My Doomsday Battleship RV.

After approaching the building, Liu Xi didn't immediately rush inside. Instead, he stopped about ten meters away from the main entrance.

Once stopped, Liu Xi threw a fireball at the front door. The fireball hit the door and instantly ignited it. In less than three minutes, the entire door was completely burned away.

As soon as the door was gone, the zombies inside the building began to claw and squeeze their way out, completely disregarding everything else. Liu Xi was prepared for this. Seeing the zombies about to burst through the doorway, he launched another fireball, hitting the center of the group.

Instantly, a dozen zombies were engulfed in flames. Watching the burning zombies, Liu Xi dodged aside, avoiding the ones rushing towards him. Landing nearby, he immediately threw another fireball at the spot where he had just been standing.

With two or three more dodges like this, Liu Xi gained several hundred points and over fifty crystals. Seeing that no more zombies were coming out of the building, he turned to look at the horde following him, noticing they had regrouped.

Frowning slightly, Liu Xi realized he had been a bit overconfident. He could handle a few thousand or even tens of thousands of zombies, but dealing with hundreds of thousands was pushing it. Unless his mental strength improved significantly, he'd have to run.

Liu Xi sighed, threw seven or eight fireballs behind him, and then turned and ran into the building without looking back.

Listening to the steady increase in his points, Liu Xi knew his actions were worthwhile. He ran all the way to the roof, closed and locked the iron door from the outside, then leaned against the wall, gasping for air.

Liu Xi couldn't help but feel a bit emotional. Even though he was incredibly powerful, climbing over a dozen flights of stairs still left him breathless.

After a few minutes, Liu Xi finally recovered. Hearing that the building was quiet, he walked to the railing and looked down. The base of the building was still swarming with zombies, wandering aimlessly. Having lost track of Liu Xi, they had returned to their dazed state. Liu Xi breathed a sigh of relief.

With the zombies no longer chasing him, Liu Xi sat down, ate something, and began to recover his mental strength. He was feeling lightheaded and sleepy due to the excessive use of his powers.

Liu Xi thought to himself that he should use his powers less often and avoid overexertion; the feeling was truly unpleasant. As Liu Xi closed his eyes to rest, the government troops sent to respond to the university campus finally arrived.

However, the once-spirited army now looked utterly exhausted.

Seeing the university campus ahead, the troops, who had been cautiously advancing, finally broke into smiles. Their weary faces relaxed slightly.

The tension they had been carrying finally eased upon seeing the university campus.

But upon seeing the scene at the entrance, they were stunned. The university gate was completely blocked, making it impossible for vehicles or even people to pass through.

Finally, the officer at the head of the column had no choice but to signal the army to halt, issuing several orders in succession before turning his attention back to the impassable gate.
