The owner of the restaurant, with a heavy throat, said to Lucas, "can I please have a look at the letter?"
Lucas nodded his head, but instead of giving him the letter right away, he said to him, "I will give you the black box and all its contents. I haven't taken a single thing out of it. However, I need you to do something for it in exchange. If you agree to it, we can bind ourselves in a contract."
Lucas was well aware that saying this at this time was not a good idea, but he didn't have a choice. Because time was running out, he had to be cruel and do it.
The owner wiped off his tears and nodded his head. There was indeed no free lunch in this world, and he didn't blame Lucas for asking him such a thing. It was a fair trade, so to complete the transaction as soon as possible, the owner took out a contract made by a Half Emperor rank witch and signed it along with Lucas, binding them together.
