The God of Heaven, also known as the God of Nature, has trapped the Heavenly Demon on the Demon Star for almost three billion years. One day after 2300 AD, the demon's magic increased greatly. He broke free from the shackles of the god's magic, escaped from the Demon-Conquering Cave and came to the universe to harm living creatures. The demon wants to obtain the "Cosmic Decryption Book" controlled by the gods to rule the universe and return the universe to its original state. The God of Nature was afraid that the Demon would destroy everything in the universe that he had tried his best to create, so he started a struggle with the Demon. The gods passed on their wisdom and power to aliens and people on earth, allowing them to fight against the evil in the universe. In the end, the gods led the aliens and people on earth to defeat the demons. With the help of the gods, the universe returned to peace and beauty that had never been seen before.
