My summary in case the synopsis does not mention enough to interest you.
This main character (MC) I suspect is from the modern world (never really mention, only my guess) that was reborn into the continent of Stern, the world there is ending as the magic elements in the air is almost gone, and there is only one magician left in the world to fight against the dark forces which is destroying the world.
The MC had been there living for 17 years and is the only magician left, but he is busy at the magic tower "protecting" the library and the people of the town. A fireball from heaven made him awaken in the era of the prosperous magic, 3000 years ago. He became a student at the Magic Academy and he is famed for being the weakest.
So the story will go on to show how he starts to strengthen himself slowly by cultivation and constant training, make potions, go to the training area, go to the beast forest to fight beasts to get resources to train. Along the way he will help his classmates, teachers and other people.
The ladies in this anime are not annoying, unlike many other similar cultivation chinese anime. There is the the teacher that act 任性 (capricious) but I think it's adorable, the class monitor that tries to woo the main lead but is annoyed at his denseness and can be jealous when other girls show their fondness for him, and the noble city mayor's daughter that knows how to 撒娇 and is quite lively.
Main lead can be arrogant but he knows he can handle things. He is quite a cultivation training manic and is quite focus about it, not wanting the female attention.
He is quite rude and arrogant to many old and powerful men like the head of the potion association and the school headmaster as he thinks they are quite dumb to not know the basics and have so many easy questions that they do not know the answers to. He do spend time to enlighten them and the old men are quite eager and humble to accept his vast knowledge.
Is a 爽 anime with no bad scenerio.
A relaxing and cool anime to pass the time. Worth a watch.
