The depth of the magic well was a very unexpected situation for Wang Qi.
In the history related to the Fountain of Youth, there is no mention of what the surface and underground parts of the magic well look like. There is only one name. After arriving at the scene, judging from the crater-like terrain, it was also a surface explosion that occurred.
It turns out there really is a bottomless well.
The diameter is 30 meters, the depth is more than 1.6 kilometers, and the total rock engineering volume exceeds one million cubic meters.
Magic can do many magical things, but there is no way to stuff a million cubic rocks into the cracks in the nearby rock formations. Most of them still have to be lifted to the wellhead for discharge. Even if a team of magicians does it, the amount of work is not small.
Of course, if you really think about it, even if there is another ten kilometers deep inside the well, the total earthwork volume is about the same as a single-span cable-stayed bridge of more than 1,000 meters. The concrete piers for fixing the cables are two to three million square meters. A lump.
The size of the well itself was not what attracted Wang Qi. What he cared about was the higher density of magic power below.
Starting from the needs, I came to the main world specially, but I didn't see the so-called God, let alone God, I couldn't even see any miracles.
... Although the defense line established by the Church of Nature in the late Lei Ming period was large enough, it was not very impressive in itself. It was only possible to build it by delaying the time of the soldiers and civilians at the front.
Based on this situation, it is speculated that God may not end directly, but use the descending body to participate in the war.
But if they don’t come to an end, how can they decipher the relationship between God and the will of the world? Without this link, how can we directly fast forward to communicating the will of the world?
Through in-depth study of the phenomenon and principles of magic particles, it is not completely hopeless, but this kind of research involving the nature of the world, given the current size of the kingdom, it is difficult to give a clear timetable.
If there are no more lines to choose from, it is best not to miss the basic data that can be collected.
When the penal colony was transformed into a floating island, a high-precision magic power concentration counter had not yet been developed, so the opportunity to collect basic data was missed. By the time the equipment was available, magic power abnormalities could no longer be detected.
According to this result, the "rock surface concentration" of magic should not remain above the mean value for a long time.
However, it is not yet certain whether the location is special, some functions of the magic well are still functioning, or there are other reasons. Wang Qi temporarily wanted to investigate more thoroughly, which may be helpful for subsequent research work.
First, assign homework for students to discuss methods of collecting underground data.
He didn't read it at all. When he returned to the camp, he took out the big book and started designing seeds.
Looking at it now, with the students from the Fountain of Youth, the risk of conflict has been reduced. The second seed prepared for the main world trip should not be used, so we might as well change it for this scientific research.
The seeds of the sacred tree cannot be created out of thin air. At most, their development speed is "100 million" points faster.
There is a newly developed soil layer under the snow line within the Magic Well Crater, but the overall quality is not very good.
There are two forms of soil formation: humus accumulation brought about by high-level plant replacement, and mainly formed by dust accumulation plus lichen and a small amount of herb replacement.
Three thousand years after the incident of the Magic Well, the humus-accumulated soil could have increased to a depth of twenty or thirty meters during this time. However, the pit of the Magic Well should have directly exposed the rock formations, so we could only start with lichens. In addition, there is snow in the local area in winter. The replacement efficiency is low and it is difficult to accumulate enough nutrients to supply advanced plants.
In a word, there is nothing in the pit that can be used as a source of nutrition for the development of the sacred tree.
The transportation itself from outside the pit to inside is not difficult. The slope is about 7/1000, which is enough for the sled to go down automatically. The human only has to be responsible for getting the empty car back.
The problem is to rely on manpower to collect dead leaves and other things under the snow. Not to mention whether the human body and magic power can keep up, and the efficiency cannot keep up. How long will it take to gather the resources needed for the sacred tree to penetrate one thousand meters underwater? ?
It is still necessary to let the sacred tree be self-sufficient, collect nutrients from the outside to grow, and go into the water across a distance of more than ten kilometers.
With the nutrient call strategy of the giant sacred tree as the basis, this exploration task can be grown close to the ground without considering the problem of mass collapse. Small seeds can fully undertake the task.
There are also problems.
What kind of environment is it like one thousand meters, two thousand meters, three thousand meters underwater? Can the same strategy cope with changes in temperature and pressure at various depths?
Wang Qi has never been exposed to such in-depth engineering, but now, let alone making machinery, the response of bioengineering is simpler. One word can describe the solution: soft.
Just like deep-water fish, the softness itself protects them from damage caused by water pressure.
This has a certain conflict with the wooden body of the sacred tree, but it is not a big problem. Changing the cell wall to a cell membrane does not require long-term work and short-term coping. It will naturally disintegrate later without worrying about anything.
The focus is still on how the sacred tree obtains the data Wang Qi wants.
It would be great for people to go down and observe and collect directly, but under the existing conditions, a diving bell cannot handle it.
Wang Qi had a little knowledge of mechanical structures. He could use the sacred tree to extract water-soluble metal salts, then make a temporary furnace and use magic to get some metals. It would not be a big problem to make a makeshift diving bell.
However, the depth of the well bottom and the water pressure are ten times or more than those within two hundred meters. Even if the titanium alloy can be refined on the spot, the precision error of pure manual work will lead to huge accident risks.
In addition, the biggest problem with the diving bell solution is human endurance.
Referring to the underwater business related to offshore oil wells that I happened to learn about in my previous life, it takes more than three days for a one-way trip up or down in water depths exceeding one thousand meters. The human body must gradually adapt to the air pressure corresponding to the water pressure before entering the water or leaving the cabin. Otherwise, once the pressure An out-of-control human body can explode at any time. Wang Qi and Li Xiang have slightly higher physical fitness, but after all, neither of them has broken away from the category of material creatures at this stage. He does not want to use himself as experimental material to see if he can speed up the process.
If the sacred tree collects data by itself, the organ types will be more complicated and it will be difficult to obtain samples, but at least it will be more controllable.
One night later, before the drawings were finished, I took a look at the plans discussed by the students.
It's nothing more than magic.
Wang Qi did not directly deny it and took them to the small lake again.
Using a 7x7 1.5mm steel wire rope, he tied it to a piece of dead wood found under the snow, hung a stone from it, and Li Xiangfei flew to the center of the lake to open a hole and set out the line.
Previously, the bandits were tied up with 7x19 strands of 6 mm diameter steel wire rope, which weighed 15 kilograms per 100 meters. There were only two rolls in total, which was not enough to tie together.
The 6mm one is considered a survival tool, while the 1.5mm one is for daily use, such as fishing, making small animal traps, repairing carriages, etc. You will cut off a section.
Its reasonable lifting weight is 30 kilograms, and its breaking force is more than 150 kilograms. You don’t have to worry even if it is lowered for a thousand meters... By the way, this roll is two thousand meters long in my hand. I use some intermittently on the road, mainly wood. The made carriage wheels often require tossing, and now they are still 1,300 meters long.
Li wanted to lower the line to the remaining point and return to the lake while driving through the ice, making sure that the entire wire rope was under the ice.
After half an hour, pull the rope up again.
When he saw the wood, the student's expression turned bad.
This dry log was soaked in water for a while. Not only did it not become larger, it actually became smaller, at least a quarter smaller than before it was put into the water!
"If there is a longer line, the effect will be more obvious." Wang Qi took out the magic plan written by the students, "So you can't go into the water, people can't withstand it."
