This is a huge underground space. In some areas without roots, there are some instruments, some of which have been rotten, and some of which remain roughly the same.

When he was in the sink, Ning Tao imagined an underground city. Maybe he would meet survivors. In that case, the problem would be much simpler. But no, in the area where the fire can shine and the eye can see, this place is more like an underground base for scientific research.

But I only see a small part. Maybe there are other possibilities.

"Let's go and have a look." Ning Tao walked down the platform with a torch and walked along a road.

Bi Mingzhu followed Ning Tao, looking left and right for all useful things.

As the 0 of the 10 combination, Ning Tao is responsible for major events, such as tools, food and clothes. That's what she is responsible for.

At least she is also the leader of the three worlds. She is not a vase. She will install the vase only when Ning Tao wants to see it.

"Old send, you wait." Not far away, Bi Mingzhu shouted to Ning Tao. Without waiting for Ning Tao to reply, she walked to a corner.

Ning Tao said curiously, "what are you doing?"

Bi Mingzhu said, "I'll go there and have a look. There may be something useful there."

As she spoke, she had come to the corner, where there was an alloy cabinet and some very rotten instruments. She reached out and tried to open the cabinet, but she couldn't open it. She drew a metal stick from the rotten instrument, then inserted it into the door of the cabinet and pried it hard. The door of the cabinet clanged open.

Ning Tao walked past with a torch in his hand.

Bi Mingzhu pulled out several things from the cabinet, a sharp looking alloy axe, a helmet with lighting device, and some things with unknown names. But most of them are rotten. She broke them with her hands, and some even turned into dust.

Only from these situations, we don't know how many years this underground base has existed and what it is used to study.

Bi Mingzhu handed the alloy axe to Ning Tao: "you can use this axe, which is much stronger than your metal fragment."

Ning Tao took the alloy axe in his hand and waved it. He took advantage of everything.

Bi Mingzhu began to fiddle with the helmet again.

The material of that helmet is neither plastic nor metal. It looks like a very special material and is very light. This helmet can withstand the weathering of years. It must be a very advanced material.

"What do you want that hat for?" Ning Tao asked.

Bi Mingzhu said, "there is a lighting device on this hat. I'll see if I can turn on the light. Your torch won't last long."

Ning Tao said, "this base has been abandoned for hundreds of thousands of years. I'm afraid the battery in it can't be used for a long time. How can you turn on the light on your hat?"

As soon as his voice fell, a bright beam of light suddenly released from the hat in Bi Mingzhu's hand. The beam of light shone on his face impartially. He subconsciously raised his hand to block the beam and the embarrassed look on his face.

Bi Mingzhu put her hat on her head and couldn't wait to move the speed of light farther.

Ning Tao said curiously, "Pearl, how did you get it? What's the battery in the hat, so awesome?"

Bi Mingzhu said with a smile, "the lighting device in this hat doesn't use a battery, but physiological electricity. When I activate it, the electrical ions in my body can be transmitted to the hat for illumination

The bright device can also light up. "

"Physiological electricity... So bright?" Ning Tao can't believe it.

Bi Mingzhu said: "this technology is not an advanced technology in the cosmic world dominated by us. In my hometown, even children can play with it. Don't you pay attention to these in the cosmic world dominated by you? What are you usually busy with?"

Ning Tao: "

There must be such technology in the cosmic world he controls, but he is busy sending children, taking children and grandchildren. He doesn't have time to pay attention to these. However, unlike the other three realms, most of them have lived for hundreds of millions of years, and the science and technology in their respective cosmic world must be very familiar.

In a word, the God of giving birth has never been a serious Lord of the three realms.

With the lighting device, the torch is useless. Ning Tao threw the torch on the ground and subconsciously raised his feet to step on it. Only then did he find that there were no shoes on his feet, and then retracted his feet back.

But it was this lift, look and shrink. Ning Tao found something hidden in the dust next to the torch. He then squatted down and scraped away the dust and debris with his hands.

A tree root was revealed from the dust. It was as thick and thin as an arm and had been dried to death.

Ning Tao reached out and touched the dry roots. A familiar feeling came from his fingertips. At that moment, a wonderful feeling came into his heart. He was a little stunned, and then said, "Pearl, look at the root... Is it the root of the apple tree that gave us a new life?"

Bi Mingzhu squatted beside Ning Tao, lowered her head and illuminated the tree roots exposed from the dust with the lighting device on her hat. She also reached out and touched, and a surprised and confused expression appeared on her face: "Lao song... Did you just say that this root is the root of the apple tree that gave us a new life?"

Ning Tao nodded.

"How is this possible?"

Ning Tao said, "under that apple tree, I specially saw those roots. This root is the same as those roots. And when I touched it just now, I had a strange feeling in my heart."

Bi Mingzhu blurted out, "it's like a mother's hand."

Ning Tao was stunned for a moment. In fact, he had not thought about how to describe the strange feeling that was fleeting just now, but unexpectedly, Bi Mingzhu said it at once. Although this statement is very strange, he thinks it's true.

However, even if his mother, Ning Tao is not willing to admit that an apple tree is his mother.

Bi Mingzhu then added, "bah, bah, bah, what am I talking about? How can an apple tree be our mother? If that tree is our mother, aren't we brothers and sisters? I don't want to be your sister or sister. You're my man."

Not really.

Are Adam and Eve brothers and sisters?

No one said Adam and Eve were brothers and sisters.

Naturally, the God of giving birth and the goddess of beauty are not brothers and sisters, although they both bear fruit from a ◇ zero tree.

"Just have a light. Let's walk along the root of the tree to see where it extends." Ning Tao changed the subject.

Bi Mingzhu nodded her head. She stood up and walked forward with her feet on the roots in the dust. Ning Tao used to lead the way with a torch. Now she leads the way with a helmet.

Ning Tao noticed that the helmet on the head of Bi Mingzhu was green, and several Chinese characters and numbers were written on the back.

250 Tiandao base.

Green hat, No. 250, which is the color and number Ning Tao doesn't like, but it's not the point. The point is "Tiandao base".

Tiandao base?

From the discovery of the alloy shrapnel to the discovery of the base, the discovery of alloy pipes and water tanks, and the sight of those rotten and barely intact machines and instruments, Ning Tao always felt that this was a human scientific research base. Although it was abandoned and no one was seen, it was roughly certain.

But when he saw the sign of "Tiandao base", he was not sure.

In this little time, Ning Tao has some associations in his mind: "Pearl and I are both masters of the three realms, and then become seeds. The universe we dominate is a virtual world. In that seed space, I have some special abilities, and my blood is also golden divine blood. But here, I have no magic power, and even the blood is the blood of ordinary people... Is all this..."

What is all this?

But he couldn't say it, and he didn't even have a sense of direction in his heart.

It's just a feeling. It's vague, ethereal and mysterious.

Bi Mingzhu suddenly stopped. Ning Tao was careless and hit her back.

Fortunately, the axe was in his hand, but he was poked by a firewood stick.

"What did you find?" Ning Tao came around the Bi Mingzhu.

Bi Mingzhu raised her finger to the front and said, "look there."

The beam of light from the green hat above her head also shone in that direction.

Ning Tao passed his eyes.

There stands a hemispherical building about 100 to 200 meters in that direction. The roots of the trees at the foot also extend to the hemispherical building. After a distance, they can't be seen. I don't know whether they have dived underground or extended into the hemispherical building.

"Let's go and see if we can find anything." Ning Tao said.

"Yes." Bi Mingzhu answered, then remembered something and said, "old send, what did you stab me with just now?"

Ning Tao was embarrassed and said, "I saw the words on your hat and had some thoughts in my heart. I bumped you carelessly. It was a firewood stick that stabbed you."

Bi Mingzhu suddenly realized: "Oh... I mean so hard."

"Don't you see the words on your hat?" Ning Tao tried to divert her attention.

Bi Mingzhu said curiously, "is there a word on my hat?"

"250 Tiandao base." Ning Tao said.

Bi Mingzhu then took down her hat, looked at it and said curiously, "it's really strange. Why didn't I see it just now?"

Ning Tao said, "the hat was covered with a layer of dust just now. When you walk, the dust falls off and the words below are revealed. But it's not important. What's important is the Tiandao base. What do you think it is?"

Bi Mingzhu thought for a moment, then shook his head: "I understand the way of heaven and the meaning of the base, but when the two are added together, I don't know what it means."

Ning Tao was not surprised by the result. He said, "forget it. Don't think about it for the time being. Let's go to the building."

"Well, if only there was water there. I'm itchy. I want to take a bath." Bi Mingzhu said.

They talked and walked towards the hemispherical building.

What's in that building?

I don't know.
