"Whew-"

Retracting the laser welding, the Roxhire mechanic jumped off the ladder.

"Booster No. 2 is installed, Mark let's go to the other side."

"Yes."

Carrying the ladder, Mark ran to the other side of the shuttle as fast as he could, and according to the experience of installing the booster several times, the ladder was erected in the corresponding position. Then Mark immediately ran to the truck where the missiles were placed, and carried the rocket booster with the warhead removed. By the time Rock Charles mechanic came over, all he had to do was secure the bracket.

Rock Charles sucked the bracket with laser welding while chatting with Mark to make him relax, "Boy, are you getting started?" ”

Mark, however, was only thinking about how to finish it quickly, and just agreed, "Hmm." ”

Halfway through the welding of the No. 3 fixing bracket and the space shuttle, the Shire mechanic suddenly put away the laser welding and drilled a few holes in the weld with the diamond of the mechanical claw on the outside of his arm.———

"Captain Charles, didn't you clean up the heat insulation paint and slag on the plane?"

Charles opened his metal visor and smiled at Mark through the glass visor, "Looks like you know a lot about mechanics, what you learned in school?" ”

"Yes."

"Alas, but now there is no way to do this, we can only settle for it, fortunately this is only a one-time use, let's continue."

Closing the metal visor, Rock Charles mechanic continued to weld the bracket. At this time, a violent explosion was heard in the waiting hall, and immediately afterward, a large group of marines retreated from the waiting hall. The Marines, who had previously carried out the fire blockade mission on the roof of the departure hall, also retreated and waited outside the boarding passages, where they were already the last line of defense.

Rock Shire's heart "chuckled" for a moment, and he could no longer keep the wind calm, "Ma, did you break through the departure hall defense so quickly?" Mark, let's hurry! ”

"Understood!"

At the same time, under the command of Adjutant Lin, the soldiers relied on the bunkers stacked with chairs in the departure hall earlier to block the Zerg in the airport. Without the fire blockade of the Marines on the roof of the building, the number of Zerg pouring into the waiting hall almost doubled, and soon, the waiting hall was full of Zerg. Even through the high-strength glass, the moment they saw the Marines, they grinned and wanted to pounce, that fierce appearance, which made the refugees sitting on the space shuttle frightened, and kept urging the captain to take off. In the face of tremendous pressure, the captain directly chose to close the cockpit door and let the refugees go.

"Mechanic Rock Shire, how long will it take?"

Filling up the weld of booster No. 3, Charles jumped off the ladder, Mark hurriedly moved the ladder to the right, and then went to the truck to carry the missile, even using the electromagnetic acceleration run. Rock Charles switched to a welding device and climbed the ladder to wait for Mark to carry the missile back.

"Captain Chen, it's almost there, there's still a booster to complete."

The captain warmed up the plane's engines and prepared them for takeoff, "Then I'll rest assured, thank you, Captain Charles." ”

"That's what we should do."

Mark carried the missile back and immediately attached it to the shuttle, and Rock Charles mechanic picked up the laser welding and bracket and immediately began to fix it. In just a minute, the last booster was installed, and with the help of a tractor, the shuttle headed for the runway. Watching the shuttle go away, Mark held on to the ladder for a while, and no one knew what he was thinking. But if anyone saw his now confused eyes, they might be able to guess something.

"Mark, the last space shuttle is waiting for us, what are you doing in a daze?"

Mark turned to look at Charles' feet, and saw that the ground was trembling slightly, "I, Captain Charles, get out of the way!" ”

An arrow rushed over to lift the Charles mechanic, and Mark immediately jumped more than twenty meters away with an electromagnetic bullet. In the next moment, a bloodied tunnel worm cut through the hard concrete and appeared where Mechanic Rock Shire had been standing before.

"Whew-"

The tunnel worm broke through the ground and raised its head to the sky with a loud roar, and then it began to spit out. At first, it was a viscous cyan liquid, and then there were small grinning insects. After discovering that they could not easily break through the human defenses, the Zerg used this leapfrog tactic to bypass the waiting hall blocked by the human forces from the underground and directly attack the tarmac.

"Damn!" Because it was an emergency jump, Mark didn't have time to activate the pulse thruster on his back and fell heavily to the ground. The hard landing caused the "Ripper's" leg drive to a brief pause, and the ladder in his hand was too long to break when he landed. Thankfully, Rock Shire, the mechanic who was lifted up by Mark, was taken care of and unharmed.

"Mark, what are we going to do next?"

Lowering Rock Charles Mechanic to the ground, Mark lifted the broken ladder with both hands and threw it with all his might. The ladder was stunned and inserted into the mouth of the tunnel worm, causing it to be unable to spit out the zerg normally. However, at this time, a few more tunnel worms came out of the ground, and more and more Zerg entered the tarmac by "vomiting".

"Captain Charles, I'm going to stop the Zerg, and you go find some engineers to install the boosters."

Ignoring the potential damage to the air, Mark forcibly activated the "Ripper" leg drive and rushed towards the gagged pit worm. The ladder wasn't enough to poke the pit worm to death, and Mark was going to make up for it.

"Mark, come back, the engineer is too slow! Damn, there's a space shuttle! Chen Ya, Lin Dong, Klinsim and Zhao Chuanxin pushed a missile with a cart! ”

Faced with a sudden attack by the pit worms, the human defense forces had to draw up a force for internal defense, and the two-front battle led to a surge in ammunition consumption, and soon the weapons in the hands of many soldiers were dumb.

"Bang bang bang - click - click - "

Mark was using the machine gun to sweep at a tunnel worm, when suddenly there was a sound in the chamber of the gun, and the machine gun actually ran out of ammunition. Before that, the bomb supply system didn't send out any prompts, which is unlucky?

"Damn, at this time—fuck you!"

Popping out the wrist blade of his right arm, Mark rushed straight at the pit worm, the big mouth that had been beaten to a thousand holes, and still "vomited" the worm. Hitting the foul mouth with his left shoulder, Mark swung his right wrist blade at the Torso of the Tunnel Worm for a while, until the Tunnel Worm's signal disappeared from the bioprobe, and Mark pulled his left shoulder covered with slime back. At this time, many of the Zerg who had jumped out of the stinky mouth of the tunnel were biting around the "Ripper", and there were already many scars on the armor, but Mark ignored these, raised his foot and kicked those Zerg away, and then strode one to death. Just when Mark was annoyed by the endless killing of the Zerg, a slightly familiar voice appeared in the rear.

"Mark, come over here, I've got something good here!"

Hearing the familiar words, Mark turned around in surprise and followed the source to see an officer in the armor of the Strange Engineers, who was standing on a truck stacked with missiles waving at him.

"Huh? Are you—Senior Brother Lu Hang? ”

Without machine shells, Mark didn't plan to continue to fight in the worm pile, and since the former senior brother had a way, Mark naturally wanted to take a look. Enabling the electromagnetic acceleration run, the "Ripper" ran to the side of the truck like a wind. And at this time, Lu Hang, who was full of x, began to speak.

"That's right, it's me, but now you should call me Brigadier Colonel Lu Yuanhang. You know? ”

Mark stomped on the ground, leaned over and yelled at Lu Yuanhang: "Senior brother, 100,000 is urgent, let's talk about the point!" ”

"Ahem, nonsense, I've got all these warheads equipped with impact detonators, which can be thrown out as heavy grenades. Not an average Marine, you're the only mechanical giant here, so do your best to throw these modified bombs at the pit worms for me and kill those debris! ”

"No problem!"

Grabbing a bullet the height of a ten-year-old child, Mark began to spin around with his left leg as the center. After setting the trajectory of the projectile with the help of the computer and locking it perfectly with "Look", Mark yelled and threw the bomb out like a chain ball.

"Whew———"

The cannonball slashed in a graceful arc and hit the mouth of a tunnel worm at high speed. Then, under the gaze of Mark and Lu Yuanhang, the cannonball was actually inserted into the mouth of the tunnel worm in a daze, and it did not explode. Could it be that the mouth of the tunnel worm is too soft?

Mark, who was dizzy on the ground, pointed to Lu Yuanhang's nose and asked, "Senior Brother Lu, are you tmd funny!?" If you say yes, you will blow it up as soon as you hit it?! ”

This kind of accident happened, and he was pointed at his nose by the huge finger of the "Ripper", Lu Yuanhang couldn't help but blush. With an embarrassed smile, he figured out a simple remote control, "Don't worry, I still have a backup plan - remote detonation." ”

"Drip-"

"Bang-" With a loud bang, a ball of fire covered the tunnel worm, and when the smoke rose, the Zerg biogenesis signal in that area disappeared.

Seeing the success of his work, Lu Yuanhang jumped up happily, "Haha, Mark, how about my modified bomb?" Isn't it awesome? ”

Mark didn't say a word, took out another modified warhead from the van, and spun it again with his left leg as the center. This time, he targeted the nearest pit bug to the runway. The last shuttle had already been fitted with two boosters, and Mark had to clear the way for them.

"Senior brother, I hope you don't have to press it again this time."

Looking at the darkening sky, Lu Yuanhang smiled, "Don't just throw it at that thing's mouth, it's not okay if the impact force is too small." ”

"Understood, come on—reckless bombs!" With a loud roar, Mark threw the cannonball out.

The corners of Lu Yuanhang's mouth twitched, and he said: "The bastard boy of Malegobi, Malegobi"
