The thief was shocked to watch.

Others can't see Tai Sui's action clearly, but the thief is a thief after all, although he can't see through what kind of doorway this palm implies, but he can also see how subtle this palm is.

In fact, most of the time, Tai Sui disdains to use this kind of small skill, he is better at opening and closing the number of roads, and likes to go straight, because too many skills will affect the speed of the shot.

Therefore, the thief thought that Tai Sui's strength was mainly reflected in his physical fitness and nerve reflex speed, and as for his martial arts attainments, it was just like that.

But at the moment, this palm is really not a joke, this martial arts attainment can definitely be regarded as a master among masters.

Just because Tai Sui doesn't bother to use tricks doesn't mean he doesn't have them.

"The door opened." Tai Sui said to the thief saint.

Only then did the thief come back to his senses, he looked down at the crack on the ground that had been broken by Tai Sui, and frowned slightly: "Didn't I tell you not to destroy it casually." ”

Tai Sui was a little puzzled: "I deliberately dispersed my strength when I was stepping, but I didn't expect that the material of the ground was different from what I imagined, and if it was a stone floor, it would never be broken." ”

Indeed, the thief also thought that the ground was made of stone, but it wasn't until Tai Sui stepped out of a crack that the thief found that the ground was actually metal.

Tai Sui and the Thief Saint crouched down almost at the same time, illuminating the cracks in the ground with the valve lights.

The material of the ground is a bit similar to pig iron, extremely hard, but very brittle, and the conductive performance is very poor, so it was broken by Tai Sui's foot, but it is not pig iron, and its texture is not as "scattered" as pig iron, and it is relatively more flexible.

The Thief simply leaned down and sniffed the smell emanating from the crack.

It was indeed the smell of iron after it had been heated, and there was a slight rusty smell.

Later, he carefully identified the color of the ground, and determined that it was a dark brown and black color.

"It's meteorite." The Thief came to a conclusion.

Tai Sui stared at the crack and said, "This meteorite layer is really thick enough. This crack must be more than two meters deep, and it hasn't even been torn through. ”

The thief took a moment to ponder, and then said to Tai Sui, "I have a conjecture. Perhaps, where we are now, is a huge meteorite. ”

Tai Sui didn't quite understand the meaning of these words: "What do you mean?" ”

"If you think about it this way, in an era earlier than ancient times, an extremely huge meteorite smashed through the surface of the earth and plunged deep into the earth's crust. The tunnel we are in was not built, but directly dug out of the meteorite. ”

Tai Sui thought about it, and this statement did not seem to be completely unfounded.

The appearance of Yunze Lake was originally like a crater filled with water, which may be the traces left by the meteorite when it fell.

Tai Sui patted the ground and said in a deep voice: "With the current technical strength, it is difficult to carve out such a huge tunnel in such a hard meteorite. ”

As he spoke, he raised his head again and looked at the bronze door that he had pierced.

You say that thing is a copper "door", which is a bit insulting to it.

Because the thickness of the door panel is beyond imagination.

The height of the whole door is only about 15 meters, but the thickness of the door panel is also a full 10 meters.

A door like this is absolutely impossible to open, not to mention that the door panel is too heavy, and it is impossible for ordinary people to push it open, even if it can be pushed open, there is not enough space for the door panel to open.

Such a huge metal creation, with the technological ability of this era, is difficult to build, not to mention that even if it can be built, no crane can transport such a heavy thing in.

The people who built this crypt had a technological power far beyond their time.

Tai Sui asked the thief saint: "What era did people build this underground palace?" ”

The thief saint immediately gave an answer, but there was also a bit of doubt in his tone: "It is said to be a creation of ancient times, and it has a history of more than 10,000 years. Let's put it this way, it appeared before the time when human beings recorded history in writing. ”

Perhaps 10,000 years ago, human civilization reached heights that are unattainable today.

Tai Sui thought of this, and the thief saint naturally thought of it too, otherwise his tone would not be so confused.

Tai Sui raised the lamp and walked to the breach that he had pierced, and tried to inhale the breath wafting from the other side of the hole, but found that the air on the other side of the bronze door was fresher.

In the air, there is a little smell of vegetation.

This is extremely abnormal, and it is impossible to grow vegetation in such a completely dark environment!

A great sense of uncertainty took root in Tai Sui's heart and quickly spread.

Now Tai Sui finally understands what the "evil nature" in the mouth of the thief saint means.

It's an extremely strong and strange aura, everything in front of you defends common sense, everything hides danger, such danger that you can't see them with the naked eye, but you can clearly feel their presence.

The thief first got into the doorway, and Tai Sui followed him with a lamp.

Let the thief take the lead is the most correct choice at the moment, in this weird environment, experience is far more important than combat effectiveness, this is like driving on a winding mountain road, the old driver in his fifties is more reliable than the young man who has just touched the car for a year or two, walking on the road next to the wheel is the cliff, but it is not to see far and hear far away to ensure safety, mainly by experience and mentality.

Behind the bronze gate, there is a deep tomb road.

The appearance of this tomb is very similar to the one under the office building, and the walls are also carved with upside-down tiger-footed beast-headed birds, and even the height of the ceiling and the width of the road surface are about the same.

The biggest difference is that the underground tunnel is basically made of stone, while this tomb is made of extremely thick meteoric iron, and under the wall of the tomb, there is a lantern every five meters.

The configuration of these ever-bright lamps is very special, all of them are all heavenly spirit pressure lamps, also called skull-breaking lamps.

It is in the form of a stone man kneeling on the ground, with a very serene expression on his face, his hands naturally behind his back, and his neck slightly stretched forward, as if he was expecting something.

The stone man's celestial spirit cover was chiseled into a fist-sized hole, and there was a wick and lamp oil in the cave.

The thief told Tai Sui that only the dead and evil spirits could see the light of this kind of everlasting lamp, and the living could never see it.

Because when the wick is lit, the expression of the stone man will become extremely hideous and gloomy, and once the living see their face, they will be haunted by nightmares for the rest of their lives, and they will never be able to be freed.

Most of the people who have seen this kind of light are crazy, and only a small number of people who have cultivated highly can keep their minds undisturbed, but they still can't escape the fate of being corrupted by nightmares for the rest of their lives.

Tai Sui couldn't help but be a little surprised: "You seem to know the things in this underground palace very well." ”

The thief shook his head sullenly: "My understanding of the underground palace is very limited, but this kind of everlasting lamp, I have seen it in the original world. Now I have a very strong feeling that the relationship between your world and the world I used to live in is really not ordinary. ”
