Recently, I have been sorting out the information, if there is any error, please reply here.

Arnold walked briskly through the underpass.

Alder had a secret basement whose location was known only to successive city lords, so Arnold didn't even tell Xiu, and in fact there was no need to tell her. The purpose of this basement was not to allow the lord to leave Alder safely or survive the disaster in the event of a disaster.

So there is only one exit in the basement, and there is no food or water stored in it, only one thing.

Arnold pushed open the basement door, and a pungent smell crept into his nostrils. He carefully took out a night pearl from his arms, and suddenly, a faint blue light barely illuminated about two meters in front of him. Using the Night Pearl for lighting was definitely the most extravagant and least efficient method, but he had no choice.

Because in front of him was a mountain of black powder.

Long ago, before alchemists invented source stones, they used black powder to fight powerful dragons. Black powder is immensely powerful, but its instability often puts the hunters of the hall in danger of being attritioned before encountering dragons. It wasn't until the source stone was invented that the source of fire replaced black powder in an instant, and this once powerful and dangerous weapon naturally withdrew from the stage of history.

But back then, Alder produced huge quantities of black powder, which could not be destroyed overnight. So the current lord of the city stored all the black powder in the dark basement. Arnold once asked his father how much black powder was stored in it, and his father replied only one sentence:

"Enough to raze half of Alder to the ground. ”

Later, he learned that there was not only black powder stored underground, but also thousands of sources of fire. Those sources of fire were placed in many places on the periphery, and if the black powder was ignited, it would set off a huge wave of heat that would detonate hundreds of sources of fire and destroy half of Alder in an instant.

Unbeknownst to the people of Alder, half of Alder was built on gunpowder.

The lord of the castle who built it all hopes that one day when Alder is facing ruin, he will be able to drag his enemies into the abyss with him. Arnold had always believed that the guy was crazy, and he had told himself countless times that he would never ignite the black powder here anyway, but now-

Arnold clenched his fists tightly, and his mind had made a decision.

With such a powerful dragon army, even the imperial capital with the [Noah's Line] could not hold it. Not to mention that the Dragon Emperor Mussolini has not yet appeared, in this case, he must leave the Thunder King Naash and half of the Wyvern in Alder forever.

Hundreds of tons of black powder and thousands of them can even crush the source of the dragon exterminator. Arnold had hoped to deal with the Dragon Emperor here, but now that the Dragon Emperor had not appeared, he could only turn his goal to eliminate a king.

Three years ago, Lord Cassius, the Sunflower King, told himself that if he wanted to kill a king, he would have to pay the same price.

Fortunately, Xiu's location was not affected by the explosion. Once he kills Na Ash, the guards will follow their orders and take the survivors of Xiuhe to the imperial capital. At that time, the dragon clan folded the embers, and the imperial capital still had the [Noah's Defense Line] and the last high-level hunters of the Thorn Lord and the hall, and the humans would not necessarily lose.

Just as Arnold was thinking, there was a sudden tremor in the earth. Before he could react to what was happening, countless pieces of rubble were falling, and the entire basement was shaking. He clung to the doorframe so hard that he didn't let himself fall, and the next moment the roof collapsed, and the slightly damp air came through the crack.

Arnold saw the dragon king Naash, and he finally struck, and the whole dragon seemed to be bathed in thunder and lightning. Arnold knew he wouldn't stand a chance if he didn't make a move, so he grabbed the source of fire in his pocket and prepared to throw it at the mountain of black powder.

At that moment, he heard Na Ash's wail, and he looked up and saw that Na Ember had fallen from the sky and landed with a thud.

Arnold's eyes widened, his face full of incredulity.

Someone hurt Na Ember?!How is it possible?!

......

Ian's knife-wielding hand trembled slightly, and his eyes were red as if they were oozing blood. His clothes had long been tattered, and there were two or three striking wounds under each crack, and there was a trace of white gas oozing from the wounds, and [Iliad Living] was frantically repairing his body.

Blood dripped down from the tip of the dragon's sword. It wasn't his blood, it came from Na Ash, the King of Flame and Thunder.

The battle between him and Nathan was simple and brutal, just like the battle he had with Nathan in the past, condensing time through [Time and Space] and taking the opportunity to attack. But [Time and Space] can't hold Na Ember for too long, because Na Ember is no longer the Na Ember it once was, and after fusing the power of Naga, the Lord of Fire, its power has reached an unprecedented height, at least the former Nathan is far from being able to compare.

The arc around it will be paralyzed once it touches half of its body, and its mobility will be greatly slowed down, so that Na Ember will have a chance to fight back. In this way, he left dozens of wounds on Na Ash's body, but it was harmless, and the wounds that Na Ash left on his body were almost fatal, but they were made up for by [Endless Life].

The two of them are like two wild wolves with no fighting skills, competing to see who has more physical strength and who can persevere better. Despite the [Endless Life], Ian didn't think he would be able to hold out until the end, [The Endless Life] was frantically devouring his body, and even the [Time and Space] would be affected.

It has to be done quickly.

Thinking of this, he smeared the source of dragon slaying on the blade of the dragon slash. He intends to stab Nathan in the heart with a knife smeared with the Source of the Dragon Slayer to deliver the fatal blow.

Standing on Alder's tallest building, Naember watched as Ian smeared the source of the dragon slayer on the dragon cut, but didn't make a move. This had to make Ian wary, and he was ready to enter the [plane] to complete this move.

But Na Ember never made a move, as if he didn't care about the source of the dragon slayer at all, it stands to reason that as a dragon king, it should easily feel the power contained in it. It's like Nathan at the beginning, who refused to let Ian get close no matter what.

Although he couldn't figure it out, Ian still completed the preparations, and next, it was the final fatal blow.

However, at this moment, Na Ember suddenly raised his neck high.

At this moment, a strong sense of uneasiness welled up in Ian's heart, and he no longer hesitated, grabbed the dragon cut and ran towards Na Ash, the power of [Time and Space] dragged Na Ember at the same time, making it slow down with every movement. But this time, Ember broke free from [Space] in the blink of an eye, and it spread its wings and soared into the sky, dodging Ian's fatal blow.

Ian threw himself into the air, and the intense sense of unease intensified.

Na Ember opened his mouth and lowered his head.

Pillars of dark red fire erupted from its mouth, just like Naga back then. But unlike Naga, the pillar of fire was accompanied by a fine arc of electricity. It was like a dark red spear falling from the sky, piercing the earth fiercely.

For a time, the heavens and the earth changed color.

Hemispherical flames and lightning spread in all directions, and at the same time, the black powder underground was directly detonated!

Half of Alder was reduced to nothing in an instant, and those who were touched by the flames turned to dust before they could shout, along with the dragons. They struggled to get out of the blast area, but in the face of the scourge of dragon flames, they were weak like reptiles, devoured in the blink of an eye.

The alchemical city of Alder, a centuries-old ancient city, finally collapsed at this moment.
