[Alternate History of the Early Qing Dynasty] + [Domestic Intrigue and Entertainment] + [Historical Power Struggles] + [Intelligent Thinking] + [Decisive and Ruthless]
He transmigrates into the body of Jia Jing, the illegitimate son of the Rongguo Mansion in the Dream of the Red Chamber.
Was Jia She, the biological father, only a drunkard and fond of his concubines? Was the second wife in charge? Was Lady Wang a wolf in sheep's clothing? Did the entire household revolve around Jia Baoyu? Did the sisters suffer tragic fates and perish? Was the Jia family doomed after their property was confiscated?
Fortunately, Jia Jing awakens the promotion reward system at the start, and he can get rewards as long as he gets promoted.
[Ding! Choosing the path to promotion for your general will reward you with Zhao Yun's martial prowess template!]
[Ding! You have been promoted to the eighth rank and gained five hundred Imperial Guards!]
[Ding! You have been promoted to the seventh rank and have acquired 1,500 Xuanjia soldiers!]
……
[Ding! You have been promoted to the rank of Qin King, surpassing even the highest rank, and have gained 10,000 Great Snow Dragon Riders!]
[Ding! You have been promoted to Emperor and gained a lifespan of five hundred years!]
He rectified family conduct, eliminated shady dealings, severely punished unruly servants, rebuked Grandmother Jia, slapped Lady Wang, beat Jia Baoyu, enforced military discipline within the family, and created a separate genealogy book!
He implemented new policies, eliminated traitors within the country, conquered barbarians without, sealed the wolf's lair, inscribed the Yanran Mountain, drank from the Mediterranean Sea, and controlled the sky with one hand!
With beauties like Lin Daiyu and Xue Baochai by my side, I have no regrets in this life!
Before he knew it, Jia Jing realized that he had reached the pinnacle of the world!
