Starshadow said, "Although the Emperor's Tomb has not been excavated, it has been closely protected. If someone digs a tunnel underneath, the staff of the Cultural Heritage Bureau will notice it. And now this tunnel doesn't look like it was dug up in the last few years, and it looks like these facilities must be decades old. ”

Yin Bing said: "Then it means that this tunnel was not dug for the Emperor's Mausoleum, it belongs to the Little White Building, so where will it lead?

Starshadow smiled, "Instead of asking so many whys, let's speed up a little bit, and we'll see." ”

Yin Bing immediately quickened his pace when he heard this, and the headlamps on the heads of the two of them were specially made by Tongcheng, waterproof and fog-proof, and the power was long-lasting. This tunnel is not a big place, and there is no writing or pattern on the surrounding earthen walls, let alone a fork in the road, they just need to walk all the way.

The two of them walked for nearly an hour, and gradually Yin Bing felt the upward trend of the road, and the two walked for more than twenty minutes, and they actually came to the end, and a small circular door appeared in front of them. Yin Bing took a little effort to open the rusty door and found that there was a sewer pipe outside.

Holding back the smell of smoky **, Yin Bing and Xingying came out of the sewer, and the two of them were actually standing in a not prosperous neighborhood at this time, and after positioning, it seemed that they had actually come from the east of the ancient city to somewhere in the south.

At this time, it was still early in the morning, there was almost no one on the road, Yin Bing and Xingying were sitting on the side of the road, the two of them were puzzled, this was an ordinary tunnel, it seemed that it had almost no other function except for escape, but why did the Eastern Underworld Sect guard this place and refuse to leave? Could it be that their secret was not in this tunnel, but somewhere else in the small white building?

Yin Bing asked Xingying: "Xingying, should we go back the same way or take a taxi back?"

Starshadow thought for a moment and said, "Let's go back the way we came, I think we should have missed something!"

Yin Bing sighed, obviously he didn't want to go down that tunnel again, "Okay, sacrifice your life to accompany the gentleman!"

The two of them returned to the tunnel again, this time Starshadow did not hurry away, she first observed the iron gate that connected the tunnel to the sewer.

"Yin Bing, have you noticed that this iron door has been very rusty, and it seems that no one has touched it for a long time. ”

"Well, it took a lot of effort for me to push it open! Eh, wait, you mean that the people of the Eastern Underworld Sect didn't walk through this door, and if they found this tunnel and were using it to do something, they didn't make it to this end, did they?"

Xingying nodded, and after Yin Bing understood Xingying's train of thought, he followed the train of thought, and he squatted down to observe the ground carefully.

"There are very few footprints here, except for the one we just stepped on, and a few more footprints that seem to be months old. ”

The two walked back along the path they had come from, observing the footprints on the ground as they went, and this time their speed slowed down a lot. They walked back nearly half the distance, and suddenly Yin Bing noticed that there were more footprints on the ground. To be exact, the degree of wear and tear of the ground has changed, and the ground is flat and smooth, and it is clear that people have often walked in this place.

Following the clues given by the ground, Yin Bing and Xingying moved their gaze to the small hole at the edge of the passage that could only accommodate one person.

"Hey, interesting, how do these footprints lead to this little hole, what's here?"

With that, Yin Bing took the lead in entering the small hole, which looked no different from the others at first glance, except that there were no items such as food and water.

Yin Bing carefully observed the small hole, but the star shadow behind him squeezed over, pointed to a place and said, there is a mechanism here. Yin Bing saw that the place where Xingying was talking about had a very subtle handprint, which was almost impossible to see in this hole without light.

Yin Bing didn't realize what kind of mechanism this was, he reached out and wanted to touch it. Xingying said directly: "This is a fingerprint scanner. ”

Yin Bing leaned his face over and looked at it carefully for a long time, "Wow, Xingying, how did you see it, do your eyes see through X-rays?"

Xingying stood behind Yin Bing's face and changed slightly, and then a men's voice in a cheap tone came out: "Let me go!

The spirit pupil condensed around Yin Bing, and squeezed Yin Bing out of the cave, Yin Bing asked in surprise: "Hey, aren't you an image, how can you still push me?"

Yin Bing touched the spirit pupil as he spoke, and found that the spirit pupil was actually a physical one, that is, the robot spirit pupil that appeared next to Yin Bing now.

"Old Spirit, you, how did you get here?"

"Molecular Teleporter, as long as someone here locates me, I can teleport over, and I'm not alive. ”

Yin Bing turned to Xingying again, "Xingying, your positioning for him?"

Starshadow nodded.

Yin Bing opened his mouth in surprise, "Old Ling, then you robots are against the sky, aren't you really teleporting and flashing?"

Lingtong looked proud, but said modestly: "Where! Where! It's not like you think, we can go wherever we want, someone must first leave the positioning coordinates at the teleportation point before we can pass over." ”

Yin Bing said: "Niu Xuan, your skill is more powerful than the Pioneer Warrior! Come on, unlock a fingerprint scanner, and you will complete the task." I really didn't expect a fingerprint scanner to pop up in this tunnel, I thought it would be an ancient mechanism!"

Lingtong had already put his hand on the corner of the scanner, cracking the code, and he also had the energy to chat with Yin Bing here, "Pay attention to the tone of your voice, I am the one who assigned you the task, and I am definitely the leader." It's your pleasure that I'm here to help you, if the other Forerunners let them crack this low-level machine on their own. ”

"Shouldn't I gratefully kowtow to you?"

"No, no, I didn't prepare a red envelope! Okay, untie it. ”

With the words of the spirit pupil, the earthen wall in front of them actually opened from the side, and there was another passage inside.

Yin Bing looked back at the outside of the passage, there was a small hole like this every fifty meters or so, if there were passages, this would be an underground channel network.

Xingying seemed to guess what Yin Bing was thinking, she said: "There won't be many such forks, you look at the soil in this passage, obviously this is newly dug recently, looking at the number of members of the Eastern Netherworld Sect who were stationed here before, it would be good if they could dig one out in a year." ”

Yin Bing nodded, and seeing that the spirit pupil was already in front, he immediately let Xingying walk in the middle, and he came to the back. With Lingtong's kind of tunnel, it became very easy, and Lingtong called up the structure map of the city in front of him, and their current direction was indeed in the direction of the emperor's mausoleum.

After going a long way, the passage also came to an end, and at the end of the road was a huge machine.

Yin Bing looked at this machine that he didn't know what to do and said with emotion: "How did such a big machine come in through this narrow passage?"

Lingtong's eyes lit up and said, "I see!"
