I check in daily in CF World

The basic principle of the operation of the electric detonator is to rely on the instantaneous current to form a transient large current, and then cooperate with the detonator, and the installed high explosives.

As long as the remote control button is pressed, the switch of current in the detonator will be turned on instantly, and then the effect of detonation will be achieved.

"Everyone step back, this detonator is an instantaneous electric detonator, so as not to be injured by mistake. The night rose girl holding the switch in her hand turned around and said to the others that

the detonators we are unlikely to encounter in our lives are classified according to time, and if they are classified according to time, they are roughly the following types: instantaneous, millisecond delay, half-second delay, second delay, coal mine "

I see that this wall is also a little thick, don't you need to make a hole and blast it?"

You underestimate the power of the C4 bomb, although this wall is thick, but after a long period of thermal expansion, contraction and weathering, it is not as strong and hard as you imagined.

Just pick the point of the explosion along the crack, and I promise that after the boom, a new door will open in front of you. The

Night Rose girl with the remote control in her hand pushed the glasses on her face, looking at Su Chenfeng with smiling eyes, with a Xi tone.

Su Chenfeng swallowed his saliva, sure enough, the squinting eyes are all monsters, how can any girl like to blast this kind of thing, you must be careful in the future.

"It's okay Xueqi, let's start breaking the wall now. Sophia made a gesture

of the beginning, and the slender hands pressed the start button of the remote control, and with a bang, a large rectangular hole was opened in the thick wall.

Although there were a few large cracks in the wall, there was no other damage, and in general the location of the bombing site was very well chosen.

Through this hole in the wall, Su Chenfeng walked into the abandoned smelting factory.

"The

Eye of War, open!" With the opening of the Eye of War, the circular map with Su Chenfeng himself as the center and a radius of 500 meters was all displayed in front of him.

After a simple glance, the scene presented also made Su Chenfeng stunned, and the colors that shone into the retina were all blue and green. (The blue logo represents allies, and the green logo represents Biochemical Ghosts.)

And the green signs make up a large part, almost 2 to 3 times more than the blue signs, and they play a very wide and long range, forming a clear path.

If you really rush into this biochemical laboratory, you will definitely suffer a big loss.

This amount alone is already the biggest battle Su Chenfeng has seen so far, and it must be super difficult to retreat from there.

"All of them, as originally planned, in groups of four, split up to find special items or access to the laboratory in the factory.

After Sophia gave the order, everyone immediately set out, and if there were really four or five people in this large smelting plant, it would take a little more time.

The A-level Eye of War can't show a perfect three-dimensional map, so in Su Chenfeng's eyes, these blue-green logos are superimposed on each other, although it is a bit confusing, but there are still traces to follow.

Su Chenfeng wandered on this path full of biochemical ghosts, trying to find the entrance to the underground biochemical laboratory, otherwise these monsters would be stranded here, and one day they would come out of the underground space.

More than 40 people scattered around the abandoned smelting plant, carefully examining every detail, and finally found an unusual place after ten minutes.

"Report to the Captain, a suspicious locked room has been found. At this time, a night rose girl walked up to Sophia and explained the situation to her,

"Let's go, let's go and see." After

Su Chenfeng and the others got there, the lock on the door had been opened.

"The cylinder of this lock didn't rust, so I opened it. Erin stood there, with a small black lock in her hand,

and when she opened the door, she realized that there were dusty machines or steel-cutting equipment in it.

"There's a lot of dust in this house, and it should have been abandoned for a few days. Natasha said

, "The normal elimination of the old machines that have been replaced is completely recyclable by the manufacturer, or directly sold at a low price, there is no need to hoard here, and it is placed indiscriminately and irregularly."

The machines placed here are very well preserved, the parts are very little worn, and the copper paint is still so smooth that it doesn't take long at first glance. Su Chenfeng blew away the dust and stroked the surface of these machines

, "Tina, when was this smelting factory taken over by someone else? When was it officially declared closed?" Sophia seemed to think of something, and immediately asked the people around

her, "This factory has been in normal production until it was bought at a large price eight years ago, and the business deteriorated, until five years ago, when it was declared completely bankrupt.

"It's really interesting, since this factory has thrown a lot of money in your hands, you should just throw it out.

This land, this equipment, this machine should be sold, and quickly raise back a little money as the capital for a comeback.

Unexpectedly, he chose to stop work and abandon it in his hands, and he was unwilling to sell this factory, which is not like what a businessman can do. Su Chenfeng smiled

, "This kind of metal smelting plant will generally be listed as a national heavy industry protection zone, and there will be state subsidies. As long as there is a little business means and brains, it will not be bankrupt. "Anna is standing on the sidelines

" Not really, this large heavy industry factory is a gold-swallowing beast.

If you don't have enough money, don't try to keep it running, bankruptcy is a possibility.

The point is that the financier behind the scenes would rather waste money and make a loss-making deal than sell the factory.

Unless there is something more important here than money, or the person behind this is not a businessman at all.

After Su Chenfeng said these words, he beckoned the others, used pulleys and wire ropes and other tools to simply make a lifting frame, and cooperated with others to move these discarded equipment to the open space and clear out a spacious space.

At this time, there was only a black-gray steel plate left on the ground in the center of the whole room, and when this steel plate was lifted and stood on the wall, a huge manhole cover was found, about two meters in diameter.

"Looks like this is the underground passage to that biochemical lab.

Everyone put on their gas masks, opened the manhole cover of this passage, and was always ready to fight. Su Chenfeng said solemnly to the people around

him, "This is the same as a normal manhole cover, it is not locked at all, no wonder these large machines need to be pressed." After Su Chenfeng opened it with both hands alone

, a dark hole was finally revealed, "What are you going to do?" Natasha walked up to Su Chenfeng, and her dark blue eyes were silently asking

, "If you want to attract biochemical ghosts, it is nothing more than the following three points: sound, light, and blood."

Take out the bucket of animal blood I want you to prepare, pour that blood into this passage, and combine it with flashbangs and stuff like that, and you're sure to attract biochemical ghosts. Then

two maidens of the Night Rose carried a bucket of red liquid and poured it into the bottomless passage.

"I've put anticoagulants in the bucket, but the elk's blood is a little clumpy, so it doesn't affect the result.

"It doesn't matter, the monsters that can survive in this biochemical laboratory up to now are like sharks that have been hungry for ten days, and they will pounce frantically when they smell the slightest smell of blood.

Su Chenfeng took out another flashbang from his body, and after tearing off the safety tab, he threw down the underground passage.

The flashbang fell to the bottom of the tunnel with a "bang", producing a dazzling bright light after a few seconds, and at the same time emitting a huge noise of 170~200 decibels.

After the flashbang took its effect, 1/3 of the green signs on the Eye of War began to move, and they quickly ran in the direction of the underground passage from their original stationary or slow-moving state.

In this exceptionally quiet abandoned factory, there was a sudden sound of heavy and complicated footsteps, and everyone's hearts were raised.

Su Chenfeng summoned the others to come here: "Some people have used military flashlights to illuminate this place for me, only in this way can I attract enough biochemical ghosts."

The other part of the people were armed with guns, and as soon as these monsters showed their heads, they shot them to death, aiming them at the head or chest as much as possible.

After Su Chenfeng finished speaking, he immediately surrounded two teams, one of which shone a flashlight at the bottom of this underground passage, and the other pair was always ready with a firearm in their hands.

Finally, a green figure broke through the darkness and was exposed to everyone's field of vision.

"Fire!".
