But the outer line of defense was very dilapidated, littered with burning ruins and broken corpses.

"Griffith, isn't it time for us to transfer." Luo Ze looked at the broken defense line and said, "There are still countless zombies, and this defense line can no longer support the next attack." ”

The original new and sturdy building on the defensive line is so damaged that it is impossible to find a single intact pane of glass. The walls of many of the buildings are also inlaid with huge stones, apparently entertained by the Eye Demon's throwing skills. Everywhere there are dead zombies and the corpses of the guardians.

The turret of an M1A2 crouching at the intersection was deformed by a boulder, and the barrel was twisted to 90 degrees. The mutilated limbs of a crew member hung on the rear of the car, and there was still a bullet hole in the center of the eyebrow, which was supposed to be a relief for his desecrated corpse after being killed.

The field artillery was also destroyed in the assault just now. Although there were few of them, the artillery was at the heart of the position, heavily defended by tanks, tanks, infantry, and bunkers. Being destroyed meant that the zombies once broke through the defense line and killed deep in the position.

"Yes, it's time for us to leave. But we have more to do before we leave. "Xiao Yan dismissed those novice contractors first, and let them go to the supermarket base through the river to meet; Then he took out his radio and called the captain who had taken him to Dr. Heydrich. "Did you find anything? Okay, okay. Understood, I'll be right away. ”

After receiving a confirmed answer, Xiao Yan and Luo Ze hurriedly jumped into a prepared Hummer off-road vehicle and rushed to a remote grove in Raven Park. The Captain had been waiting here for a long time, and in addition to him and his men, there were several technical soldiers who were operating the listening equipment.

"It's right down here. Doctor, let's cooperate with you fully. The explosives have been planted. The captain was serious, "My men are ready for battle." ”

"The enemy can be strong. If the situation is critical, evacuate as soon as possible. We can also use our abilities to the fullest. Xiao Yan didn't want these brave soldiers to die in vain, so he still admonished.

"Boom!"

With the detonation of powerful explosives, the soft lawn was lifted more than ten meters high, and dirt, grass roots and gravel fell like rain. The deeply buried explosives dug a large pit in the ground to a depth of 5 meters.

Xiao Yan waited for the dust to settle, and walked to the side of the big pit to look around. A huge tunnel came into view.

Xiao Yan also learned the reason for this steady stream of corpses from the contractors under Yuri just now, and in the case that the zombies have already entered the core line of defense, the original perfect listening system cannot be continued, and most of the ground drillers have infiltrated it.

The soft soil allowed the Driller to dig extremely high, and it didn't take long for the zombies to penetrate the defense line before they had already dug a deep passage.

Xiao Yan jumped down and landed steadily on the soft soil. Turning on the searchlight on his helmet, Xiao Yan took out the 3-barreled Gatling cannon he had just gotten and walked forward slowly.

Luo Ze and a group of soldiers led by the captain also jumped down and followed cautiously forward.

"What are we looking for?" The captain came up and asked in a whisper. His voice sounded dry and stammering, and he swallowed a mouthful of saliva, clearly nervous about the pitch-black environment.

"A huge worm," Xiao Yan turned his head to look at the captain's pale face, and said with a smile, "It's not very strong, and you can kill it by gathering fire." In such a tunnel, it has nowhere to escape. ”

Although he didn't know Yuri's purpose, he had a great plan, and he was able to manipulate the corpse tide to continuously attack the human defense line with the support of the organization behind him, as well as the earth-burrowing insects, which were summoned from other worlds. Although the combat power of the Driller is not strong, the powerful penetration ability of this creature is simply strategic, and it may have been punched a circle of holes in the entire underground of Raven City.

In any case, let's stop Yuri's plan first. Ever since discovering Yuri's drill plan and the map that only had a small piece, Xiao Yan has been hovering with indescribable uneasiness in his heart.

The dirt around them began to fall off, and the pebbles on the ground began to jump up and down.

The burrower is coming.

Xiao Yan looked up and looked ahead, and the beam of light from the searchlight was projected into the distance. Something like a subway shield swooped in this direction, layers of sharp serrations rolling, opening, and closing, like a meat grinder in a slaughterhouse.

Without Xiao Yan's order, everyone opened fire.

Xiao Yan picked up his Vulcan cannon and began to shoot, the roar drowned out all the sound in the tunnel, and the overwhelming armor-piercing bullets shattered the jagged teeth and shot into the abdominal cavity of the burrowing worm, hitting this fleshy thing to the point that the organs, intestines, and flesh were scattered like a heavenly maiden.

The fat body quickly dried up like a leaky balloon, and the stench filled the tunnel, and several soldiers vomited.

"It stinks in here. Let's get out of here. "The captain managed to keep himself from throwing up.

"Why be in such a hurry. You killed my little darling, patted your ass and wanted to leave. An eerie voice rang out from the depths of the tunnel.

"What people!" The soldiers were taken aback and raised their guns to aim, but nothing could be seen clearly in front of the pitch black.

There was a dense sound of footsteps in the depths ahead, as if dozens of pairs of feet were running.

Xiao Yan opened fire without hesitation, retreating backwards.

The bright flames of the ammunition illuminated the tunnel ahead, and dozens of four-legged beasts as strong as calves with a pair of sharp horns rushed towards Xiao Yan and the others. These creatures are covered in sturdy scale armor, and even vibrating eggs appear when a bullet hits, and a pair of sharp pincers grow from their mouths, all of which pounce wide open.

"You hit the Velocitor, dealing 22 damage, minus 40% damage reduction, and 13 actual damage."

40% Damage Reduction! The velocider in front of him is undoubtedly under the control of the contractor, and judging from the current situation, the opponent is most likely that Yuri.

These velociraptors were extremely durable, with several Vulcan Cannon armor-piercing shells ricocheting when they hit the hard skulls of their heads. The soldiers of the army also fired wildly, and the power of ordinary rifles could not even penetrate their torsos.

"Retreat! Fall back! The captain saw that the attack was extremely ineffective, and that the velociraptor was already approaching, and hurriedly beckoned the soldiers to retreat.

Like a cockroach scurrying around, the swift beast pounced in front of the soldiers in the blink of an eye. The sharp tentacles and giant pincers are extremely deadly at a glance.
