"It's incredible. If I hadn't witnessed it with my own eyes, I would have really hard to believe that just through these things, I could make a spiritual guide."

Du Fei said in amazement.

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

Fortunately, there is a small enclosed container that I carry with me. It was originally just for emergency purposes, but now it is just in use.

"The principle of a spiritual guide, simply put, is to construct a unique material form change through the theory of structure and material, and under the stimulation of spiritual power, some effects that human power cannot achieve. In this case, with the support of the same structure, materials often have certain substitutability."

While Ye Ning carefully collected it, he continued to patiently explain: "Of course, this substitutable standard has great limitations. At present, only basic-level spiritual guides can replace limited resources in emergency situations, and this replacement often requires the cost of degradation of the performance of the spiritual guide."

"Have your spiritual guide reduced performance? It looks...it seems to be fine."

Du Fei asked without much clarity.

Lin Chuxia was also curious. Although Tang Zhan was still indifferent and expressionless, his eyes were obviously loose.

"The performance of this spiritual guide has not been reduced much, and it has not exceeded five percentage points in the sky. However, the material problem is more obvious after all, so the durability is quite different from that of the real spiritual guide, and it is easy to be scrapped. If you want to extract all the toxins of these more than 100 rotten dogs, I have to temporarily make three such spiritual guides."

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

It was already night at this time. Although the stars in the sky were still brilliant, they were in the dense forest after all, and the brightness around them was far from comparable to that during the day. The influence of objective conditions caused great trouble to Ye Ning.

He had to be more careful in making spiritual guides and extracting toxins.

"In fact, when the spiritual guide was first born, the materials used to make spiritual guides were the similar things I am using now. In that wilderness era, spiritual guides were not systematic and had no theoretical support. It was only through Li Xingzhou's own continuous research and testing. The materials that can be used for spiritual guides were of course very primitive."

Ye Ning continued to popularize knowledge about spiritual guides to Du Fei and the other two.

Although he rarely comes into contact with this, Du Fei and the other two were very interested in listening.

After all... this is something that has changed the entire human society! It is considered a milestone creation in human history!

In fact, no one has ever told Ye Ning about this knowledge. Zhuang Bieli only taught Ye Ning the most widely used basic weapon refining science. As for the materials that are just like literature, there has been no mention of them at all.

The reason why Ye Ning knew about this was that after his basic skill in refining reached 100%, the Fairy Spirit Development Manual was directly infused to him.

"Li Xingzhou was actually just making basic-level spiritual guides in his life. The pioneer's pioneering path was always full of ups and downs. Because at the beginning, people did not have the concept of so-called originals, and the source of the materials was too primitive, which restricted the appearance of higher-grade spiritual guides."

"High-grade spiritual guides must be made of stronger and more standard-compliant originals, and the original materials need further polishing and processing to meet the requirements. In this way, a discipline based 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, later generations have been constantly standing on the shoulders of their predecessors and designing more powerful spiritual guides, and they also have better materials to make these spiritual guides."

"Li Xingzhou created a new era, but what really made this era shine completely was the countless sages who were continuously immersed in the research of spiritual guides and materials science in the next thousand three hundred years."

Ye Ning soothed to the three of them about the history of the development of spiritual guides, and finally completed the extraction of all 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 an intern spiritual practitioner to death!

Under normal circumstances, the toxins contained in the fangs of the rotten dog are not a threat to the intern spiritual practitioners who have activated the fairy spirits in their bodies.

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

The most terrible part of the toxins of the scavenged dog's fangs is preserved!

All concentrated together, the toxicity is far beyond the normal situation!

"If it weren't for age, it wouldn't be faked... Your appearance is very consistent with your age, I really have to doubt whether you are already in your thirties or forties. How could a student who just had a senior high school degree have such a deep understanding of weapon refining?"

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

"Age does not explain the whole issue. You and Tang Zhan are very typical examples. As for me... I can only say that they are more special than you two."

Ye Ning smiled and stuffed the container containing the toxins into his close-fitting pocket.

Because it was too late, the four decided to take the bodies of more than 100 scavenging dogs to redeem points tomorrow.

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

After a brief discussion, in order to avoid accidents, the four of them hang all the corpses of these scavengers on the fork of this ancient tree without any effort.

Finally, Ye Ning was about to rest, but Du Fei suddenly thought of something and said with a smile: "Talk, Tang Zhan and I were active in this bone burial place before, and we heard some rumors about the bone burial place. Some people say that there seems to be a tunnel that can directly connect to Canglan City in the bone burial place, and we don't know whether it is true or not. If you have free time this month, you can try to find it."

"typical?"

Ye Ning repeated it in surprise.

"It's just a rumor. Before the founding of the Empire, Canglan City was located in the capital of another small country, so it is said that there are hidden secret passages, and there are still wealth left by the royal family of that small country. Of course, I personally prefer that this is just a trick made up."

Du Fei shrugged, obviously feeling a bit absurd about this rumor.
Chapter completed!
