**Chapter 1319: Communicating with Stone Demons is Really Exhausting**
The sword light exploded, and the two Stone Demons rolling forward were shattered, their bodies turning into large chunks of stone, scattering everywhere.
The bodies of Stone Demons are composed of stones, and the higher their level, the thicker and heavier the stones.
The stones serve as both their bodies and armor, making Stone Demons' defense the best among the demon race.
The Skeleton King's sword injured the two Stone Demons but couldn't kill them instantly.
Both Stone Demons were at the seventh level of the Divine King realm, not much weaker than the Skeleton King.
The shattered stones rolled back, and the laws acted as threads, pulling the stones back together to reassemble their bodies. However, there were now gaps in their bodies.
The Divine Slash wasn't without effect.
The two Stone Demons stared at Lin Moryu with full vigilance, their eyes filled with shock.
They were surprised to encounter a human here.
As far as they knew, humans hadn't set foot here for over a thousand years, so why were they here now?
What puzzled them even more was that the human in front of them was just a True God.
Stone Demons, following their habit of not thinking about things they couldn't understand, began to show fierce glints in their eyes, hidden behind the large stones.
"Human brat, die!"
Without any unnecessary words, the Stone Demons attacked directly.
A piece of shattered stone appeared beside Lin Moryu, with liquid faintly flowing within it, a piece of the Stone Demon's flesh.
In the outer layer, there were a total of four Stone Demons at the seventh level of the Divine King realm.
After Lin Moryu killed one, he used it extravagantly as a resurrected being but didn't get much useful information.
The remaining three were used as materials for corpse explosions, becoming powerful weapons in Lin Moryu's hands.
With a flash of light in his hand, Lin Moryu locked onto the souls, and the Stone Demon's shattered stones broke apart on the spot.
**Stellar-level Spell: Corpse Explosion!**
The explosion sounded almost simultaneously, and the two Stone Demons that had just pounced were blown to pieces on the spot.
The bodies of the seventh-level Divine King Stone Demons could potentially kill an eighth-level Divine King.
Even now, splitting the explosion to kill two seventh-level Divine King Stone Demons was no problem at all.
The Stone Demons' bodies shattered again, turning into pieces of stone scattered all over the ground.
This time, even the laws were blown apart, their souls extinguished, unable to reassemble.
Their proud defense was useless against an attack far beyond their endurance.
With a casual gesture, a piece of stone flew into Lin Moryu's hand.
This piece of stone was from one of the Stone Demons' bodies. If one was used, another had to be replenished.
As for the other body, it was now enveloped in Undying Flames.
Lin Moryu used **[Resurrection of the Dead]**, releasing a ball of Undying Flames to turn the other Stone Demon into a resurrected being.
Soon, the seventh-level Divine King Stone Demon respectfully knelt before Lin Moryu, its massive body like a small mountain.
Lin Moryu casually asked, "Do you know the conditions for the appearance of leader-level monsters in the middle layer?"
"Yes!" The Stone Demon replied in a hoarse voice, giving a definite answer.
Lin Moryu was pleasantly surprised, not expecting to get an answer so quickly.
He didn't believe in coincidences; it was clearly not a secret, and anyone entering this area should know.
After waiting for a few seconds, the Stone Demon remained kneeling, motionless.
Lin Moryu slapped his forehead, realizing he had made a mistake.
The Stone Demon's mind was too simple. He had asked if it knew the conditions for the appearance of leader-level monsters, and the Stone Demon had answered honestly.
But he hadn't asked for the specific conditions, and with the Stone Demon's simple mind, it wouldn't continue to answer.
"Really stupid."
He muttered, not sure if he was cursing the Stone Demon or himself, and then asked, "What are the specific conditions?"
The resurrected Stone Demon immediately replied, "Collect enough crystal cores and combine them. As long as the quantity is sufficient, you can summon a leader-level monster."
Lin Moryu continued to ask, "How many are needed specifically?"
The Stone Demon replied in a muffled voice, "I don't know."
Hmm?
Lin Moryu believed that the resurrected Stone Demon wouldn't lie. If it said it didn't know, then it really didn't know.
"Could there be other factors involved?"
Lin Moryu pondered, feeling that talking to intelligent beings was indeed more interesting.
Of course, talking to normal beings was fine too.
But talking to such a stupid creature was a bit frustrating.
After a few seconds of contemplation, Lin Moryu didn't stop asking but changed his approach, "Is the number of crystal cores needed to summon a leader-level monster fixed?"
The Stone Demon replied in a low voice, "If they are seventh-level crystal cores, more are needed. If they are eighth-level crystal cores, fewer are needed."
Lin Moryu finally understood. It wasn't that the Stone Demon was unclear, but that he hadn't asked clearly enough.
In the middle layer, summoning a leader-level monster required enough crystal cores.
This "enough" didn't refer to the number of crystal cores but the energy contained within them.
As long as the energy was sufficient, a leader-level monster could be summoned.
In the middle layer, there were two levels of monsters: seventh-level Divine Kings and eighth-level Divine Kings.
The crystal cores they dropped were also divided into two levels. The energy contained in seventh-level crystal cores was naturally much less than that in eighth-level crystal cores.
With a fixed energy requirement, using all eighth-level crystal cores would naturally require fewer.
But anyone with common sense would know that hunting eighth-level Divine King monsters was much harder than hunting seventh-level ones.
In terms of cost-effectiveness, it was better to hunt more seventh-level Divine King monsters.
Lin Moryu took out all the crystal cores he currently had, totaling over a thousand.
There were many, but the quality was not ideal.
They ranged from the fourth to the sixth level of the Divine King realm.
These crystal cores were all collected from the demon strongholds in the outer layer.
Through his questioning of the Stone Demon, Lin Moryu discovered more differences between the outer and middle layers.
In the outer layer, the crystal cores obtained from hunting could be used personally and didn't need to be handed over.
But in the middle layer, half of the crystal cores obtained from hunting had to be handed over.
For every two obtained, one had to be handed over.
This one was used to summon leader-level monsters.
This discovery gave Lin Moryu an idea.
He could replicate this method, robbing the demon strongholds in the middle layer and taking their crystal cores for himself.
That way, even if the crystal cores were insufficient, they wouldn't be too far off.
At least it would save him a lot of time.
Lin Moryu continued to ask, "When was the last time a leader-level monster was summoned?"
The Stone Demon answered honestly, "Fifty-nine years ago."
Lin Moryu murmured, "It's been fifty-nine years. The Stone Demon stronghold should have accumulated a lot of crystal cores."
"And it proves that each summoning requires a significant number of crystal cores."
Looking at the still-kneeling Stone Demon, he continued to ask, "How many keys does each leader-level monster drop?"
"Two to three."
Hearing this, Lin Moryu was slightly surprised.
That number was a bit low. It meant that each appearance could grant at most two or three people the qualification to enter the deep layer.
Of course, reaching the ninth level of the Divine King realm wasn't easy.
But the demon race had a large population, and even if the ninth-level Divine Kings were few, there were still some.
Lin Moryu realized another problem, "How many ninth-level Divine King demons are there in the middle layer?"
