The Wicked Supporting Lady System and Its Host Blunder Into a National Destiny World

(National Destiny + Two Male Leads + Devoted Couple + Cross-Dressing + Powerful Leads + Shou Protagonist + Mostly Everyday Life) Don't look, don't look. This one's a trap, can't hide it. My name is Chen Shuran, the perfect "vessel" in an ABO world. My own parents sent me to the operating table, altering my body to give me a chest no man should have, all to turn me into a suitable "mother." The day I escaped, the lab exploded like fireworks behind me. A wanted notice listing seventeen grave crimes covered the entire city, and under a hail of gunfire, a System with a little girl's voice bound itself to me... "Host!

The "007" of the ABO world, the "Prince Jing" of the ghost marriage scenario, and many more faces Chen Shuran has yet to meet. All their memories are shared, and every encounter is a game of chess they have laid out themselves. They intend to push Chen Shuran, step by step, to become a god
