Chen San Ye spent money to buy fierce beasts from the protagonist, and the protagonist helped hunt them. Originally, giving the tiger away was no big deal, but Chen San Ye practically used coercion and enticement. Wouldn't it be absurd for the protagonist to give it to him again? And don't forget, the protagonist has a system. What kind of person is Chen San Ye? Doesn't he have a clue? Since the tiger had a better destination, why give it to Chen San Ye?
As for Chen San Ye, the fact that he could send his son to Green Mountain City and even have a chance to enter the Blood Refining Realm in Fierce Mountain Hall was almost entirely due to his monopoly on trade between Small River Village and the outside world. He was never a good person to begin with. The money was given to the protagonist, but whether the protagonist could actually spend that money was questionable.
Or perhaps, he never intended to give the money to the protagonist at all, but merely used it to entice the villagers. When he found that enticing the villagers was useless and everyone who went into the mountains died, he could only increase the enticement to make the protagonist go. But even if the protagonist hunted the fierce tiger and he gave a hundred taels, that hundred taels, along with the previous amount, would definitely be taken back.
It's just that the protagonist didn't want to bother with these matters. He was leaving soon and just wanted to raise enough money or resources as quickly as possible to leave Small River Village and enter Green Mountain City.
What did Chen San Ye's rotten affairs have to do with him? Unless the other party provoked him.
