Apocalyptic Strange Eyes

The male protagonist grew up in an orphanage and never met his parents. He only left one sentence. The dean told the male protagonist, "Your eyes are very important. Protect yourself." On the hero's 18th birthday, the sky turned crimson and the sun gradually disappeared from people's eyes, which was a sign of zombie invasion. After that, the male protagonist began to escape, and gradually became stronger during the escape. He did not join any forces. He only relied on one person, a knife, and a pair of strange eyes to kill countless zombies. The zombie levels ranged from 1 to 15, first-level zombies, and so on. The human level is also a first-level warrior. Not everyone is a warrior. Becoming a warrior is determined at birth. It can be said that it is purely luck. A seventh-level warrior can fly. When the male protagonist was at the seventh level, he received news from his parents, which shocked him. After that, he vowed to become the strongest warrior.
