"I let them all out." The earth spirit beast said disdainfully: "With the strength of your companions, you also want to enter the main hall to seize Yan Chengfeng's three treasures, it is simply looking for death." Let me tell you, the guardian puppets on the periphery of this mausoleum are all rubbish, and the really powerful guards are in the nave and the main hall. Who is Yan Chengfeng? Do you think he will use some garbage to guard his mausoleum? Not to mention your companions, even if you can exert the same strength as before, you will not be able to break through the nave. ”

Hearing that the dragon head had gone out safely, Leng Xuan suddenly breathed a sigh of relief, and then asked curiously, "What is so powerful about the middle hall and the main hall?" The earth spirit beast smiled and said, "Boy, have you ever heard of the thirty-six Tiangang and the seventy-two earth demons? Leng Xuan shook his head, indicating that he didn't know. Seeing this, the earth spirit beast couldn't help but sneer: "Even they don't know, and they dare to break into the mausoleum, you kid is really bold." After a pause, he continued: "Anyway, it's okay to be idle, I'll tell you about it." These thirty-six Tiangang and seventy-two earth demons were private soldiers personally cultivated by Yan Chengfeng back then, and the strength of each of these people had reached the Yuan Infant Stage or the Out-of-Body Period. Of course, their single strength was not very powerful at that time, and in the cultivation realm back then, there were strong people everywhere, and cultivators in the Spiritual Silence Period couldn't get on the stage. However, the power of the Thirty-six Heavenly Gang and the Seventy-two Earth Demons was not their personal strength, but the formations they used, the Tiangang Array and the Earth Demon Array. These two formations are ancient strange formations, and their power is very terrifying, once they are formed, even if they deal with the cultivation powerhouses in the merger period, they can be killed. ”

"Not only that, Yan Chengfeng, with his extraordinary talent, actually researched a method to combine the Tiangang Array with the Earth Demon Array to form a Tiangang Earth Demon Array. After the completion of this large array back then, it could be said to be invincible, and few people in the cultivation realm could crack it. In the later battle between good and evil, the ten top powerhouses of the righteous path joined forces to break this array and destroy the Holy Heavenly Gate. And the thirty-six Tiangang and the seventy-two earth demons also suffered heavy casualties as a result, and less than half survived. At that time, Yan Chengfeng saw that the defeat was decided, so he fled with the remaining subordinates. Later, Yan Chengfeng saw that his limit had arrived, and while building the mausoleum, he arrested cultivators everywhere and reorganized the new Thirty-six Tiangang and Seventy-two Earth Demons. Hearing this, Leng Xuan couldn't help but wonder: "Could it be that those captured cultivators are willing to become Yan Chengfeng's subordinates?" ”

The earth spirit beast laughed and said, "What if you are unwilling? Yan Chengfeng didn't need them to be loyal to him, because what he wanted to do was to establish a Thirty-Six Heavenly Gang Seventy-Two Earth Demons of Death, so for him, it didn't matter if those cultivators resisted. Yan Chengfeng used a secret method to make the one hundred and eight people lose their vitality, and then supplemented it with various medicinal materials to refine a group of living dead subordinates. It's a pity that although those people have been refined into the living dead, the powerful strength in front of them has not been retained, and they have all regressed a lot. Moreover, because the cultivators that Yan Chengfeng captured later were all of different strengths, their strength was different. ”

Leng Xuan said curiously: "Then what level of strength do they have now?" ”
