I'm Doing Construction Work with Goblins in Another World

When others traveled through time, Long Aotian started, with the artifact close to him. I traveled through time and started as a goblin with zero combat power. Other people's systems are murderous and explosive, and their skills are unparalleled. My system is keen on infrastructure construction, and the first order of business was... Asking me to build a public toilet? When the professional knowledge of civil engineering meets a group of green-skinned enemies with no brains... Lin Qi realized: It turns out that if you want to survive in the abyss, you must be a professional counterpart! This is a hilarious story about an unlucky civil servant who leads a group of goblins and uses digging holes and inventions to "create a city and defend" in another world, while also dominating the abyss.
