The Immortal Overlord's Reincarnation

Jiang Chen's life was a tale of misfortune masked as luck. Adopted by the prestigious Luo family, he was seen as a fortunate orphan. 
Yet, behind closed doors, he was nothing more than a subservient servant, his life a series of endless commands.
his existence of passive obedience led him to an engagement with Luo 
Yiran, a bond not of love but of convenience.
His life of submission continued unchallenged until a grim diagnosis shattered his world. 
In a moment of unprecedented defiance, Jiang Chen made a choice that would change everything. 
Plummeting from the fifth floor of the hospital, he defied death and expectations, rising unscathed. But the Jiang Chen who stood up was not the man who had fallen.
He was now the vessel for the once Immortal Venerable, a being who had battled demons and roamed the immortal realms. 
This powerful soul had found a new home in the frail body of Jiang Chen.
Now, with the knowledge and might of the Immortal Venerable, Jiang Chen was equipped with everything he needed to ascend back to the Immortal World.
