   These 4 books are all about the development of technology, mechas, and battleships. Do you also yearn for the mystery of the universe? "The warship now activates the curvature drive mode, has locked the opponent's warship, and applies to fire - allowed to fire" The first book is about building Noah's Ark in the end of the world (the system automatically builds it) and upgrading it to a space battleship step by step. At the end of the day, the aliens come, and let's see how the protagonist can defeat all the magic with the mecha. The second book is Cosmic Federation. The background is that human beings have developed beyond the solar system and formed an alliance. The protagonist is a mecha and a mechanic who can become a genetic warrior and drive a mecha to resist foreign invasion. The third step is also to develop the solar system, and the final step is to step across the Milky Way, form an alliance with alien forces, and jointly defend against the enemy. The fourth one is systematic. Through mining and upgrading, you can then occupy alien planets and develop your own power.
