After arriving at the answer of eighty centimeters in diameter, Zhang Yanhang began to work backwards based on the diameter, and found that when the length of the original hematite pillar reached two meters, the volume was exactly equal to one cubic meter.
The reason why Zhang Yanhang calculated the volume of the original hematite pillar was mainly to avoid wasting the grid space. After all, the upper limit of the volume of each grid is one cubic meter, so for higher efficiency, it must be filled with all the cubic meters.
.
"In that case, let's set the length of each raw hematite pillar to forty meters. In this way, the volume of each raw hematite pillar will be exactly twenty cubic meters. My storage box will be +3
There are a total of 800 grids, enough to hold forty stone pillars in a row, which means that a distance of 1,600 meters can be excavated at one time.
One thousand six hundred meters... It still feels a bit short... Maybe I can simply organize the grid of my belt bag and I should be able to free up some space."
Zhang Yanhang began to count his pockets as he spoke. He now has a total of four pockets + 4, one pocket pack + 3, one pocket pack + 2, one pocket pack + 1 and two ordinary pockets.
"Huh? It seems that you can synthesize a new belt bag +4?"
Zhang Yanhang remembered that the two separate ordinary pockets seemed to have been obtained from the zombie police in the third prize pool of the slot machine when he completely emptied Raccoon City last time, but at that time he was in a hurry to sort out the items in the ashes treasure chest and did not bother to do so.
Fusion.
After Zhang Yanhang briefly recalled it, he immediately started alchemy and began to fuse the pocket + 4. With the activation of the alchemy circle, the five pockets with different fusion times inside it quickly began to melt and fuse in sequence.
.
After wasting a little time, a brand new fanny pack +4 appeared in front of Zhang Yanhang, "Including this newly fused fanny pack +4, I now have a total of five fanny packs +4. According to each fanny pack +4, there are thirty-two.
In terms of grids, there are a total of one hundred and sixty grids...
If we sort out the contents of each pocket compartment, we can at least take out a hundred more compartments to hold hematite pillars."
"After I finish sorting out the grid of my pocket, the preliminary preparation work will be completely completed. The only thing I need to do after that is to continue digging out the hematite raw stone pillars." Zhang Yanhang sighed silently, and then began to show no expression.
Organizing grid fields.
After sorting out all the grids, Zhang Yanhang found that the situation was better than he expected. All the things combined could only fit forty grids. In other words, Zhang Yanhang had one more grid during the process of digging the passage.
There are one hundred and twenty usable grids, and there are now a total of nine hundred and twenty grids.
"Nine hundred and twenty grids can accommodate forty-six hematite raw stone pillars with a length of 40 meters. Therefore, every time I excavate a distance of 1840 meters, I have to make a round trip to clear the grid columns before I can continue digging.
Calculated based on the depth of the passage of 77 kilometers, I need to make a total of forty-two round trips.
Forget it, let’s not think about these things and start digging directly. We still need to practice the specific data to get the answer.”
Zhang Yanhang sighed silently again, feeling sad for the boring work ahead.
…………
October 19th, the eleventh day after the Mid-Autumn Festival and National Day holidays, and also the fifth day after Zhang Yanhang left the main world, at ten o'clock in the evening, hematite veins, vertical tunnels, and an underground depth of 72 kilometers.
At this time, Zhang Yanhang was expressionlessly climbing up a hematite chain quickly. Perhaps because he had already relied on this thing for dozens of times, Zhang Yanhang's movements looked particularly flexible and skillful.
That's right, because a vertical tunnel with a diameter of only 80 centimeters is really not a convenient scene for movement, so Zhang Yanhang made a hematite chain to use it to and from the bottom of the tunnel and the inner area of the small hematite ant nest Daragu.
With the increase in depth, although Zhang Yanhang has become particularly skilled in climbing chains, it still takes him nearly an hour to climb up more than 70 kilometers. Of course, it is faster when he comes down, as long as he goes all the way
Just let it fall naturally.
According to relevant physical formulas, when an object falls naturally, it will experience a fixed acceleration based on time. To put it simply, the higher the height of the fall, the faster it will eventually fall. There is no upper limit for the overall acceleration.
Theoretically speaking, as long as the distance is long enough, the continuously superimposed falling speed can even exceed the speed of light, but the premise is that the accelerated object can withstand this speed without disintegrating. Therefore, exceeding the speed of light is just a theory after all.
Taking the more than 70-kilometer vertical tunnel dug by Zhang Yanhang as an example, his falling speed is more than ten times faster than climbing.
Of course, due to air resistance, Zhang Yanhang's actual speed when he first fell was only ten meters per second. Therefore, he usually used a spiritual energy acceleration in the initial stage to achieve a faster superposition of speed.
But what I have to admit is that although Zhang Yanhang's physical attributes have reached the second-level limit of fifty points, and he also has an indestructible golden body
Being thrown directly to death, after all, the length of more than 70 kilometers is really terrifying.
Therefore, although the acceleration of falling is indeed a good thing and can help Zhang Yanhang reach the bottom quickly, he will actually slow down from time to time to prevent him from actually falling to death.
The specific method is that Zhang Yanhang instantly expands the energy shield, blocks himself directly in the center of the channel to offset the acceleration, and then starts free fall again. This step usually only needs to be repeated several times before he can successfully reach the bottom of the channel.
, the whole process only takes a few minutes at most.
By the way, because of this acceleration, Zhang Yanhang experienced the speed of sound in advance during the fall. How can I say it, it is indeed quite good.
But compared to this kind of passive sonic movement that cannot change posture at all, Zhang Yanhang hopes that he can actively move at sonic speed in the future.
According to Zhang Yanhang's estimation, he should be able to move at the speed of sound as long as he is promoted to the third level at least. By then, he will be able to passively learn the skill of Sonic Punch without any teacher. Although the Sonic Punch in Pokémon
It should be different from his definition of sonic punch, but it's not a big problem.
