Mask of Blue Legend

In Xuanyuan Continent, everyone living here has supernatural powers. Suddenly one day, a group of mysterious people quietly invaded. They were planning something. They sent people to investigate many times, but nothing was known, and they also lost human, financial and material resources. Feng Che and Lan Chen were childhood playmates (Feng Che's parents were internal affairs officials of the Xuanyuan Continent and were ordered to investigate the mysterious man's misfortune), and they were separated because of this. They disappeared without a trace, but they met again many years later. The suffering in their hearts was beyond words... "I don't have many friends, but you are one of them, and the most important one." "Whether it's you or anyone else, if I hurt him, I will never forgive myself. Just go!" "Feng Che, don't be like this, I've really been looking for you for a long time..." What happened to Fengche these years? What are those mysterious people going to do? What secret is hidden behind this? What is behind this?
