Even If It's a Fisherman's Profession, so What?

This is a world built based on basic principles. Therefore, this world is not fantasy, but physical and rigorous, although it is packaged as a gamified world on the outside. Here, immortality, magic, and skills are unified. Spiritual power, magic power, and mana have the same origin. Only by understanding the world can you become a strong person in the world, even if the level is very low, even if the skills are very useless. P8 programmer Yang Guang came to this world by chance. Because he wanted to raise fish in peace and quiet, he chose a low-skilled professional fisherman. He thought this was a world of farming and cultivation, but in fact it is a world full of dangers and challenges. There are no cheats and no plug-ins. Let's see how the programmer uses his professional skills and the experience accumulated from countless failures to become a legend (to prevent spoilers).
