The world is divided into three realms: clouds above, humans in the middle, and demons below.
The human world is rich in resources, but the land in the demon world is barren, and the demons are cunning by nature and like to plunder. Therefore, monsters often wreak havoc in the human world and destroy all life. Because the Elf King of the Cloud Realm has powerful Spirit King power, the Demon Realm does not dare to act rashly against the Cloud Realm.
Cries, calls for help, and screams occurred one after another in the human world. The late Emperor of the Yun Realm couldn't bear it and reached a consensus with the Human Emperor: the Human Realm would pay fruits and vegetables to the Yun Realm every year, and the Yun Realm would send troops to garrison the Human Realm to ensure peace in the Human Realm.
After being protected by the Cloud Realm, the monsters had to withdraw from the Human Realm. However, the Human Realm is vast and there are still places where they are attacked...
Purpose: When you meet someone who is loyal to you, you should cherish it.
