One Thousand Six Hundred and Twenty-One Stage Victory

"I'm fine!" Ouyang Ping shook his head and stood up.

"I'm fine too!" Luo Qi turned over and sat up straight, looking around, "How are you guys doing?"

"fine!"

"I'm fine too!"

Several soldiers slowly got up, except that they moved a little slower, there was nothing wrong with them.

This was not because they were injured in the explosion, but because they deliberately slowed down their movements and took the opportunity to check whether they were injured when they were not sure whether their bodies were injured.

Ye Han immediately breathed a sigh of relief when he saw this. Luo Qi and the few soldiers around him were closest to the exit. Even they were fine, and the others were definitely fine.

The soldiers were all fine, and Ye Han's attention immediately turned to the exit.

The cover on the exit was now torn apart and scattered among several soldiers. The soldiers who were hit by the cover were disgraced and covered in dust.

Ye Han took a few steps past the soldiers, lay on the exit and looked down.

The originally neat storage room was in a mess. The pile of boxes blocking the door were flying everywhere, and a few thin flames were slowly burning on the cartons.

In addition, there are a few half-dead springtails in the storage room, and there are more springtails outside. Some of them make a little movement, but most of them are completely unresponsive.

Luo Qi came close to Ye Han: "The oxygen content is insufficient, carbon monoxide and carbon dioxide exceed the standards, and there are other harmful gases."

Ye Han took off the rifle from his back, turned over and jumped into the storage room: "Follow me!"

The soldiers jumped down one after another and quickly formed a defensive formation.

Ye Han waved his hand, and the team immediately left the storage room and walked straight along the corridor.

The corridors were littered with corpses of springtails, including corpses killed in previous battles and unlucky ones who died in the explosion. The corpses of bugs were piled on top of each other in a thick layer. Every step the soldiers took, they had to Raise your leg to hit the insect and step forward.

The closer to the gas well, the more obvious the burning marks on the insects' bodies were. When they were near the gas well, both the insects and the wall were burnt to a crisp and black.

When passing the gas well, Ye Han took a look inside and found that the wellhead was silently spraying blue flames outwards. Although the scale was smaller, it reminded Ye Han of the high-rise flames in the oil field. A natural gas torch that keeps burning.

He couldn't help but worry a little. If the fire kept burning into the coal seam, would it cause another round of explosions?

Fortunately, the valve was still intact. Ye Han quickly ordered two soldiers to go in and close the valve tightly... It was really no one. After such a serious explosion, the equipment in the gas well room was actually intact. Even the pipe was only broken at the one where the bomb was placed. Other than that, the only trace left behind by the explosion is black smoke that can be seen everywhere.

Ye Han couldn't help but secretly screamed at his luck. Fortunately, Ouyang Ping didn't put the bomb on the main pipe, otherwise this place would be inaccessible.

In fact, it is not surprising, because this is the center of the explosion and the place where the flammable gas is the most concentrated. Since the proportion of flammable gas is too high and the oxygen content is insufficient, there will be no explosion here at all. The explosive can only ignite the combustible gas here, and then from there. It slowly spreads out from here.

The closer to the air well, the more serious the blackening of the walls and insect corpses is because of this.

As the flame gradually extends outward, the concentration of combustible gas in the air gradually decreases. When the concentration of combustible gas drops to the level where it can explode, a big explosion inevitably occurs.

It's unclear how wide the explosion was, but Ye Han felt that this explosion could kill more than 70% of the bugs.

At the end of the corridor is an intersection. From the blackened street sign, it can be found that this is the "Central Intersection" located in the middle of the North Third District.

Now, like the corridor, there are charred corpses of giant insects everywhere.

After determining the direction of the target, the team continued to move forward. The farther they went, the cleaner the insect corpses became. After walking a few streets, the black color left by burning could no longer be seen on the insects and the walls, but the insects here were also dead. I can't die anymore.

Ye Han believes that these insects probably died of suffocation.

In this way, the team encountered no resistance along the way.

It wasn't until they got close to the target, which was the hole in the protective wall, that they discovered a few giant insects that were still alive.

This is nothing, everyone was surprised to find that several springtails were getting in through the holes in the parapet wall. Unfortunately, the air in the North Third District was not circulated. They were fine when they first came in, but after a few steps they became drunk. He staggered as if he was in trouble, and soon fell to the ground weakly.

Ye Han couldn't help but laugh out loud. If he entered the North Third District at this time, wouldn't he be seeking death?

He waved his hand forward: "Come on!"

The soldiers swarmed forward with steel bars and smashed all the living springtails to death.

Ye Han was filled with emotion. It was so painful for these springtails to die. It was a pity that they didn't understand what it meant to be depressed. Otherwise, he would have to take a good look at what these insects looked like before they died.

Isn’t there such a saying? I just like to see how you can't stand me and can't kill me!

The number of springtails was more than expected. The soldiers worked hard for more than ten minutes before killing the last springtail. Ouyang Ping immediately stood up and filled the hole in the wall with explosives himself.

There was a muffled sound, the ground shook, and the hole in the protective wall was buried by the landslide.

The mission was finally completed, and the soldiers breathed a sigh of relief.

However, there must be giant insects that escaped in the North Third District, and the order given to Ye Han from above was to eliminate all bugs that invaded the dungeon. Therefore, Ye Han ordered the soldiers to continue their efforts to completely clean up the North Third District and strive to eliminate them in the shortest time. All giant bugs.

And not only the North Third District has giant insects left, the entire occupied area, or the entire underground city except the core area, has been infiltrated by the insect swarm. According to the order of the superiors, they must be cleaned up one by one until all the insects are eliminated.

There are definitely not so many remaining insects, but the distribution range is too wide, so it is definitely not so easy to clear them out.

The soldiers acted quickly, searching for lone giant insects in groups. Xiao Yuan, who received the news, also rushed to the North Third District soon after. The team of more than 30 people spent two full days to thoroughly clean up the North Third District.

Next, the underground city organized a large number of people to enter the North Third District, and all the building materials stored in the underground city were sent to the North Third District, and the retaining wall was fully reinforced. Half of the North Third District was directly transformed into a maze-like protection system, greatly enhancing the defense of the retaining wall.

Ye Han really couldn't understand the above brain hole. Anyone with a little military knowledge knows that offense is the best defense. The underground city has never been a fortress against the enemy, but a place to preserve the seeds of civilization!

In other words, what a dungeon needs most is a hidden location that is difficult to be discovered by aliens, rather than a super strong defense level that allows one to roll up their sleeves and fight the aliens to the death!
