Chapter 489: 489 Chapter 489: 100% Poison Immunity Lin Moyu was not surprised that he could level up; he had anticipated it. He leveled up, and his attributes and skills increased. The members of the undead army expanded again, with 33 Lich Generals and a total of 32,670 skeletons. Each type of skeleton reached a total of 10,890. Lin Moyu did not immediately summon the skeletons but instead turned his attention to the entrance of the secret realm. The entrance and exit of the secret realm were shrouded in deadly poison, making it difficult to enter or exit. This poison came from the Poison God, potent enough to kill pseudo-gods and even the avatars of demon kings. Lin Moyu did not know how long it would last; it could be a day, a year, or even ten years. If it were elsewhere, it would be manageable, but in the lower space where the strongest beings were only level 89, it was almost unsolvable. Now that the entrance and exit were sealed and the Dragon Clan was driven away, the next step was to figure out how to get inside. Lin Moyu had an idea before but wasn’t sure if it would work. He could only try. "I killed the Poison God and increased my poison immunity cap, reaching 100% poison immunity." "The spinal fluid of the Poisonous Dragon can increase poison element immunity." "The Poisonous Dragon evolved by consuming the essence blood of the Poison God." "Therefore, the Poisonous Dragon has considerable resistance to the Poison God’s poison." "Let’s give it a try!" Lin Moyu followed his premeditated plan and took out the spinal bone of the Poisonous Dragon. The spinal bone was 100 meters long, with exactly 100 segments, each one meter long. At each connection point, there were three drops of spinal fluid, looking crystal clear like beautiful jade. The entire spinal bone had a total of 300 drops of spinal fluid. Lin Moyu had previously taken three drops, one of which he gave to Han Dong’er to cure her poison. Now, 297 drops remained. Because he didn’t have a suitable container, Lin Moyu hadn’t extracted the spinal fluid. Now, he didn’t need a container; he took it directly. He broke open one segment and swallowed the three drops of spinal fluid. The spinal fluid exploded with a unique fragrance in his body, turning into a warm current that spread to every corner of his body. **[Poison element immunity increased by 1%]** **[Poison element immunity increased by 1%]** Two consecutive notifications appeared, increasing his poison element immunity to 82%. "Three drops increased by 2%, it seems I need to consume more and more, similar to the Electric Element Essence." 𝘧𝓇ℯ𝑒𝓌𝑒𝑏𝓃𝘰𝘷𝘦𝘭.𝒸ℴ𝓂 He broke open another segment and swallowed the three drops of spinal fluid. **[Poison element immunity increased by 1%]** This time, it increased by 1%. He continued breaking open the spinal bone and consuming the spinal fluid. After several attempts, Lin Moyu figured out that each time he needed to consume one more drop than the previous time. In total, he needed 297 drops to increase his poison element immunity from 80% to 100%. Fortunately, he had 297 drops, more than enough, with 89 drops remaining. Lin Moyu ordered the Skeleton Berserkers to keep fighting while he continued consuming the spinal fluid. Eating the same thing repeatedly would eventually become tiresome. Although the spinal fluid tasted good, Lin Moyu started to feel nauseous after consuming so much. He couldn’t help but recall the time he ate desert fruits to practice his skills, feeling a sense of déjà vu. But there was no choice. He glanced at the entrance of the secret realm, still shrouded in poison. He had to finish what he started, no matter how nauseous he felt. Half an hour later, with the final 1% increase, Lin Moyu finally reached 100% poison element immunity. His entire body glowed, and faint green smoke emanated from him. Humans consume various foods, which always leave some toxic residues. Especially for professionals, who come into contact with many toxic substances daily. Although injuries heal, some toxins remain. Over time, these small amounts of toxins accumulate in the body. Now that Lin Moyu had reached 100% poison element immunity, all the accumulated toxins were expelled from his body. Lin Moyu felt much lighter, and although his attributes hadn’t changed, he felt much better than before. Complete immunity to both electric and poison elements was unprecedented in history. If Lin Moyu could see his bones, he would see that they were now as white as jade. His bone marrow was as crystal clear as the spinal fluid of the Poisonous Dragon, making it the best antidote in the world. Lin Moyu immediately put away the Poisonous Dragon’s bones, not wanting to see them again for a while due to the nausea they caused. The entrance and exit of the secret realm were shrouded in poison, making it difficult for anyone to enter or exit. The poison swayed with the wind, expanding but not dissipating, now covering an area of ten kilometers, turning the former battlefield into a forbidden zone. Lin Moyu tried touching the poison with his finger and found no adverse effects. The poison seemed to ignore him. Feeling reassured, Lin Moyu boldly flew towards the secret realm. With 100% poison element immunity, he could move and breathe freely in the poison. Even if he inhaled a large amount of poison, his body would quickly expel it without any residue. Just as he was about to enter the secret realm, a mysterious force pushed him back. The secret realm rejected his entry. Lin Moyu was momentarily stunned before realizing that he was in a very special state. His body was glowing red, indicating he was in the trial period of the **[Primordial Rune]**. During this state, he couldn’t leave the Ancient Battlefield or enter any secret realms or instances. The trial period was fair to anyone who obtained the **[Primordial Rune]**, requiring them to endure for ten days. "I didn’t expect to overlook this detail. With eight days remaining, I’ll have to wait." Waiting outside the secret realm for eight days was a waste of time, but it was unavoidable. Before he could sit down, a cold and powerful aura approached from afar. Lin Moyu looked up and saw a green light in the distance. "Abyssal Fire!" The distant sky turned dark green, filled with the dense Abyssal Fire. A terrifying aura followed. "A Demon King!" Lin Moyu’s expression turned serious. A true Demon King had arrived, not just an avatar but the actual Demon King. The aura was unmistakable, and Lin Moyu couldn’t be wrong. For a Demon King to come to the lower space was quite troublesome. Even with sacrifices of demon flesh and souls, they could only summon an avatar for a short time, no more than a minute. For a Demon King to come in person, they had to enter the deep space first and then travel through the space-time passage to the lower space. This allowed them to stay a bit longer, about an hour if they didn’t engage in combat. If they fought, the time would shorten drastically, possibly to just a few minutes. For a Demon King, even a few minutes were enough to accomplish many things. Lin Moyu sensed the powerful aura, stronger than the Flame Demon King, the Bull King, and even the Demon King avatars he had killed recently. At least a level 92 Demon King, and not an ordinary one, likely an elite. Lin Moyu didn’t panic. He knew the Demon King couldn’t get through the poison. The Poison God’s poison was troublesome even for a Demon King. The Demon King, surrounded by Abyssal Fire, charged forward, burning the poison. The hissing sound of the poison burning was constant, and the Abyssal Fire quickly consumed the poison. Lin Moyu finally saw the Demon King within the Abyssal Fire. Its entire body was shrouded in Abyssal Fire, constantly changing shape within the flames. Lin Moyu recognized it from the information on Abyssal Demon Kings; it was the Fire Spirit Demon King. Its true form was an Abyssal Fire Spirit, an elite Demon King with a level of 91. His judgment was accurate. The Fire Spirit Demon King was indeed blocked by the poison, unable to get through for the moment. But the Abyssal Fire continued to burn the poison, and in half an hour, it would be gone. The Fire Spirit Demon King had no physical form, no eyes, mouth, or nose, making it impossible to read its expression. However, Lin Moyu could feel its aura locked onto him, filled with killing intent. The atmosphere became tense. Apart from the sound of the poison burning, there was no other noise. With the Fire Spirit Demon King locked onto him, Lin Moyu knew that if he left the poison’s range, he would face a terrifying attack. He was unaware that the Abyssal Demon Emperor had issued a kill order for him. Countless Abyssal Demon Kings wanted to kill him. The poison’s range was rapidly shrinking, and during the **[Primordial Rune]** trial period, he couldn’t leave the Ancient Battlefield. The Abyssal Teleportation Stone was unusable, and even Antares’s Dragon Pearl couldn’t help him leave. Moreover, with the red glow on him, even using a random teleportation scroll to escape a hundred kilometers wouldn’t help. The Demon King could catch up in an instant. The **[Primordial Rune]** now seemed like a death sentence. ---
