Spring planting, summer growth, autumn harvest, winter storage.

The emergence of agriculture has made the history of that world revolve around these eight words, although the location of the tribe, there is no obvious distinction between solar terms, but the farming method has not left these eight words.

The corn planted is people's hope for a better life in the future.

Sowing seeds after the rain eliminates the need for heavy watering, at least for a while before the corn sprouts.

A large number of people were idle, and in addition to some of the people sent to the team that built the wall, others were sent by Wang Lang to transport copper ore.

With so much added to the population, there was a serious shortage of weapons and tools in the tribe, and often only two or three people could have a metal tool, and as for weapons, only soldiers could have them.

In order to solve this problem, Wang Lang sent Kong and his team to drive all the deer carts to the Dongfang mine the day after sowing.

A procession of forty or fifty men walked slowly across the steppe.

The creaking deer cart made an unpleasant grinding sound.

There are no roads on the grassland, and the wheels of the deer carts often get stuck in small dirt pits, and it often takes more than a dozen people to lift the vehicle up and move on.

Soldiers stood guard on the perimeter of the procession with weapons, and workers pushed the deer carts sweating and struggling to move forward.

This primitive vehicle is extremely inflexible to use, and even if it comes across a one-meter-wide stream, it can be very troublesome to cross.

After a day of stop-and-go, the team came to the creek where Wang Lang set fire for the first time.

Kong Yi looked at the small river in front of him, he was still somewhat sure of how to get through such a terrain, and the last transportation provided him with a lot of experience.

"Take the planks off the cart, put it on the river, unload the cart, and push the cart along the planks across the river." Kong Yi calmly commanded everyone.

After a busy time, a simple wooden plank bridge more than two meters wide was built, and the soldiers led the giant deer to cross the river first, and the rest of the workers, in groups of several people, pushed the vehicles carefully onto the plank bridge.

The heavy wheels creaked on the planks as if the simple bridge would break at any moment.

In a short distance of one meter, everyone can be said to be scared, if the plank breaks, such a heavy vehicle smashes on their body, and they are definitely either dead or injured.

Fortunately, the wooden planks are not suspended in the air, and under the double planks are three log piers of similar height, which disperse most of the weight.

After passing through the creek without danger, Kong Yi asked the materials for building the bridge to be unloaded again, put them on the deer cart, and after the giant deer was trapped, the team continued to move slowly towards the east.

On the way, a young worker, frowning and staring at the rolling wheels, looked like he was thinking hard.

Seeing that he was like this all the way, the companion beside him finally couldn't help but ask, "You have been staring at the wheels since you left the tribe not long ago, what's going on?" ”

The young man shook his head and said, "It's nothing, I just think there's something wrong with this wheel." ”

The companion looked at the wheel, but found nothing wrong, looked at the young man suspiciously, and said, "Isn't it nice that there is anything wrong with the wheel, how fast the wheel turns." ”

The young man smiled and said, "Maybe I'm thinking too much, this is a car made by the leader, how can there be a problem." ”

"Haha, that's it, what the leader does must be good." The companion laughed.

Although the young man said this, his eyes would still be fixed on the rolling wheels from time to time.

At night, the procession stopped in front of a small hillside, the soldiers lit a fire, and the workers began to prepare food for the night.

After a tiring day, after eating and drinking, most of the people, except for the vigilers, have already sunk who go.

In the night, the young man who stared at the wheels during the day couldn't sleep with his eyes open and tossing and turning.

Looking at the starry night sky, the young man asked himself, "What's the problem?" ”

"The wheels are rolling, the vehicle is moving forward, it seems that there is no problem! But why do I always feel that something is wrong? This doubt tormented him almost without sleeping, and it was as uncomfortable as if there were many insects crawling on his body.

The young man, who really couldn't sleep, sat up, looked at Kong Yi, who was chatting with the night watchman, hesitated for a while, took a deep breath, and walked towards Kong Yi.

Kong Yi saw a worker who didn't sleep at night, walked towards him, frowned, looked at the young man, and said, "Why don't you go to sleep." ”

The young man looked at Kong Yi and felt a little nervous in his heart, talking to someone with such status in the tribe was the first time since he joined the tribe.

Swallowing his saliva, the young man was bold and said, "Team Zheng, I have some questions that I don't understand. ”

Kong Yi sneered and said, "If you don't understand, don't think about it, there is anything in this world that you can figure out." ”

Kong Yi's attitude made the young man a little depressed, and he lowered his head and remained silent.

Seeing the young man standing there still, Kong Yi said with some annoyance: "Say what the problem is quickly, go to sleep after speaking, there is still a long way to go tomorrow." ”

"Team, why do our wheels and axles have to rotate together?" The young man asked.

Kong Yi and the rest of the soldiers who were on vigil, after listening to the young man's words, couldn't help but be stunned, what the hell is this, after reacting, these people got bigger, Kong Yi covered his stomach and said: "You guy doesn't sleep at night, I'm thinking about this stupid question, how can the wheels turn without spinning with the axles?" If you don't turn around, how can you walk! ”

Looking at the few people who were smiling forward and backwards, the young man was eager to find a crack in the ground at the moment, and at this moment he suddenly felt that he was the stupidest human being in the world, and everyone in the dark night could not see that the young man's face was already red at the moment, and he was extremely embarrassed.

"I see, team, I'm going to sleep." The young man saluted Kong, and quickly ran back to his place, lying on the ground to hide his stupidity in the night.

The team that had hurriedly eaten breakfast in the early morning continued to hurry, as if last night's episode had not happened, but the young man from last night deliberately avoided the sight of Kong Yi and the soldiers on duty at night, and hid himself in the crowd.

A day later, the mining team came to the baobab forest, which was still the same as when they first visited, and even the trees that had been chiseled out before could not see the scars, which showed the self-healing ability of the bread trees.

After replenishing the water here, the team arrived at the copper mine at noon.
