After Gu Xijiu kept the contract, she walked away with the mussel. The mussel had eaten so much till it could not close its shells. It transformed into a smaller size to help it move around.
It was very excited and planned for the future on their way back, "Master, you should grab more opportunities to let him treat us. I think he is quite generous. This is the first time I have eaten so satisfyingly."
Gu Xijiu remained silent. She felt at this stage that it was more difficult to ask Yan Chen to buy them a meal than to fly to the moon.
She also felt a bit guilty when she recalled the moment when Yan Chen had insufficient money to pay for the dinner. It seemed like she had spent too much of his money this time.
This was a massive lesson for Yan Chen. In the future, he would surely mention beforehand that he would only be buying food for the humans and not the mussel.
