All things in the world come with a price.
The Thousand-Eyed Rat King knew that for Zhang San to grant him such a great benefit, it couldn't possibly come without a cost.
Zhang San smiled slightly at the Thousand-Eyed Rat King and said, "The price is... you must become famous!"
The Thousand-Eyed Rat King's brow furrowed. What kind of price is fame?
Doesn't your human race have a saying about gaining both fame and fortune, or something like that?
Fame, to your human race, isn't it supposed to be a good thing?
Besides, the Thousand-Eyed Rat King himself also very much hoped to make a name for himself along the All Things Path, so all the Demon Clan members would see him with great respect.
The pursuit of his rat life is all about prestige!
So now Zhang San tells him the price is fame?
Zhang San continued to explain with a smile.
