If Ye Qiong were to ask Ye Qiong to measure the specific altitude of the tribe, then Ye Qiong really had no choice. After all, he had never even seen the sea since Ye Qiong came to Snow Star.
Not to mention sea level.
At present, the altitude does not have any practical significance, but the altitude difference of the city wall does!
simply put……
It's a trigonometric function problem.
That is to say, the Pythagorean theorem, which combines three strands, four strands, and five strands, can deduce the specific fall of the ground under the city wall.
If there is no city wall built, it may be more troublesome to measure, but with the seven-meter-high city wall as a reference, Ye Qiong can measure the height difference at the four corners of the stone city wall.
After taking out a graduated wooden ruler, Ye Qiong changed his clothes, put on his bamboo hat and raincoat and went out.
In light rain, the line of sight will be affected to some extent, but Ye Qiong doesn't plan to finish the matter in one day. Now, he will first measure some data on the four walls, such as the specific height of the wall.
Taking the wooden ruler, he first came to the southeast corner. At this moment, Ronling was still having a headache about how to get out the water that had accumulated into a small lake.
Ye Qiong came to Ronling with a wooden ruler.
Looking at the 'spectacular' scene in front of me, I felt a bit dumbfounded...
Design error!
Fortunately, it can be remedied, but water supply and drainage still need to be practiced before we can draw a conclusion.
"Uncle Rong, how are you? Do you have any clues..." Ye Qiong put the wooden ruler in his armpit, then took out a piece of dried meat from his pocket and said.
Ronling looked at the small lake in front of him, sighed and said: "Oh...it's not easy to deal with. After three days of heavy rain, the terrain here is the lowest. I asked the soldiers to scoop some out with wooden buckets. According to the current situation, Given the speed, I estimate it will take half a year to complete."
"A drop in the bucket..." Ye Qiong used four words to describe it.
He stuffed the dried meat in his hand into his mouth, then rubbed oil on his body and said, "Let's do it first."
Ye Qiong himself couldn't think of any good way. The thickness of the bottom of the city wall was more than ten meters. It was impossible to penetrate it. It was possible to dig a hole from the bottom, but the city wall was already flooded in the internal test. The soldiers There is no diving equipment.
Digging from outside the city wall is unrealistic because the outside is also flooded...
It's just not as high as the inside. The measured water depth inside the city wall is about six meters, the diameter is about 500 meters, and it is as big as a dozen football fields. If the tribe has a boat, it can be driven on it.
Looking at the seemingly endless large pond, Ye Qiong could only place his hope on God for the time being. He quickly went out to bask in the sun, which was much more reliable than the soldiers using wooden buckets.
In order to prevent the water from being too deep to flood the surface of the city wall and causing irreparable damage, Ye Qiong did not stop Ronngling and asked the soldiers to use wooden buckets to carry water outside, just to exercise.
As long as there are not too many people, it will not affect the city defense construction.
The stagnant water that cannot be drained will have to wait until the moat outside is dug out before it can be drained at once.
At that time, the city wall at the southeast corner will need to be re-reinforced. After all, clayey soil is still not as corrosion-resistant as cement.
What's more, now it's not corrosion, but immersion.
So after a while, when the water recedes, Ye Qiong himself can't even imagine how the southeast corner of the city wall will be soaked.
Anyway, the worst-case scenario is to reinforce the first floor. Collapse is unlikely. The foundation below is very deep and very stable.
There's no point worrying about this place now. There's no way to avoid natural and man-made disasters. There's nothing we can do about it.
Ye Qiong asked Ronling to ask the soldiers to do something else. They could organize the idle women, old and children in the tribe who had not moved yet, and let them come over to stretch their muscles when the weather cleared.
Ronling nodded in agreement, and Ye Qiong walked from the southeast corner of the city wall to the north side of the city wall. Ye Qiong turned over and climbed up, calling two soldiers to help him, mainly to help him throw the rope up from below. fix.
First use a rope to compare the height of the city wall, and then just measure the rope, it's easier.
After working for more than four hours, he finally measured the height of most of the city walls. Ye Qiong used a dagger to carve eye-catching locations on the wall.
There will definitely be other uses for this data in the future.
While carving on the wall, Ye Qiong also brought out a piece of thinner animal skin, and then wrote a copy on it with an ink pen.
The current paper on Snow Planet is this kind of animal skin, which is very luxurious. Some tribes will directly cook and eat these animal skins when food is seriously scarce in late winter. Therefore, there are many valuable materials on Snow Planet. What is passed down is wasted...
After measuring the height of the city wall, the next step is to build a tower that is about twice as high as the city wall at the center of the four walls.
After the construction of the tower is completed, Ye Qiong can calculate the terrain difference around the city wall through trigonometric functions, and then start digging. The purpose is to make the bottom of the moat at the same level.
If the gap is too big, there will be no way to pass water.
Building a tall tower requires a lot of wood. There are no forests around the Ye Qiong tribe, only some sparse trees. They are not very tall, and it is difficult to cut them down to make fire.
A waste of manpower and material resources.
so……
Ye Qiong could only think of the dense forests in the south, where he originally planned to build a timber base.
Previously, they were driven back because of the forest apes and Qing Ning. Now that Ye Qiong knows that there are no tribes in the dense forest, but forest apes, he has the idea of building a new timber base.
After all, they have already dealt with each other. The last time I saw the relationship between Qing Zhi and those ancient forest apes, they seemed to be very harmonious. Although it was not clear whether they were partners or masters and servants, Ye Qiong went over to get some wood, and Qing Zhi and those ancient forest apes seemed to be very harmonious. Ape, I guess I need to give him some face.
Although it is recorded in historical records that forest apes are peace-loving and have a strong sense of territory. The forest is their home for them. If trees are cut down, for them, it has nothing to do with caring for the environment, but destroys their home.
Therefore, when forest apes meet humans who break into the forest, they will try to drive them out as peacefully as possible.
Just like last time Ye Qiong and those soldiers...
In the dense forest, rainy days are the most difficult to endure, so Ye Qiong was not in a hurry to go there, but planned to wait for the weather to clear before going over to have a look.
By the way, let's take a look at what happened to Qingzhi's grandfather and how many forest apes are left.
Ye Qiong really wanted to get those forest apes back to the tribe.
A magical beast that can shoot two powerful arrows has such high intelligence. If it can be used properly, it is definitely a force that cannot be underestimated.
After returning to the room, Ye Qiong saw Tang Ying, who was carrying a pot of food and placing it on the stone table.
"I'm back. Come on, I made you something to eat. Guess what it is..."
