Quick Transmigration: I Save a Mad Young Lord God with My Frail Health

[Quick transmigration + two male leads + 1v1 + sweet romance + equally powerful and devoted]

Cool, aloof, and lazy former Supreme God, Shenyu (the recipient) VS two-faced younger current Supreme God, Zhaohuai (the pursuer)

Shenyu gathered a billion years of spiritual energy and transformed into a god. With nothing to do, he loved traveling through small worlds. But after one trip, he came home with a child he'd picked up.

The child was always meek and well-behaved around Shenyu, but at other times he was like a fierce little wolf.

Someone once asked Shenyu, “There are so many people in the mortal realm. Why did you pick him up in particular?”

Shenyu waved a hand and smiled. “He has the makings of an immortal.”

But Zhaohuai knew it was a moment of compassion on Shenyu's part, as well as his dissatisfaction with the Heavenly Dao.

Shenyu spent a hundred years raising the little wolf he'd brought home, and the boy didn't disappoint him. His power grew at an astonishing rate: in just a century, he reached what would take others a thousand years to attain.

So Shenyu naturally passed the position of Supreme God to him, freeing himself to go back to being a lazy layabout.

But to his surprise, the first thing Zhaohuai did after taking the throne was split his own soul and send the fragments into three thousand small worlds.

Shenyu was furious, but still had to go retrieve the pieces of Zhaohuai's soul and put them back together.

Zhaohuai used himself as bait, all to win Shenyu's heart.

Zhaohuai across countless worlds:

At first: This sickly guy looks like a bit of a handful...

After being won over: I love you. Don't leave me.

(There is an age gap. The recipient is powerful and dotes on the pursuer.)

The first world involves wcn, so it's very likely the story went off the rails, and the logic is rather messy too. If that bothers you, feel free to skip straight to the second world after finishing the first part.
