Master of Monster Synthesis - Chapter 3 Dragon War, Yimuki

Gu Yanfei was reborn. In her last life, it was only after her death that she realized she was the real daughter in a story about a real and a fake rich daughter. She was supposed to be the daughter of a nobleman, but someone switched her with another child at birth and left her leading a wretched life — a cannon fodder from start to finish. The female lead was the fake rich daughter, but she was also blessed with good fortune and the affection of the Gu family, taking everything that was rightfully Gu Yanfei’s.

In that life, Gu Yanfei lived as she died, with no rhyme or reason. However, after her death, she transmigrated to a cultivators’ realm and became a healer… But after cultivating herself for 200 years, she failed her ascension trials. Then, one of the divine thunderbolts struck her and sent her back to her last life — back to the moment when the identity of the rich daughter was exposed. Upon her return, everyone in the nobleman’s residence was laughing at her for being illiterate and uneducated, a far cry from the fake rich daughter blessed with good looks and a kind heart, who stood above the rest. They just did not know that Gu Yanfei was a fully-leveled character, reincarnated back to this moment!

How does it feel to lose your parents at the tender age of four?Imagine the trauma, the psychological scars. Now, take it a step further—what if they died right in front of you?That was Kael’s reality. As a young boy, he watched his parents perish while desperately protecting a golden coin.At the time, Kael had no idea of its significance. He only knew that their deaths were tied to it.Fleeing from his father’s murderers, he was forced to survive on the unforgiving streets, learning to fight, steal, and endure.Twelve years later, he had transformed into one of the deadliest assassins the world had ever known.He had no official title. No known employer. No traceable identity. Just a calling card.They called him The Coin Flipper.Not because he left his mark, but because after every kill—just as the body hit the ground, as the last breath escaped—he would flip a coin.No one knew why. Some believed it was mockery, a cruel reminder that fate had turned against them. Others thought it was ritual.But what they didn’t know was that each coin held power—literal currency of the Core System embedded in Kael’s soul.Every kill earned him millions. Digital fortunes funneled into off-grid accounts with each confirmed target. Blood turned into bounty, pain into profit.And one thing was certain: if you saw the glint of a coin spinning through the air, death had already found you.
