I Changed Classes to Civil Engineering, So How Did I Become the Creator?

Lu Yu transmigrated into a world where games had merged with reality. Everyone thought he was a genius, but under the gaze of the crowd, he awakened the most useless C-rank ability: Civil Engineering!

Nobody believed in his talent. They told him to get lost and haul bricks.

But Lu Yu refused to give up!

He developed his own earthen walls and expanded his system.

Earth Ropes, Lava, Summoning, Arrow Towers, Fortresses!

One week later, the Class Advancement Secret Realm opened!

The prodigies showed off the skill crystals they had earned from killing monsters.

Just as the principal was about to announce the results, Lu Yu raised a hand, and bags upon bags of crystals spilled out!

The principal was left dumbfounded!

The campus belle covered her mouth, unable to believe her eyes!

The visiting officials were so shocked that a teapot toppled to the floor!

Nobody had expected a C-rank talent to take first place!

But that was nowhere near the end

With a thought, a hundred miles around him became a chasm of spikes;

With a point of his finger, towering mountain ranges transformed into an army of giants;

With a lift of his palm, a sky screen formed from the earth blotted out the heavens!

When the mighty alien expert known as the Sky-Covering Flame Phoenix, said to be capable of burning the heavens to ash,

saw mountain giants surging toward it from every direction,

and billions of tons of boulders crashing down in a sky screen overhead, it couldn’t help but curse:

“You call this a C-rank ability!? I can’t believe I ever trusted you humans!”
