My Weekly Refreshing Mentor Spirit

After the completion of his college entrance examination, Xue Dili finds that within his body every week will randomly spawn a Mentor Spirit with great achievements— In the first week, an Undead Demon is spawned, what does it mean to be a villain with innumerable crimes? In the second week, a Great Sage is spawned, what does it mean to be a deserter who escaped alone? In the third week, a Hero is spawned, what does it mean to be a reckless and aggressive waste? ...... Do you have some misunderstanding about “great achievements”? All the spawned Mentor Spirits have major issues!
