When the Eagle Hero stole 4000 taels of silver to help someone pay their debts, he used 2000 taels to settle the debt and kept the other 2000 for other use. Guo Fu didn't think much of this, but then she didn't think highly of the Eagle Hero. No-one else found any fault with this though.
From ROCH chapter 33.
The young girl said with a smile, “Well, this is curious; he used
money to buy your life? Eh, how much is it worth?”
That man laughed aloud and said, “My worthless body actually cost more
than beef and pork because the Eagle Hero unexpectedly forked out 2,000
taels of silver for it. More than five years ago, I tried to uphold
justice in Shandong and I killed a crook. Since murder carries the death
penalty, I was sentenced to death so there was nothing for me to say.
Who knew several days later, the Licheng county magistrate interrogated
the local evil tyrant and later brought me forward for a torture session
accusing me of crimes that local tyrant committed, murder, extortion,
rape; all the blame was pushed onto me and the tyrant was acquitted.
Afterwards the Prison
Warden told me that the tyrant bribed the County Magistrate with 1,000
taels of silver, so the County Magistrate transferred all his capital
charges to me. A capital offence is punished with death; ten capital
offences were also punished with death, so I was made a scapegoat. When
I heard such injustice, I shouted loudly in my cell, scolding the
corrupt official, but what use was that?”
“After several days, the corrupt official called for a retrial and that
local tyrant was also kneeling next to me. I shouted, ‘You corrupted
dog, you accepted bribes and distorted justice, you will not have a
peaceful death!’ That corrupt official grinned, ‘Song Wu, you do not
have to speak thus, I investigated closely and found that you were
sentenced unjustly. That crook was not killed by you but by this
tyrant!’ After saying that, he ordered the Yamen attendants to hit him
hard, and used the bamboo torture method (something like squeezing the
fingers between bamboo sticks) on him, forcing him to confess that he
killed that crook and pushed the blame on me. I wasn’t able to figure
this out; that crook was obviously killed by me, how could this charge
be transferred to someone else?”
The young girl heard this and smiled, saying, “This magistrate must be
really blind.”
Song Wu said, “He was definitely not blind; when I got home, my mother
told me after I was sentenced to death, my mother bitterly wept daily on
the street. One day she happened to meet the Eagle Hero passing through
who asked her what was wrong. The Eagle Hero asked around and discovered
the truth; he said he had a matter at hand and didn’t have the time to
find this corrupt official to settle the score, so he gave my mother
2,000 taels of silver to buy my life. After three months, everyone in
the town said the County Magistrate, late one night, was robbed of 4,000
taels of silver and got into a fit of anger. He was so mad he coughed up
blood ever since. I knew this surely must be the Eagle Hero’s doing, so
I didn’t dare continue living there and moved to Jiangnan. After more
than a year, some people told me, a great master with a missing arm was
by the seashore with a big queer bird and he was looking blankly into
the sea, and had been doing so for the past few days. I hastily hurried
up to him and kowtowed to him as an expression of gratitude.”
The young woman suddenly said, “Thank him for what? He paid 2,000 taels
of silver but stole 4,000 taels of silver; so he made a profit of 2,000
taels of silver. How could this Yang scum do business in such an
unscrupulous manner?”
