After returning triumphantly from the Nine Alliances Domain, Su Yuan and the others were not too happy. However, being able to kill the Scale King at one time allowed Su Yuan to come into contact with the strength of the Four Fierce Men for the first time, so it can be said that if it weren't for the help of the mind reader, I am afraid that Su Yuan would have to pay a huge price to defeat the Scale King.

After all, there are eighteen treasure immortal crystals in the body of the Scale King, and it is indeed difficult for Su Yuan to break through the defense and injure the Scale King.

And the King of Scales is in the four fierce, ranking last.

Among the four fierces, the strongest is the Stone Maiden, the Heavenly Demon Moth, this time it is the Rat Emperor, and finally the Scale King.

Su Yuan fought with the King of Scales, and he was probably able to figure out the ability of the other three murderers. The Scale King is already very difficult to deal with, and the other three murderers are probably even more difficult.

Moreover, the other three murderers were not as reckless as the Scale King, but hid in the forbidden area, secretly recovering from their injuries, and waiting for the opportunity to rise.

And the Scale King was even bolder, and he actually wanted to directly devour the aura of the Nine Alliance Domain, which caused Su Yuan and others to take action and kill the Scale King.

In order to deter the other four murderers, Su Yuan directly hung the corpse of the Scale King on the city wall.

Boom –

"That guy from the Scale King actually planted ......"

In the dark forbidden area, a low and strange voice came, and in the endless demonic qi, a red pupil appeared, which seemed to penetrate the void and fell on the city wall.

The scales of the scale king's body were stripped away, and he was bloodily hung on the city wall!

Su Yuan wanted to warn the four murderers, this is the final fate of the traitor, as long as he kills one, his body will be hung on the city wall.

"This guy is arrogant by nature, and his strength has not fully recovered, which can be regarded as cause and effect. ”

In the other forbidden area, there was also a voice, low and evil.

The three murderers were vigilant, they also knew that Su Yuan was a powerful opponent!

After returning to the Great Yuan Dynasty, Su Yuan immediately ordered three things, the first thing was to continue to look for the traces of the Pu Demon Tree, the second thing was to monitor the movements of the three forbidden areas, and the third was to find the whereabouts of the Jiuyin Yellow Spring. As for why he was looking for the Nine Yin Yellow Spring, it was to reforge the Emperor Sword.

The Sky Setter Sword was broken off by the scales of the Scale King, and it was completely scrapped. The magic sword still needs to be warmed, and the seven-star dragon yuan does not have a sword soul yet, and Su Yuan still has a broken emperor sword in his hand.

Sword Forger Li Lao can repair this sword, but he needs a Nine Yin Yellow Spring Pool.

During this period of time, Luo Shen and others divided their troops, monitored the forbidden area, and looked for Huangquan Pool.

Su Yuan, on the other hand, is in retreat.

In the stone chamber, wisps of blue flames floated, and the light was projected on the stone wall, like countless ghosts moving.

Directly in front of it, there was a furnace ding, and inside the furnace was countless scales. These scales were exactly what Su Yuan got from the Scale King.

Su Yuan's eyes were blazing, he pondered for a long time, and then his slender fingers took out one of the scales from the furnace to check it.

Among the scales, there was a black glow.

Through the mind-reading pupil, Su Yuan could clearly see a black crystal.

Su Yuan raised his palm and cast a spell to take out the Treasure Immortal Crystal from the scales. A black crystal fragment landed in his palm, and at the same time, Su Yuan took out another Treasure Immortal Crystal.

On the palm of his hand, there were two Treasure Immortal Crystals, one of which was black, and the other was his own Treasure Immortal Crystal, which was transparent crystal white, one exuded an evil aura, and the other was crystal white and pure.

And the Treasure Immortal Crystal of the Scale King is already a blackened Treasure Immortal Crystal. Blackening is not the same as pollution, blackening Baoxian crystals must start from the Baoxian tree, while pollution can only have an effect on the surface of the crystal, while blackening needs to start from the root.

"Lord Treasure Sense......"

At this time, Su Yuan fell into deep thought, and his eyes suddenly narrowed, and they became weird.

He remembered that the Scale King called the Treasure Immortal Tree the Treasure Immortal Master, and besides, this Scale King had a total of eighteen Treasure Immortal Crystals, combined with these, Su Yuan wondered if this Treasure Immortal Tree had taken refuge outside the territory.

If that's the case, I'm afraid it's not good.

Or, there is also a possibility that the Treasure Immortal Tree is clearly hoodoo and blackened.

All in all, this bold guess is extremely bad news.

"I don't know if I can restore ......"

Su Yuan came back to his senses and looked at the Bao Xian Jing with black gas in his palm. Such a crystal has a powerful increase in strength. If Su Yuan wanted to cultivate the Treasure Immortal Body, he needed a large number of chips.

Therefore, even if these crystals are blackened, he wants to try to get rid of the evil qi.

Thinking like this, Su Yuan's sleeve robe waved, and the spiritual power wrapped the blackened Treasure Immortal Crystal and fell into the furnace, and then, Su Yuan's pupils flickered, projecting two flames.

Laugh at!

The flames burned rapidly in the furnace, and the Flame of the Burning Spirit burned its scales violently. Su Yuan's idea was to use the flame to burn the dark matter, so as to restore the purity and immaculate nature of the crystal.

The flames whirred and burned, however, in the midst of the emerald flames, the black crystals still shone brightly, as if the Soul Burning Flame had no effect on them.

And the power of the Soul Burning Flame is not comparable to ordinary flames, however, this ordinary burning cannot remove the dark matter.

"The Flame of the Soul is useless......"

Su Yuan frowned, his expression solemn.

He underestimated Dark Matter......

However, if you can't purify the Treasure Immortal Crystal, this Treasure Immortal Crystal cannot be used. Dark matter contaminates spiritual power and is impossible to put into the body.

Su Yuan secretly said that it was a pity, a full seventeen Treasure Immortal Crystals, which was a huge fortune.

After pondering for a moment, Su Yuan took out another jade bottle, he opened the bottle, and a golden cloud steamed up. On top of the bottle, there is the holy water of Yaochi, due to the chaotic situation, Su Yuan has not used the holy water to restore the domain soil for the time being.

He took out some holy water and gently introduced it to the stove.

Laugh at!

The two of them reacted violently, one good and one evil, but to Su Yuan's disappointment, the Yao Chi Holy Water was also useless.

"Perhaps, there is another way. ”

Su Yuan's eyes lit up slightly, but this method obviously could not be realized for the time being.

In the midst of this vast world, there is a powerful artifact called the Azusa Emperor Bow. This imperial bow can shoot purifying arrows, which can purify all evil forces. However, this artifact is hidden in a superpower.

Right now, Su Yuan doesn't have time yet.

In the midst of contemplation, there was a noise outside the door.

"Come in......"

Rumble –

The stone door opened, and an old man stepped in.

This old man is none other than Li Lao.

"Congratulations to the Lord of the Emperor, there is already news of the Nine Yin Yellow Spring Water, and the recasting of the Yellow Spring Emperor Sword is just around the corner. ”

Li Lao arched his hand.

"Oh?"

Su Yuan's eyes lit up, since this is the case, he wants to go out and get the Huangquan Pool and rebuild the sword.

"Elder Li, can these scales be used to forge a sword and enhance the strength of the sword. ”

Su Yuan waved his robe, took out a piece of scale, and handed it over. The Treasure Immortal Crystal within the scales was taken out, and the demonic qi was incinerated by Su Yuan......
