after hearing the astronaut's words, Ye Su began to operate the drilling equipment and let the drill bit slowly come out of the hole.

Soon the drill bit returned to the ground, and Ye Su and they also appeared in front of a deep hole.

This big hole leads directly to the location of the alpha crystal and the ultimate destination of their operation.

Now they have penetrated hundreds of meters of ice, and the alpha crystals have been exposed to them.

What they're going to do now is go through this hole in the ice, descend to where the alpha crystals are, attach the alpha crystals to the ropes, and then they can go back.

Seeing the hope that the mission would be completed soon, all the astronauts began to get excited.

No one wants to stay in Neptune. It's good to go back early.

What's more, they can complete this difficult task with their eyes on it, and the victory is in front of them.

After seeing that the drilling work had been finished, Ye Su directly lost it to the controller in his hand, and stopped taking charge of the drilling control equipment.

Yesu is not interested in moving this heavy device back into the lander, so Yesu is going to dump it directly on Neptune this time.

It doesn't cost Yesu much to make this kind of equipment. Even if you lose Yesu directly, it won't hurt.

Anyway, this device has completed all its missions, and it's time to die.

After abandoning the drilling equipment, Yesu began to tie a rope to himself, preparing to reach the alpha crystal by cable descent.

"Get ready for the landing at once. Someone will come down with me."

"The remaining two men are waiting up there, ready to support us."

Because of the limited size of the hole in the ice, it can only accommodate two people to go down at the same time.

In addition, there must be someone watching the top, so Ye Su arranged for two astronauts to stay on the top, as long as one astronaut went down with him.

"I'll go down with Mr. Ye. My physical strength should be a little better and more suitable for this kind of work."

A young astronaut at this time took the initiative to stand out, ready to go down with Ye Su.

It seems that the young astronaut's courage is still very good, at least did not shrink in front of the dark hole.

This big hole, which goes straight under the ice layer hundreds of meters deep, is frightening enough to see at the bottom.

Ordinary people really dare not ask to drop into this, especially in the Neptune environment, the danger is too big.

As long as a little careless, maybe it will stay in this hole forever.

At that time, the corpse capital will not be able to return to earth. It will have to stay on the icy planet Neptune, which will be frozen by thick ice.

It's a terrible end just to think about it. It's good that he can stand up at this time.

Since the young man asked to go down with Ye Su, Ye Su readily agreed to his request.

"Well, you can come down with me."

"The remaining two people will stay on the ground and observe the surrounding situation at any time. If there is any accident, we will be informed immediately."

Ye Su explained with the fastest speed, and began to prepare for the matter of landing.

Two minutes later, Yesu and the astronaut firmly fixed a rope on his body.

"One, two, three, go!"

When she was ready, Ye Su counted down three times and jumped into the dark hole.

Ye Su is in the middle of the ice, and tries to control his falling speed with the rope falling device.

The rope lifter and the rope began to rub violently, and the friction generated by the friction began to counteract Yesu's own gravity, so that the speed of Yesu's fall became smooth.

Yeosu is just a little bit down toward the bottom, slowly approaching the location of the alpha crystal.

The young astronaut in the back also followed yessou down.

Their bodies slowly disappeared into the cave, into the deep darkness.

Due to the depth of the ice layer is too deep, and there is not enough sunshine here, so the hole looks extremely dark, and it is almost impossible to reach for five fingers.

Ye Su and they would not have known where they had landed if they hadn't had lighting on their spacesuits.

With the help of the spacesuit lighting equipment, Yesu can see the surrounding situation clearly.

Neptune's ice layer has very few impurities and looks very crystal clear.

All around are thick ice, and now Yesu and they are in the middle.

Now ye Su looked up and couldn't see the hole on the top. Looking down, she couldn't see the bottom.It is the most frightening place to be in such a place.

The dark and narrow environment around will stimulate the most fear in people's heart.

This kind of environment is very depressing. People with poor psychological quality will go crazy if they stay for a while.

Fortunately, Ye Su and the young astronaut are all people with high psychological quality.

They ignore the environment they are in and concentrate on descending towards the bottom.

After a period of dark journey, Yesu finally saw the alpha crystal under her feet.

The volume of alpha crystals is not very large, only less than one meter long.

A small piece of material weighs several tons, which shows that the density of this special material is very high.

When Yesu saw the appearance of alpha crystal, he confirmed that this was what he had been looking for.

In the light of the light, the whole alpha crystal shows a very special appearance.

The alpha crystals look like they're unreal, and the whole crystal appears and disappears from time to time, and it feels very unreal.

This state between the unreal and the real is the biggest feature of alpha crystal.

This special material itself has two states: the unreal state and the real state. These two contradictory states appear on this crystal at the same time.

It is this nature between fantasy and reality that makes him the best engine material.

It takes just a little bit of alpha crystal to generate a lot of power from the engine.
