The dawn dispels the darkness, a rising sun rises slowly from the eastern sky, and there is a gorgeous glow in the sky.

The breakfast of Ning Tao and Bi Mingzhu is still cactus leaves. Although they are terrible, there is no other option.

After a night's rest, the wounds on Ning Tao's and Bi Mingzhu's feet were scarred, and they didn't feel so uncomfortable walking, so they started again, and their speed was faster than yesterday.

The valley is long and narrow. As you go deeper, more and more plants appear.

At first, Ning Tao and Bi Mingzhu only saw withered and yellow weeds on the hillside. Later, shrubs appeared, one here, one there, and some more than a dozen trees piled up to form a small shrub forest.

These trees give Ning Tao hope. He is eager to see a forest with small animals, rabbits and deer. In that case, he can survive in the forest with Bi Mingzhu, and then plan the next step.

The forest did not appear, but there was a dense shrub forest, large and small, two or three meters high, and the small one meter high, covered with red fruits. Under the dawn, it hung on the branches like a ruby.

"What fruit is that?" Bi Mingzhu excited tunnel.

Ning Tao just looked at it and recognized it: "that's medlar, Solanaceae shrub."

"Can you eat?"

Ning Tao said: "this medlar is a kind of medicinal material in my hometown. It nourishes Yin and Yang and is good for men's kidney. People in my hometown like to drink it in water."

"Then you have to eat more." Bi Mingzhu said.

Ning Tao: "

When is it your turn to eat Chinese wolfberry to tonify the kidney?

However, he still ate a lot, not to tonify the kidney, but to supplement his physical strength.

Many weeds grew in the medlar forest, and he pulled some down.

"Old send, why are you pulling grass?" Bi Mingzhu is curious.

Ning Tao came over with a handful of weeds: "sit down."

Bi Mingzhu sat on the grass and looked at Ning Tao. Her eyes seemed to guess whether Lao song wanted to tell a story, but she didn't say it.

Ning Tao squatted down and took one foot of Bi Mingzhu. Then he padded the weeds on the soles of his feet, twisted them into a simple rope for reinforcement, and made a simple straw sandal in the twinkling of an eye.

Bi Mingzhu now understood what Ning Tao was doing. Without waiting for Ning Tao to greet her, she lifted her other leg, handed a dirty jade foot to Ning Tao and waited for him to make straw sandals for herself.

Ning Tao was inexplicably moved by the posture of raising one leg.

He made a pair of straw sandals for Bi Mingzhu, and Ning Tao himself made a pair of straw sandals and put them on his feet, and then continued to walk down the river bed to the depths of the canyon.

In those days, lotus root silk and cloud shoes were not popular, but now they are reduced to wearing straw sandals. There is no difference.

The afternoon sun was strong, and Ning Tao and Bi Mingzhu came to the end of the canyon.

At the end of the canyon stands a big mountain, which is steep and five or six kilometers high by visual inspection. If such a big mountain is placed on the sacred mountain, it is at most a small stone. But here, it is an insurmountable existence. There is no magic power of stepping on the divine cloud, and there is no flying sword instead of walking. If you want to turn over with only one leg, the probability of death and disability is more than 80%.

Until he reached the end of the canyon, Ning Tao didn't find water, and the riverbed of the canyon was interrupted at the foot of the mountain. Its source is on a cliff. From the characteristics of the rock wall, it is not difficult to see that there was a waterfall on the rock wall, but now the flow is cut off, leaving only the rock polished very smooth by water.

Ning Tao came with hope, but the scene in front of him disappointed him.

No forest, no water, just some medlar and cactus, he and dissatisfaction can't last for a few days.

If you want to move on, this mountain has become an insurmountable obstacle. He and Bi Mingzhu don't even have a pair of shoes, water and food. How can they climb such a steep mountain?

In those days, the three realms crossed casually, up to the sacred mountain and down to the yellow spring, and all the people knelt down wherever they went

Think of a fart.

Now it seems that most of those spells are also procedures?

It's like special effects in a movie.

Iron man never flies. His armor is just a prop.

The heaven leaning sword and dragon slaying knife are all plastic. They can't kill people at all.

The real world, a reality explains everything.

Bi Mingzhu slumped on the ground and said in frustration, "old send, don't ask me to climb this mountain. I can't climb it. Don't climb it. You'll fall to death."

Ning Tao didn't talk to her. He walked to the cliff under the waterfall.

"Old send, do you really want to climb?" Bi Mingzhu got up and followed Ning Tao. "Don't go, you'll really fall to death."

"There's something there." Ning Tao said that he also raised his hand and pointed out the direction to bi Mingzhu.

There are several rocks in that place, with a triangular hole in the middle. It looks like a rock falling from the mountain and held it together. There is a gap between the rock and the rock in the middle. There is nothing special. But Ning Tao found that the sunlight did not refract after it was recruited in. It was not an ordinary small hole.

The son sending God used to find holes with earth inkstone, but now he finds holes with experience.

"What's in there?" Asked Bi Mingzhu.

"I don't know. Just go and have a look." Ning Tao said that there was a glimmer of hope in his heart.

When they came to the shed cave, they looked over several half height rocks stacked at the entrance and saw a dark cave, but not a natural cave. The inner wall was inlaid with alloy, but painted black. No wonder there was no light refraction.

"Let's go in and have a look." Bi Mingzhu is a little worried.

Ning Tao thought for a moment: "Pearl, we have to make some preparations to go in. You pick some cactus leaves and medlar, and I'll pick some firewood. We have to have torches and food to go in, otherwise it will be very dangerous."

They split up.

Half an hour later, the two met at the cave entrance.

Bi Mingzhu picked more than 20 cactus leaves, but there was no medlar. There are a lot of medlar in the canyon, but she has no pocket and can't fit it. It's her limit to take more than 20 cactus leaves.

Ning Tao not only broke a large bundle of firewood, but also lit a torch by drilling wood for fire.

"Old send, if you want to eat medlar, I'll pick it for you when I come back. I can't take it now." Bi Mingzhu also specially explained to Ning Tao.

What do you mean I want to eat medlar?

Ning Tao was speechless, but he didn't say anything. He led the way into the cave.

After stepping over the large rocks with several sheds and entering the mountain, the cave becomes an artificial channel. It is about three meters high and about three meters wide. It is a circular channel. Such a channel is certainly not used to run planes and cars, but rather a water diversion pipe. Combined with the dry waterfalls outside, this guess is likely to be true, but there are no other possibilities, such as cable ducts.

There was a thick layer of ash in the passage, and two lines of deep footprints were left where Ning Tao and Bi Mingzhu passed, which also saved the trouble of leaving marks. If there is nothing in it and there is no value of exploration, they can follow their footprints back to the canyon and continue to be a pair of Adam and Eve who eat cactus and medlar.

The channel was straight at first, and then it extended downward obliquely, but the slope was not very large, which was about 30 degrees. It was labor-saving to go down, but it must be very laborious to go back.

After walking for more than 1000 meters, the torch went out. Ning Tao took a new torch with the shrub firewood on his back and continued to walk forward in his hand.

In this way, after lighting three torches, Ning Tao and Bi Mingzhu walked out of the end of the circular passage. The light of the torch diffused away, and a huge water tank, hundreds of meters high and hundreds of meters wide, as well as huge pumps and pipes for pumping water and ladders for maintenance came in front of it.

The sink and pipes are made of alloy, free from rust and well preserved, but the water pump and pipe in the sink are not, and they have long been rotten. There is a pile of rust next to the pump and under the pumping pipeline, and even the rust is weathered.

Fortunately, the ladder is also made of alloy material. It doesn't rust, but there are signs of weathering. Otherwise, Ning Tao and Bi Mingzhu can't climb up with their bare hands.

"Old send, this place is so strange." Bi Mingzhu sighed.

Ning Tao said: "there is a sink and a pump for pumping water, which shows that this place is inhabited. I guess it is likely to be an underground city. There are ladders there. Let's climb up and have a look."

"Yes." Bi Mingzhu answered.

Ning Tao came to the ladder with a torch and stretched out his hand. Some dust fell from the ladder, but it was still strong. There were no signs of slag falling, shaking and so on.

Then Ning Tao made some preparations. He opened the firewood bundle on his back, sandwiched the cactus leaves in Bi Mingzhu's hand among the firewood, tied it again with straw rope, and finally carried the firewood bundle on his back.

These cactus leaves are not only his and Bi Mingzhu's food, but also his and Bi Mingzhu's life. They can't be left behind.

"Pearl, you climb up with me. Be careful." Ning Tao gave an advice.

Bi Mingzhu simply leaned over and scented Ning Tao's cheek: "be careful, too."

Ning Tao's heart was a little hot. He had a hunch that he had to tell her a story next time he had a full stomach and rest.

Ning Tao bit the torch in his mouth and climbed up the ladder.

It seems like a small thing to climb a ladder, but it's actually very dangerous. Ordinary people, a 100 meter high ladder in the real world, go up and down, how many people dare to climb? If you don't pay attention, you will fall down and die. Moreover, I don't know how long the ladder has been built. It's hard to guarantee that there is no looseness or anything.

This is the real situation after freshman. There are no dazzling special effects or exaggerated magic tools. Ning Tao can only use his hands and feet. The danger of killing an ordinary person can also kill him. So he climbed very carefully, but he didn't dare to be too slow, because the torch wouldn't burn all the time.

This fucking real world.

The 100 meter ladder soon came to an end. Ning Tao climbed up and ignored the situation outside the sink. Then he turned around and stretched out his hand to pull the Bi Mingzhu.

Bi Mingzhu also climbed up.

Ning Tao then held up the torch and walked to the edge of the sink platform.

When they reached the edge of the sink platform, the fire was emitted, and part of the scene in the dark space came face to face. The two people standing side by side were stunned on the spot.
