No matter how slow the sun sets, there will always be a time to set, and it's winter, so it's even shorter.

As night fell, there was already silence on the side of the Beilian base.

These days, in order to prevent the plan to sneak out of the house today from being discovered, Xia began to control the lights in the Beilian base in a planned way a few days ago.

Although it is not completely turned off, or it is easier for the people on the side of Blue River City to guess the intention, the lights that can reach the doorway and outside the walls of the base have been turned off.

From a distance, the base of Beilian looks like a candlestick, the kind that is dark under the lamp.

The 300-strong troops quietly left the base from the opposite side of the North Union and the Blue River, and the civilian personnel who had been ready to take over the post immediately filled their positions at this time.

After the previous incident of the Radiation Beast Swarm, the civil department has become proficient in this kind of thing.

After a silent march throughout, the large army arrived at the agreed place, which was a huge building three kilometers away from Blue River City, where as long as you didn't shoot, you didn't have to worry about being discovered by the people of Blue River City.

So Xia looked at the time, and it was almost time for him and the origin to agree.

Looking out of the window of the building, Soxia saw a ray of light coming from a distance.

This ray of light was very familiar to Xia Xia, it was shining from the emitter on the Origin Head.

He took out the prepared flashlight and flashed it in the direction of the beam a few times, and the beam on that side also flashed a few times to indicate that he noticed the other party.

Not long after, Origin took his mechanical warriors to the downstairs of Gu Xia's side.

"Soxia, I'm here."

The origin of the weapons and ammunition appeared from the staircase, and after a long absence, he heard the voice of the origin again, so Xia suddenly felt a lot more relieved.

You must know that in these few days when there is no origin, Gu Xia is full of worries about his life.

If it weren't for the necessity of this operation, Xia would not have been able to send the Origin out for that long.

And he didn't even have a robot guard left by his side, which was completely inconsistent with Gu Xia's fear of death...... Ahem, cautious character.

"It's been a long time, how's your situation over there?"

Some misty voices came from under Gu Xia's mask, and sometimes Gu Xia really envied them, at least they didn't have to carry this troublesome mask when they went out.

"It's not bad, we have replenished a group of fighters, the number has reached one hundred and twenty people, and the weapons and equipment have also been replenished once, and currently have ninety machine guns, one hundred and twenty automatic rifles, all of which have been equipped with grenade launchers, as well as various types of auxiliary equipment."

"There are still some surplus weapons in the replenishment, which I did not bring. There are also some special weapons that you can check out when the time comes. ”

The origin roughly explained the harvest to Gu Xia, of course, only Gu Xia can understand the deep meaning, and of course others think that these are all sent by the mobile city behind Gu Xia.

"Okay, I know, then you and Ning Mu will command the troops together."

Although I am very interested in the special weapon that Origin said, this situation is obviously not the time to speak, so it is better to wait until the battle is over and talk to Origin in detail.

"Shhh...... I really didn't expect that the robot you said seemed to be a little outrageous in intelligence. ”

Ning Mu, who was watching this scene, was a little surprised and let out his feelings.

"Of course, Origin is no ordinary robot." Hearing that someone was stunned by the origin, as a person who regarded the origin as a friend, Xia was naturally very happy to hear the praise of him.

Ning Mu nodded and said, "Let's not talk about this for now, let's plan the next battle first." ”

Soon, Origin and Ning Mu got together and began to discuss the specific battle plan for the next step.

Half an hour later, the two returned to their respective units and began to lead the warriors towards Blue River City.

Night is the best protective color, not only because of the effect on shooting at night, but also because many people are already asleep at this time.

And there is another advantage of night for the Northern Alliance, that is, at this time, even if it is discovered, those cannons in the Blue River City cannot get the best shooting guidance due to the influence of the observation field of view, and the threat to the soldiers of the Northern Alliance is reduced a lot.

Although, if this plan succeeds, the enemy may not have time to use artillery.

Quietly touched the underside of the chassis of the mobile city, where there was a gap between the rows of tracks that was large enough to pass through several people.

It's just that the purpose of Beilian this time is not here, but a small opening in the chassis of Blue River City.

According to the information brought by Ning Mu, under the chassis of Blue River City, there is a small door, and there is a passage inside that leads to a secret warehouse.

And it's a warehouse leading to the inner city of Blue River, where almost no one walks through and is unguarded, and it's the best place to sneak into battle.

After a while, Ning Mu, who was looking for the small door according to his memory, found that place.

Then the robot unit leapt forward and burrowed into the small door as a vanguard.

So Xia stared at the robot troops that slowly entered the passage and gradually disappeared, waiting for news from them.

I don't know how long it took, if it weren't for the fact that there were no gunshots, so when Xia Du thought something was wrong, the communicator in his hand suddenly flashed a few green lights, which was a sign of successful infiltration.

Gu Xia and Ning Mu looked at each other and nodded, and Ning Mu immediately led the soldiers of the Northern Alliance into the passage, and Gu Xia was the last to drill in.

The aisle is not very narrow and can almost allow two people to be side by side.

This also allows the troops of the Northern Union to pass through the passage in full armor.

Stepping on the last ladder, Xia was pulled out of the passage, and after looking around, the dense crowd had already filled the small warehouse.

After Ning Mu and Yuan completed the integration of their troops, they began to fight.

This time, their task was to take the industrial and agricultural facilities in the inner city, and after seizing the important facilities, they immediately divided their troops to take the inner city wall and garrison it, and at the same time took down the enemy's high-level positions, and then sent troops to enter the military camp and other places in the Blue River, of course, to persuade the enemy to surrender.

Therefore Xia had to take fifty people to guard the small warehouse, just in case, at least to keep a way for the soldiers to survive.

Although this is not the first time that Gu Xia has led his troops to fight, this kind of infiltration battle still makes Gu Xia's heart pound.

After all, if you are not a real soldier, you will still have some stage fright.
