“Stone Fire.” Jian Wushuang called out to Ruler Spark, “I have a direction in my mind. Can the killing move of the Divine Demon Heaven Suppression Formation that I just displayed be combined with the wave light sword formation that I created?”

“Combine with the Sword Formation?” Ruler Spark was stunned and then nodded. “Master, the killing move that you just performed is still performed by the Divine Devil Heaven Suppressing Formation. It’s a method of formation. Since it’s a formation, in principle, it can be combined with other formations. Of course, it can also be combined with master’s sword formation. It’s just that the process is more complicated. Master may need some time to complete it.”

“It doesn’t matter if it takes me some time. As long as it doesn’t take thousands or tens of thousands of years, it’s worth trying,” Jian Wushuang said.

“It won’t take thousands or tens of thousands of years. After all, you have completely mastered the Divine Devil Heaven Suppressing Formation. I think master will be able to combine his sword formation with the killer move in the Divine Devil Heaven Suppressing Formation in a few decades,” the Ruler Spark said.

“Okay, then I’ll study it for a few more decades.” Jian Wushuang smiled.

He did not return to the Devil Scorpion Castle. Instead, he began to study it in the void.

The Demon Dragon Lord had become the target of his sword formation trial, so he did not dare to complain.

Time passed day by day. In just 26 years, Jian Wushuang had tried countless times before he finally combined his wave light sword formation with the killer move in the Divine Devil Heaven Suppressing Formation.

In the Void, the Demon Dragon Lord was also covered by the huge golden formation.

Around the formation, three Golden Divine Devil Phantoms had gathered on the three 30,000-meter-tall Heaven Suppression Tablets and burst out with the greatest power.

The suppressive power crazily suppressed the Demon Dragon Lord, so it could only exert 50% of its strength.

“Demon Dragon, take this.”

Jian Wushuang smiled. In an instant, the three Heaven Suppression Tablets burst out with golden light that was as sharp as a blade.

At the same time, Jian Wushuang’s wave light sword formation was activated. The sea of sword essence swept up waves of sword essence.

What was remarkable was that the vast golden light merged with the Sea of sword essence not long after it flew out, in an instant, endless waves of sword intent with golden light covered the sky and earth as they charged toward the Demon Dragon Lord. The power of these waves of sword intent with golden light soared to the sky.

The power of a random wave of sword intent was enough to make an ordinary third-level Ruler’s expression change.

The Demon Dragon Lord held the purple stone staff tightly in his right hand. He also sensed the tyrannical power of the waves of sword intent with golden light around him and immediately attacked. He smashed the staff one after another, but it was only a few collisions, Demon Dragon Lord’s expression changed.

“How is this possible? Although I can only use about 50% of my strength, I’m definitely at the advanced stage of the third level. I’m still much stronger than an ordinary expert of the dark zone. But now, I’m only using a magic weapon, which is a principle-type supreme treasure. How can I just barely defeat one wave of Golden Sword Essence?” Demon Dragon Lord was a little stunned.

Previously, his strength had been absolutely superior to Jian Wushuang’s.

When Jian Wushuang used the sword formation of wave and light, he could easily destroy more than half of the sword formation with a casual strike.

Now, although his strength was suppressed, the sword formation should be shaken by a casual strike.

However, when he used the sword formation, he only managed to destroy the first wave of sword essence, which was coming from the surrounding area.

In other words, the power contained within the golden wave of sword intent was not much weaker than his. It was probably the strongest attack that was comparable to the strongest expert in the dark zone.

For example, the first strike of the thousand killing Emperor Lord was probably as powerful as the first wave of sword intent.

However, the first strike of the thousand killing Emperor Lord was his ultimate move. After the first strike, he had to gather his strength again before he could unleash the second strike.

But now, in the sword formation, endless waves of golden sword essence rushed toward him. Each wave of golden sword essence was comparable to the first move of the thousand-kill emperor. It was too terrifying.

The Demon Dragon Lord had to use his full strength to break the waves of golden sword essence around him. He could withstand one or two waves, or even dozens of waves, but after dozens or hundreds of waves of sword essence.., even Demon Dragon Lord could not withstand it.

“Demon Dragon, use your most powerful move and see if you can break my sword formation,” Jian Wushuang said loudly.

Demon Dragon Lord did not hesitate. He saw a shocking murderous aura sweep up, and black ferocious scales appeared on his face one after another.

He had already revealed part of his original body.

Immediately after, the surface of his body emitted waves of dark light, and the purple stone rod in his hand was swung out one after another.

Hong! Hong! Hong!

Three rod strikes in a row, each of which contained explosive power, directly bombarded the surrounding ocean of sword intent.

Demon Dragon Region Lord’s strongest move, and it was also the strongest move used by a principle true treasure divine weapon. Its power was world-shaking. However, three rod strikes in a row bombarded the ocean of sword intent, and although it caused the entire ocean of sword intent to tremble greatly.., the waves of sword essence collapsed one after another, and a part of the sword formation collapsed, but that was all.

In just a moment, the entire sword formation had completely recovered, and a large number of golden waves of sword essence continued to attack the Demon Dragon Lord.

“This…” The Demon Dragon Lord’s eyes were wide open, and his head was a little dazed.

Seeing this, Jian Wushuang laughed.

“That’s right. The Wave Light Sword Formation and the killing move of the Divine Demon Heaven Suppression Formation are perfectly combined. They complement each other and make my sword formation much more powerful.” Jian Wushuang clenched his hands.

Previously, when he had used the wave light sword formation with all his strength, the power of the sword essence waves could barely match the ordinary attacks of the third level. As for the toughness of the formation…some of the strongest dark zone supreme masters were able to break through his formation head-on.

But now, when combined with the killer move of the Divine Devil Heaven Suppression Formation, golden light covered the surface of the waves of sword intent, and the entire wave light sword formation underwent an earth-shaking transformation.

Now that he had executed his wave light sword formation, the power of each wave of golden sword intent was comparable to the strongest attack of a dark zone supreme master, and it was comparable to the level of the first axe of thousand killing Emperor, in terms of toughness, even Demon Dragon Ruler, one of the ten great kings, could not break it with his strongest killing move using his principle true treasure weapon.

Compared to this, the power had increased by too much.
