Lao Bi and others carried explosives on their backs and calmly approached the six zombies.

These ordinary zombies walked out of the woods and walked very slowly when exposed to the sun.

Just like a machine that hasn't been lubricated for a long time, it's a little stuck.

Come closer.

Lao Bi pulled out the dagger from his thigh strap,

"Poof!"

A sharp dagger was inserted into the zombie's eyeball.

One pump.

thump!

The zombie in front of Lao Bi immediately fell to the ground.

At the same time, five other zombies were also killed by the accompanying combatants.

Their attacks are crisp and clear, and they are sure to hit with one hit.

Six zombie corpses fell in the sunshine in front of the woods.

Lao Bi looked at the woods warily, and after seeing that there were no more zombies inside, he waved behind him, and everyone walked into the woods in a triangular formation.

The other side.

Li Yu looked back and thought of a question.

"Lao He, is there any other exit from this underground cave?"

He Chao nodded without thinking:

"Yes, of course there is. There is a large entrance in the back mountain. There are two on the right side, and on the left...well, there is a very, very small entrance. That entrance is very small, and can only allow one person to pass through. And

It’s hidden by vines, so it’s hard for ordinary people to spot it.”

"Well..." Li Yu nodded slightly, and asked others to seal the other exits later.

Either don't do it, or do it all if you want to do it. This is his consistent style of doing things.

Lower your head.

Continue to watch the footage transmitted back by the drone in Qu Xing's hand.

As He Chao said last night, the space inside is larger than they imagined.

This cave shows a downward trend, with jagged rocks and stalactites hanging upside down.

Some places are low and some places rise sharply.

The drone can easily hit rocks if not careful inside, which requires Qu Xing and others to operate with great concentration.

After flying for more than a kilometer, the underground cave was still densely packed with zombies.

After seeing so many zombies, Li Yu became more determined to blow up the entrance to the cave.

"Where is the underground river you mentioned?" Li Yu asked.

"There is a small fork in the front, at the very back, on the right. Go in and go some distance inside, about a hundred meters, but that side is relatively low, making it difficult for a drone to fly in."

soon.

The drone flew to the bottom. There were more zombies at the bottom, and these zombies were all stacked together.

"Lao He, where is the intersection of the underground river you mentioned?"

He Chao stared closely at the picture on the control screen, "I remember it's on the left, left... yes, fly closer."

The drone controlled by Qu Xing flew to the left and at the same time lowered its altitude to two and a half meters.

Wuwuwu——

"Yes, this is the place."

Qu Xing looked at the fork in the road, which was only two meters long, and felt a little doubtful about life.

From the top of the zombie's head to the top of the intersection, there is only about thirty centimeters of space.

The size of their drone is already more than 20 centimeters high. If you want to fly in, you need to get stuck in the gap to operate to the limit, and the terrain inside is very complicated with twists and turns.

If it collides, it will fall off. If you control the drone to fly in, it will most likely crash.

When Li Yu saw the intersection at such a low altitude, he naturally knew that it was almost impossible for a drone to fly in.

"Is there any other entrance to the underground river?" Li Yu looked at He Chao and asked.

"No, this is the only place..."

"Um..."

Li Yu had a look of disappointment on his face. Originally, he wanted to figure out the underground river in the cave, but now it seems he has no choice but to give up.

"Let the drones fly back." Li Yu said to Qu Xing and others.

This underground cave has almost been seen. There are so many zombies in it that it is impossible to count them, but at least they should be calculated in ten thousand.

We took a helicopter all the way to Hefeng Town and couldn't see many zombies, but even if all the zombies in Hefeng Town came here, there shouldn't be so many zombies.

It's very possible that these zombies came from the underground river, but now they can't go down, and they don't know where the underground river leads to.

The height of the fork is too low for drones to enter.

There was no choice but to let Qu Xing and others control the drone to fly back.

Don't worry, if you don't reach the underground river by then, all the drones will crash and be destroyed.

....

Cave entrance.

"City Lord, we have arrived at the entrance of the cave, now we are going to place explosives."

"Well, try to blow up as much of it as possible."

Lao Bi gestured to several combatants, six or seven of whom were holding guns and looking at the entrance of the cave.

The others quickly put down the explosives on their backpacks.

Installing explosives is also a technical job, and the location and amount of ammunition are very important.

Lao Bi observed the entrance of the cave, identified several points, and placed the explosives on the corresponding points.

Suddenly, two zombies in the cave seemed to smell the human scent at the entrance of the cave and came out.

"Don't shoot!"

After Lao Bi saw these two zombies, he quickly shouted in a low voice to the people on guard behind him.

If a shot were fired, the sound would be shocking.

Once inside the cave, the sound will be amplified and the zombies inside will definitely be attracted out.

When the time comes, they will have to escape quickly.

The combatants at the back quickly put down their guns, drew out their daggers, approached the two zombies, and killed them in twos and twos.

Lao Bi swallowed nervously. The city lord said that if the bomb was to be blown deeper, more explosives would have to be put in.

He did not dare to go inside, so he could only place hundreds of kilograms of explosives one or two meters inside the cave entrance.

It's dark inside, and zombies may come out in the next second.

After quickly placing the three bags of explosives, Lao Bi quickly exited.

He quickly placed two more bags of explosives on the edge of the cave entrance, on the left and right sides.

"Wenzheng, you throw these two bags of explosives in, using your utmost strength." Lao Bi handed Wenzheng a bag of more than ten kilograms of explosives.

Wen Zheng's strength was relatively strong and he could throw it far.

He took the explosive bag, leaned back, united his waist and horse, and threw it into the darkness with all his strength.

It was thrown about seven or eight meters, and I don't know if it hit a zombie.

Roar!

There was the roar and roar of zombies inside.

This chapter is not over yet, please click on the next page to continue reading the exciting content! Wen Zheng quickly threw away the remaining bag of explosives.

"run!"

Listening to the roars of the zombies inside, Lao Bi knew that they had alerted the zombies inside, so he ran away.

The other combatants also quickly retreated and ran towards the woods behind.

Sure enough, Lao Bi took a moment to glance behind him while running, and saw more than a dozen zombies pouring out of the cave entrance, followed by a cloud of darkness.

After seeing this scene, he ran faster.

At the same time, he picked up the walkie-talkie to contact Li Yu and others outside the woods.
