[Slow-burn Farming], [Apocalyptic Infrastructure], [Trait Fusion], [Road to Immortality], [Dawn of Evolution] weren't instant destruction, but the beginning of a frenzied evolution of global life. Civilization collapsed, and the world became a hunting ground for the weak. A month before the catastrophe, Gu Cheng unexpectedly awakened the power of [Trait Extraction and Infusion]. He could glimpse fragments of the laws underlying all things—[Hardness], [Sharpness], [Rapid Healing], and even [Fuzzy Insight]. With the foresight he extracted from crystals, he glimpsed a bloody future and gained a week's advantage. There was no passionate struggle for supremacy, only extreme planning and cold determination. He chose a more difficult path: slowly but steadily building a doomsday fortress in pursuit of eternal life. He strengthened himself, prioritizing wisdom and perception; equipped himself with equipment, giving his bow, crossbow, and armor unique characteristics; built a base, and...

After transmigrating, Xu Zhengyang arrived in the world of cultivation… with a programming-based physique.

While others were still sitting cross-legged, tediously absorbing spiritual energy through meditation,

Xu Zhengyang had already written a script that allowed him to cultivate automatically 24/7 without rest!

While others spent day after day painstakingly practicing spells, hoping to gain a slight edge in combat,

Xu Zhengyang had not only packaged spellcasting into executable modules that could be instantly triggered with a single click,

but had also developed customizable spell combos!

And that was just the beginning.

He developed mathematical tools to optimize formation arrays,

used programming logic to crack seals and restrictions,

reverse-engineered alchemy recipes,

built firewalls to resist soul possession,

ran antivirus programs to eliminate inner demons,

and applied algorithmic optimization to control puppet armies…

Years later,

Xu Zhengyang had already become a giant of the immortal path.

Looking back on his journey,

he smiled and said—

“Code is law. Trajectories are the Dao.”

Reborn as a mosquito? A system where you become stronger by sucking blood?

Chu Sheng was a little silent about this opening.

I've turned into a mosquito, how strong can I become?

But anyway, I have to give it a try...

Chu Sheng randomly flew into a room, and unexpectedly there was a gorgeous girl inside.

Good! Just suck her!

…

Gu Yuexi, an emperor-level beastmaster and empress of the human race!

In her previous life, she didn’t start the beast taming journey until she was sixty years old, and the first beast she contracted was only of low-level bloodline, which led to an unstable foundation and its death in the heavenly calamity.

When she was reborn at the age of eighteen, she must become a beastmaster as soon as possible!

She spent all her money to buy a demon beast with high-level bloodline and prepared the blood contract ceremony!

Just as she was about to sign a blood pact with the monster, a mosquito flew onto her leg and sucked a mouthful of her blood!

“…”

"My name is Gu Yuexi. I seem to be useless in this life..."
