[Two male leads + strong leads + shou's perspective + devoted to each other, no angst]
Shen Zhaonan was a peerless genius, born with a pure Yang body and a natural sword bone. He was undisputedly the top disciple of the Nine Heavens Immortal Sect and the foremost among the younger generation of cultivators. Yet an accident in a secret realm sent him transmigrating to another world.
Snow Yai was an ancient wielder of the laws of nature. Unable to control his own power, he had imprisoned himself. He slept for ten thousand years, until a young man bearing a sword barged in.
Shen Zhaonan had three goals:
1. Win the championship and use the “Mirror of the Void” to return to the cultivation world.
2. Train hard and reach Snow's level as soon as possible.
3. Bring this dragon back to the cultivation world.
Sword cultivator powerhouse shou × world-ending dragon gong
They're both incredibly strong. The gong has always been at the very top in terms of power, and the shou eventually becomes one of the strongest as well. (A growth-oriented, overpowered hero.)
It's very interesting to watch. The subject matter is also very novel among the two male protagonists. The relationship between the two develops smoothly. I highly recommend it.
