Lin Mo is an ordinary office worker, living an ordinary life from nine to nine every day, until he picked up a strange "puppy" on the roadside. This "puppy" eats an astonishing amount. One meal can eat up a week's worth of food. It also spits out a cloud of black smoke from time to time and has two small horns coming out of its head. Just when Lin Mo was wondering if he had picked up a monster, a message suddenly popped up on his phone:
[Congratulations on binding the "Mountain and Sea Shuttle System"! It has been detected that you have conquered the mythical beast "Taotie Cub", the system is being activated...]
From then on, Lin Mo's life changed completely. He was forced to shuttle between the real world and the mythical world of "The Book of Mountains and Seas" to complete various tasks issued by the system: looking for missing mythical beasts, repairing broken mountain and sea maps, and preventing mythical creatures from invading the real world... And that gluttonous "puppy" turned out to be the cub of the ancient ferocious beast Taotie. He was both his cute pet and his strongest fighting partner.
In mission after mission, Lin Mo gradually uncovered the secrets of the world of mountains and seas, met mythical beast companions such as the Nine-tailed Fox and Qilin, and encountered dangerous enemies such as Qiongqi and Yaozhu. He grew from an ordinary person to the guardian of the world of mountains and seas, shouldering the heavy responsibility of maintaining the balance between the two worlds.
However, as the mission deepened, Lin Mo discovered that the crises in the real world were far more complicated than imagined, and his life experience was inextricably linked to the world of mountains and seas...
