By the way, Harry, you said just now that you know the secret story of the human-dragon war, what is it?" Kiru asked as he remembered the real human-dragon history that Harry had just said.

"Oh, what I was about to say was all you hurt me off-topic!" Harry seemed a little absent-minded.

"I ......," Kiru said with a wry smile helplessly.

"Okay, okay, let me tell you, in the first battle, the facts are obvious, the master's strength is still good, he cut off the white dragon's 4 dragon scales, and 'provoked' the dragon, and the result was a miserable rest for a lifetime. The white dragon is actually the weakest of the dragons, and I suspect that the white dragon is still a young dragon, and the dragon scales are not fully grown, so the man will break 4 dragon scales. In the second battle, 3 people fought the red dragon for 2 hours without hurting a single 'hair' of the red dragon, which also shows that the strength of the dragon is not comparable to human beings, and I deduced from this that the white dragon is still underage. As for why the Red Dragon was seriously injured at their hands in the end, it was because someone had taken a shit trip and stabbed the Red Dragon's scales!" Harry shook his head and analyzed triumphantly.

"Reverse scales?"

"That is, the cover 'door'!"

"Cover the 'door'?"

“...... That's the ......."

"????" Kiru still does not understand.

"Weakness, you idiot!" Harry almost cried out.

"Dragon's weakness?" Kiru had never heard of dragons' weaknesses, immune to magical attacks, and superior physical defense, otherwise why had humans never defeated dragons?

"Dragons have almost all magic immunity, and physical defense is close to invincible dragon scales, if such a creature is not weak, wouldn't it be invincible in the world?

"Maybe they prefer quiet?" Kiru thought for a moment.

The reason why dragons have always avoided large-scale conflicts with humans is that humans are super-intelligent creatures, as the saying goes: if you walk a lot at night, you will always meet ghosts...... Once the dragons 'exposed' their weaknesses in the conflict with humans, then the dragons will not be able to maintain their superiority over humans, and may even be in danger of extinction. Harry said.

"What weakness is so serious that it would wipe out the dragons?" Kiru asked, incredulous.

Once there is a large-scale conflict between humans and dragons, there will always be dragons that will be attacked to the weak point, once humans know that dragons have such a fragile weakness, the dragon's advantage over human beings to suppress 'sex' no longer exists, and as intelligent creatures, human beings will fully grasp their own advantages to fight the dragons, and then the time for the dragon clan to be wiped out is not far away! Get a dragon whip to play around, well, why are you looking at me with such strange eyes? Don't think about it, a whip made of dragon tendons, referred to as a dragon whip. And then go and kill a giant dragon, the dragon's reproductive ability is already low, how many dragons can be left after killing and killing like this?"

"Is that so?"

"Hmph, you suspect that no one can doubt me who is wise and powerful! Those three masters were killed by the three dragons sent by the dragon clan less than a month after injuring the red dragon, do you think it was just revenge as the record says? The fact is that the dragon clan wants to cover up their weakness, because it is not clear who killed the red dragon, so they simply killed them all. Because the sword that kills the red dragon's scales will obviously feel a different defense from the rest of the body covered by the dragon scales. History records that the master said that he stabbed the red dragon with a super-level explosion, whether he wanted to cover up the secret he knew or really thought that he had divine help, and the truth of this incident after his death was also covered up. It is precisely because of this incident that the dragons no longer treat humans unscrupulously, and many sources can prove that since then, the number of times dragons* have harassed humans has greatly decreased. They're scared!"

"That seems reasonable, but my lord, what does the scale look like?" asked Kiru.

"It's like dragon scales. ”

"How can you tell the difference? I see that the scales of this black dragon all seem to be the same. Kiru asked, glancing carefully at the behemoth in front of him.

"I don't know, I'm not looking for it!" Harry waved his hand, making a nonchalant look.

"......" Kiru was speechless for a moment.

"After listening to me, I'm asking if it's okay, the third battle is obvious, that master and Li Yuanba are not the opponents of the green dragon, when Li Yuanba was about to be killed by the green dragon, I don't know why he was saved, I think maybe it was the other dragons of the dragon clan who came to pick up the green dragon, because the green dragon did not continue to plague humans after that. Li Yuanba was ashamed to mention this humiliating battle, so he did not tell others the details of the battle. In the end, the battle 20 years ago was even more of a joke in the joke, I estimate that the 10 masters didn't even hurt the golden dragon with 'hair', oh no, the dragon didn't have 'hair', it was the scales that didn't hurt the golden dragon. The Golden Dragon is the royal family with high intelligence among the dragon clan, and it is the wise among them who thought that conflict with humans could lead to the disaster of the dragon clan, so he restrained the dragon clan from provoking humans. Therefore, the golden dragon did not want to kill the master of the human race to avoid a greater feud, so the "Non-Aggression Pact between the human and the dragon" was born. However, this contract is clear (to be continued, if you want to know what is going on, please log in.,Mobile phone users log in to ap.,More chapters,Please log in to 16k literature network to read!) is obviously unequal。 First of all, humans will be besieged and killed when they go to the dragon territory, which fundamentally ensures that the secrets of the dragon clan will not be easily discovered. If dragons appear in human territory, humans can't take the initiative to provoke them, and of course dragons are not allowed to wantonly hurt people and destroy things. This treaty ensures that the dragon clan can move relatively freely on the mainland, and they don't have to worry about humans encroaching on their territory, which is a lot of money!"

"But doesn't the record say that the 10 masters defeated the Golden Dragon and 'forced' the dragon clan to sign an agreement?" Kiru asked.

"You don't want to think about it, how can the victor sign such an unequal treaty? The only benefit that humanity gets from this treaty is that it doesn't have to worry about the dragons, but the reality is that the dragons rarely bother humans in the first place. Harry expressed disdain for Kiru's ability to understand.

"But the dragon doesn't do any good, does it?" Kiru still didn't understand.

"On the surface, the dragon did not get any benefit, but from the actual point of view, the dragon has been overwhelming humans since then, after all, in the hearts of humans, the dragon is almost invincible. If you think about it, if the dragon really makes trouble in human territory, who would dare to take the treaty and theorize? Harry couldn't help but sigh, "Trouble-making dragons can be killed by humans according to the treaty, but who has the ability to slay dragons?

"Harry, how did you know so much?"

"Do you know what reasoning is?" Harry's new nouns were obviously numerous, and Kiru was a little overwhelmed.

"Look at your stupid way you don't know, let's put it simply, it's just guessing!" Harry could only explain.

“...... It seems to make some sense to guess. Kiru nodded.

"Hmph, of course, I'm not 'guessing', I have consulted a lot of book records, learned enough details, and then strung these details together, and finally came to a logical conclusion. Of course, since I happened to know that the dragon might have reverse scales, I was able to deduce the result from this, and others didn't know, so even if I knew so many details, I couldn't think of going there. Hahaha!" Harry chuckled smugly.

"Harry, you mean, you used the clue that the dragons have reverse scales to deduce that the dragons have reverse scales?" Kiru suddenly realized that Harry's reasoning didn't seem to be too clever.

"How can I say that!, I must have made a reasonable hypothesis, and then proved the rationality of this hypothesis by reasoning, which is a very clever method of argumentation!" Harry didn't feel his voice louder.

But there's no evidence to prove that this assumption is correct. Kiru muttered.

"Proof, you'll see it soon!" Harry smirked, deliberately 'making noise' to attract the mercenaries who were fighting.

The mercenary group over there has been a heated fight with the black dragon, the black dragon really doesn't seem to have any strength, just in the passive defense, and did not take the initiative to attack, this behavior undoubtedly greatly deepened the confidence of the old Hart and the Drow mercenary group, 15 people fought hard to eat 'milk' in a vain attempt to break the black dragon's defense, so that they could finally kill the black dragon and win the title of dragon slayer warrior. But after attacking for dozens of minutes, there was not a single scar on the black dragon's body.

Suddenly noticing that there were other people nearby, everyone couldn't help but be shocked! Although they hadn't made any achievements yet, they had already regarded the black dragon as a trophy in their hearts, so they were naturally worried that someone would come to snatch it.

"Who's there?" said Old Hart leaped out of the battle circle and looked in Harry's direction.

The rest of the Drow members also stopped, perhaps because the black dragon did not attack, so everyone's vigilance was not too high now. Drow's 12 high-ranking warriors continued to surround the black dragon, which had now landed on the ground, and it didn't react much after the mercenaries stopped, and had no intention of escaping or attacking. Kidd and Qin Lan also walked towards them, and the Wild Wolf Mercenary Group in the distance also surrounded them.

"Hehe, you go on, we're just passing by to make soy sauce~" Harry didn't feel the slightest annoyance at being discovered, but greeted the mercenary happily, "This must be the veteran master of the mercenary world, Elder Hart, I have been looking up for a long time! I have long heard that Elder Hart of the Mercenary Guild is a number of masters, and it is really extraordinary when I see it today." The Kidd Regiment Leader of Zhuoer and His Excellency Qin Lan's 'Ghost Sword' are also really amazing, and they really deserve to be the number one mercenary group in the world. Without blushing at all, he threw away the overheard message, still smiling on his face.

In the face of a burst of praise, the three of them couldn't help but feel proud. Looking at the other party again, a mid-level warrior and a young level 6 magician don't seem to be a threat, even if they want to pick up leaks on the side, they are not qualified. But the two of them suddenly appeared, and they were still a little skeptical, "Who are you and how did you get here?" asked Kidd.

"We're just two little mercenaries, passing by here to complete a mission. I don't want to see the three top masters fighting the evil black dragon, and I really admire the three of them, so I stopped and watched. Afraid of disturbing everyone's battle, he hid on the side and waited for the three dragons to succeed in slaying and witness the first feat in human history. I don't want to be 'excited' for a while, but I still shocked everyone, I'm really sorry, I'm sorry. Harry said with a on his face.

The wolf recognized Harry and Kiru, but he didn't understand why Harry and Kiru were here, could it be that they were coming at him?
