Ma Lin knew that although adventure was a lot of fun, people derived even more joy from social interaction.
Adventure areas must have enemies, not just one enemy, but a large group of enemies, and they all had to be intelligent. Only then would the battle be interesting.
Ma Lin remembered a certain competitive game where some people were keen on battling the computer, never growing tired even after thousands of matches.
And various deities could easily create all sorts of monsters.
There was a story that went like this.
There lived a very lonely person in a desolate mountain who was very alone every day. In order to entertain him, the mountain deity commanded a group of rats to fight with him daily. These rats were very clever, and their way of fighting was very peculiar; moreover, if he won, he could loot the rats for his spoils.
The battles were divided into countless levels of difficulty, and the loot was also varied.
