"Sit tight!"

Sun Tan sped up in the direction Mark had just said, and the spacecraft suddenly lowered its altitude and flew almost close to the ground, all kinds of signal lights and other obstacles smashed on the wings of the spacecraft, and fragments of various debris flew in front of him, and the field of vision suddenly became chaotic and crowded.

Such an extreme flight method is a great test of the spacecraft's stability system, this alone makes the fighters of Xingyao City out of reach, after throwing off a batch of heels, Sun Tan pressed the trigger on the operating stick, and the attack crosshair appeared on the screen, and the unmanned fighters arranged on the two wings fired quickly, and the dense high-energy laser attack lifted the metal plate on the ground, and the ground destroyed by the high temperature burned a bright fire, and the edge of the metal was bombarded with a circle of red-hot holes.

The spaceship rushed into the ground from the breach with an unstoppable momentum, this move stunned the pursuers behind, and the breach was just a little bigger than the spaceship, this kind of accuracy was jaw-dropping, if it deviated a little, it would hit the ground directly, even if the structural strength was high, it would crash if it hit it at that speed.

"Colonel...... What to do...... Are we still chasing? "The pilot inside a fighter jet hurriedly used the communication report.

"Nonsense, do you know what's down there? Why are you waiting if you don't chase it? ”

"But there's ...... In the unlikely event of an engagement that destroys the facilities inside......"

"The enemy must be stopped before they reach the core! If you dare to do something, you will die! ”

"Yes...... Be. ”

The fighter group received the order and had no choice but to chase Mark and their ship into the ground, their agility was not more than a star and a half worse than the ship, and they crashed four or five of them when they chased down.

The environment under Star City is intricate, after several transformations over the past two centuries, the huge supporting structure is as crowded as the inside of a beehive, crisscrossed by giant steel beams tens of meters in diameter, and some structures will change with the movement of the entire Space City, flying in such a place is simply a suicidal act.

Sun Tan drove the spaceship to rush to the front, and the gap in technology became even more obvious after entering the complex environment, the performance of the aircraft was a little bit different, and the strength shown was a big difference, the density of the fighter group that was originally chasing after was much smaller, and the crowded flight space slowed down their speed, and there were very few people who could keep up with them in this case, and Sun Tan didn't have to worry about whether he would fight with them.

Several small flying detachments tried to make a detour to flank Suntan from the front, but the fighters in charge of intercepting it did not dare to use heavy weapons, and the underground facility contained not only important steel beams supporting the ground, but also many energy pipes and oxygen hubs, which were very vulnerable to damage and could be damaged...... The cities above, especially those vital oxygen facilities, would be destroyed before they could be repaired, and millions would die of lack of oxygen in a matter of hours. The interception team constantly attacked with the machine guns mounted on the fighters, and not to mention the first hit, even if it hit the command ship of Mark, it was not painful.

"Right up front, that's what the blueprint says." Mark vaguely recognized their location, which looked like a huge steel labyrinth, dimly lit beneath the city, and with no signs or references, it was difficult to pinpoint his location with such a rough structural drawing.

Fortunately, Mark had been lost in the maze of thoughts for a long time, and the experience of hibernation made him very different, and now his spatial memory ability is far beyond ordinary people, and he can judge his approximate position.

"There shouldn't be a mistake, the collision track is the central framework of Star City, and no matter how many times it has been rebuilt, it will not change this important structure." Sun Tan turned on the probe at the front of the spaceship, the detection range of this spaceship is much larger than the enemy's Star City, in such a dark and crowded environment, intelligence is particularly important, and it is much greater to be able to see some environmental advantages, so they can get rid of the enemy so quickly.

The spaceship is as small as a mosquito compared to the huge structural pillars next to it, there is very little space for people to enter, only some cables used by maintenance personnel, there is not even a road that can be walked on, the large pillars of special material are old but not corroded, the surface of the metal is matte like aluminum, and it gives people a wonderful sense in the dark, as if they are diving in the deep sea, and those pillars are the spears in the hands of giants, one after another piercing from the surface of the sea and then interspersed and interspersed. The ship passed between the pitch-black spears quickly, the huge pillars seemed to be vibrating slightly, Mark didn't know if it was an illusion caused by the darkness of the environment, looking out of the porthole could not see the whole picture of a pillar, when they passed by the side of the ship, Mark felt that it was a huge wall.

Mark's instincts were correct, and after pushing forward some distance, the huge city core appeared in front of them, it was a circular reactor core that was larger than all the giant pillars, it was made of a material that was obviously different from the giant pillars, the surface was glowing with a metallic luster like brass, and a large number of pipes connected to it from all directions, from this point of view, it really looked like a big heart.

The artificial sun inside the giant sphere is constantly beating, producing majestic energy through violent nuclear fusion, and then sending it to every corner of this space city, every building, every car, and every light on the ground of the city is powered by it.

"It's over." Sun Tan's lips curled slightly, and he pressed the button of the joystick in his hand, and the attack crosshairs on the screen gathered together, and the dangerous red crosshairs converged into one point, followed by a loud explosion.

The Gauss cannon mounted on the ship fired several shots, bombarding the outer wall of the "heart of the city", and the brass surface was torn apart, revealing the shocking dents below.

"Wait, wait, why did you just open fire! It's too dangerous! Mark exclaimed.

"Don't worry." Sun Tan waved his hand, looking nonchalant, "Just scare and scare them, this bit of firepower can't even break the skin, but they don't dare to act rashly." ”

After two rounds of attack, there was a shrill siren from above, the alarm lights flickered, and the space that had been dark just now was illuminated in blood red, and the fighters who had been chasing them all the way arrived belatedly and arrived with the defense forces, while Sun Tan stopped moving and hovered the ship in place.
