After Xiaolan waited for Yang Yi and Xiangyi to get up, the four of them left the room together.

The entire vast land of the central city is their home, and unlike the so-called deep palace compound, the central city is a part of the home except for the administrative district, and they can do whatever they want at home, and they can get up at what time they want, and no one will come to care.

Of course, Di Xin is busy now, if he is not busy, he will definitely send someone to tell Xiangyi to get up and practice, and Xiangyi will get up early and run away when he has no choice but to find him.

But now that she has a husband, Di Xin won't treat her like this anymore.

After all, she is now Yang Yi's woman.

After having lunch with the two imperial wives, Xiangyi and Xianglin stayed and parted with them, after all, I don't know when I will come back, sensitive and sentimental women still need a while to tell each other's inner reluctance, especially mother and daughter, the two imperial wives must have a lot of things to explain to them, this time is completely different from the last time.

Yang Yi went to find Di Xin accompanied by Xiaolan.

Di Xin: Since Yang Yi taught him to make weapons, he has been out of politics, and most of the rest of his time has been spent on weapon research and development.

He was a man who loved to study, and although Yang Yi gave the craftsman a mold to make the weapon, Di Xin personally participated in the entire process of making the weapon.

The craftsmen are responsible for forging and melting the best metal materials, while Di Xin experiments to find better metal materials.

The weapon Yang Yi showed him was unique, and it was difficult for any metal material to achieve that effect, but he was not a person who liked to compromise. Now that you've started making it, you just have to do everything you can to do it to the best you can.

When Yang Yi passed, he was smelting metal in a refrigeration room.

There are a total of ten small furnaces in the refrigeration room. The fire was blazing in each furnace, and Dixin sat in a chair in the corner, using his energy to sense the properties of a pile of metal scraps on the table. Simulate the effect of multi-metal fusion in mind.

"Ahem." Yang Yi deliberately made a little noise.

"Just say something, I'm busy here." Without looking up, Di Xin continued to test the metal material in his hand.

Yang Yi sat down in front of him.

"You can't find someone else to do these things, right?"

"At my level of strength, I can sense the characteristics of metal materials through energy, which is convenient for integration in my mind, and I can make better alloy materials more efficiently, which others are not up to." Di Xin finally put down the metal in his hand, looked at Yang Yi and said, "When you come back, you will play with them in Central City for a few more days, you are in such a hurry to come to see me, and you plan to leave?" ”

"I've been in the Dark World for a long time. There's still someone waiting for me at home, can you not worry? Yang Yi played with the metal material on the table and said: "It's almost enough to set a limit value, there is no need to pursue the limit too much, the combat effectiveness of most of the warriors is within an average value, and what is needed is also a weapon for normal use." High-lethal weapons are powerful, but don't forget that they are very laborious to use, and giving them all high-lethal weapons will reduce the lethality in battle. ”

"There are also fighters with high combat effectiveness, not to mention, these weapons with higher lethality are provided for them to use." Di Xin said: "After that, I will test which weapon with different strengths is suitable for which killing range." This is used to generate weapons in batches, and then weapons are issued according to this standard. ”

Yang Yi shrugged his shoulders, whatever happened to him, he had his plan anyway.

"I won't tell you that. Father-in-law, I came to you to tell you that I may be going back in the next two days, and if you don't want to send us off, you should say hello. Xiangyi, they are saying goodbye to their mother, and they may come to you later. Yang Yi said.

"You can go again tomorrow. I have a clue in my head right now, so I'm not going to leave here. I'll see you off tomorrow morning. Dixin said.

Yang Yi looked at his old man with tears and laughter. He really can, his daughter is about to go to another world, and in his eyes, it seems that they are just going out, and he doesn't see anything to worry about.

Men and women are really not different at all, the two emperors' wives heard that they were going to the earth, and their faces were full of reluctance, he was good, he was not worried at all.

Also, with him Yang Yi here, he has nothing to worry about.

Yang Yi smiled.

"Okay, then you can do it yourself, I won't help you." Yang Yi got up and left.

As soon as he walked out of the door, he turned back again.

"What's wrong?" Dixin looked at him.

"I remember something." Yang Yi stretched out his hand, there was an extra gun in his hand, and at the same time, an energy condensed into a bullet in front of him, he said: "Combat energy can be controlled as you like, but most of the use distance is limited, if the combat energy is condensed into a bullet and loaded into this gun, as a bullet to shoot out, the distance will be greatly lengthened, and because of the compression effect, the power of the explosion will be even more fierce." ”

With that, the energy bullet vanished and recoalesced in the chamber, and he raised the muzzle of his gun, and with a thud the shot shot straight through the roof, the bullet exploding in the air from a safe height.

With only 100,000 combat energy, the power still caused a sensation among the soldiers in the entire military protection area, and they thought that someone wanted to attack the central city and immediately prepare for battle.

"It's a test, it's all back to their posts." Di Xin's voice spread throughout Central City, and his gaze as he looked at Yang Yi was full of surprise.

The combination of combat energy and this powerful weapon makes the burst of power truly extraordinary.

Yang Yi put away the weapon and smiled.

"While combat energy requires control and cannot be used as infinitely as ordinary metal bullets, a moment of crisis can be of great help. If you find it useful, train your fighters to master the art and train them to condense their combat energy into bullets. Okay, you can play by yourself, I'm leaving. Yang Yi patted his ass and swaggered away.

Di Xin smiled, and smiled happily.

This trick is a must.

Directly extend the range of combat energy and increase the explosive power of combat ability, when fighting, perhaps the use of combat energy can turn the entire battle tide, especially when the monsters attack on a large scale, all the warriors shoot energy bullets at the beast herd together, and absolutely kill a large number of monsters.

This is a great idea, and the only thing that needs to be overcome is to give the fighters a lot of control to condense the combat energy into a small bullet.
