Undertale: From Underground to the Surface 传说之下：从地底到地面
Most people are already familiar with the full storyline of Undertale, so I won’t go into it here. This book simply goes through the whole story so newcomers can learn the details. You can also choose not to read it; I’m not expecting many readers anyway. Later on, I might write some fanfiction or something, so don’t get your hopes up too high.
