A year has passed in a hurry, and in this year, Xiao Jiu has become a famous genius in the academy.

When the teachers mentioned him, they would say that he was "comparable to the master of Hossente back then" and "another Hoscent is about to be born", which made him extremely unhappy, but he also changed from anger to silence under Yan Ruyu's persuasion.

He didn't have the strength to refuse that name now, he endured.

I don't know if it's an illusion, he always feels that Yan Ruyu looks down on Hosant just like him.

In the past year, Yan Ruyu has more and more buyers, and her potions have replaced the regular channels as the top priority for small traders to buy goods.

Horcente's customer base is positioned as a nobleman with a lot of money and stupidity, and the two do not have much interest entanglement for the time being.

Or maybe Horson didn't take Yan Ruyu's petty fights seriously.

Walking the streets and alleys to earn those poor people's money, or at such a low price as 20 gold coins, he didn't think Yan Ruyu could do anything extraordinary.

In his opinion, the foundation he has laid over the decades is not so easy to shake.

Just let her toss some pocket money.

Yan Ruyu is not in a hurry, she continues to do wholesale while raising children, usually in addition to making potions, the thing she spends the most time on is to study the strange injury on Xiao Jiu's back.

After a long time, she found that this strange thing was only afraid of medicine.

Taking off her mask, she looked at the latest potion and her eyes sank.

Hosson is indeed a madman, and Kojiu and the children he used for experiments were implanted with a special substance by Watson.

Yan Ruyu had been to Horst's laboratory a few more times, and she found that the old guy hadn't paid much attention to the potions recently, because he was concentrating all his energy on another research - immortality!

He's studying the secret of the witch's immortality.

The substance that was planted in the boys' bodies was extracted from the blood of the original owner.

The witch's special ability comes from the bloodline, and Horson started to study it from her blood, and the direction is not wrong.

But the body of an ordinary person simply cannot withstand the power in the blood of the witch.

In a short period of time, they will become smarter, stronger, and their reflexes and learning ability will be greatly improved.

But over time, the backlash of the blood will begin, and the ulceration of the body is one of them.

The mysterious substances in the blood will provide their bodies with great strength while also oversqueezing their life force.

Once the host's body is unable to provide them with more nutrients, these mysterious substances will riot and drag down the body due to unrestricted absorption, causing organ decay and body collapse.

After thinking about this, Yan Ruyu quietly took away the "antidote" that Xiao Jiu had hidden.

There are many ingredients in the antidote, but the key thing is her blood, which is a palliative solution.

The mysterious substance extracted from the blood will damage Xiao Jiu's body every certain amount of time, and the self-healing ability of the new blood can repair the damage, which sounds like an endless competition.

This method is not something that can be used by just anyone, for example, the children in the laboratory cannot tolerate excessive intake.

Although Xiao Jiu is better than them, after a long period of suppression, the consequences of the final backlash will also increase exponentially.

The more blood there is in his body, the more his potential is stimulated, and when his body's capacity reaches its limit......

Unless a way is found to make Xiao Jiu accept her blood, one day after this balance is broken, Xiao Jiu's body will still collapse.

At that point, there will be no cure for him.
