Armor Frenzy

Handing over control of the dungeon not only did not make Ye Han feel lost, but he was greatly relieved.

To tell the truth, he is really not suitable for this kind of job of managing people. Thousands of people have to worry about eating, drinking and lhasa. Just thinking about it makes his head feel as big as a fight.

After the delivery, Ye Han was freed from the complicated affairs, and devoted himself to dealing with military issues and dealing with the giant insects in the city.

The marines' extermination operation was very effective, but it didn't take long for the swarm to recover, and it was clear that another bug had hit the tunnel and got into the dungeon.

Now it's going to be troublesome. If it's just to eliminate more insects, then Ye Han doesn't need to care about it. He just needs to send troops to clear up day after day, and he can continue to eliminate giant insects.

But the task given to him above is to destroy the insect swarm that invades the dungeon, not to consume the strength of the insect swarm here.

In this case, destroying the swarm has been a beautiful **** as long as the passage on the parapet is still there.

In order to end this annoying battle as soon as possible, Ye Han gathered Xiao Yuan and others together for a meeting.

At the meeting, Ye Han sent a floor plan to others: "This is the third north area of ​​the dungeon, the area where the insect swarms dug through the retaining wall. What we have to do is to find a way to block the hole in the wall of the third north area! "

The floor plan of West Sixth Fourth is filled with irregular polygons of various sizes. Each polygon is a residential area of ​​the dungeon, and each area is filled with squares representing buildings and colors representing passages. line.

Among them, the core area is the largest, and the other areas are large and small. The large one can accommodate thousands of people, and the small one can hold hundreds of people.

The North Third District is a medium-sized residential area. According to the markings on the map, there are more than 700 residents in the North Third District.

"Captain, do you have a plan?" Xiao Yuan asked.

"We won't come to you if we have it." Ye Han said.

Ouyang Ping said: "It's not difficult to blow up the passage, but the blasted passage can't stop the insect swarm at all. It will be dug up in a few days at most. We must find another way to repair the protective wall!"

"This is not a problem." Ye Han said, "The underground city has a lot of building materials in reserve, and you can also ask for support from above. The question now is how to blow up this passage!"

Xiao Yuan said: "The place is full of bugs. We have too few people. It is better to find the exit of the passage. It is more convenient to fry from the outside."

"It's difficult." Ye Han said, "Ningwuguan has not moved, and has been observing for several days without finding any abnormality."

Luo Qi said: "The bug must have come from the ground. The exit from the outside may be hundreds of kilometers away. It's not easy to start from the outside..."

"So you can only find a way from the inside?" Ouyang Ping scratched his scalp vigorously, "We are separated from the North Third District by several districts, and each district has a large group of insects, and a strong attack will definitely not work, unless you hit them one by one..."

"Don't make trouble." Xiao Yuan said, "We're just these few people, there are so many bugs over there, and there's that passage in the back, how many people are killed to make up for it, and when will we be able to beat them?"

Luo Qi said hesitantly, "How about blowing up all the passages?"

Xiao Yuan spread his hands: "How do we get there?"

Ouyang Ping thought for a while and said, "Why don't you ask the core area? Maybe they have a solution."

Ye Han felt that it made sense, immediately contacted the core area, and directly called Director Qu, who had just been in office for a few days. A few minutes later, Ye Han got another floor plan and shared it with others.

This floor plan is smaller than the previous one. There are still more than a dozen different districts, large and small, but the size of each district has been reduced a lot. Some thin red lines start from the core area and divide all the residential areas. strung together.

Xiao Yuan asked in surprise: "What is this?"

Ye Han couldn't hide the excitement on his face: "This is the secret door left during construction!"

"Ah?" Luo Qi couldn't believe his ears, "There are secret doors in the underground city?"

Ye Han smiled and said: "This is a map of the maintenance passages of the underground city. These passages are as secret as sewers, connecting the core area and all the residential areas!"

Several people looked at each other in disbelief.

Xiao Yuan said: "Captain, this is too unfortunate, isn't it?"

Ye Han said: "I also think it's too coincidental, but Director Qu doesn't need to fool us, right?"

"That's it... What are the lengths and widths of these passages? Can they hold our armor?"

"Seventy centimeters in width and two meters in height, it's no problem to install armor." Ye Han said, "But Director Qu also said that there are still many pipelines in the passage, and whether the armor can go in can't be concluded now... In this way, Xiao Yuan, you immediately arrange for two people to come and see!"

"Okay!" Xiao Yuan agreed.

Ye Han said again: "Assuming the passage is passable, then our plan will be easy to handle. My idea is to make a noise near the north three districts first, and pretend to attack with full force, and mobilize the swarm to several nearby districts. Move, take advantage of the lack of troops in the third area of ​​the north, and sneak into the third area of ​​the north by the Ouyang Ping group, set up explosives to blow up the passage, what do you think?"

Ouyang Ping said: "It's no problem to sneak into the North Third District, but once we fight with the bugs, the transferred bugs will definitely return to help, and then there will be no explosives, so I think the passage leading to the North Three Districts must be together. Blow up, isolate the three northern districts, and completely divide the insect swarm to succeed."

"Yes!" Ye Han nodded, "But how can we pack the explosives in advance without letting the bugs find it?"

"UAV?" Luo Qi said three words.

Xiao Yuan's eyes lit up: "Let's just use a drone for the passage in the North Third District!"

"You can try it!" Ye Han agreed, "Ouyang ~www.wuxiaspot.com~ arrange it right away!"

"Okay!" Ouyang Ping gave a few words over the radio, and a few soldiers who were good at blasting immediately tied explosives to the mechanical spider and carefully controlled the drone to sneak into the occupied area.

These days, the Marine Corps took the initiative to attack, and the two sides fought desperately in various occupied areas. The walls of each residential area were either penetrated by worms or exploded by explosives. Large-scale collapses can be seen everywhere, and many places are even completely turned into ruins. At first glance, it is a cave hall full of rubble, not a residential area with a field of view of only ten meters at most.

Even the main passages of each residential area were destroyed in several places by the fighting between the two sides.

Therefore, the spider does not need to walk along the passage at all. As long as it enters the occupied area, it can look for cover everywhere, and finally slowly approach the target.

If not, Ye Han would not agree to this plan.

In the beginning, everything went smoothly. The mechanical spiders kept moving between the rubble and rubble. However, there were too many bugs in the occupied area. Before the mechanical spiders could reach the place, they were discovered by the Zerglings jumping around. u
