While the expedition was still climbing the shaft, the landing site was already under fire.

Although the scattered and surrounded mechanical units were severely blasted by the "Thor's Hammer" fusion shells, they still broke through the blockade of the long-range artillery with the support of a huge number.

The next thing they have to do is a cross-defense consisting of a static Steel Fortress and a dynamic Cobra assault vehicle.

The "steel fortress" that was rushed out of the space engineering vehicle can only be regarded as a semi-permanent fortification.

Semi-dome steel armor with some shooting holes, this is the simplest fortification, even rudimentary.

Fortunately, there were enough piles of steel to defend against direct shelling from large-caliber shells, and there were no casualties among the team so far.

The Marines armoured infantry were all deployed in scattered "steel forts" that provided them with good protection and were not needed to participate in the battle at this stage.

The Cobra tank, loaded with elite armored infantry, is the fulcrum of the defensive network.

On the foggy battlefield, beams of blazing blue light flashed from time to time.

The two high-energy laser emitters on the "Cobra" chariot originally fired colorless ultraviolet lasers.

However, after the laser passes through the cold mist, the Tyndall effect causes the excited particles in the air to emit a dazzling light.

And at the end of these beams are destroyed armored combat vehicles.

Most of the mechanical combat vehicles sent by the Planetary Control Center are only light vehicles, and their own armor is difficult to resist high-energy laser attacks.

This is also what the Mamba they are more concerned about, as such an important core hub of the planetary control center, it is completely understandable to have so many defense troops, but they are only light weapons, and not even a heavyweight enemy has appeared.

"Keep on your guard!" From the command platform, Mamba ordered: "Don't let your guard down, you must not let any enemy break through our blockade line, and you must ensure the safety of the transport ship!" ”

……

"We've climbed a kilometer, and it's really deep." Lias was at the bottom of the line, and he kept looking down, but the shaft seemed to have no bottom in sight.

White Tang also said: "We've gone beyond the area of the information obtained by the previous 'high-dimensional projection scan', and further down there are really two eyes blacked. ”

Cha Mo bounced back and forth on the shaft wall like a kitten: "Why don't we try to destroy this shaft wall and see what's out there?" ”

Everyone disagreed with this risky action, and White Tang glanced at her: "You, it's better to settle down a little." ”

Fortunately, the pressure on the landing site was resisted, and now they were not in a hurry, and everyone continued to climb down in a step-by-step manner, and soon, there was a bright light from under the shaft.

"Looks like it's coming!" Lias exclaimed in surprise, "You wait here, I'll go down and have a look." ”

With that, he let go of his hook and swung in the direction of the light source.

The crowd waited for about half a minute, and Lias sent a signal: "It's safe down there, you all come here." ”

One by one, they reached the bottom of the shaft, where a ventilation duct was attached, and it was in the ventilation duct that Lias found an exit.

"This is the exit," Lias said, pointing to the iron fence at his feet, "I just looked, there should be no surveillance equipment around, and there should be no patrol posts in sight, so it should be safe." ”

White Tang nodded: "Okay, then let's go down from here, everyone be more careful, and be smart when encountering situations." ”

Opening the iron fence, the team members drilled out the ventilation duct in turn, which was a very open circular passage, which looked like the first floor of the "fortress" city, and everyone felt a little home.

"We ...... Which way to go next? Looking at the two ends of the passage, Cha Mo asked.

White Tang raised his hand and pointed in the direction: "That side is due north, according to normal circumstances, the hub of the planetary control center should be at the North Pole, and it should be right to go that way." ”

The team members began to move in that direction with their weapons and shields, and soon there was a fork in the passage, and there was a sign signal on the fork.

"This is the way to ...... Control? Is this a safe passage? Lias read the sign on it, a little undecided.

White Tang waved his hand: "No matter how much, let's continue to go north!" ”

However, just as they were walking through this fork in the road, a figure suddenly appeared in front of them.

If you look closely, it is a humanoid robot, and it also found the expedition members, and a pair of electronic eyes suddenly lit up red: "There are intruders!" There are invaders! ”

The first to move were Lias and Britz, one of them flicked their hooks and grabbed the robot directly, and the other turned into a phantom and rushed to the robot with lightning speed.

The two of them started at the same time, and the robot dozens of meters away didn't even react, and was instantly pressed to the ground by them.

Lias grabbed it by the neck and said, "Shut up, or I'm welcome!" In a moment's frustration, Lias seemed to forget that robots don't need to breathe.

However, the robot didn't care so much about him, and still shouted freely: "There are intruders!" ......'s stuck neck doesn't stop its external speaker from continuing to work.

Lias is also short-tempered, and with a direct move, the robot's head was twisted off, it seems that the robot is not a military signal, and it was actually broken directly with a twist.

Seeing that the electronic eyes gradually dimmed, Lias smacked his lips and said to Britz, "Am I too heavy?" ”

Britz shrugged: "I hope this robot is useless without a head." ”

The others also rushed over, and White Tang grabbed the robot's body: "Adjutant, can you get any useful information from this robot's system?" ”

By connecting the remaining parts of the robot, the base intelligence lieutenant said: "This is a daily patrol robot, it is connected to the security system within the entire base, and this machine wants to tell you the bad news, and now your location has been exposed." ”

Cha Mo exclaimed, "So what are we waiting for here?" Why don't you run? ”

The base intelligence lieutenant continued, "But I also have good news for you, through this security system, this machine has also obtained the location of other security equipment in the base, as well as the core hub of the planetary control center. ”

White Don shouted, "Don't sell it here, tell us the route, we'll go now!" ”
