Stealing Energy In Another World

Hsu Fann, an average young man, finds himself in the mystical Realm of Eternity after a life-threatening incident. He has transmigrated into the body of a low-ranking disciple in a cultivation world, where he discovers a special ability: an energy-stealing system. This system lets Hsu steal energy, techniques, and resources from others, but only from those he has a connection with.  
The deeper the connection, the more he can take.  However, his ability quickly complicates his life, especially after he's spotted with Lin Qingyao, a skilled and beautiful fellow disciple, stirring up drama.
As Hsu leverages his ability to climb the ranks, his rapid rise attracts envy and admiration, placing him at the center of sect politics.  
With his power increasing, he faces the challenge of navigating his sect's intricate social web and the upcoming Sky Stairway Trial.  How will Hsu use his unique system to tackle these obstacles, and what unforeseen consequences will his actions bring?
