This is actually a good premise, but the execution is just horrible. Either the translator skipped paragraphs, or the author doesn't feel the need to explain or plan anything properly.
Examples:
-MC transfers 1-3 days of cultivation every day, despite receiving multiple days of cultivation each time. We could say he cannot transfer the cultivation given by the system, but that means he can only transfer 1 day since technically he gave away the previous day's cultivation.
- Pick a hard technique because the longer it takes to cultivate the better. Huh? Why?
- Since he only gives the pet 1-3 days of cultivation at a time, it should be impossible for his pet to keep up with him, since he gets much more in return. Yet, their levels are synced.
- MC reaches bottleneck and needs combat to breakthrough. How much combat? 1 fight...
All interactions in the school are just 1 badly done cliché after another. So monotonous and uninspiring that you might as well just skip it.
I wish another author copied this theme and did a good job with it.
