"Dead old man, throw me the difficult ones again!" Zhang Zhongjian smiled bitterly and said helplessly: "Senior Brother Lin, I think Senior Sister has already told you, the impact of negative abilities on people. ”

"I said it," Lin Yufei nodded.

"Then I'll tell you another point, I guess Senior Sister doesn't know either, after all, she hasn't cared much about other things besides cultivation. Zhang Zhongjian hesitated for a moment before saying: "I don't know if it's accidental or inevitable, the Taoist techniques we cultivate, Western alchemy, magic, and other strange arts, most of them will be related to a certain kind of conceptual ability after reaching the extreme." Once there is a connection, then the cultivation of this technique will be very easy to stimulate the concept of association. After the wind technique reaches the conceptual level, the easiest thing to stimulate is destruction!"

Lin Yufei couldn't help but be stunned, stunned and speechless. In fact, since Xin Lan told him about the impact of the power of destruction, he has basically accepted this result in his heart, so even if Zhang Zhongjian told him this, it actually didn't touch him much. It's like someone tells him that you will definitely die, the difference is only between dying today and dying tomorrow, what can be the difference? What really makes him dazed is Yun Huan's performance. After Xinlan told him Yun Huan's thoughts, he actually had some resentment before going out, and he practiced hard and waited for fifteen years, thinking that he would be much happier when the teacher came back, but who expected that he would be a blow to the head. He is a person who easily compromises with reality, especially after knowing that the teacher actually has nothing to do, the resentment basically disappears. But looking at Yun Huan's performance just now, there was a warm current in his heart - it turned out that the teacher still cared about him.

There was a sudden silence in the bedroom. Lin Yufei didn't speak, Yun was still there in a daze, and the other three all looked at Lin Yufei with concern, and even Xinlan had a trace of concern in her eyes. In the end, Ye Fei couldn't help it, and quietly stabbed Lin Yufei: "Senior brother, are you okay?"

Lin Yufei came back to his senses: "I'm fine, don't worry." Xiang Yun replied: "Teacher, don't worry, I've figured it out, since the outcome of the matter can't be changed, it's better to accept it calmly, if you don't have it, there will be unexpected surprises." ”

"Just look at it. Yun Huan's face finally softened, he clenched his fists tightly, and finally made up his mind, "Okay, just like you said, if you can't change it, just accept it." In view of your loss of control yesterday, I will give you two days to relax and start to concentrate on cultivation tomorrow, and I also have a few secret methods to teach you. We won't call you until tomorrow night, as long as there is nothing particularly urgent. ”

"Yes, teacher. ”

"OK! Although I don't know what's going on yet, it's okay to be fine!" Ye Fei finally breathed a sigh of relief, clapped his hands and smiled, "Now that the matter of the second senior brother is settled, let's all go out, and I also brought some good things." ”

"Then you'll have to take a closer look. Yun also narrowed his eyes and smiled slightly. The knot in his heart was finally untied, the haze that had accumulated in his heart for two days was finally cleared, and his mood finally improved.

When he came to the living room, Lin Yufei found that Ge Tongshan was meditating in the living room, and when everyone came out, they were collecting their work, and when they saw everyone coming out, they looked at it coldly, and only locked on Lin Yufei. Lin Yufei felt uneasy again, and when he saw Ge Tongshan open his eyes, he had to step forward and say, "Mr. Ge, I'm really sorry for what happened last night." Are your injuries getting better?"

"It's just a little out of strength, don't underestimate me!" Ge Tongshan snorted softly, "Some people in yesterday's fight were messed up, wait until you can control it, and then fight with me!"

Lin Yufei listened in a daze. The dissatisfaction of this guy is just because the competition was disturbed. Zhang Zhongjian stepped forward and patted this junior brother on the shoulder, and said with a smile: "Senior Brother Lin, you don't need to worry about how injured this guy is, I guess this kid is not seriously injured!"

Ge Tongshan snorted: "If you don't get hurt, you will make progress?" Boy, your last two moves yesterday, I don't look like wind techniques, you used water techniques, right?"

"Water technique?" Before Lin Yufei could answer, Ye Fei had already shouted on the side, "Another kind! Second Senior Brother, you leave someone a way to live!"

"It's not a water technique, I haven't practiced a water technique yet," Lin Yufei was embarrassed, and comforted Ye Fei by the way, "But it's really a water bomb, it's a water drop collected from the air with wind magic, and then strengthened with wind and thunder." ”

"It's not that simple, right?" Zhang Zhongjian showed a puzzled look on his face, "Even if it's a drop of water, how much weight can that little drop of water have?

"It's just that the speed of the flight is slow," Lin Yufei had no choice but to explain, "In fact, it has been strengthened in the storm field, allowing the water droplets to carry out a very small range of centrifugal movements in the shell wrapped in the wind technique—oh, just like the meteor hammer that has been wielding the charge but not throwing it out, the thunder and wind techniques are mainly used to strengthen the centrifugal movement, so what you see is just the shell formed by the dense wind technique, and the real power of the flowing fireflies and mayflies can only be exerted after the shell is broken." ”

"Then how fast is this rotation, even the Dinghai stick can bounce off. Ye Fei muttered a few words in a low voice, and suddenly reacted: "By the way, why is the topic flying again, the second senior brother's moves have been explained clearly, I'll let you see my invention." Senior brother, give it!" said and picked up a box more than two meters long from the ground, which looked very heavy, Ye Fei picked up Zhenqi before picking it up, and then threw it to Zhang Zhongjian. Only then did everyone realize that there were several boxes of various sizes on the ground next to the sofa, and Ye Fei was the longest one of them.

Zhang Zhongjian was still reminiscing about Lin Yufei's previous explanation - although he had some understanding of this era, centrifugal force was obviously still a new word to him, and when he saw something flying over, he subconsciously reached out to catch it. Then I only felt a sudden sinking in my arms, and I reacted immediately, and took a step back before standing still with the pile.

"What's it, so heavy?" Zhang Zhongjian asked suspiciously, opening the box, and then he was startled. In the box is a big knife, looking at the system is a ghost head knife, but the length is close to two meters, the handle of the knife is one foot, the rest is all the knife body, the width of the knife body is more than one foot; the thickness of the back of the knife is half a foot, the head of the knife is a very fantastic round head, the blade has been received on the back of the knife, and the sharp hook is two or three inches long. This is not the most critical, the most critical thing is the weight, with Zhang Zhongjian's strength, he feels a little difficult. Ge Tongshan looked curious, opened his mouth and said, "I'll take a look." Reaching out and taking the knife in his hand, he couldn't help but be surprised with the strength he was accustomed to using the Dinghai stick: "I'm afraid this knife doesn't weigh 3,000 catties, it's heavier than gold." ”

"It's not just gold, it's the one in my hand...... Platinum, I'm afraid it's not as heavy as this. Zhang Zhongjian showed an exclamation on his face, "Little junior brother, what kind of material is this? It turns out that there are such heavy things in this world?"

"Hehe, this is actually a byproduct of my experiment, and I was trying to find a material that could withstand the pressure of an overpressure engine — uh...... This is not important, the key is this material. That day, when I saw the elder brother's divine sword, I had the idea of using this, after all, its proportion is very large, reaching 26...... Oh, it's more than 30% higher than the weight of gold, I haven't named it yet, so let's call it Heavy Alloy No. 1 first. ”

Hearing the conversation between the two, everyone else except Ye Fei was also surprised. Ge Tongshan was stunned for a long time, then turned his head and glared at Ye Fei: "Stinky boy, you have spared no effort to help your senior brother, for fear that I will win him!"

Ye Fei shrank his head and laughed dryly. Zhang Zhongjian said on the side: "I think you're more excited, right?" ”

"You know me. Ge Tongshan snorted and stopped talking.

"But junior brother, it would be nice if you could give me a small piece as a medium, such a big one, I don't need it at all. Zhang Zhongjian said again.

Ye Fei smiled: "Senior brother, don't blame me for not speaking well, didn't the teacher say that our ability cannot be held permanently? With such a big sword, even if you don't have the ability in the future, you can still retain most of your strength, right?" Zhang Zhongjian's face flashed with emotion, and he didn't speak again. Ye Fei picked up another box and turned to Xinlan. He hesitated for a moment and said, "Senior sister, can I take a look at your sword?"

Xinlan didn't speak, pulled out her saber from behind her back and handed it to Ye Fei. Ye Fei took the sword and shook it, opened the box in his hand and compared, nodded, and returned the sword to Xinlan: "Almost, rest assured." As he spoke, he opened the box and took out two swords, with carved steel scabbards, just the standard of ordinary Taiji swords, the sword body is about one meter and two long, and it looks very ordinary. However, in view of the knife he took out before, everyone did not dare to underestimate these two swords. Zhang Zhongjian hesitated and asked, "Little junior brother, this is also that...... Heavy Alloy No. 1 ...... Do you?"

"This is not, but it is also a material I made, the weight is about half less than that of Alloy No. 1, but the toughness, elasticity and hardness are much stronger - the hardness is only slightly inferior to diamond, but the elasticity and toughness are nearly twice as strong as steel, and it is suitable for making swords, but unfortunately the mechanical strength is not strengthened too much, only slightly better than high manganese steel. Ye Fei said and handed both swords to Xin Lan. Xinlan took the long sword and threw it along with her own, and the three swords flew in the air together. Although Xinlan's face remained unchanged, she was obviously very satisfied, and she didn't even care what the so-called mechanical strength was.

"Senior brother, you are really a genius," Lin Yufei couldn't help but say, "Any one of these two materials can bring your father a huge income." ”

"Hey, hey. Ye Fei smiled proudly, "It's a pity that the cost of production is too high, and we can't achieve mass production, otherwise it will be developed." Don't gossip, the next thing is my most satisfying baby. ”

As he spoke, he opened the largest box on the floor, about the size of a large suitcase, revealing its contents. Everyone went up to see that there were ten things like wrist armor side by side, the length of which could cover more than half of the forearm, and there was also a small rectangular box on it, the width of the box could cover the entire wrist, and the length of the box basically covered the entire forearm, and there were three small holes the size of soybeans in the front, and the whole body shimmered with a blue-black metallic luster.

"What is this?" Zhang Zhongjian picked one up and played with it in his hand, "Is it a hidden arrow? Or is it some other hidden weapon?"

"Senior brother, this is something beyond the times!" Ye Fei's face was black, "It's not comparable to the Hidden Arrow, if you just fight for speed, it may be comparable to the Second Senior Brother's Xun Thunder God Fire Bomb." ”

"So strong?" Zhang Zhongjian tilted his head to look at the thing in his hand, and glanced at the three small holes. Lin Yufei couldn't help but say: "Senior brother, what is this thing? If you want to say that it is a gun, even the best sniper rifle has a rate of fire of about 1,000 meters per second, right? Even if I am not confident, my Xun Thor Fire Bullet must be much faster than that." ”

Ye Fei smiled proudly: "Do you remember what I said about the electromagnetic cannon?"

"Remember," Lin Yufei replied, and immediately reacted, "Is this it?"

"Second Senior Brother, I may be worse than you in cultivation, but compared to scientific research, your junior brother and I are genius-level Lalala," Ye Fei said proudly, "Second Senior Brother, have you ever played interstellar?"

"I guess I've played it. Lin Yufei replied.

"Then you should know the Gauss rifle inside, right?" Ye Fei said, "I named this thing the Thor crossbow, and the principle is the same as that Gauss rifle, I don't know what the speed of that thing is, at least the projectile velocity of my thing is about the same as the speed of the traditional electromagnetic railgun, it should be about 4 kilometers per second." The material of the projectile is the same as the ghost head knife of the elder brother, because the density is large enough, so it can be very small, only the size of the BB bullet, but the kinetic energy is definitely not small. ”

"Plaything is demoralized!" Yun also suddenly snorted heavily, "Compared to these, you should cultivate more diligently, this kind of thing outside the body, we people probably only need you!"

"You can't say that, teacher!" Ye Fei's eyes widened, "I made this for emergency use, no matter how high your cultivation is, no matter how small the consumption is, there will always be a time when the True Qi is insufficient, even if I can't destroy the alien beast, at least there is no problem in delaying time." ”

Yun Huan's face was still ugly, and Zhang Zhongjian said in a round game: "Little junior brother, I don't think it's as good as this, how about you let the teacher see the power of this thing?"

"Okay, it just so happens that I have other things I want to see," Ye Fei agreed, while already closing the box, by the way, he looked at Yun Huan's face, and seeing that there was no refusal, he also took another electronic instrument on the ground in his hand.

"Is this also a weapon?" Ge Tongshan asked from the side.

"Why do I feel like a speedometer?" Lin Yufei wondered.

"Well, it's a laser velocimeter, but I've modified it, and the accuracy and measurable range are much higher. Ye Fei had already dragged the box to the door, "Let's go out and talk." ”
