Zhou Tianfeng put the extracted corpse poison into the bowl, then poured some water, stirred evenly, took out the black syringe, and pulled them all out.

First of all, let's test the amount of injection to see how resistant these ordinary small animals are after dilution.

Zhou Tianfeng selected five hares, injected different doses of corpse poison into the five rabbits one by one, and then began to observe their periodic changes.

Of these five rabbits, Zhou Tianfeng gave them different amounts of corpse poison, but several rabbits showed basically the same poisoning symptoms.

After an hour, several rabbits began to tremble in their legs, and the time difference between them was no more than a minute. Two hours later, several rabbits began to foam at the mouth and began to freeze, and after three hours, several rabbits were completely silent.

After Zhou Tianfeng checked it, he confirmed that several rabbits had died completely, and then began to wait for their next change.

After another hour, several rabbits suddenly got up, their eyes turned dead gray and began to turn corpses, and they became fierce, their teeth bulged, and they began to bite the iron cage.

Zhou Tianfeng experimentally began to attack them with a knife, his skin and hair were a little stiff, and his defense was stronger than before his death, but he couldn't feel pain, and what flowed out was not normal blood, but a black-gray liquid.

Could it be that the dosage used has nothing to do with the symptoms of poisoning and corpse? The time of death and corpse transformation of several rabbits is basically the same.

No, I need more data.

Zhou Tianfeng controlled a few rabbits, and then extracted the corpse poison blood from their bodies, as well as some corpse poison on their fangs.

The carcass poison extracted from the hares was then injected into five other healthy hares.

They began to observe the changes, and after an hour, several hares did not show any reaction, after two hours they began to show some symptoms, and after four hours, the hares began to convulse and fell to the ground, foaming at the mouth.

Five hours later he began to die, and another hour later there was a mutiny.

From the death of infection to the corpse transformation, it took six hours before the corpse transformation began, Zhou Tianfeng once again extracted these corpse poisons, and then injected them into the healthy hare again.

This time it took two hours for the five hares to begin to show symptoms of infection, and they did not die until a day later, and then began to mutate an hour later.

Zhou Tianfeng once again extracted a more diluted corpse poison and re-injected it into the five healthy hares.

The third round of experimental hares, after a full day, began to show some symptoms of poisoning, began to fall to the ground, convulsions, and did not die until the next day, but this time, these hares did not have a corpse.

Once again, the hares that had done the fourth round also began to show symptoms, but this time only two died, and three survived, albeit a little weak.

This corpse poison can be diluted, but it was just that it was not diluted thoroughly before, or its own way was a little rough.

The intensity of the infection will gradually decrease, and it will not mutate, or even die.

So now to test whether they will develop immunity, Zhou Tianfeng fed the three surviving rabbits some elixirs and let them recuperate for a while.

Zhou Tianfeng began to experiment with mice, which was exactly the same as the experiment of rabbits.

A few gray rats, the corpse transformation time is longer than that of rabbits, and the rabbit will only be corpsed after four hours of poisoning, but a few gray rats will survive for six hours before the corpse transformation.

Then Zhou Tianfeng concocted the same method, using the corpse poison on these dead rats to infect several other normal mice, and their death time and corpse transformation time were also postponed by about double.

A third dilution experiment was conducted again, and this time, all the mice were dead but not dead.

After that, Zhou Tianfeng performed a fourth round of dilution, and this time several mice showed symptoms, but did not die.

Zhou Tianfeng also saved these surviving mice, and fed them some elixir, and fed them together with a few surviving rabbits.

A month later, these surviving animals successfully returned to a healthy state of life, and Zhou Tianfeng began the second round of experiments.

To test their immunity, this time Zhou Tianfeng used the most primitive corpse poison that was practiced from the two corpse puppets.

Zhou Tianfeng injected them into the hares, which had previously been infected with a diluted version of the corpse poison, as well as rats.

However, the results of the experiment disappointed Zhou Tianfeng, the time of the death of the hare was exactly the same as that of the first batch of hares, four hours, there was no deviation, and the same was true for the mice.

Even though they had been infected with a weak version of the corpse poison once, these animals had no immune effect at all.

After being infected with this corpse poison, an antidote must be used to remove the corpse poison, and the life here cannot be immunized according to the methods of life on earth.

Zhou Tianfeng extracted the corpse poison from the last batch of experimental rabbits and injected it into his body.

This corpse poison has been weakened to the extreme, and it is a safe corpse poison vaccine extracted by Zhou Tianfeng after sacrificing dozens of hares and mice.

Of course, this thing only works on life on Earth.

After the corpse poison vaccine was injected into his body, Zhou Tianfeng did not feel any discomfort, and his body did not have convulsions and foaming at the mouth, and a day later, Zhou Tianfeng successfully immunized against these corpse poisons.

And the corpse poison of the two corpse puppet mothers has no effect on Zhou Tianfeng.

Let's start the third round of conjecture experiments.

Zhou Tianfeng extracted all the corpse poison from these experimental hares and mice, and then injected some of his own saliva, while the maternal corpse poison added some of his own blood, and then he had to confirm the viruses and bacteria on his body.

I'm going to see what happens when these corpse poisons combine with their saliva and blood! Will the bacteria and viruses on your body cause some unexpected changes to these corpse poisons?

Next, he still needed some new experimental subjects, and Zhou Tianfeng immediately ordered to let the outer disciples go and catch some small animals and come back.

However, this time, a few outer disciples grabbed some experimental materials for Zhou Tianfeng, which made him unexpected.

"Who are these?" Zhou Tianfeng asked a little speechlessly.

I saw that on the ground, there were four soldiers with big flowers and black armor.

"Fourth Master, didn't you tell us to catch some animals that you want to test for poison? It just so happened that this time there were four Tiance troops operating in the Tianjiao Mountains, so let's catch them, hehe! ”

"......" Zhou Tianfeng.

You guys are amazing!
