After the success of the first attempt, Lin Yiran planned to still use the same medicinal materials to refine the poison, but this time he wanted to add his own blood to see if he could refine the unique poison he wanted.

As usual, when he was refining the poison, he had already memorized the changes in the medicinal materials during the refining process, so it only took an instant to refine the two medicinal materials.

Next, when he was knotting the pill, he added a drop of his own blood to the refined medicinal liquid, and then prepared to start the process of knotting the pill.

Unfortunately, not long after he poured blood into the liquid, the pale green liquid suddenly became transparent, and he could feel that the toxicity in the liquid medicine was gone. Fortunately, he had been paying attention to the changes in various medicinal materials, so he knew that this was because the toxicity of the medicinal materials he used was too low, so after his blood was added, the toxicity of the medicinal liquid was neutralized by his blood.

Lin Yiran knew that if he wanted to add his own blood to the poison and maintain enough toxicity, he needed more toxic medicinal materials as raw materials.

Although he understood the reason for the failure of refining before, he still didn't dare to directly use the four raw materials he had just bought to conduct experiments. And the poisonous herbs left by Feng Yangcheng were not very toxic, but in order to confirm his idea again, he could only select two of the most toxic medicinal materials suitable for refining together for experiments.

This time, after refining two medicinal materials one after another, Lin Yiran directly added a drop of his blood to the medicinal liquid. It's just that what makes him wonder is that this time the liquid medicine only lasted a little longer than the previous liquid medicine, and in the end it became completely toxic.

But correspondingly, he also proved that his previous idea was correct through another experiment.

Next, he planned to directly use the two medicinal materials he had bought before to refine the poison. When he was checking the properties of these herbs before, he found that the medicinal properties of the Broken Intestine Herb he bought before were sweet, which happened to be compatible with the salty mother Cordyceps, that is, if he used two medicinal materials to refine the poison, it could just increase the toxicity of the poison.

Lin Yiran simply beckoned the box containing the mother cordyceps and the broken intestine grass, and then opened the box directly. He is not afraid that the Mother Cordyceps will attack him, after all, this is his inner world, and the Mother Cordyceps will not cause him any harm at all.

As the box containing the mother cordyceps was opened, the mother cordyceps regained her freedom and soon turned into a small insect.

Lin Yiran hesitated for a moment, and finally threw the Broken Intestine Grass into Shennong Ding, although he had already understood the basic pharmacology and had done the corresponding experiments, but this was also the first time he had refined a very toxic poison, so he was still a little afraid of wasting these two valuable medicinal materials.

He thought about it carefully, and felt that refining poison was not as complicated as refining pills, as long as it was refined according to the general refining process and basic principles, it would generally not fail, unless it was refining poisons with special effects, it would have special requirements for the refining process, and he just wanted to refine the poison that only he could decommit, so generally speaking, it should not fail, and finally threw the broken intestine grass into Shennong Ding.

In fact, after discovering that alchemy was a very simple thing for him, Lin Yiran's mentality had changed, and he was no longer so afraid of wasting these precious medicinal materials, because he felt that with his own ability, it should be no problem to earn a large amount of space by refining pills.

And he now felt that even if the refining failed, he could still gain the corresponding experience, so it couldn't be regarded as a waste.

After figuring it out, Lin Yiran began to calmly refine the Broken Intestine Grass. After a while, he succeeded in refining the Broken Intestine Grass.

Then he moved his mind and threw the mother cordyceps into the medicine pod, and began the refining process. The same process was quickly and successfully completed, and then without hesitation, he squeezed out a drop of blood from his finger and dripped it into the Shennong Ding.

Then Lin Yiran had a thought, and directly mixed the two medicinal liquids with his blood, and the two medicinal liquids, which were originally green and black, suddenly boiled, and the color turned black and green, emitting a foul smell.

The smell was so strong that Delin couldn't help frowning, and then with a move of his mind, he changed the direction of the smell, and then he felt better. He didn't dare to completely isolate the stench, after all, he didn't know if doing so would affect the refining of the poison.

As time slowly passed, the boiling state of the medicinal liquid gradually intensified, until they produced a detonation, and they were suppressed by the special effect of Shennong Ding. And Lin Yiran didn't dare to form a pill in this state, because as far as he knew, the process of forming a pill could only be carried out when the medicinal liquid was completely calm.

And he had never seen this kind of scene at all, so he didn't dare to forcibly suppress the boiling liquid, and he could only wait quietly for the liquid to calm down on its own.

As time passed, the potion became darker and darker, and the stench became stronger and stronger—of course, he felt it by special senses.

The liquid boiled for an hour before it slowly cooled down, and then it took more than an hour for him to completely calm down, and only then did he dare to start the pill.

However, he found that the toxicity of the liquid medicine at this time seemed to be quite strong, if it was directly given to the meat man and the monkey, he might be killed on the spot, in order to prevent this accident from happening, he divided the liquid medicine into four parts, and formed four pills, with his keen sense in the inner world, he was sure that one pill would definitely not be enough to kill them.

It's just that it's the first time he's refining poison, and it's just a casual recipe, so he doesn't know what the effect of this stinky poison is, if letting the crossmeat man and the monkey take a poison pill will affect their strength, then they can't be his right-hand man.

Thinking of this, Lin Yiran began to hesitate whether to simply find someone else to help him prepare a suitable poison for the time being, but after thinking about it carefully, he felt that it was not bad to experiment with a cross-meat man and a monkey, anyway, his blood could detoxify, so he didn't have to worry that this poison pill would poison the two of them.

He checked the state of the monkey and the cross-meat man, and found that their wounds had almost healed, and now even if he fed them poison directly, it would not prevent them from recovering.
