Entering through the front door is definitely not feasible. Once the iron door is opened, zombies will swarm out and it will be difficult for them to deal with it.
What's more, Li Yu didn't want to waste any more bullets at this time. He had gotten a lot of grenades from the gun arsenal, but he rarely used them, but he brought out a lot this time.
They were standing at the entrance of the cave just now. If a grenade was thrown in, the cave would probably collapse. If it collapsed, it would have nothing to do with them whether there were any munitions inside.
Therefore, you cannot explode at the entrance of the cave, but there is a blank space of more than ten meters between the entrance of the cave and the iron gate.
It's just that they are difficult to deal with outside the door.
.....
Everyone began to climb, holding the long knives behind their backs, and climbed up the mountain with both hands and feet.
After everyone climbed less than 40 meters, they saw a wall on the right.
Li Yu stood at a high place and saw that behind this wall, it was connected to the front door.
So he said: "Let's go over there."
Although this wall is 5 meters high, there are many boulders crisscrossing underneath the wall. Next to this wall, there are two trees growing.
The tree is very tall. Although I can't tell what kind of tree it is, this tree grows extremely lush.
During the previous drought, many trees died directly, and some survived, but some branches were withered, and this tree was extremely strong.
The branches are intact and the leaves are green.
The tree growing out of the cracks in the stone looks extremely tough, and the hard lines on the bark seem to confirm this.
Climb up.
The trees are very close to this wall, less than 50 centimeters away. In addition, there are many shooting holes on this wall, which can be used.
Everyone climbed up from the tree and climbed to the wall in twos and twos.
After climbing up this wall, they discovered that they had now reached the top of the cave at the front door.
Behind this wall, there are three tile-roofed houses, but the green tiles are rusty and have fallen to the ground. The wooden beams inside the tile-roofed houses are dilapidated and infested with insects, and half of one house has collapsed.
This site is not well protected...
Everyone slandered.
Coming down from this wall, everyone saw a hole with a diameter of two meters behind a rock.
This hole...
Judging from the location, it should be the hole they entered just now, which means that their current position is directly above the entrance of the hole.
Li Tie used a flashlight to shine inside. It was pitch black and he couldn't see anything clearly.
This cave is full of twists and turns. When they were in the cave just now, there was no light except for the light at the cave entrance. It must be because of the rugged entrance of the cave that the light was swallowed up by twists and turns.
Li Yu took one look at the hole and walked towards the front door of the room.
Everyone followed closely behind.
As I walked, I could see a long corridor. This corridor was built on rocks, and some blue bricks were built on top. These green bricks looked extremely hard.
After so many years, it is covered with dust, and some moss has grown in the darker areas.
But the corridor is still standing, and there are still some shooting holes on it.
Looking out from the shooting port, we can see where they were at the gate just now.
The roars of zombies were heard below, and everyone walked towards the direction of the zombies' voices.
After walking less than a few dozen meters, we arrived next to the gate.
hiss!
Everyone gasped.
Fortunately, the door was not opened just now. The distance from the cave to the gate was less than 20 meters in blank space. At this time, the large iron gate was surrounded by zombies.
At a glance, there are no less than 200 zombies.
Looking down from a high position, these zombies didn't even notice them.
They were standing on a small building made of wood. The small building was built on rocks. The small building built according to local conditions looked antique and charming.
This small building leads directly to the gate, but due to its age, the steps leading down to the small building were damaged and shattered into a pile of wood chips.
The height of the small building from the ground was about 5 meters. People did not dare to step on the wooden floor of the small building, but relied on the rocks to walk on it.
This small building looks too hanging, and the wooden floor is so bumpy that it looks like it will break if you step on it.
There is a blank space between the cave and the gate, which is a good opportunity.
Throwing grenades down from here will not blow up the cave and can effectively eliminate zombies.
Li Yu said: "Throw the grenade over from here and kill them. What do you think?"
Cannon nodded and said: "Good method, that's it."
Others have no objections, and they have no better way.
In fact, Li Yu wanted to lie on top of the iron gate from the beginning, but after all, this was originally used as a fortress to resist the national army.
Above the front door, there is a 10-meter-high wall tower. This wall tower is made of solid blue bricks. Although there are many bullet holes on the surface, it is extremely smooth and it is impossible to climb up from the front door.
At this time, it is a good way for them to climb up from the side.
Li Yu glanced at Li Tie, and Li Tie understood instantly.
He held his mouth with his right hand and made a sharp whistle.
Shhh~
The whistle instantly spread throughout the area.
The sound spread to the bottom of the gate, because everything below is sealed. In front is the gate, behind is the cave, on the left is a high wall and some rocks, and on the right is where Li Yu and the others are.
Whistles echoed throughout the enclosed area.
Shhhhhhhhhhhhh
They clearly saw some strange movements among the zombies near the gate.
The zombies in the empty space between the gate and the cave turned their heads and looked in their direction.
When they saw Li Yu and the others on the high rocks, they went crazy instantly.
Come pouring in.
Li Yu communicated with everyone with his eyes, and everyone knew what to do. They all took out the grenades in their waists.
Zombies are running over.
Li Yu waited for the zombies to gather and threw the grenade down.
Then everyone leaned against the rock wall, trying to keep their bodies as close to the rock as possible.
Boom!
A loud bang!
The zombies seven or eight meters away were blown out of a vacuum zone.
Because the zombies were directly close to each other, at least dozens of zombies were killed by this explosion.
Li Tie and Li Gang also found the right opportunity and threw two grenades, which exploded where the zombies were most concentrated.
When the fifth grenade was thrown, half of the building collapsed.
Everyone was a little lucky. Fortunately, they were not standing directly on top of the small building, otherwise it would collapse.
It was immediately overwhelmed by zombies.
Amidst the roar, some more zombies emerged from the cave.
These zombies were all attracted by the sound. Seeing more than 200 more zombies, everyone was speechless. Is this cave a zombie lair?
However, it is a good thing to blow up all these zombies. Otherwise, if there are still so many zombies hiding when they go down again, it will be even more troublesome.
Lead it out first and kill it.
With the roar of grenades thrown by everyone, more and more zombies fell down.
After a while, there were only a dozen scattered zombies down there, but they were also missing arms and legs.
