I, Rusilu Cullo, twenty-four years old, my biggest dream:

Live this life safely!

- Description from novelbuddy

Li Yuanqing transmigrated and became the crown prince of Northern Kingdom. He was sent to the borders, after his cultivation and meridans was crippled, because he refused to marry a princess and was not allowed back into the palace ever.

Just then, the Hundred-fold Sign-in System was activated!

Outside his house in the Wilderness, he signed in and received 100 Replenishment pills!

Beside the lake of the Wilderness, he signed in and received 100 Marrow Cleansing pills!

Among the warriors of Myriad City Kingdom, he signed in and received 100 Heavenly Skill manuals!

…

Li Yuanqing had thought that if he just signed in silently and received the hundred-fold reward, he would be able to watch over his younger sister until she became the ruler of the kingdom and until he became invincible.

But he had never thought that one day, the queen of Myriad City Kingdom would come to meet him!

“I am willing to use Myriad City as my dowry. Will you marry me, Your Highness?”

Li Yuanqing did not know what to do when he looked at the queen smiling beautifully before him…

Rakna was not normal. No, unmistakably not.

Whether it was his appearance, his personality, his abilities, his identity, nothing about him had ever been banal. Was it his choice?

No. He was merely but a tormented soul doing its utmost to live the life it had learned to never enjoy.

Would being picked by a glorified universal abductor calling itself a system bring something out of him?

Would he finally learn to breathe in the pool of blood that suffocated him? The Harvester does not sow, he only collects.

All he has ever known to feel was loss and the only thing he can do is take.

He will devour their hearts and drink their blood if it is what it takes.
