When Jiang Ming woke up, he possessed the power of immortality.

Facing the cruel and dangerous world of cultivating immortals, Jiang Ming realized his own path of cultivation.

That is, only practicing forbidden techniques!

Blood-burning knife technique, one year of life lost for each cut… Eat me ten times first!

A holy body for a hundred eons, three levels for one day…refined to one hundred thousand levels!

The Heavenly Reaper Technique, if you use it, you will be backlashed by the destiny… Let me first calculate the color of the saint’s clothes tomorrow.

To break the delusion, you need to look directly at the indescribable things…

Birth and death, being scoured by the secluded capital Huangquan every day…

Practicing and practicing… Jiang Ming discovered that his forbidden technique was already invincible in the world!

He was about to join the beta test on the newest VR games, Second World.

The legend of the continent, the battle that brought fame; the Sacred Phoenix Lady, the Windfire Meteor Godrealm saber-art; the pair that ascend and fuse, the golden sun and the blue moon, the fury of the crashing thunder. There is no magic, no battle qi, nor any martial arts in this land. However, there are martial spirits. Ten thousand years have passed since the founding of the Tang Sect on the Douluo continent, and it has declined. A new, proud generation of heaven’s chosen has been born. Can the new generation of Shrek’s Seven Devils rally the Tang Sect and once more compose the song of the Unrivaled Tang Sect?

A million-year-old spirit beast, a sacred deathgod that holds the sun, the moon, and the stars in his hands, and a brand new spirit tool system which caused the fall of the Tang sect. One miracle shall occur after another.

Can the Tang Sect’s hidden weapons rally the winds, and can the glory of the Tang Sect ascend once more? All of this will be continued in the second installment of Douluo Dalu—The Unrivaled Tang Sect!
