Can you sleep peacefully after traveling through time and becoming the son of the world's richest man? Sorry, you traveled to the seventeenth century. Couldn't the seventeenth century just lie flat? Sorry, plague and war can kill you at any time. Can't we find a place where there is no plague or war? Sorry, the richest man in the seventeenth century was in the Ming Dynasty. Since this doesn't work and that doesn't work either, then stand up and fight them.
