Half of the 100W germs died under the Night Rain knife, and Night Rain's physical strength and strength are not comparable to ordinary cells, after all, he has the existence of the system as an anti-heaven plug-in.

Ye Yu smiled very happily when he saw his experience, although the process of fighting was very tiring and hard, but the benefits brought were indeed real, 56W experience Ye Yu's mouth couldn't close.

The battle was over, and a large number of repair crews came to the battlefield to begin repairing the damaged tissue. Just when Yeyu was resting, a fleshy little hand reached out in front of Yeyu, holding a can of drink in his hand, and at the same time, a cute voice came: "That, brother white blood cell, hard work"

Night Rain looked up and saw a cute cute thing standing in front of him, it was platelets. Ye Yu smiled slightly, stretched out his hand and touched the other party's head, and said with a smile: "Little guy, you have also worked hard" After speaking, he reached out and took the drink handed over by the other party. Kawaii platelets laughed when they heard Yeyu's words, and with a big smile, they ran to meet their companions and continue to repair the broken tissues in their bodies.

"Whew" Yeyu pulled the drink and drank it, thinking about things while drinking the drink, and muttered in his heart: "I'm so tired, it's too slow to kill monsters like this, although I have a lot of experience, it's too slow and too slow, but it's very tired, if only I could have a submachine gun.... Zizizi"

"The host's idea is good, unless you can draw a hot weapon, you're delusional"

Ye Yu pouted: "Isn't this YY, by the way, can I build one myself" In the previous life, the state managed firearms extremely strictly, and civilians were not allowed to hold firearms, so they were sent directly if they were caught. But the manufacturing process of firearms is not strictly preserved, as long as modern people know the manufacturing principle of firearms, so Yeyu wondered if he could make it himself.

"It's okay if you want to make your own host, but how do you get the raw materials?"

Ye Yu said directly: "If you have iron, you can get it, and there is iron in your body."

"What about gunpowder" the system continued, and Yeyu was stunned for a moment, "yes, how did I forget this, gunpowder, this thing really can't be obtained here"

The night rain was depressed, iron was in the human body, and there was also lead, but gunpowder was not in the human body. The next moment, there was also a light in his eyes and said: "Since I can't make guns, then I can make bows and arrows, hahaha, I'm really a genius"

You don't need gunpowder to make a bow and arrow, you just need iron, and if you have branches, you can go to dendritic cells, which have a lot of branches and iron everywhere. At the same time, Nightrain has all the abilities of white blood cells, and even when using ranged weapons, it has great lethality.

As soon as he wanted to do it, Night Rain got up and walked directly towards the position of the dendritic cells. While walking in the night rain, he asked the system: "System, do you have a system store?" ”

The voice of the system came: "Yes, but the host your permission level is not enough to use the system store now"

After listening to the system's words, Night Rain stood still, and he originally wanted to make a bow, and then buy some feathers to make arrows in the system store. But the system mall is not opened, so the wooden arrows can only be abandoned, and the range and accuracy of the wooden arrows without tail feathers will be greatly reduced, and Night Rain has to think of other methods.

Wooden arrows can't be made, so ordinary wooden bows must be abandoned, so there is only one bow and arrow left for Night Rain to use, and that is the compound bow.

There are many types of compound bows in reality, but the style and function are basically the same, the difference is the arrows, one is the arrows for competitions, and the other is the arrows used for hunting. Hunting arrows with feathers. The tail feathers of the tail of the arrow used in the competition can be replaced by any material.

Night Rain turned around and walked back, returning to the place where the battle was held, and Night Rain found the platelets. "Doodoo, doodoo" whistles come and go, and a little Lori with long yellow hair is directing the friends to repair the city.

Night Rain came behind the platelets to say hello and said softly, "Platelets"

Platelets were directing the repair work when she heard someone calling her, turned around and saw Ye Yu squatting behind her and said, "Is there something wrong with Brother White Blood Cell?" ”

Night Rain asked with a smile: "That brother wants to ask, where is the factory" That's right, Night Rain just wants to know where the factory is, this world is full of high-rise buildings, and the point gas also has a very high water bottle, although there is no shot of the factory in the anime, but Night Rain knows that there must be a factory in this world. If not, then there is no way to explain these steels and cranes.

Sure enough, when he heard Yeyu's question, the little guy smiled and said, "That, that" while saying, he took out a map and said: "This is this place", and then stretched out a finger and pointed a location on the map.

Ye Yu looked at the place that the other party pointed to and knew what the place was, Ye Yu stretched out his hand and rubbed it on the other party's head and said, "Thank you, platelets"

Platelets smiled sweetly and said, "You're welcome" and then turned around and continued to direct the work of his friends, Yeyu smiled with relief when he saw these small figures. At the same time, I kept complaining in my heart: "The author is really BT, he actually designed platelets so cutely, and let them (them) do so much heavy work, shameless"

Night Rain shook his head and walked in the direction designated by the platelets, twisting and turning, and inquiring with passing cells along the way, and finally Night Rain came to the so-called factory.

A huge factory appeared in front of the night rain, and there were no guards or doormen here. Ye Yu saw the front door of the factory, and when he opened the gate, Ye Yu saw that a big man was busy working, some were directing, and some were waving huge iron pillars and knocking on the items in front of him.

"Yo, why are white blood cells free to come to us today?" Just when Night Rain was stunned, a big man with sunglasses came to greet Night Rain from the side. Yeyu nodded to the big man and said, "I want to make a weapon, my dagger broke during the battle"

When the other party heard Ye Yu's words, he was stunned and subconsciously looked at the seat of the dagger next to Ye Yu's legs, and sure enough, it was empty. (Nightrain retracts the dagger before it comes)

Dahan nodded and said, "Got it, I'll let someone make you two new daggers" After saying that, he turned around and was about to leave, Ye Yu hurriedly shouted: "Wait" The other party heard Ye Yu's shout and looked back at Ye Yu with a puzzled face.

Night Rain said directly: "I want to build a different weapon"

The other party heard that Yeyu said that he wanted to create different weapons, and he knew that no matter which world he was in, forging new weapons was extremely interesting to these forgers.

Ye Yu explained in detail to the other party the practice and precautions of the compound bow, and the big man kept nodding his head while listening to Ye Yu's explanation, and his eyes became brighter and brighter.

For 2 hours, Yeyu discussed with the other party for 2 hours before the other party thoroughly understood how to make a compound bow
