Feng Yun and Cheng Yu stayed in the cave for another three days. In these three days, they talk a lot about their personal things while cuddling on the bed.
"I am going." Cheng Yu said softly while embracing Feng Yun, "But I promised that I will return to you one day."
Cupping her face, Feng Yun kissed her on her forehead and said, "You know how to find me, if you encounter any danger then send me a signal through the sound transmission jade."
"I will." Cheng Yu nodded her head and smiled slightly. She was worried that Feng Yun would try to stop her or ask her the reason for leaving. But he didn't say anything, clearly understanding her thoughts.
"I have a gift for you, you will like them." Suddenly, Feng Yun remembered something and said. Releasing Cheng Yu from his arms, he took out an old iron chest from his space ring.
"What is it?" Cheng Yu asked curiously, Feng Yun smile, and indicated her to open the chest.
