It's late at night, and you can still hear the noise of the bustling streets, where the manhole cover is located, a dark cul-de-sac.

Everyone looked around, there was no one around, Jin Buchang quickly opened the manhole cover and jumped down, and quickly closed the manhole cover on the top of his head, used his hands and feet together, and stepped on the nail on the cave wall to the bottom of the cave.

The bottom of the cave is very large, the ground is full of sewage, and a large group of mutant rats see someone and run around frantically, and the wolf brings the equipment in the bag to everyone.

Tight-fitting waterproof coveralls, miner's lamp caps, portable reagents, and compression oxygen bags.

Everyone quickly got dressed and put on their equipment, and the wolf took the lead in front of them, turning around for more than ten minutes, and finally turned into a branch passage.

"This is the entrance to the underground labyrinth." The wolf pointed to a large stack of ropes tied together next to him, leading to the depths of the underground labyrinth.

Obviously, these ropes were left by the three Qingyu brothers.

Jin Buchang also served the three Qingyu brothers in his heart, and he could find such a secret place, if it wasn't for the ghost wolf to lead the way today, he would definitely not be able to get around.

"The three Qingyu brothers used this stupid method to explore the way in the underground labyrinth?"

"It can only show that their luck is really good, they have explored a small part of the underground labyrinth, and they have avoided all the traps, and I don't know where they got this news." The wolf nodded, and led the way into the underground labyrinth.

Wen Ya found that the wolf did not go in the direction of the rope completely, and after turning more than a dozen turns in the underground maze, the wolf led everyone to a dead end, put down the package on his back, and took out a set of equipment from it.

A folding sapper shovel, a micro drill rig, a battery.

Black Wolf quickly helped install the rig and battery, and Wolf quickly determined the location on the wall.

"This is it." The wolf pointed to the left side of the wall, and the black wolf picked up the miniature turnaround and pressed the drill bit tightly against the wall, and soon the sharp drill bit cut a large piece of the wall.

Then, the wolf took out two blades from the bag and installed them on the drill bit, the sharp blades were driven by the battery, and soon drilled through the wall, and the wolf shoveled the surrounding soil with a sapper shovel, and soon a big hole appeared in front of everyone.

The wolf tested the ventilation of the cave with his hands, "Rest for ten minutes, and then go in." ”

"What's going on? Why take a 10-minute break? Jin Buchang asked.

"The underground maze is not the maze we are common, it is a composite hidden type, there is a set in the set, there is a game in the game, if you follow the stupid method of the three brothers of Qingyu, it would be good to be able to go through the outermost layer of the maze."

Compound hidden maze?

Everyone was dumbfounded, sure enough, there is a specialization in the art industry, who would have thought that the maze could be designed as a superimposed maze layer upon layer.

And the drilling rig used by the magic wolf is also very special, not only can it easily drill holes in the cave wall, but the best thing is that there is almost no noise in the drilling rig work.

"The 10-minute rest is to ventilate the maze, and the superimposed maze is a relatively closed environment, and the ventilation is to allow fresh air to circulate."

More than half an hour passed unconsciously, and from the beginning of entering the second layer of the labyrinth, the speed of the wolf's behavior slowed down significantly, and everyone silently followed behind the wolf without making a sound, keeping a quiet environment that was convenient for the wolf's reasoning and calculation.
