Hello Demon Lord

The world is about to be destroyed by skyfire. The time traveler is shocked to find that there seems to be something wrong with his system. There is no girl, no redemption, no space, no time travel, no reward, that's all. Why is there still an obliteration mission? Yes, if there is no fantasy cultivation in this world, I will pursue science and technology. If there is no space teleportation, I will build spaceships. If you don't believe it, I can't run away! My journey is to the stars and the sea! PS: The prequel is a comparative ink, which can be skipped and will not affect subsequent reading.
