**Human Emperor Banner:** The natal treasure/system carrier of the protagonist Xiao Ming. Core functions:
* **Soul Refining:** After killing an enemy (especially a strong one), his soul can be sucked into the flag for refining, and transformed into the purest cultivation, vitality, law understanding, etc., Which can be directly absorbed without side effects. It is the core way for the protagonist to quickly upgrade.
* **"Elegant Seat" Space:** There is a special space inside the banner. The soul that is sucked in will be imprisoned in it and endure the endless pain of soul refining. At the same time, its "existence" itself will be transformed into nourishment to strengthen the Human Emperor Banner. The stronger the soul and the deeper the resentment, the stronger the strengthening effect on the flag. The protagonist can control the perception of the soul within the banner to a limited extent (allowing them to "see" the outside world or endure certain tortures).
* **Growthability:** The more and stronger souls are swallowed, the stronger the power of the Human Emperor Banner (attack, defense, assistance), the larger the space, and even new abilities can be derived (such as soul torture, curses, summoning banner souls for combat, etc.).
* **Symbolic meaning:** The external manifestation of the protagonist's "superhero" character is a deterrent, a judgment, and a source of strength. Its growth is accompanied by the protagonist's killings and psychological journey.
