Su’en agreed to the transaction with Number 19.

But because he couldn’t delay the work of drawing runes on the undead, he didn’t stop.

Number 19 also watched quietly on the side.

The two of them were silent for a while.

Before long, they finished their work.

Because he was already skilled, Su’en didn’t take much time to draw the runes on the abomination warrior’s body.

To his delight, after the runes were drawn, the vital signs of the corpse stabilized.

This meant that he had successfully created an “abomination undead”!

He tested it with a sharp dagger, and the muscles were incredibly resilient. After stabbing it forcefully, the exaggerated regenerative ability was just like when it was alive, instantly healing the wound.

Seeing this, Su’en let out a long breath.

He really struck gold on this little outing.

When Chekhov wrote “Undead Research Diary,” he was researching how to revive humans normally, so he probably didn’t expect that a “hateful warrior” with a certain special distortion could also be made into an undead.

With this “abomination undead,” the Reaper became a super killing weapon in Su’en’s hands.

…….

After Su’en finished working on the undead, a three-meter-tall corpse paired with a two-meter-long black scythe was a perfect match, exuding a sinister aura!

Because Number 19 already knew about the two forbidden items in her possession, she didn’t deliberately avoid them and wrapped the corpse and scythe together with a shroud.

Although Number 19 did know the information and had witnessed the killing of the enemy who was also a mechanical warrior with this corpse and scythe, she still showed a hint of surprise when she saw the massive abomination corpse and the black scythe suddenly disappear from her sight.

It was hard to imagine who could withstand this “invisible killer” if caught off guard.

Number 19 said with a complicated expression, “The internal intelligence of the Umbrella Organization said that you have mastered a method of using the [Nocturnal Black Scythe of Sopnos] without fear of backlash. So, this is how…”

Su’en didn’t explain much because it wouldn’t be meaningful for others to know without the research knowledge from the “Undead Research Diary.”

Now that his own affairs were settled, he could start discussing the transaction.

He took out the mechanical corpse of the soldier and asked, “How do you want to replace your mechanical limbs? I’m not very proficient in mechanical knowledge, but I can be considered an intermediate-level mechanic…”

“That’s enough.”

When Number 19 heard that Su’en was an intermediate-level mechanic, she was pleasantly surprised.

She said, “If it’s just installation, you don’t need advanced mechanical knowledge. However, this ‘power-type mechanical limb’ doesn’t quite match my design framework, and it’s a new generation of machinery, so some accessories need to be modified to make it barely usable… I have the materials in my storage ring, and the severed arm also needs to be disassembled to replace some parts…”

Su’en also felt that the soldier’s mechanical skeleton was one size larger than Number 19’s, and the difference was significant. He curiously asked, “Power-type? Are there different types of limbs for mechanical warriors?”

Number 19 briefly explained, “Yes. There are ‘PZ power-type’ and ‘PX skill-type’ two models, which focus on different combat styles.”

Just by hearing the names, Su’en roughly understood the difference between the two models. He suddenly remembered the small-sized limbs in his storage ring, but they seemed different from Number 19’s. He asked, “Is it the [PX-911 Mechanical Limb] that you need?”

Number 19 shook her head, “No, although the PX series are all skill-type. Mine is the old version of [PX-811], so some parts need to be replaced.”

“Oh…”

Su’en thought for a moment and said, “Can you install the [PX-911 Mechanical Limb]?”

“???”

Number 19 was confused by what he said and didn’t understand the meaning.

Su’en took out some parts of the [PX-911] and said, “What I mean is… I accidentally obtained a [PX-911 Mechanical Limb] before, but I can’t use it. I disassembled it, and it should still be intact. If you need this model, I think we can exchange for it.”

Seeing the parts that Su’en took out, Number 19 was also stunned for a moment, feeling a sense of surprise and disbelief, “911 is the latest model of mechanical limbs developed this year… You actually got one?”

Su’en briefly mentioned, “Yes. On the day you blew up the West City Laboratory, I accidentally intercepted a transport vehicle and found this mechanical limb. If you need it, we can include it in the transaction.”

“Okay.”

Although Number 19’s expression remained the same, her tone of voice clearly showed emotional fluctuations. “If it’s this one, it’s naturally better.”

Su’en also didn’t mind, thinking that the soldier’s corpse with a head was more suitable for research. He asked, “How should I help you replace the limb now?”

Number 19 lay flat on the ground and said, “First, help me with one of the mechanical arms, so I can also assist.”

Su’en asked, “Should I remove the alloy plate armor on the chest first?”

Number 19 nodded, “Yes.”

…….

Although Number 19 was a mechanical warrior, except for the visible mechanical parts at the shoulder joints where the arms were severed, there was no difference from a real person in other places. The synthetic skin was delicate, and even pores and blood vessels could be seen.

Of course, in some places where there were minor damages, there were traces of scattered metallic luster.

Su’en had already disassembled and studied the mechanical limbs in detail before, so he was not unfamiliar with the tools and directly started working.

“Do you mind if I cut your clothes to remove the alloy plate armor?”

“No. You can go ahead.”

Both of them spoke calmly, without any unnecessary emotional fluctuations.

Number 19 was wearing a black gothic-style one-piece ultra-short skirt, with large lace hollows on the chest. Even when lying down, it still had a proud undulation.Because it is a mechanical body, her body proportions are completely built according to the golden ratio, whether it is the waist-to-hip ratio or the leg-to-body ratio, it looks very perfect. Especially the hip line, it makes people feel that the pair of white legs wearing black high-heeled boots are particularly slender and three-dimensional.

Su’en’s face showed no surprise as he calmly cut open the black dress.

“Snip, snip” The sound of scissors cutting through the fabric was particularly clear in this dim dungeon.

When cutting the clothes, Su’en’s fingers accidentally touched the synthetic skin of No. 19, tight and bouncy, just like real human skin.

This was his first time encountering such advanced material.

As a novice alchemist, he naturally had some curiosity about this material. The skin was like latex, but tough enough, and it felt smooth between his fingers.

Looking closely, there were obviously many alchemical techniques and black technology that he couldn’t understand.

From the chest, to the abdomen, and then to the skirt.

Until this broken mechanical body was completely exposed in the air…

Then came the lace underwear.

One second before cutting, Su’en thought that the body under her clothes should only have a rough shape, without any details. But after completely cutting the clothes, it turned out to be exactly the same as a real person.

Even without the damaged parts, this well-proportioned body could almost be said to be a flawless work of art.

No. 19 seemed to have guessed Su’en’s doubts and didn’t avoid them at all. With a calm tone, she explained, “There’s nothing strange about it. Synthetic limbs were originally invented to meet some special needs of men. And in order to avoid easy exposure during missions, the appearance of our mechanical soldiers is not much different from normal humans.”

“Oh.”

Su’en raised an eyebrow as he listened.

Suddenly, he understood some of the runic marks on the skin and asked, “Can this synthetic skin also provide optical invisibility?”

No. 19 didn’t avoid the question either and responded, “Yes. It is made of light-absorbing material, with high magic resistance and toughness. Optical invisibility is just one of its functions.”

“Oh.”

Su’en curiously asked a few more questions but didn’t say much.

He touched the mechanical joints under the synthetic skin with his hands and began to dismantle the alloy plates with his hands.

“Can the synthetic skin be destroyed?”

“Yes.”

Su’en asked and started to work.

There was no abnormal emotional fluctuation in his eyes even though she was naked, just like when he was dismantling the mechanical limbs in the basement.

Both of them were very calm.

No. 19 looked at his skilled technique and sighed, “Your technique is very proficient. I thought you would need my help.”

Su’en said, “I have studied it before when I dismantled it. I roughly remember…”

“What energy source do mechanical soldiers consume?”

“Cursed crystals. If it’s intense combat, it requires high-quality crystals.”

“Do you have any food requirements in daily life?”

“The brain needs necessary glucose for energy, so I usually supply some nutrient fluids.”

“How are the nerves connected to the machinery? Is it technology or special alchemical prosthetics?”

“Both. But even the Black Tower hasn’t mastered the technology of connecting nerves to machinery. Later, some special substances were extracted from the ‘X Serum’, which made the ‘Super Soldier Project’ possible. However, large-scale modifications still cause strong rejection from the human body towards mechanical limbs. That’s why there aren’t many super soldiers. I was the only one who survived among the first batch of test subjects, probably less than a 0.3% chance…”

“Oh. Are the people you killed all related to the ‘X Serum Project’? Before I came here, I heard that you killed an intelligence officer named House…”

“Yes. Illegal population collection, that was House…”

…”

While operating, Su’en chatted with No. 19.

He was very curious about the structure of the mechanical soldiers, and now that he had analyzed a complete one, he asked all the questions he had.

He also asked about the details of her crimes and some insider secrets of the Black Tower.

Time flew by as they chatted.

Originally, it was just replacing two arms, but now they had changed the entire set of new mechanical limbs, including the legs and body.

In no time, Su’en replaced No. 19 with two new arms, and she could also help with some mechanical parts on her own. The two of them cooperated tacitly, and in less than two hours, they had replaced most of the limbs.

There were still some delicate parts and damaged synthetic skin that needed time to be dealt with. No. 19 said she could handle it herself.

Su’en took off the synthetic skin from the military man’s body and gave it to her as well.

…….

Perhaps it was because they had been chatting for a long time, or maybe it was because they had become more familiar with each other.

No. 19 stood up again, and her face was no longer the cold expression of a robot when they first met. Her words and actions were friendly.

She tried to move her new px911 mechanical limbs and found it not awkward at all. Although her arms were still completely exposed metal skeletal limbs, she seemed to feel good.

She was satisfied.

“Thank you.”

“No need to be polite. It was our agreed-upon deal.”

“Let me give you another piece of information. When you go to Dawn City, pay more attention. There are also many members of the Umbrella Organization there. I intercepted a secret intelligence before, and the ‘Dawn City Ruins’ were discovered because a big shot from outside the tower went to search for some legendary altar and accidentally found it. The news was intentionally spread by the high-level of the Black Tower. Apart from developing the ruins, Duke Raphael seems to be looking for something in there… Soon, there will be a large-scale hunt for lies in the inner city, and more high-level professionals will come…”

“A big shot from outside the tower?””Um, there’s no more information. All we know is that it came from the Duke’s mansion, seems to be a young master.”

“…”

Upon hearing this news, Su’en suddenly understood who was hunting the “original owner”.

The two didn’t say much more.

Before parting, Number Nineteen thought for a moment and added.

“I owe you a favor this time. If we meet again, I’ll repay you.”

“Um.”

Watching her disappear into the depths of the cave, Su’en also turned and left.

PS. Thanks to the bug-catching buddies, you’ve helped the rookie author a lot, thank you very much.
