Carrying Out a World-Ending Mission

The development of civilization into the universe is an unchangeable trend. And this is the story of a group of light guides who lead alien civilizations to save the world! … The information transmitted from light years away is written in this strange light quality and cannot be detected and translated. It is called "light text" by humans. Only after Surutranth invented the orbit did humans look back and discover the Tahur incident. Finally, this type of people are called guides. Because they can pull information from civilizations light years away, they are valued by human beings. Every one of them is precious. "Long time no see, another guide shows up?" "Yes, senior, this trip is based on your approval." "It's been passed down for generations, why bother an old man like me?" "Haha, this is different. Jie Yin No. 7 Guangwen may be the only established one!"
