"Young girl from Mondstadt delivers drawing of the Swordfish II captain and me. +50 energy"
That's not +50, that's at least +900 right there. On the left side there are four +100s, and on the right there are three. We can also see two more numbers on the right side that are partially obscured (a zero and what is presumably the upper right corner of another zero at the top, and a 1 and a 0 at the bottom), but we can safely assume these are also meant to be +100s, so we arrive at +900 minimum.
