Xiao Yuyang's injuries were not too serious, and after the team stood in place for fifteen minutes, they confirmed that he was okay and continued to search in the direction where the monsters had just come.

Suddenly white snowflakes fell from the sky, they were so light that they melted quickly when they landed on the felt hats of the soldiers.

There was very little sound from everyone along the way, except for the "pop" of boots stepping on the snow in the woods.

After marching for more than an hour, the team found a deep pit in the forest. There used to be an underground bunker here, but it was exposed due to the collapse of the ground, and it came into view.

"Is it strange that the Elbrand people are building underground fortifications at this time?" Lin Zhiwei muttered quietly.

"There is a bird for building underground fortifications on the border." The beard took his words and said, "I'm afraid that this kind of thing is not made for some ulterior purpose. ”

"Xue Tou, do you want to check it out?" Lin Zhiwei turned his head to look at his captain.

"It's coming." Xue Jinhai nodded, and the person had already walked in the direction of the cave with a gun.

The opening is formed by the collapse of the ground, so the edge of the opening is very uneven. The soldiers held their guns in their hands and followed the captain down to the pit.

The pit is relatively deep, about several meters wide in diameter, and it is completely dark except for some light at the entrance.

Some people held up their lights, others turned on their flashlights.

The slope to the pit is not too large, but there is a lot of gravel and mud on the ground, and the roots of some trees can be faintly seen on the surrounding soil walls.

"Sure enough, it's an underground fortification." After more than 10 meters into the cave, the earth wall turned into a concrete wall, and under the light, several tunnels extended to a deeper level.

"If we meet Elbrand soldiers here, will we be considered an invasion?"

"There are no Elbrand soldiers here." Xue Jinhai heard the soldier's concerns and said, "The light switch on the wall is broken, and there may be no one here for a long time." ”

"Building this kind of underground fortification is not a small project, and you don't want to come out of a hole? What a fucking extravagant thing they are! ”

The soldiers whispered, and when they came to the tunnel, they suddenly lost their minds, "Which way?" ”

Xue Jinhai shone a flashlight on the wall outside the tunnel and found several small signs on it. The words on the sign had already been covered with moss, and he used his fingers to buckle off the moss, revealing the words underneath.

"Incubation Room 2?" The border guard captain frowned, and an ominous premonition suddenly appeared in his heart.

He hesitated, but finally took the lead in the tunnel directly ahead.

"I don't like the feeling here...... one soldier lifted his boot and shook off the dirt or slime that had accidentally stuck to it. The concrete walls were wet, and an indescribable smell began to fill the tunnel.

"Stop complaining, be vigilant." Xue Jinhai said to him, and suddenly his body stopped, "Shhh, it seems that something is coming." ”

The soldiers closed their mouths, and sure enough, they heard a slight "kick" sound coming from ahead.

"Footsteps?" The question popped up in everyone's minds almost at the same time, but no one dared to be sure.

An incendiary greap shot deep into the tunnel, and moments later, a dark shadow appeared.

"Monster!" Xue Jinhai's eyes lit up, he didn't expect that his ominous premonition just now would come true so quickly.

The identity of the black shadow was clear in the light, its huge head, its monstrous mouth, and its high protruding shoulder bones...... Isn't that the kind of monster that appeared on the hill before?

A chill instantly appeared in Xue Jinhai's heart, he had already thought of something, and hurriedly shouted to the soldiers to retreat back from the tunnels and caves.

Gunfire rang out in the tunnel, and the soldiers had just retreated outside the tunnel when they suddenly heard sounds from other tunnels next to them.

"This is a monster's lair!"

No one doubted Xue Jinhai's judgment, because under the light, more and more monsters came out of the tunnel.

"Fire! Fire! The border commander's voice was a little hoarse, but he was still roaring like the weapon in his hand: "Beard, Wu Yu, Ann Bomb, don't let the monsters here have another chance to get out!" Others cover! ”

The bullets kept tilting towards the monsters that were rushing to the mouth of the tunnel, and behind the soldiers who fired, the two people named by Xue Jinhai began to find points and wiring

As soon as several of the monsters at the front fell to the ground, more monsters crawled over their corpses and continued to charge towards the soldiers outside the tunnel.

"How long?"

"One line short."

"We're about to be surrounded!"

"Right away!"

The firepower network composed of more than a dozen people has already exerted its power to the limit, and with the influence of the terrain in the tunnel, the momentum of those monsters is not as fierce as when they were near the hill before, and the efforts of Xue Jinhai and the others have bought Hu Zi and Wu Yu a little more time.

"It's loaded, Xue Tou!"

"How long does it take to explode?"

"30 seconds!"

"Withdraw, everyone get out of the cave!"

The soldiers escaped from the cave on the orders of the captain and continued to suppress the monsters preparing to rush out of the cave with fire from a safe position outside the cave.

“28，29，30。” Beard silently counted the time in his heart, and as soon as he counted to 30, there was a "boom" at the entrance of the cave, and a fire rose into the sky.

"Blow up you bastard!"

Dust fell from the entrance of the cave, and the explosion caused the rubble and dirt above it to fall, resealing the place.

"The entrance to the cave is sealed!" Wu Yu's face showed an excited smile.

"Whew~" Xue Jinhai's heart breathed a sigh of relief. Not a single monster escaped from sight.

"Lin Zhiwei, use the radio to contact the regiment headquarters and report the coordinates and situation here......"

"Team...... Captain! ”

Before Xue Jinhai's order was finished, a soldier next to him suddenly pointed to the position behind the cave and exclaimed: "It's collapsed again!" ”

"Oops!" Xue Jinhai was shocked when he heard this, and secretly said that it was not good, "Retreat, retreat to the woods." ”

Lin Zhiwei had already taken the radio off his back and held it in his arms, and the sudden retreat order made his hands and feet mess up, and the gun hanging on his arm fell to the ground.

"Go to the woods, quick." Xue Jinhai helped him pick up the gun and pushed him again.

The previous hole was sealed, but what everyone didn't expect was that the explosion caused the rest of the underground fortification to begin to collapse and leak out.

In the midst of the dirt, hideous figures sprung up like mushrooms after a rain, and their gaze at the soldiers made people shudder.

"Oh my God! How can there be so many monsters! ”

At the exclamation of one of the soldiers, the monsters began to charge, and they poured like a tidal wave towards the dozen or so warriors.
