The water problem is solved, now only the food problem remains. If you eat cactus leaves and wolfberry every day, it is not a problem after all. Moreover, cactus and wolfberry grow in the canyon. It will be very difficult to climb up from the metal pipe. Walking a long distance just to eat something is not an option after all. .
But the hope of finding food in this underground base seems slim.
When the group of 10 had walked about four or five kilometers, a brown rock wall appeared at the end of the two beams. There are also water drops dripping down the rock walls, so that parts of the rock walls appear very wet and moss grows on them.
Bi Mingzhu said excitedly: "I just said that this underground base must have an edge. This is the edge. There is still water here. I will fill it with water."
Ning Tao came to the foot of the rock wall. Bi Mingzhu filled the small puddle under the rock wall with water, while he collected moss from the rock wall.
Moss is rich in green pigments and carotene, and also has certain anti-inflammatory properties. It can be eaten as a snack in an environment without food.
He washed a small piece of moss and put it in his mouth to chew. The taste was a bit astringent, but not unpleasant.
Bi Mingzhu asked curiously: "Can this small plant be eaten?"
Ning Tao said: "It's called moss, and it's edible. You should eat some too, for a change."
Then he handed Bi Mingzhu a small piece of moss, and Bi Mingzhu put it in her mouth and chewed it, then said with a smile: "It tastes pretty good. It seems we have found another granary."
Ning Tao smiled: "It's not enough to eat this for a long time. Let's continue to explore. Maybe we will make better discoveries."
"Then should we go back the way we came or go forward along the rock wall?" Bi Mingzhu couldn't make up his mind.
Ning Tao thought for a moment: "Let's return to the central route diagonally. The people who built this base probably won't make a fuss in the edge areas. The important facilities should be in the middle area. If we want to find something, we have to Take the middle ground.”
"Well, it's up to you." Bi Mingzhu said.
She found water and food, although it was just moss, but it also gave her a lot of hope, so she is very happy now.
Ning Tao led Bi Mingzhu diagonally toward the center of the underground base, continuing to explore along the way. Along the way, he knocked on several metal cabinets and found more cuckolds, but he already had a cuckold on his head, and he couldn't wear it again if he wanted to.
Not far after returning to the central area, a tree root emerged from the ground and extended towards the apple tree.
The tree roots emerging from the ground are very thick, thicker than Ning Tao's waist. It stretches forward, twisting and turning, 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 when he was alive. For some reason, the moment his fingers touched the roots of the tree, a strange feeling arose in his heart. It felt... like he was touching himself!
"Laosong, the roots of this tree are dead. Half of the apple tree that gave us new life is alive, 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 believe we will definitely find fresh tree roots."
As soon as he finished speaking, a blue light suddenly flashed through the tree roots. At that moment, the tree roots in front of him seemed to turn into blue crystal clear crystal.
The blue light was so intense that the two green heads on Ning Tao and Bi Mingzhu's heads
The hat's lighting fixtures were overshadowed. However, it lasted very briefly and disappeared in less than a second.
"Just now... that blue light..." Bi Mingzhu wanted to say something, but the words didn't come out. The sight was too shocking.
Ning Tao was still stunned, and it took more than ten seconds to come back to his senses. He said: "It must be that machine. It weaved another virtual universe and then sent it to the apple tree."
"We activated the machine. Is this the meaning of the apple tree giving us new life?" Bi Mingzhu was confused.
Ning Tao said: "The person who created that machine should have thought about the arrival of seeds like you and me, but we don't know what his purpose was. Let's go, let's go forward, let's get to the apple tree Look at your feet."
After discovering the tree roots, they could walk to the foot of the apple tree without getting lost. However, the two of them were confused about what was going on there and could not guess at all.
Ning Tao and Bi Mingzhu walked forward along the tree roots. They didn't go far, and just a few minutes later, another group of blue light flew past the tree roots. The darkness in front was dispersed by blue light, revealing a large number of machines and instruments, a decayed and messy scene.
Just walk and walk like this, and when you are tired, you will take a break to drink water and sit on the roots of a tree. When you find something worth studying, stop and look at it and think about it.
Anyway, until now, Ning Tao felt that he and Bi Mingzhu were the only two people in this world. He had plenty of time and was 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.
Where the bright beam of light reached, it was a large area of large and small tree roots hanging down from the rock formations thousands of meters high, like a large net, covering a large space layer by layer.
Half of the tree roots are alive and half are dead, which can be distinguished at a glance 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 a hundred meters tall, but I didn't expect its roots to be so developed, penetrating the soil and rock walls, hanging down for a thousand meters, and taking root underground.
But there seems to be no need to be surprised. An apple tree that contains hundreds of millions of virtual universe worlds and has two new fruits is itself an extremely magical and mysterious existence.
"There..." Bi Mingzhu suddenly pointed to a place among the roots of the tree and said with great excitement: "Old Sang, look there!"
Ning Tao looked in the direction she pointed, looking through the layers of large and small tree roots, and then saw a building hidden among the tree roots.
The building was also in the shape of a hemisphere, with a huge stone tablet in front of it. At first glance, it felt like a tomb.
grave
How could there be a tomb in such an underground base
Ning Tao was filled with curiosity, and he couldn't help but walk towards that place.
Bi Mingzhu followed closely: "Laosong, be careful, I think that place is a little weird."
"Do you think it looks like a tomb?" Ning Tao said as he walked.
"Grave?" Bi Mingzhu shook her head, "I think it is like a temple."
Ning Tao's lips moved, but he still gave up the discussion. He and Bi Mingzhu are from three realms in different universes.
Lord, different races have different cultures. Maybe in the universe dominated by Bi Mingzhu, those large and small temples are like tombs.
There is absolutely no point in discussing this at this time.
The two of them soon came to the tree root network. Just as they were about to get in, another group of blue light came from the thick dead tree root. At that moment, all the tree roots were lit up and turned into blue crystal tree roots one after another. The scene was full of mystery and extremely spectacular.
However, this spectacular sight only lasted for a second and then disappeared. Not even a trace was left on the roots of the tree or in the surrounding space. It's so bright, but it hasn't changed anything.
"Laosong, where do you think that ball of blue light went?" Bi Mingzhu asked.
Ning Tao thought for a moment before saying: "Did you and I both think that the virtual universe 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 a tomb and said: "I suddenly felt that the virtual universe weaved by that machine was sent into that building, but I'm not sure. Let's go in and have a look."
Bi Mingzhu responded, and then followed Ning Tao into the tree root net.
The building hidden among the tree roots got closer and closer, and Ning Tao realized that it was even bigger than what he saw outside. The stone monument is at least a hundred meters high, and the hemispherical main body behind it is also two to three hundred meters high, which is much larger than a football stadium.
They said they were going in, but when they arrived in front of the hemispherical building, the two of them frowned in unison.
This hemispherical building doesn't even have a door, not on the main body of the hemisphere, nor on the stone monument standing in front.
"How can we get in if there is no way?" Bi Mingzhu looked depressed.
Ning Tao thought for a moment and said, "Maybe we can try the previous method, maybe it will work."
After saying that, he put his hand on the stone tablet.
The stone tablet remained motionless, but when he opened his palm, a blue light suddenly lit up from the place where his palm touched, and then expanded in all directions.
In a moment, the entire stone stele, which was hundreds of meters high, was lit up. The ordinary brown stone stele before turned into a huge blue crystal stele in the blink of an eye, crystal clear and emitting a faint blue light.
Ning Tao was so stunned by the fantastic sight in front of him that he could stand motionless 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 and pressed them against the stone wall. After a brief pause, she raised her hands.
However, Ning Tao only touched the stone stele lightly and lit up the entire stone stele. However, she touched it with both hands. After she raised her hands, there was no reaction on the hemispherical building.
"Why can't I?" Bi Mingzhu was a little unconvinced and simply clapped her hands twice.
Still no response.
Ning Tao walked over without saying a word. He raised a hand and placed it on the stone wall of the hemispherical building. He stayed there for two seconds and then raised it.
A ball of blue light suddenly appeared from the stone wall, and then expanded in all directions. In the blink of an eye, the entire hemispherical building was lit up, exuding a faint blue light, crystal clear.
