I Am the Mecha Creator

After transmigrating to Earth a thousand years in the future, where spiritual qi revival has begun, he unexpectedly awakens the Mecha Creation System.

He adds one Ancient Maja Sacred Method Hard Armor, one-star blue; twenty Cleansed Beast Furs, one-star green; and a first-grade Transcendent Demon Blood to the forge, and ends up with a two-star purple piece of equipment.

He puts two ordinary ninth-grade Evil Spirits and three superior ninth-grade Converging Spring Cat Demons into the cultivation vat, and they fuse into an epic fifth-grade Demon Spirit.

An epic fifth-grade Demon Spirit + two-star purple gear + an Energy Core holding 27,000 units of energy = Mecha Devouring God Tiger.

Years later, the protagonist looks out over the mecha city under his command and smiles with satisfaction.

Multiple heroines, but no, he won't grovel for them.
