Compared with the ghost in the 'Five Ghosts Soul Refining Banner', the bronze corpse is more like a perpetual motion machine. It has greater power and moves faster.

The bronze corpse's shortcomings are also obvious. It has no ability to cast spells or perform long-range attacks like flying swords. It is a typical melee fighter.

Li Shiming took out the giant axe from the storage bag and handed it to the bronze corpse.

The bronze corpse was very obedient under normal circumstances and took the giant axe.

Li Shiming brought the bronze corpse to a corner of the training room. He first took out the Fiery Sword and mobilized his spiritual power to cut the wall.

He dug very carefully and soon found a cubic rock on the wall, which he put into his storage bag intact.

He called the bronze corpse and instructed it to dig downwards.

Using the bronze corpse to build an underground space can not only reduce one's own troubles, but also exercise control over the bronze corpse.

There are two ways to control the bronze corpse. One is that Li Shiming issues a clear order to the bronze corpse through a blood contract, and the bronze corpse will obey this order.

If Li Shiming gave the bronze corpse an order to attack a certain target, the bronze corpse would rely on its own fighting instincts and attack that target with all its might until the target was dead.

Second, Li Shiming directly controlled the bronze corpse through the blood contract, and at this time the bronze corpse was like a puppet and obeyed his control 100%.

Of course, he couldn't let the bronze corpse do anything beyond its own capabilities. For example, if he wanted the bronze corpse to mobilize its spiritual power to release a "Spring Breeze and Rain Technique", at least the bronze corpse couldn't do it at the moment.

A downward passage was being dug quickly inside the small hill, and all the rocks and soil were collected by Li Shiming into the storage bag.

He did not dig randomly. After careful observation, he made a topographic map of Eagle Island in IBM z15, and formulated an excavation plan by analyzing the conditions of the stone walls in the cave.

With the operation of the bronze corpse, the excavation work became very simple.

With his enormous strength and a low-grade giant axe magic weapon, he could dig up a large area of ​​rocks or soil at once.

After digging down for ten meters, Li Shiming ordered the bronze corpse to open up underground space.

It was ten meters high, and with his physique, he didn't need a ladder and could get in and out easily.

At the upper hole, the cubic rock has been finely processed at the micron level in the computer room so that it can fit perfectly with the gap in the wall.

He had no intention of using any monastic methods to find the entrance to the underground space. With his strength, it would be safer to just block it with rocks than to use any monastic methods.

He plans to build an underground space of 100 square meters, and three meters high.

According to IBMz15's calculations, such a large underground space should theoretically be within the mountain rock and have sufficient support.

Li Shiming's ten cubic storage bags were not enough. He repeated this several times and went out of Yingzui Island to dump out the rocks and soil he had dug out.

There was sea all around, and the soil and rocks poured into the sea without leaving any trace.

Just when the bronze corpse had finished digging the basement and was only one corner short, the giant axe suddenly cut through the rock.

Li Shiming, who was controlling the bronze corpse, sensed something was wrong through the blood contract, and the giant axe immediately stopped moving.

He came to the rock, took out the Fiery Sword and carefully cut the rock. A hole appeared in the last corner of the basement.

The entrance of the cave appears to be naturally formed, with no traces of artificial carving.

He was a little depressed. He was digging the basement but ended up digging through it and had no idea where the base led to.

He took out the drone and put on a blindfold. His monk's methods were limited, so he could only use technology to explore.

We can't let the bronze corpse go down. The bronze corpse is very powerful, but who knows how deep it is down there and whether we can get out if we fall down.

Drones are great and can fly, and as long as they stay within the range of the remote control, there is no problem.

Even if it is out of the remote control range, the drone's built-in automatic return system will return to him along the original route as soon as possible.

The drone started up and flew down along the somewhat winding entrance of the cave. The drone flexibly dodged left and right. After going down for more than thirty meters, it moved forward for more than a hundred meters to the right, and then went down for about five meters. The picture Li Shiming saw in his goggles suddenly became larger.

The drone turned on its night vision function and found that in the underground without any light, there was a huge space beyond imagination.

The 100-square-meter basement that Li Shiming planned to dig was already quite large, considering that Yingzui Island was not that big.

But who would have thought that there was a huge space under Eagle's Beak Island.

No, this is not underground Eagle Island, but on the seabed. That location and depth have already left Eagle Island and gone deep beneath the sea surface.

Li Shiming became interested in this underground space. He wanted to build a science and technology base, but one hundred square meters seemed a bit small.

He controlled the bronze corpse and dug and expanded the hole that naturally opened downwards to a size large enough for him and the bronze corpse to enter.

After a short time, a new passage was repaired, and a platform for people to rest was dug out at the underground exit. Li Shiming stood on the platform.

The underground space was very dark, so he took out a lamp, which was a battery-powered technological product, a completely sealed lighting lamp designed for convenient underwater use.

This was also a product of boredom during his training. He had experienced underwater battles and considered various possibilities, which gave him a lot of ideas.

He threw the sealed lighting lamp into the underground space, and the underground space was immediately illuminated.

With his eyesight, he can see a lot of things clearly as long as there is a little light.

The underground space is about the same size as an indoor professional basketball court. Except for a pool of water with an area of ​​about 30 square meters in the underground space, the rest of the ground is very dry.

"That's not right. How can it stay dry here under the sea?" Li Shiming calculated the exact location of the underground space through IBM z15, and he muttered to himself in confusion.

If this underground space is sealed, how does the air stay fresh?

You must know that when a space is in a closed state, the air will inevitably be polluted.

He took another breath of air, but immediately his expression became strange.

After taking a breath of air, he felt that the concentration of spiritual energy in the air was very unreasonable.

This is definitely not the spiritual energy concentration of a second-grade spiritual vein. It is probably about the same as the concentration after the spiritual energy is gathered in the spirit gathering plate.

It is impossible for a second-grade spiritual vein to have such a concentration of spiritual energy, unless there is another spiritual vein here!

The more Li Shiming thought about it, the more likely it seemed. This also explained why the air in this enclosed space was so fresh. The spiritual vein had the function of purifying the environment.

He jumped into the underground space. The ground was very hard. He then observed other places in the underground space.

It can be judged that the entire underground space is the interior of a whole rock, and no cracks are found. No wonder seawater cannot come in.
