Zone Zero: Inexplicably Fused with Sans After Time Travel

[Time Travel + No Heroine + Second Creation Fanfic + UTAU + Zero Zone World View] "You mean, I went out to buy groceries and then traveled to New Ailidu?" Shan Yue looked at the scene in front of her and was very confused. Coffee shops, ramen shops, toy stores... Plus the video store all told him this cruel reality. And he seems to be fused with... Sans' soul? In short, at least he has some ability to protect himself. But in this cruel post-disaster world, Shan Yue's combat power is just that of a soldier. Want to become stronger? Go kill monsters and upgrade! But this time travel also allowed him to make many friends, Zhehe Ling, Chou Tuwu... This also caused some disturbances in Shanyue's ordinary life. In short, what will happen in the next days depends on Shangyue's own efforts!
