Sunny autumn night, starry. In the cold wind, a shrunken figure walked step by step towards the gap in the fence on the east side of the playground of Xijing Jianzhu University.

Li Shilan herself didn't know why, in the middle of such a windy autumn night, where did she get the courage to explore this mysterious Tang Dynasty underground palace alone.

Is curiosity at work? Or guided by a meteor that has just streaked across the night sky? Or is it bewitched by some mysterious power? In confusion, Li Shilan had come to the gap in the wall.

"It's dangerous here, idlers stop!" Eight large characters on the iron sign standing in front of the gap in the fence are faintly visible.

The archaeological work does not seem to have gone very well, and the wall on the east side of the campus has been demolished for nearly a week, but the excavated pit is still outside the wall and has not been extended. Because of this, the dim and dim light in the pit is almost invisible on the playground.

Li Shilan gently pulled open the fence and stepped out of the fence.

What catches your eye is a large pit of black pressing. Through the faint light in the pit, Li Shilan carefully observed the situation below. The whole feels like a World War II trench, but it's much deeper than the trenches. The staggered arrangement of the tunnels looks like a labyrinth, but it is not as regular as a labyrinth.

Li Shilan raised her head and looked around, as if no one was on duty. "No matter, let's go down and see." I thought to myself.

The pit near the gap in the wall is not too deep, and there is a slope, for Li Shilan, who is 1.82 meters, it is not difficult to go down, as for how to get up, it seems that he is not concerned at the moment.

"Ahh

Li Shilan, who had a firm foothold, patted the dust on her body, raised her eyes and scanned the situation in the tunnel from left to right. There are three roads to walk in front of you, the left, the middle and the right, the middle of the tunnel is not long, and you can see the head less than five meters ahead.

"Left or right?" Li Shilan thought in her heart, "Let's go to the left first." He quickly made up his mind.

Slowly groping, walked out more than ten meters to the left, the tunnel turned right, and another row of wooden fences crossed in front of him: "Be careful and slow down!" Li Shilan walked around from the right side of the fence. Within a few meters, a stone path that stretched downward under the lights appeared, and the road was more than two meters wide. The few lights swayed in the autumn wind, making it impossible to see how deep the road really was.

Li Shilan held on to the pit wall on the right and slowly walked down the stone steps. With each step down, it seemed that the light became more dim. Li Shilan's heart was beating faster and faster, and the sweat on her hands wet the soil on the pit wall and became slimy. After about fifty or sixty steps, I finally reached a flat land. "So deep!" Li Shilan, who was standing on the flat ground, let out a sigh and sighed.

The floor of this flat land is also paved with stones. The reason why Li Shilan can judge the material of the ground is all based on the feeling of feet, because there is almost no light here. After walking forward for another five or six meters, I almost hit my head, and it seemed like a dead end in front of me! No, it's a door! His eyes, which had gradually adapted to the dark environment, helped him make out the outline. And the middle seam and door knocker that he touched with both hands convinced him that he was right!

"The gate of the dungeon!" Li Shilan was secretly excited.

After carefully looking up and down, left and right, Li Shilan saw the stone gate in front of her more clearly. The stone gate is more than two metres high and about one and a half metres wide. The left and right doors are symmetrically inlaid with two metal knockers. Looking up, there was a beast head on the door, which should be a lion unicorn or something, and the light was too dim to distinguish it. The door frame is carved with a pattern, which of course is also touched.

"Can't get in?" Li Shilan's mind was a little messy.

"If you come here, you will be safe! There is not necessarily a second time in a lifetime. Enter! "I secretly cheered myself up in my heart.

Li Shilan held down the stone gate with both hands, lungeed with her legs, and her feet were down-to-earth, and the dantian took a breath of relief, "Open ...... Open...... Open! "I pushed it three times in a row, but the stone door didn't move!

"What's going on?" Li Shilan, whose face was flushed, rubbed her aching wrist.

"Could it be...... Is this door open outward? Li Shilan pondered.

"If you don't do it, try it!" Grabbing a knocker in each hand, he still made his lunge and was full of luck. I silently recited one, two, three, and shouted: "Open!" ”

"Squeak......" The knocker moved, and the door—still didn't move.

"Oops, fight me! Isn't it? Li Shilan was unwilling and wanted to try again.

"Who? Who's there? A man's voice was heard not far away.

Li Shilan was startled and quickly shrank into the corner between the stone gate and the pit wall.

"Hey, don't run!" The man shouted, "Hey, what about you, stop ......"

Li Shilan didn't dare to move, and even held her breath. At the same time, it was also realized that the man, who might have been a night watchman at the archaeological site, did not notice himself.

The shouting continued, but it seemed to be getting farther and farther away. "Whew-" Li Shilan let out a long breath.

"Before going down to the pit just now, I obviously didn't see a vigil." Li Shilan thought, "The stone gate can't be opened, and a night watchman will be killed halfway, and there may be a tomb robber or something running." Hey, that's bad luck! Today's expedition seems to have ended here, and I don't know if I can get out of it all. Trespassing on the archaeological site is not a big deal, but it will be troublesome if the school imposes a sanction. ”

After waiting for another ten minutes or so, there didn't seem to be any movement outside, and Li Shilan stepped on the steps lightly. The stone steps up the stone stairs seemed to be longer than when they came down, and they had to be careful and have to prick up their ears.

Finally climbing the last step of the staircase, Li Shilan bypassed the wooden fence from the left, leaned against the pit wall, and looked to the left. It's okay not to look at it, but after reading it, Li Shilan's heart almost didn't mention her throat. The night watchman, I don't know when, got a chair and placed it between the gap in the school wall and the tunnel, that is, where Li Shilan slipped down, and sat on it and smoked.

"I'm going to go! This is not for me to go back! Li Shilan cursed. What to do? I don't want to spend the night here! ”

"Hmm...... Wait a little longer, and I won't believe he doesn't sleep. "I raised my hand and looked at the luminous watch, and the hands showed that it was exactly half past twelve!

A cold wind blew, and Li Shilan shivered and woke up. In a daze, look up at the watch: one hour forty!

"When did I fall asleep?" Li Shilan snorted while thinking about it, and at the same time felt a little pain in her head, "Hey, I'm cold, unlucky!" ”

"I have to hurry back to the dormitory, otherwise I will go directly to the hospital at dawn to get the hanging bottle." Li Shilan poked her head out again while thinking.

The folding chairs were still on the edge of the pit, but there was no one on them. Li Shilan was secretly happy in her heart: "Sure enough, he can't stand it anymore!" ”

Slowly getting up, slowly moving her steps against the side wall of the tunnel, Li Shilan came to the place where she came down.

I didn't think it was when I slid down just now, but now when I look up, this pit is still quite deep. Although there is a slope, it is estimated that it will not be able to go up.

"It would be nice to use the vacation after the college entrance examination to learn parkour!" Li Shilan thought wildly.

Looking up and down the pit wall repeatedly, Li Shilan's eyes suddenly lit up: "Chair!" I can run up the pit ramp, I can't go up, but I can reach the folding chair, and then I can put the chair at the bottom of the pit and maybe step on it and go up. Li Shilan was complacent about her "ingenuity".

"Yes, this pit in the middle of the road is right opposite the slope of the pit under the chair. You can use this distance of five or six meters to run. Li Shilan is more confident in the implementation of her own idea!

Facing the direction of the chair and the ramp, slowly reversing to defend against the sudden appearance of the Night Man. After eight or nine steps back, it is estimated that I am almost at the top of the middle road tunnel. He touched it back, trying to make sure it was already a pit wall.

Li Shilan did touch something, but that touch was not dirt, but fabric! "Ah......h
