'Boom', with a loud bang, the special grenade thrown out by Fang Qingshu far away detonated in the pile of dogs, and suddenly, a large number of biochemical dogs were all blown to pieces.

Worried about being accidentally injured by the grenade, Fang Qingshu relied on the divine power in the state of the dragon body and threw the grenade extremely far, although he cleaned up most of the biochemical dogs in front of him, but the dozens of them close to him were missing. Even under the impact of the aftermath of the explosion, they rushed towards Fang Qingshu even more violently.

However, for Fang Qingshu, these were all small scenes, the shadowless flying sword flew up and down, and those biochemical dogs didn't have time to get close at all, so they were directly separated.

What followed was a rush, Fang Qingshu's eyesight was also high, as long as he saw the biochemical dogs gathering from afar, it would be directly a special grenade, and after killing most of them, he would use his flying sword to kill those fish that slipped through the net.

The strength of the biochemical dogs in this first layer was very fragile, and they had killed a lot in the battle when they were besieging Xu Zhi and them, plus the spatial mobile platforms were all paralyzed, and the biochemical beasts of the other layers could not rush over quickly, so that they were powerless to fight back under Fang Qingshu's rapid attack.

Fang Qingshu and the others were like tigers descending from the mountain, advancing rapidly in the roaring explosion. There was a distance of more than ten miles from the second arsenal to the maintenance passage, but the speed of a few people was too fast, and it took only half an hour to arrive.

However, with such an obvious breakthrough between them, their destination was already recognized by the other party early on. The biochemical dogs stationed at the entrance of the passage were densely packed with thousands. Even with the help of special grenades, it took them a lot of effort to get to the entrance.

At this time, after a burst of indiscriminate bombardment, the entrance was already a mess. There was blood and shredded flesh everywhere, and not even a complete corpse could be found. The ground was completely stained red with blood, and the strong fishy smell and the scorched smell of the charred corpse made Fang Qingshu and the others almost faint. In desperation, a few people only need to take out their gas masks and put them on, which is a little better.

"This is the maintenance lane. Helena pointed to a closed doorway.

"Open up, others cover!" Fang Qingshu immediately commanded. As he spoke, he turned around and began to kill the cyborg dogs that were following behind.

"No!" Helena tried a little, then shouted helplessly, "They shut down the energy system, I can't open this door!"

You know, Helena is actually equivalent to a super hacker, although she can crack any system, but in the face of a computer without power, she can't do anything. This metal gate weighs dozens of tons, and it can't be opened without energy!

Fang Qingshu's eyes widened, and he said angrily: "I'm coming!" As he spoke, he saw that as soon as his right hand was stretched out, a looming sword came to his hand, and as the sword leaves kept returning, the sword became bigger and bigger, and finally became a heavy-backed sword, and at the same time, the dazzling light began to condense.

"Ahh Obviously, such an opening is enough for people to pass.

But at this moment, a biochemical dog suddenly sprang out of its mouth and bit Fang Qingshu's throat fiercely. Fang Qingshu was not afraid of danger, and waved his left fist unhurriedly, smashing straight over.

The golden dragon claws and the sharp teeth of the biochemical dog collided fiercely, and only a soft sound was heard, and the head of the biochemical dog was directly beaten to pieces like a rotten watermelon. However, Fang Qingshu's dragon claws were not damaged at all, even the splashes of dog blood were blocked out by the shield formed by Fang Qingshu's scales......

Fang Qingshu took this opportunity to peek inside, obediently, it turned out that behind the gate was a downward slope, the slope was more than 100 meters long, leading to the next floor, at this time, the entire slope was densely packed with biochemical dogs, which could not be counted, and all of them were fat and strong.

"Yes, I'll give you a ride!" Fang Qingshu finished speaking, casually threw out a special grenade, and then on the side of his body, he made way of the gap, and the others also dodged away.

Then, with a loud bang, countless stumps and severed arms rushed out of the gap with a huge air current. Fang Qingshu then immediately dodged in from the gap, and found that the biochemical dogs inside had been cleaned up, this special grenade had killed at least a few hundred, but the number of people was too much, it didn't matter if a batch died, from the exit below, a large number of biochemical dogs were rushing up, the black pressed dog skin was like a sea tide, while screaming, while rushing desperately, the momentum of seeing death as home, Fang Qingshu's scalp was numb.

Fang Qingshu didn't dare to slack off, and threw a special grenade at the exit of the second floor opposite, while personally killing it to make room for the people behind.

Then, Helena and Ruoqin also walked in, and the little girl was the last one to come in after the break. In this way, there is only a crack open behind everyone, although there are still a large number of biochemical dogs on the first layer constantly rushing in from the rift, but the restricted terrain can only come in one or two at a time, and it cannot pose any threat at all.

But at this moment, the metal door that had opened the crack suddenly started on its own and slowly opened upwards. Fang Qingshu was fighting in front and didn't have the energy to pay attention here. Fortunately, Ruoqin reacted quickly and immediately shouted, "Helena, stop the gate from opening." ”

"Okay!" Helena agreed, as she raised her energy cannon, and shot at a certain place above the metal door, directly punching a hole in the metal wall, and I don't know where she hit, anyway, after a shot, the metal door really stopped, and even slowly closed again.

Ruoqin breathed a sigh of relief, casually threw a special grenade outside the rift, and then dodged the direction of the rift, and led everyone to chase after Fang Qingshu. After another loud earthquake, the biochemical dogs gathered behind the metal door were blown to pieces. By the time the next batch of biochemical dogs arrived, the time would have to be delayed a lot, and Qingshu and the others would definitely have gone away.

On the other side, under Fang Qingshu's frantic slaughter, he quickly rushed to the bottom of the slope, but at this time, there was a sudden bang from the top of the exit, and a metal gate fell, smashing heavily on the ground, and several biochemical dogs were smashed into meat sauce on the spot before they could escape.

Originally, with Fang Qingshu's strength, he could rush out before the gate fell to the ground, but considering the three girls behind him, he could only watch the gate fall. It just so happened that Helena and the others also followed at this time, Fang Qingshu smiled bitterly and said to Helena: "Let's see if it can still be opened?"

Helena went over to check it a little, and said angrily, "It's so disgusting, I just closed the door and cut off the energy." ”

Fang Qingshu had expected it, after all, this was someone's territory, and it was reasonable to be tossed by the other party like this, but he didn't like this situation, so he frowned and said: "Although I can break the door, but this two-foot-thick metal door, it's not easy for me to smash it?"

Ruoqin used a laser pistol to shoot the biochemical dog that came out of the rift, and suddenly shouted loudly, "Break the door with a fighter!"

I have to say that Ruoqin's brain is still the best, at this time, only she can think about it so thoroughly, Fang Qingshu forgot about the fighter after this tense battle.

Fang Qingshu was overjoyed when he heard this, he really woke up the person in his dream with a word, he hurriedly took out an ordinary fighter plane, and shouted: "Haha, Ruoqin is still smart, everyone come up, Helena is in charge of driving." ”

"Hehe!" the women let out a coquettish laugh, and then stepped on the fighter plane together.

There was only one seat in the cockpit of the fighter, which undoubtedly belonged to Helena, and everyone else stood in various positions of the fighter. Fang Qingshu stood at the nose, and the little girl and Ruoqin stood on the wings. At the same time, he began to control the various energy cannons above.

This ordinary fighter has four main guns, commanded by Helena, who is responsible for breaking the door, and the secondary guns on the two wings are controlled by Ruoqin and Xiao Yatou, and Fang Qingshu still uses his grenade.

After everyone had found their seats, Fang Qingshu then ordered, "Helena, first open a small hole in the door, I will give them gifts." Wait until my gift is finished and you will break the door. ”

"Understood!" Helena agreed, and immediately opened fire, only to see the front cannon flash red, and a laser shot shot at the door, almost in the blink of an eye, a hole in the door with a diameter of one foot.

Fang Qingshu didn't look at it, he directly threw a special grenade over, in fact, there was no need to look at it at all, there must be a large number of biochemical dogs behind the door. Anyway, after the grenade exploded, large strands of minced flesh and blood spurted out of the hole.

At the same time, the other three laser cannons on the fighter plane also shot a red light, cutting the metal door along the door frame, the power of the laser cannon was very amazing, and the metal door was cut off in a short time. Helena drove the fighter jet and touched it lightly, and the door fell to the other side.

The metal door weighing dozens of tons fell heavily to the ground, shaking the ground and shaking the ground, and everyone covered their ears and was dizzy.

Behind the gate, there are broken corpses on the ground, and not far away, a large number of biochemical dogs are rushing up. Helena did not dare to slack off, while directing the secondary artillery bombardment on the fighter plane, she drove the fighter plane out of the passage, and then made a slight turn to come to another metal door.
