The Only Immortal in the Nine Realms

In ancient times, there were nine realms: immortals, demons, Buddhas, monsters, underworld, humans, mountains and seas, star abyss, and Guixu. Each of them guarded its own territory and never violated each other for ten thousand years. However, a "Heavenly Ranking" suddenly appeared in the immortal world, and the book said: "When the nine realms are united, a single immortal can survive; all the spirits fight to cross, and the road is forged with blood." As a result, the beacon fire burned throughout the eight wastelands, and all living beings were like ants. On the border of Daxia Kingdom, there was a blind young man named Azhi who made a living by copying tablets for others. He didn't know that the "fate-defying mark" on his wrist that was covered by copper coins was the missing word on the first line of the Immortal List. He begged to live, but he was pushed to the top by fate; he begged to die, but he was praised to the top by all living beings. When Ah Zhi trampled the nine realms with his mortal body, he saw the person holding the pen—— It turns out that the so-called "lone immortal" is just an abandoned child from a higher place. What he wants to do is not to climb to the top, but to overturn the entire mountain.
