Eight hundred and ninetieth chapters underground city
"You, the most ancient gods in the world of cultivation, should stay away from our spaceship when they see it!" Xueyi said with a proud look on her face.
"But, you became my prisoner." Zhao Yuan looked at Xueyi's flawless face and said with evil intentions.
"I am only one of the top ten masters of the lower-level awakened humans. Among the entire awakened humans, I am an insignificant existence. If you meet our mechanical warriors, I'm afraid..." Xueyi was completely unaware of Zhao Yuan's naked gaze.
, During this time, she has become accustomed to Zhao Yuan being nonsensical at certain times, and she also knows that Zhao Yuan usually only talks and does not take action.
"Mechanical warrior?" Hearing this name, Zhao Yuan felt an inexplicable feeling of extreme danger.
"Yes, mechanical warriors, we awaken the legendary warriors of mankind!"
"Haha, the legendary warrior. Since it is a legendary warrior, you must have never seen it before."
"Zhao Yuan, if you encounter a mechanical warrior, the best way is to escape as soon as possible, don't take any chances!" Xueyi looked at Zhao Yuan with a serious face.
"Is it really that powerful?" Zhao Yuan was stunned.
"Zhao Yuan, last time you mentioned that there is a cultivator on earth like Hou Yi shooting the sun. I suspect that he is not a cultivator, but a mechanical warrior."
"Hou Yi is a mechanical warrior..." Zhao Yuan suddenly couldn't open his mouth from ear to ear.
"I'm not completely sure, but from the weapons he used, we can preliminarily judge that he was a mechanical warrior in the early days of our awakening of humanity. In the allusions of our awakening of humanity, there are biographies of some mechanical warriors that are very similar to Hou Yi's shooting of the sun.
.”
"Maybe...could it be that Pangu opened the sky and Nuwa mended the sky, but they were all mechanical warriors."
"Haha, you are overthinking. Most of them are gods, but occasionally there are a few mechanical warriors, which can make ancient humans mistakenly think that they are also gods." Xueyi said with a smile.
"I see...wait a minute, are you saying that awakened humans began to operate on the earth tens of thousands of years ago?"
"Yes. According to the historical records of our awakened humans, tens of thousands of years ago, early awakened humans set foot on many star fields, and the Milky Way has very clear records. I personally guess that the primary civilization of the earth,
It should have been brought there by awakened humans."
"No wonder, no wonder..." Zhao Yuan murmured to himself.
"What's the matter?"
"In some prehistoric civilizations on Earth, many murals show that aircraft and aliens wearing space suits landed on the Earth. It seems that it is very likely that you awakened humans have really reached the Earth."
"Well, this is very likely. Of course, we can't rule out that other human civilizations have reached the earth."
"Okay, okay, what the hell, I'm going to dig a tunnel. If we can't find a way home tonight, we'll have a wedding." Zhao Yuan held Xueyi in his arms, holding his hands in his arms.
She pinched her face.
"Didn't you say you wanted me to do it?" Xueyi's neck turned red and her voice was so low that she couldn't even hear her.
"Yes, because now I feel that you are very willing."
"ah……"
Xueyi was too shy to look into Zhao Yuan's eyes.
"Okay, I'm going."
When Xueyi looked up, Zhao Yuan had disappeared out of thin air. The air was still filled with Zhao Yuan's strong manly smell, no, it was the smell of sweat.
Half an hour later, Zhao Yuan appeared in front of Xueyi, dripping with sweat.
"Your suspicions have been ruthlessly confirmed." Zhao Yuan said with a bitter smile.
"Really a metal crust?"
"Yes, I dug three places in a row. After digging to the same distance in the three places, they were all covered with metal crust. It seems that the only way to open the metal crust is to use violence." Zhao Yuan sighed.
"Then dig it."
"Will it damage the structure inside?" Zhao Yuan was a little worried.
"If the interior of this planet is hollowed out, then there should be a huge underground city underneath. Digging a hole should not have any impact, unless you happen to dig into the core control room."
"I won't be so unlucky. Xueyi, guess, is there anyone alive inside?" Zhao Yuan asked.
"No."
"Why are you so sure?" Zhao Yuan was stunned.
"Hollowing out a planet is obviously a defensive posture. In other words, the humans here have experienced an external invasion. If they survive the enemy's invasion, they will not live there for a long time.
Underground, and judging from the current situation, there is no trace of human activity on the ground, so it is enough to prove that they have all been killed."
"All the people on the planet were killed?" Zhao Yuan felt inexplicably heavy.
"The biggest difference between ordinary humans who have not broken through the space barrier and cultivators is that once they encounter an attack from outer space, there is no third option except surrender or death. It is for this reason that the early awakened humans,
Traveling around various planets inhabited by humans, spreading the fire of scientific and technological civilization, allowing them to gradually have the ability to break through space barriers." Xueyi looked gloomy.
"Maybe a miracle will happen." Zhao Yuan laughed twice.
"hope."
Xueyi nodded, but she seemed to know too many such tragedies, and there was no expression of expectation for a miracle on her face.
Zhao Yuan didn't say anything more, and returned to the entrance of the hole where he started digging, jumped in, and started digging.
Compared with the initial excavation, the efficiency of digging metal is much lower. Even if Zhao Yuan is already a half-immortal, he still has to expend a huge amount of energy in the face of high-tech smelted alloys. Fortunately, Zhao Yuan has
The number of crystals is countless, he only needs to refine the crystals and use the energy of the crystals for excavation.
If you rely solely on the raw power of the human body and the tyrannical strength of Zhao Yuan's training in "Ten Thousand Enemies", it will not be possible to dig through the alloy earth's crust overnight.
It took Zhao Yuan two hours to dig through the metal crust, which was dozens of feet thick. If he hadn't experienced it himself, he would not have dared to imagine how much manpower and material resources it would have cost to build this huge underground project. You know, building these
Underground Engineering is not a cultivator, but an ordinary human being.
"Click!" With a sound, a hole was finally dug through the silver metal shell, and a ray of warm light drove away the darkness in the tunnel.
Zhao Yuan held his breath and did not make the slightest sound.
Although Xueyi said that there would be no one left in the underground city, Zhao Yuan still held on to the last glimmer of hope.
In order to avoid disturbing the residents below, Zhao Yuan was very careful in his last excavation work. The hot immortal fire melted the metal shell. Slowly, slowly, a round hole with a diameter of one meter was melted out of the metal shell.
Through the round hole, Zhao Yuan peered into a huge underground world.
This is a breathtakingly quiet underground world.
At the same time, this is also an underground world full of life.
Bright lights.
Green trees.
No.
There was not a single pedestrian in this huge space, the spacious and bright streets were empty, and the atmosphere seemed particularly strange.
This should be a city of steel, but not everything you see is steel. In many places, you can’t even see metal.
Vibrant vitality and a strange atmosphere coexist in a huge underground space without any sense of dissonance.
Zhao Yuan also took Xueyi underground.
As Xueyi, an awakened human who has seen a lot of the world, she couldn't help but be amazed when she saw this huge underground world.
At this time, Zhao Yuan inexplicably thought of those ancient buildings on the earth.
Compared with this huge underground ruins, things like the pyramid hanging gardens are not worth mentioning at all.
What shocked Zhao Yuan the most was that this huge underground city seemed to be still operating normally. The artificial sunlight on the top and the street lighting system, the automatic sprinkler system on the ground, and even every other section of the street
At some point, some very sci-fi-looking vehicles will stop and drive away, but there will be no passengers on them.
You can imagine how prosperous this underground city was back then.
"What level can the level of science and technology here reach?" Even Zhao Yuan, who is not scientifically illiterate, can feel that the science and technology here is way ahead of the world.
"Level 2." Xueyi kept observing the surrounding infrastructure.
"Is this only Level 2?" Zhao Yuan looked blank.
"Yes, level two is not enough for level three." Xueyi nodded and replied to Zhao Yuan with certainty.
"I really want to visit the place where your eighth-level civilized humans live." Zhao Yuan said with a bitter smile.
"You can't see it." Xueyi said calmly.
"Why?"
"No cultivator can enter the residence of awakened humans."
"Never?"
"This..." Xueyi's face seemed to be a little loose.
"Have any cultivators been there?" Zhao Yuan immediately noticed the expression on Xueyi's face.
