Nancheng, 1934. Shu Yu crawls back from the abyss, with a woman named Bai Ruo now at his side.
Everyone says she is a medicine jar he keeps alive by showering her with mountains of gold and silver, his one and only weakness.
But they do not know that she is also his secret weapon, his blade, and the first ray of light to reach him in his darkest hour.
She stands by him through bloodshed and turmoil, while he shelters her beneath his wings.
Later, his weakness becomes his armor. What he wants to give her is no longer a mere transaction, but a lifetime.
