Due to an accident, young Zhong Xian was forced to enter into a destiny contract with the mysterious girl Suxue. At the cost of the disappearance of her "existence", he awakened the most powerful magical talent known as the "Blood of the Rising Sun". This power is not a blessing, but a curse marked with sin, making his magical path shrouded in mystery and bloody doubts from the beginning.
In order to pursue the truth, Zhong Xian traveled between the three major forces of Qingmingyuan, Xuanjihui and Lengyue Pavilion, and gradually uncovered the mystery of fate that entangled him: Suxue was actually the guardian of the ancient "border", and his tribe had been overthrown to seal the world-destroying disaster "Eclipse"; and the "Blood of the Rising Sun" he carried was the key to purifying "Eclipse" - the origin of life and creation "Primary Fire".
However, all forces are eyeing him. Black Thorn will regard it as a perfect research vessel and want to explore the nature of power; the "Order of Annihilation" intends to use him as a "vessel of the first fire" to welcome the coming of its master. Caught between light and darkness, Zhong Xian must control the mutually reinforcing forces within his body and deal with the multi-party game.
He not only wants to rescue the innocent creatures eroded by "eclipse" and recover the sleeping Suxue, but he also needs to face the truth of the original "sacrifice" and cut off the ancient grudges that entangle his fate. When the shadow of destruction comes again, can the young man burdened with sin use the blood-stained path of magic to rekindle the fire of hope to purify the world?
This is a legend that begins with sin and ends with redemption.
