Although the face of the aphid is ferocious, it is unexpectedly generous to the identified friends.


    When ye Xi went back, they just gave him a big bag of aphids and sent him back. However, ye Xi saw that it was late, and he was afraid that the aphid would not have time to go back before dark, so he firmly refused.


    So he carried a bag of aphids on his back and a large bucket of rubber in his hands, so he went back to Tu mountain in big and small bags.


    Back in Tushan, ye Xi continued to make leather boots.


    First, he made a mold to imitate the sole pattern of mountaineering shoes. Then he poured natural rubber diluted with water and acid into the mold.


    The acid leaf Xi is extracted from the fruit of a plant, and its effect is no worse than that of the artificial synthesis in previous generations.


    After the rubber sole is made, all the materials are ready. The next step is to make leather boots.


    Ye Xi remembered that he had read an article similar to that of a shoemaker when he was reading. According to his vague memory, he measured the foot shape, made the last, and then printed it.


    It''s much more difficult to make leather boots than to make materials in front of them. It took Ye Xi a week to make a pair of comfortable leather boots.


    On the day when the leather boots were made, ye Xi could hardly bear to put them on. Looking at the familiar and unfamiliar shoes in front of him, his eyes were moist.


    I''ve been here for almost a year.


    He has almost adapted to the daily barefoot mountain road life, used to wear animal skin, used to squat by the campfire to eat barbecue. The civilized life he once lived seemed to be far away from him. Sometimes, when he looked at the two suns above his head and listened to the roar of dinosaurs coming from the jungle, he would be in a trance and wonder whether the memory of the past 20 years would be a dream of his own?


    But looking at the product of civilization - leather boots, the time when I was busy shuttling in high-rise buildings became clearer.


    Ye Xi put on his leather boots with red eyes.


    Tapir skin is soft and obedient to the feet, very comfortable. After pedaling in place, I found that the leather boots fit abnormally.


    Tu Shan people came to watch in a strange way. They bent over to look at Ye Xi''s leather boots, pointing and shouting.


    "Wow, you can still wear such exquisite things on your feet


    "It''s called leather boots. Ye Xi said that in the future, we all Tu Shan people will wear them!"


    "This I can''t bear to wear it. I''m afraid it will be damaged if I put it on


    "Me too. Even if it''s not damaged, what if it''s dirty."


    "Mr. Ye Xi said that it can protect your feet. If it''s dirty and wiped, it won''t be over. You don''t know."


    "Oh But rowing on leather boots is more painful than rowing on my feet. No, I still can''t bear to wear them. "


    Tu Shanren looked at the freshly baked leather boots, their eyes glowed, and they talked a lot. Some even poked their fingers carefully.


    Ye Xi said with a smile, "don''t worry, we will make this leather boots on a large scale in the future. Not only for our own people to wear, but also as a special product of our Tu mountain sold to other tribes. "


    After the day.


    Tu Shanren began to make leather boots as soon as he was free. The technology of making leather boots can not be disclosed. Therefore, the process of material making can only be undertaken by the men and married women of the tribe, and each group is responsible for one process. Finally, the women of the tribe will make the shoes.


    The first to put on leather boots were the soldiers of Tushan, because they often had to run outside, and they were the people who needed them most.


    After putting on leather boots, the soldiers of Tushan didn''t know how to walk at first. They didn''t adapt to it, but after a few days, they couldn''t leave it.


    Because with leather boots, they will no longer have to pay attention to the road on the ground and whether there are spines on the ground. In this way, they can travel faster and hunt more efficiently.


    Two months later.


    Ye Xi stood by the farm.


    Now the seedlings of millet and grass have already run to the thighs. They look green and pleasant, but some of them are yellow and look bad.


    Ye Xi touched the yellow millet grass with his hand.


    Millet grass is delicate and precious. Even if someone is specially assigned to serve it carefully, some of them are sickly. It''s not as good as those red mango vines, which are now crawling all over the shelf, opening small buds, and are about to blossom and bear fruit.


    A weak voice came from behind.


    "Ye Xi, can you help me see if these shoes are size 45? Is the size right? " Pheasants walk with a pair of leather boots.


    Because after Tu Shan wanted to sell leather boots as an industry to the people of other tribes, it was impossible to tailor them to each buyer. Therefore, ye Xi taught them how to make shoes according to the size. Because most of the buyers should be soldiers running around, ye Xi took an average value based on the foot size of Tushan soldiers, which was floating up and down based on the average value.


    Ye Xi turned back, took the leather boots, looked at it, and said with a smile, "I don''t have the ability to distinguish the size with the naked eye. As long as it is done according to the size board, it should be right.""Oh." The pheasant''s eyes lowered his head and took up his boots. He plucked up his courage and asked, "I see you''ve been wandering around the farmland these days. Is there something wrong here?"


    "Of course not." Ye Xiwei Zheng, smiling and shaking his head.


    He didn''t expect the pheasant to be so careful. In fact, he spent a little more time by the farmland these two days.


    He had been waiting for the news of the aphid, but he didn''t expect to wait for two months. He didn''t see them send someone over. Thinking about this in his heart, he walked to the edge of the farmland unconsciously.


    You''d better go to the aphid tribe by yourself. Ye Xi looked at the Yellow seedlings and thought.


    At this time, the grey beak ran to this side and yelled: "Ye Xi, ye Xi, the people who have the aphid come here, and they say they are looking for you!"


    As soon as ye Xi''s eyes brightened, he said to pheasants, "I''ll go over for a while." He rushed to the entrance of the valley.


    At the mouth of the valley.


    Several strong men of aphids stood there with solemn faces. They were fierce and sharp eyed. They looked like they were looking for stubble.


    A group of Tu Shan people stood on the other side. At first, the chief made a few words with a smile. Later, when he saw the aphid, his face was cold and solemn, so he shut up.


    When ye Xilai, both sides were silent.


    It''s like a confrontation.


    Seeing ye Xi coming this way, both sides are bright eyes.


    Tu Shan''s people want Ye Xi to get rid of these evil stars quickly, while the people of e''aphid feel uncomfortable all over. They want to say something to Tu Shan people. When they get to their mouths, they swallow them again.


    As soon as ebony saw Ye Xi, he jumped over excitedly and said happily, "the excrement of aphids is really useful to trees! We can be sure now! "


    Ye Xi looked at such ebony, and felt that there was a tail behind him, shaking happily, just like a big dog asking for credit.
