“These flames don’t seem to be very strong.”

Jian Wushuang casually waved his sword.

Although it was just a casual move, the power of the universe origin of sword principle and the trace of the universe principle was also extremely powerful, it directly cut open the sky full of surging flames.

However, the black flames did not extinguish immediately. Instead, they burned even more vigorously and continued to surge toward Jian Wushuang.

Jian Wushuang had no choice but to attack again.

Whoosh! Whoosh! Whoosh! Whoosh!

Sword lights slashed out one after another. Although they easily cut through the surging flames, they could not extinguish them.

The flames burned more and more vigorously, and the number of flames increased.

“This formation is a bit difficult to deal with.” Jian Wushuang frowned.

At this moment, Blood Rain Demon Monarch’s figure suddenly appeared in the void around Jian Wushuang.

“It’s useless.” Blood Rain Demon Monarch looked at Jian Wushuang with a wicked smile.

“Blood Sword Master, although your protective ability and life-saving ability are heaven-defying, your own strength is too weak. This formation is carefully arranged by me. Although its offensive power is average, its ability to trap people is very impressive. Even if Thousand-edge Demon Monarch is trapped in this formation, if I don’t let him go, he will have to attack this formation many times with all his strength to break it.

“As for you, you won’t be able to break my formation even if you attack it 10,000 times or 100,000 times.”

Jian Wushuang’s face darkened.

“By the way, didn’t you use a sword skill to trap your enemy?

“In fact, my formation is similar to the sword skill you used before. Your sword skill evolved into a sea of sword essence, which is endless. The black flames in my formation are also endless. The more you attack it, the more it will appear. Unless you can also use an extremely powerful attack to break my formation,” Blood Rain Demon Monarch said with a smile.

Upon hearing his words, Jian Wushuang continued to wave his Divine Sword to attack the black flames. It was just as Blood Rain Demon Monarch had said.

“Huh?”

Jian Wushuang, who was still waving his Divine Sword to cut through the black flames, suddenly widened his eyes.

“Formation? It’s very similar to my Wavelight swordsmanship. Even its conception is similar, and it’s also used to trap enemies?” Jian Wushuang muttered, at this moment, an idea suddenly emerged in his mind. To be exact, it was an idea.

“Formation. What if I also know how to use formation and integrate it into my sword art, such as changing the Wavelight sword art into a Wavelight Sword Formation?” Jian Wushuang could not help thinking.

Formation, and it was a sword art formation.

This sword formation, which relied on the power of the formation, was stronger than his own swordsmanship, no matter what?

And the Earth Guardian swordsmanship. If it could transform the swordsmanship into the Earth Guardian swordsmanship, would its defensive ability be stronger?

This thought flashed through Jian Wushuang’s mind. After thinking about it carefully, he realized that it was possible for him to be tactful.

Since he created the Wavelight sword skill and the Earth Guard sword skill, especially the Earth Guard sword skill, Jian Wushuang had always felt that there was something missing in this sword skill despite its strong defensive ability, it was not truly perfect.

He had always been eager to perfect the Earth Guard sword skill as much as possible and improve it to make it more durable and terrifying.

However, Jian Wushuang had not been able to find a way to improve it, but now, he was trapped in the formation of Blood Rain Demon Monarch. Coupled with the words of Blood Rain Demon Monarch just now, Jian Wushuang suddenly felt enlightened, he found a possibility to improve his swordsmanship.

That was to use the power of the formation to improve his swordsmanship and transform it into a sword formation!

A complete sword formation would definitely be more powerful than a simple swordsmanship.

“Haha, Blood Rain Demon Monarch’s seemingly unintentional words actually helped me a lot. Yes, a sword formation. I can transform my swordsmanship into a sword formation. Moreover, with the formation set up by Blood Rain Demon Monarch, I can also feel many things from this formation. This way, it will be easier to improve it.”

A strange light flashed in Jian Wushuang’s eyes. He immediately sat down cross-legged and began to carefully feel the power of the surrounding formation.

The black flames that filled the sky kept surging toward him. They were endless. Even if they were cut open, they would not be destroyed. Instead, they would become even more vigorous.

These were all things that Jian Wushuang had to carefully experience.

Time began to pass.

Jian Wushuang had found a way to perfect his swordsmanship, so he was not in a hurry to leave the formation. Instead, he stayed in the formation and quietly meditated and experienced it.

In the blink of an eye, 600 years had passed.

During these 600 years, Jian Wushuang stayed in the formation and did not come out.

Meanwhile, Blood Rain Demon Monarch had stayed here for 600 years. Although there were experts passing by, they immediately left in fear when they saw Blood Rain Demon Monarch. They did not dare to get close to him, no one knew what Blood Rain Demon Monarch was doing setting up the array formation here.

Sou! Sou!

Two streams of light rushed over from the distant void at an extremely fast speed. In the blink of an eye, they had arrived at the void where Blood Rain Demon Monarch had set up the array formation.

The streams of light dissipated, and two human figures slowly appeared in this world.

“I’ve finally arrived.”

Thousand-edge Demon Monarch, whose face was like Ice Jade, had a smile on his face.

Beside Thousand-edge Demon Monarch was a tall middle-aged man dressed in a loose robe. This tall middle-aged man’s gaze was cold and his entire body was filled with killing intent.

He was Thousand Kills Emperor Lord.

With thousand kills as his name, there was no doubt that he was a true killing God.

“Thousand-edge, the person you want me to deal with is here?” Thousand Kills Emperor Lord asked.

“Yes, six hundred years ago, he was already trapped here by me. During these six hundred years, I had people use arrays to trap him. After that, I personally went to the 87th dark zone to invite you. Now, I’ve finally invited you over.” Thousand-edge Demon Monarch smiled.

“It’s also because you’ve paid a huge price. Otherwise, I wouldn’t have bothered to accompany you on this trip.” Thousand-edge Demon Monarch had his hands behind his back. At the same time, he gave Thousand-edge Demon Monarch a deep look. “Thousand-edge, I’ve always been very curious. You went through so much trouble to come to the 87th dark zone to invite me, and you’re even willing to pay such a huge price to kill him. What’s so special about him? Or rather, why are you willing to spare no expense to kill him?”

Although Thousand Kills Emperor Lord had been invited here to kill a person for Thousand-edge Demon Monarch, he did not know the reason why Thousand-edge Demon Monarch wanted to kill him, and Thousand-edge Demon Monarch did not tell him the reason.
