On page 51 the author/artist made a mistake, it should have been 1 golden log, or 10,000 gold coins, not 10,000 golden logs.
A single golden log is 1 billion yen. 10,000 golden logs would be 10 trillion yen
@daisora There are 200+ translated chapters out there, but the TL quality is shit. TOOR Scans TL quality is much better. @RonBWL and his team are doing an amazing job, so the 200+ MTL chapters are completely irrelevant.
