The monkey slowly lay on the ground, moved forward more than 30 meters a little, then took out a grenade, pulled the safety open, waited for two seconds, threw the grenade directly into the tunnel, and quickly retreated.

After a grenade explosion sounded, the assassin in front rushed out without hesitation, and the government soldiers who were shooting at the assassin and others in the tunnel were killed by the grenade, and the assassin and the others rushed out without hesitation and continued to walk forward.

The Yu reinforcements behind him followed the gunfire and walked forward quickly, ready to follow the butts of these mercenaries to check the cheap, but before they took a few steps, they saw two government soldiers holding weapons in the corner tunnel, rushing in the same direction, and one of them seemed to feel something, turned his head to look at Yu Yuanjun, the two looked at each other for two seconds, Yu Yuanjun took the first step to shoot, killing the two government soldiers.

After the shooting, the remaining reinforcements did not panic in the slightest, nor did they feel uncomfortable after the first killing, but walked to the two corpses, picked up the magazines and grenades on their bodies, and continued to walk forward.

"Head, there is gunfire behind you, the enemy of AK, the distance is probably less than a hundred meters, I don't know what to hit again? Do we have any allies behind us? ”

Drew was in charge of the rear of the hall, the gunfire was a little distance, if it was an enemy, it must be a friendly attacker, but when he acted, no one told them that there was still a group of people behind him.

"Pay attention to the back, it's better to have reinforcements than no reinforcements, whether it's reinforcements or not, the enemy's enemy is a friend!"

After the bald head finished speaking, he took a brisk step forward and jumped out of the tunnel directly, three government troops were rushing over, shooting and killing the three people, and quickly jumped back into the tunnel, there were more than a dozen bullets in the previous position, and above a building in the distance, a machine gun was already aimed at the direction of the bald head.

"Two and a half o'clock, a machine gun, knock him out!"

As soon as the bald voice fell, a grenade rolled into the tunnel, and the bald head immediately grabbed the grenade and threw it directly out of the tunnel.

"Something is wrong, the combat effectiveness of these government troops is not weak, there is a problem with our intelligence, there are elite units of the government army on the top of this mountain!"

The bald head walked forward for a distance, and immediately felt that something was wrong, before killing those soldiers, there was no sense of vigilance at all, in a word, the peasants with weapons, without the slightest combat effectiveness, were crushed with one blow.

But the soldiers I meet now, whether it is marksmanship or small-scale cooperation, are not the same level as the previous soldiers, at least they have a certain combat effectiveness, and they are all soldiers who have been on the battlefield and seen blood.

"Head, why don't we withdraw?"

After thinking for a while, Drew looked at the bald head, it is no longer a problem with terrain intelligence, even the enemies they need to face now are different, fighting miscellaneous soldiers, one dozen ten, twenty is fine, but facing elite troops, not to mention one dozen ten, even one dozen five is impossible, or even one dozen three is impossible.

"Well, let's get out!"

The bald head frowned and looked ahead, now they have been suppressed in this part of the tunnel within about thirty meters and cannot move, especially the machine guns at the height, which makes them have to move slowly along the left wall of the tunnel, if they wait for the government army to surround them, they will not have time to retreat.

"Assassin, monkey, retreat, Drew, you get out of the way, the rest follow me!" The bald head gave the order decisively, and the seven people quickly turned around and moved back quickly along the way they came.

However, at this time, the government troops, in addition to the people who were shooting at the front, had already begun to circle around the rear, and some people surrounded along the flanks.

In the underground command room of the government army on the top of the mountain, a mercenary team of about ten people sat in the command room, crossed Erlang's legs, smoked cigarettes, and chatted with each other.

"It should be the people of the war squad above, do you want to deal with them!" The leader of the mercenary squad, a man with a long scar on his face, plays with a dagger in his hand.

"Captain, this is not our task, our task is to train this group of people, the rest of the things have nothing to do with us, even if we kill the people of the war team, we won't give me a penny more, I think it's very good here, it's very comfortable, to be honest, if every mission is so easy, I think I'll be happy!"

"Whatever you want, if you don't go, I'll go play with them!" After the man with the scar on his face finished speaking, he picked up his M16, put on body armor, slowly walked out of the tunnel, opened the weapon safe, and his face flashed away.

"The gunfire is getting more and more intense?"

Yu Reinforcements walked halfway, and suddenly felt that the gunfire in front of him was getting denser and denser, and he couldn't help but stop, slowly stretched out his head, and saw about two meters away, on the top floor of a three-story building, a machine gun position made of sandbags, on which there were two government soldiers, who were facing their own ten o'clock direction of fire suppression, which should be the position of the mercenary team.

The remaining reinforcements cautiously leaned out half of their bodies, aimed their weapons at the target's position, and used the machine to aim at the AK to hit a target close to two hundred meters away, and they were hiding behind the sandbag, only half of their body was exposed, which was a challenge for any gunman.

Moved the crosshair to the machine gunner's head, and was just about to pull the trigger, Yu Yuan turned the muzzle of the gun slightly, and fired a shot at the window of the three-story building, the bullet missed about three or four meters, squatted down without hesitation, silently calculated the position of his shooting and the position of the bullet landing, and roughly knew where the problem was, and after silently adjusting it, he once again aimed at the head of the machine gunner on the third floor, but this time, The deviation between the crosshair and the target to the right is about a centimeter or so.

Gently pulling the trigger, after the remaining reinforcements finished shooting, they continued to observe the target, but did not hit the target, but it had already hit the sandbag, and once again adjusted the direction according to the bullet landing point, and pulled the trigger for the third time.

This time, the bullet, as expected by the remaining reinforcements, instantly crossed a distance of two hundred meters, hit the little green hat on the top of the machine gunner's head, and fell to the ground.

"The gunfire has stopped, back off!"

When the bald head and the others retreated along the left side of the tunnel, the bullet that had been shooting not far from them suddenly stopped, and immediately accelerated and retreated.
