Chapter 920

Xu Liao attacked once, but seeing that he couldn't deal with the demonic light, he immediately formed a seal to summon Treasure Lord Bu Er and smashed him down.

Demon Lord Tai Sui was confident that his demonic light was invincible, so he wasn't afraid of being besieged by enemies. Although he had used all his methods, he was still fearless. However, he didn't expect that Xu Liao would have such a method.

Treasure Lord Bu Er naturally rejected all treasures, including Great Desolate Era Treasures, Great Desolate Era Treasures, and even Heavenly Dao Treasures. He could create a world, rendering all spells and treasures ineffective.

Although Demon Lord Tai Sui's demonic light was powerful, it was still a spell. After being smashed by Treasure Lord Bu Er, the demonic light immediately dissipated. Even if he used all the demonic power in his body, he couldn't summon it again.

The lightning tribulation summoned by Xu Liao with the help of the Great Void Golden Flower had already expanded to ten thousand miles. Countless lightning bolts fell down and immediately blasted the Demon Lord's flesh and blood. Xu Liao raised the Extreme Mystic Green Flag and collected it.

After devouring Demon Lord Tai Sui's flesh and blood essence, the Extreme Mystic Green Flag gave off a faint light. Xu Liao was delighted and naturally used more methods. However, this Demon Lord's flesh was also extremely tough, so he couldn't do anything to him for a while.

Just when Xu Liao was attacking with all his strength, a sword light flew over and just circled around, cutting Demon Lord Tai Sui in half. This sword light was as black as ink, and it was cultivated by the Paradise Sword Scripture.

Xu Liao was delighted because his other battle clone had finally arrived.

Demon Lord Tai Sui's body was cut open by the Paradise Sword Scripture, and the Extreme Mystic Green Flag flew out like a living thing. It drilled into the Great Demon Lord's body and kept devouring his blood essence.

Xu Liao formed a seal to refine the twenty meridians. In a flash, he finished refining the twenty meridians and started refining the second restriction, the thirty-six Heavenly Dipper Meridians. This Great Desolate Era treasure did not reject Xu Liao's refinement. Instead, it borrowed Xu Liao's magic power to devour the blood essence without restraint.

Demon Lord Tai Sui was not very afraid of the Paradise Sword Scripture, but he was extremely afraid of the Extreme Mystic Green Flag. After all, it was his accompanying Great Demon Lord Tai Sui's treasure. The Great Demon Lord roared and used its claws to pull the rag out, wanting to tear it apart. At this moment, the Extreme Mystic Mystic Fan, the Extreme Mystic Green Flag, was already in.

The Taisui Demonic Monarch wanted to tear it apart, but the primeval treasure flew into the sky with a swoosh and merged with the Heavenly Abode Sword Light that flew over. The Heavenly Abode Sword Light slashed down and cut open the Taisui Demonic Monarch's body. The Extreme Mystic Green Flag took the opportunity to burrow inside. When Demon Lord Tai Sui wanted to tear it apart, the Great Demon Lord Tai Sui flew into the sky and merged with the Paradise Sword Radiance. The Paradise Sword Radiance slashed down and cut Demon Lord Tai Sui's body. Then, the Extreme Mystic Green Flag took the opportunity to enter.

When Demon Lord Tai Sui wanted to pull it out, the Great Demon Lord Tai Sui transformed into a clear light and escaped from the Great Demon Lord Tai Sui.

Even Heavenly Weapons could transform. The grade of the primeval treasures was far above Heavenly Weapons. Of course, they could also develop spirituality and even turn into living creatures. However, the primeval world was still in its early stages. The primeval treasures were born too early. Hence, they could not activate enough spirituality. If another few hundred thousand years passed, these primeval treasures wouldn't be completely obedient to their masters, and they would act on their own.

Xu Liao knew that the Extreme Mystic Green Flag was so intelligent, but he didn't panic. He just sacrificially refined the Great Amplification Meridian of the third layer of restriction. Now that he was a Perfected Being, the Extreme Mystic Green Flag was very cooperative, and Demon Lord Tai Sui's rich blood was injected into it. Therefore, the refinement of the forty-nine Great Demon Lord Tai Sui's third restriction was smooth.

Xu Liao smiled and stretched out his hand. The Extreme Mystic Green Flag was immediately caught in his hand and didn't dare to move.

Xu Liao spread out the flag. The Extreme Mystic Green Flag was different from before. Although this treasure only had one side, it was unpredictable and had no fixed shape. Sometimes it was square, sometimes it was octagonal, and sometimes it was strange like flowing water.

Xu Liao knew that although the Extreme Mystic Green Flag was called a flag, its essence was a clear light. If it could refine the accompanying demon, it could return to its original appearance. It was known as the Great Demon Lord Tai Sui.

This treasure was said to be invincible. If it returned to its original appearance, it would be a counter to Treasure Master Bu Er, and Treasure Master Bu Er would not be able to restrain it so easily.

However, the Extreme Mystic Green Flag had not been opened yet, and Demon Lord Tai Sui had not refined this treasure. Neither the Extreme Mystic Green Flag nor Demon Lord Tai Sui could resist the suppression of Treasure Master Bu Er.

After fighting with Xu Liao for nineteen days and nights, Demon Lord Tai Sui suddenly became smart. He clenched his hands and feet and desperately activated the demonic light. He finally understood that every time Xu Liao used Treasure Master Bu Er to suppress his magic power, he would send it far away. Then, he would activate the Heavenly Sword Scripture, Great Void Golden Flower, and other treasures to kill him.

There was also the rebellious Extreme Mystic Green Flag, which constantly took advantage of the situation to plunder his Essence Blood and Yuan Qi. But if Demon Lord Tai Sui kept his spirit and qi, he would still be suppressed by Treasure Master Bu Er. However, when Treasure Master Bu Er appeared, all the magic power in the world could not be used, and the enemy could not attack. Only when Treasure Master Bu Er disappeared would there be all kinds of killing methods.

Demon Lord Tai Sui was right. As long as he desperately activated the demonic light, even if he was suppressed by Treasure Master Bu Er for a while, as long as Treasure Master Bu Er was sent away by the enemy, his demonic light could evaporate again. No matter what magic the enemy used, it could be blocked by the demonic light.

Xu Liao did not expect that this great demon would learn to be obedient so quickly. He was secretly surprised, but at this moment, he was not too anxious to kill Demon Lord Tai Sui, because he wanted to continue refining the Extreme Mystic Green Flag. If he killed Demon Lord Tai Sui too early after the battle, this treasure would probably rebel.

The three layers of restrictions were nothing. If the Chaos Era treasure was willing, it might be able to dissolve these restrictions. Unless he refined the fourth layer and started refining the treasure's 72 Dao meridians, then he could be considered to have complete control over it.

Xu Liao was now at the Perfected Person Realm, so refining the Extreme Mystic Green Flag was much more convenient than refining the Chaos Era treasure when he was still at the Daoist Realm.

Xu Liao seemed to be unable to deal with Demon Lord Tai Sui. After fighting with him for a few years, he vaguely seemed to have gained the upper hand. He once again opened the Great Ah Han Reincarnation Sea of Blood Array and drowned Demon Lord Tai Sui in it.

Outside Demon Lord Tai Sui, there were Black Light Sword Qi, Thunder Tribulation, and Blood Light. The three layers of magic power kept grinding. Even though the great demon's defense was unparalleled, he still could not bear it. From time to time, he had to swallow the demonic light to shake off the array and the Thunder Tribulation. He even had to fight head-on with the Grotto-heaven Sword Scripture to prevent his Primordial Qi from being worn down by all kinds of magic power.

The Extreme Mystic Green Flag gained the upper hand, but it could not do anything to this great demon. After all, it was only a treasure. Without someone to control it, it could not unleash its full power.

Xu Liao had used the remaining time to refine more than 30 Dao meridians in the Extreme Mystic Green Flag. However, he knew that the fourth layer of restrictions was enough to control this Chaos Era treasure, but if he wanted to use it as if it was his own arm and not be disobeyed by this spiritual Chaos Era treasure, he still had to go to a higher level.
