A loud rumbling sound resounded through the space, and six figures swam underwater, only to reunite on the shore of the underground waterway a few minutes later.

At this time, it showed the extraordinaryness of Zhang Zhi's armor, and when he stood there, others didn't feel his presence at all.

"It's about two kilometres up the sewer, but it's the rainy season, and the sewer is too full, and in some places the water level is too high, so we need to swim through, and of course, it's not difficult for us."

Cao Yanan pointed to the direction of the upper reaches of the underground waterway and said.

"All after me!"

Zhang Zhi's voice came, and then everyone followed the sound of his footsteps to move forward, and after walking less than a few dozen meters, they found that there was no river bank in the next section, and they could only swim through the water.

Zhang Zhi went into the water in an uproar, and the others also swam forward, just walking and swimming, and suddenly, Zhang Zhi's voice came from the front.

"Everyone, be careful, here's a hole, it should be an underground drainage pipe, do we climb up along this pipe and get to our destination?"

Cao Yanan walked up and looked at the pipe, which was only about one meter in diameter, and when she looked up, it was also pitch black.

"This is here, I came down from here at the time, this pipe is one meter in diameter, we can climb up with both hands, but there is a stainless steel cover net on it, I directly pried open the net cover last time to enter this pipeline, I don't know if it is sealed now."

"It doesn't matter if he's sealed or not, if he finds a place, just kill him."

Zhang Zhi's words were full of local tyrant atmosphere, which made Li Qingfeng and others have some thoughts, and secretly said that such a reckless person, I don't know how the military region looks at it, let such a person be the captain.

But Zhang Zhi said that he had already begun to climb up, and everyone had to follow.

This pipeline is not short, two or three hundred meters long, and it is still dark on it, but Zhang Zhi stopped at this time, and it was over.

It is not the net cover that Cao Yanan said, it is a solid stainless steel cover, no wonder there is no light at all.

He didn't know how thick the lid was, so he wanted to knock on it and try it, but he was afraid of startling the snake, so he leaned his head up and put his ears on the lid to hear about it.

As soon as he put his ears on, he heard a lot of chaotic sound waves, and after filtering out the rumbling of the water, he finally made out something, and there was even the sound of footsteps.

"According to the sonic analysis on the opposite side, this steel cover should be fifteen centimeters thick, but I can blast his lock open at once with all my strength, are you ready to rush out?"

"Not yet, Master Xuanbei is still a little below, wait a minute!" Cao Yanan said.

"Alright, you're all set!"

Soon, Xuan Bei's voice also came.

"Good! I counted down to three, and after popping the lid open, everyone rushed up! ”

Saying that, Zhang Zhi has begun to count down.

“3、2、1！ Boom! ”

Zhang Zhi relied on armor and gloves, he was not afraid of hurting his hands at all, and without launching the iron body skill, he punched out with all his strength, and the power of this punch was almost a god blocking and killing gods.

The lock of the steel cover broke directly, and the lid flew in response, and then a clangling sound was heard in the distance.

Zhang Zhi jumped out of the hole, finally having a down-to-earth feeling, but the others jumped out of the hole like groundhogs, and they all felt that they were breathing fresh air.

"Wow wow wow wow ......"

Sirens sounded all over the world, and the walls flashed with alternating red and blue lights, and everyone was still not used to it, and after a few seconds, they realized that it was the end of a corridor.

Hurried footsteps sounded in some places, and Zhang Zhi said in a deep voice: "Prepare for battle!" ”

Seven or eight people ran up to them, all with strange guns, and when they saw a few, they shouted, "Who's there?"

Zhang Zhi didn't care what kind of bird language they were, although he knew who was there, but he stabbed with his sword, and red light flashed over, and it turned out to be all laser guns.

However, the laser shot at Zhang Zhi's body, and there was no reaction at all, Zhang Zhi pounced, pierced two with a sword, and smashed a person with a punch and a helmet head directly flattened.

Cao Yanan directly used the three-edged thorn, this three-edged thorn was extremely fierce, a knife pierced a person's right chest, and the blood spurted out along the three blood grooves of the three-edged thorn, spraying her all over.

Yu Wenhao used a military shovel, this military shovel has three sections, at this time he stretched out, also more than a meter long, the laser gun shot at the shovel, but there was no response, but he directly shoveled down a person's head.

The two Taoist priests used a three-foot long sword, which was one of their advances for this mission, of course it would not be weak, the two of them solved one person by themselves, only the monk Xuanbei, standing behind before he could make a move, the enemy was all gone.

Zhang Zhi raised his foot and kicked one head up, and the other head flew to the corner of the wall, directly smashing the camera.

"Lieutenant Colonel Cao, how to go, listen to you now, I am only responsible for the combat command!" Zhang Zhi handed over the task of leading the way to Cao Yanan.

"This is the lowest floor of District 51, we have to go to the general control room, get the upper floor, and the important information is on the upper floor. To get to the upper floor, we have to go through a fire escape. ”

"Where do we need a fire ladder, we just blast the concrete layer overhead, don't we go directly to the upper floor?" Yu Wenhao said.

"Hehe, you try, see if you can blast it away. The layer we are on now is actually a protective layer built under the wreckage of the spaceship, and it is all the wreckage of the spaceship. The fire ladder is built in the very center of the ship, which means that from there, we go up to the inside of the ship's wreckage. ”

Cao Yanan ignored the shocked crowd at all, and walked directly to the front, she was familiar with the way, turned to a door, there were more than a dozen people there, six people rushed up and slashed and killed, and soon all of them were killed.

"Why are these people so weak? How do I feel that they are less than ten o'clock in their physical strength? Zhang Zhi was a little puzzled.

"I don't know about this, maybe they are the guards in charge of the bottom, who would have thought that at this time, there would be people coming from the ground, and now the whole world is unable to protect itself, where is there anyone doing such a thing as us."

Cao Yanan said, flipped out a card on the corpse, and swiped it next to the door, and the door automatically retreated to both sides.

"Go, go!"

Zhang Zhi was the first to rush in, but before his foot stepped on the stairs, a fist rapidly enlarged in front of his eyes, and he turned his head away, narrowly avoiding the punch.

As soon as he dodged his fist, a thick leg swept across his feet, and this time he couldn't dodge, so he had to raise his foot and kick the man's calf.

"Boom!"

The strong concussion caused the two of them to retreat, and both of them were shocked in their hearts, because both sides were wearing armor, and although the styles were different, they were definitely the same material.

Cao Yanan and the others in the back were also attacked, there was more than one opponent, Yu Wenhao was knocked away by another armored man with a shield in one face, fortunately he had rough skin and thick flesh, but there were also faint bloodshots at the corners of his mouth.

Cao Yanan's triangular stab pierced a person's throat, but he also received a few shots, and the bullet hole in his shoulder seemed to be still smoking, which was a laser gun burn.

The stairwell is actually not big, and there are more than 20 people on the other side. Zhang Zhi saw that there were two people wearing armor, and in addition to the person who was fighting against him, there was another person who was chasing Yu Wenhao and beating him directly to the door at the bottom. Yu Wenhao barely had the strength to fight back, but fortunately Xuan Bei caught up at this time and helped him attract a little firepower, but the two were quickly knocked away.
