My Post-Apocalyptic Shelter Levels Up Infinitely!

“You, hurry, hurry inside!”

Not caring whether that glass door of his could stop the monster coming for them, the researcher, already past fifty with graying hair, immediately tried to pull the door open and drag Su Mo in.

But before he could even start, Yu Yangyu, chasing from behind, had already rushed onto the fourth floor and was about to close in.

“Think... think of a way. Use this to power the virtual realm. Think of a way.”

Spitting out another small mouthful of blood and feeling his chest less tight, Su Mo laboriously pulled a palm-sized energy stone from his pocket and threw it at the laboratory doorway.

He had snatched it up while racing between floors earlier.

Compared with alien races, human stamina would always be a weakness.

Simply fleeing for his life was not much use in front of a monster like this.

To win, to live, he needed a plan.

And now...

“All right, all right. I’ll go make a simple energy transmission device. You hold on.”

Opening a small gap, the old researcher snatched the energy stone with quick hands and scrambled toward the research room on hands and knees.

Watching his back as he left, Su Mo forced himself to his feet and, dizzy and swaying, kept climbing.

He still had one last energy stone in his pocket.

And the seventh floor was where the dean of this Architecture Institute was.

If he could bring the energy stone to him, the chance of building a power-supply device would undoubtedly be greater.

“Roar! Don’t think you can escape!”

Having only just reached the fifth floor and seeing Su Mo already up on the sixth, Yu Yangyu gave a mad roar and picked up speed.

But sadly, reality was not a game. The longer the transformation lasted, the heavier the burden of that strength and defense became.

He had chased only two steps when his feet slipped. He crashed into the railing and fell in a spinning heap.

Helpless, Yu Yangyu slammed a palm onto the floorboards, smashed out a pile of rubble, and hurled it upward like a catapult.

With a soft puff, great sprays of flying stone rained down onto the sixth floor. Su Mo ducked and rolled on the ground and avoided most of it.

But a small part still smashed into him, leaving wound after wound deep enough to show bone.

“No. I have to get to the seventh floor, or he’ll smash me to death like this.”

Finding that this method worked, Yu Yangyu stopped climbing. He just kept throwing rubble upward, laying down a barrage of cover.

Sensing danger, Su Mo relied on his last scrap of strength. In the instant the stone rain paused, he yanked hard and swung his body toward the seventh floor again.

But this time, whether because the adrenaline had faded or because his body had truly reached its limit, he failed to get a firm hold and nearly fell off the seventh floor.

Fortunately two hands grabbed his collar in time, or he would have dropped.

“Young man, hurry, hurry up!”

“Hold on a little longer. Dean Ji has already taken people to start our countermeasures!”

As he was pulled onto the seventh floor, two urgent voices rang out one after the other.

At the same time an open bottle was brought to Su Mo’s mouth and carefully tipped so he could drink.

“This is Nether Energy Water.”

The familiar taste touched his lips, and Su Mo, drained to the last drop and about to sink into unconsciousness, suddenly jolted awake.

The next second he stretched out his bloody, mangled hand, seized the bottle, and gulped it down in loud swallows.

The cool, sweet blue liquid slid down his throat with a touch as gentle as a mother’s hands.

In an instant Su Mo felt the wounds on his body heal by nearly half, and his basic strength returned.

“Drink. Drink it all. You did very well. We all saw it.”

“You are the pride of us humans, the pride of our Academy of Sciences.”

Seeing Su Mo try to force himself up, the earlier voice sounded again.

This time, with his mind a little clearer, Su Mo suddenly placed the voice from his memory.

He lifted his head, and sure enough.

The so-called dean of the Architecture Institute was none other than Ai Jianfeng’s younger brother, Ai Jianqiang.

Eight years had passed, and Ai Jianqiang was long past the robust prime of those earlier days.

Now his hair was gray and sparse, his face was covered in wrinkles, and even the sides of his ears and his neck showed clear age spots.

Only his eyes still held a clear light of wisdom, and the look Su Mo knew so well.

“Right. Dean Ai, hurry and make an energy transmission device. Get the virtual realm running!”

“That monster. He can still come up.”

Suddenly a chunk of rubble smashed into the wall of the seventh floor and jolted Su Mo alert.

On the seventh floor there was nowhere left to retreat, nowhere left to flee.

If Yu Yangyu made it up here, Su Mo, who had recovered quite a bit of stamina after drinking the Nether Energy Water, could of course keep fleeing downward.

But Ai Jianqiang and the top researchers on this seventh floor were frail. They would never escape a maddened Yu Yangyu.

The only way was to strike back.

The only way was to strike back with the virtual realm.

“Oh? So you know about the virtual realm.”

“But that thing hasn’t been a secret for a long time. Since they could cut the power, they must have prepared for us restoring it.”

Taking the energy stone Su Mo handed over, Ai Jianqiang first glanced at a watch-like device on his wrist, then shook his head with a kind smile.

“Rest easy, young man. You are the hope of humanity’s future.”

“It is still far from your turn to step forward and protect us dying old fools, this pitiful Academy of Sciences, and this rotten territory.”

“The time is almost here. This once, let them see properly, try properly, taste properly.”

“Just how much fury we dying old dogs have been holding down in our hearts.”
