The principle of Nechadan has been directly analyzed by Yang Chen with his detailed pharmacological knowledge. Which medicinal materials and ingredients will cause the effect of expanding the sensation, which kind of sensation is amplified, and how to specifically eliminate pain. The original Nechadan

How many of them were side effects that were not expected from the medicine, etc. After Yang Chen re-analyzed the prescription, he understood clearly.

Of course, this is just a theoretical understanding. If you want to verify it, you still need to refine it to know the specific effect.

Whether it is Necha Dan or the improved Necha Dan, it has never been too difficult for Yang Chen. It is just a test, so Yang Chen does not need to directly go to the level of eighth-level refining. In fact, in the past, Yang Chen carefully

After one round of refining, the efficacy of the medicine may not be worse than that of six rounds of refining. As of now, it is only stronger.

Hearing and pain are the main troubles that cause fainting and pain to users, so Yang Chen wanted to first test the effect by removing the drugs that enhance these two feelings.

Different from refining alchemy in the past, Yang Chen used to make alchemy when he felt that he wanted to, as long as he found a safe enough place. But now Yang Chen seems to be more particular about it. Not only must he be among the most professional alchemists of Dragon Palace, he must also

Adjust your body and mind first and let your condition reach its peak before taking action.

This is a change in attitude towards alchemy. Alchemy is a knowledge that is more profound than spiritual practice and must not be treated with a casual attitude.

After thinking through all the details in his mind, Yang Chen started to take action. If anyone was watching, as soon as the fire came out, they would immediately be able to see the difference between Yang Chen's alchemy now and before, and the difference from most alchemists.

.

Ordinary alchemists are only proficient in one or several kinds of fire, but there must be only one kind that can become the natal fire. The same goes for Yang Chen, there is only one natal fire. But his Yin Yang Burning Sky Fire can simulate any fire in the world.

Usually when an alchemist receives a pill recipe, he or she will use his or her own natal fire to refine the pill, unless it is similar to Yang Chen's invention of the amputated limb regeneration pill, which has strict requirements for the fire to temper the medicinal materials. Most ordinary pill recipes

, there is no special requirement for fire.

Yang Chen directly simulated dozens of types of fire. Each medicinal material was first refined and purified according to the fire type and processing method that was most suitable for the pharmacological effect of the medicinal material. This step alone made more than 99% of the fire

The alchemist was intimidated.

This is only the preliminary preparation work. When it comes to refining, it is another amazing scene. Dozens of the most suitable fire types actually appear in the alchemy furnace at the same time, and each medicinal material and other medicinal materials

When fused, it works properly, and everything seems so natural and harmonious. It seems as if it is exactly how it should be.

After completing the elixir and collecting the elixir, Yang Chen could sit up and move smoothly, full of rhythmic beauty, so relaxed and free, without any difficulty at all.

Ten round pills appeared in Yang Chen's hand. They looked ordinary and inconspicuous. Yang Chen didn't care, then picked up one and threw it into his mouth. He sat on the ground and closed his eyes to feel the effects of the medicine.

As Yang Chen expected, after removing the sense of hearing and pain, this elixir, which is comparable to the seven-turn Neicha Dan, still amplifies other feelings to the extreme. Without pain, you can feel the feeling of surging like a river in your body.

The blood flow, the rhythm of the muscles in the body, the friction of the bones and joints. Everything is so clear.

The success of an experiment shows the correctness of Yang Chen's thinking method. However, it is not perfect at this point. What Yang Chen wants is not just this ordinary perception, but to understand all kinds of trivial details in the body.

It is not enough to fully understand the wound. Therefore, this step is not enough.

The improved Nechadan still had flaws. There were still areas that could be improved. When the furnace was turned on again, Yang Chen made some more improvements. This time, he removed the external touch and the enhancement of sight, smell, and taste, and purely

All that remains is the sense of touch in the body.

The elixir was still as successful as the instant release. However, there is a slight difference. This time, the elixir was not an elixir, but a powder. The powdered medicine can no longer be called Necha Dan, but Necha Powder.

If other alchemists saw this scene, they would definitely find it unbelievable. A dignified eighth-grade alchemist actually did not refine the elixir, but instead refined a bunch of pills. This is simply an embarrassment to the alchemist!

But Yang Chen doesn't think so. Whether it's a pill or a powder, the form is not important. What's important is the effect it can achieve. In fact, Yang Chen already understood this when he became a seventh-level alchemist.

Logically speaking, the only purpose of refining high-transformation elixirs is to increase the confidence of those who take the medicine.

And at a higher level, the alchemist himself gives the monks the greatest confidence. As for whether the refined medicine is a pill, a powder, or a decoction, what is the difference?

Just like a master who has reached a certain level, the purpose of killing is to kill, so what is the difference between killing with a sword, killing with a knife or killing with your hands?

After taking Neicha Powder, Yang Chen felt different again. This time there was no external interference at all, leaving only the pure feeling in the body. Compared with the improved Neicha Powder just now, it was indeed a step forward. Basically,

Yang Chen could already feel the subtle injuries in his body, but it was just not clear enough.

For Yang Chen, this was still a bit dissatisfying, and there was still room for improvement. After carefully thinking about why it didn't feel clear enough and the interfering factors, Yang Chen started refining it again.

This time it was even more extreme. What was refined was a liquid instead of a solid. These almost transparent and colorless liquids were carefully received by Yang Chen into the jade bottle, and then he began to experiment.

Surprisingly, Yang Chen didn't even drink the medicine directly by mouth this time, but injected the decoction directly into his blood vessels.

In the eyes of ordinary alchemists, this is an absolutely deviant approach, and they will even hate it deeply. This definitely lowers the alchemist's style, and is completely a step back, reducing the noble alchemist to a low-level physician in the mortal world.

Which state is tolerable and which is intolerable?

Yang Chen previously analyzed that what slightly interferes with his feelings should be the impact of stomach absorption after taking the medicine. After all, it has to pass through the digestive system, which increases the pollution of various body fluids such as gastric juice and intestinal juice. The lack of pure effect of the medicine is also the reason.

Injecting directly into blood vessels avoids unnecessary contamination and fully delivers the medicinal solution to all parts of the body. The effect is absolutely direct and effective.

The fact is just as Yang Chen expected, this time, he got satisfactory results. (Want to know more exciting news about "Slaying Immortals"? Open WeChat now, click on the "+" sign in the upper right corner, and select Add Friends to add public
