The Old Gods Installed an Engine for Me?

When Chen Mo woke up, he found himself lying in a mass grave in the huge abyss city. To make matters worse, his heart was ripped out. The most bizarre thing is that the original heart is gone and an "engine" with unknown energy has grown? In this desperate world full of aberrant monsters, steam machinery and evil god worship, others gain strength through prayer, and he becomes stronger through devouring. Others are worried about losing control and turning into monsters, but his engine has a built-in anti-addiction system - it is not only immune to contamination, but can also accurately see through the weaknesses of all attacks. Will the Extradition of the Sacred Heart take away his original heart? Then he would crush the heart of the entire church. Do the upper class nobles regard him as an ant? He stepped on their heads and climbed to the peak of Ewelon's power step by step.
