"It's the real thing."

Xu Baiyan nodded, his voice was not loud, but because the warehouse was too quiet, it was extremely clear.

Ban Jian relaxed a lot and smiled: "Principal Xu used it a lot back then, and he can recognize it at a glance." ”

The No. 0 stock solution is so famous that almost every teacher has heard of it, but there are very few people who have seen it, and even fewer people can distinguish the real from the fake. Xu Baiyan can distinguish the authenticity at a glance, and he must have been in contact with it before.

In the 30s of the last century, a planet called the "Red Sea" was discovered. More than 90 percent of the surface of the red starfish is covered by seawater, because a red algae grows in the seawater, and the sea water has a strange red color, hence the name of the red starfish.

This red algae is named red algae.

It is the largest ever discovered by humans, with a length of more than 20 kilometers. Originally used as an ornamental algae, it had a jade-like texture.

In subsequent studies, it was found that the algae has the effect of repairing neuronal tissue. Akatama began to be used in health food and the treatment of brain damage, especially for therapists, and the effect was very obvious.

Humans began to develop and cultivate red jade algae in a deeper way.

In 3961, one of the top laboratories of the Alliance, the Baiyangling Biological Science Laboratory affiliated to the Fei's Group, announced that it had successfully developed the first gene fluid that can promote the evolution of brain neurons - [Shuguang No. 1].

Since then, the research on gene fluids has set off a climax, and other groups have invested huge sums of money to set up special laboratories.

In 3966, the Yan family, a traditional wealthy family in Beirin, appeared the first super master in human history to take gene liquid to be promoted, Yan Xiaofeng.

Half a century has passed, and the development of gene fluid to composite gene reagents has long become a ubiquitous commodity, whether it is in the teacher's association, or in the store can be bought, the most convenient is online shopping. Of course, the genetic reagents that can be bought on the market are of relatively low grade and are all ordinary goods.

High-end genetic reagents are often difficult to buy with money, and occasionally appear on the black market, and they can also be sky-high.

The extraction and refining technology of high-order genetic reagents is very complex and extremely expensive, and it is basically all in the hands of major groups. Even these large groups do not produce as much as they want, and their annual output is extremely limited, and they are strategic materials for major groups and will never be sold to the outside world.

In addition, the laboratories of the coalition government can also produce genetic reagents and provide them to the military and various departments.

If neither wants to join, the only way left is the Teachers' Association. The guild issues various tasks and commissions, and if they can be completed, they will be awarded the corresponding points. The association's points are very high in gold and can be exchanged for various resources needed by teachers and soldiers.

With fewer restrictions and access to scarce resources that are hard to buy in the market, the Guru Guild has rapidly expanded within the alliance from its inception.

Although each group produces genetic reagents and has different formulation processes, there is no difference in the most important raw material stock solution. The stock solution is an extract of mutated red jade algae, which has different labels depending on the quality.

Zero is the highest grade stock solution.

The stock solution cannot be used directly, it is extremely toxic. Even if the user does not die, it will produce genetic mutations, body aberrations, and become monsters.

The stock solution needs to be added with other drugs to dilute and eliminate toxicity, and the formulation process of each group is different, and the effect of the gene reagent produced is also very different. These unique formulas and processes are the core trade secrets of each group.

The higher the level of brain control, the higher the level of genetic reagents.

It took a lot of effort for Leng Qiu to get this No. 0 stock solution. If it is placed on the black market, it can definitely be sold for a sky-high price.

However, Xu Baiyan gave a price they couldn't refuse, a zero stock solution for five kilograms of Aurora titanium.

Zero stock solution is very rare, costly, technically cumbersome, small in production, etc., but after all, humans can produce it.

Aurora titanium, on the other hand, is a natural alloy that humans have not been able to produce so far. It can occasionally be encountered in asteroids in the universe, and has a brilliant luster like an aurora. It contains 71.3% titanium, and other components vary, and humans have not yet found the mechanism of its formation.

The biggest role of Aurora titanium is that it can receive and feedback human brainwaves. It is easy to distinguish the real from the fake, because as long as a piece of aurora titanium is placed in front of you, you can clearly perceive its existence with your eyes closed.

The higher the level of brain control, the stronger the feedback response of Aurora Titanium. Its biggest role is to be used on the light armor, becoming the neural network of the light armor, and seamlessly connecting with the teacher's brain.

With the light armor of Aurora Titanium, the master can directly feel every change in the light armor in his brain, and even the subtle deformation of the armor can be clearly perceived.

Aurora titanium is known as the "soul" of high-end light armor, so there is the light armor of Aurora Titanium, also known as soul light armor.

It is something that every teacher, even a super master, is extremely eager for.

Xu Baiyan took out five kilograms at once, and Ban Jian couldn't refuse at all. Save a little, five kilograms can even be used on two light armor.

Ban Jian didn't know where Xu Baiyan got the five kilograms of aurora titanium, maybe it was the treasure of the legendary fortress. He didn't know what Xu Baiyan wanted the No. 0 stock solution for, or if Xu Baiyan had any special formula that could use the formula of the No. 0 stock solution, did Xu Baiyan still want to restore his former strength

But that's his business! As long as he is Aurora Titanium, he has just been promoted to level 11, if he has a soul light armor, even if he faces a level 12 master, he has the strength to fight against a super master without a soul light armor.

Lin Nan didn't know when there was an extra box in his hand, he walked to Ban Jian with the box, put down the box, and then retreated.

Ban Jian couldn't wait to open the box, and inside lay a metal ingot glowing with an aurora. The most wonderful thing is that the aurora on the metal ingot is constantly changing and beautiful.

Everyone held their breath and couldn't take their eyes off it.

Ban Jian closed his eyes, and the next moment his face showed ecstasy.

That's right, it's Aurora Titanium!

He could clearly perceive the presence of Aurora Titanium.

Everyone else also closed their eyes one after another, even Yaobei Temple is no exception, this is the legendary aurora titanium!

The next moment, everyone's faces showed shock and incredulity, they had never felt anything like this, this feeling, it was amazing!

Only Xu Baiyan and Lin Nan did not close their eyes in the audience, Xu Baiyan looked at the No. 0 stock solution in his hand, and he looked very carefully and attentively.

Lin Nan looked at Xu Baiyan with a calm expression.

Xu Baiyan smiled at Lin Nan, he turned on the needle switch and pierced his arm.

Zero was injected into his body at a speed visible to the naked eye.
