Sure enough, as the Blood Shadow Ancestor expected, the next day, the little fox came to class as usual, and he was still able to exchange ideas with Zhou Tianfeng during the period.

However, in terms of cultivation and study, the little fox has obviously worked harder, and is more diligent and assiduous than before.

The Blood Shadow Ancestor was right. A little setback, but it's a good thing for this little girl.

In the next month, Zhou Tianfeng began his life at three points and one line, went back to his room to rest and meditate and practice, went to the library to read, and studied with the Blood Shadow Ancestor.

A month later, Zhou Tianfeng's cultivation successfully broke through and reached the middle stage of condensation, and he was no longer the rookie in the early stage of condensation.

After the breakthrough in cultivation, Zhou Tianfeng's physical fitness was stronger than in the early stage of Qi condensation, and his cultivation was even more exquisite.

In this month's time, the two toxins that Zhou Tianfeng was immune to before, the Blood Shadow Ancestor also experimented, and after Zhou Tianfeng took the absolute lethal dose, there was nothing wrong with a few days, and it was the same as a normal person.

Sure enough, he has been completely immune to this poison and is no longer afraid.

In the eyes of the Blood Shadow Ancestor, it was the poisonous spirit body that successfully dissolved the two poisons, which made Zhou Tianfeng's body no longer afraid of poison, but Zhou Tianfeng understood that it was the immune system that had recorded the various characteristics of the poison.

When these highly toxic substances enter their bodies for the second time, they immediately launch a targeted attack, and these highly toxic substances do not have time to exert their effects, they will be immediately caught by the immune system and then killed.

As long as you have been defeated by your own immune system once, then you don't want to have a second chance, the life form from the earth, the immune system is so inexplicable, powerful and domineering.

Damn, Lao Tzu can also be a man who eats poisonous snakes as spicy strips in the future, cough cough! No, no, in that case, wouldn't you be going to become a flat-headed brother?

Anyway, I knew that I was going to cross over, and I should have made a flat-headed brother to wear on my body before, brought it to this world, and then let it evolve into a demon race, I don't know what a magical thing it will be.

In short, it must be hilarious.

After the Blood Shadow Ancestor's class ended today, it was the day when Zhou Tianfeng took the poison again, this time it was not just the Blood Shadow Ancestor and Zhou Tianfeng, but the little fox was called to observe from the sidelines.

The little fox was also very curious about how Zhou Tianfeng's poisonous spirit body dissolved the poison, and wanted to see this legendary physique up close.

For the little fox's request, the Blood Shadow Ancestor naturally did not refuse.

"What a disciple! Now you can take the third poison, this time, as you said, the poison has been diluted, and the current dose can be poisoned to death at most, an ordinary person, as long as he has a little cultivation, can bear it, and have time to find an antidote. The Blood Shadow Ancestor took out a small bowl, then took out a small bottle and dripped a drop of pink liquid on it.

This is the poison he diluted before, only 1/10 of the original amount, which is not enough to make a monk in the middle stage of condensation die, but if it is an ordinary person, or a monk in the body quenching realm, then hehe, it is still certain to die.

Come, my good apprentice, let me see if you can really dissolve this poison in this way?

Zhou Tianfeng nodded and took the small bowl, which contained a drop of pale pink liquid, which was the poison of the Blood Shadow Ancestor after dilution.

This is the highly toxic vaccine that I have created according to the simplest vaccine on the earth.

In fact, Zhou Tianfeng also knows some other vaccine production methods, but it obviously doesn't work in this world.

Because of the denuclearization of cells, directly killing the virus, and then injecting the dead virus into the body to make an inactivated vaccine, he didn't have that level to operate!

And this is highly toxic and not a virus, people are not a system at all, and naturally they cannot make inactivated vaccines, so in the future, they can only dilute the virulence at most, and then immunize.

"Cut, you are really cowardly, you have diluted the amount of poison to this point, even an ordinary monk can't poison to death, you poisonous spirit body is still afraid." The little fox said mockingly.

She despised Zhou Tianfeng's fear of death, please, you are a legendary poisonous spirit, and I haven't heard of a precedent for a poisonous spirit to be poisoned.

The poisonous spirit body is the nemesis of all the poisons in the world, and now you are actually afraid, and you actually want to dilute this poison to a certain extent before taking it, it is really a shame for the poisonous spirit body.

"You know what? I call this cautious, and my poisonous spirit body does not need quantity, only a little bit, I can be immune to this poison, so why should I take a lethal dose? Zhou Tianfeng retorted.

"Aren't you just scared? If I have a poisonous spirit, no matter what kind of poison it is, my aunt and grandmother will still dare to eat it. The little fox spoke.

"Huh! It's a pity you don't. Zhou Tianfeng said with a smug smile.

"You! You, huh! The little fox was so angry that his cheeks bulged, his eyes were red, he glared at Zhou Tianfeng angrily, the two snow-white pointed ears on his head were also erected, and even the tail behind his back began to swing non-stop, obviously very angry.

Damn it! Got it by this bastard again.

"Okay, okay, girl, it's a good thing that your fourth uncle is so cautious, at least a cautious and cautious person can live longer in this cultivation world, and the more high-profile and arrogant people are, they won't survive to the end." Blood Shadow Ancestor said.

"Did you hear that? Or the master understands the reason. Zhou Tianfeng said.

"But being overly cautious is not a good thing, sometimes it is very likely to miss some opportunities, so the kid needs to be cautious when he should be cautious, but when he should rush, he also needs to rush up to compete for the opportunity, we cultivators are going against the sky, but we can't be cautious in everything." The Blood Shadow Ancestor directly hit 50 boards each, neither towards Zhou Tianfeng nor towards the little fox.

"It's the master, and the disciple obeys the teachings."

"Humph! Coward. ”

"Alright, let's take it quickly! Let the teacher see if it works. Blood Shadow Ancestor said.

"Hmm!" Zhou Tianfeng nodded, and swallowed the drop of pink liquid in the small bowl directly into his abdomen.

After the diluted poison entered the body, it was immediately discovered by the immune system, and began to chase and intercept this poor poison in all kinds of cruel and inhumane ways.

Eventually, these weak, pitifully diluted versions were wiped out by the immune system in just a short time.

And what about Zhou Tianfeng in the outside world? This time, there wasn't even a drop of sweat on his head, and there was no on the whole person, as if he hadn't been poisoned at all.

The Blood Shadow Ancestor observed for two days and one night in a row, and only after personally confirming that Zhou Tianfeng had nothing to do did he put his mind at ease.

God, this kid's method is really useful, the poisonous spirit body can actually play like this, this has to be written down and recorded in the classics of my sect.
