In two months, this soldier insect actually wandered around the underground passage for thousands of miles, which shows that the Zerg is long enough in the underground passage of Planet P.

Going out of the communication room, Yu Nan did not continue to watch the training of Bo Ji and the others, he walked to the roof of the outpost building to bask in the sun, but in his heart he was pondering the coordination skills of the mecha team.

This is the first mecha squad in the world of the Galaxy Clan, and as the first squad leader, Yu Nan needs to make a training outline for mecha soldiers, and he also has to standardize the way of fighting, and there are actually a lot of things.

Knowing that there was a mission the next day, Berkey, Sibo, and Rex, who needed to attack, rested early, and Lorencia and Peder needed to guard the base, and they accepted the mission honestly without saying anything.

In this sortie, Berge was in charge of her dedicated A-type mech, Sibo was in charge of the C-type mech for fire support, Rex piloted the T2 air combat mech as a high-altitude cover, and Yunan piloted the high-speed assault B-type mech.

Early the next morning, the four mecha left from the mouth of the valley, the heavy mecha stepped on the ground, surrounded by bursts of rumbling, half an hour later, the mecha team had reached the hilly area, just as everyone was about to spread out the vigilance and wait for the arrival of the transport fleet, Yu Nan suddenly enlarged an external surveillance screen.

"What's wrong?"

Emily, who was sitting in the co-pilot, asked alertly, but she looked at the picture with only a bare hillside and nothing else, Yu Nan adjusted the picture, there were a few small grooves and a dozen small potholes on the hillside, and there seemed to be nothing special.

"Look closely, what do you think are these trenches and pits?" Yu Nan didn't answer, but prompted.

Emily quickly looked at it, her face changed and she said:

"Bug scratches, bugs here."

Yu Nan smiled and put the picture back in place and said:

"It's strange that there are no bugs on Planet P, but don't worry, the bugs in this daytime will not attack easily, especially when you find these four huge mechas, although the soldiers and bugs have low IQs, the bugs that command them may be very powerful."

Bugs have leaders, Yu Nan has already reminded Emily, and Emily also told her father about this guess, but the people at the top thought that even if the Zerg had a leader, it would be about the same wisdom as the queen bee and the queen ant, but they didn't expect that the IQ of the mother worm was even higher than that of humans, and she could change the structure of the Zerg to reproduce the corresponding bugs according to the changes of war.

Compared with the discovery of Planet P by humans, the Zerg have been breeding here for an unknown number of years, and the appearance of Zerg in the entire Big K Star Domain proves that they must have a way to carry out interstellar migration.

If you can think that the Zerg can migrate interstellarly, you can know that they are actually very powerful, and humans can also be prepared and prepared, and now, the military high-level is fighting for their own interests to build a large base before Planet P is clearly investigated.

Yu Nan believes that Planet P has a particularly large army of bugs, but the mother worm hides the army when the humans do not appear in a big way, but this time the human army has established such a huge base here, it is estimated that the Zerg will have a real war.

On the surface of Planet P, it is normal for Zerg to appear occasionally, if there are no traces of bugs here, Yu Nan felt strange, he turned on the bioradar to scan the surroundings and ordered:

"Rex high-altitude reconnaissance, this is the main base construction area, although it is on the granite layer, I don't dare to guarantee that there is no Zerg hole, once I find the traces of the Zerg, I will report immediately.

Berge chose the high ground to defend on the spot, and Sibo and I patrolled the flanks, and the action was ......"

The four mechs scattered and quickly patrolled within a radius of dozens of miles, and just after patrolling, hundreds of large transport boats appeared in the sky from the clouds, and Emily's communicator flickered for a while, and she said:

"The commander of the landing fleet, Colonel Bali, asked about the situation on the ground."

Yu Nan looked at the reports of each mecha and said in a deep voice:

"There are no traces of the Zerg in the area of 50 kilometers in diameter, but the scans show that there are very wide fissures in other places except for the integrity of the construction area, and it cannot be ruled out that there are Zerg caves deep underground."

Emily sent the message, but after a moment she pursed her lips and said:

"This guy is good enough, and directly asked us to keep patrolling on the perimeter, and they are going to set up the base headquarters and the internal defense wall today."

Yu Nan glanced at the transport fleet that had descended to the ground, and said in a low voice:

"Regardless of what they are doing so much, our duty is to protect the engineering troops, keep patrolling, Rex cruise, and meet in coordinate seven in an hour."

The efficiency of the Federation's engineering troops is very high, because the peripheral bases in this era are all combined template structures, and the good alloy plates are constantly combined in the hands of the engineering robots, and they only need to be connected with a click, and the turrets of any base can be quickly constructed.

For most of the day, a gentle hillside has been covered with a flat alloy floor, a thirty-meter-high building has been assembled, and with the construction of the outer wall, a transport ship has driven into the base, and countless equipment and supplies have also moved towards the building.

Around the base, fifty assault armored vehicles with plasma turrets surrounded the guards, and thousands of soldiers were also waiting solemnly, but they still had a kind of envy in their eyes when they saw the four mechs patrolling the perimeter.

Motorized infantry, there is a peculiar legend in the Federation, the battleship is responsible for the aircraft, the infantry is responsible for death, every time the battleship throws the mobile force to the ground and flies away, the rest is only the motorized infantry fighting on the ground and sending it to death.

Over the years, the Zerg have fought with the Federation Army, the Zerg has been wiped out at least by millions, and the human army has also suffered hundreds of thousands of casualties.

After the layout of the core area of the base, Yu Nan asked the mecha group to gather on the high ground of coordinate seven, where the engineering troops also built a temporary station and mecha warehouse for them, and dozens of mechanical maintenance workers from the fortress came to overhaul the mecha.

In normal times, these mechs are maintained by the personnel of the base themselves, and they can enter the mission mode, the pilot is the driver, and someone must be responsible for the maintenance, which is the case with the maintenance workers sent by the Fortress of Elsie this time.

Seeing that it was close to dusk, Yu Nan looked at the direction of the base on the defensive wall of the heights, but he was always worried that insects would appear.
