I don't know how long I slept, Zhao Zihan woke up, felt an itch on his face, like something was gently brushed, and touched it with his hand, it was Yao Yao's hair.

"So you woke up early, why didn't you wake me up?"

Zhao Zihan opened his eyes and saw Yao Yao's hazy shadow, as well as the glimmer of two big eyes.

"Well, I didn't call you, let you rest a little longer. Yao Yao said.

"I'm awake alone, I'm so scared!"

Zhao Zihan was speechless and did not speak.

There was water and food in the cloth bag, and when I took it out and pinched it, it was air-dried beef, and there was a faint fishy smell.

"Grab a bite to eat and keep walking. There's beef here. ”

Zhao Zihan groped for Yao Yao's hand and gave her a piece of beef.

Yao Yao took a bite and said, "This is yak meat." ”

Zhao Zihan didn't squeak, and said in his heart: No wonder the taste is a little different.

Yao Yao "felt" Zhao Zihan's extremely faint figure in the dark, looked at the two faint starlight, and thought to himself: These are his eyes, he is a person who can be trusted!

It's a wonderful world.

I have only known him for such a short time, but in this boundless darkness, he gives me the feeling that I have known him for a long, long time.

From now on, he may be a friend I can entrust to life and death.

At this time, she completely forgot her fear and pain, but she was happy to make a friend like Zhao Zihan.

Half a moment later, Yao Yao grabbed Zhao Zihan's leg with one hand and said, "Zhao Zihan, let's continue." ”

The two of them groped forward again, and after a while, they felt that the ground was getting wetter and wetter, and there were even small droplets of water falling on their bodies every once in a while, which was very cool.

"Hold on, Yao Yao, there should be an exit not far ahead. Zhao Zihan cheered Yao Yao up, thinking to himself: She is a strong girl.

I don't know how long I climbed like this, but when the two of them were exhausted, they felt that they touched a platform again, and there was a faint sound of wind on both sides.

The feeling of fresh air wafted through the air, and breathing became much easier.

Yao Yao once again snuggled up to Zhao Zihan and gasped for breath, and her hands naturally grabbed his short placket.

Hmm, you should have climbed out of the abyss, you can try the torch.

Zhao Zihan took out the pine branch flint, and with a "click" sound, a spark appeared! Soon the torch had been lit, and Yao Yao screamed happily.

Then, two people, you look at me, I look at you, pointing at each other and laughing: hahahahaha......

It turned out that in addition to their eyes, Zhao Zihan and Yao Yao's faces were stained, their whole bodies were wet, and their bodies were covered in gray mud, they were simply two gray people!

Yao Yao's pale white plain skirt almost turned black, especially on her chest, and the bulging black was particularly conspicuous......

Yao Yao looked at Zhao Zihan and laughed for a while, then looked down at himself again, and said with a smile: "Two big clay people, no, two big savages!"

Zhao Zihan had already stood up and observed, this was a small platform ten meters square, and there were exits on both sides of the platform.

Which way to go?

A closer look at the imprints underground, I saw faint, not very old drag marks, which were exactly the same as the ones I had seen earlier, the marks left by an unknown monster.

Zhao Zihan couldn't help but feel a chill in his heart, but at this time, what was the use of being afraid?

Let's go to the side first.

Ziyue and Wei Mingcheng don't know what's going on? Where are the two of them?

Thinking in his heart, he picked up Yao Yao and walked towards the left exit, and only twenty or thirty meters walked before a huge space appeared, no, this is a very big house.

He was suddenly so frightened that his body shook, and the torch almost fell, almost giving up Yao Yao and turning around and fleeing.

Yao Yao said, "Ah...!" The ground screamed, his arms clenching at each other, and his long screams echoed through the vast space.

...... Here, it's terrifying!

A lot of bones, a lot of human skulls! There are many heads of unknown beasts......

...... It's so weird here, too... How could these beast wreckage be stacked so neatly?

Has anyone ever lived here?

Cannibals?

Thinking about it, Zhao Zihan felt a cool swishing from head to toe, and couldn't help but feel creepy again, and he had the courage to help Yao Yao with one hand, walked to the side of a pile of white bones, looked at the neat white bones and narrowed his eyes, as if he was thinking about something far away.

Picking up the torch, he shook it tremblingly, and there seemed to be no living thing in the huge room. However, something even stranger was seen in the firelight...... Seems to have a huge stone bed?

Zhao Zihan subconsciously helped Yao Yao to walk over, and saw a neat row of huge stone beds.

“1，2，3，4，5...... There are five of them, three big and two a little smaller..."

"Oh my God, what is this?"

Yao Yao pointed and counted, and said to Zhao Zihan, his leisurely tone seemed to send out an eternal question.

Although there is a faint amount of dust on it, you can still see the polished surface...... This is the mark of a living creature that has been used for a long time......

What monsters used to sleep here?

There are also traces of apparently suspicious activity that cannot be described in words.

But there is no exit from the four walls here, and the whole space is filled with a strange smell, which gives people a very bad feeling...

"There's no more passage here, let's get out. Zhao Zihan looked at the frightened Yao Yao and said.

Walking through the small platform that he had just entered, Zhao Zihan helped Yao Yao into another entrance. After walking for about ten meters, a huge space appeared, which seemed to be ......

"Wow! This is ......"

"Ancient human planes! so many..."Yao Yao said in amazement.

Although most of the rows of metal monsters were in tatters, and many of them were just piles of wreckage, lying on the ground due to the erosion of time, they could still clearly identify the appearance of the plane.

Yes, there are some small planes on the side, which should be the drones mentioned in ancient books, as well as various models of "robots" that have been damaged by the wind.

Could it be that the robots made by ancient humans were ready for war?

With a stomach full of questions, Zhao Zihan approached a relatively complete "strange bird" and found that these planes were obviously more exquisite than the one in the Lancheng Collection.

If it is not damaged, the entire fuselage should have a particularly graceful arc and a particularly streamlined shape......

Ancient humans are amazing! This thing must be beautiful......

Following the passage in the middle of the rows of plane wreckage, the two men slowly walked forward, passed through a very wide "door", and entered another space, and suddenly opened their eyes widen again.

Three large black egg-shaped objects were placed here, intact, unbroken, three stories high, glowing with a cold, mysterious sheen......

Zhao Zihan numbly stretched out his hand and knocked on it, making a dull "dong" sound, and couldn't help but touch it again, it was cold... The feeling of non-gold and non-iron.

What is it?

Judging by the degree of decay of the space, the peeling walls and the weathered concrete on the ground, this should also be a relic of antiquity.

But why are these giant eggs showing no signs of weathering and damage?

Zhao Zihan's mind flashed the picture of Professor Huang Gusi of the Demon Court Archaeological Institute coming to Lancheng to give a lecture:

...... The spaceships built by the ancients even reached the moon, or beyond. Ancient humans are trying to explore the mysteries of the starry sky and the boundaries of the universe.

Some of the more developed places may even have secretly created "time shuttles", and they are looking for entrances to the space-time passages.

......

Is this the "spaceship" that the ancients used to fly to the moon or even more vast space? Or is it the "time shuttle" that they used to travel through the "passage of time and space"?

Were the ancients really able to travel through the universe, or even through time and space?......

Otherwise, how can we explain that these domes have not weathered and dissolved after such a long time?

How can this big egg fly but it doesn't bother, the ancients can create so many strange things, what's so strange about it being able to fly?

But in my dreams, I also traveled from the Earth Star to other interstellar trips, and I didn't sit on such a thing.

Zhao Zihan thought for a while and looked at Yao Yao, she seemed to be sleepwalking, with a pair of big eyes that were very confused...... She must also have a lot of questions, but how can I solve her doubts?

There are still some traces of movement here, on the ground, on the rock wall...... Or did the monsters that existed in that space once linger here for a long time?

Zhao Zihan took a closer look, this is also a dead end, only the entrance, the top is not high, it is an upright rock wall, and it is simply whimsical to climb.

Gently tugging Yao Yao, the two of them returned to the same way, the torches were about to burn out, and there was a burning sensation in their hands, so Zhao Zihan had to take out a pine branch again and light it. There is only one pine branch left, which is troublesome!

Fortunately, a wide stone staircase was found behind the wreckage of several planes, and he helped Yao Yao to quickly walk up the stone steps.

After walking about a few hundred steps, it is still impossible to know where the long stone steps lead, but the direction is upward. Since it is upward, it should not be wrong, no matter how high this mountain is, there will always be an end.

There are also vague footprints on this stone step, human footprints.

Who has been here? Ziyue and Wei Mingcheng?

Zhao Zihan was excited in his heart, and then shouted loudly: "Ziyue ......!"

The sound came far away, and dust trickled down the rock wall, but no one responded.

It seems that she is not here, so where did she and Wei Mingcheng go? I wonder what happened to the two of them? Are they still alive?

With a "boom", a stone wall on the edge of the stone steps suddenly collapsed, and Zhao Zihan hurriedly picked up Yao Yao with one hand and dodged the rolling stones.

"It's ...... inside!" Yao Yao stretched out her hand and shouted.

When I looked at her, I saw a "door" between the collapsed rock walls, and there was a hole in it.

Zhao Zihan walked over, only to reach the entrance of the cave, but the torch in his hand snorted, and suddenly burned vigorously, the tongue of fire deviated to the direction of the cave, he hurriedly stopped, stood at the entrance of the cave and stopped.

In the firelight, two men in yellow clothes could be seen lying on their backs on the ground, their hands touching their throats, and their eyes protruding......
