Descendants of Gibbous - Chapter 39: Rules

As a student, Lin Li suddenly owns a system and he expects it to be powerful enough to make his life better. However, unlike systems he has seen in novels, this system is so random.[Quest Triggered!][Quest One: Slay ten Little Demon Heaven Blood Crows that frequently attack and kill villagers around your village.]“How could I find these Crows in a modern society? ”An oblivious mosquito with an annoying buzz flies over and lands on Lin Li's hand.“Snap!”[Killed Little Demon Heaven Blood Crow (1/10).]“Eh?!?!”

See you for the first time.
In front of the teaching building, fourteen-year-old Xu Can was sitting in front of the steps crying uncontrollably, when a voice suddenly came from overhead and asked, “What’s the matter with you?”
She was so frightened that she raised her eyes, and was amazed again.
With tears in his eyes, he sniffed and held it for a few seconds, not wanting to tell the truth, “Teacher, I… I didn’t do well in the exam.”
Tong Mingyue sat next to her and chatted with her.
The next day, Tong Mingyue passed by the school’s display board.
I saw that Xu Can, who spent a long time in teaching her classmates who didn’t do well in the exam, ranked first in the overall ranking list, and almost got a perfect score in every subject.
“…”

After working hard all his life, he was still unable to cope with the drag of his background. Before Xu Can was forced to jump off the building, he regretted that he could not see Tong Mingyue again.
When I opened my eyes again, the computer was lit up with a blank document.
Back to sophomore year.
Failed subjects, no money, there are still two professional exams in sight…
In this life, Xu Can walks without heart and heart, with eyes full of eyes, only Tong Mingyue.
