Invincible Salted Fish System

If I don't practice, I won't go around looking for treasures to upgrade. You only live a hundred years, so why not just be a salted fish in peace. After sunbathing side A, sunbathe side B, drinking tea and petting the cat. Wouldn't it be nice to just show off when you have nothing to do? However, the people in this world are too weak. They practiced hard for a year and couldn't make a breakthrough, but I made a breakthrough as soon as I woke up. The elixir they concocted is regarded as a treasure, and the snacks for my pets are a hundred times stronger than it. When I practice martial arts, I can reach the peak level in just one glance, but they have been practicing for decades and still can't touch the threshold of the peak level. So, just let me be a salted fish in peace, and don't keep coming to attack me!
