Chapter 1 What is this?

Yu Qingqiu frowned as he looked at the line of writing.

He naturally knew the allusion of "Cao Cao specially established the titles of Qiu Zhonglang General and Mōjin Xiaowei (grave robber), who plundered wherever they went, leaving no remains unexposed."

He had also arrested self-degrading cultivators who specialized in stealing graves and robbing burial objects.

He was well aware that throughout history, many kings and generals, worried about their tombs being robbed, had specially hired extraordinary people to build magnificent tombs with countless traps and mechanisms.

However, this tunnel still had fresh mucus, clearly recently excavated, so how could grave robbers have visited it?

"A deliberate attempt to mystify."

Yu Qingqiu snorted coldly, bent down, and carefully examined the ground.

He discovered that the middle path of the three forks seemed to have traces of soil being turned over and then smoothed over.

He stood up and tapped the side of the bamboo tube rhythmically with his fingers. The swarm of fireflies gathered at the top of the bamboo tube immediately split into two.

One half remained at the front of the bamboo tube,

While the other half detached from the bamboo tube, hovered in the air for a moment, and finally flew into the middle fork.

Yu Qingqiu didn't show any pride on his face. He held the bamboo tube in one hand and a long sword in the other, following the fireflies into the tunnel.

The tunnel was dark and winding, with occasional drops of water mixed with dirt falling.

The air wasn't as turbid as he had imagined. Listening carefully, he could even hear faint sounds of wind.

Twenty *zhang*, forty *zhang*...

Yu Qingqiu's toes skimmed the ground, moving as fast as a shooting star. His long robe fluttered fiercely.

He silently memorized the distance and angles of the tunnel he passed, slowly constructing a clear structural map of the tunnel in his mind.

He corresponded it with the surface, imagining which building in Luzhou he was under.

*Tap!*

The tunnel ahead suddenly ended. Yu Qingqiu stopped abruptly, avoiding crashing into the wall.

A large door blocked the way.

It was called a door, but it was actually a flat stone that completely blocked the tunnel.

The stone was generally grayish-white, cold to the touch, and extremely smooth.

There were no door handles or keyholes on it, only a crooked, narrow crack running through the stone surface, serving as a seam.

Below the crack, a line of crooked and ugly small characters was engraved:

"Mōjin Xiaowei (grave robber), together they live, divided they die. Three people are required to pass this door."

In front of the door, there was a stone floor connected to the stone wall.

Yu Qingqiu scanned up and down, not finding any mechanism.

He took half a step back, and the blade in his hand trembled crazily, emitting a very high-frequency hum.

A layer of light cyan *jian qi* (sword energy) was attached to the surface of the sword.

The small insects emitting orange-red light seemed to sense the danger and landed one after another, lying on the edge of the tunnel.

*Sizzle*—

The sharp blade easily penetrated the stone door, encountering no resistance, as if cutting tofu.

Just as Yu Qingqiu was about to cut a hole in the stone door to pass through, he heard a loud rumbling sound from behind the stone door.

The ground beneath his feet vibrated violently, and the tunnel above his head kept shaking off mud and sand, as if it was about to collapse.

The downward movement of the sword stopped, and the collapsing momentum of the tunnel also stopped abruptly.

This door...

Yu Qingqiu looked gloomy, staring at the stone door.

The other party seemed to have set some kind of restriction here.

If he damaged the stone door, the tunnel would immediately collapse, burying the intruder under tons of mud and sand.

Just like those ancient tombs.

He released the sword hilt and carefully examined the stone door again, still not finding any mechanism to open it.

"..."

After hesitating for a moment, Yu Qingqiu turned his palm into a knife and slashed at the soil on the edge of the stone door.

He tried to bypass the stone door and dig a small path to the back of the stone door.

It was good to have high martial arts skills. With the blessing of internal force, the efficiency of the palm knife was no less than that of an ordinary shovel, easily digging out a pile of dirt.

It was just that the underground was damp and the soil was dirty.

Before long, the white robe on Yu Qingqiu's body was so dirty that it was unrecognizable. He looked as black as if he had just climbed out of a coal mine.

One meter, two meters, three meters...

Yu Qingqiu dug mud all the way along the side of the stone door.

The expression on his face changed from calm and composed to somewhat hesitant, then to gloomy and uncertain, and finally to furious.

It's been ten meters! Why haven't I seen the edge yet? How wide is this stone?!

Yu Qingqiu took a deep breath, put down his slightly trembling right palm, and raised his left palm, stabbing it into the soil above the stone wall.

Sure enough... this stone was not only wide and thick,

It was also extremely high...

I just want to know, who would be so bored as to put a big stone here! Are they too idle?!

Yu Qingqiu angrily retracted his arm and resigned himself to returning to the front of the stone door. After a moment of pause, he silently turned around, walked back to the three-way intersection, and entered the left tunnel.

This road doesn't work, the other two roads should work, right?

Ten minutes later, Commander Yu, the Thousand Household, returned to the three-way intersection again, his hair disheveled, his body covered in mud, his body trembling slightly from excessive anger.

The remaining two... were also fake roads with the same stone doors standing there!

"Huff..."

Yu Qingqiu slowly exhaled a breath of turbid air, looked up at the sky, and let the underground water drip on his face.

Could it be that he would really be buried under these nine springs today?

"Mōjin Xiaowei (grave robber), together they live, divided they die, three people are needed, three people are needed..."

As if he had thought of something, he suddenly opened his eyes and ran quickly to the front of the stone door at the end of the middle fork. He stepped on the stone floor, circulated his internal force, and concentrated his *qi* (energy) in his *dantian* (energy center).

Making his body suddenly heavier, weighing as much as three adults.

This action seemed to trigger some kind of mechanism.

A dull and clear sound of mechanical structures operating came from behind the stone wall.

The indestructible stone wall split in half from the middle crack and slowly slid to both sides.

Revealing a darker tunnel with a more spacious and whistling wind sound.

"..."

There wasn't a trace of joy on Yu Qingqiu's face.

His premonition told him that, according to the nature of this mechanism, the road ahead would probably be even more difficult and dangerous.

Tap, tap, tap.

The sound of boots stepping on the muddy ground echoed in the tunnel.

In the orange-red light of the fireflies,

Yu Qingqiu once again arrived at the same three-way intersection.

This time, there was no writing about Mōjin Xiaowei (grave robber) above the three-way intersection. Instead, there were a few lines of small characters.

"There is a person whose surname is Tie (Iron), but he is born without hair. What disease does he have?

One: Seborrheic alopecia

Two: Seasonal alopecia

Three: Lao Tie (Old Iron) has no problem

Please choose the correct answer, enter the correct tunnel, and reach the next level."

The corner of Yu Qingqiu's eye twitched. He could understand every word on it, but when they were put together, it was like reading a heavenly book.

Then he could only use the, exhaustive method.

Commander Yu silently walked into the left tunnel and saw a stone wall standing at the end of the tunnel. In the middle of the stone wall, there was a protruding stone button with the words "Please Press" written on it.

Only a fool would press it.

Yu Qingqiu picked up a stone and threw it at the button from a distance of ten meters, hitting the target.
