Warhammer 40,000, Transmigrated and Became the Greenskin Great Techies

[This is a lighthearted, humorous, non-violent, non-female-lead, system-based, and villainous story. Read with confidence!]

On Earth, Li Hua, an ordinary college student who loves the Warhammer universe, is unexpectedly transported to the Warhammer 40K universe by sheer luck (on a physical level), born as an ordinary green-skinned orc boy. To survive, with the help of a system and his knowledge of the Warhammer universe, Li Hua gradually grows into a powerful green-skinned mastermind who unifies the planet. He is later recruited by Mag Uruk Sarak, the Bonecrusher, thus beginning a massive, galactic-shattering conflict!
