The Rebellious Son Causes Trouble Every Day, and Li Er Begs Me to Take the Throne

After transmigrating to the Tang Dynasty, Li Chengsi becomes the crippled eldest legitimate son and binds the [Strongest Rebellious Son System] and [Russian Goods Space] from the start.

As long as he drives people absolutely nuts, he can rack up debt to exchange for miraculous medicines, and trade copper coins for Soviet weapons!

In the Taiji Hall, Li Chengsi publicly renounces his position as crown prince and smashes his head against a pillar. "Erlang! You old geezer! Whoever wants this lousy crown prince title can have it. I'm done serving you!"

Li Shimin roars with fury. "You unfilial brat! Without me, you'll freeze or starve to death on your estate!"

But then everything spirals completely out of control...

Li Chengsi presents a bottle of fast-acting heart-saving pills. Empress Zhangsun says, "Erlang, Chengsi is being filial. Don't make a scene!"

Li Chengsi presents vodka and a giant iron pot. The Retired Emperor Li Yuan says, "This grandson of mine is ten thousand times more sensible than Erlang!"

Cheng Yaojin lounges around at Li Manor every day, mooching off their Simmons mattress, while Wei Zheng spends three days camping outside the estate, waiting for the heated kang designs.

Then the aristocratic clans join forces to attack Li Manor...

With a cigarette dangling from his lips, Li Chengsi pulls back the bolt. Two hundred death-defying soldiers in bulletproof vests, armed with PPSh submachine guns, pour out in full force!

Li Shimin is so terrified he collapses on the spot. "You unfilial brat! You've been courting death every day, but secretly you hand-built an iron torrent of an army?!"
