"Wait, just surviving for three hours doesn't seem like a challenge for you guys!" Xiang Lingxi, who was floating in mid-air, suddenly had a good idea, "Tower defense games are still quite popular in the outside world, why don't you try this!" ”

Xiang Lingxi pointed to the central area of the military building, where an irregular purple crystal with a diameter of more than 3 meters slowly suspended about a meter above the ground.

"Your task now is to prevent this crystal from being destroyed by the Zerg within three hours, and if it fails, we will go to the Flame Pluto for three hours this afternoon!" Xiang Lingxi said coldly.

When it came to the Flame Pluto, everyone shuddered, no one wanted to go to that hellish place a second time, and the gravity far beyond the earth was not something that ordinary people could resist, let alone the scorching air like flames.

"This woman really knows how to play!" Yu Hao stared at her viciously, although he also liked tower defense competitive games, but when he became a character in the game, the feeling was unimaginable to outsiders.

"Everyone, stay in all directions, and don't let any bugs fly in!" Yu Hao stared intently ahead, those flying zergs were already very close to them.

This kind of Zerg is called a jumper, their body length is about two meters, they have a strong ability to move, and have a short flight ability, they are quite powerful elite troops in the Zerg, and they can even easily cut off human heads and guns when flying at high speeds.

"Da Da Da!" The automatic fire enveloped the air units in an instant, shattering the shells of the jumpers, but their vitality was so strong that even if they were hit by dozens of shots, they might not lose their aggressiveness.

Several jumpers were shot down by powerful machine guns, their corpses shattered outside the impregnable military walls, but several broke through the fire network and charged the students inside the base.

At this time, Yu Hao didn't have time to worry about the others, because there were already three jumpers about to fly in front of them, one of them was almost beaten into a sieve, although it was already dying, but the strong inertia still made it have a terrible aggressiveness.

"Give me two, and you can solve the rest of the one!"

Yu Hao jumped up, cut the dying Zerg in half with a sword, his body stayed in mid-air for a moment, and then stepped on the back of the hapless jumper, and then this force rose into the air again, directly pounced on the menacing jumper.

Although the jumper was shot a few times, it did not affect its mobility and aggressiveness, and its sickle-like forelimbs crossed directly in front of him to split Yu Hao's body.

However, it far underestimated Yu Hao's strength, the more than 100-pound Zigang heavy sword was wielded by eight times the strength of ordinary people, it was like a heavenly demon descending to earth, and the jumper was directly slashed under the city wall.

Although the pair of scythes had not been cut off, the bones inside had almost all been shattered, but it was not dead, it fluttered on the ground a few times, trying to rush up, but the wall more than ten meters high was extremely smooth, and it could only stare dryly below.

Almost at the same time, Fang Ruoyuan also made a move, her physical fitness had almost reached a level close to six times that of ordinary people, and the weapon in her hand was obviously not an ordinary sword, but it should not be specially built.

Yu Hao could almost judge the strength of the jumper in the fight just now, probably about G-level, and his physical fitness should be about five times that of ordinary people, Fang Ruoyuan only learned a martial art called frost swordsmanship for the time being, and between the swings of the long sword, there was a faint trace of frost and mist, but she obviously hadn't practiced it yet, if this martial art was practiced to a high depth, it was enough to directly freeze the weak creature with cold air.

But even so, the jumper's movements faltered, and her long sword slashed at the pair of forelimbs, and a tremendous force came from her hands. After all, it has the potential energy carried by flight, and its attack power cannot be measured with five times its strength.

Fang Ruoyuan did a gorgeous somersault in the air and stood firmly on the ground, and the Zerg also landed on the city wall, but its forelimbs were covered with a thin layer of frost, and there was a bleeding opening.

The frost could not freeze it, but it made the blood from its forelimbs quite viscous, and almost half of the jumper's body was in a state of near-paralysis.

At this time, Fang Ruoyuan moved again, and her long sword stabbed directly into the head of the sluggish jumper, destroying its head to the ground.

She turned her head and threw a smile at Yu Hao, as if to say that she was no worse than him.

"Be careful!" Yu Hao did not hesitate to cast a battle qi explosion, and when Fang Ruoyuan reacted, Yu Hao's Zigang heavy sword had already chopped off the forelimb that was swinging towards Fang Ruoyuan.

As Yu Hao became more and more proficient in the use of battle qi bursts, he could already explode for a short time, but he couldn't control it in an instant, and I am afraid it would take a lot of cultivation to reach this level.

"They have a strong vitality, don't take it lightly if they don't die completely!" Yu Hao instructed.

Fang Ruoyuan blushed and nodded, she was older just now, if Yu Hao hadn't made a move on the real battlefield, she would already be a corpse now, after all, this jumper was not much weaker than her.

In addition to the two of them, people from several other directions were more or less attacked by a few jumpers, but with everyone's cooperation, they were all shot down and killed, and only a few people received some minor injuries.

But the form is still very tense, after all, this is only the vanguard, and the time has only passed for a few minutes.

Finally, the Zerg army arrived, and the green monsters known as warriors were the largest of the race, they were about 1 meter long and two meters high, they were tenacious and agile, and they had terrifying aggression on both their forelimbs and gastropods, but the most terrifying thing was their tidal numbers.

......At this time, all the automatic weapons on the city wall were fired, machine guns, artillery, and all kinds of large war weapons roared to tear the bodies of the warrior zerg to pieces, and a few dozen meters away from the city wall had been piled up layer by layer of corpses. 、

However, these weapons were only partially blocked, and a large number of warriors crossed the blockade of the line of fire, and they were put together like human ladders, and the Zerg in the rear stepped on the bodies of their companions and rushed towards the military building.

"Stop, don't let any of the Zerg in!" Yu Hao roared, and several zergs had already jumped up in front of him......
