章節 347: Type 82-2 Grenade

In actual fact, the items Ren Baqian brought back this time were a product used by the impoverished in the other world.

They were the bone arrows used by the winged cavalry.

Dayao couldn't afford to use iron arrows, but this type of bone arrow wasn't only very hard, it also had good stability. The arrows used for hunting in the mountains were also made from this kind of animal bone. When Ren Baqian returned to Earth, he brought along a few bone arrows with him so that he could hand it over to the laboratory.

In fact, he still had another idea. This idea popped up in his head after he returned to Earth.

The next time he returned to Earth, he would bring the corpse of an Earth Wheel expert back. He presumed that the researchers on Earth would be able to obtain important information from their bodies, including the direction of cultivation. This was something that he wanted to know as well.
