I'm in the Symbiotic Era

"I Am: Era of Symbiosis" In the apocalyptic wasteland, zombies are rampant, and endless monsters emerge from the rifts in space. He is a boy abandoned by the world - his superpower is a "symbiosis contract", but he can't find any creature willing to live and die with a waste. It is a dying vine, struggling to survive in the cracks of the ruins. Its leaves have dried up, its roots have rotted, and it has only its last breath left. That day, he stretched out his hand: "Are you willing to live with me?" It used its last strength to wrap around his fingers. —— This is not a story about "powers to defeat monsters and upgrades in the end of the world". This is a story about two weakest lives proving each other's existence in despair. He became less and less human - his blood turned green, his heartbeat slowed down, and his pupils grew plant patterns. She became more and more like a human being - learning to protect, learn to be angry, and learn to gently cover his eyes with leaves. She was speechless, but the trembling of every leaf said the same sentence: "I'm here." —— Double helix narrative: odd-numbered chapters are his struggles, and even-numbered chapters are her perceptions. The two lines are intertwined, and you won't understand until the last page—— From beginning to end of the book, she answers his fears. Cruel apocalypse, ultimate tenderness. —— "I'm here." Two words, running through three hundred years. From the first speaking, to burning up, to rebirth, to eternity. Turn the first page and you'll hear that voice.
