After a while, Wang Du recovered his seven, seven, eight, eight, eight

It turns out that all the inside of the pit has no support points, because people feel that the inner wall of the pit is hard enough, and there is no awareness of this, so there are no load-bearing pillars to support the inside of the pit.

Originally, this point is estimated to be correct, the passage of this pit is indeed hard enough, even if it is dug to a depth of 10,000 meters, it is impossible for it to collapse, but there is a prerequisite, that is, not to cause resonance in the process of excavation.

Wang Du looked at dozens of pits that were being excavated, and he found that the mining method of the Starry Sky Mine was very ancient, that is, the true element was injected into special mining tools, and then the hard ore was chiseled down little by little.

You must know that these mining people are not ordinary people, their minimum cultivation is also in the Immortal King Realm, and there are even hundreds of people who are strong in the Immortal King Realm.

These people are mining under the pit together with urging the true yuan, which is an extremely destructive behavior. In addition, different types of ores are closely related to each other, and there is a clear separation between the ore layers and the ore layers.

Depending on the type of ore, its density, mass, weight, hardness, conductivity, etc. are different. Then, by a fortuitous coincidence, dozens of miners used the extremely destructive True Yuan to mine at the same time, which triggered the resonance of the same ore layer, and under the action of resonance, these originally hard mines were directly broken from the inside, thus causing the collapse.

The so-called extreme must be reversed, hard to the extreme, its toughness will inevitably be reduced, toughness is not enough, once there is resonance, then the entire mine will avoid a large area of broken, collapse will also appear.

Listening to Wang Du's eloquent words, Hanhai Emperor Yu Canghai seemed to understand whether he understood or not, and he said:

"According to the meaning of the hall master, the reason for the frequent collapses is precisely because this starry sky mine is too hard, because it is extremely hard, but it makes it brittle?"

Wang Du nodded lightly, this is probably what he was going to say, as for what resonance is, although it was the first time he heard this term, he could still roughly understand its meaning.

It's like a superposition of power, and under a perfect superposition, one plus one will produce a result that is far greater than two.

"Is there a way for the hall master to solve this problem?"

Hanhai Emperor Yu Canghai's eyes were full of hope.

"Yes, and it's easy. ”

The way to reduce resonance is simple, it is to change the frequency, as long as the frequency does not use resonance, it will not happen.

In the future, when mining, the Immortal King and the Immortal King are mixed, and the strength is fierce and the strength is feminine, so that the resonance can be eliminated.

"It's so easy, and it only takes one change in staffing?"

Hanhai Emperor Yu Canghai was skeptical, he thought that this solution would be very difficult, but it turned out to be so simple.

In order to speed up the mining of ore, the first person in charge of the Starry Sky Mine set the rule, and people with similar strength attributes were in the same pit, because he thought that this would work with each other more quickly.

As a result, when I heard Wang Du say this today, it was precisely in this way that the hidden danger of collapse was buried.

"Of course, how hard else would it be?"

Wang Du patiently gave an example to Hanhai Emperor Yu Canghai, saying that he imagined the ore as a strong enemy, and the miners who mined as all kinds of true elements.

So is it easier for those with the same true elements and similar strength attributes to soften together, thus forming a more destructive attack?

Hanhai Emperor Jun Yu Canghai listened to Wang Du sleep like this, and instantly understood what Wang Du meant, that is, because the strength attributes of the people in the same pit were too similar, it produced an unexpected destructive force and caused the collapse.

This was originally a good thing, but mining in a pit turned out to be a bad thing.

"Of course, just in case, when mining in the future, a formation should be carved at certain distances to reduce the risk of collapse. ”

Wang Du already had an idea, but he couldn't do it himself, because he didn't know how to depict these formations.

Hanhai Emperor Jun Yu Canghai nodded again and again, as long as it can be mined safely and efficiently, Wang Du will do whatever he wants.

Wang Du said his idea, he needs someone who understands the formation to portray a formation that absorbs sound and energy, and at the same time, this formation can also transmit the absorbed energy.

Didn't the Hanhai Emperor Jade Canghai say that this starry sky mine cannot be used for space shuttle.

If you can't travel through space, the speed of transporting minerals will be reduced, so Wang Du has to build a conveyor belt, and use the energy collected by these formations as the power of the conveyor belt, and send the excavated ores to the surface in a steady stream.

Of course, a storage ring is a good choice, but these people are all criminals, and their things have been confiscated a long time ago, so where is the storage ring?

Just four counts, each person will be reissued with a storage ring, but do you have to look through them every time you collect them to see if they are hiding secrets?

Therefore, the method that the Star Mine has been using is to dig up the ore and pick it up from below.

Although these ores are heavy, they are not too much of a burden for these immortal kings and immortals, and they are just a matter of running a few times.

Later, with the conveyor belt, the excavated ore was directly placed on the conveyor belt, and they were automatically sent to the surface by the conveyor belt, and only a few people on the ground needed to take turns to select useful ores.

After listening to Wang Du's design, Hanhai Emperor Yu Canghai's eyes were full of joy, if all these things were realized, then the ore production of the Starry Sky Mine would definitely increase greatly!

"Your Excellency has really been of great help!"

Hanhai Emperor Yu Canghai bowed his hand to Wang Du, and then bowed slightly, this bow was not because of Wang Du's identity, but Hanhai Emperor Yu Canghai's inner thanks!

"The Emperor of Hanhai is serious, I am also a creature of this universe, so I naturally have the responsibility to contribute my own strength to this universe, and I have another proposal. I need the Hanhai Emperor to build some buildings in this Starry Sky Mine, this place is rich in resources and is very suitable for researching something, if it comes to fruition, it will be something that can greatly improve our combat power!"

Wang Du had an idea in his heart a long time ago, he wanted to combine modern weapons with cultivation spells, but it was delayed again and again for various reasons, and he had let the public infusion refining once or twice before, but because he didn't participate in the public infusion refining himself, the things he got were not satisfactory.

Today he saw the Starry Sky Mine, this place is rich in mineral resources, it is very convenient to refine weapons on a large scale here or research new things, and now there is no trivial matter, he can also devote himself to research.

Hanhai Emperor Yu Canghai was a little hesitant when he heard Wang Du say this, because he couldn't be the master of this matter, the Starry Sky Mine was in charge of ten emperors, and if he wanted to build something else in the Starry Sky Mine, he couldn't be the master alone.

Wang Du naturally saw the reason for the hesitation of Hanhai Emperor Yu Canghai, so he said:

"Emperor Hanhai doesn't need to worry too much, my eldest brother will pass on the order tomorrow at the latest, and then there will be no need to embarrass Emperor Hanhai. ”

Hanhai Emperor Yu Canghai suddenly remembered what Zhongli Yunkong said, this was his too much worry, as the sworn brother of the Supreme Immortal Emperor, it was naturally not a problem for him to want to get something in the Starry Sky Mine.

"This is my Yucanghai confused, as the hall master, the ten emperors naturally have no reason to object, and the hall lord is still to increase the combat effectiveness of our army!"

Hanhai Emperor Yu Canghai was already drunk and decided, and when he sent Wang Du away, he immediately arranged for someone to start construction.

"Since this is the case, I immediately drew the drawings, and bothered the Canghai Emperor to arrange people to build according to the drawings I made. ”

Wang Du said that he would do it, and he immediately began to draw drawings, and the Hanhai Emperor Yu Canghai and Zhong Limo were watching from the side.

However, Hanhai Emperor Yu Canghai didn't just watch, he took advantage of this gap to call his subordinates and arrange for them to redeploy mining personnel and carve formations.

About an hour later, several drawings were handed over to the Hanhai Emperor Yu Canghai.

"These are the initial architectural drawings, as for the later stage of the need for something, I will arrange someone to build it personally, and when the time comes, I will ask the Emperor of Hanhai to help him more. ”

Wang Du had already thought about it, and when he returned to Xuantian City, he immediately transferred back to Gong Lian, and at the same time, he also asked Tang Shu to gather a large number of refiners and array mages again, as well as people who knew all kinds of strange arts.

The preliminary estimate is that there will be at least 1,000 people, and when everything is ready, Wang Du will teach them a unified lecture and teach them some knowledge of modern science and technology.

"Your Excellency, rest assured, this matter will be done. ”

As soon as Hanhai Emperor Yu Canghai arched his hand, he was already curious about what Wang Du was going to do!

"In that case, Emperor Hanhai, please send us back to Xuantian City. ”

Hanhai Emperor Jun Yu Canghai was a little bit enough, and then took Wang Du and Zhong Limo to the teleportation array, and under the personal send-off of Hanhai Emperor Yu Canghai, Wang Du and Zhong Limo stepped into the teleportation array.

When he came back to Xuantian City, he naturally appeared in Zhong Li's house and greeted Zhong Li Yuntian, Wang Du wanted to go back to Tang Shu to arrange manpower, but at this time he remembered that Tang Chu had gone to a far away star field.

"Yuntian Immortal Emperor, I don't know where the Yunkong Emperor is now, I have something I want to ask him for help. ”

Zhong Li Yunkong had already gone to heal his wounds, Zhong Litian didn't plan to alarm him out of the customs again, so he said:

"My eldest brother is in retreat again, and recently there are signs of another breakthrough in his cultivation. The second hall lord has the same to tell me. ”

Wang Du naturally didn't know that Zhongli Yunkong was actually suffering, and immediately he said:

"I need the Yuntian Immortal Emperor to mobilize a large number of refiners, alchemists and strange people who can use all kinds of strange doors and strange arts to come to Xuantian City, the number is about a thousand, I don't know if the Yuntian Immortal Emperor can do it?"

Zhongli Yuntian was really shocked when he heard that Wang Du wanted so many people, but with the energy of the Immortal Palace, this was not a difficult matter.
