Li Changqing has just graduated from teacher's college. After a car accident, he transmigrates to the Great World of Jiuzhou and is bound to the Good Mentor System. By teaching and guiding his disciples, he earns rewards: as soon as a disciple masters a skill, Li Changqing receives that skill at maximum level, along with points. If the disciple continues to improve that skill, the Host keeps earning more points. Points can be exchanged for skills and items in the System Shop.
From then on, Li Changqing begins taking disciples in another world, witnessing every facet of human nature and changing countless lives along the way.
