Shinwa Densetsu no Eiyuu no Isekaitan - Volume 1, Prologue

Su Qin crosses into a world where martial artists run rampant, where Buddhist monks from the Yuan Dynasty dominate the world. Jiuyang’s successor’s fist conquered the mountains and rivers, and Xiao Li’s flying knife smashed through the void.

Because Su Qin had no martial arts qualifications, he could only become a sweeping monk in the Shaolin Temple. At this time, the ‘Sign In System’ was activated.

Sign In in front of Buddha’s Golden Body, get [Buddha’s Palm].

Sign In in front of the Arhat Hall, get [Invincible Vajra Divine Art].

Sign in at the back mountain of Shaolin Temple, get [Golden Demon Body].

The Shaolin Temple was riddled with treasures, and you can sign in everywhere.

Su Qin decided that he would never leave the mountain without Signing In to everything in the Shaolin Temple. And so, he Signed In the Shaolin Temple for twenty whole years!

Twenty years later, the Shaolin Temple got mixed in the battle between the Righteous and Evil.

The Demons were fierce and powerful, they blatantly invaded the Shaolin Temple and were pushing forth with great force, but that is until they met Su Qin who was sweeping the floor…

Before death Qin Tailong left two magic tools to his son, Qin Dong. In his father’s last words, Qin Dong realized his father had been murdered by Lord Wanpeng, who coveted one of the family magic tools—mystic chaos ring. Bearing the hatred in mind, Qin Dong swore to revenge against his foe. He escaped to the mortal realm temporarily, continued to strengthen his cultivation base and studied the secret hidden in the seals of the ring. While reveling the secret, he found five ladies were the key to the release the seals. Their romantic relationship with Qin Dong was established the moment he was born.
