When a mysterious phenomenon called "space-time ripples" occurs frequently around the world, no one knows what unknowns are connected behind the unstable space-time structure. Bai Li, a senior high school student, is a young man who is curious about the world but also confused. In an accident, he is involved in a randomly appearing wormhole, and the hand of fate suddenly turns to the lost ancient times.
Coming to a primitive alien world full of prehistoric beasts and full of dangers, there is no system, no plug-ins, only the cruelest law of the jungle. With wisdom, observation and survival instinct, Bai Li began his difficult journey of exploration. He recorded every brush with death, drew an unprecedented [biological illustration], and wrote a unique [survival note].
From the lost tidal flats to going deep into the interior, from encountering conflicts among primitive tribes to exploring the secrets of ancient ruins, Bai Li gradually discovers that the world is not just a projection of the "past". The mysterious [resonance energy], the relics that do not belong to any known civilization, and the increasingly frequent wormhole rifts connecting the multiverse... All point to a truth that is far beyond imagination. When the primitive wildness intersects with unknown whispers, can Bai Li find his way back in this "ark"-like secret realm, or can he uncover the veil of a greater universe?
