Everyone nodded again and again when they heard this, and Fang Ling couldn't help asking, "Brother He, since you know this central place, how can you open the passage?"

He Si deliberately fished his appetite and said: "The place of the void, although you can avoid the main gate and enter, but the builder will set up a big murder situation here to prevent someone from sneaking in from here, this center is the opening of the big murder situation, if it is destroyed at will, the whole room will also collapse, but ......" He took out a small hammer from the bag behind his back, this hammer was very dark as iron, it looked ordinary, he took the hammer and said:" This is our family's ancestral star-breaking hammer, which is made of mortal spiritual objects, as long as the direction is judged well, and the center can be smashed with this hammer, the stone hall can be prevented from collapsing. ”

Having said that, everyone was still taken aback, although they had long known that the underground palace was full of dangers and dense institutions, but they didn't expect to encounter a life and death crisis just after they came in.

Now the stone hall where everyone is located is ten zhang high from the ground, that is to say, the basalt above the head and the multicolored stone on the surface of the ground are ten zhang thick.

However, just when everyone was timid, He Si had already raised the star-breaking hammer and slammed it into the center, and everyone gasped in unison, and a heart hung in their throats.

Rao is Fang Ling and the three of them are very courageous, and they can't help but sweat secretly in this situation.

As soon as the hammer fell, the center shattered, and the stones around it suddenly loosened, and then they all fell downward, revealing a large hole, and looking down the hole, it was obvious to see a piece of land, and the stone above the head did not move at all, and there was no sign of stepping down.

Although everyone breathed a sigh of relief, they couldn't help but secretly curse He Si, engaging in this kind of sudden attack was simply to scare people to death, but at this time, He Si had already taken the lead in jumping down.

Fang Ling and the three of them jumped down one after another, and fell to the ground steadily, what appeared in front of everyone was a tortuous stone road, the dark green stone road extended straight forward, due to the reason that it had been buried underground for a long time, the stone wall was faintly green, and it didn't look real.

The whole space is filled with a faint water vapor, and there is shallow water on the ground that is not above the ankles, but fortunately, the stone road is quite wide, and there are no problems with five or six people side by side, and the top is also very high, five or six feet from the ground, and there is a multicolored stone on it, just from this point, it is certain that everyone has come to the first floor of the underground palace.

According to He Si's calculations, these seven-layer underground palaces are extremely large, so there is more than one passage to enter each lower layer, which also greatly reduces the probability of everyone meeting with the people of Tianji Hou and the Thirteen Princes, but for the sake of safety, everyone is cautious and tries not to make too much noise.

He Si walked in the front, Fang Ling and the three followed, and the Green Alliance followed behind.

It didn't take long to walk, and there were two forks in the road, one left and one right, both leading to a very far-reaching place, He Si pondered slightly, did not take a fork in the road, and continued to lead everyone forward.

However, the further you go, the more forks in the road there become, and almost every hundred steps you take, a fork in the road appears, and the stone path that everyone walks on is not in a straight line, but zigzag and curved.
