Xia Fei Yun's method of gathering breath quietly rises and pursues the attacking team.

There are many unknown buildings and pipelines on both sides of the spiral main road, which is very messy. Xiafei relies on these buildings as a cover and soon catches up with them.

The area of owl base is not small. In addition, the soldiers with scars all the way tried to block the advance of large forces, so the speed of attack was not fast. At this time, it was more than ten minutes before the United forces landed at the dock, and the large forces had just advanced to the base. Xiafei had the method of restraint for protection, so his whereabouts did not attract this person's attention.

"It's better to find other ways to enter the command center. This road is too obvious. If you rush in from here, you will be found." Xia Fei thought.

On the right side of the wall, there are many pipes leading to the top floor. There are various pipelines, such as circuit pipes, air circulation pipes, water pipes, and various pipes. After all, the base is a whole, and water and electricity and other things need to be piped to all corners of the base.

Xia Fei wanted to get close to the pipes and found a black alloy pipe enough to hold his body. He cut a round entrance on it with the light chasing.

The sharp pursuit of light, just like a laser, can easily cut the metal tube wall with a thickness of 1.5cm without making any sound.

The pipe is empty. Xia Fei puts the cut steel plate gently on the ground, shrinks into the pipe and climbs up quickly with both arms supporting both sides.

This kind of ultramicro computer uses a kind of composite high-energy polymer battery. Under normal circumstances, one battery can support the microcomputer to run for 1000 years without replacement, which is very convenient.

Although the light is small, the brightness is very sufficient, and the visibility is more than 20 meters.

It seems that the pipeline has been abandoned for many years. There is a rotten smell everywhere, and the air is also turbid. Fortunately, the oxygen in the pipeline is enough to support life. Xia feiqiang resists this suffocating smell and quickly walks through it.

Passing through a narrow place is the most important test of a person's flexibility. Xia Fei uses a posture that is very similar to breaststroke. Her legs pedal on the inner wall of the pipe to provide enough propulsion for the body. Her arms and legs work together, and the movement is slight but not slow.

In a flash, Xiafei has already entered the top layer of the base. The pipeline turns a bend and turns into a parallel state. There is a three fork in front of it, leading to three directions respectively.

Xia Fei opened a small hole on the wall of the pipe that could only hold one eye with the light tracing, and observed the situation outside before pasting it.

This pipe is set up close to the ceiling. Xiafei is standing at a height of more than ten meters and looking down, the outside situation can be seen clearly.

The top floor of the owl base is a place similar to a square, with an area of about four or five football fields. The entrance is just in the center of the square, surrounded by rooms next to each other. They are like walls that surround the square. Xia Fei estimates that these rooms should be connected in series, and it is easy to enter the next room from one room One room.

Four scar's men were waiting in two hidden corners outside the square. They were lying on the ground with a kind of high-power laser gun in their hands. If anyone came up from the entrance, they would be warmly welcomed by the laser gun.

One of the shooters licked his lips with his tongue. His eyes were fixed on the only entrance through the sight glass. His body was still. The distance between his fingers and the trigger was always 0.5cm. It was like a stone in the shape of a human being, a stone that could breathe.

Obviously, all four are experienced snipers with regular military training.

In fact, at Xiafei's speed, you don't have to be afraid of these guns. After all, it takes time to aim and pull the trigger. Their neural reactions may not be able to keep up with Xia Fei's speed of more than 800 meters per second. However, if they take risks, they will inevitably startle the snake, and the effect is not as secret as this.

"Eh?" Xia Fei suddenly found that the rooms around the square had been sealed with heavy alloy plates. It seemed that there were still some movable shooting holes left on them. These round shooting holes were blocked with alloy plates from the back. Once someone intruded into the scar, the person could quickly open these holes and stretch out weapons to shoot at the square.

This shows that scar had been prepared for the invasion of the joint forces, otherwise it would not have been possible to lay out heavy defenses in such a short period of time.

It can be imagined that if the joint forces enter the square without knowing it, they will immediately become live targets and be severely damaged by people hiding in the room.

"Ha ha, professional soldiers, snipers, things are really more and more interesting." Xia Fei takes back his eyes and whispers to himself.

"What's interesting?" The ghost sat cross legged not far from Xiafei and asked, he is a ghost. The bad air quality here is not a problem for him at all.

"I'll tell you later that I need to further verify my conjecture." Xia Fei said with a smile.

"Mysterious, pretentious." Ghost shadow white Xia Fei one eye, discontented whispered.

Xia Fei thought for a few seconds and decided to follow the right passage, which led directly to the rooms around the square.Xia Fei changed her posture, knelt down on her knees and crawled in the pipe. The two arms move alternately in front of the body, and the distance between each movement is just 0.4 meters, which is not too much or too many. It is impossible to see the outside inside the pipe. Xia Fei has to rely on his own measurement to speculate on his position.

After 439 steps, Xia Fei again opened a small hole in the pipe with the pursuit light. If his calculation is correct, this should be the first room on the right.

As Xia Fei expected, the room is about 150 square meters. The light is as dark as dusk. There are six people in the room. They are sitting around a very solid round table, doing the same thing, cleaning their guns.

Each of the six men had a dark laser rifle, which was a little smaller than that of the four men who had been waiting in the square. They carefully wiped every part of the laser gun with cotton cloth. After repeated wiping, they seemed very careful.

There is also a communicator and dozens of cylindrical energy cartridges on the table. One cartridge is enough to sustain a laser gun to attack for more than 10 minutes. If all these clips are destroyed, not to mention 8000 people, there will not be many left in an integrated Army division.

"These people seem to have been prepared. It is possible that each of these rooms has several soldiers ready to ambush. What should we do now?" Asked the ghost in a deep voice.

"You'll have to kill half as much as you can." I thought about it and said.

"Why half?"

Xia Fei smile, very insidious said: "kill both sides will lose balance, and I hope to see the scene of both sides lose." (to be continued, please visit www.qidian.com , more chapters, support authors, support legitimate reading! )
