Each different race has different resistance, or susceptibility, to the same drug.

The same drug may be highly toxic to some races, but it may be a rare tonic for others.

Moreover, even for different individuals of the same race, the same drug will generally have different effects, and the difference in dosage will make the effect very different.

When dozens or more of the drugs are mixed together, this becomes a difficult problem to solve, even the most skilled healers in the world cannot guarantee that the medicine they have prepared can save everyone, and the poison they have studied can poison everyone.

Therefore, whether you practice medicine or use poison, you need to consider the characteristics of the other party's race and individual, so that your own poison or medicine can exert its due effect, or even exceed the normal level of medicinal power.

At this moment, in the face of the body of the Great Emperor in front of them, all they could do was to first take a part of the various medicines they were carrying, carry them into their bodies by the Subtle Gu, and then record their body's instinctive reaction to these medicines.

Such an attempt lasted for a long time, lasting a whole day.

Chu Feng didn't have any reserves, but Lan Zhi and Chu Zi'er had a lot of reserves.

Chu Zi'er was originally reluctant to take out those medicinal materials, but Chu Feng kept persuading her, after all, she still had no choice, she couldn't endure Chu Feng's soft grinding and hard bubbles, and she couldn't bear to let Chu Feng all her heart alone, so she could only grit her teeth, endure the anger in her heart, and take out her own medicinal materials and start to assist Chu Feng.

The total number of different kinds of medicinal materials carried by the three of them reached more than 3,700 kinds, and every time they tried, Chu Feng would record the next result, and later, even Chu Feng really couldn't record so many results, so he could only let Liwan also start to assist in recording, and classify and sort out the records according to the reaction.

After trying more than three thousand kinds of medicinal materials, Lan Zhi was not ready to give up and began to try his own Gu worm, while Chu Feng began to carefully recall the reaction appearance of the more than three thousand medicinal materials while healing Bing Zhiqi.

Lan Zhi carried a lot of medicinal herbs, and there were also many Gu worms, more than eight hundred kinds of Gu insects took turns to fight, making the little face of Liwan, who rarely saw this on the side, turn pale.

This is not only because Liwan's own injuries are not light, but also because the number of Gu worms on Lan Zhi's body is really terrifying, and the hideous and ugly insects among them account for the vast majority, so how can Liwan not feel frightened?

As soon as Liwan thought that if he carried so many disgusting bugs with him, it would be better to live than die, and he suddenly felt a wave of nausea and let out a retching sound.

Lan Zhi looked at the retching Liwan, the corners of her mouth were slightly raised, and she looked at the black maggot that was circling between her fingers, and her expression was even more proud.

Of course, she knew what Liwan was retching for, but she didn't care—she had seen this situation a lot, and many women of the Wu Clan had stayed away from her habit of raising Gu.

There are not many people in this world who like to play with Gu worms, and women are born with some fear of these insects, so there are naturally fewer women among them, even if they are not afraid of those insects, but for the sake of beauty, how many women let some insects and snakes crawl on their bodies?

After all, even if you are a monk, there are some natures that cannot be changed.

What's more, even among the women who raise Gu, a considerable part of them like to raise gorgeous Gu worms such as butterflies, and only a very small number of people are really full of feelings for the cause of raising Gu, no matter what kind of Gu worms they are willing to raise, and they are even more proud of raising unprecedented Gu worms - and Lan Zhi is this kind of person.

Lan Zhi never minds the gaze from others, what does those worldly boring eyes have to do with her?

Lan Zhi's fingers flicked slightly, poking out the maggot between her fingers and attaching it to the giant snake's shiny scales like metal.

Then the maggot slowly wriggled and crawled towards the serpent's head.

Lan Zhi looked at the body of the giant snake, but there was a little weakness in her eyes.

A considerable number of the Gu worms she brought were eroding the target from the outside in, but at this moment, in the face of the extremely hard scales of this giant snake, she was helpless at all, and could only hope that those Gu worms would gnaw at the enemy from the inside.

But after all, this is the body of the Great Emperor, even if the body of this Great Emperor has long been rotten to the extreme, but the Great Emperor is still an existence that is beyond their reach.

As soon as the vast majority of Gu worms entered the body of the giant snake, they turned into a pool of dirty blood in an instant, and they could not withstand the coercion emanating from the giant snake's body at all, while the other small number of stronger Gu worms, although they could enter the body of the giant snake, were difficult to exert their effects.

Those Gu worms that gnaw at the target's flesh and blood from the body can't bite the flesh and blood as hard as iron at all; the Gu worms that are integrated into the subject's blood are submerged in the blood as soon as they enter the bloodstream, and they are burst and destroyed by the spiritual impact contained in it; those who need to enter the true air flow are directly devoured by the true air flow, and there is no corpse to die......

None of the Gu worms achieved the desired effect, it can be said that it was like throwing small stones into the bottomless sea, without even a ripple.

As for the medicine, although several people have tried more than 3,000 kinds of drugs in total, there are only more than 20 of them that have seen some results - although this so-called slight effect is only because the body of the giant snake has not been able to completely dissolve the effect of the medicine, leaving a little bit of medicinal power in the body of the giant snake, as for what damage has been caused to the truth, it has not yet been done.

Lan Zhi's heart felt a little cold, because she felt more and more that the decision she had made before was too impulsive, and she also thought too much of her own ability.

Even if she started trying it from the time she started, if she really wanted to try something famous, she was afraid that it would take longer than two days, but she didn't even think about it carefully, so she was in a hurry to force Chu Feng to start trying, but she was really too anxious.

But now it's too late to regret it, Lan Zhi knows in her heart that no matter what the result is, it is impossible for her relationship with the people in front of her to go back to the past.

Even if they understand their actions, that doesn't mean that the matter can be uncovered in this way.

Lan Zhi looked at Chu Feng, and finally understood why Chu Feng was really willing to start assisting him, he had expected such a situation, right?

The corners of Lan Zhi's mouth couldn't help but show a little bitterness, although he was older, after all, he had lived a comfortable life in a corner all these years, and rarely encountered real crises, if he wanted to say that his ability to deal with things, he was really still a lot worse than this young man.

Ha, maybe I'm really useless.

Lan Zhi thought helplessly.

Lan Zhi thought so much, but he basically didn't think wrong, Chu Feng really didn't react at the beginning, but in the confrontation with Lan Zhi, looking at the huge giant snake body, he figured it out in an instant.

In front of them was the body of the Great Emperor, and even if they poured all the strongest poison they possessed into the body of this giant snake, it might not really have any effect.

What's more, how much poison is needed to be effective on this huge body?

Can all the medicinal herbs on their bodies add up to that amount?

Lan Zhi was too anxious and didn't want the current situation to produce any more variables, so she didn't have time to think about these problems before she began to make trouble.

But Chu Feng is different, he is relatively calmer, even if he wants to end this disaster as soon as possible at the moment, but he does not need to be responsible for the Wu Clan, he only needs to take the most feasible and safe way to do this, so he can think of this key in time, and by cooperating with Lan Zhi, the crisis of the outbreak of internal strife has been properly resolved.

If he had thought earlier, there might not have been such a conflict between him and Lan Zhi, and now the cooperation between them might still be able to cooperate with each other without so many gaps.

But no matter how Chu Feng and Lan Zhi regretted it, what happened had already happened, and they had no room for redemption.

Chu Feng silently conceived how to rationally prepare the more than twenty kinds of medicinal herbs, so that the medicinal effects that would not be completely absorbed and dispelled by the giant snake's body would be fully buffed and amplified, and the impact on the giant snake would be enough to break the balance.

Chu Feng looked at the huge head of the giant snake and was silent for a long time, his face becoming more and more solemn.

Chu Feng already had more than ten formulas in his mind, each of which was already considered gorgeous, and if it was formulated for ordinary monks, it was afraid that it would be a deadly threat.

But for the Great Emperor in front of him, Chu Feng felt a little powerless, and the elixir refined in this way would not have an effect at all.

Chu Feng needed a more powerful formula, but a more powerful formula often meant a more powerful medicinal herb.

Herbs, he didn't.

Similarly, Lan Zhi does not have such medicinal herbs.

There was nothing they could do, there was nothing they could do with the serpent.

After thinking about it for a long time, Chu Feng came to a final result, there was nothing he could do, all the attempts were just self-comforting, they simply didn't have enough strength to hurt this giant snake.

No matter how much time they were given, there was no way for them to threaten the giant snake, and everything was still moving forward according to the script written by the Spirit Snake Boy.

Chu Feng opened his eyes, looked at the giant snake, and sighed softly.

Then Chu Feng's gaze moved slightly, and Lan Zhi's gaze suddenly met, and from Lan Zhi's eyes, he saw an emotion that he had seen in Su Mengkui's eyes.

That kind of emotion is called despair.
