Chen Mobai opened his eyes.

He took out his phone, which was set aside, and opened the software for measuring spiritual energy.

【Spiritual Energy Value: 89】

How could this be possible? This was already the value of a second-grade top-quality spiritual vein.

Chen Mobai thought there was a problem with the software. After restarting his phone, he placed it on his crossed legs and measured again. The result was that the value had actually increased by two points.

His eyes widened, and he immediately got up, holding his phone, and walked around this side hall dedicated to cultivation.

In the end, he found that the closer he got to the meditation mat, the higher the spiritual energy value.

The peak value was almost close to 100.

“Could this meditation mat be a treasure?”

Chen Mobai muttered to himself, not daring to be negligent, he carefully picked up the meditation mat.

Then he placed it on the ground of the main hall outside and took out his phone to measure it again.

【Spiritual Energy Value: 60】

It was not because of the meditation mat, so there must be a mystery in the side hall.

After controlling and verifying the variables one by one, Chen Mobai found that he was close to the truth.

He returned to the side hall, placed his phone where the meditation mat was previously placed, and measured the spiritual energy value again.

【Spiritual Energy Value: 93】

“This is the place.”

Chen Mobai confirmed that the vigorous spiritual energy close to the third grade was gushing out from this position.

And obviously, Liu Yanpei knew about it, so he placed the meditation mat here, and it was even possible that he had specifically opened this cultivation room for this purpose.

So, what was the reason?

What made this place so rich in spiritual energy?

With a spirit of exploration, Chen Mobai gently extended his finger and tapped the floor tile at this position.

Thump, thump, thump…

He found a hollow floor tile and lifted it up with his absorption technique.

In an instant, a more vigorous and powerful spiritual energy surged out, even turning into a visible white mist, rising like a spiritual snake.

Chen Mobai looked at the screen of his phone.

【Spiritual Energy Value: 112】

It had actually reached the level of a third-grade lower rank. Could this be the source of the spiritual vein of the entire water mansion?

He squatted down, waited for the white mist of spiritual energy to disperse, and the spiritual energy value fell back to the second-grade level. Chen Mobai finally saw the full view under this floor tile.

There was a hollow space, with a palm-sized round black iron plate placed in it. A crystal clear spirit stone was embedded in the middle of the iron plate.

Chen Mobai recognized it. This iron plate should be where the formation plate of the Bi Shui Formation was located.

He didn’t expect it to be hidden here.

The Bi Shui Formation had the function of “gathering spirits”, but even so, it was impossible for a second-grade spiritual vein to leap to a third-grade spiritual energy concentration.

The reason should be this spirit stone embedded in the formation plate.

After confirming that there was no problem with the formation plate, Chen Mobai placed his hand on this crystal clear spirit stone, which faintly showed colorful lights inside.

The moment he touched it, he felt incredible.

A powerful spiritual energy he had never felt before surged into his arm’s meridians and acupoints, causing the skin of his arm to start turning red.

This was a phenomenon caused by his body being unable to bear such a powerful spiritual energy.

Chen Mobai immediately let go of his hand, feeling the numbness in his arm’s meridians after being filled with powerful spiritual energy. He looked at the spirit stone embedded on the formation plate, his eyes burning.

If he was not mistaken, this should be a top-grade spirit stone.

Only the spiritual energy contained in a top-grade spirit stone could be so powerful.

After all, a top-grade spirit stone was equivalent to ten thousand lower-grade spirit stones.

That is to say, the source of the spiritual vein of this water mansion, and even the source of the spiritual power of the Bi Shui Formation, all depended on this top-grade spirit stone embedded on the formation plate.

Was it necessary to spend so much just for a fish and bamboo shoot?

Given Liu Yanpei’s status, he definitely couldn’t apply for a resource like a top-grade spirit stone.

Only the Golden Elixir Taoist master of the Five Elements Sect, who was fond of food, could give out a top-grade spirit stone, just to create a suitable environment for breeding Bi Xue Carp and Jade Bamboo Shoots in Bi Yun Lake.

Chen Mobai hesitated for a long time, but in the end, he covered the floor tile again.

He also wanted to take this top-grade spirit stone, but if he did, this water mansion would basically be ruined.

He estimated that the Jade Bamboo in the next side hall would stop growing due to lack of spiritual energy, and the power of the entire Bi Shui Formation would be greatly reduced due to the loss of the source of spiritual power. He had some feelings for this water mansion and couldn’t bear to destroy it like this.

Another main reason was that this top-grade spirit stone had been activated, and the spiritual energy inside was constantly leaking out.

But because of the restraint of the Bi Shui Formation plate, this leakage was within a controllable range, forming a good interaction with the water veins of the entire Bi Bo Lake.

Maybe after a hundred years, a second-grade top-quality spiritual vein could really be cultivated.

If Chen Mobai were to take this top-grade spirit stone from the formation plate, without the restraint of the entire Bi Shui Formation, it would be like carrying a moving spiritual vein.

Walking on the road, especially in an environment like the Tianhe Realm, it was simply telling the loose cultivators that he had a treasure and they should come and rob him.

“I’ll go back and look up some information to see if there’s a way to reseal this activated top-grade spirit stone.”

Muttering to himself, Chen Mobai brought the meditation mat back in and placed it on the formation plate.

He sat cross-legged, took a bottle of Qi-restoring Spirit Water.

The more rich and pure spiritual energy gushed out from under him, was refined by the Five Elements Technique, and merged into the larger spiritual vortex in his Dantian Qi Sea.

Half a day later, Chen Mobai, who had completed the Five Elements Technique cultivation, once again operated the Transformation Method taught by the Red Robe Taoist master, and began to transform the Five Elements Technique spiritual power into Pure Yang Scroll spiritual power.

After this round of cultivation, he found that the efficiency was indeed a bit higher than before.The increase in his fire spiritual root had significantly sped up his conversion of the five elements’ spiritual power.

Nearly two hours later, Chen Mobai slowly ended his cultivation.

Feeling the five elements’ power maintained at the Qi Refining seventh level, he satisfyingly took out the “Fire-Clearing Pill” refined by Qing Nv.

This was one of the few spiritual pills within the Immortal Gate that could specifically enhance the spiritual consciousness of Qi Refining cultivators.

Qing Nv had already informed him of all the taboos and refining methods for taking the pill. After Chen Mobai mentally reviewed them and confirmed that both his spirit and body were at their peak states, he opened the bottle and poured out a pill.

It was a jade-green pill.

Originally, it was pure white. Knowing that Chen Mobai disliked the smell of medicine, Qing Nv had intentionally coated it with a layer of sugar after refining it. This not only sealed the medicinal smell but also improved the originally ordinary taste.

Chen Mobai naturally didn’t know about this. He just felt that the name “Fire-Clearing Pill” was not wrongly given, it was indeed green.

He opened his mouth to take it, then swallowed it with the warm water he had brought from home.

The medicinal properties of the Fire-Clearing Pill needed to slowly evaporate within half an hour on an empty stomach.

Chen Mobai closed his eyes, using his spiritual consciousness to carefully sense it.

In a short while, he felt waves of coolness rising from his abdomen, flowing into his heart. After being burned by the heart fire, it seeped into his sea of consciousness.

The Mind-Nurturing God-Casting Technique began to operate.

In his visualization, the green sapling that originally only had two tender buds seemed to have been nourished by a light rain, sprouting another green bud once again.
