Lin Mo transmigrates to the world of immortal cultivation with four spiritual roots from the start. He's such a good-for-nothing that he barely passes the Qingxuan Sect's outer-sect examination, leaving him with no choice but to work as a menial in the medicine garden.
Luckily, he carries an old copper fragment close to his body. It doesn't give him cultivation techniques or boost his cultivation. It only grows hot to warn him of danger when he's near heavenly treasures, dangerous restrictions, or a deadly ambush, with the heat corresponding to the level of danger.
In an age of great strife, the strong prey on the weak. Sects scheme against one another, rogue cultivators clash, secret realms bristle with danger, and great calamities threaten the world. Everyone is scrambling to climb higher. Lin Mo just wants to stay alive.
He never gambles on long-shot opportunities or makes deals he can't be sure of. He always keeps a backup plan and an escape route. While his fellow disciples fight over a magic treasure, he has already dug out a cave dwelling deep in the wilderness. While ten thousand cultivators are reduced to ashes beneath the lightning tribulation, he watches the sun, moon, and stars slowly rise in his own little world.
After avoiding calamities for two thousand years, he rises step by step from a menial to a tribulation transcender, ultimately opening up an independent little world and becoming the immortal of legend whom no one can ever find.
