Great Tang: The Rebellious Li Xiao, Starting by Making Li Er Furious

After transmigrating to the Zhenguan era, Li Xiao, the most arrogant son of Li Shimin, awakens the Rebellious Son System.

As long as his filial devotion turns rotten and he defies his father, he can unlock a modern nation's strategic reserve warehouse.

And so Li Xiao lets loose completely in the Great Tang.

Li Shimin: "Where's my Lady Wu? How did she end up working as your secretary at your estate?"

Li Xiao: "Father, she's my 'Great Tang partner.' Please show her some respect!"

Li Shimin: "You rebellious brat! You hung your brother Li Tai, Prince of Wei, from a tree and beat him. Is that what you call brotherly love?"

Li Xiao: "Father, you don't understand. This is called physical desensitization therapy. The Prince of Wei is much more obedient now. Don't believe me? Ask him."

Li Tai, Prince of Wei (bruised and swollen, with a fanatical look): "Father, don't interrupt. Big Brother and I are figuring out how to monopolize the aristocratic clans' steel trade!"

Watching the court officials become his son's 'underlings,' Li Er completely broke down: "I'm done being emperor! Please, just take the throne already!"
