"Maybe we've been buried in a river of magma beneath the fault!" the young voice was full of schadenfreude.

"You are right, but you really ran for nothing. Let's go back to hibernation. The old voice restarted the scanning mode, and no other intruders were found.

Little could she have imagined that a daring creature was hiding behind the door behind them, dodging the disaster......

Lan Xin hid behind the door and waited for a long time, listening to the heavy mech leaders walking farther and farther away until they disappeared completely.

After a long time, only the sound of the wind under the fault and the rushing of the lava river can be heard.

Lan Xin didn't dare to come out directly, after all, the opponent was too strong, she didn't dare to hit the stone with an egg at all, she was afraid that she would be hacked to death by the mecha leaders as soon as she went out.

She waited a long time in trepidation, before she carefully threw a stone, and then listened nervously.

Hearing the crisp sound of stones falling to the ground, there was no danger, and Lan Xin waited for a while before tentatively stretching out a foot.

She crept out from behind the door, only to notice that nothing had changed outside.

She peeked into the door again, and was so startled that she almost weakened her legs.

I saw that in the empty hall in the door, there were seven or eight tall mecha leaders standing upright in the corner.

Although it doesn't seem to be as advanced as the mecha that leads the team, it's still not something that a little ant can compete with.

The only good thing is that the mechs seem to be dormant, the mechanical eyes are dark, and it seems that her existence is not noticed.

Lan Xin quickly hid behind the door again, she forced herself to calm down, and began to think about how to deal with the current predicament.

The previous mecha leaders also said that the tomb guard mecha sent out had been scrapped, but it was clear that some tomb guard mecha had only been damaged, and they hadn't had time to mend the knife yet.

Could it be that Shi Bao or Nalan Yu did it?

Or are those tomb guarding mecha themselves limited in energy, and once they are damaged and can't return to the dungeon in time, they will be automatically scrapped?

Lan Xin became more and more sure that it was the latter, after all, although Shi Bao was brave, he would never risk his life to make up for it. And whether Nalan Yu can get out of the mural corridor is still a problem!

Lan Xin thought, it can be seen that the energy of these tomb guarding mecha is also limited, after all, the energy required by the mecha is also very large.

The mecha who served as the tomb guard were a product of the romance era of the mecha master, and the mecha technology at that time was not necessarily more advanced than it is now.

Lan Xin thought like this, and accidentally saw the obsidian block on the ground, and she suddenly came up with a brilliant idea.

Lan Xin also understood that the sound of the mecha moving was too heavy, and once he went out, he would definitely alarm these mecha leaders, and then he would definitely die.

I saw that Lan Xin lifted the mecha state and set it to a hidden state. In fact, the mecha quickly turned into a stone ball, so it was not noticeable.

Feeling the thin oxygen in the air, she had no choice but to hurriedly run the Heavenly Fragrance Secret Technique. Her physiology is deeply affected by the secret art of Tianxiang, as long as she silently recites those flower words that she knows by heart, she will return to that kind of flower body.

Feeling the meager oxygen provided by the cherry blossom petals, she lightly picked up an obsidian block on the ground.

Then he boldly walked into the dungeon, and before he had time to observe the layout of the dungeon, he hurriedly came to the first tall mecha leader.

Lan Xin made a hole in the soft stone, and saw the black liquid in the stone flowing out.

She had planned to bring in the torches, which would have paid off more quickly, but she had considered that it would be too bad if the temperature of the torches alarmed the mech leaders.

Lan Xin took an obsidian stone in one hand and came in without hesitation. She walked over to the mech leader and lightly smeared the black liquid on the wall behind her.

Since the mech leaders happened to be dormant against the wall, Lan Xin came up with the idea. Although the black liquid would solidify a little slower without the temperature of the torch, she didn't dare to take that risk to use the torch at the moment.

Ever since Lan Xin used the black liquid in this obsidian to repair her mecha, she also deeply felt that the strength of this obsidian liquid shell was harder and more durable than her own mecha shell.

Lan Xin is also a mecha warrior herself, and she also understands that a mecha in a dormant state will basically not wake up as long as it is not a loud sound.

She was relieved to sneak in, and she smeared enough obsidian liquid on the part next to the mech leader and the wall.

He even boldly applied some to the big mechanical eyes of the mech leaders, anyway, these black liquids don't seem to fade, hehe......

Blue Heart's small figure was running around the mecha leaders, busy and happy.

Anyway, there was a lot of black liquid in these two obsidian stones, and she had already painted the eight tall mech leaders and the places next to the walls with black liquid.

In particular, the position of the feet and hands is applied the most. Even the first painted mech leader has been firmly glued to the wall.

After taking a closer look at the iron wall, Lan Xin nodded with satisfaction, and she was also glad that there were no accidents in the middle.

After doing all this, Lan Xin felt that the oxygen provided by her flower body made her in good physical condition, so that she would not have to breathe like everyone else.

She also had time to start looking at the dungeon. I saw that in this large space, there was a mecha leader guarding every direction.

As for the top of the head, there are even some small fluorescent stones embedded in them, which emit a dim light, but people can barely see the scene here.

She thought there was some skylight or something, so it was so bright. It turned out to be a small stone that glowed, which was a good idea.

Lan Xin saw that in the middle of the dungeon was a bronze lid, and it seemed that there was some unknown secret passage underneath.

There are a few big characters written vertically on the wall of the dungeon, but unfortunately I am now in the state of Tianxiang Flower Body, and I can't read, but I read the text and feel a little dizzy.

Lan Xin originally wanted to go back and merge with the mecha and come in again to continue exploring the exit, but he was afraid that the black liquid would not be enough to imprison the eight tall mecha leaders.

She finally decided to continue like this, and she tried to lift the bronze lid, only to find that it seemed to have merged with the ground, and was not moving.

Lan Xin thought about it, and then lay on the ground to observe carefully. If you can open this lid, will there be a tunnel underneath that leads to the mural corridor outside?

Then she waited a little longer, until the black liquid was completely solidified, and went out to wear her mech.

Go out from the tunnel again, locate through the mecha, find Shi Bao and Nalan Yu, and drag the tomb guard mecha back, it will be in vain.

However, after lying on the ground for most of the day, there was no way to open the bronze lid......
