The problem of water is solved, and now there is only one problem left for food. If you eat cactus leaves and goji berries every day, it will not be a problem after all, and both cacti and goji berries grow in canyons, and it will be difficult to climb up from the metal pipes, and it is not an option to walk long distances to eat something.

But if you want to find food in this underground base, the hope is slim.

10 When the group had walked about four or five kilometers, a brown rock wall appeared at the end of the two beams. There are also water droplets dripping down the rock face, so that some of the rock wall appears very wet, and moss grows.

Bi Mingzhu said excitedly: "I said that this underground base must have a side, this is the edge, there is still water here, I will decorate some water." ”

Ning Tao came to the bottom of the rock wall, where Bi Mingzhu filled the small puddle under the rock wall with water, and he collected the moss on the rock wall.

Moss is rich in green pigment and carotene, and also has certain anti-inflammatory properties, so it can be eaten as a snack in an environment where there is no food.

He washed a small piece of moss and put it in his mouth to chew, it tasted a little astringent, but it wasn't unpleasant.

Bi Mingzhu said curiously: "Can this little plant be eaten?"

Ning Tao said: "It's called moss, you can eat it, you can eat it too, change the taste." ”

Then he handed Bi Mingzhu a small piece of moss, and Bi Mingzhu also put it in his mouth and chewed it, and then said with a smile: "It tastes good, it seems that we have found another granary." ”

Ning Tao smiled: "It's not okay to eat this for a long time, let's continue to explore, maybe there will be better discoveries." ”

"Shall we go back the way we came, or should we go along this rock wall?"

Ning Tao thought for a moment: "Let's return to the middle of the route diagonally, the people who built this base, I'm afraid they won't make a fuss in the edge area, important facilities should be in the middle zone, if we want to find something, we have to go to the middle ground." ”

"Well, listen to you. Bi Mingzhu said.

The discovery of water and food, although it was only moss, also gave her a lot of hope, so she is happy now.

Ning Tao led the blue pearl diagonally to the center of the underground base and continued to explore. Along the way, he knocked open several metal cabinets and found more cuckolds, but he already had a cuckold on his head, and he couldn't wear any more cuckolds.

Not far back into the center, a tree root emerged from the ground and stretched in the direction of the apple tree.

The roots of the trees that emerged from the ground were very thick, thicker than Ning Tao's waist. It stretches and twists and turns, with no end in sight.

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 before his death. I don't know why, but the moment my fingers touched the roots of the tree, a strange feeling welled up in his heart, and that feeling ...... It's like touching himself!

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

Ning Tao said: "If we go further, I believe that we will definitely find the fresh roots." ”

As soon as he finished speaking, a blue light suddenly flashed from the roots of the tree, and at that moment, the roots in front of him seemed to turn into blue crystal crystals.

The blue light was so intense that the two green ones on the heads of Ning Tao and Bi Mingzhu

The lighting fixtures of the hats are overshadowed. However, it lasted very short, disappearing in less than a second.

"Just ...... The blue light ...... "Bi Mingzhu wanted to say something, but the words came to her mouth and she didn't say it, the scene was too shocking."

Ning Tao was still stunned, and only came back to his senses after more than ten seconds, he said: "It must be that machine, it weaves a virtual universe world again, and then sends it to that apple tree." ”

"We activated the machine, is this what that apple tree gives us a new lease of life?"

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

Having found the roots of the tree, they would not get lost at all if they walked to the foot of the apple tree, but what was going on there, the two of them were confused in their hearts, and they couldn't guess at all.

Ning Tao and Bi Mingzhu walked forward along the roots of the tree, and they didn't go far, and only a few minutes later, another cloud of blue light flew through the roots. The darkness ahead was dispelled by blue light, revealing a large number of machines and instruments, a scene of decay and disarray.

Just walk and walk, and when you are tired, you will rest and drink saliva, and sit on the roots of the tree. If you find something worth researching, stop and look at it and think about it.

Anyway, this world has only given Ning Tao the feeling that there are only two people, him and Bi Mingzhu, he has time, and he is not in a hurry at all.

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

As far as the snow beam came, a large number of large and small tree roots fell from the kilometer-high rock formation, like a large net, covering a large space in layers.

The roots are half alive and half dead, which is instantly distinguishable from the color.

When they saw so many tree roots for the first time, Ning Tao and Bi Mingzhu were shocked. The apple tree was only about 100 meters high, but he didn't expect that his roots were so developed, penetrating the soil and rock walls, and even falling for thousands of meters, and then taking root in the ground.

But there seems to be no surprise that an apple tree containing hundreds of millions of virtual universe worlds, and an apple tree that has ended two new fruits, is itself an incomparably magical and mysterious existence.

"...... 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, his gaze passed through the layers of large and small tree roots, and then saw a building hidden among the roots.

The building was also in the shape of a hemispherical shape, with a huge stone monument in front of it, which at first glance gave him the impression that it was a tomb.

Grave?

How could such an underground base have the existence of graves?

Ning Tao was curious in his heart, and he couldn't help but walk towards that place.

Bi Mingzhu followed closely: "Old send, be careful, I think that place is a little weird." ”

"Don't you think it looks like a tomb?" Ning Tao said as he walked.

"Grave?" Billy Pearl shook her head, "I think it's like a temple." ”

Ning Tao's lips moved, but he still gave up the discussion. He and Emerald Pearl are from the Three Realms of different cosmic worlds

Lord, different races and cultures are different, maybe in the universe dominated by the blue pearl, those large and small temples are not necessarily tombs.

There is no point in discussing these at this time.

The two of them soon came to the root net, and just as they were about to get inside, another blue light passed through the thick, dead root. In that instant, all the roots of the tree were lit up and turned into blue crystal roots one after another, and the scene was full of mystery and incomparably magnificent.

However, the spectacle only lasted for a second, and then vanished. There is not a trace left on the roots of the tree, nor in the surrounding space. It's so bright, but it doesn't change anything.

"Old send, where do you think that blue light went?" asked Bi Mingzhu.

Ning Tao thought for a moment before he said, "Do you and I think that the virtual universe world compiled by that machine was sent to the apple tree through the roots?"

Bi Mingzhu nodded: "Isn't it?"

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

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

The building hidden in the roots of the tree got closer and closer, and Ning Tao realized that it was even bigger than what he saw outside. The stele is at least 100 meters high, and the hemispherical body behind it is also two or three hundred meters high, much larger than a football stadium.

said that they were going in, but when they arrived at the hemispherical building, the two of them frowned in unison.

This hemispherical building does not even have a door, nor does it have a hemispherical body, nor does it have a stone monument standing in front of it.

"How can I get in if I don't have a door?" Bi Mingzhu looked very depressed.

Ning Tao thought for a moment and said, "Maybe we can try the previous method, maybe it will be useful." ”

With that, he reached out against the stele.

The stele remained motionless, but as soon as he opened his palm, a blue light suddenly lit up from where his palm had touched, and then expanded in all directions.

In a moment, the hundred-meter-high stele was lit up, and the ordinary stele that was brown before turned into a huge blue crystal stele in a blink of an eye, with a crystal clear body and a faint blue light.

Ning Tao was stunned by the fantastic scene in front of him, and he 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 hand after a short pause.

However, Ning Tao only lightly touched the stele to light up the entire stele, and she touched it with both hands, and after she raised her hand, there was no reaction from the hemispherical building.

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

Still nothing happened.

Ning Tao walked over, didn't speak, raised a hand against the stone wall of the hemispherical building, stayed for two seconds and then lifted it up.

A cloud of blue light suddenly appeared from the stone wall, and then expanded in all directions, and in a blink of an eye, the entire hemispherical building was also lit up, emitting a faint blue light, crystal clear.
