Infinite Blue Bars, but Only Draws A

After working overtime all night, I was summoned by another world as a savior. They say that I am the chosen one who comes once in a million years and holds the hope of the entire world. They presented the "holy fruit" that is said to be able to reach heaven in one step. I took a closer look—— Isn't this the common... Sweet potato in my hometown? ! Wait, could it be that the roasted sweet potatoes, dried sweet potatoes, and shredded sweet potatoes that I have eaten for more than 20 years have become my capital to crush the other world? Facing the arrogant elves, bloodthirsty demons, and insidious "gods", I, Lin Ke, an ordinary urban social beast, a "super soldier" with infinite magic power but only basic magic, decided to use my own way to "teach a lesson" to this magical world. From a low-level soldier to the king of all demons, from being betrayed to leading the alliance... Don't ask me why I'm so strong, just ask-- Sweet potatoes, enough!
