Lin Moyu wasnât surprised when he leveled up. He had expected it.
With the level-up came improvements to both his attributes and skills.
His undead army expanded once more, now boasting 33 Lich Generals and a total of 32,670 skeletons, with 10,890 of each type.
However, he didnât summon skeletons immediately. Instead, his attention turned to the entrance of the secret realm.
It was sealed by deadly poison, so potent that even fake God-level powerhouses or Demon King avatars couldnât survive it.
This was the Poison Godâs poison.
Lin Moyu had no idea how long the poison would last. A day, a year, or even a decade, there was no way to know.
In other places, it might not matter. But here, in the lower layer where the strongest only reached level 89, it was a critical obstacle.
God-level powerhouses found it challenging to cross over, making this poison virtually insurmountable.
Now that the entrance was sealed and the Dragonkind repelled, his next concern was finding a way inside.
He had a plan. But, there was no guarantee it would work.
Still, there was only one way to find out.
âAfter killing the Poison God, my poison elemental immunityâs upper limit rose to 100%.â
âThe Venomous Flood Dragonâs Spinal Fluid can boost poison elemental immunity.â
âAnd since the Venomous Flood Dragon evolved by consuming the Poison Godâs Blood Essence, it should naturally possess high resistance to the Poison Godâs poison.â
âLetâs put it to the test.â
Following his plan, Lin Moyu retrieved the Venomous Flood Dragonâs Spine.
It was 100 meters long, divided into 100 one-meter segments.
Each segment held three drops of spinal fluid, crystalline and lustrous like fine jade.
In total, the entire spine held 300 drops of spinal fluid.
Previously, Lin Moyu had taken three drops, one of which he gave to Han Dongâer to cure her poisoning.
That left 299 drops remaining.
Since he lacked proper containers, he hadnât extracted the spinal fluid earlier.
But now, he didnât need containers. Heâd consume it directly.
Breaking open one segment, he swallowed the three drops inside.
A delicate fragrance bloomed within him, and a warm current spread through every corner of his body.
[Poison elemental immunity +1%]
[Poison elemental immunity +1%]
His poison elemental immunity climbed to 82%.
âThree drops for 2%... Looks like the returns are diminishing, just like with the Lightning Elemental Essence.â
He cracked open another segment and drank the spinal fluid.
[Poison elemental immunity +1%]
Only 1% this time.
One by one, he broke open more segments, consuming their contents.
Eventually, he figured it out: each time, he needed one more drop than before to gain the same result.
To increase his immunity from 80% to 100%, he would need exactly 210 drops.
With 299 drops, he had more than enough, with 89 to spare.
He ordered the Skeletal Berserk Warriors to keep breaking open the segments, while he focused on consuming the spinal fluid.
But no matter how good something tasted, repetition dulled the flavor.
Though the spinal fluid had a pleasant taste, after consuming so much, Lin Moyu began to feel a bit nauseous.
He couldnât help but recall the days heâd grinded his skills by eating Desert Fruits.
But there was no turning back now. He glanced at the entrance to the secret realm, still shrouded in swirling poison.
He had started this himself; nausea or not, he had to see it through.
Half an hour later, with the final 1% completed, Lin Moyu finally raised his poison elemental immunity to 100%.
A soft glow enveloped his body as wisps of pale green smoke drifted from his skin, dispersing silently into the air.
All living beings accumulate trace amounts of poison over time.
This was especially true for class users like him, who were constantly exposed to various substances, many of them toxic.
Although wounds and illnesses pass, but some lingering traces would always remain, unable to be completely expelled.
Over time, these minute amounts of poison would gradually accumulate within the body.
Now, with 100% poison elemental immunity, every last impurity was expelled.
He felt significantly lighter. Although his attributes hadnât changed, his body felt far better than before.
Complete immunity to both lightning and poison elements, this was unprecedented in history.
If he could have seen his own bones, heâd have found them pristine like jade.
His spinal fluid was now pure and crystalline, as pure as the Venomous Flood Dragonâs Spinal Fluid, making it the finest antidote.
Lin Moyu promptly stowed the Venomous Flood Dragon's Spine. He was done with it. Just the sight made his stomach churn.
The secret realmâs entrance was still wreathed in poison, making passage practically impossible.
The poisonous gas swayed with the wind, expanding rather than dispersing, now blanketing a full 10 kilometers, turning the battlefield into a forbidden zone.
Lin Moyu extended a finger into the poison cloudâno reaction.
The poison ignored him completely.
Only then did he relax and begin flying toward the secret realmâs entrance.
With 100% poison elemental immunity, he moved and breathed freely in the poison cloud.
Even though he inhaled vast amounts of the poison, his body expelled it instantly, leaving no trace behind.
But just as he was about to enter, an invisible force flung him back.
The secret realm had rejected him.
Lin Moyu paused, then realized that he was currently in a special state.
A red beam of light shot skyward from his body. He was undergoing a Primordial Rune trial.
In this state, he couldnât leave the Immemorial Battlefield, nor enter any secret realms or dungeons.
The trial lasted a full ten days for anyone who obtained a Primordial Rune. No exceptions.
âI canât believe I missed that. Eight more days⊠Iâll just have to wait.â
Wasting eight days outside the secret realm was frustrating, but unavoidable.
Just as he was about to sit, a cold, powerful aura surged in the distance.
He looked up.
In the distance, a green glow lit the sky.
âAbyssal Fire!â
The horizon burned with deep, inky green flames.
Then, an overwhelming aura surged toward him.
âDemon King!â Lin Moyuâs expression darkened.
This wasnât a God-level avatar, but the main body of a Demon King.
The difference in aura was undeniable. Lin Moyu could tell instantly.
For a Demon King to descend into the lower layer was no small feat.
Normally, even with a sacrificial rite involving Demon flesh and soul, only an avatar could be summoned, one that could remain less than a minute.
But for the true body to arrive, the Demon King had to first go to the deep layer, then traverse a spatial channel.
This allowed them to stay longer. Without engaging in battle, they could remain for up to an hour. But if they fought at full power, that time would shrink to mere minutes.
For a Demon King, let alone an hour, even a couple of minutes was more than enough to accomplish many things.
Lin Moyu could feel the crushing strength of the aura.
This Demon King was stronger than the Fire Demon King, the Tetrawing Bull King, and even the Demon King avatar heâd slain days ago.
This one had to be at least level 92 Demon King, and not just an ordinary one, but likely an elite rank one.
He didnât move.
Cloaked in poison gas, he knew the Demon King couldnât charge in carelessly.
Even Demon Kings would dread the Poison Godâs poison.
The Demon King approached, engulfed in Abyssal Fire. The Abyssal Fire clashed violently with the poison gas, producing constant sizzling as it burned through the haze.
Through the flames, Lin Moyu finally saw the Demon King clearly.
His entire body was wreathed in Abyssal Fire, his form shifting and twisting without a fixed shape, constantly changing within the inferno.
Lin Moyu recognized him instantly from recordsâthe Fire Sprite Demon King, a Demon King said to be born of Abyssal Fire, of elite rank and level 91.
Lin Moyuâs judgment was far off.
The Fire Sprite Demon King was indeed halted by the poison gas, unable to break through for the time being.
However, the Abyssal Fire continued to devour the poison gas; at most, it would take half an hour for the poison to be completely consumed.
The Fire Demon King had no physical formâno eyes, mouth, or noseâmaking it impossible to read any expression.
Yet Lin Moyu could feel his aura locked onto him, radiating murderous intent.
A heavy silence descended.
Aside from the crackling sound of poison being burned away, not a single noise disturbed the air.
Under the Fire Sprite Demon Kingâs lock-on, Lin Moyu faced a terrifying attack the moment he stepped outside the poison gasâs range.
Lin Moyu was unaware that the Abyssal Demon Emperor had issued a kill order against him, that he was the target of numerous Abyssal Demon Kings.
The range of the poison gas was rapidly shrinking. Due to the trial period of the Primordial Rune, he could not leave the Immemorial Battlefield for the time being.
Neither the Abyssal Teleportation Stone nor Antares's Dragon Bead could help him escape.
To make matters worse, his body glowed red, making him an easy target even if he used a Random Teleportation Scroll to flee 100 kilometers. The Demon King would catch up instantly.
At this point, the Primordial Rune felt more like a death sentence than a blessing.
