Capítulo 555: Zi Yi’s Self-Made Thermal Generator

Zhang Hanyu did not manage to get in touch with Dou Xiangling for an entire day and he suddenly felt a little uneasy. He decided to make a trip to the School of Science and Technology to look for Professor Dou Zhiyuan.

However, when he arrived downstairs at the dormitory lobby, he saw a courier.

There were mailboxes right outside the dormitory staircase and Zhang Hanyu subconsciously took a look. He noticed that the courier was opening the mailbox for 505 and so, he walked over. "I am the resident of 505, you can pass me the package."

As soon as the courier heard what he said, he turned around and passed the package to Zhang Hanyu before he took his leave.

Zhang Hanyu looked at the courier envelope in his hand. He originally wanted to check who the sender was, but only to discover that there was only the recipient's address written on the envelope. There was no sender's address.
