For a while, hidden weapons flew in the yard, like rain.

Ding Cheng pulled Yun Ying behind him, took off his robe, danced in a ball, and knocked the hidden weapons to the ground one after another. Lingxuzi and Xuanzhen Daoren also danced long swords in their hands, fighting and retreating.

Several people retreated into the room and quickly closed the door. Suddenly, there was a click on the roof, a large hole was broken, and then a handful of iron sand was knocked down.

Ding Cheng's eyes were quick, and he pulled a table next to him to protect him. Lingxuzi had already hid by the wall, kicked through the wall panel, and got into the bedroom next to him, holding a quilt on top of his head.

But Xuan Zhen couldn't dodge, and a few grains of iron sand hit him in the face. Originally, he was hit by a few grains of iron sand, but he was only slightly injured. But this iron sand is highly toxic. Xuan Zhen suddenly threw away the long sword in his hand, grabbed his face with both hands, and scratched a face in a few strokes.

Immediately after that, Xuan Zhen was like crazy, crying hysterically, and at the same time his hands were dancing and grabbing, beating the tables, chairs and benches in the room to pieces. Even the surrounding walls and pillars were shattered. These houses are all wooden structures, and they are old, where can they withstand such a toss. The roof tiles were whizzing and falling, and the room was about to collapse.

When this room collapsed, the people in the house had to be injured. But if you rush out of the house at this time, the hidden weapons made by the white-clothed people outside will be unavoidable.

Cloud Shadow froze, looked around, and suddenly found a corner of the floor in the corner of the house under the strong impact. Cloud Shadow rushed a piece of wood above his head to the corner of the house, and lifted the floor with all his might, revealing a large hole.

Yunying called Ding Cheng, and Ding Cheng also turned around and saw the big hole. Just then, one wall could not withstand the impact and fell, and the entire roof collapsed downward. Ding Cheng lunged forward and grabbed Xuan Zhen's collar and dragged him towards the entrance of the cave.

At the moment when the whole house collapsed, the three of them happened to burrow into the hole. Ding Cheng took a look through the faint light and saw that Xuan Zhen's face was no longer humanoid, the muscles on his face were stiff, his eyes were wide open, and he was motionless. Ding Cheng touched the artery in Xuanzhen's neck and found that there was no pulse.

Ding Cheng untied the box on Xuan Zhen's back, pulled the box and Yunying and walked to the depths of the tunnel.

The two walked forward for a short time and found that the underground tunnels of this large courtyard extend in all directions, and the design is exquisite, and the lighting and air permeability are very good.

Ding Cheng and Yun Ying rested for a while at the entrance of an intersection cave, and then randomly chose a tunnel and walked forward.

The two walked in the tunnels for a while, and found that none of the tunnels were exactly the same, and they couldn't tell the southeast and northwest at all, and they didn't know where they went.

Suddenly, Yun Ying found that they had returned to the place where they had rested just now, and the traces of the two of them sitting on the ground were still there, especially the indentation of the box on the ground was clearly visible.

Ding Cheng scratched his head and said, "It seems that we are lost." ”

Yunying said: "We might as well go along a straight line, no matter how long the tunnel is, we can get out." ”

Ding Cheng said: "Yes, if we go in a straight line, we won't go around again, just in case, we will make marks along the way." With that, Ding Cheng reached out and grabbed a small stone in the corner of the wall, and carved a notch on the wall on the right hand.

The two of them kept walking forward, marking the wall as they went.
