Lord of Ashes

Genius remembers this site address in one second: [] The fastest update! No ads! After getting the answer of 80 cm diameter, Zhang Yanhang began to reverse the diameter based on the diameter, and found that when the length of the original stone pillar of hematite reached two meters, the volume was exactly equal to one cubic meter.

The reason why Zhang Yanhang calculates the volume of the original stone pillars of hematite is mainly to not waste the space of the grid. After all, the upper limit of the volume of each grid is one cubic meter, so for higher efficiency, it must be filled with the volume of this cubic meter. .

"If this is the case, let's set the length of each original hematite pillar at 40 meters. In this way, the volume of each original hematite pillar is exactly 20 cubic meters. My storage box + total There are 800 grids, enough to hold forty stone pillars continuously, which means that a distance of 1,600 meters can be excavated at once.

One thousand six hundred meters... It still feels a bit short... Maybe I can simply tidy up the grid of my pockets, and it should make some space. "

While talking, Zhang Yanhang began to count his pockets. He now has four pockets+, one pocket+, one pocket+, one pocket+ and two ordinary pockets.

"Huh? It seems that you can just synthesize a new waist bag+?"

Zhang Yanhang remembers that the two separate ordinary pockets seemed to have been obtained from the zombie police in the slot machine third prize pool when the raccoon city was completely emptied last time, but he did not care about it because he was eager to sort out the items in the ashes treasure chest. Fusion.

After a brief recollection, Zhang Yanhang immediately activated the alchemy and began the fusion of the waist-pack +. With the activation of the alchemy circle, the five waist-bags with different fusion times inside it quickly began to melt and merge in sequence.

After wasting a little time, Zhang Yanhang had a brand new waist bag+ in front of him. "Counting the waist bag that was just fused + I now have five waist bags+. If you calculate according to each waist bag + thirty-two grids. , A total of one hundred and sixty grids...

If you sort out the contents of the pockets, at least you can take out a hundred more grids to hold the original stone pillars of hematite. "

"After I finish finishing the grids of my pocket, even if the preliminary preparations are completely completed, the only thing that needs to be done afterwards is to persevere in the excavation of the original stone pillars of the red iron." Zhang Yanhang sighed silently, and then began to face blank expressions. Organize the grid column.

After finishing all the grids and columns, Zhang Yanhang found that the situation was better than he expected. All the things together contained only forty grids. In other words, Zhang Yanhang had one more grid in the process of digging the channel. One hundred and twenty available grids, now there are a total of nine hundred and twenty grids.

"Nine hundred and twenty grids can hold forty-six original stone pillars of forty meters in length. Therefore, every time I dig a distance of meters, I have to go back and forth and clear the grids before I can continue to excavate the channel. Calculated according to the depth of 77 kilometers, I need a total of forty-two round trips.

Forget it, don't think about these things, just start digging, the specific data still needs to be practiced to get the answer. "

Zhang Yanhang sighed silently again, feeling sad for the upcoming boring work.

…………

On the day of the month, the 11th day after the Mid-Autumn Festival and National Day holidays, it was also the fifth day 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 quickly climbed a red iron chain with no expression on his face. Perhaps because he had relied on this thing for dozens of times, Zhang Yanhang's movements seemed exceptionally flexible and skilled.

That's right, because the vertical tunnel with a diameter of only 80 centimeters is really not a convenient scene for moving, so Zhang Yanhang refined the hematite chain to travel between 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 exceptionally proficient in climbing chains, it takes him nearly an hour to climb more than seventy kilometers. Of course, it will be faster when he comes down, as long as he goes all the way. Just fall naturally.

According to related physical formulas, objects will have a fixed acceleration according to time when they fall naturally. In simple terms, the higher the height of the fall, the faster the final fall speed. The overall acceleration has no superimposed upper limit.

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, beyond the speed of light is only a theory after all.

In the case of the 70-kilometer vertical tunnel that Zhang Yanhang dug out, his falling speed is more than ten times faster than climbing.

Of course, due to air resistance, Zhang Yanhang's speed was only ten meters per second when he first fell. Therefore, he usually accelerates his aura in the initial stage to achieve a faster stacking speed.

But what I have to admit is that although Zhang Yanhang’s physique has reached the second-order limit of fifty points~www.novelmt.com~ and he still has a non-destructive golden body. However, if he is allowed to fall straight on. At the bottom of the passage, you will also be killed directly. After all, the length of more than seventy kilometers is really terrifying.

Therefore, although the acceleration of the fall is indeed a good thing, it can help Zhang Yanhang reach the bottom quickly, but he actually slows down from time to time to prevent him from falling to death.

The specific method is that Zhang Yanhang instantly expands the energy shield, jams himself directly in the center of the channel to offset the acceleration, and then restarts free fall. This step generally only needs to be repeated several times, and he can reach the bottom of the channel smoothly. , The whole process only takes a few minutes at most.

By the way, because of this acceleration, Zhang Yanhang experienced the speed of sonic movement in advance during the process of falling. How to say it, it is indeed quite good.

It's just that Zhang Yanhang hopes that he will be able to move at the speed of sound actively in the future, compared to this passive movement at the speed of sound, which is completely unable to change his posture.

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 rank. Then he can passively learn the skill of sonic fist without a teacher, although the sonic fist in Pokémon It should be different from his definition of sonic boxing, but the problem is not big.
