Fortunately it was autumn when the foundation was excavated and the weather was dry and there was no rain.
If it were earlier, in the summer, not to mention the inconvenience of being outside during thunderstorms, the newly dug tunnel would be full of water, making it difficult to start construction.
"Witch, what should we do next?" Yan Hu asked.
None of them had any experience in building walls, and everything needed Yang Cheng's guidance.
Yang Cheng pointed to the two corners of the tunnel and said: "First lay foundations in these two places, um... just insert a piece of wood!"
The principle of two points forming a line is known to all humans who have attended elementary school on earth.
In the process of building walls, generally speaking, the corners of the wall are the most important.
We must first determine where the endpoints of the corners are, so that when the wall is built, the three walls will not be independent of each other and cannot be connected at all.
"okay!"
Yan Hu responded and walked to the corner holding a tree trunk that was about 1.5 meters thick and more than 4 meters long after the branches were pruned.
"Come and lend a hand and hold the tree trunk!"
Yanhu lowered the tree trunk in the tunnel and shouted to the spear next to him.
When the spear came forward to hold the tree trunk, Yanhu released his hand and picked up a huge boulder from the ground.
"Roar!"
Yanhu roared and jumped nearly two meters high, just as his body was parallel to the tree trunk. Then he slammed the stone he raised high on the top of the tree trunk.
"Boom!"
Under the huge force of Yanhu, the tree trunk was driven directly into the soil about forty centimeters deep, and the nearby ground was shaking as a result!
Seeing this, Yang Cheng took a breath of cold air.
Damn it!
So exciting!
With a single hammer blow of a stone, a tall tree measuring 1.5 meters thick was hammered into a depth of 40 centimeters, which is nearly half a meter!
On earth, let alone human beings, even a light pile driver cannot sink a wooden pile into the soil so deeply in one go.
However, Yang Cheng was surprised, but the others took it for granted. They all clapped and cheered when they saw this.
"Yanhu, let me try." Cangshi said.
"OK."
Yanhu threw the stone to Cangshi. The big stone weighing several dozen kilograms seemed to have no weight.
Cang Shi didn't put any effort at all, he just caught it with one hand.
After receiving the stone, Cangshi took two steps, jumped to the same height as Yan Hu just now, and then smashed the stone down on the top of the wood.
"Boom!"
There was another loud noise, and the wooden pile sank another twenty-five centimeters.
"Hey, no, Cangshi, why are you so short? You're much worse than Yanhu!" Danya next to him laughed.
Cangshi was also a little confused, but turned around and said angrily: "Duan Ya, why don't you come?"
"I'll do it, I'll do it."
Short Tooth took the stone, jumped lightly, and smashed it hard on the top of the wooden pile.
"Boom!"
After a loud noise, the wooden pile only dropped five centimeters.
"this……"
Short Ya's face suddenly became a little embarrassed. The depth he hit was far less than Cang Shi!
Cang Shi didn't laugh at him. He was puzzled and turned to Yang Cheng and asked: "Witch, what's going on?"
Of course Yang Cheng knew what was going on.
Soil density and firmness.
"This is because the soil further down is much denser and more compacted than on the surface." Yang Cheng explained briefly.
density? Degree of compaction?
What is this?
Wu is saying something incomprehensible again...
Not only Cangshi, but also others were confused when they heard these two professional terms.
Yang Cheng did not continue to explain. It would be more troublesome to continue explaining. The primitive people still couldn't understand.
But one good thing about primitive people is that if they don’t understand something, they don’t understand it, so they simply don’t think about it.
And after hearing Yang Cheng say that the harder he hit it, the harder it got, so everyone became more interested in challenging it.
"Hey, let me do it. I want to try it and see how hard it is to hit!"
Yanhu said, spitting into the palm of his hand, took the boulder from Short Tooth's hand, and with a flash of the totem power in his chest, he slammed it down on the top of the wooden pile.
"Boom!"
A louder sound sounded than the previous ones, and the wooden pile sank another twenty centimeters!
"Hey, it's just that little, it's really hard to smash!"
Yanhu shook his arm that was shaken by the knocking. Looking at the wooden pile that had only sunk twenty centimeters, he was a little unconvinced and wanted to continue smashing it.
However, Yang Cheng called out to him: "Okay, Yan Hu, please stop, it's almost done!"
Before letting everyone smash the wooden pile, Yang Cheng drew a line and marked it on the now-whipped wooden pile. The mark was about one meter away from the bottom of the wooden pile. Now the mark was almost in the soil.
Yan Hu touched the back of his head and said with a smile: "Hey, Wu, it's really hard to smash this wooden stake. It took a few hits and the power of the totem exploded before it hit the line you drew."
Yang Cheng was speechless. Do you call this a bit strenuous?
These three or four blows were enough to penetrate one meter. If anyone on earth could smash a 1.5-meter-thick wooden pile into a depth of one meter in three or four blows, the contractor would be crazy with joy!
But then again, this is a good thing!
The totem warriors are so powerful that the completion date of the wall can be moved forward.
"Okay, since Yanhu you said it's a bit laborious, I'll teach you an effortless method."
Yang Cheng asked people to find five or six tree trunks that were relatively thinner than wooden stakes, and used a stone ax to sharpen one end of them as much as possible to serve as a "drill."
Then he slightly divided the totem warriors into teams.
The ninth- and eighth-grade totem warriors are responsible for taking the drill and smashing it down at the selected location. After hitting it to a certain extent, they shake the drill back and forth, pull it out, and then put it back into the hole and continue smashing.
This is to prevent the nail from being nailed too deep and not being able to be pulled out.
After pulling it out, smash it into the hole.
Repeat this until the thirty-centimeter mark carved on the drill is parallel to the ground, and the drill is pulled out to be considered complete.
Then there is the matter of the seventh- and sixth-grade totem warriors.
After being nailed to the ground with a drill, a hole will be left in place. Yanhu and the others later took a 1.5-meter-thick flat wooden stake. Not only did they easily find and align the hole, but they also used stones to drill down Smashing it takes much less effort than smashing it down directly.
Another advantage is that because the holes left by the original drill were relatively thin, and the wooden stakes in Yanhu's hands were very thick, after smashing the stakes in, they would not become loose or unstable at all.
For these piles, Yang Cheng gave them a one-meter-long wooden stick and asked them to nail down every other wooden stick.
At the corner of the wall, considering that the soil is not easy to build up in this place, the wooden piles are more densely nailed, almost wooden piles right after the wooden piles.
