Chapter 1690

The problem of water has been solved, and now there is only one problem of food. If you eat cactus leaves and medlar every day, it's not the case after all. Moreover, cactus and medlar grow in the canyon. It's difficult to climb up from the metal pipe. It's not a way to travel long distances in order to eat.

But the hope of finding food in this underground base seems very slim.

When the group walked about four or five kilometers, a brown rock wall appeared at the end of the two beams. Water also drips down on the rock wall, so that some of the rock walls appear very wet and moss grows out.

Bi Mingzhu said excitedly, "I said there must be an edge in this underground base. This is the edge. There is still water here. I'll decorate the water."

Ning Tao came to the rock wall. Bi Mingzhu filled the water in the small puddle under the rock wall. He collected the moss on the rock wall.

Moss is rich in green and carotene. It also has certain anti-inflammatory function. It can be eaten as a snack in an environment without food.

He washed a small piece of moss and chewed it in his mouth. It tastes a little astringent, but it's not bad.

Bi Mingzhu said curiously, "can you eat this little plant?"

Ning Tao said, "it's called moss. You can eat it. Have a change."

Then he handed Bi Mingzhu a small piece of moss. Bi Mingzhu put it into his mouth and chewed it. Then he smiled and said, "it tastes good. It seems that we have found another granary."

Ning Tao smiled: "it's not good to eat this for a long time. Let's continue to explore, and maybe we will have a better discovery."

"Shall we go back the same way or follow the rock wall?" Bi Mingzhu can't make up her mind.

Ning Tao thought for a moment: "let's go back to the middle line obliquely. I'm afraid the people who built this base won't make an issue in the edge area. Important facilities should be in the middle area. If we want to find something, we have to go to the middle area."

"Well, listen to you." Bi Mingzhu said.

Found water and food, although only moss, but it also gave her great hope, so she is very happy now.

Ning Tao led Bi Mingzhu to the center of the underground base obliquely and continued to explore all the way. Along the way, he knocked open several metal cabinets and found more green hats, but he already had a green hat on his head, and he couldn't wear it if he wanted it again.

Returning to the center again, not far away, a tree root emerged from the ground and extended in the direction of the apple tree.

The waves are thicker than the ground, and the roots are bigger than the ground. It stretches straight ahead, twists and turns, and can't see the end at a glance.

Ning Tao came to the root of the tree, put down the blue bone hammer in his hand and reached out to touch the root of the tree. I don't know why, at the moment when his finger touched the root of the tree, a strange feeling surged up in his heart. It was like touching himself!

"Lao song, this tree root is dead. Half of the apple tree that gave us new life is fresh, but until now, we haven't found any fresh roots. Don't you think it's strange?" Bi Mingzhu said.

Ning Tao said, "if we go further, I'm sure we can find fresh roots."

As soon as the voice fell, a blue light suddenly flashed through the tree roots. At that moment, the tree roots in front of me seemed to turn into blue crystal.

The blue light is so strong that Ning Tao and Bi Mingzhu have two green on their heads

The lighting of the hat was eclipsed. But it lasted so short that it disappeared in less than a second.

"Just... The blue light..." Bi Mingzhu wanted to say something, but she didn't say it. The scene was really shocking.

Ning Tao was also stunned. He didn't come back until more than ten seconds later. He said, "it must be that machine. It has woven a virtual universe world and sent it to the apple tree."

"We activated the machine. Is that what the apple tree gives us new life?" Bi Mingzhu was confused.

Ning Tao said, "the person who created the machine should have thought of having seeds like you and me, but we don't know what his purpose is. Let's go on, let's go to the foot of the apple tree."

When they found the root of the tree, they would never get lost at the foot of the apple tree, but they were confused and couldn't guess what was going on there.

Ning Tao and Bi Mingzhu walked along the tree roots. They didn't go far. Just a few minutes later, another blue light flew through the tree roots. The darkness ahead was dispersed by the blue light, showing a large number of machines and instruments, a rotten and messy scene.

Just walk and walk. When you are tired, take a rest, drink water and sit on the root of the tree. If you find something worth studying, stop and have a look and think about it.

Anyway, Ning Tao and Bi Mingzhu are the only people in the world until now. He has plenty of time and is not in a hurry.

In this way, about ten hours later, Ning Tao and Bi Mingzhu returned from the underground base to the foot of the apple tree.

When the bright light beam reached, it was a large area of large and small tree roots that fell down from the kilometer high rock layer, like a large net, covering a large space layer by layer.

The roots of those trees are half alive and half dead, which can be distinguished from the color at a glance.

At the first sight of so many roots, Ning Tao and Bi Mingzhu were shocked. The apple tree was only a hundred meters high, but I didn't expect that its roots were so developed that they penetrated the soil and rock walls, and could fall for kilometers and take root underground.

But it seems that there is no need to be surprised. An apple tree containing hundreds of millions of virtual universe world and ending two new fruits is an extremely magical and mysterious existence in itself.

"There..." Bi Mingzhu suddenly pointed to a place among the roots of the tree and said excitedly, "old send, look there!"

Ning Tao looked in the direction she pointed, looked through the layers of large and small tree roots, and then saw a building hidden in the tree roots.

The building is also a hemispherical shape. There is a huge stone tablet in front of it, which makes him feel like a tomb at first sight.

grave?

How can there be a grave in such an underground base?

Ning Tao was so curious that he couldn't help walking to that place.

Bi Mingzhu followed closely: "old send, be careful, I think that place is a little strange."

"Do you think it looks like a grave?" Ning Tao said as he walked.

"Grave?" Bi Mingzhu shook her head. "I think it's like a temple."

Ning Tao's lips moved, but he still gave up the discussion. He and Bi Mingzhu are the three worlds from different cosmic worlds

Lord, there are different races and cultures. Perhaps in the cosmic world dominated by Bi Mingzhu, the appearance of those large and small temples is not necessarily the appearance of tombs.

There is no point in discussing these at this time.

They soon came to the tree root net. When they were ready to drill in, another blue light passed from the thick dead tree root. At that moment, all the roots were lit up and turned into blue crystal roots one after another. The scene was full of mystery and incomparable grandeur.

But the spectacle lasted only a second and then disappeared. On the root of the tree, there was no trace in the surrounding space. It is so bright, but it has not changed anything.

"Old send, where do you think the blue light went?" Asked Bi Mingzhu.

Ning Tao thought for a moment and then said, "did you and I all think that the virtual universe compiled by that machine was sent to the apple tree through the tree root?"

Bi Mingzhu nodded her head: "isn't it?"

Ning Tao pointed to the building that was the tomb and said, "I suddenly felt that the virtual universe woven by the machine was sent into the building, but I'm not sure. Let's go in and have a look."

Bi Mingzhu answered, and then followed Ning Tao into the tree root net.

The building hidden in the roots of the tree was getting closer and closer. Ning Tao found that it was bigger than what he saw outside. The stone tablet is at least a hundred meters high, and the hemispherical main body behind it is two or three hundred meters high, much larger than a football stadium.

They said they were going in, but they frowned at the hemispherical building.

The hemispherical building doesn't even have a door, neither does the hemispherical main body, nor does it stand on the stone tablet in front.

"No way. How can I get in?" Bi Mingzhu looks very depressed.

Ning Tao thought for a moment and said, "maybe we can try the previous method. It may be useful."

With that, he put his hand on the stone tablet.

The stone tablet did not move, but as soon as he opened his palm, a blue light suddenly lit up from the place where his palm touched, and then extended in all directions.

In a moment, the 100 meter high stone tablet was lit up. The ordinary stone tablet, which was still brown, turned into a huge blue crystal tablet in a twinkling of an eye. It was crystal clear and exuded a faint blue light.

Ning Tao was stunned by the fantastic scene in front of him and could not move in front of the stone tablet.

"This..." Bi Mingzhu was also stunned. She also ran to the side of the hemispherical building, stretched out her hands against the stone wall, and raised her hands after a slight pause.

However, Ning Tao just touched the stone tablet and lit up the whole stone tablet. She touched it with her hands. After she raised her hands, there was no response on the hemispherical building.

"Why can't I?" Bi Mingzhu was a little unconvinced and simply patted twice with her hand.

Still no response.

Ning Tao came over and didn't speak. He raised his hand against the stone wall of the hemispherical building. After staying for two seconds, he lifted it up.

A blue light suddenly appeared from the stone wall and then extended in all directions. In a twinkling of an eye, the whole hemispherical building was also lit up, emitting a faint blue light and crystal clear.
