Slightly Serious Version of the Synopsis:

Lord Yunzhong, Feng Rugu, is a Daoist legend and the savior of the world.
At 14, he had a moment of enlightenment and created the Guixu Sword Technique with forty-nine forms, astonishing the world with his talent.
At 15, he mastered both magic and martial arts, forging the twin treasure swords, earning widespread admiration.
At 18, he fell into the demonic realm, protecting over a hundred disciples for eighty-nine days, shocking the world.
At 28, he retired to Fengling, living in seclusion by the quiet waters, settling into early retirement—only to be cruelly abandoned in an engagement breakup.

Not-So-Serious Version of the Synopsis:
Master Ruyi, a lone blade guarding the Buddha’s path, kills to protect the world.
The Western Buddhas are infinite in number, yet the only true Buddha in Ruyi’s heart is his adoptive father, master, and benefactor—Lord Duanrong, Chang Boning.
However, Chang Boning's care belongs solely to the junior brother he practically raised, Feng Rugu.
...It’s infuriating.
Tasked by Chang Boning to take care of his lazy junior disciple, who hasn’t left the mountain for ten years, the naturally aloof Master Ruyi hides his resentment well. Until one day, he discovers that Feng Rugu, just like his adoptive father, plays the konghou beautifully.
Ruyi, arms crossed: ...Lord Yunzhong, it seems Lord Duanrong has taught you well.
Feng Rugu: Heh. When you were young, you called me 'adoptive father'. Now that you’ve grown, you call me Lord Yunzhong.

Gong: Master Ruyi (You Hongchen) × Shou: Feng Rugu

A righteous yet wicked, beautiful Buddhist master (gong) × A carefree yet righteous Daoist wanderer (shou)

One-line summary:
"The world kissed me with pain, so I return it with pain."

1. Don’t ask if the gong is truly bald. If you ask, he is.
2. Main shou, younger top, 1V1, full of dramatic dogblood twists, with a charming gong and an irresistible shou. Five-year age gap.
3. The gong genuinely dislikes the shou at first for various reasons but will eventually have a change of heart—consider this your warning.
4. Multiple CPs warning.
