Biologist Chen Yuanzhou accidentally traveled to the Qian Dynasty, which was similar to the ancient Qin Dynasty, and became a low-level military doctor in the border town "Cangwu". Here ferocious beasts run rampant, barbarians invade, and people struggle to survive in famine and war.
In an accident, Chen Yuanzhou's blood activated the fragments of the family's "The Classic of Mountains and Seas". He was shocked to find that he could not only summon the strange beasts from the scriptures, but also extract the genes of the strange beasts to strengthen himself and his companions, and even improve crops!
When the plague enveloped the country, barbarian armies were pressing down on the country, and the powerful in the court were quarreling, an unknown little military doctor, starting from feeding the first "eared rat", quietly raised an army of beast souls and embarked on a road to become a god by crushing all enemies.
