Courtyard House: Why is my time-travel experience so shabby?

There was no light, no wind, and no sound in the black fog. It was so cold and quiet that it made people shudder.

The further down they went, the lower the temperature became. Even the rock walls gradually turned into solid ice. Even Du Weiguo, who was not afraid of cold or heat, felt uncomfortable with the cold.

Not only that, the further down you go, the greater the concentration of volcanic ash becomes, the thinner the air becomes, breathing becomes difficult, even movements become sluggish, and it feels like being stuck in a quagmire.

After climbing down for more than 300 meters in the black fog, Du Weiguo stopped on a large protruding rock.

"It's at least 20 degrees below zero here, right? It's over 30 degrees outside, the temperature difference is more than 60 degrees. This damn place is really like ice and fire."

He wiped off the thick stone powder adhering to his mask and goggles, glanced at the wisps of breath escaping from the air holes of the mask, and muttered softly.

Du Weiguo certainly wouldn't feel tired. Even in an extremely extreme environment of low oxygen and low temperature, he could still handle it with ease thanks to his abnormal physique.

And the most crucial point is that although this black fog is strange, it cannot block his teleportation ability.

He could escape from here with just a thought, so he was so fearless. No matter what was hidden in the black fog, he was sure he could get out safely.

The reason why he stopped suddenly was because the thing that triggered the "appetite" of the space was not at the bottom of the valley, but right in front of him.

To be precise, there was a huge and deep cave below the side of the stone where he was living. The source of the throbbing space was in this cave.

However, in addition to the clear throbbing, the sense of danger also upgraded, the scalp was tingling, the spines stood on end, and the heart beat like a drum.

"Damn, there are traces of human intervention in such a desperate situation? This is too outrageous. Could it be that this is not a human? Could this be the lair of some non-human race?"

Under the mask, Du Weiguo's expression became very solemn.

At this moment, his vision and perspective were extremely limited, and the stone walls were too thick for him to see through. However, he could still make out that the cave under his feet had many traces of unnatural formations.

This cave is incredibly large, and is shaped like an irregular acute triangle. It is at least 70 meters high and over meters wide, and can accommodate more than a dozen trains running in parallel.

The cave was also filled with volcanic ash, making it impossible to tell how deep it was.

Of course, this is not the point. The point is that the ground and rock walls of the cave are very neat. Although a little rough, they are straight and flat, and it is impossible for them to be formed naturally.

It was obviously dug out by humans, or maybe not by humans.

On both sides of the cave, there are many tall, totem-like stone statues. They are all very abstract and crude, but they exude a desolate and solemn aura.

Apart from this, there were no living creatures in the cave, nor any signs of any biological activity. It was completely silent.

"Could it be that all the creatures that originally lived here have died out?"

Du Weiguo wiped off the stone powder that was quickly attached to the mask, silently feeling the urging of the space, sighed helplessly, and muttered to himself.

"Oh, forget it. Now that I'm here, I have to go in even if it's a dangerous place."

After he finished speaking, he no longer hesitated and suddenly jumped down from the boulder. When he was in mid-air, he used the force of the Nine Nether Rope to swing and leaped into the cave like an eagle.

There was a thick layer of volcanic ash on the ground, which felt soft and inexplicably comfortable when stepped on.

The moment he fell into the cave, Du Weiguo immediately took out his custom-made pistol and fired a carved bullet into the depths of the cave.

"Hey~"

The strange whistling sound was so enchanting that it sounded like the wail of a banshee. When he counted to between 2 and 3, the whistling sound of the carved bullet disappeared completely.

"Fuck, this is bullshit~" Under the goggles, Du Weiguo's eyes widened in surprise.

You know, the custom-made pistol with carved bullets has terrifying kinetic energy, with a muzzle velocity of up to 1380 meters per second, which is more than four times the speed of sound.

If it takes 3 seconds, theoretically it can fly more than 4000 meters. Of course, this is impossible. Under normal circumstances, the flight limit of the carved warhead is 3200 meters.

Even if the resistance increases due to the volcanic ash, it can still fly at least 1500 meters.

Until the kinetic energy was exhausted, the carved bullets did not encounter any obstacles. In other words, the straight-line depth of this cave exceeded 1500 meters, which is simply incredible.

He quickly changed the angle and fired a few more shots, not believing in evil, but the results were almost the same.

Du Weiguo was stunned. He was extremely sure that he was in an extremely huge triangular passage.

So the question is, what is the volume of a triangular object that is 1500 meters long, 70 meters wide, and 100 meters high?

Answer: I don’t know.

Du Weiguo had basically returned all the mathematical knowledge he had learned in his two lifetimes to his teacher. He counted on his fingers for a long time but still couldn't figure it out.

All we know is that it is huge, bigger than we could imagine, and 1500 meters is only the limit of the carved warhead, not the limit of the passage.

"Damn, this can't be done by human power. Could this be the lair of some ancient evil god? Or a gathering place for aliens? Or maybe there is an alien spaceship hidden in the cave."

Du Weiguo's mind was full of thoughts and he started to have all sorts of wild ideas.

"Damn, this place is so damn evil. Let's explore further. If it doesn't work, I'll retreat. No matter how great the opportunity is, it's not as important as my life."

At the same time, he was a little hesitant, but secretly encouraged himself in his heart.

"Puff~puff~"

In the cave that was as silent as a tomb, Du Weiguo waded through the volcanic ash that was above his calves, walking slowly but actually fast.

After walking about 500 meters, he stopped again and fired a few shots forward, but still did not hear the sound of bullets hitting obstacles.

On the rest of the journey, he would fire a few bullets every time he walked a certain distance. After repeating this five times, he finally heard a barely audible muffled sound.

"Huh~ More than 4 kilometers in a straight line, finally the end."

Du Weiguo let out a long breath and felt relieved.

"Hmm~"

After a few minutes, when he heard a sound of metal collision, he stopped abruptly and his brows suddenly raised.

At the end of the long passage, there is a huge metal door, which is 6 stories high and more than ten meters wide. Du Weiguo stands at the door, as small as an ant.

There was a thick layer of volcanic ash on the metal door, but with his eyesight, he could still see the blue-gray base color and the intricate patterns carved on it.

"Click, click, click~"

Du Weiguo took out a Demon Shuttle and tentatively poked it at the door. Volcanic ash fell off and a low and dull metal knocking sound was heard.

It was obvious that the metal door was solid and very thick.

His eyes became more serious, staring straight at the metal door in front of him, and even reached out to touch it.

The material of this door is very special. It looks somewhat like bronze and has a very high hardness, comparable to steel. The most important thing is that its temperature is incredibly low and extremely cold.

Even through the high-tech gloves of MI6, he could still feel a bone-chilling chill. Du Weiguo knocked hard again, but the metal door didn't budge, and the rebound made his palms hurt. He was a little shocked:

"Damn, this door must weigh thousands or even tens of thousands of tons. Even if there are tracks and rollers underneath, it would probably take thousands of people pushing it at the same time, right?"

"Although this door is big enough, it can't hold so many people, right?"

Du Weiguo did not act rashly and directly test the metal door with the floating knife. Instead, he took a few steps back and looked at the door carefully.

The pattern carved on the door is not a concrete object, but more like many totems spliced ​​together. It is very abstract and there is no clue.

There are no mechanical devices nearby, but that makes sense when you think about it. A gate of this size cannot be controlled by a mere mechanical device.

The door is double-door and closes tightly.

The gap between the two door panels was measured in millimeters, and the inside was blocked with stone powder. Even with Du Weiguo's sharp eyesight, he couldn't see it clearly.

Du Weiguo stared at the intricate patterns on the gate for a long time without making any sense, and felt his eyes were blurry.

He looked away dejectedly and complained weakly.

"A desperate place beyond human reach, an incredibly long corridor, and a huge bronze door. This plot is somehow familiar to me."

"Fuck, this isn't a tomb, is it? Grave Robbers' Chronicles? Can you please stop barging in?"

In fact, it’s not that there are no clues at all. One thing is particularly clear: the "food" that Space desires must be behind this door.

However, everyone who has read the novel knows that wherever there are rare treasures, there must be desperate places, and there are also monsters and beasts guarding them.

According to Du Weiguo's experience, the process of helping the space "beg for food" is never easy, and he will always encounter strong enemies.

The strongest enemies he had ever encountered, Lilith, who ranked first, and Xiang Pan, who ranked second, were both drawn out by the "food" in space.

Now, Du Weiguo took great pains and finally got rid of Masal and his gang of evil spirits, and basically subdued the beasts of the Kui Cult.

However, there are still many problems that need to be solved urgently.

He must go back as soon as possible to deal with the dragons and insects in the Demon Mist Mountain, the old worm spirit, the leeches, the trip to Citibank, and the Sijiu City.

At this critical juncture, Du Weiguo hesitated, as he really didn't want to provoke another powerful enemy.

However, at this moment, the system space was like an ignorant naughty child, rolling around and urging him, and the tremors in the sea of ​​consciousness were getting stronger and stronger.

"Fuck you, you bastard system! You'll kill me sooner or later! Damn it! The brave ones will die of overeating, and the timid ones will die of starvation. Let's fight!"

After a long struggle between his conscience and desire, Du Weiguo gritted his teeth and cursed, then raised his hand and the Floating and Sinking Knife was already in his hand.

In the dark space, a dazzling dark golden blade light suddenly flashed.

"Chi~"

The Floating and Sinking Knife would never let Du Weiguo down. The next moment, it scratched a deep mark of more than three inches on the surface of the metal door.

The process is not smooth, and there is a sense of sluggishness.

With just this one move, Du Weiguo instantly determined that the hardness of this metal door was almost as good as that of high manganese steel.

He lifted the Floating and Sinking Knife to his eyes and carefully observed the blade to make sure it was intact, without even a scratch, before he felt relieved.

"Swish, swish, swish~"

Du Weiguo no longer hesitated. He used all his strength to swing the Floating and Sinking Knife into a dazzling ball of light and chopped it hard at the metal door.

"Danglanglang~"

Large pieces of unknown metal kept sliding down and hitting the ground heavily, making bursts of roars.

"Fuck! Fuck! Damn, why is this door so thick?" Du Weiguo cursed angrily while chopping.

At this moment, he felt like he was using a pocket Swiss Army knife to try to dig through a thick and heavy dictionary, and he was working in an oxygen-deficient environment, making the project extremely difficult.

Fortunately, Du Weiguo's physical strength was almost unlimited, and his floating and sinking knife was powerful enough, as he chopped hard without stopping.

Finally, he carved a fist-sized hole at the junction of the two doors.

"Hey~"

The air pressure inside and outside the door was obviously different. The moment it was broken, an extremely fierce gust of wind suddenly blew out of the hole.

How strong was this wind? The thick volcanic ash suspended near the huge bronze gate was instantly blown out into a huge elliptical vacuum zone with a radius of several dozen meters.

But Du Weiguo was very smart. He dodged early and even teleported away, so he was not hit at all.

It was not until half a minute later that the evil wind gradually subsided, and almost all the volcanic ash within a hundred meters in front of the bronze gate was swept away.

And this is not the end yet. It seems that there is some invisible catalyst hidden in this wind.

When the wind stopped, the black fog, which had been suspended and motionless like a pool of stagnant water, suddenly began to become active as if it had received some signal.

The black fog seemed to suddenly come alive, and began to boil and roll continuously, gradually spreading outward.

However, Du Weiguo was completely unaware of all this, because he had already seen through the hole and clearly saw the situation behind the door, and teleported directly in while the wind was still blowing.

Behind the door was an extremely vast open space. The ground was very flat, probably because it had been carefully crafted. There was no volcanic ash everywhere, only thick dust, and no one knew how long it had been falling.

At the far end, about a few hundred meters away, there is a large triangular building that resembles a temple altar and a bit like the Egyptian pyramids.

At a rough glance, there are dozens of them.

The source of the spatial trembling was in the tallest and largest pyramid among them. Seeing this scene, Du Weiguo brushed off the stone powder on his head and face, and his expression became playful.

"The style of these buildings is somewhat similar to the temple on Devil's Island where Lilith is imprisoned. Could it be that this is another prison where the Iron Blood Warriors imprison the cosmic-level strongmen?"

Thinking of the hopelessly powerful Lilith, Du Weiguo felt fear in his heart, but also a burning desire arose.

The Earth is not an isolated island, and humans on Earth are not the only intelligent race in the universe.

Du Weiguo is now the king and the best in the world, but this is only limited to the earth.

If placed in the context of the universe, he is just an insignificant shrimp, not even a fart.

As long as he continues to live, Du Weiguo will sooner or later come into contact with those powerful people outside, there is no escape.

After taking a few long, deep breaths, Du Weiguo took long strides and walked towards the pyramid.
