Zhu Yuanzhang: Is This Idiot My Lost Son?

We are Zhu Yuanzhang.
Our long-lost son has been found, but he seems a bit...stupid...
When he called me dad, he had a silly smile on his face, but he could lift an eight hundred catty copper tripod with one hand.
He didn't know a few Chinese characters, but the drawings he presented allowed Ming Dynasty to build a steam engine two hundred years ahead of schedule.
He spoke straightforwardly, but made all the civil servants speechless.
It wasn't until the night of the White Lotus Sect's assassination that this idiot stood in front of us, his hammers stained with blood and shouted: "Dad, hide, let me beat them to death."
Only then did we realize that this is not a stupid son... This is the strongest patron saint given by God to the Ming Dynasty.
