2533 Underground Ancient City Under normal circumstances, it was difficult for one to die at the Grotto-heaven realm. Given the capabilities of the Martial Dao Prime Body, even if he used all his trump cards and even the Hell Suppression Tripod, he would only be able to defeat a Fiend King at most in melee combat. There was no way he could kill three Fiend Kings in succession. However, the area beneath the Fiend Cave was way too strange. Not only could they not release divine powers or secret skills, even the Grotto-heavens of the Fiend Kings were suppressed and could not be released. As a result, the combat strength of the three Fiend Kings was greatly reduced and they were killed by the Martial Dao Prime Body! The death of the three Fiend Kings caused the entire place to fall into a momentary silence. Even Fiendcelestial Black Heaven and the others did not know if there were any other strange things in the tomb of the Fiend Emperor and did not dare to act rashly. “Let’s capture that sl*t first and not let her escape again!” Ling Xian said in a deep voice. Fiend King Hidden Space and the other five continued to protect Ling Xian as they sped forward. The Martial Dao Prime Body picked up the storage bags of the three Fiend Kings and followed. The expressions of Fiendcelestial Black Heaven and the other Fiend Kings darkened as they exchanged glances without saying anything. However, everyone had already arrived and naturally could not retreat. The dozens of Fiend Kings followed suit. A strange formation was formed in the tomb passage. The seven of them from Firmament Ascension Palace sped at the front while the Martial Dao Prime Body hung at the back alone. Behind him were more than ten Fiend Kings. The three factions coexisted peacefully in this passage! After a while, a faint light appeared in front of them and they had already arrived at the end of the passage. Fiend King Hidden Space and the others escorted Ling Xian out of the passage and everything opened up before them. Ling Xian shuddered at the sight before him! Even Hidden Space and the other three Fiend Kings gasped slightly with shocked expressions and disbelief in their eyes. Up ahead, there was a gigantic ancient city that stood deep underground like a massive object, glaring at the group of cultivators that charged in. The ancient city was majestic and even surpassed the many immortal cities on the ground. If they had not seen it with their own eyes, it would be difficult to imagine that such an ancient city existed deep underground. Everyone realized that there was a high chance that the ancient city was the core of the Fiend Emperor’s tomb! The true treasures, opportunities and inheritances should be in this ancient city! Everyone was invigorated and their gazes burned. Right then, a beautiful figure flashed past the top of the ancient city wall—it was Demoness Ji! “Go!” Ling Xian could not wait any longer and charged towards the ancient city. Fiend King Hidden Hidden Space and the others stood guard at the side while the Martial Dao Prime Body, Fiendcelestial Black Heaven and the other Fiend Kings followed closely behind. In the blink of an eye, everyone arrived at the entrance of the ancient city. The strange thing was that there were two rows of humanoid clay guards standing on both sides of the city gate, wielding clay spears. There were also many clay guards standing on the city wall. They were densely packed and motionless. Some of them wielded bows and arrows and guarded the city wall. Some of them formed groups of 10,000 people that seemed to be patrolling the city walls. They looked orderly and made the place seem heavily guarded. “What the hell is that?” Ling Xian passed by and wanted to step forward and smash a clay figure. However, he was stopped by Fiend King Hidden Space! “Your Highness, don’t act rashly. This ancient city looks a little strange!” Fiend King Hidden Space had a guarded expression as he whispered, “Everyone, be careful!” The Martial Dao Prime Body ignored them and walked past the group from Firmament Ascension Palace and the others before entering the ancient city. When they saw the Martial Dao Prime Body walk over without encountering any danger, Ling Xian’s group and Fiendcelestial Black Heaven and the other Fiend Kings moved one after another and charged into the ancient city. There were all sorts of structures in the ancient city and it looked no different from the immortal cities on the ground. However, the streets of the ancient city were extremely empty and deserted. Apart from teams of clay guards, there was no one else. As the group of them traveled, the ancient city was filled with clay men guarding. There were already hundreds of thousands of them! “As expected of Fiend Emperor Apocalypse.” A Fiend King of Firmament Ascension Palace lamented, “Even if he dies, he has to build such an ancient city in the tomb and create so many clay guards so that he can command thousands of fiend troops after his death.” 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞 Fiend King Hidden Space suddenly frowned, as though he recalled something. Right then, a round of applause sounded from a group of more than 10,000 clay men patrolling at the front. “How smart.” Demoness Ji’s voice sounded among the clay guards with a hint of mockery. “However, do you guys think that these are just clay guards?” Crack! Suddenly, a sound came from the clay guard, as though something had shattered. Creak! Immediately after, the sound intensified and spread through all the clay guards and the entire ancient city! Right in front of everyone, cracks appeared on the mud on the clay guards and they fell off, revealing guards with flesh and blood! Of course, there was no life in the bodies of the guards. However, the weapons in their hands were sharp and cold after the clay was removed. The eyes of the guards were filled with madness as they glared at the people who entered the ancient city with a murderous aura! “Otherworldly soldiers that grew flesh and blood?” Ling Xian frowned slightly. “These are not otherworldly soldiers.” Fiend King Hidden Space said sternly, “Even if otherworldly soldiers manage to condense flesh and blood, it will definitely be incomplete. There’s no way they can be preserved in such a complete manner.” “These people were originally alive back then. They were sealed in the clay by Fiend Emperor Apocalypse with a supreme secret skill for tens of millions of years until they were awakened today!” After tens of millions of years, those guards had naturally died. At that moment, the only thing that drove them was the final consciousness left in their minds by Fiend Emperor Apocalypse! Destruction, conquest and killing! Upon hearing Fiend King Hidden Space’s words, everyone present shuddered and felt chills run down their spines. There were at least millions or even ten million guards in this ancient city. However, back then, Fiend Emperor Apocalypse sealed these tens of millions of fiends and killed them alive as burial objects, burying them underground for tens of millions of years! “It’s no wonder why his title is Apocalypse. To think that he was able to do such a shocking thing!” Ling Xian murmured softly with a hint of envy in his tone. “Kill! Kill! Kill!” Countless awakened guards were controlled by the remnant thoughts in their minds and roared at everyone from Firmament Ascension Palace! Bang! Boom! On the long streets on all sides, ancient chariots sped over with a shocking might! More and more ancient city guards gathered over. It was a black patch with no end in sight. Against such a lineup, everyone present calmed down rapidly. Although there were many guards in the ancient city, most of their cultivation in the past was only at the Earth and Heaven Immortal realm. At best, the strongest was only at the Perfected Fiend realm. Almost everyone present were Fiend King experts. Even if they could not release their Grotto-heavens, they could make use of their physiques, bloodlines and Grotto-heaven Spirit Treasures to kill their way out! “Where’s that sl*t?” Ling Xian surveyed his surroundings, wanting to search for traces of Demoness Ji in the vast army of guards. However, there were too many guards and he could not even see Demoness Ji’s figure. “Your Highness, that woman should be dead.” Fiend King Hidden Space said, “That demoness is only a Grade 5 Heaven Immortal. It’s almost impossible for her to survive the army of guards.”
