Transmigrated into a marquis's son-in-law, I started by obtaining the Dragon Elephant Skill.

Summary The heavens cleaved open, and celestial treasures descended upon the land, transforming the world. Divine physiognomists, with their iron will, could foresee the rise and fall of dynasties. Sword immortals wielded their swords across vast distances, slaying enemies without a trace. Living Buddhas, indestructible as steel, could crush ten thousand mountains with a single palm strike. Demons ravaged the land, sacrificing entire cities in blood to break through the mystical barrier. Gu Qingxuan transmigrated, becoming a son-in-law in the Dingyuan Marquis's household, less than a servant. His wife indulged in nightly revelry and kept male lovers, while he was beaten half to death, awaiting his final breath. In his moment of crisis, he awakened the [Mountain and Sea Mystic Mirror], capable of piercing through illusions and appraising all things. From then on, the world gained a monster with godlike treasure-hunting abilities. What others bought for fortunes, he instantly recognized as junk. What others discarded like worn-out shoes, he found to be dusty, divine artifacts. He amassed treasures until his hands were sore, and cultivated until he ascended to immortality. From then on, he suppressed demons, subdued alien races, and executed treacherous villains, wielding immense power and becoming invincible in the world. "All the treasures of the world are in my grasp, and the storms of the eight directions are but a matter of the palm of my hand."
