As an F-Level Paramecium, I Can Only Learn the Theory of Evolution.

Have you ever heard of the Silurian Hypothesis? In a time wormhole unknown to mankind, the dinosaurs did not become extinct, but were domesticated by ancient Homo sapiens, opening up another civilization trajectory—— Welcome to Planet Terra, a different world two thousand times larger than Earth. This place is full of spiritual energy, and everyone can awaken their martial soul. Beasts can be trained to become monsters, and they can also transform into human forms. Thousands of years ago, the conflict between the human race and the demon race intensified to an irreconcilable level, known in history as the Battle of Zhuolu. The outcome of the war was lost in the annals of history. Only the first generation of the Human Emperor paid the supreme price to exile the demon race to the Starlink Wasteland outside the Great Wall of Sword Qi. Within the Great Wall, the remaining monsters were stripped of their intelligence and kept in captivity in private areas. Some were domesticated and became human companions - passenger pterosaurs soared in the sky, giant dragonflies crossed the oceans, and mosasaurs swam in the deep sea. The other part became wild beasts, wandering in their own land. Until one day, Li Muxuan, a young man who was detected as an F-class useless martial soul Paramecium, relied on the intelligence system to win an opportunity that did not belong to him: a copy of "Origin of Species" from another world... *Silurian Hypothesis: In the Silurian Period (about 440 million to 420 million years ago), there may have been a reptilian civilization with advanced intelligence, which later disappeared due to geological events. This hypothesis is often used to explore the possibility of the existence of "non-human intelligent civilization" and the issue that geological records may not be able to completely preserve the remains of ancient civilizations.
