Walking down the air door, you will feel brighter and brighter, and the sharpness in the same roadway is also bigger and bigger. This is an air outlet, and the wind direction of the roadway is ejected from this air outlet.

Some people think that there are blowers in the tunnels of coal mines. In fact, on the contrary, it should be the power of the exhaust fan, because the wind power of the blower is always exhausted.

In large underground mines, powerful exhaust fans operate at full power at each exit, with enough wind to blow a normal adult into the air.

"This vent is the road you go through every day?"

Ye Feng looks at the wind devil coming out from a small exit. It's estimated that his strength is level 11 or level 2 in nature. Besides Ye Feng and long Ying, who can barely stand, song Hu and others have to climb forward slowly on the ground.

"In the past, we had other tunnels that could bypass the tuyere, but it was a little far away. If we went to the control room and stopped the water pump, we couldn't go back without going through the tuyere!"

Maple Leaf Xuan said, looking at his words can only guess out loud.

"Tighten my hand!" Ye Feng reaches out his hand to hold song Hu. Fang shaozong song Yuxuan pulls song Hu's arm to death. Several people stand up and walk step by step towards the front vent.

"Dong Dong..."

Just as the crowd was about to get close to the vent, there were bursts of vibration from Ye Feng's sharp feeling. Turning around, a group of people were chasing the vent in front of him like locusts.

"Don't look back, step by step!" Ye Feng condenses the voice into a thin line and shoots it directly into these people's ears. The air outlet of this tunnel is gourd shaped. There is a dark tunnel about 20 meters long in the middle of the tunnel, which is more than 10 meters wide on both sides. The width of this tunnel is less than 3 meters. Originally, the extremely strong wind force in the tunnel suddenly shrinks here, and the wind force is the most violent. Ye Feng and

longying even have to bend down to move forward a little bit.

Song Yuxuan and Fang shaozong, two ordinary people behind, are lying on the ground now. They can only move forward a little bit by holding song Hu's wrist.

Rao is so, two people's bodies or not of lightly fly up.

Because of the existence of water layer in the tunnel below, the air is extremely humid. The wind is very strong in the tunnel more than ten meters away, and even some ordinary lighting facilities do not exist. The walls and the ground are extremely slippery, even if you take one step, you will slip half a step.

"Damn it

At this time, song Hu, who was leaning over, slipped and half knelt on the ground. The imbalance made him and the two people behind him fly at the same time.

Ye Feng waves his hand and holds it directly on Song Hu's flying wrist. Long Ying waves it in time. It's dangerous and dangerous to seal the joint of the three with ice.

"Brother, the wind is too strong!" Dragon shadow called out, "do you want to push me to the front? Let me open a road with ice in front of you!"

Ye Feng looked at the three people flying behind, Fang shaozong's broken leg has been able to fly out of the roadway, behind him a group of ferocious people are desperately forward, but the strong wind blowing, let them not close to blow out.

"Save Help

Fang shaozong looked at the demagogues behind him and kept wailing. At this time, he knew what a moment of life and death was.

"Walk against the wall!" Feeling more and more fierce wind ahead, Ye Feng pulled a few people to stick to the wall.

Dragon shadow slowly forward, hands gradually issued a strong blue light, the water droplets from the wind condensed into a wind wing cover behind the crowd.

"Extremely cold world!"

The yellow light in longying's eyes is more and more abundant, and the water layer in contact with the blue light in his hand can't help sending out ice flowers. Gradually, a barrier made of cold ice slowly appears in longying's hand.

The barrier made of ice is pasted on the wall at a very low angle, and a large amount of wind blows through the barrier, leaving them a small safe area.

With this safe area, song Hu and other talents took a breath of relief.

Against the wind of level 12, the blue light of longying's hands became more and more powerful. Ye Feng even felt that the blue light of longying's hands slowly began to spread on his hands. Even the head of longying gradually turned into a dragon head, and even two blue dragon whiskers slowly floated away.

"Dragon shadow!" Ye Feng wakes up the boy, and then takes him to the side.

At this time, Ye Feng with people just subconsciously through the vent. After passing, they stuck tightly to the wall on one side of the roadway and took a deep breath.

"Brother, I'm a little sleepy!"

At this time, the head of dragon shadow seems to be a little dizzy, lazily leaning on Ye Feng's side.

"Sleep when you're sleepy!" Ye Feng holds the Dragon shadow in his arms.

Then thinking about looking behind him, song Hu has pulled the two people behind him out of the lane. Most of the Gu people behind him can't hold the strong wind in the vent. With this lane, at least they are safe for the time being."Song Hu, turn on the switch of the water pump. Song Yuxuan, take me to the control room to find C4!"

Ye Feng turned his head and gave orders. He turned his head and took all the people down the wind gate.

Area C is the quietest area in the room of a laneway. Usually, it is mainly for the reception of individual guests, that is, people who want to see a little. However, this place is far away from the ghost city Ye Feng met when he came down, so he can hardly touch the core area. Walking through a cross intersection, song Hu greets several people, and then goes to the other side, where is the control room. In the deep of the roadway, two huge water pump devices are suspended with driftwood. Once the overflow reaches a certain level, the water pump will start automatically, and then discharge the water level to a certain level, and the power will be cut off automatically.

Because of the complexity of underground water level in Ancheng, generally speaking, deep mines need to establish a water outlet point in the deepest part of the mine. According to the principle of water level balance, as long as there is no water at the lowest water level point, the safety of other tunnels can be guaranteed.

After Song Hu left, song Yuxuan helped Fang shaozong limp to the next control room,

outside the control room, after walking two directions along the corridor, he came to the front of the elevator.

This is an elevator with only guardrails on the outside, like a rectangular basket for cleaning glass in a high-rise building, with two lots of guardrails on the side.

"When we get there, just press the switch button here, and the elevator will take us up.

Song Yuxuan nervously said, and then he opened the cabinet in the duty room next to the elevator, in which there was a small safe. After pressing the button and dialing it a few times, the safe was called with a "Bata" sound, which was several packets of gray plastic objects.

When you take it out, there's a device similar to a walkie talkie, and there's a black handshake on it.

"Mr. Ye, this is the stored C...."

"Don't move" Ye Feng looked at the things in Song Yuxuan's hands, drank a loud, is a strong bomb, how can you take it casually.
