Beast Taming: Defense Will Eventually Make Me Invincible

[Slow-burn power fantasy + no female lead + data-driven + rich power system + lots of heartwarming everyday moments with cute pets]

Huang Hao spends the entire night extracting mangostin for his advisor, then suddenly dies and transmigrates to Beast-Taming Blue Star. The planet is ravaged by demon empires, and humans form beast-taming bonds with monsters to fight back against the invasion. Huang Hao transmigrates into his first year of high school, just as he is about to become a beast tamer. But with no parents and student loans to pay, Huang Hao can only choose a free monster provided by the state. There are five free types, corresponding to metal, wood, water, fire, and earth, and they can never exceed Level 30. His homeroom teacher urges him to choose a monster of the metal, fire, or earth type, since they hit hard and can become combat-ready quickly. But Huang Hao, after awakening the Trainer System, declares: “Crystal Baby, you're good at defense. You're the one!”
