"It's incredible, and if I hadn't seen it myself, I couldn't believe that I could make a spirit guide from these things alone. ”

Du Fei said in amazement.

At this time, Ye Ning was carefully collecting the refined toxins.

Luckily, there are small closed containers that you can carry with you, which were originally just for a rainy day, but now they are just right for use.

"The principle of the spirit guide, simply put, is to construct a unique material form change through the theory of structure and materials, and under the stimulation of spiritual power, some effects beyond the reach of human beings can be achieved. In this case, with the support of the same structure, the material often has a certain degree of substitutability. ”

While Ye Ning carefully collected, he continued to patiently explain: "Of course, this kind of alternative standard has great limitations, at present, almost only the basic-level spirit guide can be replaced with limited resources in emergency situations, and this replacement often needs to pay the price of the performance of the spirit guide. ”

"Has the performance of your spirit guide deteriorated? Looks ...... It seems to be fine. ”

Du Fei asked very clearly.

Lin Chuxia also looked curious, although Tang Chu's face was still expressionless and indifferent, his eyes were obviously loose.

"The performance of this spirit guide has not decreased much, and it has not exceeded five percentage points in the sky, but the problem of materials is more obvious after all, so there is a big gap between the durability and the real spirit guide, and it is easy to scrap it. In order to extract all the toxins from these hundred or so scavenging dogs, I would have to make at least three of these spirit guides improvise. ”

Ye Ning continued to be busy with his own affairs, and replied without raising his head.

At this time, it was already night, although the starlight in the sky was still brilliant, but after all, it was in the dense forest, and the brightness around it was far from being comparable to the day, and the influence of objective conditions caused great trouble to Ye Ning.

He had to be more careful in the process of making spirit guides and extracting toxins.

"Actually, 1,300 years ago, when the spirit guide was first born, the materials used to make the spirit guide at that time are these similar things that I am using now. In that barbaric era, the spirit guide was not systematic, without any theoretical support, and only relying on Li Xingzhou's own continuous research and testing, the materials that could be used for the production of the spirit guide were of course very primitive. ”

Ye Ning continued to popularize the knowledge related to spirit guides to Du Fei and the others.

Although they rarely came into contact with this kind of thing, Du Fei and the three of them listened with great interest.

After all...... This is something that has changed the entire form of human society! It is considered to be a landmark creation in human history!

And this knowledge, in fact, no one has ever told Ye Ning, Zhuang Bieli only taught Ye Ning the most widely used basic refining science, as for those materials that are like literature, there is no mention of them at all.

The reason why Ye Ning knew this was completely because after his basic refining proficiency reached 100 percent, the Immortal Spirit Cultivation Manual was directly instilled into him.

"Li Xingzhou has spent his whole life just making basic-level spirit guides. The pioneering road of the pioneers is always full of ups and downs and difficulties. Because in the beginning, people did not have the concept of so-called originals, and the source of materials was too primitive, which also limited the emergence of higher-grade spirit guides. ”

"High-grade spirit guides have to be made from stronger, more compliant originals, and the original materials need to be further polished to meet the requirements. In this way, a discipline relying on spiritual guides came into being, which is materials science. ”

"Strictly speaking, the history of the development of spiritual guides is actually the history of the development of materials science. For 1,300 years, future generations have continued to stand on the shoulders of their predecessors, and while designing more powerful spirit guides, they must also have better materials to make these spirit guides. ”

Li Xingzhou created a new era, but what really made this era shine was the countless sages who were immersed in the study of spiritual guides and materials science in the following 1,300 years. ”

Ye Ning soothed the three of them about the history of the development of the spirit guide, and at the same time finally completed the extraction of all the toxins from more than 100 scavenging dogs!

It was only about five milliliters, but according to Ye Ning's estimate, this dose of toxin was enough to poison a trainee spiritual cultivator to death!

Under normal circumstances, the toxins contained in the fangs of scavenging dogs would not pose any threat to the trainee spiritualists who had already activated the immortals in their bodies.

But the five milliliters of toxin refined by Ye Ning are the essence of the essence!

The most terrifying part of the toxin that retains the fangs of the scavenging dog!

All condensed together, the toxicity is so intense that it is far from being comparable to normal conditions!

"If it's not age, it's impossible to fake...... If your appearance matches your age very well, I really wonder if you are already in your thirties or forties. How could a student who was just in his third year of high school have such a deep understanding of alchemy?"

Du Fei looked at Ye Ning with admiration, couldn't help but shake his head, and continued: "Although I have also heard that some masters can use local materials, replace them with unpolished raw materials, and temporarily make or repair spirit guides, and there are even special institutions in the army to study this field, but to be honest, today is the first time I have seen it, and there are really people who can do it." ”

"Age doesn't tell the whole story, you and Tang Shu are very typical examples. As for me...... It's just more special than the two of you. ”

Ye Ning smiled and stuffed the container containing the toxin into his personal pocket.

Because it was too late, the four decided that the carcasses of the more than 100 scavenging dogs would be taken to the temporary camp tomorrow to redeem points.

In this way, how to store it tonight becomes a problem.

After a brief discussion, in order to avoid accidents, the four of them still spared no effort to hang all the corpses of these scavenging dogs on the fork of this ancient tree.

After finally finishing his work, Ye Ning was ready to rest, but Du Fei suddenly thought of something, and said with a smile: "Speaking of which, when Tang Shu and I were active in this place of bones before, we heard some rumors about the place where bones were buried. Some people say that there seems to be a tunnel in the place where the bones are buried that can be directly connected to Canglan City, and I don't know whether it's true or not. This month, if you have free time, you can try to find it. ”

"Authentically?"

Ye Ning repeated in surprise.

"It's just a rumor, before the founding of the empire, the location of Canglan City belonged to the capital of another small country, so it is said that there is a hidden secret passage, and it is rumored that there is still a wealth left by the royal family of that small country in the secret passage, of course, I personally prefer that this is just a trick made up. ”

Du Fei shrugged his shoulders, obviously feeling a little ridiculous about this rumor.

Ye Ning nodded and didn't ask any more.
