In the darkness, there was only a lonely light from the flashlight of the mobile phone.

Du Xi suddenly said: "This is a ninety-ninety-nine stone steps, called the Rebirth Tongtian Steps, leading to the Imperial Tomb Underground Palace two hundred meters underground. ”

"Rebirth Tongtian Steps, such a large entrance, is it really to facilitate the resurrection of the First Emperor's army to return to the world?"

Nine hundred and ninety-nine stone steps, leading directly to the underground palace.

It was extremely dark here, and the light outside could not shine in at all, Yi Chen pulled Du Xi down slowly, counting his steps step by step, recording how many steps he had walked.

He walked for half an hour, and it wasn't until he counted to nine hundred and ninety that he saw a faint light coming from the underground palace.

"Here we are."

Du Xi said happily, and quickened her pace to go down, but she only took a few steps before she stopped.

"These... Is it the pearl of the night? All the pearls of the night? ”

This is a big outrageous road, about 30 meters high, 50 meters wide, and the length is unknown, because no matter whether you look to the left or right, you can't see the end.

I saw that the walls and ceilings of this corridor were all inlaid with luminous gems the size of a child's fist, which were extremely rounded.

These gems are like stars, I don't know how many they are, they exude a soft light, illuminating this wide corridor brighter than day.

"These aren't night pearls, they're fluorescent stones."

Yi Chen walked to the wall, stroked one of the glowing gems, and whispered.

Fluorescent stone, recorded in the Shennong Medical Scripture, is said to be a natural stone used for lighting in ancient times. Naturally it glows.

But in this era, none of them are gone. These stones. Even more precious than the real pearl of the night. As long as you take one out, it's a priceless treasure.

What he didn't expect was. Such a large underground palace is actually lit with this.

"First Emperor, what kind of person is he? Where did he get all this fluorescent stone? ”

Yi Chen had too much confusion in his heart.

"Brother Du, where should we go now?"

It's all made of hard stone slabs, but it's not like when you're on the mountain outside, it's full of fallen leaves, footprints and other traces, you can see it at a glance.

Here, Yi Chen couldn't see any traces left by Du Ze at all. But there are two roads in front of you, one to the left and the other to the right.

No matter which way you look, once you go in a different direction from the one Du Ze chose, it means that Du Ze may stay in this Mausoleum of the First Emperor forever.

The danger in the underground palace imperial tomb was secondary, and Yi Chen was worried about the martial artist who was following Du Ze.

"Du Ze!"

"Du Ze!"

“……”

Yi Chen suddenly opened his throat and shouted, he hoped that Du Ze had not gone far and could hear his voice and turn back.

But except for echoing in this underground palace. He couldn't hear any response outside of his echo.

"Let's go to the left and leave it to fate."

Yi Chen let out a long sigh and took Du Xi's hand. And he went to the left. In such a situation, he had no recourse.

"Brother Du, wait......"

Du Xi suddenly stopped. whispered. I saw her walk to the middle of the corridor and look ahead. Then he looked at the hard stone slabs of different sizes on the ground, which were used to pave the ground.

She closed her eyes suddenly. It's like thinking about something.

Yi Chen didn't bother her, and also observed the stone slabs on the ground, only to see that although these stone slabs were of different sizes and shapes, they seemed to be irregular.

But in fact, it seems to contain some kind of law.

Du Xi carefully recalled the topographic map of the Mausoleum of the First Emperor that she had seen several times. He compared the stone slabs on the ground again, carefully compared them in his mind several times, and then whispered: "Brother Du, let's go." When I walk ahead, you follow me, and your footsteps must be walking on the same stone slabs as mine. ”

"Hmm."

Yi Chen nodded, he also knew the urgency of the situation, in this kind of imperial tomb, if there was no mechanism, Yi Chen himself didn't believe it.

"Go forward for a while, there should be a door, go in to the periphery of the imperial mausoleum, the periphery is quite safe, let's go in and look for it, if we can't see Du Ze." Brother Du, you can go back by yourself. The core area of the Imperial Tomb is too dangerous, and even I don't know where the terrain and mechanisms are buried in the core of the Imperial Tomb, and I can't let you take risks just to find Du Ze. ”

Du Xi said in a low voice and walked forward.

The entire underground palace was quiet and terrifying, even if a needle fell to the ground, I am afraid it could be heard, Yi Chen's heart was always uneasy, he always felt that this place was not the place he should be.

"Ahh

At this moment, Du Xi in front of him suddenly let out an exclamation, only to see a sharp arrow flying quickly from the wall on the side.

"Hide!"

In a hurry, Yi Chen roared and quickly pushed Du Xi to the side, but he was shot in his arm by a sharp arrow and stuck in his arm. The blood was also stained black with rust on the arrows.

"Ahh Brother Du, are you alright? ”

"Don't talk."

Yi Chen shouted in a deep voice, he had a strong sense of crisis in his heart at this time, and it was close at hand.

Click......

Yi Chen's sensitive ears heard the sound of clattering machines coming from the walls around him.

"Get out of here!"

Saying that, Yi Chen didn't wait for Du Xi to react, and hurriedly pulled Du Xi with his uninjured other hand, and quickly retreated from the entrance.

Whoosh whoosh ......

I saw that at this moment, countless sharp arrows flew out of the walls on both sides, and they actually shot the opposite wall into a thousand holes.

Then, with a clattering sound, a wall rose behind the arrows, blocking the way in.

"Ahh

Du Xi's mouth opened wide, and he looked at the wall in front of him with incredulity, if they took a step back too late, they would definitely be shot into a sieve, and there would be death or life.

And this is the outermost part of the Mausoleum of the First Emperor. I've just entered the entrance.

"Brother Du, are you okay? Your hands ......"

I saw that Yi Chen's arm was still bleeding, and the blood mixed with the rust on the arrow turned black.

Du Xi held back tears. said anxiously: "Brother Du, your injuries need to be dealt with immediately." Otherwise the rust will make the wound infected. It's all my fault, if it weren't for saving me, you wouldn't have been hurt. Why don't you go back first...... I went to Du Ze alone. As soon as I found him, I called him back. ”

Her eyes were full of tears, if it weren't for Yi Chen just now, she would definitely be shot cold, and she couldn't die anymore.

Yi Chen shook his head slightly, and he took out a silver needle. Hurriedly stabbed on the acupuncture points on his arm, and first stopped the bleeding.

Only then did he run Shennong's essence to the wound, first broke the tail of the arrow, gritted his teeth, and pulled out the arrow directly.

Enduring the severe pain, Yi Chen tore off the sleeves of his clothes again, and briefly treated the wound before asking, "What happened just now." Haven't you seen the topographical map of the mechanism here? Why did you trigger the trap? ”

"I... I ......"

Du Xi was speechless.

"Ugh..."

Yi Chen shook his head slightly, although Du Xi had seen the distribution map of the organs here, it was obvious that she had not been here either. And because she was worried about Du Ze's safety just now, she was obviously distracted.

Yi Chen said in a low voice: "Time is urgent, don't think about what happened just now." Now the road on the left is blocked. Let's go to the right. Maybe this is providence, maybe the right is the road that Du Ze has walked? But. Don't necessarily remember this time and don't get distracted again. ”

"Hmm."

Du Xi nodded lightly. She pondered for a moment again, putting aside all the other emotions in her mind before she stepped forward.

This time, the two of them were obviously much luckier, and they walked for about ten minutes without any accidents.

It's just that the road ahead seems to have no end, and this wide road still can't be seen.

Yi Chen asked in a low voice, "What's the matter, how far is this road?" ”

"This is also a formation, the road is not ahead, if you keep moving forward, even if you go to the end of your life, you will not be able to reach the end of this road."

"This is it."

Du Xi said softly, she suddenly stopped, stopped by the wall, searching for something on the wall, her hand kept pressing on the wall.

Thundered......

Yi Chen suddenly heard a deafening roar, and he felt that the entire underground palace was trembling.

"Du Xi, let's go!"

"It's okay, Brother Du, this is the sound from the door opening."

As if to confirm Du Xi's words, as soon as her words fell, a crack opened in the wall in front of her.

The roar continued until a five-meter-wide entrance was opened.

"If you enter from here, you can really enter the Imperial Tomb Underground Palace." Du Xi said in a low voice, and walked inside first.

Before entering the inside, Yi Chen felt a monstrous heat wave coming.

"Footprints, Brother Du, there are footprints here, Du Ze really entered from here, great."

Du Xi said excitedly.

It's not like the previous road, there are stones on the ground and walls, and the walls here are not stones, but tamped earth.

After thousands of years, a layer of ash fell on the ground, and Yi Chen looked down and saw that there were indeed many clear footprints.

"These are Du Ze's footprints, let's speed up and catch up with them quickly."

Yi Chen said, but he didn't take two steps before he was stunned, he finally knew what this heat wave was.

Not far ahead, there was a river of magma up to 100 meters wide, blocking the way forward.

In the magma river, like boiling water, from time to time there is a large canopy of flames, and you can imagine what will happen to people once they fall into this river.

Turning her head to look, she saw that Du Xi was looking for something on the wall again, she smiled and said, "Brother Du, you wait a while, when I find the way to open the mechanism, we can go over." (To be continued......)
