This World Is Not Very Scientific

In this war world, there is science; there is magic; there are gods; there are monsters and beasts; there are air soldiers; and there is energy. Xu Ran was originally one of the few disciples of the Kongtong Sect, but he was suddenly reborn into this world. During this period, he discovered that he had the ability to absorb source energy to improve himself... His original purpose was just to protect himself and his sister, and to survive smoothly in this war world, but he slowly discovered that this world did not seem to be very scientific. Many years later, Xu Ran looked back on the past and realized that he had killed gods, raised red flags, and slain monsters, becoming the number one air soldier in the kingdom... Looking down at the war, the red flag shines on the world, and indifference will eventually leave.
