My Grandfather Zhu Yuanzhang

[After crying at the grave, Zhu Yuanzhang begged me to inherit the Ming Dynasty]
High school senior Zhu Xiongying has a secret. He lived in ancient times when he was a child!
Originally, he would carry this secret with him throughout his ordinary life, until he cried to the grave of his guardian grandfather before going to college, and an excited voice came from the grave.
"——Dasun, are you alive?"
Zhu Xiongying: "You said you are my grandfather? I still want money from Qin Shihuang!"
Zhu Yuanzhang: "You want money? Burn the treasure banknotes! Give me as much as you want!"
When Zhu Xiongying watched the treasure banknotes being acquired by antique dealers, he finally realized that the time and space wormhole on the tomb can distort the time properties of objects!
Does that mean...
"Boss, bring me a box of 98-year-old 98k! Don't fool me if I'm not old enough!"
"Do you still have the replica steam engine from the Museum of Old Objects? Bring two! "
As advanced "underground technological products" and mysterious "future secret information" were traded through the space-time wormhole, Zhu Yuanzhang fell into deep thought a few years later, looking at the Ming Dynasty that had undergone earth-shaking changes.
"Grandson, when will you inherit our kingdom?"
