Chapter 339: Excavating a Passage

"Hey, shaking fists upside down and stamping feet to dig tunnels, this picture feels a bit too funny even if you think about it a little bit. So it's really not a wise decision to dig tunnels with fists all the way, so maybe I should find some other A method of digging a passage."

When it comes to other excavation methods, Zhang Yanhang immediately thought of the omnipotent alchemy. After all, if the situation here is solved by alchemy, it is indeed quite a professional counterpart.

"I used to estimate that it would take at least a few minutes or even more than ten minutes to use alchemy to penetrate the thick walls of hundreds of meters in the red iron ant nest, but if I think about it now, maybe I underestimated the alchemy at the beginning. Or maybe my way of using it is not right."

Zhang Yanhang’s previous method of penetrating the wall has always been to melt the wall directly and create a tunnel that is enough for him to pass through normally. But now, he feels that this method is a bit too laborious. In fact, he can fully cooperate with it. Pocket to do some more convenient digging methods.

For example, Zhang Yanhang can completely melt only the edge and bottom of the column that needs to be excavated. In this case, as long as the column and the whole wall form a simple separation, he can directly use the pocket to clean the entire column. Fake it.

If this method is indeed feasible, it is definitely more convenient and faster to melt only the edge than to melt the entire cylinder.

Compared with the method of completely melting and reshaping that Zhang Yanhang envisioned before, the new method he envisions now has fewer shaping steps, which will greatly reduce the time Zhang Yanhang needs to dig out the channel lock.

Moreover, in addition to saving a lot of time in shaping, the cylinders excavated by Zhang Yanhang's new method are smaller in volume.

Compared with digging a tunnel that is enough for Zhang Yanhang to walk and pass normally, the cylinder he dug out with this new method only needs a diameter of one meter in the most extreme case, as long as the entire passage can allow Zhang Yanhang to barely pass through. And turn around on it.

The reduction of the excavation diameter means that Zhang Yanhang can use the same time and the same energy value to excavate a longer distance, which will definitely save a lot of time for Zhang Yanhang to complete the final tunnel excavation.

After briefly thinking about the preliminary excavation plan, Zhang Yanhang began to carry out specific practice. Although the new method he envisioned seemed quite reliable, it still needs to be verified first whether it can really succeed.

Moreover, in addition to verifying whether it can be successful, Zhang Yanhang also needs to test the energy consumption of digging a tunnel with this method.

If there were a lot of them, it would be considered a success, but overall it was a failure. After all, the energy value was different from Zhang Yanhang's physical strength, and recovery was very slow.

Once Zhang Yanhang runs out of energy, it will take at least four hours to restore it to full capacity, but digging with fists is different. If he doesn't use the death wave skill and the skill of avoiding evil, Zhang Yanhang can at least do his best. Punches all day long before you need a break.

After all, in Zhang Yanhang's process of hunting monsters, skill consumption always accounts for the majority. Therefore, after removing the skill consumption, it will not be difficult for him to punch continuously all day and night with his mighty physical strength.

Zhang Yanhang simply picked up the gravel piled up beside him,

Then the alchemy was started directly.

With the injection of Zhang Yanhang's energy value, the alchemy circle quickly penetrated layer by layer, and soon spread out tens of meters away. When the alchemy circle reached the designated position, dozens of heavy alchemy circles along the way began to work at the same time , quickly melting the edge part of the cylinder and the bottom cross section.

It took about less than a minute for Zhang Yanhang to complete the overall cutting of the column, and successfully separated the contact surface between the column and the original red iron stone wall or hematite vein.

After successfully separating the pillar, Zhang Yanhang touched the surface of the pillar lightly with his hand, and a whole red iron original stone pillar with a length of tens of meters disappeared without a trace in an instant, and Zhang Yanhang successfully put it into his pocket.

"It's really feasible? If this is the case, then it's time to consider a formal excavation plan."

While talking, Zhang Yanhang got into the mini cave he just dug. The diameter of this cave is about one meter, and the length is almost fifty meters. Forty cubic meters of red iron original stone pillars have been excavated at one time.

This also means that just one original red iron stone pillar has already occupied forty grids in Zhang Yanhang's pocket.

"If each original red iron stone pillar maintains such a volume, then my grid slot will be filled up after half an hour of continuous excavation at most, so maybe I should try to reduce the overall volume of the original red iron stone pillar... ..."

For things like reducing the size, the length must not be an issue. Therefore, Zhang Yanhang can only reduce the diameter of the Chitieyuan stone pillar. He briefly moved his body in the mini cave, and the overall situation is indeed as he predicted before. As expected, the turn can be made while hugging the knees and curling the body.

"But anyway, there are no monsters along the way, so it doesn't really matter if you can turn around, and I won't need to turn around when I dig the tunnel down later, so I still use Chitieyuan Let’s reduce the diameter of the stone pillar a little bit.”

While talking, Zhang Yanhang began to use alchemy to simulate related scenes. He used the surrounding red iron rough stones to re-surround his body to form a vertical wall, and began to shorten the diameter of this small space step by step. Finally, he obtained The limiting diameter is sixty-seven centimeters.

Zhang Yanhang can barely sit on the ground while maintaining this level, but in terms of comfort, 80 cm is more suitable, so that he can barely stretch his legs and not maintain the same posture the whole time.

"Since this is the case, let's choose 80 centimeters. Although the diameter is only shortened by 20 centimeters, the volume has actually been reduced by a considerable part."

Zhang Yanhang simply calculated according to the cylinder volume formula. The total volume of the original red iron stone pillar with a diameter of 1 meter and a length of 50 meters is about 40 cubic meters, but the original stone pillar of red iron with a diameter of 80 centimeters and a length of 50 meters is the same. The total volume is only twenty-five cubic meters, which means that the total volume has been reduced by more than a third.
