I Become the Emperor's Mentor in the Mortal Realm

He was once the Heavenly Emperor's teacher, revered across countless worlds. In one fateful moment, he was reborn as a good-for-nothing in the city. In this life, he will not cultivate the boundless power he wielded before. Instead, he will teach the people of this mortal world what it means to be truly supreme.

He doesn't cultivate power, but “understanding”:

The protagonist's soul is damaged from the start, leaving him unable to gather spiritual energy. But his golden finger is the “Emperor-Teacher's Eye.”

Read fate: See through anyone's fortune, flaws in their techniques, and fatal weak points.

· Teach the Way: He can't fight himself, but can instantly teach others how to fight. One lesson is worth ten years of painstaking cultivation.

· The Grand Game: Use heaven and earth as a board, mentally simulating a battle against enemies who won't appear for days, thousands of times in advance.

“In this life, I won't ascend through heaven's gate. In this life, I'll make immortals of the people of this world.”

· Appraising treasures: A great family spends ten billion on an “ancient artifact.” The protagonist glances at it. “It's a fake. The maker's mark is within three inches of the base.”

Medicine: A senior official declared beyond saving by Western doctors. The protagonist inserts a silver needle. “The spiritual energy is blocked. I just need to clear it.”

Martial arts: A grandmaster demonstrates his signature technique. The protagonist sighs. “Your wrist should turn thirty degrees farther on the ninth move. Your master didn't teach you the whole thing.”

He never lifts a finger himself. A few words of guidance are enough for a passerby to grasp the Way and kill the villain in return.

When a rich young master humiliates him, the protagonist turns to a waiter and says, “You were born with a swordsman's bones. I'll teach you a move. It'll be enough to beat him.”

When a campus beauty is haunted by a ghost, the protagonist says, “Your ancestors were demon hunters. Your bloodline has been sealed. I'll help you unlock it.”

Faced with a ten-thousand-year-old demon, the enemy laughs arrogantly. The protagonist looks at him calmly. “Didn't your master ever tell you that demonic energy can't pass through the Shanzhong acupoint?”

The demon freezes. Three breaths later, he shatters his own demonic cultivation on the spot, drops to his knees, and cries, “Grandmaster!”
