Soon more than 100 people, divided into ten units, began to move down the waterway.

As for Cai Wenjie, he also followed one of the units into the sewer.

It's very dark in the sewer, but you can see it clearly by strong light flashlight and fluorescent stick.

"Be careful, don't let go of any suspicious place!"

"Yes!"

Cai Wenjie warned the soldiers around him while watching the watchful observers.

Because of wearing gas masks, the soldiers' vision has been greatly affected, so they can only move forward carefully for fear of being attacked by blood pestilence creatures that don't know where they will come from.

As he went deeper and deeper into the sewer system, Cai Wenjie found that the smell here was getting worse and worse, and a blood red mist began to appear.

You don't have to think about it. This is the blood gas emitted by the heart of blood disease, that is to say, there is definitely a heart of blood disease nearby.

Realizing this, Cai Wenjie was more careful and alert again, and the bullets in the gun were fired at any time.

Soon Cai Wenjie stopped at a corner, raised his right hand and held it in a fist shape, indicating that the people behind him stopped.

After seeing Cai Wenjie's gesture, the other soldiers immediately stopped in place and squatted down quickly.

After everyone stopped, Cai Wenjie tilted his head a little and looked at the situation outside the corner.

Sure enough, as he expected, about 30 meters from the corner, there was a blood epidemic heart attached to the wall, and it was still spitting out bleeding red gas, that is, blood gas.

The periphery of the blood epidemic heart is surrounded by blood epidemic creatures. These blood epidemic creatures are greedily breathing the blood gas emitted by the blood epidemic heart, which looks no different from those addicts.

Because of this, Cai Wenjie and others were very lucky not to be found by blood disease organisms.

Not far from the heart of the blood epidemic, Cai Wenjie immediately took out several iron boxes from his system space, which were filled with incendiary bombs and fragment grenades.

"The heart of the blood epidemic and the blood epidemic creatures surrounding the heart of the blood epidemic were found 30 meters away. To be safe, everyone came to me to get five incendiary bombs and five fragment grenades each time."

For fear of startling the snake, Cai Wenjie spoke in a low voice as much as possible, and the soldiers were not fools, so the soldiers did not answer Cai Wenjie, but came to Cai Wenjie to receive incendiary bombs and fragment grenades.

"Wait a minute, everyone keeps throwing incendiary bombs and fragment grenades at me"

"Yes!"

"Follow my orders! Work in pairs, with an interval of ten seconds. Don't stop until you finish throwing! Throw it to me!"

With CAI Wenjie's order, all the soldiers were quickly divided into five groups, and then group by group began to throw incendiary bombs and fragment grenades at the heart of the blood epidemic.

Because the interval between throwing grenades is 10 seconds, you don't have to worry about hurting your teammates. As for whether there will be flammable gas such as biogas in the sewer, you don't have to worry too much. Because the bunker has been used again for less than 24 hours, there is no way to produce biogas in the sewer.

With a burst of explosion and fire, the heart of the blood epidemic that originally released blood gas was immediately covered by the sudden fire. Because the incendiary bomb uses napalm, it is difficult to get rid of the flame once it is stuck. In addition, the heart of the blood epidemic has no way to move or move, so there is no way to deal with the sudden flame, Can only passively bear the pain and burning caused by the fire.

The greedy blood epidemic creatures around were directly torn up by the fragments produced by the explosion of fragment grenades. Many blood epidemic creatures disappeared without reaction at all.

The surviving blood epidemic creatures were also burned by the flame of the incendiary bomb. These blood epidemic creatures infected with the flame instinctively wanted to roll on the ground to extinguish the flame, but it didn't work at all. The final fate of these blood epidemic creatures was nothing more than two possibilities: one was burned to ashes by the flame of the incendiary bomb, and the other was blown to death by broken grenades.

And this is just the first wave of attack.

Ten seconds later, the second group also began to throw incendiary bombs and fragment grenades in their hands. The third group and the fourth group until the last group finished throwing incendiary bombs and fragment grenades in their hands, the heart of the blood epidemic had been burned and there was no residue left.

"Stop!"

With CAI Wenjie's order to stop throwing, all the soldiers stopped their movements.

It's not Cai Wenjie who loves these incendiary bombs and fragment grenades, but if it goes on like this, he's afraid that the whole sewer system will collapse, and most of the body of the heart of blood disease opposite has been blown into slag, so there's no need to throw it away.

"One group! Two groups!"

"Yes!"

"Go and see the heart of blood disease!"

"Yes!"

For the sake of safety, Cai Wenjie sent several people to check the heart of the blood epidemic. With the two groups carefully approaching the heart of the blood epidemic, Cai Wenjie's whole spirit is highly concentrated, and his fingers on the trigger have not been released. As long as there is something wrong on the other side, at least he can support at the first time.

Fortunately, several people were safely close to the heart of the completely dead blood epidemic. There was no accident, that is, the burning flame had some impact on the two groups

When the two groups checked the heart of blood epidemic several times through the burning flame and confirmed that there was no sign of life, they immediately spoke loudly with the people behind them.

"Safe!"

Cai Wenjie, who received the safety signal, took the rest of the people close to the heart of the blood epidemic.

Cai Wenjie, who was close to the heart of the blood epidemic, immediately heard a long lost prompt in his mind.

"Discover the energy source and start absorbing! Absorbing..., you have successfully absorbed the energy source, reward 50000 points and strengthen opportunity + 1"

Cai Wenjie didn't pay too much attention to the prompt sound, but looked at the periphery of the heart of blood disease with vigilance. Although the heart of blood disease is gone now, it doesn't mean that the creatures of blood disease are gone together.

Although the neighborhood has been covered by fire, Cai Wenjie's footsteps can not be stopped. He took out an unknown blue projectile from the system space, aimed at the area covered by fire a little, and then threw it out.

The blue bullet shot at the flame covered area at high speed. At the moment of touching the ground, the bullet burst open and scattered a large amount of blue liquid evenly on the ground.

In an instant, the ground that was still burning seemed to encounter some natural enemy. It went out in an instant, and the original high temperature around it fell to the freezing point in an instant.
