After eliminating the enemy in his sight, Ye Han was not in a hurry to expand the results of the battle, and the four teams stood still for the time being, relying on insect drones to reconnoiter the situation on the top floor.

The drone that flew into the corridor immediately dispersed, flew in different directions, met a room along the way, flew into a drone, and flew out immediately if the enemy was found, if the enemy was found, immediately find a hidden but easy to observe place to hide, as far as possible to hide and not move, so as not to attract the attention of the insects.

In this way, Ye Han quickly figured out the situation on the top floor, Ye Han gave an order, and four groups of people entered the corridor at the same time, four people to the left, four people to the right, no one's room directly skimmed, the room with the enemy first threw a flashbang, and then rushed in to quickly kill the enemy.

In the blink of an eye, the group led by Ye Han had emptied more than a dozen rooms.

At this time, the insect drone found that the insect people in the first few rooms were ready for battle, just waiting for Ye Han and others to send them to the door.

Indoor close-quarters combat is one of the most dangerous ways to fight, and it is possible to take advantage of the fact that there are only eight people attacking at the moment, and if the enemy is well prepared, continuing to attack from the corridor will not only fail to achieve good combat results, but may also lead to casualties on your own side.

However, the special service team was ready to land in the air, Ye Han gave an order, eight people left the corridor and entered the room, two people rushed to the wall, one person pasted plastic explosives on the wall, and the other person took out a flashbang, opened the safety ring and prepared to drop the bomb, and nodded at his comrades.

The soldier in charge of the blast immediately gave a detonation signal, and with a loud bang, the explosives left a hole the size of a basin in the wall, and before the smoke and dust cleared, the soldier in charge of the bomb had already thrown the flashbang into the next door.

The classic combination of flash and loud noise paralyzed the bugmen next door, and the warriors immediately shoved their guns into the hole and opened fire to kill the bugmen next door.

Blowing up the wall is a very effective offensive tactic, very suitable for street fighting and indoor combat, but it is not a new tactic, as early as the forties of the last century, the 17th Division of the 6th Column of the East Field is best at scanning all obstacles with the blasting method in the battle, and the combat characteristics are that they never go through the streets, and they all rely on explosives to penetrate the wall and make holes, which is called the tiger.

Although that was nearly a century ago, the military has never lost its traditions...... The special service team is equipped with the most advanced power armor of human beings, and even if it is difficult to fight the insects, it is no problem, but every member of the special service team instinctively avoids fighting with the enemy, and they all hollow out their minds and work a clever word.

It's not the first time that the insects have fought an indoor war with humans, but they really haven't encountered a wall-piercing style of fighting, and they have been attacked by the special service team in a row, and the insects killed are not a hundred but eighty!

Bugmen are not stupid at all, they are originally humans, even if they are controlled by aliens, but the original way of thinking is still there, after figuring out the combat methods of the special service group, the insects made corresponding arrangements as soon as possible, and even wanted to attack the shield with their spears, intending to ambush the special service group with wall-piercing tactics.

The Wormman's abacus is indeed a good game, if Ye Han and the others don't know the situation of the Wormman, maybe they will really step into the trap.

It's a pity that the insects didn't expect that their every move was transmitted to the secret service team by the drone's footage.

Ye Han simply made a plan, and after entering the next room, everyone squatted in a safe corner and waited.

After a while, a flash of light pierced the wall...... The worm man has no explosives, so he can only use mercerized light to chisel the wall, to be honest, the effect is really not very good, the soldiers see the mercerized light, can they still not know where the worm is?

At this time, the fighter in charge of throwing the bomb had already held the flashbang in his hand, and the moment the wall was pierced, he immediately threw the flashbang into the hole, waited for the flashbang to explode, and then shot at the next door.

Ye Han gave a thumbs up to the insect man in his heart, if he wasn't fighting with the insect man, he would have to praise two sentences: the insect people are all good people, and even the holes in the wall have been built for us, how much explosives do we have to save......

I don't know if the insect man will be so angry that he will vomit three liters of blood after knowing Ye Han's heart.

Finding that the wall-piercing tactics could not be replicated, the insects were also ruthless, and directly rushed into the corridor in a group, intending to crush the special service team with numbers.

The question is the Secret Service even this? A few flashbangs were thrown, and the bull sent the three-barreled machine gun out of the door, pressed it to the ground, and pressed the fire button.

The furious rain of bullets swept through the corridor like a scythe, and the swarms of insects fell like scythes harvesting crops.

In just a dozen seconds, the corridor was already full of insect corpses.

The remaining Zerg did not flinch from the death of their companions, and still rushed into the corridor without fear, and finally all died at gunpoint.

The strong counterattack of the insect man completed the special service team, causing Ye Han and the others to empty the top floor as quickly as possible, which was not known how many times faster than everyone fighting from room to room.

The loss of the top floor made the insects very angry, and the insects on the third floor gathered as fast as they could, holding the staircase and the elevator to the death.

The faithful drone sent this scene into Ye Han's eyes, Ye Han rolled his eyes, and simply ordered the servants outside to enter the building from the top floor.

Although the servants are tall, the ceiling of the laboratory is not low, and the servants can move freely in the laboratory with their heads held high.

The feint servants immediately split into a part and flew into the top floor with their wings.

According to the distribution of the insects on the third floor, Ye Han arranged the servants to the corresponding positions, and then placed the explosives in the appropriate positions, and after everything was ready, all the explosives were detonated at the same time, and the floor slabs on the top floor were instantly blown through.

The servants immediately rushed over, first throwing flashbangs, and then sweeping wildly with their rifles, and the unprepared insect men were immediately killed and wounded, and in the blink of an eye, they were all dead.

Ye Han didn't know what to say, the speed of cleaning up the third layer was faster than cleaning the top layer, who did he ask to reason?

The advanced experience of cleaning up the two floors in a row must be maintained, and the special service team and servants continued to march to the second floor under the command of Ye Han.

The area of the second layer is three times larger than that of the third layer, and the difficulty of clearing the nest is much greater than that of the first two layers, but the number of insect people is not more than the first two layers.

The battle continued, the insect drone flew into the negative layer, and Ye Han unexpectedly found that there was not a single insect person on the negative layer!

Continuing to reconnoiter the negative second floor, again nothing was found.

Could it be that the worms knew that they were not opponents, so they all ran away in advance?

At this time, the drone found a hole in the corner of the negative second floor, and there were no insects and no captured people, and the situation was already very obvious.

The hive immediately asked: "Captain, are you chasing?" ”
