Looking at the ground beast crawling rapidly from the ground, walls, and overhead, as light and swift as a lizard, Gao Shan turned back with a twinkle in his eyes, "You all go back first, and then you don't have to come in again." ”

He Qiu was about to ask 'why,' when he saw Gao Shan's shoulders short, and his sturdy body rose into the air, swept over the heads of the soldiers in the front row, and landed firmly beside Shangguan Ergou.

"What are you doing here?" Shangguan Ergou mentioned in his heart, and his hand on the handle of the knife on his waist trembled instinctively, and he stopped again when he saw that it was Gao Shan.

"Come and help!" Gao Shan looked ahead with a torch in front of him, reaching out to open the medicine box.

Then I saw the four wooden boxes of different colors in the medicine box 'snap' open, and the four-colored silk threads flew out.

A graceful and illusory picture scroll appeared in the corridor ahead, and the four-colored silk threads were intertwined and overlapped with each other, surrounding the vertical and longitudinal staggering, blocking the advancing earth beasts.

An earth beast leaped from the ground and swooped forward, a hair-thin red light piercing forward and piercing into its eyebrows.

Then, with the red dot as the center, a cylindrical flame suddenly splattered out, and the red dot the size of a needle tip immediately turned into a hole the thickness of a wrist, and there was a faint heat inside.

You can smell the smell of barbecue in the air, and the aroma is so fragrant that it makes people feel a little appetizing.

The soldiers, who were still facing death, looked at each other and stood up to put away their guns, but they didn't know whether to do it or not.

Looking at the earth beasts rushing in front of them, they all looked like earth beasts that had been pierced by a 'torch' and turned into lotus roots, and suddenly felt that there seemed to be nothing wrong with them here.

"How long can you last?" The only one who remained calm was Shangguan Ergou, seeing the fine sweat on Gao Shan's forehead, he knew that he was not as relaxed as he seemed at the moment.

"Half an hour is fine!" Gao Shan replied in the affirmative, and walked forward.

The closer they are to the spirit needle, the less True Qi will be consumed, and the more they will be, and their task is to find the lair of the Earth Beasts, not to stand here and wait for them to die.

Judging from the few encounters with the earth beasts, these monsters are like endless, trying to kill them all while standing, but no one has done it yet.

"Everyone put away their guns, keep up lightly, look for opportunities to recover their strength, check the ammunition reserves logistically, and let the top send new ones down if they are not enough, you have 20 minutes. ”

Shangguan Ergou shortened the time by 8 minutes, and it had already used up 2 minutes just now, and these 8 minutes were left by him to Gao Shan to save his strength.

He is a martial artist himself, and it is still very clear what the consequences will be if his true qi is exhausted.

In the army, they are still accustomed to using martial artists to refer to people with extraordinary strength, and what transcendent people don't sound like oriental charm, gay in gay.

Gao Shan stopped the earth beast in front of him with the power of one person, whether it was the ground beast rushing from the ground, the wall or the overhead, it could not escape the fate of being 'colluded'.

In five minutes, the team advanced 800 meters, a speed that once again shocked everyone.

In 10 minutes, the team advanced to 2,000 meters, and as the fighters recovered physically and mentally, the speed of the advance also increased.

15 minutes ......

After 20 minutes, the team had advanced about 4,500 meters, and Takayama's clothes were soaked with sweat.

"I can't hold it anymore. Gao Shan gritted his teeth and said.

"Form a battle formation, prepare..."At the moment when the silk thread in front of him flew back upside down, Shangguan Ergou waved his hand and shouted: "Fire." ”

Da Da Da ......

The gunshot rang out, Gao Shan also withdrew the spirit needle and sat on the ground, Shangguan Ergou squatted down and looked ahead on guard and asked, "How is it?"

"The spirit of manipulation is very mentally draining, and this head is about to explode!" Gao Shan just sat on the ground, rubbing his temples with his thumb.

"We'll take care of the rest, you rest first. Shangguan Ergou stood up after speaking, and continued to direct the team to move forward.

The two teams of soldiers alternated to form a network of fire, and a total of 20 squads followed behind them, one every 20 meters, ready to take over the comrades in front.

In the time that the mountains bought them, there were enough troops on the surface, as well as all kinds of ammunition, equipment, and resources.

These ammunition are not ordinary ammunition, including the armor-piercing bullets used before, and ordinary bullets hit the ground beast, which is difficult to cause damage.

The team is also equipped with a large number of expensive armor-piercing high-explosive shells, which are to deal with the crisis or high-level monsters that may arise.

No one can prove that there is only one kind of earth beast, and perhaps they also have their own civilization and level, but they have not yet been discovered by humans.

After all, before this operation, the humans were only passive defenses, trying to trap them underground.

But now it seems that this approach is undoubtedly wrong, and if it is left unchecked, who knows how many underground spaces will be built underground.

Because of this, coupled with some of the above speculations and information from the earth beasts, as well as the many reasons why this sinkhole happened to appear in the city, this extremely dangerous and difficult assault mission came together.

"Machine gun group, up!" The soldiers in the front row retreated to reload their ammunition, and the squad leader in the rear immediately waved his hand, and six soldiers carried three heavy machine guns and rushed forward.

"Fire suppression!" The front row prostrates, the back row gets down on one knee, and then there are soldiers behind who buckle something like shoulder armor on the shoulders of comrades who are kneeling on one knee.

Three machine guns were mounted on the 'shoulder armor', and a soldier also knelt down on one knee in the middle of the machine gun, and the soldier standing at the end pulled the trigger.

Buzzing......

The bullet chain was driven, and the empty bullet casings fell to the ground like a torrential rain, and the metal hit made a 'ping-pong' sound between the collisions.

As far as the eye could see, all the eyes in front of them turned into bullet fishing nets, and plasma, severed limbs, and stumps flew everywhere, and the ground beasts were cleaned up on the spot.

As a battlefield killer, the heavy machine gun that exists in the meat grinder bursts out with its powerful lethality at this moment.

The prostrate soldier in front of him retreated against the wall, kneeling on one knee to support the front barrel and the soldier in the middle to lift his leg and move forward in a half-squat position.

Crushed by the heavy machine guns, the team's speed was once again happy.

In 2 minutes, the soldier with the pistol could not bear the weight of the barrel and the tremor when fired, and a new soldier was on top of it.

Within seconds of stopping shooting, new earth beasts poured out of the cleared alley.

These damn monsters are like cockroaches with extreme fecundity and vitality, and they can't be killed no matter how much they kill.

The corridor had become slippery and muddy to the slaughterhouse, and every step felt like it was going to slip or fall into the mud and couldn't pull your legs.

When the team reached the end again, threw six grenades in succession to clear the left Yongdao crossing, and turned to the left, the destination of their trip was reached.

An underground space that looks like it has just fallen comes into view, less than 100 meters in front of the road.

But what was covered in it made the fighters shudder.
