The first half of the interstellar pirate advance with great ease, and it seems that the defenses of Iron City have given up resistance. However, when the interstellar pirates broke out of the "safe zone" and arrived at a place three hundred kilometers away from the city center, special grenades rose under the ruins of the buildings in the area where the pirates passed!

Sensing the launch of these grenades, the interstellar pirates who rushed to the front immediately gathered together in small teams. The one in the front row of the squad held a giant shield, and the heavy war mecha, which was generally more than fifteen meters tall, knelt on one knee and held up a giant spliced superalloy shield with a height of more than ten meters in his hand. And inside the superalloy shield, dozens of small plasma shield generators supported their respective plasma shields almost at the same time, forming a semicircular plasma shield with a diameter of more than thirty meters!

At the moment when the heavy mech made a defensive stance, the relatively small war mech in the back row of the squad quickly hid behind the plasma shield propped up by the heavy war mech. Even the war mechs have to hide, let alone the individual mechs in the squad that are like little chickens.

No one has used the mech's equipped high-energy particle guns against this particular grenade, as the grenade doesn't explode too violently.

The true lethality of this so-called "ray grenade" lies in the internal mechanism that is activated after liftoff. The well-trained "Star Pirates" squad had just finished their defenses when these fast-rising grenades exploded less intensely. And just after the grenade shell was detached from the bomb body, dozens or hundreds of energy beams of high-energy lasers and high-energy particle beams instantly exploded in all directions!

Even though most of the interstellar pirate squads were prepared in advance, the first wave of interstellar pirates still suffered a lot of losses under this round of abrupt sneak attacks. Even if a heavy war mech encounters this kind of attack, it will only suffer minor injuries at most, and a light war mech will not be scrapped even if it hits. But the individual mechs in the squad can't withstand this targeted attack method at all! If you don't hide in the protection area of the Heavy War Mecha in advance, or if the shield supported by the Heavy War Mecha does not block all the attacks, then the individual mecha will be greeted by the mecha being ignited, melted, and burned through! No matter how heat-resistant metals are, they will only become liquid, gaseous, or even plasma in the face of ultra-high temperatures that can easily reach tens of millions of degrees Celsius.

Because of the thick armor of the war mecha, even if the outer armor is melted, the internal armor will be supported by the extreme consumption of ray ability, but the relatively thin armor of the individual mecha cannot hold up.

Fortunately, this unexpected attack can only have the first wave. And after the first wave of attacks has worked, it's time for the interstellar pirates to launch ground-penetrating missiles into the ground where the target is located.

However, it is likely that this attack will not work. Because the enemy is not stupid, he retreated in advance before these grenade launchers fired ray grenades. It's like a preset remote-controlled bomb, which belongs to the category of traps.

Ground-penetrating missiles quickly burrowed beneath the surface, detonating grenade launchers hidden underground, making the roads in an area ahead safer.

However, it was like entering a minefield, and an interstellar pirate who had suffered a loss could no longer advance as fast as before. In the front row, the reconnaissance unit goes first, responsible for investigating the suspicious vibrations underground. Beneath the surface, a series of pangolin-like burrowing robots dig forward quickly, trying to eliminate the dangers hidden beneath the surface in advance. Even if it cannot be ruled out, it is necessary to detect it in advance and give early warning.

No one wants to fall twice in the same pit, if it weren't for the rush of Iron Blood City's defensive operations this time, if the previous sneak attack had been planned for a long time, it would have completely disabled the interstellar pirate vanguard that had not been adequately guarded before!

The speed of the elite troops at the front slows down, and the speed of the regular troops that follow will naturally be even slower. Fortunately, the interstellar pirates have strong outer space firepower support, and as long as they fight steadily, they are not easy to be overturned by stubborn enemies. From the counterattack tactics of the defenders of Iron Blood City, the attacking interstellar pirates felt the enemy's determination to resist. In the case of a conventional attack and defense, the most likely behavior of the defending side is to hide in the underground fortifications that are thousands of meters away and the territory is as wide as an underground labyrinth, and fight guerrilla attacks with the attacker's depth of several thousand meters underground. Taking advantage of the information on the terrain, the defending side can calmly deal with the attack of the interstellar pirates. And the interstellar pirates are destined to not stay in the cave for a long time, so it is impossible to go underground and force the defender to fight desperately with him, but will only focus on robbery.

The cause of the enemy's anomaly was quickly discovered. Intelligence feedback from the hidden spy in Ruixue City made the command of the interstellar pirate outer space aware of the change in the situation. Obviously, he didn't give an order to the spies in Ruixue City, but the spies received an order to act! Under the activities of the spies, the Ruixue Group sent a strong support force to Iron Blood City! Because of the outing of this support force, the defense of Ruixue City has been greatly weakened! It seems that the moment when this support force goes to Iron Blood City to support the operation is the best time for the interstellar pirates to invade Ruixue City.

However, the primary target of this trip is not Ruixue City as originally planned, but a super god space user named "Zuo Zhe"! According to the orders of the superiors, even if the invasion of the Earth Cave Star fails this time, Zuo Zhe must be beaten into a vegetative state and brought back to the Earth Far Planet System! Yes, the pirate commander received an order to turn Zuo Zhe into a paraplegic vegetative person! Only by turning Zuo Zhe into a high paraplegic vegetative person can Zuo Zhe's threat be lifted!

The situation has changed, since Ruixue City has revealed flaws, and its own side has planted a lot of inside lines in Ruixue City, it is impossible to miss the attack on Ruixue City. Fortunately, the interstellar pirates still have a large number of landing combat units in outer space. Now that the second target has been identified, it's time for them to land on the Cave Star.

Night is far from coming, and Zuo Zhe seems to be hiding under the surface at this time. However, Ruiya told Zuo Zhe a shocking news! Although this news is not confirmed, it is not difficult to confirm!

"Your mother may be a descendant of a wealthy family?" Listening to Ruiya's words, Zuo Zhe immediately became interested. Zuo Zhe has long been fed up with the days of working alone, and he just wanted to find a backer, but he didn't expect the backer to come up by himself!

"Zuo Zhe, please use your special ability to help me invade the database of the high-level Rui surnamed Rui in Ruixue City, help me check their genetic information, and see if my genes are related to the genes of the Rui family."
