Why Cultivate Immortality? I Want to Be Invincible!

Yu Xingran, who worked overtime until late at night, fell asleep at his desk. When he woke up, he found himself lying in a garbage heap.

There were no phones here, no takeout, and even the air felt as heavy as water.

Old Zhao from the Mortal District told him, "Those with spiritual roots are chosen to cultivate immortality. Those without them rot away in the Mortal District for the rest of their lives."

Yu Xingran had no spiritual roots.

But he had brains: physics, mathematics, chemistry, and business acumen. In every field, he could crush the competition with knowledge from a higher dimension.

Starting by setting up a stall and writing for steamed buns, he used modern knowledge to demolish the cultivation world's "common sense": purifying pills with chemistry, designing formations with mathematical models, and using physics to face-slap the so-called geniuses.

When everyone said mortals could never cultivate immortality, he answered with data: "Spiritual energy has a concentration gradient. The body can adapt. Spiritual roots aren't the only way."

When Jiang Nian, the gifted apothecary from Medicine King Island, asked him, "You don't even have spiritual roots. How can you get stronger?"

Yu Xingran touched the two characters "Xiaoyu" engraved on the back of his watch and said, "There will always be a way."

He didn't just want to get stronger. He wanted to become invincible. Not to conquer anyone, but to protect those he cared about: his family in both worlds, the girlfriend who had waited for him for three years, and everyone willing to follow him.

This book has no System, no wise old mentor, and no sudden stroke of luck.

Just an ordinary person using his brains to carve out a path in the world of cultivation.

Why cultivate immortality? I want to be invincible.
