If Ye Qiong wanted to measure the specific altitude of the tribe, Ye Qiong really had no choice. After all, he had never seen the sea before when Ye Qiong came to Xuexing.
Not to mention the sea level thing.
At present, the altitude is indeed of no practical significance, but the altitude difference between the city walls is!
Simply put...
It's a trigonometric function problem.
That is, the Pythagorean theorem, which draws three pounds and four proofs and five, thereby deducing the specific fall of the ground under the city wall.
If the city wall is not built, it may be more troublesome to measure, but with a seven-meter-high city wall as a reference object, Ye Qiong has a way to measure the drop of the four corners of the stone wall.
After taking a wooden ruler with a scale, Ye Qiong changed his clothes, put on a straw hat and raincoat and went out.
In the light rainy weather, the sight will still be affected, but Ye Qiong didn't plan to get things done in one day. Now, I will first measure the data on the four walls, such as the specific height of the wall.
I took the wooden ruler and came to the southeast corner first. At this moment, Rongling was still having a headache about how to get out the water that had accumulated into a small lake.
Ye Qiong came to Rongling with a wooden ruler.
Looking at the 'magnificent' scene in front of me, I was a little amused and crying...
Design error!
Fortunately, it can still be remedied, and water supply and drainage still need to be practiced before conclusions can be drawn.
"Uncle Rong, how about it? Are you clueless..." Ye Qiong clamped the wooden ruler into his armpit, then touched a piece of dried meat from his pocket and said.
Rongling looked at the small lake in front of him and sighed and said, "Oh... it's not easy to do. After three days of heavy rain, the terrain here is the lowest. I asked the soldiers to scoop out some of them with wooden barrels, according to the current ones.
I guess it will take half a year to finish the speed.”
"A drop in the bucket..." Ye Qiong used four words to describe it.
He stuffed the jerky meat in his hand into his mouth, then applied oil on his body and said, "Let's do it first."
Ye Qiong himself couldn't think of any good idea. The thickness of the bottom of the city wall was more than ten meters, so it was impossible to penetrate it. It would be fine to dig a hole from the bottom, but the inner test of the city wall was flooded, and the soldiers
There is no diving equipment.
It is not realistic to dig out from outside the city wall, because it is also flooded outside...
It's just not as high as inside. The water depth inside the city wall is about six meters, the diameter is about five hundred meters, and the size of more than a dozen football fields. If the tribe has a boat, it can be opened on it.
Looking at the large pond that was a bit endless, Ye Qiong could only temporarily place his hopes on God and quickly let out the sun to burn, which was much more reliable than the soldiers using wooden barrels.
In order to prevent the water from flooding the surface of the city wall too deep and causing irreparable losses, Ye Qiong did not stop Rongling and asked the soldiers to use wooden barrels to carry water outside, just as doing it as exercise.
As long as there are too many people, it will affect the construction of urban defense.
If you discharge the accumulated water that cannot be discharged, you have to wait until the moat outside is dug out, and it is estimated that it will be able to clear it in one go.
By then, the city walls at the southeast corner will be re-reinforced, after all, the clay soil is still not resistant to corrosion by cement.
What's more, it's no longer corrosion, but soaking.
So after a while, Ye Qiong himself could not think about what the city wall in the southeast corner would be soaked.
Anyway, the worst plan is to strengthen a layer, which is unlikely to collapse. The foundation below is very deep and very stable.
It’s useless to worry about this place now. There is nothing we can do about natural disasters and man-made disasters.
Ye Qiong instructed Rongling to ask the soldiers to do something else, so that they could organize the idle women and young women in the tribe who were still unmoved, and when the weather cleared, they would come over to exercise their muscles and bones.
Rongling nodded and agreed. Ye Qiong walked from the southeast corner city wall. When he arrived at the north wall, Ye Qiong turned over and climbed up, calling two soldiers to come and help, mainly to help him throw the rope from below and then
Fixed.
First use a rope to compare the height of the city wall, and then measure the rope. It's simpler.
After working hard for more than four hours, he finally measured the heights of most of the city walls. Ye Qiong directly used a dagger to carve it in a conspicuous position on the wall.
This data will definitely have other uses in the future.
While carving it on the wall, Ye Qiong also brought out a thinner animal skin and recorded a copy on it with an ink pen.
The current paper on Xuexing is this kind of animal skin, which is very luxurious. Some tribes will directly cook these animal skins when food is severely scarce in the late winter, so there are many people on Xuexing.
Things passed down are wasted...
After measuring the height of the city wall, we will build a tower about twice the height of the city wall at the center of the four walls.
After the construction of the tower is completed, the trigonometric function can calculate the terrain drop around the city wall and start digging, with the purpose of making the bottom of the moat at the same level.
If the gap is too large, there is no way to get the water.
Building a high tower requires a lot of wood. There are no forests around the Yeqiong tribe, only some sparse trees, not tall, and it is a bit difficult to cut them back and burn them.
Waste of manpower and material resources.
so……
Ye Qiong could only think of the dense forests in the south, and originally planned to build a timber base there.
Before, he was driven back because of the ancient forest ape and Qingning. Now Ye Qiong knew that there were no tribes in the dense forest, but the ancient forest ape, he had the idea of rebuilding a timber base.
After all, I have already had a deal. The last time I saw Qingzhi's relationship with those ancient forest apes seemed very harmonious. Although I couldn't tell whether it was a partner or a master or servant relationship, Ye Qiong went to make some wood, Qingzhi and those ancient forest apes
Ape, I guess I have to give you some face.
Although historical records show that forest apes love peace and have a strong sense of territory, forests are homes for them. If trees are cut down, they have nothing to do with caring for the environment, but they destroy their homes.
Therefore, when the ancient ape in the forest meets the human beings who break into the forest, they will find ways to drive them out as peacefully as possible.
For example, the last time Ye Qiong and those soldiers...
In the dense forest, rainy days are the most difficult, so Ye Qiong did not rush to go there, but was preparing to wait until the sky clears before going over and take a look.
By the way, let’s see what happened to Qingzhi’s grandfather and how many of the ancient apes in the forest are left.
Ye Qiong really wanted to bring those ancient forest apes back to the tribe.
The monster that can shoot two powerful arrows is so intelligent. If it can be used well, it will definitely be a force that cannot be ignored.
After returning to the room, Ye Qiong saw Tang Ying, who was carrying a pot of stuff on the stone table.
"I'm back, hurry up, I've cooked you for food, guess what..."
