"Stone, this mission is very dangerous." Nephrite looked at Bai Chen solemnly and seriously.

"Oh, is that?"

"Sister Nephrite, Mr. Shi once entered the depths alone." Lu Menqing said.

"The depth you are talking about is the area where mutants gather." Nephrite glanced at the three of them: "It is not a deep area. There will be transformed demon bodies in the real deep area. Only the area where mutants appear will lava crystals appear."

"Is that lava crystal hard to find?"

"It's simple to say, and it's difficult to say." said Nephrite: "In fact, a team once discovered lava crystal mines in the deep areas of the Black Death. Of course, we can't have such fantasy. It's good to find scattered lava crystals."

"So are there any tricks to find lava crystals?"

"There is a way. Lava crystals are usually hidden under lava stones. However, phantom beasts with sensitive sense of smell can smell the smell of lava crystals. But there is another thing to note that once the lava crystal is unearthed, it will immediately attract all the surrounding demon corpses to approach, whether it is a low-level infected body, a mutant, or a transformed demon body."

"Who do you have a phantom beast with a sensitive sense of smell?" Bai Chen asked.

"My three phantom beasts are all water-based phantom beasts, and they are not suitable for summoning in that kind of hot environment." said Nephrite.

"I have it, my phantom beast is a rotten face beast." Lu Menhou said.

The rotten face beast is considered a relatively alternative phantom beast. They belong to the rotten food category, but their sense of smell is much sharper than that of ordinary phantom beasts.

"Okay, the important task of finding lava crystals is to you. In terms of safety, I will leave it to me and Shi Tou and Shi Tou. We will set off tomorrow afternoon. Before that, you need to go to the library and find the right material formula, and you will not be required to find the most suitable one. At least you must increase your combat effectiveness by one level."

Bai Chen thought for a while, then nodded.

"There is also the most important thing, we have to prepare some corpse oil."

"Corpse oil?"

"Yes, corpse oil is actually a special oil extracted from the eyes of infected bodies and mutants. If you apply corpse oil to your body, you can deceive the mutants and infected bodies and make them mistakenly think they are the same."

"This thing is convenient, but will it leave any strange smell when touched on it?"

"No, we humans cannot smell the smell of corpse oil. Only demon corpses can distinguish this smell. However, corpse oil also has its shortcomings and will evaporate over time."

As the captain, Nephrite has explained the assignment and preparation of tasks very well.

Nephrite thought for a while: "I'll find a way to get more maps of the Black Death."

"Is there a map of the Black Death?" Bai Chen asked curiously.

"After some teams or mentors enter the Black Death Land, they will record the regional routes they have been to based on the locations they have been to, but most of the routes are repeated. Find a few more maps and combine them together to create a safer early route."

Lu Menhou and Lu Menqing also have this kind of map. Although the map they recorded was shorter, they did their best.

Bai Chen went directly to the library. In the Fantasy Academy, any public facilities and paid areas are not closed, such as the library.

You need 10 points to enter the library, and you need 10 points to borrow ordinary books.

With the amount of books in this library, the points required will be astronomical.

According to the guidance of the library administrator, Bai Chen found the material formula area.

After entering the material formula area, each book is marked with the borrowed price.

As much as 50 points, as many as hundreds, or even thousands. The further you go, the higher the price. Bai Chen hasn't left one-third of the bookshelf, and the price is no longer what he can afford.

Based on his own understanding, Bai Chen found a few cheaper material recipes.

Open the first book, "Material Formula-Omaruki".

Onuma wood grows in the Everglades and rarely grows in other areas.

Onuma wood is hard, but it is very easy to burn, and is not suitable for the transformation of fire-attributed illusion beasts.

The most suitable one is water, soil-attributed illusion beasts, which can appropriately increase the toughness of Onuma wood.

Next is the equation of material formula, and this equation is very special. It belongs to the annotation method of this world. Even Bai Chen can find it difficult to read it.

Through the structure of mental power, the decomposed illusion beasts are then arranged in material form.

Bai Chen summoned the flying rat and began to try to arrange matters.

Bai Chen knew that all things in the world were arranged from the microscopic angles of molecules and atoms, and this world was very special about the material structure.

People in this world think that any substance in this world can be simulated through the illusion beast materialization, and they have indeed cracked many material formulas.

Of course, there are all kinds of strange things in the world, not just hundreds of millions of them, and many two or more substances will be recombined, and new substances will be produced.

The material formulas included in the Fantasy Beast Academy cannot be comprehensive, and can only be one percent or even one thousandth of them.

Bai Chen completed the stacking of Onuma wood's material structure, but Bai Chen also discovered the problem.

The illusionized beast transformation carried out by the body of the flying rat cannot highlight the advantages of Onuma wood.

Originally, the advantage of Onuma wood was its hardness, but after Bai Chen transformed into a magic beast, the hardness of the wood was harder than ordinary wood.

Obviously, the flying squirrel is not suitable for the material structure of Onuma wood.

The material formula can be compared to the architectural engineering drawings of a building, and the fantasy beast itself is the building material.

No matter how clever the construction drawings are, if they are constructed with tofu materials, they will be useless except to create a disaster building.

Bai Chen began to open the second substance formula again, "Material formula-Bai Tie".

Bai Chen not only studies the advantages and disadvantages of these materials themselves, but also analyzes their practicality, as well as the compatibility of the flying squirrel.

The Jikong Feishe is too weak, so it does not have a good fit for most advanced materials.

At this time, the librarian came over and said, "Your name is Shi Tou, right?"

"Well, what's wrong?"

"I just kept watching you conduct qualitative experiments on your phantom beast. You have a lot of mental power. Are you really only six years old?"

"Is there any problem?" Bai Chen looked up at the librarian.

"I just want to share my experience with you. I have worked in this library for two years and have seen a lot of material recipes. However, I don't have much opportunity to communicate on weekdays. The mentors or senior students look down on me and don't want to communicate with me. I don't want to communicate with ordinary students. I think you are a suitable candidate."

Bai Chen smiled. This librarian had an embarrassing position. Because of his position, his vision was not low, but his strength did not keep up, resulting in the fact that he could not make a difference. What he lacked the most was communication with others.

"What kind of material formula do you think is suitable for my phantom beast?"

"Your phantom beast is too weak. Is this a flying squirrel?"

"It's a flying squirrel."

"Jikong Flying Squirrel, a good thing... Unfortunately, it is still too weak now. It is no different from ordinary Flying Squirrels now, and its early evolution speed is definitely not slow. When you master the most suitable material structure, it is probably already evolved. At that time, it needs to find the material formula again. This is very stupid behavior. So my suggestion is that you give up finding the material formula that is suitable for it now, and instead study its evolution after evolution, as well as the material formula, or even two or three times."

"The strength of the phantom beast has increased. Will it also require material formulas again?"

"Of course, don't you know?"

"I'm just now in touch with the magic beast's essence and am relatively unfamiliar with this aspect." Bai Chen was a little depressed. It seemed that Dong Ao had forgotten to tell him about this. Or he did it on purpose.

"So how can I determine what material structure the evolutionary phantom beast is suitable for?"

"This requires more complex research, as well as the strength positioning of the illusion beast after its evolution. There are always such records in some documents, or when the predecessors had the flying squirrel, what type of material structures were used at each level could be used as reference objects."

"Yeah. Thank you."

"I've explained so much to you, but I actually have my own demands."

"Oh, what do you want to ask me?"

"Your mental power is so abundant, is it the result of your own practice? Or is there any special way?"

Bai Chen thought about it, but the library administrator was not in a hurry to ask, but was waiting for Bai Chen's answer.

"The mental meditation used by most people is actually flawed, and mental power is actually generated through body energy. Ordinary meditation is very inefficient for this energy to convert mental power."

I have to say that the various meditations in this world did not make Bai Chen’s eyes lit up.

Although this world has a unique fantasy beast civilization, it still has some shortcomings, such as meditation and the improved mental efficiency are really too low.

Bai Chen and Jixu said: "In fact, the most effective way to improve mental power is to consume, not meditate."

"Meditation is to actively transform body energy. Due to the defects of meditation, only one-tenth of the energy of one hundred may be converted into mental power. However, by consuming a lot of mental power, it is the body's instinct to transform mental power to fill mental power loss. The efficiency is far higher than the efficiency of meditation. However, higher mental power can be obtained through consumption. One of the problems is fatigue, very fatigue and pain. If you cannot master the appropriate degree, then you will also lose your life while improving your mental power."

"Can your mental power be improved by this way of consumption?"

"That's right." Bai Chen replied.
