Entering through the front gate was definitely out of the question; once the iron gate was opened, the zombies would swarm out, and they would be difficult to deal with.
Moreover, Li Yu didn't want to waste any more bullets at this time, but he had gotten quite a few grenades from the armory back then, which he rarely used, but he had brought out quite a few this time.
Just now, they were standing at the entrance of the Sinkhole; if they threw grenades in, the Sinkhole would probably collapse. If it collapsed, any firearms inside would be irrelevant to them.
So, they couldn't detonate at the entrance, but there was a blank area of about ten meters between the entrance and the iron gate.
It was just that they would have a hard time dealing with them from outside the gate.
Everyone began to climb, their long knives slung over their backs, and they scaled the mountain with both hands and feet.
After climbing less than 40 meters, they saw a wall on their right.
Li Yu stood at a high vantage point and, seeing this wall, realized it connected to the front gate's location.
So he said, "Let's go over there."
Although this wall was 5 meters high, there were many interlocking boulders beneath it, and beside this wall grew two trees.
The trees were very tall, and although it was impossible to tell what species they were, they grew exceptionally lush.
During the previous drought, many trees had directly withered and died, while some had survived, but some of their branches were dry and withered; yet, this tree was exceptionally resilient.
Its branches were intact, and its leaves were verdant green.
The tree, growing stubbornly from the crevices of the rocks, looked extremely tough, and the hard patterns on its bark seemed to confirm this.
Climb up.
The trees were very close to this wall, less than 50 centimeters away, and coupled with the many firing ports on this wall, they could be utilized.
Everyone climbed up this tree, and in a few swift movements, they were on top of this wall.
After getting up from this wall, they realized they had now reached the area directly above the front gate's Sinkhole.
Behind this wall were three tiled houses, but their green tiles were rusted and had fallen to the ground, and the wooden beams inside the houses were dilapidated and worm-eaten, with one house having completely collapsed on one side.
This historical site wasn't really protected, huh?
Everyone grumbled inwardly.
Coming down from this wall, everyone saw a hole with a diameter of two meters behind a rock.
This hole...
Based on its location, it should be the same hole they had entered earlier, meaning their current position was directly above the entrance of the Sinkhole.
Li Tie shone his flashlight inside; it was pitch black, and he couldn't see anything.
This Sinkhole was full of twists and turns; when they were inside, apart from the light from the entrance, there was no other light, indicating that the tortuous path of the Sinkhole must have swallowed up the light.
Li Yu glanced at this hole and then walked towards the front gate of the house.
Everyone followed closely behind.
As they walked, they saw a long corridor, which was built upon the rocks with some green bricks, and these green bricks looked extremely sturdy.
After so many years, it was covered in dust, and some moss grew in the darker areas.
But this corridor still stood firm, and it also had some firing ports.
Looking out from the firing ports, it was the location of the main entrance where they had been earlier.
The roar of zombies came from below, and everyone walked in the direction of the zombie sounds.
After walking less than a few dozen meters, they reached the side of the main entrance.
Hiss!
Everyone gasped.
Fortunately, they hadn't opened the door earlier; the blank area of less than 20 meters from the Sinkhole to the main entrance was now completely filled with zombies, tightly packed around the large iron gate.
Roughly estimated, there were no fewer than 200 zombies.
Looking down from above, these zombies hadn't discovered them yet.
They stood on a small wooden building, which was built against the rock, and the building, constructed to suit the terrain, looked ancient and charming, full of character.
This small building directly led to the main gate, but due to its age, the steps leading down from the building were damaged, crumbling into a pile of wooden debris.
The small building was about 5 meters above the ground, and everyone dared not step on its wooden floor, instead walking by relying on the rock.
This small building looked too precarious; its wooden floor was full of potholes, and it seemed like one step could cause it to crumble.
The area between the Sinkhole and the main gate was a blank space, which was a good opportunity.
Throwing grenades down from here would neither blow up the Sinkhole nor effectively eliminate the zombies.
Li Yu said, "Let's throw grenades down from here to blow them up. What do you think?"
Da Pao nodded and said, "Good idea, let's do that."
The others had no objections; besides, they had no better plan.
Actually, Li Yu had initially thought about lying on top of the iron gate, but after all, this was originally a fortress used to resist the Kuomintang army.
Above the front gate, there was a 10-meter high wall tower, built with sturdy green bricks. Although its surface had many bullet holes, it was incredibly smooth, making it impossible to climb up from the front gate.
Climbing up from the side at this moment was indeed a good method.
Li Yu glanced at Li Tie, and Li Tie instantly understood.
He pinched his mouth with his right hand and let out a sharp whistle.
Whoosh~
The whistle instantly spread throughout the area.
The sound reached below the main gate; because the area below was sealed, with the main gate in front, the Sinkhole behind, a high wall and some rocks on the left, and Li Yu's position on the right.
The whistle echoed in this confined area.
Whoosh~ Whoosh~ Whoosh~
They clearly saw some movement among the zombies near the main gate.
The zombies in the blank area between the main gate and the Sinkhole all turned their heads and looked in their direction.
Upon seeing Li Yu and the others on the high rocks, they instantly went crazy.
They surged over.
Li Yu exchanged glances with everyone, and they all knew what to do. They all took out the grenades from their waists.
The zombies ran over.
Li Yu waited for these zombies to gather, then threw the grenades down.
Immediately, everyone leaned against the rock wall, trying to press their bodies against the rock as much as possible.
Boom!
A loud bang!
A vacuum zone was created where zombies seven or eight meters away were blown away.
Because the zombies were packed very closely together, this explosion killed at least dozens of them.
Li Tie and Li Gang also seized the opportunity and threw two grenades down, both landing in the densest parts of the zombie horde.
When the fifth grenade was thrown, half of the small building suddenly collapsed.
Everyone felt a little lucky that they hadn't stood directly on the small building just now, otherwise, if it had collapsed...
They would have been directly swarmed by zombies.
Amidst the roar, some more zombies emerged from the Sinkhole.
These zombies were all attracted by the sound. Seeing the additional 200-plus zombies, everyone was a bit speechless, thinking, "Is this Sinkhole a zombie nest or something?"
However, being able to lure all these zombies out was a good thing; otherwise, if there were still so many zombies hiding when they went down again, it would be even more troublesome.
Lure them out first, then kill them.
As everyone threw grenades, amidst the roar, more and more zombies fell.
In a short while, there were only a dozen scattered zombies left below, but they were missing limbs.
"Let's go down," Li Yu said.
