Looking at the entrance with the lid lifted in front of me, it was dark inside and lacked visibility.
The sewer entrance itself is in a very remote location, in a corner between buildings, and is highly protected from light.
The sky has completely darkened, which means it has officially entered night.
Considering that the bottom itself can block the sun's rays, even entering during the day will not help, so it is the best way to rush in immediately and destroy the lair of those special zombies.
Thinking of this, Yang Ming began to arrange the next plan.
First, throw an ultraviolet flare down and use its characteristics to drive away the special zombies still near the sewer entrance.
When Carters lit a flare and threw it, there were indeed screams coming from it, and the sound became smaller and smaller, indicating that they began to flee.
Then let Theia send drones and ground robots into it first, explore the internal structure in advance, unlock part of the map first, and see if it is suitable to infiltrate.
After a while, the news came.
[Theia: This sewer is very large. It is the most important underground building in the city. It is connected to a direct river. Don’t worry, there is enough space to move around. Moreover, it has been closed for a long time, and the water source is relatively clean. 】
Yang Ming conveyed the information to the other three, and they expressed their intention to go down together.
So after Yang Ming packed up the equipment, he jumped in first, followed by Carters, Lesia, and Ai Xueer.
Since a small part of the ultraviolet flare was still burning and emitting a faint light, Yang Ming was able to see the surroundings clearly. Indeed, as Theia said, the internal space was very large.
The main walking roads are on both sides, which can accommodate two or three people walking side by side at the same time. There is a waterway in the middle, which has some flow and is not very fast.
Yang Ming and his team's jumping ability made it easy to cross the waterway.
The underground waterways are generally in a network structure and extend in all directions, making it relatively easy to get lost.
At this time, just concentrate on waiting for the pathfinding machine to convey the route map. Yang Ming decided that everyone should act together on a certain route.
Since the purpose was not very strong, it could be relatively casual, so the group of people started moving in one of the directions.
The specific rule is that whenever you see a fork in the road ahead that needs to be turned and you can't see the corner, let the ground robot go explore the path.
This robot is equipped with a lighting system and various sensors, which can identify objects in dim environments, which is very convenient.
As for the back, as long as you explore a section of the road, throw an ultraviolet flare into the middle of it.
During the burning period, Yang Ming and his group will be right on the path of the radiation, so there will always be UV protection behind them, which can effectively prevent sneak attacks.
The conclusion that can be drawn so far is that those special zombies will howl loudly involuntarily when exposed to ultraviolet rays. In such a closed environment, it is very helpful to hear the sound and identify their location.
However, precisely because it is easy to hear any movement, for them with good hearing, their own position is also easy to grasp.
If they are discovered, they should be discovered. If they are willing to take the initiative, it is a good thing, so that they can be eliminated faster.
But the zombies who escaped into the sewers just now were responsible for investigation. They had witnessed the previous battle scene in the center of the high-rise buildings. They must have known how powerful Yang Ming and his group were in combat, and they probably did not dare to act rashly again.
This is good, as it avoids being harassed before finding the lair of special zombies, and as soon as you start being attacked desperately by them, it means that you are almost close to your destination.
In this way, relying on ground robots and drones to explore the path, the entire sewer was gradually clarified. In less than an hour, many of the machines released reached the end.
The machine will return to the original path and continue walking to places it has not yet visited. The efficiency of Theia's precise path planning can be said to be very high.
Yang Ming's side seemed very casual. Although everyone tensed up and paid attention to their surroundings, the movement speed was actually very slow, and they had to look forward as well as backward.
It can only be said that the most important thing is to participate. After all, there is an additional goal of attracting the attention of zombies. As long as they can make them nervous because of this matter and thus ignore those drones that are the main force, it will be considered a success.
Time passed by, and finding the lair of the special zombie was no longer suspenseful.
The commotion at this time really began to increase, and more and more signs of biological activity could be heard in the originally silent sewer.
[Yang Ming: There are a lot of zombies around us, be careful.]
Using the [spiritual link] to sound the alarm, everyone immediately stopped and each faced one direction.
The current location is relatively easy to deal with. Except for the wall behind it, there are branch roads in the other three directions, but they are all long roads. There are no other secret passages. If you want to make a surprise attack, you must run for a while.
On the road facing Yang Ming's wall, Lesia is on the right side of Yang Ming, Ai Xue'er is on the left, and Carters is in the swing position, free to choose the direction of support.
The increasingly loud sounds such as footsteps and roars indicate that they are indeed planning to fight this time. If this is the case, let's do it.
Almost at the same time, zombies appeared at all three intersections. There were a lot of them, and they seemed to want to charge at them with all their strength.
It is worth mentioning that the special zombies in this scene are really strange. Maybe because he wanted to make full use of the terrain, Yang Ming discovered that they could actually climb on the wall.
Just like a gecko, it can cling to the left and right sides or even the ceiling with its four legs. Its joints are severely deformed and it has completely adapted to this way of movement.
Naturally, this action mode cannot be too fast, but fortunately, it can make full use of space. For a while, the entire sewer was crowded with special zombies, and they all moved in together.
Yang Ming quickly threw small iron balls forward. Although there were a lot of them, they could be quite large at the same time. Their lethality was also very good. If they hit, they could be killed on the spot.
However, the number of opponents is also very large, so they can only continuously take out iron balls from the compressor, activate their left and right hands at the same time, and throw them alternately.
Lesia dual-wields submachine guns and can shoot at zombies in all directions, and her disarming ability is superb, and she can automatically control the magazine to change bullets.
In addition to Lesia having a spare magazine on her body, Yang Ming only needs to turn on the compressor and take the time to throw the magazine at her. It will automatically float in the air and surround her, waiting for ammunition.
As for Ai Xueer, Yang Ming originally thought that she would be more difficult to cope with this kind of strange tide, but unexpectedly she performed well.
She mainly relies on stasis arrows to attack. In fact, in this case, it may be better to use explosive arrows, which can knock down a piece of enemies with one arrow.
However, the space here is too small, and the sound waves generated by the explosion will be very large, which will not only further alarm the zombies, but also affect your own ears, so the reason for not using it can be explained clearly.
