Master Damo was the first deity to have the guts to "try new things," what does that mean? In a nutshell, when Master Damo realized something was amiss, he quickly adjusted his mindset, made all the necessary preparations in advance, and came up with a new exit strategy for himself.
Master Damo, a man with a keen vision and ruthlessly cool demeanor, knew that the new way out for celestial beings was still in the Human World, so he started adapting to mortal life early on. After taking care of his official duties, he would always squeeze in some time to secretly descend to the Mortal World to experience life. It's fair to say, most of the modern gadgets in heaven today were scavenged by Master Damo himself.
