I Have a School of Guardians

Long Ling came to a parallel world. Others who traveled through time were either civil servants or simply invincible. When he came here, he had to build a college, train himself and students, and prevent the invasion of creatures from the mountains and seas. How could other people have such a good time? Why am I so tired when I get here? It's outrageous. What can I do if it's outrageous? It's my responsibility and there is nothing I can do. Since it has happened, then accept the explanation of my fate. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
