Everyone had a kind of mentality of hating the rich. This was called not worrying about poverty, but about inequality. If you had something, he would naturally be angry. No matter where, people would have this kind of mentality, and it was naturally the same here in the myriad realm battlefield.
Although this was the law of the jungle, those who lived in the myriad realm battlefield were, after all, some cultivators, the elites among humans. They were not wild beasts without thoughts. They might respect this law of the jungle, but there was a prerequisite, that was, they did not have the strength to not respect this law. When they had the strength, they naturally had to make their own laws, because people, after all, had thoughts, not just wild beasts that relied on their instincts.
