In the next few days, Ye Feng first taught them simple mathematical addition and subtraction operations, and found that they couldn't go on with addition and subtraction operations beyond hundreds, but more than a dozen young children in the tribe were easy to add and subtract operations within a hundred, which made Ye Feng sigh that education still had to start with dolls.

As for the issue of words, Ye Feng has not considered whether to directly copy the simplified characters of later generations or directly create a set of hieroglyphs. It is self-evident that words can convey the meaning of people's expressions, open up people's ways of communication, and make human civilization better passed on, and other benefits are countless.

Compared with words, it is better to choose a point, Ye Feng directly uses Arabic numerals, primitive people's thinking can not understand such abstract symbols, I don't know what those zigzag lines have to do with quantity, Ye Feng spent a long time before finally explaining it to them.

……

As winter turned to spring, the earth slowly shed her snow-white coat, revealing her brown skin, and the green leaves were dotted among them like stars in the sky. The sun finally has a hint of warmth, and it is very enjoyable to be exposed to the sun. The branches that have grown young shoots occasionally hear the song of a bird that has not been seen in winter, and it is as melodious as a gentle song.

Ye Feng stood at the entrance of the cave, sucked in the slightly cool air, and slowly spit it out. He looked at the scene in front of him as the ice and snow melted and everything recovered, and sighed that time really flies. It's been almost a year since he crossed by himself, and he was hopeless, but he didn't expect to gradually live and work in peace and contentment in this barren and primitive world. Originally, he thought that he would feel very lonely as a modern person, but with the appearance of Chu Yun, it made up for the gap in his heart.

Thinking of this, Ye Feng's mind couldn't help but think of Chu Yun's beautiful face, and the corners of his mouth couldn't help but have a hint of a smile.

"Hey! What are you giggling at? A tactful voice came from behind Ye Feng, Ye Feng was grateful that his shoulder was patted, he turned his head and saw that it was Chu Yun.

When I saw Chu Yun, I looked at her beautiful and moving face. Ye Feng remembered the information he had at the point where he crossed again, the Wu Mingyao in the information didn't know what the situation was now, if it was an enemy, he and Chu Yunke would be in danger, thinking of this, Ye Feng's face suddenly turned long.

Seeing this, Chu Yun thought that Ye Feng disliked herself, with her character, how could she accept it, she hurriedly shouted at Ye Fengjiao: "Okay, you Ye Feng, I saw you looking elated just now, my aunt and grandmother changed their faces as soon as they came, what do you mean, you!" ”

"What? What did you say? I didn't hear it. Ye Feng was thinking about Wu Mingyao just now, and his attention was completely inattentive. Hearing Chu Yun's words, he didn't react for a moment.

"Hmph, ignore you!" He turned his head and left, leaving behind Ye Feng, who was in a state of confusion.

………

"Whoa!" "Puff puff!" The sound of water being beaten came from the tribe's paddy fields. In the paddy field, a group of primitive people carried animal skin skirts to trample back and forth in the paddy field, their legs and feet were covered with brown mud, and from time to time because they jumped too hard, the splashed mud flew to their faces, noses, and even eyes and mouths, but these primitive people with thick nerves did not take it seriously at all, and were still trampling on it happily.

Ye Feng and Liu Junting stood on the ridge, looking at the working clansmen with their eyes like torches.

"Ye Feng, do you really want us to eat without hunting by planting this grass?" Liu Junting asked.

"This is called rice, not grass, as long as the planting area is large and the harvest is good, not only can our tribe be fed, but also have a lot left, which can be exchanged for the bazaar, and you can exchange it for a lot of things." Ye Feng replied.

"Then why did you tell them to step on the mud of this paddy field?" Liu Junting then asked.

Ye Feng knew that the more answers he had, the more questions he would have, so he quickly changed the topic: "Is the hay you prepared ready?" ”

"Oh, not yet, I forgot, I'll go now!" As he spoke, Liu Junting disappeared in front of Ye Feng's eyes at the speed of Liu Xiang's hurdles.

Ye Feng was speechless about this.

He prepared hay not to make a bed, but to keep the seedlings insulated, in later generations, the plastic film commonly used for seedling insulation, the production of plastic film that requires a complete industrial system, now not to mention what industrial system, even iron has not been developed, then not to mention.

He plans to breed rice with hay, which is not as good as plastic film, but it is better than nothing.

Ye Feng came to the place where he stored the rice seeds, and the dried rice seeds were wrapped in a piece of animal skin. Next to him, there was a plastic bag, this was the vegetable seed brought by Ye Feng.

To be honest, he hadn't looked at the varieties of vegetables yet, so he opened the plastic bag and found that the seeds inside were packed separately in small white plastic bags, and there were several.

He opened the first package of vegetable seeds, a spicy smell came, Ye Feng turned his head and let out a loud sneeze, if it wasn't for the quick reaction, I am afraid that a sneeze would spray this precious seed.

Ye Feng looked down at the seed, this seed was disc-shaped, yellow-brown, with a little red, the smell was spicy, and Duoye, who loves spicy food, immediately recognized this thing, this is the famous chili pepper.

When he saw the chili pepper, Ye Feng thought of the famous Sichuan cuisine, and then thought of Chongqing hot pot. As long as he has a little spare money, Ye Feng will go to the hot pot restaurant to order a pot, although it hurts to go to the toilet every time he eats, but he still can't stop it.

Eating chili peppers, I have to talk about Chongqing people, there is a joke on the Internet in the future, which is to say that the slight spiciness, in the population of Northeast China, is just to turn a little bit for decoration, and the slight spicy in the Chongqing population is just a symbolic little less. This shows that Chongqing people love chili peppers.

Although the food of the tribe is now full of salt and peppercorns, it is much stronger than before, but no matter how delicious it is, it will become bland and tasteless if you eat too much. Thinking of the hot pot made in the future, the corners of Ye Feng's mouth began to fully secrete saliva, dripping on the ground without knowing it.

He turned out a droplet-shaped seed, Ye Feng looked at it and guessed that it was a cucumber, he didn't know much about these seeds, he only knew a little about the skin, after all, he was not an experienced old farmer, and he could tell the type of seed at a glance.

Thinking of cucumbers, I didn't expect all kinds of meat jokes about cucumbers in later generations, and suddenly my mind was opened, and I thought: "If the cucumber is planted and given one to Chu Yun, how will she react?" The corners of Ye Feng's mouth pulled up a wicked smile, fortunately Chu Yun was not here, otherwise this thing would be unlucky again.
