Zombies, Serpents, and Tyrants

[No System] [No superpowers] [No harem] [Plot-driven] [Road-trip story] [Decisive and ruthless] [Reborn in a parallel world.] [A young experimental subject sets out to find his family.] [Synopsis 1]: An aberrant giant snake is right on my heels. A mutated tyrant weeps and wails. The Snake of Truth follows me. The mighty tyrant sobs as he speaks. The blind become monsters with a hundred eyes. The lame become centipedes with a thousand legs. The deaf gain ears that catch every sound. The mute sing with heavenly voices. Zombies are great, zombies are fine, mutated zombies squeal and whine. Everyone says tyrants are great, but no one sees their obsessions laid bare. [Synopsis 2] Shiyi is reborn in a parallel world overrun by zombies. To find his one and only family member, Shiyi embarks on what is supposedly a journey to find his younger sister. Along the way, he will encounter many tyrants, setting one adventure after another in motion. [Tyrants: Zombies mutated by powerful obsessions. They are usually more intelligent than ordinary zombies.] [PS: This is not a power-leveling cultivation novel, so the power scaling won't get out of hand. Tyrants are not invincible; they are all flesh and blood.]
