Kill one monster, stack one poison, and I alone will poison my way across the world!

"call……"

Su Chen let out a long breath and looked at the golden [LV2] on the system notification. His nerves, which had been tense for half a month, finally relaxed.

Although the process was more agonizing than going to jail, the outcome was ultimately good.

He opened the skill panel.

【Corrosive Serpent Guard (LV2)】

Mana cost: 10 points/root.

Cooldown: 10 seconds.

Summoning Mechanism: Summons up to [X] Corrupting Serpent Guards at a time (X = current maximum number of poison stacks). Each Serpent Guard has (Constitution * 0.2) health points and lasts for 300 seconds.

Movement Mode: The Serpent Guard can move, with a movement speed of 50% of yours.

Attack Modes: 1. The Serpent Guard is a fixed turret that automatically attacks a single enemy within a 15-meter range, prioritizing the target you have locked onto. It attacks once per second, dealing (Spirit * 0.8) points of poison damage. 2. Charge Mode: After charging, the Serpent Guard increases its range, up to a maximum of 100 meters after a 3-second charge.

Maximum Limit: The total number of snake guards summoned by this skill is permanently equal to your [Poison Stack Limit]. As this stack increases, the number of snake guards summoned per instance also increases.

……

First, there's the Serpent Guard. After reaching level two, the Serpent Guard changes in the same way Su Chen had trained before.

The cooldown time has been reduced to 10 seconds, while the duration has been increased to 300 seconds.

Although it's still far from the goal of planting a snake guard permanently, which Su Chen wanted, the ten-second cooldown lasts for five minutes. If Su Chen has enough mana, he can summon hundreds of thousands of snake guards.

In addition, it can be moved and a charging mode has been added.

It can be said that the Serpent Guard has undergone a qualitative change.

Next up is the Poison Explosion skill.

[Death by Explosion from All Poisons]

Mana cost: 200 points.

Cooldown: 10 seconds.

Skill effect: Detonates all stacks of [Poison] on all targets within a five-meter radius, dealing true damage equal to [Mental * Poison * Duration].

……

The main changes to the Poison Explosion skill are a shorter cooldown and a change from a single-target skill to an area-of-effect (AOE) skill with a range of five meters.

Closing the skill panel, Su Chen glanced at the empty practice room, then turned and walked towards the metal door leading to the exit.

"Are you leaving?"

Hatsuyaki's voice rang out from behind.

She was wearing high heels, and the barbed energy whip in her hand had been put away. Behind her glasses, her eyes had returned to their original state of cold, emotionless data flow.

"What, you can't bear to part with me?"

Su Chen waved his hand without turning his head; all he wanted to do now was find a place with a bed and sleep soundly for the rest of his life.

"That's true to some extent."

Chu Ying pushed up her gold-rimmed glasses, a wistful smile curving her lips. "After all, it's been a long time since I've met a punching bag like you, someone I can curse at for fifteen days straight, someone I can curse at so thoroughly."

"If you'd like to upgrade your skills again next time, feel free to come back. I'll have a brand new vocabulary list ready for you."

Su Chen suddenly stopped in his tracks.

"..."

Damn it, this artificial intelligence is so annoying!

What kind of mental state was the person who created this practice room in when they wrote this sadistic code?

Su Chen gritted his teeth, didn't look back, and quickened his pace to walk out of the metal door.

at the same time.

The skills training hall, inside the spacious rest area.

Several students in school uniforms were slumped on a bench, their faces pale, as if they had just had their life force drained away.

"This is too difficult... This skill training is way too hard!"

A boy with a buzz cut gulped down a large mouthful of basic mental recovery potion and slapped his thigh with lingering fear.

"I only spent two hours in the character training room, and my mental energy is already completely depleted! That AI is a complete jerk, constantly forcing me to shorten my spellcasting animation. I'm a priest! What do I need to shorten my spellcasting animation for?!"

A tall, thin boy next to him also looked utterly dejected: "Be grateful, two hours is pretty good. I just tried to switch my Fireball spell to rapid-fire mode, but my mana circuit completely collapsed, and I was forcibly kicked out. My head is still buzzing."

"Sigh, this skill proficiency setting is just insane."

The crew-cut boy sighed, "Not only do they require a lot of credits, but the energy consumption is also astonishing. No wonder many people can't upgrade a single skill even after several months."

"A few months?"

The tall, thin man sneered, "Do you have some kind of misunderstanding about our school's graduation rate? Some people graduate without even leveling up a single initial skill! This stupid system is purely designed to torture people!"

As the two were pouring out their grievances, the golden door at the far end of the hall, which was always tightly closed, suddenly lit up with a green light.

"drop--"

The heavy metal door slid open to both sides with a slight hydraulic sound.

Several students in the hall instinctively turned their heads to look.

A boy with messy hair, bloodshot eyes, and a weary gait walked out from inside.

It was Su Chen, who had just finished fifteen days of grueling training.

The air in the hall suddenly became quiet.

The bottle of medicine in the buzz-cut boy's hand was suspended in mid-air, his eyes widened little by little, and his mouth was so open that it could fit a duck egg.

The tall, thin man jumped up from the bench as if he'd seen a ghost.

"Holy crap?"

"Is that person...the one who went in two weeks ago?"

"Yes! I remember him! That day, he just spent a million credits to get into the Immortal Rank Training Room, and I even laughed at him for showing off!"

"Half a month...he actually stayed inside for half a month?!"

"..."

The students in the hall all felt their scalps tingle, an indescribable sense of horror shooting straight from the soles of their feet to the top of their heads.

It's important to know that the mental energy consumption in the skill practice room is determined by the skill level.

The lowest level of character training room has twice the environmental resistance of the outside world, and ordinary students will become mentally exhausted after staying there for three or four hours.

Even if you can rest inside, a short rest is not enough to fully recover.

The highest-level immortal-grade training room has an environmental resistance ten times that of the outside world!

Under such high pressure, even the top students from previous schools could only last a day and a night before being forcibly kicked out by the system due to mental exhaustion.

An ordinary person can spend a day in the character practice room and then post on the school forum to brag about being a hardcore gamer.

But this guy actually managed to stay in the Immortal Rank training room with ten times the resistance for fifteen days!

"How much mental energy must that take..."

The crew-cut boy swallowed hard. "Is his brain made of titanium alloy?"

"Impossible! Absolutely impossible!"

The tall, thin man shook his head frantically. "It must be a bug! Or maybe he just lay down and slept after going in, without practicing his skills at all!"

"Are you an idiot?! Is the AI ​​in the Immortal Rank Training Room just for show? If you don't cast spells at high intensity as it demands, it can electrocute you within five minutes!"

"Then he..."

The students looked at each other, and a terrifying thought simultaneously surfaced in their minds.

This guy, enduring ten times the mental resistance, and under the torment of that freakish artificial intelligence, cast spells at high intensity for a full half month?!

Is this even human?
