Traveling Through Prehistoric Times and Playing with Black Technology

I recommend it. There are so many monsters in the prehistoric world. The skin and horn scales on their bodies are good materials for weapon training. They are so big. There must be a lot of mineral veins, and the spiritual energy nourishes those mineral veins. They are also good materials for weapon training. Since it is technology, I think we can learn from the technology in the super seminary to build some large-scale astronomical computers or something. I feel there is something wrong. It is a magic weapon. It is too easy to copy. There are rules on the magic weapon. Some are born and raised by nature, and some are refined by people and add rules to form magic weapons. At the very least, you need to understand the rules above to copy them. The author feels that if it is inappropriate, then you should not pay too much attention to the latter point.
