The book says that sweet potatoes are also called sweet potatoes, because they were spread from foreign devils, and in the village they are called red potatoes, because they are similar to yams, that is, yams. Sweet potatoes are the main force of feeding pigs in the village, and they are also used to make starch, which is full of hunger during the famine, and almost every household has planted it.

"Sweet, sweet~~!" Wu said repeatedly.

Seeing this, Zhang Heng thought about it, and simply told everyone to stop first, and everyone cut a small piece, but he didn't dare to cut more, now there are only a dozen or so in his hand, if he really can't resist the passage of time in the space when he goes out, and he doesn't plan to stay in the space for a long time this time, because he has to ensure sleep time, and in reality, he will go to the interview early tomorrow morning.

"King, harvest, sweet!" The taste of sweet potatoes won everyone's cheers.

Thinking of sweetness, Zhang Heng suddenly remembered that he should bring some sugar to the primitive people, in the past, relatives in the village were to send two packs of sugar, and the old people used it to drink water, although he did not participate in the school sports meeting, but also saw that the students who finished the game had to drink white sugar water, saying that it was to supplement charcoal water compounds or something, although Zhang Heng did not understand very well, but there was nothing wrong with occasionally supplementing sweetness in the body.

nodded, didn't think much about it, beckoned everyone to continue to work, not for a while, but seeing that there were too many people, he simply beckoned some of them to the side to start digging the pit, as for the effect, because it was really impossible to explain, Zhang Heng had to demonstrate it in person, and sprinkled ~~ urine into the pit in public~~

"This is called a manure pit, and it will be excreted in the manure pit in the future to water sweet potato seedlings...... "It doesn't matter if Wu can understand it or not, anyway, Zhang Heng explained it in detail!

At noon, this time Zhang Heng was justified in greeting Ba to start the barbecue, and cheekily explained to Wu that he had to replenish his physical strength after labor, but in the end, the primitive people ate very little, and Zhang Heng only ate seven minutes and stopped eating.

In the afternoon, everyone was beckoned to continue to work, the cave was facing the east, and the direction was said, Zhang Heng patiently explained to Wu the early morning, morning, noon, afternoon, evening, and night, and also said the word moon at the same time.

"Sun, early morning, morning ......," Wu muttered repeatedly throughout the afternoon, and began to carve on the stone wall again.

Zhang Heng smiled with satisfaction, and then led everyone to start kneading the soil, although the dozens of square meters of the place were softly stacked, but not delicate enough, if there is a hoe, you can dig and knock it fine, but now you can only use your hands.

Fortunately, the palms of primitive people are quite rough, and it is not difficult to pinch the soil at all, and there are more than 40 people in the Spring tribe plus children, and the labor force is completely sufficient.

"Yes, that's it, pinch the soil finely, pinch it badly!" Zhang Heng greeted him and followed suit.

In the afternoon, this piece of soil was all pinched finely, but Zhang Heng always felt that something was wrong, and when the evening came, it was time for the Spring Tribe to eat, so he had to put his mind aside first, and then eat well!

――――――――――――――

The next morning, Zhang Heng finally reacted, it turned out that the land was too flat, so it was not suitable for cultivating sweet potato seedlings, because the sweet potatoes would rot if they were blistered, and hurriedly beckoned everyone to start moving the soil, and came from another place with their hands to hold the soil, although it was a stupid method, but the efficiency was very high.

By noon, the height of the land exceeded the plane nearly ten centimeters high, after thinking about it, Zhang Heng divided the land of about 50 square meters into several pieces, and dug out the trench in the middle to distinguish, and the periphery also dug out the ditch, which is used for drainage, if it rains, the rainwater will flow out along the ditch to avoid soaking the sweet potatoes.

After finishing this, Zhang Heng patted the soil on his hands with satisfaction, and suddenly shouted embarrassedly: "Everyone has it, come and pee now, well, just come with me." ”

Saying that, Zhang Heng peed again in front of everyone, sprinkled on the ground, and hurriedly covered the key parts with animal skins when he was done, explained to Wu, and then hid his face and went into the hole, and he was happy, when did he have such a thick skin, and peed in public several times......

When I went out to see it in the evening, good guy, sure enough, there were many people and a lot of excretion, and the fertilizer and water did not flow into the fields of outsiders, so I couldn't continue, and if I continued, the land would become a dung pit, and at this time, the big dung pit next to it was also dug up, so I had to demonstrate it in public again, so that Wu could only excrete in the dung pit after figuring it out!

――――――――

It was another early morning, and Zhang Heng planned to go out, because the land needed to be sunny, and he would not plant sweet potatoes for the time being; In addition, because the original space did not have a film, that is, the plastic transparent film used in the village to hide the temperature of the seed field.

Although there is no film available, alternatives can be found, this is also the previous soil method in the village, that is, to cover the seed ground with pine needles, the effect is almost the same as using film, Zhang Heng has not paid attention to whether there are pine trees in the forest before, but he is not worried, even if he does not, as long as he finds similar conifers.

Thinking of this, he roared: "Ba, go, come with me into the forest, well, let's go to the cuckoo first." "Although I have more confidence in my own combat effectiveness, in order to be on the safe side, it is better to call Cuckoo and the others, otherwise it will be a tragedy if you encounter a herd of beasts.

"Woo, cuckoo~~!" Ba roared.

In this way, Zhang Heng hung two pig-killing knives on his waist, held pig knives and spears in his hands, and set off with a tyrant carrying a double axe, fortunately, the journey to the Spring Tribe was not too far, and it would take about two hours to arrive, and Zhang Hengsuo ran up.

Gradually, he also confirmed his previous thoughts, only in terms of running, Ba's speed was not as fast as his, but Zhang Heng didn't dare to run ahead by himself now, in case he encountered a herd of beasts, it would be over.

Adjust his breathing, keep the same speed as Ba and run all the way forward, his sense of direction is not bad, he should be able to find his way back to the Cuckoo tribe, but before he dares to go out alone, his training results are just a showcase, and he still needs to go through the baptism of battle blood!

"Wang, ahhhhhh It's the sound of the cuckoo.

When Zhang Heng heard this, he responded happily: "Cuckoo, I'm back, the king is back!" ”

"Ahh The voice was close, I didn't think that Bugu and the others also came this way along the road, the eight men were there, and the height, Zhang Heng found that Bugu and the others had grown a little taller......

"King, woo~~!" As soon as Cuckoo and the others ran closer, they whined, and their eyes were full of joy.

Zhang Heng was also in a good mood, stepped forward and patted the shoulders of the eight men one by one, and when he got closer, he felt that Bugu and the others had grown a little taller, and suddenly that bold idea came out again, "Could it be that Bugu and the others are still only half-grown children?" Ba's height is the normal situation of primitive men? Could it be that because he entered the primordial space, the growth rate of primitive people also slowed down? ”
