Seeing the other person remaining cautious, Shi Chun glared and said, "Why do you always have such a bias against me? How could I deceive you? We're exchanging Divine Fire, one bloom each. Once the real Divine Fire is absorbed into your body, can I even dig it out?"
Gu Lianni thought about it and indeed, that made sense. Alright, she agreed.
So, the two of them prepared pen, ink, paper, and inkstone on the spot and each wrote a letter.
Shi Chun finished writing first. He made a simple stone lock, which was just hollowing out a palm-sized stone, stuffing the letter in through a small hole, then sealing the hole, and marking it in a way that only he and Wu Jinliang would understand. Then he called over Chu Jingtang and Chen Wuji.
