After reading the letter, Zhang Yu saw that aside from inviting him to the Celestial Mechanism Institute, it contained little else, the rest being merely polite formalities.
Like the letters previously sent by the two prefectures, this one had likewise been sent in a private capacity. It bore the signature of the Celestial Mechanism Institute's current deputy director, Grand Craftsman Tan Cong.
