An ordinary urban office worker accidentally discovered that his old mobile phone had mutated and could receive chat group messages from different worlds. In the group, there are masters of cultivating immortals discussing how to make elixirs, magicians exchanging their experiences on forbidden spells, prosthetics transformers from the cyberpunk world sharing their techniques, and even primitive people from prehistoric civilization asking how to make fire. Zhang Xiaofan initially just wanted to watch the fun, but slowly discovered that by completing the weird tasks issued by the group members (such as helping the cultivator to purchase snacks from the earth, and providing the magician with modern physics knowledge to explain phenomena), he could obtain "red envelope" rewards from other worlds - which may be spiritual energy, magic elements, technology fragments, or even a little divinity.
