I Can't Save the World

Zhou Qingyuan was diagnosed with an incurable disease, and he knew he didn't have much time left. While passing by a funeral company, he saw an interesting offer. Perhaps because he wanted to get rid of his mediocre life, he customized an interesting funeral service. At his funeral, many knight actors accompanied a female magician actor holding a staff to his tombstone. "The greatest hero in human history, please rest in peace. We will live happily under the protection of your supreme glory." Just when Zhou Qingyuan thought his life was over, he suddenly found himself awakening from a sacrificial altar engraved with magic runes. "The greatest hero in human history, please come back to this world that is about to be swallowed by darkness. Under the protection of your supreme glory, please guide us on the way forward!" This... What happened, you resurrected me? This world has technology and magic? Are there other alien races like orcs, orcs, dwarves and elves in this world? However, I am not the brave man you are looking for, and I will not save the world.
