Long Aotian, the youngest Emperor Venerable on the Myriad Worlds Continent, has spent years unable to break through to the final Divine Realm.
Unable to stand it any longer, the System within him unleashes all its power and sends Long Aotian back to the Myriad Worlds Continent ten thousand years in the past, hoping he can make up for his regrets and break through to the final Divine Realm.
Unfortunately, things don't go according to plan. On the very day Long Aotian successfully returns to the Myriad Worlds Continent ten thousand years in the past, he accidentally kills the fiancée he has cherished in his heart for ten thousand years...
"Brother Aotian, look at my white dress, stained red with blood. Doesn't it look like a bright red wedding gown?"
"Brother Aotian, I really wanted to be your wife and spend my whole life by your side. It's a shame... you and I were never meant to be..."
"Though our story didn't have a perfect ending, I've never regretted meeting you, Brother Aotian!"
Big cheers for the author
