Lin Yan had transmigrated into the world of Immortals and had become a Heavenly Emperor who was already defeated by the Male Lead along with the ten Female Leads at the beginning of the plot.

But as Lin Yan was about to die, he awakened a power that he could use to rewrite his past doings.

So, Lin Yan has begun to rewrite his past.

When Lin Yan was still a child, he struggled to feed Xiao Yanran, one of the female leads, who was then younger than him. He had to strip his Supreme Bone and give it to her, protect her from the obstacles. He made a vow, “As long as I am here, no one will be allowed to bully you.”

Later when Lin Yan’s cultivation rose , he had run into Xiao Mei, yet another heroine, and the two of them spent time together and eventually got married. When the Devils were about to invade their world, Lin Yan said staring right into his wife’s eyes, “I will protect you with my life…”

And soon he rose to become the Heavenly Emperor.

Everything he did was to shelter his loved ones and to protect the world.

However, his actions were misunderstood by the world.

…

Let’s see what all Lin Yan had done in the past…

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!
