Totem Realm: Am I Chaos at the Beginning?

[Totem Realm He was originally an orphan. He had just received a government subsidy to go to school. By chance, he traveled through time before he could go to school one day. From a two-legged beast to a four-legged beast, there was an additional system inexplicably. After asking, I found out that he had traveled to the world of animated totem fields and transformed into the chaos of the four ancient ferocious beasts. The good news is that there is a system, but what purpose does this system serve besides spoilers? In the world 3,000 years ago, he met his ancestors and the Heart Seizer. Chaos lies above the Totem Beast and the Refinement Beast, but now he is only a larvae, which is still too small. Heart Seizer had helped him, and he should repay this kindness. After 3,000 years, he finally had enough power to rival him, and Besara was about to break through the barrier and come to the human world. As a ferocious beast, what would he choose to do? (A reminder: Private Chaos belongs to the cat family and is a growth type^ω^)
