I Offer You Mountains and Rivers as My Betrothal Gift

The famous Tianqing Sect was wiped out in a single night. Well, good riddance. The sect was notorious and loathed by all anyway. Ling Tong had been called down the mountain early that morning by a little flower spirit, and there he met one of the last two surviving disciples of the Tianqing Sect: Gu Ran, the shamelessest person he'd ever encountered. Gu Ran, for his part, met the coldest and strangest-tempered person he'd ever encountered: Ling Tong. Gu Ran also learned that this odd-tempered brat was the legendary master from the Lingyu Cave, who regarded the Ling clan as his enemy! Ling Tong watched Gu Ran laugh and joke after falling under a flower spirit's bewitching spell, laugh and joke after being poisoned by a corpse king, and laugh and joke after being beaten black and blue by the Demon Sect's Ghost Gate Master. Even after his sect was destroyed, he probably laughed and joked... The only time he didn't was when another “Gu Ran” appeared: a powerful man with a face like a demon, who killed without batting an eye... Gu Ran watched Ling Tong stay cold and expressionless as he tore through all manner of demons and monsters. Even when a mortal died in front of him, he could only look on coldly... Until one day, Gu Ran heard a heart-wrenching cry that changed his view of Ling Tong. So he could be fragile and helpless after all? After one pursuer receives a reward from the Celestial Realm, he tells Ling Tong, “I have nothing else to offer, so I'll give you the mountains and rivers I just received as your bride price...” A noble, aloof, celibate recipient × a passionate pursuer with a split personality. PS: Recipient-focused, happy ending. Revenge, monster-slaying, memories, and the present.
