In a large house in the north of Dingcheng, Zi Jin looked quietly at a letter placed on the round table in the middle of the room. The handwriting on the envelope was not familiar to Zi Jin. He sat quietly on the bed, as if he had just woken up, but also as if he had not slept all night. The letter remained motionless in Zi Jin's sight. Zijin suddenly smiled, the corners of his mouth raised slightly, and his eyes became clearer. He thought in his heart: Sooner or later, he would have to wait for this letter. He gently walked over and picked up the letter, opened it again, and gently opened the letter. Everything in the future lies in every word in this letter!
