"...... Du" didn't know where the melodious sound of the horn came from, if it was someone who had just come to Alpha Star, they might still think it sounded good, but the soldiers of the 106th Division, who had been fighting here for several days, were all nervous, because this was the signal for the Zerg to attack.

"Where is it?" Qin Hao quickly found the bug that emitted the horn sound through his enhanced vision, which was a relatively small bug, only fifty or sixty centimeters long, with a big trumpet-like thing growing on the top of his head, and it was this thing that emitted a loud and melodious horn sound.

"Toot ......"

"Toot ......"

With the first horn sounding, followed by the horns around the Z3 Heights, it was clear that the Zerg was about to start a decisive battle.

"Squeak ......" For a while, the entire battlefield was full of insect chirps, and a large number of giant beetles swarmed up and rushed to the Z3 highland!

"Boom, boom, boom......" Gauss position artillery continued to fire, hundreds of giant beetles were blown to pieces, but more insects continued to rush up on the corpses of their companions, and the insects all over the mountains could not be killed.

......When the bugs rushed into the range of the electromagnetic rifles, the soldiers of the 106th Mechanized Infantry Division also opened fire, and they fired wildly with their electromagnetic rifles, and the steel torrent of bullets tore the giant beetles to pieces.

"The Eastern Front is tight! Request support! ”

"The Southwestern Front is tight! Request support! ”

……

Because Qin Hao was James' personal guard, he had been staying here at the division headquarters, so that he could clearly hear the reports of the defenders from all directions calling for help.

As the battle progressed, the defenders of almost every defensive node fought very hard, and although the ordinary giant beetles could not withstand the fire of the Federation Army, they were too numerous to kill.

"Division Commander, there are a large number of giant beetle leaders in the southeast! They can't stand it anymore! The adjutant shouted loudly, because the whole battlefield was filled with the sound of insects and artillery fire at this time, so even if they were face-to-face, as long as they didn't shout loudly, they couldn't hear what the other party was saying.

"Let them abandon the first line of defense and retreat to the second, and at the same time activate the mines between the first and second lines!" James ordered, because he knew very well how powerful the leader of the giant beetle was, and it was impossible to block their attack with the outermost simple fortifications, and if he stuck the first line of defense, it would only bring heavy casualties to his troops.

Now for James, it is completely possible to exchange space for time, as long as it is delayed until air support arrives, then the lost position can be completely recaptured, so the most important thing now is to preserve strength.

"Boom...... Boom ......" At this moment, the bunker of the division headquarters shook violently.

"Report, a large number of plasma bugs have been found in the northwest!" The adjutant yelled loudly.

"Activate the emplacement radar to lock them on, and let the Gauss cannon fire!" James roared, compared to the leader of the giant beetle, the plasma worms are more threatening, the plasma they spray is very terrifying, the human soldiers are almost touching death, and even the Gauss defense cannon will be destroyed by these plasma worms, so when the location of these bugs is discovered, they must be eliminated as soon as possible.

"Yes!" Soon, the gun position radar locked on those plasma bugs, although these bugs are all good at learning and know how to change places with a shot, but the speed of plasma bugs is too slow, they don't have time to run far, they will be blown to pieces by the overwhelming artillery fire.

"Boom!" At this time, the bunker of the division headquarters once again floated and shook, and this time the epicenter was obviously from the ground!

"Damn! These insects really can't forget to dig holes! James spat out, but fortunately, the position on the Z3 Heights had been built, and the ground was all covered with a metal floor thirty centimeters high, and although the bugs could burrow into the ground, they could not penetrate this layer of steel floor, which was also a trick learned by the Federation after several attacks.

"Huh......" Qin Hao sat quietly on the side, as James's personal guard, he didn't need to go out to fight, but he couldn't interfere in the affairs of the headquarters, so he could only sit there and be lucky.

"Boom!" There was another violent tremor, as if something was frantically hitting the steel floor underground.

"Huh?!" Qin Hao felt his eyelids jump, and the back of his neck was numb, and that sense of crisis appeared again.

"Divisional commander, it's not safe here!" Qin Hao said loudly, he had now begun to believe in his hunch, because in the previous battle, his hunch had never missed!

"Oh!? The alloy floor here at the division headquarters is twice as thick as other places, so there should be nothing wrong here, right? James said that although he firmly believed in the solidity of the division, Qin Hao's words still made him have some scruples.

"Boom!"

It was another violent impact, and except for Qin Hao, the rest of the entire division headquarters were all staggered, because the entire alloy ground was knocked up, and several civilian female soldiers even fell out directly, knocking on the table and hanging colors.

"Click!" Although the alloy floor is solid, it is not a whole after all, and the rivets at the connection position of several alloy steel plates were knocked open, although they were not completely broken, but everyone knows that it is not safe here!

"Evacuate! Speed Evacuate! Qin Hao took the lead in withdrawing from the division headquarters with James, followed by other officers who also evacuated one after another.

"Adjust two Gauss guns to aim at the division headquarters! Three battalions surround here! James was also in danger, and he immediately ordered to take defensive measures, after all, the kind of guy who can break the alloy ground is by no means an easy bug to deal with, and it is difficult for ordinary soldiers to destroy it without a heavy weapon like a Gauss cannon.

"Boom ......" Not long after Qin Hao and the others ran out of the division headquarters, two loud noises were heard in the division headquarters, and the roof of the bunker was overturned.

A huge head poked out through the roof of the division's bunker, a monster that looked like a snake or an earthworm, it was seven or eight meters tall and about two meters in diameter on the ground alone, and it was definitely a behemoth.

The most terrifying thing is that this insect does not have eyes and nose or other organs on its face, but it has more than a dozen rows of teeth in its large mouth, and the ring-shaped teeth are accompanied by the agitation of the muscles, grinding the boulder to pieces, if people are swallowed by it, the consequences can be imagined.

"Fire!" At the moment when this insect emerged, the Gauss cannon began to exert its might, and the two shells directly hit this guy's body, but the skin of this giant insect was very tough, and the moment the shell hit it, it bowed slightly, and then stretched hard, and the two shells were actually bounced out, and they didn't explode around it at all!
