Light is hypocritical, darkness produces light.
The ancient magic sword has awakened, the war between the worlds of light and magic has reignited, and the forbidden bloodline has stirred up the world.
Mu Feng - the iron-blooded eldest brother guarding the border of the Demon Realm, wearing the Hades Demon Armor, carrying the safety of the Demon clan with his pride;
Mu Xue - the cold and charming empress who dominates the Nine Netherworld, is in charge of all magic, and hides the most paranoid protection under her coldness;
Muchen - the taboo third son of mixed blood of light and dark, holding the fearless magic sword in his hand, struggling to survive on the edge of warmth and darkness;
Mu Yun - the fourth young master of the Sunshine who controls the Black Thunder, is outspoken and outspoken, but is the warmest bond and sharp edge between the brothers and sisters;
Mu Ya - the beloved little girl with twin souls, who heals and kills in one body, is the light that the whole family protects with all their might.
There are no lone heroes, only brothers and sisters working together.
Some people guard the territory, some protect the sect, some bear fate, some venture into the world, and some hide secrets that can subvert the three realms.
When conspiracies arose and powerful enemies surrounded them, the five brothers and sisters stood side by side, using their blood as a contract and in the name of protection, to write their own magical era in the war-torn Demon Realm.
