"Throw all the iron balls out! Twenty meters away, listen to my command and shoot again!"

Patting Dongzi on the shoulder, Lin Yi whispered.

Sakura Kitano took out a silver pistol and handed it over, "Here you go?"

"No, I'm better at using bows and arrows. He smiled indifferently.

"Can a bow and arrow be useful as a modern weapon?"

Kitano Sakura muttered, her eyes strange, but she still held a pistol, knelt on one knee in front of a hole, and made an aiming motion.

The rampaging zombie horde poured in like a flood and reached twenty meters away from the research center.

"Ready—"

Lin Yi's right hand was raised into a fist, and his left hand felt out a charged bullet.

Unlike the materials needed to craft the Iron Frame and Iron Ball, the Charge Bullet is more difficult to find, so only four were made.

He and Ma Chuanbai are two of them.

Nodding at Ma Chuanbai, the two of them threw out the charge bomb outside the hole!

"Zizi!"

The electric current is emitted from the inside of the oval-shaped charge bomb and falls to the outside.

"Boom!"

There was a loud bang, and blue electricity rushed out, and a dazzling white light shone on the clearing in front of it.

Suddenly, the outside was as bright as day, and even the wriggling veins on the rampaging zombies could be seen clearly.

The zombies within fifty meters of the charge bomb were concentrated by the violent current, and their bodies trembled continuously, and a burning smell emanated from the rotten skin......

"Wow!"

Dozens of berserk zombies fell straight to the ground, and a small mountain was piled up again.

Dongzi, who was sweating profusely, shouted violently and pulled the trigger!

"Bang bang bang!"

"Da Da Da!"

The rain of bullets suddenly broke out!

The rifle shook, the muzzle sparks flew in all directions, and a shuttle bullet flew out of the rain!

Intensive fire swept down a whole row of zombies.

But there were still a lot of rampaging zombies who had dodged the bullets and jumped to the side, and one of them stretched out a hand and grabbed it directly into the hole!

The smell of blood rushed to his face, and the soldiers guarding the entrance of the cave were changing their magazines, and their faces turned blue with shock.

"Get out of the way!"

Kitano Sakura shouted and kicked his subordinates away, and the silver pistol "bang" shot bullets twice, and the zombie's head outside exploded like a watermelon!

"Keep firing and sweep away the zombies outside the door!"

She turned her head and said loudly.

There was already a knock outside the iron door, and more than a dozen zombies pounced on it, but they didn't know that the door was pulled up, and they just hit the iron door with their heads and body limbs in vain.

"Boom!"

"Boom!"

"Boom!"

It's like death is knocking on the door.

"Brother Leg, these zombies are just too stupid, I don't think we need to snipe them at all, just let them hit them!"

Ma Chuanbai wiped the fine sweat from his forehead and grinned.

Lin Yi shook his head, although zombies only have brute strength, it doesn't mean that they won't use other methods to get in.

"Kill, kill, kill!"

Approaching the opening of the gate, Dongzi screamed as hard as he could, clutching the trigger until a puff of white smoke came out of the muzzle.

He gritted his teeth, put on a rifle again, and glanced out of the cave by the way, but his expression immediately changed.

"Sir, Mr. Lin, it's no good!" his voice was alarmed: "Those zombies, they're building ladders!"

Ladder ride?

Lin Yi was stunned for a moment, and then looked outside the entrance of the cave, and he was shocked.

No less than two or three hundred zombie corpses had fallen outside the research center, and some of the zombie corpses were piled up against the wall, and the zombies that came one after another stepped on these corpse mountains and climbed up.

This is taking a "human ladder"!

The sound of fingernails scratching at the concrete wall sounded, and many zombies slid down, but continued to crawl up a moment later.

"Fuck, it's all ......"

After scolding angrily, Lin Yi turned around worriedly, looked at the ventilation hole on the top, and said coldly: "Chief Kitano, guard the gate with me...... Dongzi, you take half of the people and stare at the ventilation hole!"

The walls of the R&D center are several meters thick, and the mezzanine inside is made of molten steel, which is impossible for even the laser rays of the Raging Demon Hunter to penetrate.

But once they're inside, it's different.

Dongzi nodded, nodded a few people, and ran back with guns, five or six tall soldiers, rifles pointing upwards, staring nervously upward.

"Da Da Da ......"

The sound of scattered footsteps finally sounded from the top.

Everyone present gasped.

Zhou Yu and Su You couldn't sit still, and the two retreated to the door of the production room and took out their weapons.

After a few seconds, the zombies running around on the top finally discovered the existence of the ventilation hole.

A zombie clings to the sides of the cave with both hands and sticks a head out.

The flesh on his entire face was gone, and blood was dripping from the corners of his mouth.

"Die, dog!"

A soldier yelled and pulled the trigger!

The bullet fired, and the zombie was shot in the head!

Then, more zombies reached for the vents.

"Can't let them down, don't save bullets, give me a hard shot!"

The muzzle fire dragon bursts out!

The deafening sound of gunfire deafed almost everyone in the stadium!

But at this critical moment, no one dropped the chain, everyone was red-eyed, and they wanted to beat these monsters into flesh!

The R&D center that was flooded by the zombie tide was stunned that no zombie could get in!

Impenetrable as a fortress!

Ten minutes later, another wave of zombies came......

Twenty minutes later, the heavy rain outside still did not stop, but the number of zombies outside finally began to slowly decrease.

Everyone took advantage of the short break to adjust their equipment.

Lin Yi frowned, glanced back, and sure enough, the bullets were about to run out.

If there is another wave of zombies, it is estimated that it will not be able to hold on.

Just as he was thinking about it, Ma Chuanbai suddenly grabbed his arm, and his two lips trembled: ", brother leg, let's have a big deal!"

"Look the, what's that?"

Following his chubby fingers, he saw that next to the green belt fifty meters away, a zombie rushing here suddenly stopped.

A second later, a large black spike pierced its body and threw it out!

Kitano Sakura also saw this scene, and her pretty face pulled down: "...... Do you think it's like a spider's foot?"

“...... Spider"

Lin Yi opened his mouth, felt out a charge bomb, and threw it vigorously along the hole.

The charge bomb burst open after three seconds, and four or five more zombies twitched, and a burst of white light enveloped the open space outside.

Then, a strange hissing sounded, and a black behemoth flashed out of the rain curtain and slowly moved forward.

"Really...... Is it a spider?"

The people guarding the door all widened their eyes and swallowed their saliva.
