"If you think it's okay, you're welcome to stay..." Lin Ke smiled and said, "Our Great Wilderness City embraces all philosophical schools. As long as you don't interfere with others and abide by the laws, you're welcome... By the way, we also have an Idealist School research institute, although we currently lack a leading scholar."
The Insomnia Emperor dissolved the institute before, and many schools were absorbed by other forces.
Great Wilderness City also absorbed many people from the Black and White Research Institute back then, including many from the Idealist School.
