Lord Wu Zhu was a mysterious character in " Celebrating Years." He was the servant of the main character, Fan Xian's mother, Ye Qingmei. He possessed unfathomable martial arts and was known as the Hidden Great Grandmaster. His strength surpassed the Four Great Grandmasters. Wu Zhu was an intelligent robot left behind by a highly developed high-tech civilization. He was brought out of the temple by Ye Qingmei to become her servant and protector. His true identity was the first generation of the Immortal Messenger sent by the Temple to the human world.

The world structure of " Celebrating Years " was after the extinction of mankind, the Earth fell into nuclear radiation, and civilization regressed to prehistoric times. The surviving humans were divided into three parts, two of which went to other planets, and the remaining part built a nuclear radiation protection " temple " in the Arctic Military Museum. After thousands of years of development, humans were reborn and gradually adapted to nuclear radiation. The temple sent oracles to teach humans farming, irrigation, martial arts, and so on. Humans gradually developed into a feudal society. However, the temple stopped transmitting knowledge of civilization to humans and stopped the progress of human civilization. This was because the temple believed that according to the development of the established civilization, a nuclear war would eventually break out and lead to the destruction of mankind. This process lasted for a thousand years until Ye Qingmei escaped from the temple and brought civilization technology. Only then did civilization begin to develop again. Therefore, the world structure of " Celebrating Years " was the story of reconstruction and civilization development after the nuclear disaster.
