This novel is also known as I Possessed a Demon Sovereign

Chen Luoyang felt that something was wrong with his transmigration. After transmigrating, he possessed the body of the highest expert in the world, the Master of the Demon Cult, addressed respectfully as the Demon Sovereign.

Generally, aren’t supreme experts the ones that leave behind a wisp of their soul behind and occupy a new body of some miserable low-level youngster then they go on a journey of revenge and make a comeback?!

Or perhaps it would be transmigrating into a miserable youngster’s body and obtaining a cheat slowly walking the road to becoming a God?

But why did his transmigration seem wrong?

Now my environment is full of big shots and I feel like I’m going to be exposed!

When you grow up, you’re mine.

Lu Feng, with her fiery character and short temper, only had one fatal weakness. That was the lukewarm and soft Xu Mu.

There were so many youths in the capital, yet she took fancy to none of them. She instead sought after her newly arrived neighbor’s sweetie and secretly planned to kidnap him home.

Until one day, the two became cousins…

Lu Feng: … That nutrient-rich water cannot flow into someone else’s field!

Xu Mu: =v=

~~~

Xu Mu: What am I to you?

Lu Feng: You are my sweetest candied fruit!

~~~

In their previous life, Xu Mu and Lu Feng were married for only half a year when she died in battle. Xu Mu couldn’t bear the news of her death and followed her three days later.

Who knew that after he died, time flowed backward and returned him to their childhood. Xu Mu sat on his bed, dazed. In this life, he needed to think of a way to first find his wife, then chase her with all his strength. Only until he made up their past life to her would he “leave”.

Xu Mu: Last life, I didn’t love you enough. This life, I want to love you even more. Starting from innocent little childhood friends to the grey-haired and weak elderly, I will not let you go.
