Seirei Tsukai no Blade Dance - Volume 16, Chapter 11 - Ghosts of the Demon Capital

Rael, once a teenager crippled by social anxiety, is reincarnated 1,553 years into the future after reading a book about Milford, the legendary God of Machima—a man who commanded armies of Steelborn, Machnoids, and Autonoms across the universe. Gifted with the Machima Bloodline and guided by Dominica, the World Domination System, Rael quickly rises to become the strongest World Conqueror.He first saw them on the book’s cover—steel women with lifelike faces, beasts with razor limbs, and looming above them all, a god in robes with a mechanical hand raised high. Coiled over him were a gigantic centipede and serpent of metal, guardians of his legend. Now, deep in a junkyard centuries later, Rael forges his own path. His first creation: an unbreakable fortress born in the dirt, a hulking Steelborn Tortoise with a mind sharper than any AI—crafted by Rael’s divine talent. From admiring Milford and wishing to be like him, Rael now marches forward to leave his own mark on the universe.Join him as he rises in rank across his world—and beyond.

Li Xuan traveled through the world of immortality and opened the apprentice system, and both apprentices and apprentices could be rewarded for upgrading.

【Ding! Accepting apprentice Qin Yue, reward you: Innate Divine Power]

【Ding! Accept the apprentice Zhao Tian, ​​reward you: call the wind and call the rain]

【Ding! Apprentice upgrade, reward you: space shuttle]

….

Li Xuan, who accepted a bunch of apprentices, evolved infinitely in seclusion.

Ten years later, the Devil Emperor invaded and wanted to sacrifice the whole world, but no one could stop it. The disciples watched the world fall into despair in pain.

At this time, Li Xuan appeared and slashed a sword against the Demon Emperor under the watchful eyes of the public.

Boom!

The sky fell apart, the invincible Demon Emperor fell on the spot, and the entire dark world was swept away by a sword.

The disciples were horrified. It turned out that the strongest person in the world was actually the master who had been in seclusion for ten years.
