You Won't Make Me Crown Prince? Father, Please Abdicate!

(Alternate history + consorts + System + historical warfare, from the Shang Dynasty to the early Qing.)

Chu Ge was reborn into the imperial family. Not long after his birth, someone poisoned him. After he finally grew up, he was targeted again.

His imperial consort mother was murdered, and he himself was banished to the frontier.

Then he understood: in this world, in the imperial family, kindness was useless.

He hated the emperor and the harem. He swore he would fight his way back.

To avenge himself, he waged war across the land. In the end, he amassed an army of 300,000, marched straight into the palace, overthrew it, and ascended the throne.

At the same time, he activated the System, which could connect him with emperors from different dynasties.

Target for borrowing troops: Emperor Huizong of Song

Number of troops requested: The more, the better

Victory reward: Six Jia Soldiers

System enhancement: Converts the troops under his command into Six Jia Soldiers, who fear neither death nor pain.

Drawback: They cannot wear armor.

Emperor Huizong of Song's fee: 500,000 taels of silver and 10,000 taels of gold.

"You owe me ten billion, and this is all you're offering? No deal! Get lost!"

"What? You want to borrow troops to fight Li Zicheng? No money? That's fine. Just agree to let me loot the rich and powerful in the capital for three days, and I'll wipe out Li Zicheng's forces for you."

"You want to borrow troops to fight Liu Xiu? That's a bit pricey! You have money? Then no problem. Pay up and the troops are yours."

The protagonist will wage war across different dynasties as a mercenary.
