(Ah, it's late today, I'm sorry.) ）

"Senior, now you can always tell me the purpose of your collection of these demon soldiers."

"Wan Rongbing, now that you are your own person, I'll show off it a little. Legend has it that the ancestor of Meishan refined a mountain-swallowing giant demon, because the power was too terrible, the ancestor of Meishan sealed it before his death, and cast the key of the seal into four weapons, all of which are demon knives with special powers. The old dream pipa heart in the hands of Yan Butterfly and the ghost bone in my hand are two of them. There are many rumors about awakening this giant demon, when the Tai Poor Army was trapped in N City, he listened to the words of the warlock of the rivers and lakes, and dug into the ground three hundred meters to find this giant demon, in order to save the situation, but the result was just a bamboo basket to draw water. There is actually only one way to awaken the giant demon, which is to refine the four demon knives scattered all over the place back into the form of a key and open its seal in the depths of Meishan. ”

"Senior, is your purpose ......?"

"That's right, I'm going to wake it up!"

One of the two people who spoke was Wan Rongbing, and the other was a young man dressed as a scholar, which looked like he came out of a costume drama. The scholar held a huge knife in his hand, a weapon that seemed to be heavy enough to break his shoulder, but he held it in his hand as easily as chopsticks. The surface of the knife was dark blue, and it seemed to be completely unbladed, like a dull iron plate, and the only thing that could be considered decoration was a skull at the end of the handle.

But the place where the two men spoke was a hell of blood, littered with horrific corpses, most of which were charred and blackened. This place has been stained with blood so that it is impossible to see the original state, but there is a horizontal plaque on the ground that reads "Casting Body and Forging Heart", which shows that this place was originally a martial arts hall...... But now, it's the scene of a murder in a tragic car.

In fact, the people in the martial arts hall were not completely dead, the old curator who had been broken half of his body was leaning against the wall, his internal organs were dragged out of the hole in his stomach, and he said with a dying breath: "Are you ...... You are Liu Mengyuan! ”

"Curator Jin is really powerful, even I know me, a 'dead man' from a hundred years ago." The scholar slammed the giant knife on the ground, "I don't hate people who practice martial arts, but 'the husband is not guilty, and he is guilty', if you want to blame this Nai He Bridge." ”

"You...... You are so vicious, I will not let you go if I become a ghost......" The dying curator pointed to the scholar and cursed the murderer with his last life.

"Then I will fulfill you!" The scholar kicked the giant knife with his foot, and swept towards the curator's head with a strong wind, and when the giant blade slashed his head, the head actually had the effect of being shattered, and it splashed in all directions, but the fragments that fell on the ground were still flesh and brains.

"Good knives!" Wan Rongbing praised.

"A good knife indeed!" The scholar looked at the knife in his hand, "This ghost bone Nai He Bridge has the magic skill of 'Judge Under the Knife', which can turn the opponent into stone or glass at the moment of slashing, no matter how strong the body is, no matter how hard the weapon is, it can't resist its blunt blade...... If it weren't for my plans, it would have been nice to stay and have fun. ”

"Senior, where are we going after that?"

"Go find the other two demon knives, and 'visit' a few old friends by the way." His eyes flashed with a fierce light, "Soon my plan will come true, how the world has treated me Liu Mengyuan, I will get it back!" ”

The true face exposed in an instant made Wan Rongbing, who was standing behind Liu Mengyuan, tremble, this man who "died once" would be a nightmare that ended this world.

This feeling of ruining the world made Wan Rongbing uncontrollably excited......

……

Early the next morning, the two went to Professor Wei's side, and he actually used those simple parts to modify them into remote control electromyography inputs. This thing is an integrated electrical plate on the back of the back, and many wires are protruding from it, and the end is connected to the acupuncture and inserted into the muscle. This integrated board is used for power supply on the one hand, and wireless signals on the other hand, and the remote control of it is a modified integrator. …,

"Wow, you can figure this out!" Lu Su exclaimed, "I thought there was an antenna attached to each needle." ”

"How can it be done, can't each needle be connected to an external power supply! Let's try to see if it's comfortable. ”

"Hell if you're comfortable."

When the two were busy giving Lu Su a needle, Lu Su said, "Professor Wei, I have a piece of paper in my left pocket." ”

"Is it a thank you note?"

"No, it's a blueprint."

"Do you know how to draw designs?"

"What do you mean by that look of contempt, take it out and see."

"Okay, I'll see."

Yesterday and Jin Duan discussed the backpack wings, Lu Su drew the idea at night, although he felt that it was very difficult to occupy Professor Wei's research time to do this, but it is better to go to three than to ask for one, among the people he knows, he is probably the only one who can get it, and he can't go to the Kinoshita cicada far away in N City, he doesn't want to deal with the demon slayer now.

Professor Wei unfolded the drawings in his hand, and the circuit diagram drawn by Lu Su, who even failed junior high school physics, was completely unreliable, and he had no talent for drawing, and the whole sketch was messy and had to be marked with words. The general meaning is a bag that is carried behind the back, with rings on both sides that can be pulled apart, two on one side, and the wings are pulled out as long as the brocade is pulled with the auxiliary arm.

Professor Wei frowned and looked at it for a long time, and Willie was also watching from the side, and she was the first to call out: "Wow, it's amazing!" ”

"Haha, it's over."

Professor Wei understood: "There is one biggest flaw in your idea. ”

"Didn't you apply for a patent?"

"Nonsense, how can such an invention be promoted...... The biggest flaw is the lack of a power system. ”

"You don't need that, just fan your wings like this, and you'll fly."

"Whimsical! Do you understand aerodynamics, it is impossible for a person to flap his wings and fly like a bird...... "Apparently he doesn't know Yibi," someone tried this in the last century, and all of them failed without exception. ”

As he spoke, he took out a ballpoint pen from his pocket and revised it on the drawing: "Look, just add a booster with compressed fuel." ”

"Oh, that's it."

"Far away, the booster is theoretically feasible, but the temperature is too high, and many details need to be modified, otherwise it is impossible for people to use it."

"Professor Wei, that ......" Lu Su tried to say it like a little bit, "I think can I ask you to make it, I'll produce the materials or something, but it's not for nothing, I can pay for it...... Remuneration! ”

"Okay, you can pay according to my class fee, and charge forty an hour!" Professor Wei didn't seem to care about talking about money at all, and simply agreed.

"That's too little."

"Then you invite me to dinner, and you can pay for the materials."

"Eun!" Can't you make a fortune, being a man is really too kind, but if you add money, you're embarrassed to say it.

"I'm going to have to make it really cool!" The brocade next to him said, "Gothic, like Batman." ”

"That ......," Professor Wei scratched his scalp, "I'll do my best." ”

After talking about the wings, the battle training between the two began. The two often fought against each other, so there was no tension at all, but the electromyography device controlled by Professor Wei had been interfering with Lu Su's movements, and it became a little troublesome to move his body flexibly, and this one was completely defeated.

"You see, training is training, and actual combat is another matter entirely." Professor Wei said.

"Let's try again."

It feels like there's a ghost lying on you, fighting it for control with your will. Sometimes I was ready to stretch out my left hand to receive the call, but I couldn't lift it. However, the training in the previous few days was not in vain after all, and after feeling the feeling, I could gradually take over the attack of Jinduan...... In fact, in order to cooperate with him, Jin Duan deliberately slowed down his movements a lot. …,

After three hours of practice, Professor Wei said, "Now take the device off and you can try again." ”

"I'd like to practice a little longer."

"It's okay to get it right, come on."

Who said that it should be consolidated repeatedly! Lu Su thought to himself.

When I removed the EMG device, I suddenly felt that my body was much lighter, not because of the lighter weight, but because of the lightness of the hands and feet. He moved his hands and feet and stood face to face with Jinduan: "Come on!" ”

"You're welcome!"

Jin Duan leaned over and quickly rushed in front of him, the two exchanged wrists, and Lu Su held her wrist with his backhand. These movements have been familiar for a long time, but at this time, they have become much faster, and it seems that the body can react at the first time. In the past, he suffered a loss in the battle with Jin Duan because his hands and feet always couldn't keep up with his eyes, but this time he was able to barely tie with Jin Duan, as long as his eyes saw through it, his body could naturally break his moves.

This feeling is really comfortable, as if the power of the whole body has been completely liberated, and it can move as you like, at will. The two of them actually fought for ten minutes, and Willy and Professor Wei on the side were dazzled, and finally Professor Wei shouted to stop.

"That's amazing!" After stopping, Nishiki clapped his hands and said.

"Haha!"

"How?" Professor Wei asked, "The body seems to have been reborn, this is like removing the weight on the legs can make people faster, and your muscles are now quite active." ”

"It's really effective, it's only a few days."

"Diligence and method are very important, diligence depends on yourself, and I will give you the best method...... Even if the second phase is over, rest today, and start the third phase tomorrow, and the third phase of training focuses on strength. ”

"Is this the end of it?" Lu Su said disappointedly, "Why don't you start now, I feel like my body has become very powerful." ”

"Start now?" Professor Wei touched his chin, "Then please be prepared for a fracture all over your body!" ”

Later, Lu Su realized that his words were not exaggerated at all, compared to the training content of the third stage, the first two stages were like games.
