Chapter 64: Evolution Serum, Heretical Corpse Puppet!

A single dormitory confronting a monster that required two hundred dormitories to fight against!

This idea was utterly insane.

Yet, Xu Lang might actually be able to pull it off!

Besides, he didn't need to instantly max out the hostility and terror level to the heavens; he could take it step by step.

However, for now, overthinking was useless. He should first harvest the profits of this round to the absolute maximum before considering anything else.

At this thought, Xu Lang no longer hesitated and chose to upgrade the Zombie Virus Immunity Serum.

【Nightmare Coins -60】

【Gene Optimization Serum】

【Type: Medicine】

【Level: 2】

【Effect: Increases Constitution by 3 points upon injection, grants immunity to zombie virus, influenza, hepatitis B, and other viruses】

【Upgrade Requirement: 145 Nightmare Coins】

【Description: An excellent biochemical product, subcutaneous injection will do... I don't eat protein powder when I work out; I usually take protein powder after working out.】

"As expected, a Gene Optimization Serum." Xu Lang felt reassured.

He was safe on this one.

Instead of using it, he chose to continue upgrading.

Items that boosted basic attributes all shared a single rule: repeated usage was useless.

Moreover, a mere three points of Constitution wasn't nearly enough to satisfy Xu Lang's ambitions.

【Nightmare Coins -145】

【Please select one of the following upgrade directions within one minute】

【One, Ability Serum: Grants a random ability upon use】

【Evolution Serum: Grants 4 points of Constitution and 2 points of Spirit upon use, vastly enhancing cellular activity】

"A bird in the hand is worth two in the bush..." Muttering to himself, Xu Lang chose the Evolution Serum.

While the Ability Serum was tempting, it was far too random.

【Evolution Serum】

【Type: Medicine】

【Level: 3】

【Effect: Grants 4 points of Constitution and 2 points of Spirit upon use, vastly enhancing cellular activity】

【Upgrade Requirement: 340】

【Description: The first step toward biological perfection... Steady and solid progress will make you strong.】

"The cost to upgrade to level 4 is 30 Nightmare Coins less than the Ability Serum. It seems abilities are somewhat more prestigious after all," Xu Lang thought to himself.

He currently had 108 Nightmare Coins left. After another night's sleep, he would have 452 Nightmare Coins, which would be enough to reinforce the Evolution Serum once more.

Xu Lang put the Evolution Serum into his inventory and then heard a commotion from the bathroom. Tong Qi walked out, her slightly chubby cheeks tender and delicate, blooming like a lotus rising from clear water.

"Brother Lang, come help me blow-dry my hair." Tong Qi curled her tiny toes, feeling extremely shy just looking at Xu Lang.

Not long after that intimate encounter, she was still in a bashful state.

"Alright," Xu Lang replied, rising to his feet and walking over with a smile.

The night quickly passed.

When daytime arrived, Xu Lang went to sleep right on schedule.

...

【Base Nightmare Coins 80, conversion rate 330%, total output for eight hours: 344 Nightmare Coins】

【Total Nightmare Coins: 452】

There was still about an hour before the game started, but Xu Lang didn't immediately upgrade the Evolution Serum.

With over four hundred Nightmare Coins, he could still upgrade a turret instead, leaving a little room for maneuver.

Although all signs pointed to the final outcome unfolding exactly as he had guessed, one could never rule out a one-in-a-million chance.

In truth, keeping five hundred Nightmare Coins to upgrade the main door was the safest bet.

However, he wasn't lacking in defense right now; what he lacked was firepower, so he ruled that option out.

He had no choice—his dormitory was only at level 2, which supported a maximum of two turrets.

Time ticked away. Seeing that only half an hour remained in the game's countdown, Cao Yaxuan couldn't help asking, "Xu Lang, are we really going outside to kill monsters?"

"Mhm." Xu Lang nodded, paused for a moment, and said, "If you play your cards right, you might not have to go out."

"What do you mean?" Cao Yaxuan asked.

" barring any accidents, the monsters on our tenth floor are zombies, and zombies have weaknesses. Once you kill yours, you won't need to go outside," Xu Lang explained.

"Weaknesses?" Wang Yazhi raised an eyebrow.

Xu Lang nodded, took out the *Folklore and Oddities Chronicles*, and succinctly summarized its contents.

The information wasn't complicated. With a brief summary, Cao Yaxuan and the others understood immediately.

"So this book was also obtained through a lucky skill upgrade of yours," Tong Qi smiled and said.

Cao Yaxuan nodded in pleasant surprise as well.

"No wonder you emptied out everything in your backpacks, Xu Lang, and even bought items dropped by monsters from other floors."

Cao Yaxuan was equally thrilled: "So all ten Bosses have weaknesses! If that's true, maybe we can make it into the top three!"

"Entering the top three doesn't matter much. As long as you guys are in the top ten, the reward is the same as mine. Actually getting into the top three would just waste a share of supplies," Xu Lang replied.

While players on other floors were still guessing what the Bosses were and how to clear the final stage, Xu Lang and his group were already discussing the distribution of profits as if they possessed foresight.

In Dormitory 200, the roles of monsters and homeowners seemed to have reversed.

The monsters were the humans who should be hiding, while the homeowner was the ghost!

【Dormitory Broadcast: Round 6 officially begins. The Ten Heretical Cultists have descended upon the Mad King's Dormitory Building. Please prepare yourselves to welcome them. This round will last for twelve hours.】

Simultaneously with the dormitory broadcast, thick mist rose across all ten floors and rapidly spread through the corridors.

Jingle, jingle~

An eerie ringing echoed through the hallway—crisp yet muffled, making anyone who heard it feel their head swell.

Thud~ Thud~ Thud~

Zombies came hopping out of the hallway one by one. Xu Lang found the sight oddly familiar, even somewhat endearing.

"Little Zombie is here to deliver points again," Xu Lang laughed.

Cao Yaxuan smiled as well.

Perhaps influenced by Tong Qi, when she looked at the hideous, ferocious expressions of those zombies, she actually found them a bit cute.

How should she put it?

They kind of gave off the vibe of an American Bully.

As soon as the zombies appeared, they hopped toward Xu Lang's location. There were only three in total, and before they even got close to the dormitory door, the turrets blasted them to pieces.

Then, more zombies emerged from the hallway, still in groups of three.

After several rounds of slaughtering them, the frantic ringing grew sharper, and the spawn rate of the zombies gradually increased.

Yet, no matter how many zombies appeared, they were nothing more than free kills upon arrival.

Finally, at a certain moment, the crazily chiming bell stopped. A man dressed in black robes with a purplish-cyan complexion stepped out from the hallway.

Following right behind him were two bronze-armored zombies.

None of these three monsters hopped; they walked!

Xu Lang swept his gaze over them, and the stats of all three monsters popped up.

【Ten Heretical Cultists: Corpse Overlord】

【Type: Heretical Cultist】

【Level: 4】

【Skills: Corpse Refining, Indestructible Vajra】

【Description: A once arrogant and domineering heretical cultist, cause of death shrouded in mystery】

...

【Bronze-Armored Corpse】

【Type: Undead】

【Level: 3】

【Skills: Bronze and Iron Body, Superhuman Strength, Berserk, Corpse Venom】

【Description: In life, he was a veteran soldier hardened by a hundred battles】

The stats for both bronze-armored corpses were identical.

The bronze-armored corpse was a mutated variant of corpse refinement practiced by humans, not belonging to the orthodox category of zombies. They required the deceased to have died amidst the chaos of war and be shrouded in baleful aura.
