Is the Student Career Useless? but I Can Learn Anything!

The abyss invades, and humans change jobs to survive. Qi Shuo, who traveled through time, awakened to the "student" profession with no combat power. When everyone thought this profession was too useless, Qi Shuo discovered that he could set skills related to "students". [Study Master]: Ignore the professional barriers, learn all skills in one go, and become proficient in them in a while (As a student, it makes sense to have strong learning ability, right?) [Inferences from one example]: deduce the learned skills into more powerful and more lethal skills (as a student, there is nothing wrong with being better than someone who is good at it, right?) [Time Management]: Control time. Time can be accelerated, prohibited, or regressed as your heart desires. (As a student, you have a heavy workload, so is there anything wrong with being able to plan your time reasonably?) While other professionals were struggling to level up and clear monsters in order to learn a new skill, Qi Shuo directly used the [Xueba] skill on the boss, and learned the boss's world-destroying skill "Sky Fire Meteor" instantly. Then using the skill [drawing inferences from one instance], the Sky Fire Meteor transformed into the World-Destroying Red Lotus, and easily destroyed the boss. When the abyss opened and countless god-level monsters descended, Qi Shuo smiled slightly: "I am a primary school student, please give me some advice from all the monster teachers!"
