Chapter 571: National Guardian Level Demon King

In the Eastern Continent of Africa, there was the world-famous Rift Valley.

Half a year ago, a lot of wild monsters suddenly appeared here. There were countless of them, and it was impossible to kill them all. To the people of Africa, having more wild monsters was a good thing because that meant they had enough food. Of course, when a good thing exceeded a certain dosage, it would naturally become a bad thing.

In the beginning, all the countries and tribes in the continent were happy about the increase in the number of wild monsters. However, as time passed and the numbers kept increasing, they gradually realized that they were biting off more than they could chew. It was only until several earth-rank Demon Kings led tens of thousands of mystic-rank wild monsters and an endless number of yellow-rank wild monsters to attack the city that they realized that the era of peace had passed!
