Tales of the Behemoths of Mountains and Seas

This is a war novel about giant beasts fighting in massive armies in the world of Shan Hai. There's nothing perverse about it, no female lead, no golden finger, no System, no cheats, no plot armor, and no luck. The protagonist survives through caution alone. The world is exceptionally dangerous. By the time you realize you're in danger, it's already too late.
