Tianlong Yugulu

[This novel is adapted from a true novel. Any similarity is purely coincidental. The Tianlong Escort Bureau is the only "regularly organized" escort bureau in the universe. It has only four members: three unlucky masters and apprentices, plus a young man who was rescued from a mental hospital. They thought they were taking on an ordinary escort mission, but they accidentally tore the seal of the ancient universe. Faced with the powerful evil force, the four masters and apprentices did not back down and started a head-on confrontation with them, but the whole process was full of madness and nonsense.
