My cultivation disguise has been exposed by Xiao Sizi.

[Cultivation-based gameplay with overwhelming power + invincible and satisfying story + historical spoilers + Little Rhinoceros + No sycophancy towards Li Shimin]
For three years, Li Chen remained invisible in a side hall of the palace. His greatest pleasure was entertaining the little rhinoceros with low-level water ball techniques and wind control spells.
Until that day, the little girl cried and said that her mother was about to die.
The sixteenth prince of the Tang Dynasty took off his tattered clothes and put on a mask.
He appeared out of thin air as an old immortal with white hair, and with a casual gesture, the empress escaped death.
At the thank-you banquet in the Imperial Garden.
Fang Xuanling, deeply moved, bowed deeply and asked, "I beg the immortal master, what will become of the reputation of my Fang family for future generations?"
The old immortal looked at him strangely: "Your name will be remembered for eternity. Your son, Fang Yi'ai, will be crowned the King of Green Hats for all time. He'll personally move a small stool for your daughter-in-law and the bald monk to keep watch at the door."
Fang Xuanling coughed up blood and fainted on the spot.
Li Shimin's legs went weak, and he trembled with fear: "Immortal Master... what about my Crown Prince Chengqian?"
The old immortal casually tossed out an illusion array plate, in which the crown prince raised an army in rebellion, pointing at Li Shimin's nose and cursing the Xuanwu Gate Incident.
Li Shimin collapsed to the ground.
Just as the old immortal was about to leave, three-year-old Xiao Sizi stumbled out, grabbed the old immortal's clothes, and pulled an old sachet from his arms.
"Sixteenth Brother! How did you turn into an old man?"
Li Shimin: You unfilial son! How many things have you been hiding from me?!
Li Chen: Stop making noise, you're disturbing my teaching of Si Zi to read the *Lun Yu*. Confucius said: "If I hear the Way in the morning, I can die content in the evening." This means, if I know the way to your house in the morning, I'll go and kill you that evening.
Sizi: Difficult? Then let's not do it! (Flips the table, but can't move it). Sixteenth Brother, the table is too heavy, Sizi can't move it. What should we do?
