"System, survey!"

Zhang Nian used the survey to open the perspective of God, and slowly searched the situation around Yizhuang, Yizhuang is actually not small, and a radius of several kilometers belongs to the scope of Yizhuang.

As time passed, half an hour passed, and everything on the ground in Yizhuang was surveyed, but nothing unusual was found, let alone ghosts and zombies, not even a single bat.

"Is it underground?"

Zhang Nian muttered, his mind moved and continued to investigate underground, the survey on the ground is easy, almost does not consume any strength, but it is difficult underground.

The survey function of the system is also very slow underground, and it is difficult to advance even 10 meters at first, but after a while of surveying, it seems that the rock layer in the vicinity has been excavated, so the survey is labor-saving.

"It's strange, there don't seem to be large tombs near Yizhuang, why is the soil here so loose?"

Zhang Nian was puzzled and continued to investigate, but then he saw a shocking scene.

After passing through the thin layer of soil, it suddenly became clear that it was a tomb, surrounded by blue bricks, and there was no place to go out, which seemed to be a dead end.

"Three coffins? Or is it vertical? ”

Zhang Nian frowned, looking at the huge three coffins in front of him, each of which was as big as a copper-horned golden coffin, could it be that there were also three imperial relatives buried here?

It was a hundred meters in circumference, like a huge room, and not far from the coffin there were a number of cluttered wooden benches and wooden tables, although they had long since decayed, but all this indicated that this was a place where people lived or lived temporarily.

The most permeable thing is that there are two dark lamps next to each coffin, and the six dark lamps are like ghosts in the dark, and the turquoise flames emit a breathtaking light, as if they have been burning since a long time ago.

"Immortal Lamp?"

Zhang Nian muttered and released the survey function, but got a result of "unable to survey".

If Zhang Nian still believed that there was no way out here, but when he saw these dark lamps burning, Zhang Nian understood that there was definitely an exit here.

Zhang Nian comes from the modern civilized world, although he doesn't learn science very well, but at least he knows that oxygen can burn, so he concluded that there is definitely a way out here, but he has not been discovered by himself for the time being.

Just as Zhang Nian wanted to take a closer look at every detail, he suddenly heard a sound similar to wood breaking.

"Click! Click! ”

There was a cracking sound from one of the coffins, and Zhang Nian saw that the corpse qi seeping out of the cracks in the black coffin was much stronger than the ordinary ones, and Zhang Nian was sure that the zombies in these three coffins were definitely not simple.

I tried to investigate but failed, because there was an indecomposable corpse qi wrapped around, not to mention looking through the coffin, even if I wanted to get closer.

Although the survey function of the system is very convenient, to put it bluntly, it is not as strong as imagined, and not every place can be surveyed, which is the first one.

The principle of the survey is to decompose everything that Zhang Nian has seen in control, so that he can see things on the other side, but the energy contained in the three corpse qi wrapped in the coffin obviously exceeds Zhang Nian's current cultivation, so it can't be surveyed at all.

Although the three black coffins are placed here, with the flickering blue-green lights, it looks extremely penetrating, but Zhang Nian is not thinking about this, he is thinking about turning the zombies in these three coffins into his nourishment.

"I didn't expect that there are three coffins like this under Yizhuang, if the zombies inside come out, it will be a good show, and now this place is at least twenty meters from the ground.

According to current technology, it would take at least 100 people to build such a large tomb, and it would take several months to build such a large tomb.

It is impossible for such a large amount of manpower and material resources to be made by ordinary people, but the strange thing is that if these three coffins are some royal relatives, then why are there no funeral goods next to them?

You know, even if Zhang Nian's bronze horn gold coffin still has a large amount of gold and silver jewelry, let alone three coffins?

Zhang Nian thought about it, and felt that it was more appropriate to let the little green snake take a look, the little green snake seemed to have a natural resistance to corpse qi, otherwise it would have been corroded by corpse qi by its original cultivation.

A thought conveyed a command to Xiaoqing, and at the same time, Xiaoqing Snake began to slowly squirm, and finally slipped into the ground.

Don't look at the little green snake is not the size of a palm, but it is already a demon beast that has been practicing for 40 years, and it is easy for it to escape to the ground, and the speed is also extremely fast.

A few minutes later, the little green snake came in from the wall, and a large amount of air came in along the passage, but it didn't affect anything, how the green dark lamp should burn or how it burned, it seemed that it was not affected by this air at all.

"Zizi ......"

When the little green snake came in, he spat out a letter somewhere in the air, as if to say "I'm in" again
