(Black technology + science fiction + time travel + auction) Appendix 1: This book is also called "Auction Signing: Mastering Black Technology with the System" Appendix 2: The full name of the so-called "system" is "Combat Irrational Number System" and the "Combat Irrational Number System" is a "spirit body" system. The biggest feature of this "spirit body" is that it can learn and live like a normal person, instead of just issuing a few tasks and giving out a few benefits like a general fixed machine system and just waiting for the results of the tasks. A person named Lu Yanhongtong traveled to a different world in "China" and became a senior high school student who was about to take the college entrance examination. What is different from others is that his identity is not that of a person who died in his previous life and was reincarnated, but that he is a person who traveled to a different world as a devil with superpowers from the era of the devil. As a demon king with superpowers, he obtained a "combat-style irrational number system." Not only that, he participated in an auction and met a girl from the Nebula Civilization, Elena, and later got married to her. Because he is a demon king with superpowers, he is very proficient in skills such as "teleportation", "instant kill", and "one-hit kill". He masters a variety of technologies that are passed down, on the verge of being lost, and lost. In particular, he has designed and manufactured a combat weapon that may be used in future wars - the "Space Carrier." In addition, he also masters super-light speed technology that is currently unreachable by human society and various other types of black technology. Therefore, many professors beg him to share it.
