyss, the Mire Prison layer.

“The God of Wrathful Titans.”

Hearing this, Saga and Yekaterina felt a heaviness in their hearts.

Beings above demigod level would be suppressed by the rules of the prime material world upon descending, only able to exert demigod-level power at most. But not all demigods are the same; deities can exhibit far greater combat power than ordinary demigods.

And not all gods are the same.

A deity skilled in combat could potentially fight ten or even a hundred opponents in the prime material world.

Unfortunately, the God of Wrathful Titans was a deity extremely skilled in combat.

Wrathful Titans are a type of giant, naturally violent and irritable, larger and stronger than ordinary giants, with individual strength surpassing Storm Giants. They are generally stronger than Red Dragons and Golden Dragons of the same age but are very rare.

Though the God of Wrathful Titans is a lesser deity, in the prime material world, he might be stronger than an average intermediate deity.

Moreover, he was sealed in the Casserly Abyss with his followers. If he breaks free, he would likely bring more than one demigod titan with him.

“Dragon City has already informed the other empires of this news.”

The Golden Dragonfather said.

“If the many empires work together, sealing the abyssal rift would be easy.”

“But getting these empires to unite seems unlikely.”

Saga hesitated and said.

According to heritage records, the previous hunt for the God of the Hunt, Mara, was because that deity was too arrogant. After descending to the prime material world, Mara acted without restraint, provoking many empires and demanding all prime material world empires to offer faith, while also inciting followers to cause destruction everywhere, thus angering many empires and bringing about a joint hunt and expulsion.

Initially, no empire wanted to deal with such matters.

The Golden Dragonfather showed a look of disgust and said, “You’re right. Their responses were very perfunctory, meaning that unless they see the God of Wrathful Titans appear and pose a significant threat, no empire is willing to act.”

“In that case, Father, why not retreat to the Dragon Realm and let the abyssal prisoners leave the Golden Sea? Let those empires face the consequences. Deep Sea Dragon City has done enough,” Yekaterina snorted coldly.

“Deep Sea Dragon City has done enough and fulfilled its responsibilities,” Saga nodded in agreement.

But the Golden Dragonfather firmly refused, “No, the abyssal rift was created by Deep Sea Dragon City. We cannot sit idly by, or we would be no different from those empires that only care about immediate interests.”

“Moreover, if the God of Wrathful Titans breaks free, the first to suffer will be the Golden Sea and us dragons. Don’t forget the enmity between dragons and giants. If we don’t stop him, all dragons in the prime material world will face a death threat from the God of Wrathful Titans.”

Gazing at Saga and Yekaterina, the Golden Dragonfather said solemnly, “Saga, Yekaterina, quickly pacify the remaining dangerous battle zones.”

“Gather all our strength and, within the limited time, seal the abyssal rift in the Ginia battle zone to prevent the God of Wrathful Titans from descending.”

“Seeking help from other empires or the Dragon God may not yield a response. Ultimately, we must rely on ourselves.”

“This is a challenge we must face.”

After speaking, the Golden Dragonfather’s projection gradually faded away.

Saga and Yekaterina exchanged glances, seeing the seriousness in each other’s eyes.

“We need to act more efficiently and swiftly pacify the battle zones.”

“Let’s go. Head to the Black Reef Battle Zone immediately. Once we resolve this smallest dangerous battle zone, we should be able to head straight to the Sea Ruins Battle Zone without needing rest.”

Saga and Yekaterina spread their dragon wings and left Deep Sea Dragon City, heading towards the Black Reef Battle Zone.
