Strength division: divided into before ascension and after ascension.

Before ascension: It is divided into forging the body, practicing qi, building the foundation, Jindan, Yuanying, turning into a god, and crossing the tribulation period. After the Tribulation Period, Ascension is achieved.

After ascension: Ranked in the immortal class, the face can stop. It is divided into four levels: Xia Xian (that is, human immortals), Da Luo Jin Xian, Xuan Xian, and Taihe Immortal (Da Luo Jin Xian and above are all called Shang Xian). And Taihe Immortal is extremely difficult to achieve, so there is a half-step Taihe Immortal and Taihe Immortal. It's just that since ancient times, there are only a handful of people who can truly reach Taihe Immortal.

Immortal cultivators can live to about 120 years old before ascending, and after ascending, the lower immortals can live for about 300 years, the Daluo Golden Immortal can live for 500 years, the Xuan Immortal can live for thousands of years, and the lifespan of the Taihe Immortal can almost reach thousands or even 10,000 years.

Dugu Sword: The sword that all sects in the world want to get, it is rumored that it was built by the old man of Tianshan Mountain Sect thousands of years ago, and then he was scrambled by people in the world, who can get Dugu Sword, who can become the first faction in the world.

Tianshan faction: The largest faction in the world, because the Dugu Sword fell into the hands of Mu Yunfei, the head of the Tianshan faction a hundred years ago, and sat firmly in the world for the first hundred years.

Ancient Beast: Legend has lived for thousands of years, but no one has really seen it, and they don't know what kind of creature it is, only that it is hidden in the Forest of No Return, and no one has ever been able to come out of the forest alive, only the first person in the world, Mu Yunfei, is infinitely close to Taihe Immortal.

Hidden Sword Valley: Legend has it that the Hidden Sword Valley is a place where Dugu swords are forged, but there is no sword there, only a strong sword qi. Legend has it that as long as the lower immortals enter the Hidden Sword Valley, they will be torn apart by the surging sword intent, so no mortal dares to enter, except for some sects, because there are good black iron that can be used to forge swords.

Mu Yunfei: The first person in Taihe Immortal is also the first person in the world, and he became an immortal at the age of 23. The head of the Tianshan faction, armed with the Dugu sword, is unrivaled in the world. It's just that no one knows why such an invincible person would die in the hands of a disciple whose cultivation was only Da Luo Jinxian.

Mu Yunqi: Mu Yunfei's junior brother, but he has always been jealous of his senior brother's talent, and after Mu Yunfei's death, he has coveted the head and the master's mind for a long time, and even chose to cooperate with the demons.

Yu Ziqing: Mu Yunfei's only disciple, and the head of the future Tianshan faction, soared at the age of 21, 2 years earlier than Mu Yunfei, and then became a Da Luo Jinxian in the next 10 years, and has touched the edge of Xuan Xian, and will definitely be able to become a Xuan Immortal within 20 years at the latest, it is such a genius who fell into the devil after a mountain trial, retreated for half a year, and after leaving the customs, he killed his master and seized the Dugu Sword, and defected from the Tianshan faction.

Luo Qingshui: The innkeeper's daughter, originally a mortal, was killed because the innkeeper was implicated by Yu Ziqing, and Yu Ziqing cleared her memory and accepted her as a disciple.

Luo Tianyang: The qualifications are relatively high, but because it is a casual cultivation, he was delayed for time, and he became an immortal at the age of 29. Decades ago, his family encountered robbers on the road and was killed, leaving only Luo Tianyang alone, and Yu Ziqing, who happened to go down the mountain, saw and rescued Luo Tianyang.

Demon Patriarch: Ke Wei, the Demon Patriarch, is ambitious and wants to bring the Demon Clan back to the world.

Mu Yunding: The junior brother of Mu Yunfei and Mu Yunqi, that is, the third junior brother, has a strength of half-step Taihe Immortal, but he left the Tianshan faction, and there are rumors that he is blind.
