Egypt is a famous ancient civilization, and this country is undoubtedly the most well-known is undoubtedly the pyramids, many people have been curious to think, in ancient times how the ancient Egyptians moved those used to pile up the pyramids of the boulders, you must know that the stone is hundreds of pounds in weight, want to transport from the stone production area across thousands of miles to the pyramid construction site, in that era is undoubtedly a very difficult thing.

Naturally, modern engineers have come up with what they think of as a pyramid construction scheme, which naturally includes how to move blocks and boulders without lifting machinery.

Shen Nong chose to major in architectural engineering when he was in college, and when he went to class for a hypothetical plan for the construction of the pyramid, those teachers would occasionally use it as an interesting story to talk about, but Shen Nong could be regarded as remembering a few reliable ones, which would be just right to carry the big tree.

Usually when you are carrying heavy objects, if you can put a few round iron pipes of the same size or round wood under the heavy objects, so that you can save a lot of effort to push the heavy objects, because the circle has good rotation, and you can also carry the heavy objects forward while rotating.

If the hundred-meter straight road that Shen Nong asked everyone to dig just now is paved with a large number of logs, it will become a 'conveyor belt', and then move the trees to this straight road, then everyone can easily push the trees all the way to the Huangqiu tribe.

This kind of work is obviously not something that can be done in a matter of time, first you have to find the right tree, and then you have to cut the trunk to a length that can be placed horizontally into the road.

The sun was gradually setting in the west, and the sky was gradually darkening, Shen Nong knew that the safety hazards in the forest would increase greatly after nightfall, so he shouted to all the clansmen: "Speed up and see if you can transport this tree back to the tribe before it gets dark." ”

At this time, about thirty short logs had been placed in the 100-meter straight, but this was far from enough, at least ten more logs were needed to barely push the sawn-down giant tree back to the tribe.

Under Shen Nong's urging, those Huangqiu people suddenly accelerated the progress in their hands, and soon brought back a bunch of logs, and after they laid these logs neatly in the straight road, the action of carrying the giant trees could officially begin.

Shen Nong commanded, and immediately all the clansmen present walked to the side of the fallen giant tree and began to push the giant tree towards the position of the 100-meter straight.

"Come on, all the hard work!" Shen Nong shouted, at this moment he could no longer stand by and watch without making any effort, after all, one more person can have more power to push trees, but Shen Nong, who is a quasi-soldier, is not lazy.

"One, two, three, push!"

With a shout, the giant tree suddenly moved forward at an extremely slow forward speed, and even the dirt on the ground was ploughed out by the trunk.

With the unity and cooperation of everyone, the giant tree was finally pushed into the 100-meter straight.

"......Huh" Shen Nong held on to the trunk of the tree, standing in place and couldn't help but breathe a sigh of relief, the physical strength required for this work was really tiring enough, even if he was a quasi-warrior at this moment, he couldn't help but feel his arms a little sore and numb, not to mention the other ordinary clansmen.

"Wu, is this all right?" asked in confusion.

"Well, okay, push it, you guys push it now and see that the bottom province is not effortless. Shen Nong stretched out his hand and patted the surface of the trunk and said.

For Shen Nong's behavior, everyone was full of doubts in their hearts, but when they saw Shen Nong's confident appearance, they still chose to believe it, and one by one they put their hands on the trunk again and pushed it hard.

But this time the situation is different from just now, this giant tree is unusually easy to push, and it is not difficult at all!

I saw that when the giant tree was pushed, all the logs paved in the 100-meter straight road rolled straight forward, and then carried the giant tree to move quickly, which was several times faster than when Shen Nong and the others pushed it straight just now.

"This!" Cang was extremely surprised, at this moment, the weight of the giant tree itself seemed to no longer exist, making it very easy for them to push, Cang couldn't help but be impressed by the design proposed by Shen Nong again, the use of this hundred-meter straight road simply expanded the horizons of Cang and the others.

Thundered!

In a violent rolling sound, the giant tree could be regarded as successfully reaching the Huangqiu tribe, and when the tribesmen standing on the grass saw this huge trunk that suddenly rushed out of the forest, they couldn't help but be startled.

"They've really brought the tree back!" said someone in surprise.

"Go and help. ”

Immediately, the clansmen who reacted trotted over to help Shen Nong and the others carry the tree, as soon as they entered the Huangqiu tribe, the 100-meter straight road had already come to an end, if Shen Nong and the others wanted to move this giant tree to the dug ravine, they would have to rely on brute force.

Fortunately, because the sun was going down, the clansmen who were digging the ravines had already stopped working, and they just happened to have time to rush over to help Shen Nong carry the trees. As the saying goes, there is strength in numbers, and in a short time, the trunk of the tree has been moved to the side of the ravine to the north.

"Wu, what are you going to do now?" asked Cang.

"Let's just pile them up here, and when the trees come back in more numbers, we'll get ready to start work. Shen Nong clapped his hands and said.

To be honest, at this moment he began to look forward to what it would be like to insert the trunks of these giant trees side by side into the ravine, it must be very spectacular.

As night fell, the earth began to fall silent, and a bonfire in the center of the meadow was burning, and the people of the Huangqiu tribe all sat around the bonfire, enjoying a rare rest time in the day.

"Chief, we're running out of food in our tribe. An old man walked up to the bear sickle and said.

"What? so fast! Didn't there be a lot of jerky before?" said the bear sickle, with some surprise.

"Recently, the tribesmen of the collection team and the hunting team have not gone out to look for food in order to help the witches, and the jerky is not enough to eat. The old man said flatly.

"It's really troublesome. Xiong Scythe couldn't help frowning, compared to the wall, the importance of food is undoubtedly greater, after all, they don't know if the insect tide will come, and when it will come, when the enemy does not appear, the meaning of the wall is not very great.

However, once there is no food, the tribe will be at risk of starvation, and Xiong Yao, as the chief, naturally has to consider these problems, so he made a decision: "When the sun rises tomorrow morning, I will go out with the hunting party to find food, and the others will continue to stay in the tribe to help dig the ravine." ”
