At the end of the water cave is this stone wall, which is a light water film to isolate the contact between the water and the wall, which can be regarded as a small invention in the era of science and technology.

The water film is extremely tough, it is specially used to block water, water molecules, can not stay on the water film, when the water comes into contact with the water film, the water will slide down, into the underground waterway.

Several people stood aside, looking at Lan Yang, and Lan Yang, who was pressing the elastic water film, seemed to be trying.

"Is there something behind this stone wall?" Looking at Lan Yang patting the wall, Sun Wei couldn't help but ask.

Lan Yang shook his head and said, "I don't know very well, but there should be something." ”

"In that case, we might as well smash it open!" Wang Yuting suggested on the side.

When Lan Yang heard this, he couldn't help but break out in a cold sweat, she was really a woman with violent tendencies! Everywhere I want to do sabotage.

Lan Yang said in a deep voice: "We have to figure out what is behind this. ”

"yes!" Sun Wei also broke out in a cold sweat: "Sister, why do you keep thinking about smashing things." ”

"Ahem......" Wang Yuting laughed dryly, looking a little embarrassed.

"Let me see ......" Lan Yang took out the 18th mobile phone, opened the three-dimensional map of Blue Sky City, locked the map on a house, and said: "This is where we are now, this is the water purification plant, we are below here." ”

"This waterway...... It's going east, right? Sun Wei looked at the three-dimensional map and hesitated slightly.

Lan Yang nodded, locked the map in this house, and turned the picture to the house, like a god's perspective, and turned the picture to the waterway.

"Yes, it is indeed to the east, and this is indeed the end of the waterway." Lan Yang looked at the stone wall on the map that was exactly the same as reality, and couldn't help but say.

"Behind this stone wall...... Lan Yang zoomed in on the screen again. It's a drainage compartment! ”

"Drain compartment?" When everyone heard this, their hearts were immediately settled.

The purpose of this drainage grid is to prevent the water overflow of the waterway and set up a water storage place, although the drainage grid is not large, but it leads to the various water pipes, and the excess water will flow into the water pipes.

"There should be a small door under this water." Lan Yang patted the stone wall and said.

"No, there's a row of wall holes at the water line, and we can't get through." Sun Wei jumped to the side of the waterway, pointed to a water line, and said.

"It seems that according to what Wang Yuting said, it is really going to break the ......wall," Lan Yang said shamefully.

When Wang Yuting heard this, she immediately became proud. patted the back of Sun Wei's head and said with a smile: "Brother, look, I still need this method!" How direct! ”

"Good...... Okay......" Sun Wei didn't know what to say, so he had to stand aside.

"Look at me." Wang Yuting clapped her fists, raised her hair, and tied up her horse, like a Sailor Moon who wanted to attack.

"Stop, sister, what are you going to do?" Sun Wei looked at Wang Yuting's appearance and asked strangely.

Wang Yuting was taken aback and said, "Break the stone wall!" ”

"Then you don't need to use your fists, the force is mutual, and you have to be injured if you break the wall!" Sun Wei said helplessly.

Wang Yuting said proudly: "It turns out that you are worried about me, don't worry, in this military region, no one has a higher physical toughness than me, and it is easy for me to break a stone wall and iron pillar!" ”

After that, Wang Yuting suddenly burst out, and the momentum of the pen wandering dragon flew across the air, and he made a sharp uppercut towards the stone wall!
