"Try it, which one is more convenient."

Fei Yi can always make some strange things, just like the little robot who could talk before, as well as strange bombs and strange sausages. In short, this guy gives Xia Xin a bit of a tech madman.

Xia Xin asked Fei Jie to get a handy dagger for himself. He finally discovered the importance of a handy weapon, just like the dagger he carried with him last time, even cutting the tiger skin was difficult.

Fei Yi handed Xia Xin two daggers.

"Time is limited, so I'll find someone to fight tomorrow, and that's all I can do."

One of them is a transparent dagger. If you don't look closely, you won't even see its trajectory.

Even Xia Xin had to take the dagger closer to see the traces of the dagger. Its size and shape are quite good, and the length is a little longer than ordinary daggers. This is exactly what Xia Xin wanted.

"How did this dagger do it?"

"This surface uses a light reflection technique, which looks like it blends into one with air, making people unable to judge the trajectory of the dagger with their eyes. I also did an illusion trajectory test of the human eye. Judging with the eyes or muscles, it will definitely be scratched. You can also see that it is longer than an ordinary dagger."

"This is good," Xia Xin sighed. He thought it was good to use the Yin Ren.

People think they can escape, but they will still be hit.

Fei Yi continued, "The disadvantage is that it will be ruined if it is bloody."

"..." Xia Xin said with a blank expression on his face, "What do you mean is that if I use this dagger, I can't hurt people, right?"

"Basically, this is true. Although I have done a streaming treatment, if the dagger is stained with blood, the blood will remain on the dagger and cause certain damage to the camouflage structure on the surface. Once it is stained with blood, the other party can clearly identify the trajectory of the dagger."

"... Then, I can't get blood, so why should I use it?"

"Also, be careful not to use too much force. This dagger cannot withstand too heavy blows, especially not to touch the opponent's force, after all, it is not an alloy."

"You can't get bloody, and you can't fight with the other party head-on. Can I take it with me and cut an apple?"

Xia Xin could only turn his attention to the second dagger.

This looks like a 10-yuan dagger sold on the street, without any characteristics.

"Didn't you say that you can make it longer? I'm not used to it when it's too short."

What Xia Xin used to use was a dagger slightly shorter than the dagger.

Fei Yi replied calmly, "It's based on the length you like."

He said, picking up the dagger, moving it to the table next to it, and moving it to a position about 1 cm above the table, "Don't look at it's only so long, it's used to deceive the enemy."

Just as Xia Xin was watching, the dagger, which was one centimeter away from the table, didn't even move at all, and the table was cut open.

"This dagger uses molecular cutting technology. Once the switch is pressed, the wind pressure on the surface can tear the prey even if it is not touched. You can imagine it as a chainsaw without teeth, using wind pressure and can cut the body without touching it."

"I'll go, you... Fei Yi, I've changed my mind about you. Are you so powerful? What kind of black technology is this?"

Xia Xin was a little shocked.

He took the dagger, pressed a small button on the surface, and gently moved it to his index finger. At a distance of about 1 cm, his index finger felt a little pressure, and then he was immediately bleeding.

"The disadvantage is that ordinary metal can be cut off instantly, but if it encounters a magic weapon, it may break it first, and... it consumes extremely power. I have used the most advanced battery. When the battery is fully charged, it can be turned on for 2 to 3 minutes."

"2 minutes, to 3 minutes? That's just a little time?" This made Xia Xin frown, "What would happen if the battery was not turned on?"

"Then this is an ordinary dagger, and it can't even cut an ordinary dagger. It has electrons inside it, not as strong as an ordinary dagger."

“…”

Xia Xin realized that Fei Yi was indeed very skillful, but he was a half-baked person, a dagger that was powerful and transparent, but could not be cut off people and could not be confronted by head-on.

Although one seems to be invincible and can cut people in the air, the effect can only last for 2 or 3 minutes. You have to pray that the other party is not holding a magic weapon, and his usual situation is not as good as an ordinary dagger.

"These two can be hidden close to each other, so, which one do you like?"
