Yun Che picked up a child full of demonic energy in the snow and named him Ajin. Neither his status as a demon nor the evil spirit filling his meridians could stop the golden elixir germ deep in his Dantian that refused to be extinguished. He accepted him as his disciple, taught him swordsmanship, and protected him from wind and rain for three hundred years - but he never saw the other kind of heat hidden in those clean eyes.
It wasn't until the Demon Killing Order was nailed on the door lintel, and the apprentice covered in demon marks grasped his sleeves and asked: "Since you know that I am a demon, why do you still keep me?" Yun Che suddenly understood that the morning tea and night shadows for the past three hundred years were all a knock on the door that he had waited for too long.
Intention: Love is a silent knock on the door. Some people have been knocking for three hundred years, and some have been deaf for three hundred years. Fortunately, after the snow melted, the flattened grass marks under the wall were still there, and the golden elixir germ deep in the Dantian was still there. The door finally opened from the inside.
