Chapter 921

After all, the Extreme Mystic Green Flag was a magic treasure. Although it was full of spirituality, it was not as far-sighted as humans. It instinctively felt that if it could suppress Tai Sui, it would be able to reach a higher level and would no longer be muddle-headed like before.

The more Xu Liao refined, the more power it could borrow. Therefore, in order to suppress Tai Sui, it desperately released itself to Xu Liao, hoping that Xu Liao would refine more.

Xu Liao had refined more than thirty Dao meridians. Although the Extreme Mystic Green Flag's power was still inferior to Demon Lord Taisui's, it could barely resist the demonic light. It turned into a wisp of light and even borrowed the power of the Grotto-heaven Sword Scripture to burrow into the Demon Lord's body. It was not difficult to avoid being caught by the demon.

Demon Lord Taisui tried to use the demonic light several times to destroy the light, but he found that it was impossible. Although the light was flexible, it seemed to have no limit. No matter how the demonic light used it, it could not suppress this primeval treasure that was born from the same source.

Taisui Demon Monarch was careless and was once again suppressed by Treasure Master Bu Er. This time, Xu Liao did not retreat. The Great Virtual Essence Artifact transformed into a battle clone and personally attacked Taisui Demon Monarch with a punch.

The Great Virtual Device could open up countless Grotto-heavens, but it could also destroy them. The Grotto-heavens had the power of destruction, and it could burst out infinite destructive power that could crush all laws in the world.

Although Demon Lord Taisui's body was strong, it was still shattered by the fist power that contained the power of destruction. It was cut into thousands of pieces by the crushing power of the Grotto-heavens.

The Great Virtual Device had devoured Ancestor Dongxuan and refined it to great success. It had refined 51 True Meridians, and its power was endless. It was far from the battle clone formed by the Ten Incarnations Celestial Demon Splitting Art, which only had a few True Meridians.

The battle clone formed by the Great Virtual Device might be weaker than Demon Lord Taisui, but it was proficient in countless methods. If it was a one-on-one fight, it would not be afraid of this old demon. Moreover, Demon Lord Taisui's aura was declining.

The punch was perfectly timed, and it was when the Taisui Demon Lord's aura was at its weakest. If this Great Demon Lord was at his peak, he could immediately activate the demonic light to shatter countless Grotto-heavens and reunite his demonic body. However, the Taisui Demon Lord was powerless at this moment. If he wanted to shatter the Boundless Lesser Heavens, he would need at least half a day's time. But, how could it allow him to have half a day's time?

The Extreme Mystic Green Flag did not hesitate to enter one of the Grotto-heavens. It immediately devoured the pieces of Demon Lord Taisui's body that were sealed in the Grotto-heavens and benefited from it. The treasure then entered another Grotto-heavens …

Xu Liao's progress in refining this primeval treasure skyrocketed in an instant. One Dao meridian after another was refined. After a few days, when Demon Lord Taisui finally shattered the Grotto-heavens and reunited his body, the Extreme Mystic Green Flag had already refined 72 Dao meridians, allowing Xu Liao to complete the refinement of the fourth layer of the restriction.

Demon Lord Taisui was indeed an old demon who was about to become a Skyfiend. Although he was seriously injured and his aura was declining, his cultivation did not drop much. He knew that if he continued to fight, he would not be able to gain any advantage. He hurriedly used the demonic light and wanted to soar into the sky.

Xu Liao hurriedly pressed down, and a pagoda came crashing down, sending the Great Demon back into the Great Ah Han Reincarnation Blood Sea Formation.

The battle between the two sides was getting more and more intense. Xu Liao had also used all his skills. The combat doppelganger formed by the Great Virtual Device used several primeval treasures, except for the Primeval True Treasures and Taoist Treasures, which were not qualified to participate in the battle.

The Great Virtual Device, the Four Forbidden Qi Towers of Xuandu Utmost Truth, the Nine-Nine Dispersing Gourd, Treasure Master Bu Er, and the Extreme Mystic Green Flag!

With a total of five Primitive Supreme Treasures, Tai Sui Demon Monarch was beaten down to the ground. Both sides fought hard for dozens of days. The doppelganger formed by the Great Virtual Treasure suppressed Tai Sui Demon Monarch with the power of Treasure Master Bu Er. Then, it smashed the Demon Monarch's body with a punch.

The combat doppelganger formed by the Great Virtual Device combined with the treasure was also known as the Body Treasure Master Bu Er!

He himself was formed by a magic treasure, and the power of his body was the power of the magic treasure. Therefore, he could not be restrained by Treasure Master Bu Er. Moreover, the level of the Great Virtual Device was far above that of Treasure Master Bu Er, and it also had infinite destructive power, which could destroy all laws in the world. Therefore, it could resist the influence of Treasure Master Bu Er.

However, once the crushing power of the Grotto-heaven left his body, it could not withstand the suppression of Treasure Master Bu Er.

Therefore, after Treasure Master Bu Er suppressed Demon Lord Taisui and let the physical body of the Great Virtual Device attack, he had to withdraw the power of Treasure Master Bu Er. Otherwise, the Grotto-heaven power of the Great Virtual Device would be destroyed by Treasure Master Bu Er after it left his body.

Relying on the Grotto-heaven power alone could not trap Demon Lord Taisui for too long, but it was enough for the Extreme Mystic Green Flag to take the opportunity to devour Demon Lord Taisui's broken and sealed body.

Even in the future Vast Extreme Heaven or the era of the 33 Heavens, such as the Primordial Immemorial Age, Demon Lord Taisui might have a fierce cultivation, but he did not have the corresponding wisdom. He was far inferior to the Demon Gods of the future.

If it was a Demon God of the future, such as the Lord of the Xu Mansion, Xu Liao would not be able to defeat this Great Demon Lord even if he had five Primordial Treasures and a Heavenly Dao Treasure.

If the two were to fight, the Lord of the Xu Mansion could easily suppress Xu Liao and take away all his treasures. Even if the Lord of the Xu Mansion were to appear, he would not be able to change the result.

When Xu Liao used this tactic for the seventh time, the Extreme Mystic Green Flag suddenly shook violently, and a clear radiance spread out, covering the sky and covering thousands of miles. Unexpectedly, it gave birth to a great spirit.

Xu Liao hurriedly used the Single Treasure Master to suppress Demon Lord Taisui. He did not participate in the battle himself. The two Combat Doppelgangers worked together to activate their Dharma power, constantly refining and injecting Dharma power into it.

About ten days later, the Extreme Mystic Green Flag suddenly tore open, and the clear radiance scattered, covering the two Combat Doppelgangers with a layer of clear radiance, giving the two Combat Doppelgangers different insights.

Just like the Great Virtual Artifact, this Chaos Supreme Treasure was refined to the fifth layer of restriction, and a true meridian was opened.

The Extreme Mystic Green Flag was upgraded. Xu Liao used the Combat Doppelgangers of the Great Virtual Device to blast away Demon Lord Taisui for the eighth time. It was not so easy for this Great Demon to reform his Demon Body. The Extreme Mystic Green Flag actually devoured one to two percent of its power, refining two real meridians.

As time went by, the battle gradually came to an end.

Xu Liao's two Combat Doppelgangers, together with the Extreme Mystic Green Flag, endured for a few more years. When the last demonic light dissipated, the clear radiance of the Extreme Mystic Green Flag almost covered the world, vast and boundless.

The true appearance of the Primordial Immemorial Treasure was restored.
