The white haze is diffuse, and a simplified type of science fiction with a multi-function robotic arm appears. The Lord's chariot of the high-frequency cutting knife is at the bottom of the cave.

All the searchlights on the Lord's Chariot are turned on, illuminating the entire cave.

Ye Qing recruited a Master Craftsman and unfolded a triangular-shaped model drawing on the light of the Lord's chariot.

"I plan to build three floors of the whole industrial base." Ye Qing's Master Craftsman beckoned: "come here and have a look. What kind of support is the best support for the whole building?”

In fact, when the alloy material is used as a whole and concrete is poured, the industrial base will not collapse without any support.

But whether it is in architecture or the industrial sector.

The word "qualified" has never been the pursuit of the industry.

For example, a bullet-proof insert board can resist at close-range shooting that is qualified. But who can guarantee that the bullet hit it must be 7:62 mm caliber?

In case of being hit by a sniper rifle or an anti-equipment rifle?

By the same token, a building is only stable. So, in case of an earthquake or an attack, wouldn't you be blind?

Greed is the biggest driving force for technological progress and the source of the best products.

Therefore, Ye Qing naturally wants to make the industrial base a secret fortress for the impregnable.

The third floor; the first layer is used for the production and research and development of large-scale industrial products, the second layer is used for laboratory-like functions, and the third layer is the refuge floor with complete life security settings, which can independently let Ye Qing live for more than half a year.

The three caves of Rex Rabbit, it is reasonable to say there is a refuge layer, it is best to have a secret escape route.

However, the cost of building that thing is too high. He really wants to be trapped in the ground. Ye Qing calls out angry miners to dig slowly.

The Master Craftsman added eight load-bearing walls to the base, and the bottom refuge layer, according to the most reasonable space, planned equipment placement.

Whether the structure is designed or not, the bottom of the cave should be expanded again.

The central main pillar that takes into account the function of the elevator.

Go all the way to the bottom rock layer. According to the early geological data provided by the Bureau of Land and Resources, the rock formation is 110 meters to 130 meters below the city center.

The lord's chariot was started by Ye Qing, preparing the angry miners to dig together.

Ye Qing is ready to dig into the rock layer, and then the industrial base will regard it as a bearing layer.

This time, Ye Qing personally sat in the lord's chariot.

If the shape is not too weird, the Lord Chariot is definitely one of the most suitable means of transportation for private use.

Waterway amphibious, with independent support equipment, rich retrofit features, and incredible cabin protection glass. Sitting here, even if you accidentally collapsed the cave, Ye Qing can slowly drill to the surface by the Lord's chariot.

The high-frequency cutting blade is activated, and the cutting blade has an amplitude of thousands of times per second. The cutting soil is exactly equal to the cutting air.

Over there, the angry miner turned into a pangolin and the forelimbs madly smashed the dirt, and soon the whole body was drilled into the soil.

The overhead crane is also carrying the soil at a time, with a capacity of 20 tons and a round trip in five minutes.

Focus on work, time is always fast.

When the crane had been carrying thousands of tons of soil, Ye Qing drove the lord chariot and repeated many times the cutting operations.

The high-frequency cutting knife inserted into the soil suddenly came with a different sense of stickiness.

There is something in the soil below!

Ye Qing suddenly came to the spirit and quickly cleaned up the dirt in front.

A dark brown barren stone wall appeared in front of Ye Qing's eyes. The stone wall was uneven, and the mouth was just cut by the cutting knife. At this time, there was a slight water stain.

This knife seems to be cut on a living rock, and the clear water is its blood.

Stopping the high-frequency cutting knife, Ye Qing opened the door of the Lord's chariot and smashed a scorpion outside the slope.

"I came to the boss." The Master Craftsman hurriedly ran into the bottom of the slope and saw the rock at first glance and said: "Boss, this should be the rock layer of the underground."

“How many meters are there from the grounds?”

"133 meters."

"That's right, the rock layer marked on the geological data of the Bureau of Land and Resources is also this depth."

Ye Qing claps his hands. If he thought well: "The rock layer is the most stable bearing layer of all foundations. They have incompressibility, and the foundation is hit here without worrying about the uneven fall of the building."

“If the depth of the rock is set in a certain depth, the building's ability to resist overturning and slipping will be greatly improved.”

"Shh ~"

All of a sudden, the Master Craftsman made a squeaking action. Then he took some steps to make Ye Qing's heart hair and gently came to the rock layer at the end.

The master of the master is kneeling on the ground, his ears clinging to the rock layer, and he seems to be listening.

"I... I don't scare me by you!"

Standing 133 meters underground, if you are alone even if the special forces are coming. You will collapse in the dark and dead environment. The master of delicacy has put on a posture of movement and stillness in the stone.

Ye Qing’s heart must be pulled out.

"Boss, there is a movement behind the rock." The fine master grinned and said Ye Qing could come and listen.

"What...something?" Ye Qing has jumped into the lord's chariot.

"The sound of water, the sound of flowing water."

"You scared me, dog." Ye Qing constantly smoothed the beating heart, jumped out of the car again, and motioned to Master Craftsman not to speak.

Stopping communication, it seems that the whole world is silent, and Ye Qing listens calmly and listens.

"Dong Dong ~ Dong Dong ~ Dong Dong ~"

The first sound printed into the eardrum is the strong beating of the heart, followed by an imperceptible but real noise of water flow.

Ye Qing also learned from the Master Craftsman, lying on the rock.

The more vivid sound of the water is singing as if under the rock, there is a dark river hidden by unknown people.

"No!" Ye Qing holds his head, how can there be a dark river in the underground?

The Master Craftsman of this problem can't answer. He is invincible in the field of industrial processing, and his knowledge of geography is even whiter than Ye Qing.

Although Ye Qing went to university, he did not major in geography. He also knew that underground rivers usually existed only in mountainous areas. In the plain area, because of the small difference in terrain. It is unable to meet the requirements of underground dark river flow. So, it is difficult to form a dark river.

It may not be the underground dark river. Ye Qing remembers going to school. Geography teachers once said that during the evolution of the earth in the billions of years, there have been many cracks, gaps, and reservoirs in the rock layer.

A large amount of groundwater in the space of these rocks is a very pure natural source of water, as long as it is not present in minerals or coal seams.
