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

"All Poisons Explode!"

Su Chen gritted his teeth and forced the sluggish magic circuit in his mind once again.

hum-

The surrounding space seemed to solidify into a tangible form, and the tenfold mental burden felt like an invisible mountain pressing down on his nerves.

Snapped!

A blinding blue arc of electricity exploded at Su Chen's feet, and the searing pain instantly jolted him awake.

"Too slow! Like a slug hibernating in a cesspool!"

Chu Ying, wearing high heels, cracked the barbed energy whip in her hand with a loud bang, her eyes behind her glasses flashing with a cold light.

"Spell casting animation exceeds 0.8 seconds, mana circuit construction deviation is 3.2%. Are you controlling mana with your toes? Or has your cerebral cortex been dissolved by your meager intelligence? Try again! Useless!"

Su Chen didn't retort; he didn't even have the extra energy to wipe the sweat that had slipped into his eyes.

Whoever planned this practice room must be a psychopath!

Su Chen cursed inwardly.

"All Poisons Explode!"

boom!

A cloud of ghastly green poisonous mist exploded from the black iron stake, which was immediately blasted apart.

however.

Before Su Chen could catch his breath, Chu Ying's cold voice rang out again.

"Skill form frozen, 15% of explosive power leaked out. Is this what you call success? If this were a battlefield, that attack of yours would not only have failed to kill the enemy, but would have also poisoned your stupid teammate as well."

"Zero points! Try again!"

Snapped!

Another whip lashed at Su Chen's feet.

Then, she summoned several more wooden stakes.

Su Chen took a deep breath and raised his hand again.

Time loses its meaning in this completely enclosed space.

Only one monotonous and tedious skill release after another.

Four hours later.

Su Chen's vision went black, his legs went weak, and he collapsed to the ground, panting heavily, feeling like his brain was about to boil.

"You've already collapsed?"

A pair of pointed high heels stopped in Su Chen's line of sight.

Hatsuyaki looked down at him from her high position, her eyes showing no pity, only dissatisfaction with the inferior product.

"It's been four hours and fifteen minutes since your last meal. Now, you have ten minutes to go to the dining area and consume some advanced nutritional fluids. Then head to the rest area; you only have five hours to sleep."

Hatsuyaki raised her wrist and checked the time. "If you are not standing in front of the wooden stake in five hours and ten minutes, I will activate the electric shock forced wake-up program."

Su Chen struggled to his feet and dragged his leaden legs toward the food court.

Sleeping only five hours a day?

Even the donkeys in the production team wouldn't dare to be used like that!

Even capitalists would weep upon seeing this work schedule!

Su Chen picked up a bottle of nutrient solution, tilted his head back, and gulped it down.

The cold liquid entering my stomach slightly relieved the burning pain in my brain.

He glanced at the luxurious leather bed in the rest area and collapsed onto it.

……

Over the next three days, Su Chen truly experienced what purgatory meant.

Strictly adhering to a 5-hour sleep schedule each day, with only a short ten-minute meal break, the remaining eighteen-plus hours are spent being relentlessly squeezed out of time while being held down in front of a wooden stake.

[Note: The release of the Poisonous Explosion failed.]

[Notification: The Poisonous Explosion has been successfully released.]

[Note: Progress of the Poisonous Explosion skill form reconstruction: 15%]

"The mana transfer node is broken! Are you an idiot? You can't even do the most basic mana distribution right, yet you want to change the underlying logic of the skill?"

"Angle! The angle is off by 2 degrees! Is your useless brain unable to even hold a three-dimensional coordinate system?"

"..."

Chu Ying's curses were the only sound Su Chen could hear during those three days.

She was like a cold and ruthless data monitor, accurately capturing every mistake Su Chen made, and then launching a comprehensive attack with the most vicious words.

On the fourth day.

Su Chen's eyes were bloodshot, and he looked like a teenager who had stayed up all night for several nights in a row.

However, his skill casting animations were no longer as slow and obscure as they had been at the beginning.

"All Poisons Explode!"

hum-

This time.

Instead of forcibly pushing with his immense mental power, Su Chen followed the texture of the tenfold resistance, found the weakest point in the flow of magic power, and then precisely cut in like a scalpel.

[Note: Thousand Poisons Explosion successfully released. Skill form reconstruction progress: 68%]

A cloud of dark green poisonous mist, several times denser than before, exploded silently inside the wooden stake, without leaking any power.

Hatsuyaki pushed up her glasses and, for the first time ever, didn't raise her whip.

"It can barely be considered a semi-finished product."

She gave a cold snort, her tone still full of disdain, "But it's just that it's upgraded from non-recyclable waste to recyclable waste."

"Don't get carried away. You're still a long way from evolving your single-target skill into an area-of-effect skill."

"..."

Hatsuyaki tapped the leather whip on the ground: "Continue. Solidify that magical circuit into your muscle memory. If you can't do it next time..."

She gave a very dangerous smile. "I'll punch out all the nutrient solution you just drank, along with your stomach acid."

Su Chen wiped the sweat from his forehead, a slightly manic smile tugging at the corners of his mouth.

After these few days of inhuman torture, he has completely adapted to Hatsuyaki's rhythm.

Su Chen's gaze became incredibly focused.

Under ten times the mental strain, each time he cast a spell, it was like performing a delicate surgical operation.

He was dissecting every rune and every loop of the [Ten Thousand Poisons Explosion].

He not only wants to make it passive, but also to add AOE (area of ​​effect) characteristics to it.

[Note: Progress of the Poisonous Explosion skill form reconstruction: 75%]

[Note: Progress of the Poisonous Explosion skill form reconstruction: 82%]

The fifth day has arrived.

Su Chen had not closed his eyes for thirty hours straight.

Chu Ying stood behind him, watching the data jumping on Su Chen's panel, the data stream behind her glasses flashing rapidly.

"All Poisons Explode!"

Su Chen let out a low growl.

This time, he did not reach out and point at the stake.

He forcibly severed the channeling loop for active skill release, forcefully channeling a massive amount of magic power back into his core class trait.

hum! ! !

The entire Immortal Rank training room suddenly trembled.
