Devil's Sky was a Chinese web novel. The realm system was one of the important settings. In Devil Sky Record, every character had a number of realms, and each realm had different abilities and influences. The following is a detailed explanation of the Devil Sky Record's realm system: 1. Basic realm: Including the entry realm, the initial realm, the foundation realm, the entry realm, and so on. The abilities and strength of the characters in these realms were relatively basic, and they could only carry out some simple battles and missions. 2. Ordinary realm: Including intermediate realm, advanced realm, peak realm, etc. The strength of the characters in these realms had been improved to a certain extent, and they could carry out more complicated battles and missions. [3. Realm Breakthrough: A character's strength will increase further on the basis of their normal realm.] A realm breakthrough could include condensing the Sea of Qi, breaking through a bottleneck, breaking through a tight encirclement, and so on. 4. Realm system: In Devil Sky Record, the realm system was a relatively complete system that included different realms, different heavenly tribulations, different bloodlines, and so on. Every realm had different characteristics and abilities. The higher the realm, the stronger the ability. [5. Restraint of realms: In Devil Sky Record, each realm has its own unique restraint.] For example, some realms could cause damage to other realms or be restrained by other realms. 6. Realm Exchange: In Devil Sky Record, characters can increase their strength through Realm Exchange. Realm exchange required a certain amount of Realm Points. After the exchange was successful, the character could obtain a new Realm and increase the corresponding ability. The realm system in Devil Sky Record was an important and interesting setting. It provided many possibilities for the improvement of the character's strength and the development of the story.
