On the Day I Resigned, I Unplugged Dynasty

I still remember that day, I suddenly woke up alone, and was surprised to find that I had traveled through time alone, becoming a powerful official with my own system, and used data to protect Dayan for ten years. The new emperor wants to use the last grain of rice to build the Jade Dragon, so I submit my resignation to unbind the system. The dynasty collapsed, and I lived in seclusion behind the scenes, put the generals I brought to the throne, and restarted a new kingdom.
