Overlord: Start from the Goblin Lair.

"At least we have reached an agreement on this matter." Crestol breathed a sigh of relief. He was really nervous just now. If Ron didn't listen to his explanation at all and insisted on sending him to the Heir of God, the whole situation would definitely be worse.

"I only have one question," Ron stared at the crystal dragon, "Why did you make such a bet with that heir of God? I have fought with him before - barely - but he was far beyond my ability to deal with, and you... could it be that you can shake down an ancient dragon?"

Apart from this, Ron really couldn't think of how Crestor could win this bet.

"Unfortunately, not yet." The Crystal Dragon grinned, seemingly laughing, but Ron could not feel any warmth in his smile. Even when Exuri's skull-shaped head smiled, it was more benign than this guy's. "But you know what? We Crystal Dragons have a unique advantage in astrology divination."

"I divined that you have a trump card that can restrain the giant - it's not the arrow, but the power that truly belongs to you."

Ron was so angry at his words that he laughed: "That's really weird! You can predict something in me, but I don't know it myself? What the hell are you predicting?"

"Impossible," Klesto looked at Ron firmly, his mirror-like eyes seemed to see through Ron inside and out, "You must have such power. The astrology may not be accurate, but you and I are face to face now, and this feeling is very strong in me!"

"You have a kind of power that carries an aura close to that of a god! It's not enough to rely on it to ascend to the throne of a god or to fight against a god, but it's more than enough to deal with the heir of a god, or at least to contain him!"

"Think again!"

The crystal dragon was wrapped in the shining power of positive energy. His words seemed to have the power to make people believe in him. Coupled with his firm tone, even Ron was shaken at this moment and began to seriously think about whether he really had such power.

Related to gods... Grey fog? But that didn't belong to him. It was the power of the Final Law. Ron could only use it when that being wanted to lend it to him. Usually when facing powerful undead creatures.

The Frost God's heir is a living creature.

If he wanted to borrow Gracia's power, as long as he was willing to sign a contract, the Grand Duke would definitely be happy to give it to him, but Ron was unwilling to become a supporter of the devil, and strictly speaking, that could not be considered his own power. Just like the gray fog, it was just some kind of "prepayment" or "alms".

Then there is only...

A strange rune appeared in Ron's palm. Its appearance was accompanied by a faint black mist and a bloody smell, but these were completely unimportant in Crestos' eyes!

This rune has a breath close to that of a god! This is it!

"This is... the 'Dust Rune' of the 'Chisel-Tooth Pact'! There's no way I can mistake this!"

Chisel Tooth Pact? Dust Rune? Ron looked at the crystal dragon in confusion, its expression of excitement and vigilance, and its expression of fear and caution, trying to confirm whether the big lizard was playing tricks on him.

"You don't know? Ah, that's right. If you haven't started your multiverse journey yet, how would you know?" Klesto was startled at first, then he showed a look of realization, "The Chisel Tooth Covenant is not an organization in our world. Although this dragon faction has expanded to dozens of planes, their teeth have not yet 'bite' the edge here. It's normal that you don't know." "I know that you dragons divide different camps by color, metal, gemstone, etc., but I have never heard of 'Chisel Tooth'." Ron noticed that the other party was observing the rune, so he tried to make it clearer. After all, this Klesto seemed to know something about it.

"Of course, of course, the dragon faction you mentioned is one of them," the crystal dragon nodded, "but as a large and powerful group, dragon factions are not divided into only this way."

"In the endless multiverse, metal dragons may form five metal knight orders with different ideals but the same goal; different types of dragons may form the Scale and Claw Alliance for the same goal; an extremely powerful dragon may become the overlord in his world and lead all dragons; different breathing methods may also create specific groups. In addition to these, there is another one: the participants all agree on one aspect of the dragon's nature - scales, teeth, claws, wings, and eyes, representing endurance, ruthlessness, brutality, speed, and cunning respectively."

"The Chiseltooth Pact is one such faction, whose members believe that dragons should rule over other races ruthlessly and harshly, and the Dust Rune was created to achieve this goal."

"These runes form a special language system. Only the core members of the faction can fully understand their meaning and exert their full power. The peripheral members can only read and write but do not understand their true meaning. As for the creatures under their rule, they can understand the meaning conveyed by the power of the runes, but they will never be able to learn to read and write in their lifetime."

"Faction members will certainly not teach these runes to the ruled creatures, and the ruled creatures are unable to clearly and accurately express the meaning of the runes. This system ensures that the core demands can be clearly and accurately implemented without any tampering or distortion."

As Klesto spoke, his eyes were still fixed on the rune in Ron's hand: "Of course, these rules only apply to creatures within their jurisdiction and members who have joined them. They do not apply to a human who has never even heard of them - do you understand what I mean, friend?"

"I can only tell the Dragon Language and Infernal Language parts from it, but that's obviously not all," Ron frowned, "I have no way to apply it."

If Ron could have cracked it, he would have put this rune extracted from the blood of the Aikthuri into practical use long ago.

"It doesn't matter." Upon hearing what Ron said, the Crystal Dragon became even more excited. "Tell me! Tell me what it means! I can complete it for you!"

"Oh my God, ever since I passed through their territory by chance during a trip, I was forcibly recruited as an external member. If it weren't for an accident, I would have spent my entire life there! After escaping from there, I have always wanted to give them a little return, but I never had the chance! This time I finally got the chance!"

"'Scales', 'Thunder'." Ron read out the two different meanings of the dust rune in Dragon Language and Infernal Language respectively. Before he could ask Crestor whether he could gain anything from these two simple words, the Crystal Dragon had already begun to roar towards the sky.

On his scales, positive energy and light energy were being rapidly transformed into arcs filled with danger and destruction, leaping across his huge dragon body!
"I understand! I understand!" Crestol laughed in surprise and joy, "You idiots! I am Crestol! You can't restrict me at any level! Dust Rune, I have already mastered one of them -"

"Kala——"

As Ron stared in amazement, as the arcs on the crystal dragon became more and more violent, a bolt of lightning was pulled down from the sky and accurately struck the horn on his head. The surrounding arcs immediately went out of control and swallowed up the adult dragon in an instant!

When Ron opened his eyes again and his vision recovered from the scorching white electric light, Klesto fell in the surrounding ruins in a mess like charcoal. His dark eyes saw Ron's gaze. He seemed to want to say something more, but he only spit out a cloud of black smoke with crackling static electricity, accompanied by a sound -

"Hiccup!" (End of this chapter)
