there is a zombie in love with you

gravel.

The broken stones continued to fall, and even the stone bricks on the wall were shaken off.The echo reverberated in the cave, hitting again and again, and the large stone collapsed, causing the four people to flee with their heads in their arms, and had to flee under the eaves of the city gate they wanted to blow up.

"The strongest thing here is this door!" The ghost old man slapped the gravel and dust off his body and cursed.

Yu Chengjun was busy checking Jin's injuries.

Just now a falling rock the size of a fist hit Jin's head impartially. Although Jin held his head tearfully and screamed in pain, his head was probably harder than a stone. Even the stone was broken and his scalp was not scratched.

Although he had also imagined the possible risk of exploding the door, Yu Chengjun never expected that the amount of gunpowder used in the experiment could also cause such a huge chain reaction.As far as they could see, the already faded paintings on the rock walls were unable to withstand the force of the explosion and began to collapse. Large and small rocks rolled into the river, causing bursts of spray.

After the collapse came to an end, they came out of the shelter to check the situation.The explosion caused chaos everywhere, wall bricks and roof tiles fell to the ground one after another, and the murals that could still be seen in slight patterns were even more horrible.

Yu Chengjun thought, although the limestone caves are inherently fragile, but a small amount of gunpowder caused such a large-scale avalanche, the people who built this place must have tampered with the top of the rock.Stalactites are the best natural traps. As long as some cracks and grooves are chiseled at the roots, a slight vibration will cause a collapse.

Although a lot of rocks were shaken off, except for the glazed tiles that were blown to pieces, there was only a shallow hole in the roof.

Yu Chengjun carefully climbed up to look, and it turned out that what had just been blown up was only the outer layer of stone, and there was still a layer of iron plate inside.The gunpowder he brought should be enough to smash the gate or the roof, but the amount of gunpowder required for this thickness is too much, and exploding the door rashly may trigger the trap again.

"Gunpowder must never be used anymore. Now we can only find a way to open this door." The ghost old man said in a deep voice, "It will take several elephants to open this door. Let's split up and look around. There must be a key or something hidden nearby." What other way."

They separately studied the copper tripod and the painted paintings on the wall to find a solution. After several hours, they finally realized that it was futile. The door is smooth enough to almost serve as a mirror, where's the keyhole?

Ye Li kicked the copper tripod angrily, but there was no response except for a heavy impact sound and foot pain.

"Are we really going to be trapped in this place?" Ye Li asked dejectedly.

Yu Chengjun shook his head, "If we really can't open the door, we can blow up the iron fence below that blocks the waterway at the risk of collapse, but I don't know how long the bottom is, I'm afraid the scuba can't last that long. Another way , just waiting for Professor Luo to turn back here, but I think there should be another exit here, the part of the river we passed is basically a road that can only go out."

Jin Xing rushed up from below, his cheeks were slightly flushed and said: "There are fish in the water! If you really can't get out for the rest of your life, at least you won't starve to death..."

His discovery did not lift the spirits of the crowd.Yu Chengjun shook his head at Jin, advising him not to say such words that made people feel even more depressed when Ye Li and old man Gui were boiling with anger.

They lifted up almost every piece of brick and tile but still found nothing. Even Yu Chengjun, who had been searching silently, and Jin, who was by his side, felt tired after a long search.

The old ghost lit a fire beside him, ready for a long-term war of resistance, but the four of them sat around the fire relatively speechless.
