Proud Sky King was one of the Ten Great Kings of the Heaven Region.
His cultivation was extremely profound, and his abilities were extremely powerful. Although he was also at the peak of the Semi-Divinity realm, he was invincible among his peers. Other than a few Kings, he was simply invincible.
Every king was an overlord of a region. Every king was a supreme existence.
This was because they were known as the Kings of the Immortal Realm and the Saint Realm. They were the top ten experts recognized by the Immortal Realm and the Saint Realm. They were the strongest experts at the peak of the Semi-Divinity realm.
These people all controlled a Heaven City and were the rulers of a Heaven City.
More importantly, these kings were protected by the immortal realms and the saint realm. No matter how powerful the experts in the Heaven Region were, they wouldn't dare to provoke these kings because they were protected by the immortal realms and the saint realm.
