I've Become a Genius Actor - Chapter 56:

In a certain empire, a young prince was born with a golden pickaxe. It should have been seen as a miracle or a blessing, but instead, the emperor wanted nothing to do with the child. He refused to accept a prince blessed with what he considered a commoner’s job, fearing it would taint his royal bloodline.Abandoned by his own parents, the young boy, Shennong, was taken in by a succubus.But neither the succubus nor the emperor knew the truth about him—Shennong was no ordinary child. He was a reincarnator.This is the story of how the world of Matay reacts to the birth of the first Sandboxer, a class unknown to many. Will Shennong forgive those who abandoned him? What was the purpose of his reincarnation in this world? What is the true nature of the golden pickaxe, and what does it mean for Shennong?One thing is certain—Shennong is not alone in this world because he had a true sandbox system and people to support him even in this world.Join him and experience a true sandbox adventure!

I had a supporting role in a modern fantasy.

The loyal dog of a villain with an angel’s name, Cheon Sa-yeon, and an unfortunate supporting character who died on his behalf, Han Yi-gyeol.

In order to escape from Cheon Sa-yeon and survive, he must use the protagonist, Ha Tae-heon.

But Ha Tae-heon, who he thought of as a lifeline, was infinitely indifferent to him. Rather, Cheon Sa-yeon showed interest.

But besides that, something strange happened.

The events that occurred in the original story had advanced, and the gate and monster levels had risen. Even the people were “different” from the original.

The original version I was trying to use was wrong.

Twelve zodiac animals represented the months of the Lunar calendar. No one was aware,however, that these twelve representations were Guardian Gods. These twelve positions were passed down the twelve patron bloodlines. They possessed the ability of the zodiac guardians and silently protected the East.

In the East, the auspicious Qilin, possessing royal blood, descended, reigning over the Twelve Zodiac Guardian Gods, who devote all of their power into protecting the East.

A ruffian Qilin, an Earth that transcends all expectations, a legendary city, and the patronage of the Zodiac animals together create an unforgettable novel.
