After the brain domain is developed by the superpower, each brain computing ability is comparable to that of the previous generation of optical brains. Almost every superpower knows how to design corresponding skill formulas based on their superpowers, except for someone.

However, the design of skill formulas is different from real combat after all. It does not mean that a person has strong strength, the designed skill formulas must be strong, nor does it mean that a person has weak strength, the designed skill formulas must be weak. Superpowered skill design is also related to imagination to some extent, which varies from person to person.

Therefore, a special group, skill designer, appeared in the City of Science and the affiliated islands. This group of people has uneven strengths, including high-level superpowers and first-level low-level superpowers. However, they all have one thing in common, which is that they have the talent for design skills. Some strong people who reach the level of high-level will often ask them to help design skills.

It happened that Su Yu was absorbed into the Skill Design Association of Island No. 8 because of his time superpowers. Of course, the reason was not that Su Yu had extraordinary talent in this regard, but because the group of skill designers were competitive.

The reason was that they heard about Su Yu's time superpowers, just to be too curious to see. Unexpectedly, after seeing him, they found that Su Yu's ability was extremely domineering, almost completely defeating all superpowers. At this time, some designer had the idea to design a skill to counter Su Yu's superpowers. In this way, Su Yu joined this association as an opponent in every skill test.

Of course, joining the association is not without benefits. At least Su Yu often sees some strange skills and some books about skill design that cannot be found outside. And you can also observe the process of skill designers' design skills, which makes Su Yu improve rapidly in the design ability of skill formulas.

However, this is all the past. Su Yu has not been looking for these guys during this period. However, facing Zhan Nan, who had never designed the skill formula, Su Yu took the initiative to take on this task.

After hearing this, Zhan Nan said, "My ability is actually nothing special. It is to force gaseous nitrogen to liquid nitrogen in a short period of time."

Su Yu nodded gently and said, "Then how long does this take?"

Zhan Nan tilted his head and thought for a while, "It will take about ten seconds."

Su Yu touched his chin and said, "Liquid nitrogen had appeared three hundred years ago. The danger of this kind of thing to the human body mainly comes from its rapid absorption of heat from the surrounding air when the liquid state turns into gaseous state, causing a freezing effect."

Zhan Nan nodded constantly and said, "Yes, I just used this method to attack, but it only works for people who are not wearing anti-cold clothes. Others like mechas are not very threatening."

Su Yu shook his head and said, "The usage is too rough." After a pause, Su Yu continued, "In addition to the freezing effect, liquid nitrogen can reduce the oxygen partial pressure of the air during gasification, causing a suffocation effect."

Zhan Nan heard this and said in surprise: "Can it still cause a suffocation effect?"

Su Yu rolled his eyes and said, "Damn! Don't you know it yourself?"

Zhan Nan scratched his head with a wry smile and said, "Actually, I have never used this superpower in reality. The main reason is that it has a large impact range and may die if it is accidentally killed. Therefore, it is usually used on virtual battle networks, and the opponents are basically frozen to death." After pausing, Zhan Nan touched his nose and said, "But even with the suffocation effect, it seems that it is more lethal to people without any protection. If you drive a mecha, the impact does not seem to be too great."

Su Yu shrugged helplessly and said, "There is no way to do this. The development of the mecha is originally intended to deal with the superpowers. Except for some superpowers with strong explosive power, other auxiliary superpowers cannot break the defense of the mecha." Speaking of this, Su Yu changed his mind and said, "However, there is no regulation that the superpowers cannot use weapons." After saying this, Su Yu showed a confident smile on his face.

"Use a weapon?" Zhan Nan showed a puzzled expression when he heard this.

Su Yu ignored him and asked, "Just just inject your ability into the air, and then in ten seconds that part of the nitrogen will be converted into liquid nitrogen?"

Zhan Nan nodded instinctively and said, "Yes!"

Su Yu snapped his fingers and said, "I have thought of it!" As he said that, Su Yu pulled open the exchange panel, glanced at it a few times before choosing a spear.

Zhan Nan saw the spear that suddenly appeared in Su Yu's hand and said even more puzzled: "Gun? What does using a gun have to do with my superpowers?"

Su Yu glanced at him and said, "Of course it's related. Your ability is actually not weak, especially the frozen attack, which is basically few people can withstand. However, the disadvantage of this move is still very obvious, it is that you can't hit the target far away. You only throw liquid nitrogen with your hands, how far you can go. If I didn't fight you closely, but attacked from a distance, you would definitely lose."

Zhan Nan nodded seriously and said, "Boss, you are right. On the virtual battle network, as long as the opponent attacks from a distance, I will definitely lose."

Su Yu smiled and said, "That's it."

Zhan Nan turned and smiled bitterly and pointed at the gun on Su Yu's hand and said, "Then what does this have to do with the gun?"

At this time, Su Yu finally couldn't help but knocked hard on his head and said, "Idiot, see clearly, this is not an energy gun. This is an aerodynamic gun!"

"Air Compression Gun?" Hearing this, Zhan Nan's eyes finally showed a thoughtful expression.

Su Yu continued to explain himself: "This kind of gun already existed during the live ammunition period hundreds of years ago, but it was not very powerful at that time. With the emergence of the air superpowers, their powerful attack power also triggered some ideas from people. It is whether the old-fashioned air** can launch an attack comparable to the air superpowers. After decades of improvement, the City of Science has finally developed this new air compressor. Although its power is not as powerful as that of the air superpowers, it is not comparable to that of the old-fashioned air***. This long spear has hit all the hardest and hit targets 300 meters away. Even if the opponent is a mecha, it can cause certain damage to the external armor."

Speaking of this, Su Yu handed the air compression spear in his hand to Zhan Nan, and then continued: "It takes ten seconds to start your ability. If you inject superpowers into the air bullets to be fired in advance, ten seconds is enough to make the spear hit the target, and then instantly turn into liquid nitrogen to freeze the freezing effect. For mechas, one shot may not work, but shooting a few more shots, breaking the outer armor, and then using superpower bullets to freeze the inside of the mecha, you can cause damage to the mecha. Anyway, this air compression spear consumes very little energy, and it is not a problem to hit three hundred rounds with one energy block. Together, you can make your superpowers better."

Listening to Su Yu's words, Zhan Nan also thought that he could indeed use his superpowers better after using the gun. At least, the problem of long-distance strike has been solved. Although 300 meters is not too long, it is enough at this stage. Moreover, as the ability improves, the gun can be changed. The power of the air**, coupled with the accidental superpower bullets, is enough to make everyone have a headache.

Just as Zhan Nan was constantly thinking about the bright future, Zhan Nan’s personal terminal sent a prompt to receive the message. At this time, Su Yu’s voice also rang out: “This idea is good, but it is not easy to truly exert its power. I have designed the skill formula, and there is a method to write calculations on it. You can memorize it yourself. Let me remind you again that the main difficulty of your trick lies in the calculation of time. Just practice the rest yourself, and there is still an hour left. I hope you can master it quickly.”

"I understand, boss!"

When Su Yu heard this, he stretched and said, "Okay, you practice here slowly. I'll go to the arsenal to see what weapons are there." After saying this, Su Yu used his light skills, and several ups and downs disappeared in front of Zhan Nan's eyes.
