Early in the morning, Xiong Kao personally left with the members of the hunting team, looking at their posture, this time it is very likely that they are planning to go to the foothills of the Black Mountain for a trip, although the drought has arrived now, but it is not ruled out that there will be herbivore beasts to graze there.

After Xiong Yao and the others left, Shen Nong naturally would not be idle, and immediately took the clansmen to move the trees, with the help of the 100-meter straight, presumably within today, Shen Nong and the others should be able to move back the trunks that filled a whole ravine.

"Wu, this tree is a bit far from our road, and there are trees nearby, so it's not easy to push over. ”

"You can't push it horizontally, can't you adjust it to a vertical shape and then push it?" Shen Nong said speechlessly.

I saw that the trunk in front of him was full of uneven trees, not as easy to push as yesterday's tree, if he forcibly pushed horizontally, he would be stuck by two big trees, so Shen Nong planned to turn around on the spot and push it to the side of the 100-meter straight road in a point posture.

This is actually a very simple thinking flexibility, for example, a person holding a long bamboo pole intends to walk through a door, but he finds that the width and length of the door are far shorter than the length of the bamboo pole, if you hold the bamboo pole horizontally, this person will definitely not be able to walk through the door anyway, but as long as he adjusts the direction of the bamboo pole and faces the end of the bamboo pole towards the door, then he can walk smoothly at this time.

Shen Nong and others are currently encountering the same situation.

After some adjustments, the group pushed the tree onto a 100-meter straight and quickly transported it back to the tribe.

After doing more of this kind of thing, they became familiar with it, and it didn't take long for Shen Nong and the others to transport five trees back to the Huangqiu tribe.

This speed is still being maintained, because Shen Nong had the foresight to let the clansmen sawn enough trees in the forest in advance, which directly saved Shen Nong and others the time of sawing wood, and directly transported the trees that had been sawed down back to the Huangqiu tribe.

About three hours passed, and a full fifteen trees more than twenty paces long were piled up next to the ravines to the north of the Huangqiu tribe.

The pile of trees was placed together like a hill from a distance, and if nothing else, they would all be stuck in the ravine.

Shen Nong stood next to the ravine, sometimes looking down at the bottom of the ravine, sometimes looking up at the width of the trees, carefully considering if there was anything that needed to be improved, the next action would be a very important step, and there must not be any accidents and mistakes.

When going to the Cangtao tribe before, Shen Nong's request to Cang and the others was to dig the gully ten steps deep, of course, because there were no measuring tools, this depth would not be so accurate, there should be an error of one or two steps, but it was harmless.

The length of these trees that Shen Nong asked to be sawed down is usually more than 20 steps, which means that after the whole tree is inserted into the ravine, the exposed surface of the earth will be at least ten steps long, that is, about five meters long, which can be regarded as the scale of the city wall.

With such a wooden wall protection, I believe that the security of the Huangqiu tribe will definitely be greatly improved in the future, and it will become an existence that is easy to defend and difficult to attack.

However, imagination is very beautiful, but it is not so easy to execute, this casually a tree weighs at least a thousand pounds, and it is easy to insert it accurately into the ravine, and then give it a stable stand, which is easy to say, but difficult to do.

"Whoever goes and brings two pieces of wood, let them be a little stronger and a little longer. Shen Nong said suddenly.

Immediately, some people from the Huangqiu tribe ran to find wood for him, because during this period of time, there were frequent construction problems in the Huangqiu tribe, so just in case, those clansmen who went out to cut trees also deliberately accumulated a lot of wood, which was enough for Shen Nong to squander for a while.

Soon four people each came running with two thick logs, just long enough to span the ravine, holding smoothly above the ravine.

"Hold these two logs steady and don't let them shake. Shen Nong instructed, and ran to the side of the big tree pile with the other clansmen, removed the tree trunk on top, and then pushed it towards the ravine.

Although the people of the Huangqiu tribe didn't know what Shen Nong wanted to do, based on their past experience, they knew that they only needed to follow Shen Nong's actions and do it, and there would be absolutely nothing wrong.

With the efforts of everyone, the big tree was quickly pushed to the side of the ravine, but at this time, how to make the tree erect and then insert it straight into the ravine became an extremely difficult matter.

You must know that this tree is so heavy that it cannot be lifted by human strength alone.

Just when everyone was feeling embarrassed, Shen Nong suddenly said: "You go and transport all the soil that was dug out of the ravine before by a board cart, and bring another thirty pieces of wood that are one person high." ”

Without any hesitation, the people of the Huangqiu tribe standing near Shen Nong took action one after another, pushing the cart of the cart, transporting the soil, and looking for the wood, and soon they were very busy.

It didn't take long.

"Wu, the wood is here!"

Maybe it's because the Huangqiu tribe currently has a lot of wood reserves, so it's easier to find, but the thirty pieces of wood that Shen Nong asked for were sent by the clansmen first.

Shen Nong didn't bother to waste time, and directly commanded them on the spot: "You put these pieces of wood in the form of two or two groups, two by two, cross them together to form a 'well' shape, yes! That's right, that's right, and then use this method of stacking weights to keep stacking them." ”

Seeing that the clansmen correctly implemented their intentions, Shen Nong couldn't help but nodded with satisfaction, the wooden tower stacked by the tic-tac-toe structure has a very strong bearing capacity, if the wooden tower is filled with soil again, then the wooden tower will be more solid, and at the same time, it is heavy, and it is not easy to be moved.

Around the wooden tower, Shen Nong chose to use dirt to form a slope, so that he and others could push one end of the trunk up the wooden tower along the slope, so that the trunk formed an oblique angle, and then everyone could use this angle to push the entire trunk into the ravine.

The two pieces of wood that were previously placed above the ravines can now be fixed, so that the trunks inserted into the ravines will not tip over and skew, so that the whole thing can be kept straight.

Soon, the three-board cart of soil was transported, and Shen Nong's idea was officially implemented.
