Fairyland Invasion, but I Have Just Returned to Reality

[Invincible flow + return of the boss + decisive killing + multiple female protagonists + heart-throb male protagonist + micro group portrait] What should we do if we travel into a world of immortality where human life is at stake, the weak eat the strong, and gods fight? Gu Nanxuan's answer is: He wants to destroy the sky! Over four hundred years of ups and downs in the Immortal Realm, Gu Nanxuan, the former genius student of Blue Star, traveled back and forth to the "Immortal Realm". From being an abandoned son in the Western Desert with nothing, he broke through the shackles of the Heavenly Tribulation, cultivated the Fate-Knowing Sword Cultivator, and stood above the endless creatures. Slash the sky and shatter the sun, turn the world upside down, destroy the world, and possess the power to penetrate the heaven and the earth! ! ! Even though he was entangled by the Immortal Family, he still smashed the boundary wall of the Immortal Realm with one sword, escaped into the air, and finally returned to Blue Star. But soon after returning to Blue Star, crises came one after another! Gu Nanxuan: "It seems that "Immortal Realm" should let me go without interrupting! " Spiritual energy begins to revive, extraordinary things appear in the world, catastrophes come to the world, and the whole world is shrouded in the shadow of the coming of "Fairy Realm". All living beings prostrate themselves, waiting for destruction. But they forgot that a powerful man who fought out of the endless fairyland and smashed the barriers of the fairy world returned to this land. "It doesn't matter, I will take action!" Gu Nanxuan smiled proudly, "This one, the Military Training Bureau!!!" As a result, the ending began to turn upside down, and the stars that had been dormant for a long time in the Blue Star were shining dimly one by one. This time, it is "Blue Star" that comes to "Fairy Realm"! ! !
