So that after he changed the tendons of several small beasts, he found a suitable one, the length is enough, the toughness is enough, especially the surrounding environment is very humid, and the quality after drying is not very good, which he did not expect, but there are still a lot of air-dried, as long as it is moistened with water, gently patted into a silk, and then twisted into a thin rope, so that it is best to use it to make crossbow strings.

The crossbow string is there, and then there is the wood used to make the crossbow machine, how much and how much, the tree outside the fence can't help but be tough, and the hardness is just right, the key is that it is very small affected by the humid environment, and when the time comes, it will be coated with oil and roasted with fire, and the best crossbow machine can be made.

What makes Tong Yan the most headache is the material for making crossbow arrows, what crossbow arrows need is hardness, pointing at it to kill the enemy, ordinary trees definitely can't do it, although it can shoot into the soil, but if you want to break the skin of the beast, don't even think about it, the key is that he can't make metal arrows.

Unexpectedly, Tong Hu found a cyan tree, this kind of tree is harder than stone, this is really a godsend to make arrow materials, but because the tree is too hard, it is not so easy to intercept, this point after he got the tools, there is no need to worry at all, although there is no saw in it, but he can do it, this is just the beginning of the stage, and in the future, he will also make the intercepted wood into arrows, this package of tools will come in handy.

Before Tong Hu asked him why he carried so many black stones, getting so much coal is not for heating, but an indispensable part of making crossbows, not only for baking and molding, but more importantly, it can heat the blade, even if the wood is hard, it is afraid of fire!

The heated blade can also be used to rough the crossbow arrows, which is a very labor-saving method.

In front of Zhen's eyes, Tong Yan did a broadcast gymnastics, originally he still wanted to play a set of Tai Chi, but his memory was limited, he didn't know some key points of Tai Chi, and he couldn't find the essence of Tai Chi, so he simply did the most familiar radio gymnastics.

Zhen shook her head, she really couldn't figure out what the use of Tong Yan doing some movements was, the softness would not increase his strength at all, it was just that he was too young to play.

At the end of more than ten minutes of radio gymnastics, Tong Yan took a deep breath and returned to the house to eat comfortably, at this time Tong Hu had just gotten up, and he didn't wash his face and went over to eat, Tong Yan sighed in his heart, I really don't know why this guy is not sick and so unhygienic.

"Tong Hu, wait a minute, I need your help. Tong Yan said to Tong Hu, who was reincarnated by a starving ghost.

The copper kettle was stuffed with something in his mouth, and he said indistinctly: "Today I am going to go out hunting with Uncle Ema, won't you come?"

Tong Yan shook his head, thought about it and didn't say anything, now he doesn't need him, but he has to suffer a little more, and after a while, Ema also got up, and under the urging of Tong Hu, he hurriedly ate breakfast.

Ready to stop, they were going out hunting, Oma asked Tong Yan several times if he wanted to go together, Tong Yan just shook his head, this is something Oma can't understand, it is very attractive to be able to go out hunting with Abba when he and Tong Yan are so old, why is this attraction completely ineffective when it comes to Tong Yan.

"Abba, I'm not feeling well today, you and Tong Hu should go, and I will ask you to help you when you come back in the evening." Tong Yan said with the appearance of a child.

Ema nodded helplessly, so she had to lead Tong Hu out, Zhen was sewing animal skins in the house, she was going to make another animal skin clothes for the family, and she didn't care what Tong Yan did.

Tong Yan took out the tools from the cowhide bag, and found a seriously damaged iron sword that he had picked up before, and he didn't know what metal the set of tools in his hand was made of, it was much harder than iron, but it was more than half lighter than iron.

The iron sword was badly damaged, the front end was rusted and could not be used, and the middle was up until the hilt was still intact, at this time Tong Yan was holding a chisel and carefully smashed the gap in the blade.

The iron sword is as wide as the palm of your hand, except that the middle of the blade is a little thick, and the sides are very proper, and it should be able to make a handy saw.

After scrapping for more than an hour, the preliminary work was finally completed, and then the file was changed, and the gap just made was rubbed out of the edge, so that the sawing wood was also sharper, but it was not beautiful, because he did not have finer tools, and the saw blade could not be made pointed, which was very affecting the use, but the restrictions of the conditions could not be helped.

By the time everything was done, the sun had already risen, and he exhaled deeply, which was still very heavy for his four-year-old body.

Carrying a saw, he took a knife and secretly ran out of the door.

He was not in a hurry to make the wood for crossbow arrows, but now he needed to find a trunk that was always old, and brought it back to prepare to make a crossbow machine, and he didn't go far before he hit the target, a tree that was not thick or thin, this tree grew very inconspicuous, but Tong Yan liked one point, this tree grew out of a rock crevice, and the surrounding trees were very thick, in comparison, this tree grew very slowly.

Tong Yan knows one thing, but any slow-growing large tree system is better than a fast-growing one, so this tree is the best choice.

Feeling the thickness of the trunk, he wanted to cut it off and probably wouldn't have to do anything else this day, so a fork branch in the middle became the best choice now.

For climbing trees, Tong Yan is also familiar with the road, fixed the saw on his body, he climbed up in three or two, sat on the forked branch, five meters away from the ground, and looked at the bottom is still a little worried.

I took out the saw, measured the position, and started to work.

Woo la ~ Woo la ~ Tong Yan's forehead gradually sweated, this job was still unexpectedly difficult, not that the tools were inappropriate, but the limitations of his body, the body of more than four years old was indeed not something he could do what he wanted.

So he hurriedly stopped and rested three times, Tong Yan finally sawed off the fork branch, and fell to the ground with a clatter, he leaned back weakly, gasping for breath.

After breathing, I carefully came down from the trunk, and the fork branch that fell down was more than four meters long and as thick as a thigh, and I was afraid that the bark would have to be washed a lot.

The next step is to cut the branch to the same size and transport it back to complete it.

It's a busy time, he is really a little out of strength, because he didn't expect the wooden structure of this tree to be so good, looking at the annual rings above, layer by layer is very conspicuous, roughly counted, there are almost twenty-six circles, that is to say, this tree has grown for twenty-six years, such a long time, it has become like this, it is indeed very rare.
