Lucas Aurelius, a mechanical repairman who has lived for thousands of years (currently known as a mechanical repairman), spends his daily life repairing boilers, criticizing the church, and feeding moldy Roman military rations to the unlucky (whose alchemy is wrong?) God Ed trapped in a steam engine (which is okay in a sense).
Until one day, he was tied to the altar by cultists——
"Your altar is the steam bathtub that I repaired, and the sacred object is Caesar's sandals?" Lucas sneered with a wrench in his mouth, "Ed, come out and explain!"
The god's weak but stubborn response came from the boiler: "... I only made a bet with you when I had gear oil in my brain!" (It seems that it is very accustomed to living in the boiler)
