[Three Kingdoms] Adou's Genius System

My name is Liu Shan, and my childhood name is A Dou. Shan is the “Shan” in the Mount Tai fengshan rite, and Dou is the “Dou” in the Big Dipper. I'm a bona fide genius, no air quotes needed.

The year I was born, I gave everyone a little shock from a heaven-chosen child.

The Big Dipper shone brightly, and the Ziwei Star descended from the sky into the birthing room. Liu Bei and the others: !!!

System, the Ziwei Star in Liu Bei and the others' eyes, with a slight landing mishap: ...

Though the opening had a few minor hiccups, the System believed that with its help, both it and its Host would have a bright future.

But if Liu, Guan, and Zhang were waiting outside, and Lady Gan was giving birth inside, why was the birth taking place in Xiaopei, Xuzhou?

The System was a little confused.

The System was full of doubts.

The System watched and spoiled what was coming.

The System witnessed its Host perform the fengshan rite at Mount Tai.

--Please note--

1. This is a feel-good, ensemble-cast story set in an alternate parallel world. The protagonist is the genuinely brilliant A Dou, born earlier than his historical counterpart. Some other characters were also born at different times than in real history.

2. The story mixes historical records with Romance of the Three Kingdoms and some unofficial histories. Forms of address and dialogue don't strictly follow Han dynasty conventions; you'll see words like “you” and “I.”

3. The blurb is in first person; the story itself is in third person.

Theme: I decide my own fate.
