Today's test was another major failure.

In order to provide You Yonghuai with a medical examination, Ling Xiuqi specially released two researchers from the laboratory temporarily to help install the medical examination equipment.

The laboratory's full-body examination equipment doesn't take up much space and can be temporarily installed and used in the police station's open area.

After a full-body scan and several vials of blood were drawn, Ling Xiuqi stood aside, monitoring the two researchers as they operated the equipment.

After the test data came out, Ling Xiuqi didn't let the two researchers analyze it and give the results. Instead, he took a picture and sent it to Su Rou directly.

About thirty minutes later, Su Rou sent several voice messages and a document.

"The child is perfectly healthy and there are no hidden dangers."

"But he should have a partner, or someone he's very close to? Anyway, please ask him if he's ever exchanged blood or anything like that with someone."

Upon hearing this, Ling Xiuqi turned to look at You Yonghuai and raised an eyebrow.

That's quite a fancy way to play.

You Yonghuai and Si Xuanyin exchanged a glance, then realized what Su Rou had said.

Previously, in order to enhance his spirituality, You Yonghuai had drunk Si Xuanyin's blood.

Last night, in order to awaken Si Xuanyin, You Yonghuai fed her his own blood.

Su Rou's voice message is still playing:

"If so, please tell them that their bodies are very compatible, and further integration would be of great help to both of them."

"If not, then tell the child to be careful; someone might be watching him."

"I don't know the method of integration either, I only know that the souls of the two people must also be exchanged, so that they can truly be in each other's hearts."

You Yonghuai and Si Xuanyin looked at each other in bewilderment.

Good news, what Su Rou was referring to should be the condition for fulfilling the "Ouroboros" trait.

The bad news is, I still don't know how to make up for it.

"That's a very mysterious statement," Si Xuanyin said, scratching her head.

Are we supposed to bite off each other's souls?

Hearing what Su Rou said, You Yonghuai didn't have any particular feelings, but Si Xuanyin's somewhat strange idea inexplicably surfaced in his mind.

Before he could even think about how he knew Si Xuanyin's thoughts, You Yonghuai's attention was drawn to Su Rou's next words. He could only glare at Si Xuanyin to tell her not to overthink things.

Don't let any strange things get into my head.

Si Xuanyin understood the meaning behind You Yonghuai's glare, stuck out her tongue, and stopped talking.

"There's something even more important—among the encrypted documents from the lab that you sent back, there's a document about the source of life."

"I've also sent you a copy of the document, which roughly outlines the production process and the function of the Source of Life... but there's one crucial point:"

"The source of life will not be absorbed by any individual other than the pre-selected person."

Ling Xiuqi's lips twitched, and he looked at You Yonghuai again.

You Yonghuai himself looked incredulous. He remembered the guy in the lab who was pretending to be a deliveryman calling him "Perfect Body".

"There are two possibilities: either the source of life is not yet complete and does not have this characteristic, or You Yonghuai himself is the target chosen by the laboratory to absorb the source of life."

"Personally, I prefer the latter, so Ling, keep a close eye on Xiao You and don't let him get kidnapped by the lab people... If anything happens to him, I'll hold you responsible."

"Do I really need you to remind me of something like this..." Ling Xiuqi glanced helplessly at You Yonghuai, wanting to temporarily imprison the guy.

But imprisonment was just a thought; Ling Xiuqi would never actually do it.

After all, even if You Yonghuai is locked up, the laboratory's evil plans probably won't end.

If a villainous organization's plan is to imprison key figures and then halt its progress, that organization is unlikely to survive long.

Not long after, Su Rou sent another voice message:

"I've applied for it. To give Xiaoyou some self-defense skills, we can give him a skill book directly."

"I took the liberty of picking them out for him first. Anyway, they're not really any impressive skills, and I don't have time to let you leisurely pick these things out."

"Remember to help Xiaoyou improve his spirituality. His current spirituality is definitely not enough, no matter what skills he has."

Then, a file was transmitted. Ling Xiuqi glanced at the title and forwarded it to You Yonghuai, saying, "It might be useful to you."

You Yonghuai picked up his phone and saw that the file was named "Fireball Technique".

"That's great, we won't need a lighter when alchemy catches fire anymore," Si Xuanyin said, half-jokingly.

"Alright, you can go back now. Hurry up and master this skill... although I don't think it will be of much use." Ling Xiuqi waved his hand and didn't let You Yonghuai stay any longer. "If you really have nothing to do, come and come with me to Wenjiang Middle School."

After leaving the police station, You Yonghuai did not go home immediately, but went to the business hall first to get Si Xuanyin a new phone card.

He used his ID card.

Afterwards, he went to the digital mall and bought a mobile phone and a laptop, also for Si Xuanyin.

The girl showed no intention of saving money, spending 20,000 yuan on the entire set.

However, since Si Xuanyin would be the main source of income in the future, You Yonghuai naturally wouldn't care about her expenses.

Since Si Xuanyin said she could earn it back, let her spend it as she pleases.

Just make sure he can afford to eat.

The alchemical materials that You Yonghuai had previously purchased from the fat man had actually been delivered to him long ago, but he had not used them due to his bad luck.

Now that Si Xuanyin has recovered, we can use her.

"I'll make some recovery potions, and we can exchange the extras for money, is that okay?" Si Xuanyin asked You Yonghuai as she tied her long hair into a high ponytail. The latter naturally didn't object.

The two went into the master bedroom and guest bedroom respectively and began to do their own things.

As for the issue of telepathy, neither of them understood the underlying principles, and for the time being, they simply regarded it as a convenient ability.

Sitting at his desk, You Yonghuai took a small knife and mercilessly made cuts on his body, collecting his blood.

"Why do I feel like I have autism..." Yu Yonghuai muttered to himself as he recalled the contents of his notebook and began to enhance his spirituality.

With the source of life, before the life force within it is exhausted, You Yonghuai can freely harm himself and transform the life force into his own spirituality.

Of course, he and Si Xuanyin were already prepared to move the "Eye of the Evil God" to the next stage.

As his spirituality rapidly increased, the "two birds with one stone" effect also began to take effect, and Yu Yonghuai's inspiration rose along with it:

Spirituality: 15.5 → 32

"Kill Two Birds with One Stone" in effect: Inspiration: 18.5 → 45

The next stage of "Eye of the Evil God" has been unlocked.
