The Three Kingdoms: The entire Cao Cao camp thought I was weak and frail.

[Three Kingdoms + System + Time Travel + Strategist + Two Male Leads]
Transmigrating into the body of the sickly first man of the Three Kingdoms, Xun Hao activates the [Legacy of Strategies] system at the start, possessing flawless plans, but at the cost of burning his life force! To survive, Xun Hao sets his sights on the doomed genius Guo Jia—he is my only "human power bank"!
So he put away his scheming and pretended to be an innocent and pitiful person who idolized him and clung to him.
"Brother Fengxiao, my hands are so cold, may I hold them?"
"Brother Fengxiao, I feel dizzy. Can I lean against you for a while?"
Every touch is a way to secretly "absorb electricity" to prolong its life!
They were the most compatible partners in Cao Cao's camp.
One remotely controls the battlefield from behind his sickbed, winning battles effortlessly; the other orchestrates events from the front lines, reducing enemy forces to ashes with a mere flick of the wrist.
Together, they rescued Dian Wei at Wancheng, burned Wuchao at Guandu, plotted against Lü Bu in Xuzhou, and overturned the Battle of Red Cliffs! They ended the Three Kingdoms period as soon as possible and nipped the Five Barbarian Invasions in the bud.
