Jian Wushuang had been exploring the dark areas in the Demon Dragon field and challenging the strongest experts in the dark areas. His goal was to perfect his two sword formations as much as possible, over the years, he had gained something, but not much.

The biggest improvement he had made in the two sword formations was in the 9th Dark Zone, under the guidance of Blood Rain Demon Venerable for thirty years.

During those thirty years, his two sword formations could be said to have improved by leaps and bounds.

And now, he had met another expert who was good at formations, and he was publicly acknowledged to be number one in the first level of the Eternal Dark Prison!

This Ruler Spark’s understanding of array formations was definitely higher than Blood Rain Demon Monarch’s, or even much higher.

After all, although Blood Rain Demon Monarch’s attainments in array formations were also high, he was also extremely confident. He believed that his attainments in array formations could barely rank in the top ten of the first level of Eternal Darkness Prison.

But in reality, this sort of ranking was only her own opinion and did not receive the approval of others.

However, it was different for the Ruler Spark. He was recognized by countless cultivators in the first level of Eternal Dark Prison.

His attainments in the Dao of formation must be extremely high.

If Jian Wushuang could subdue such an expert who was good at formation, it would be of great help to him.

“The Demon Dragon Lord is really a good person. It’s one thing for him to come to me, but he actually brought me such a big gift.” Jian Wushuang smiled, feeling extremely happy.

Because of Demon Dragon Lord’s arrival, the fierce battle between Jian Wushuang and White Melody Demon Lord naturally stopped.

Although White Melody Demon Lord did not have much divine power left and it would only take Jian Wushuang a moment to kill him, Jian Wushuang still stopped. White Melody Demon Lord immediately seized the opportunity to escape to the surrounding void.

However, he could not leave immediately because the moment Demon Spirit Lord appeared, the surrounding void was covered by a huge magic formation.

This formation was much more powerful than the one that Blood Rain Demon Monarch had set up in the past.

Moreover, Blood Rain Demon Monarch had set up the formation in the past, so it would take some time to prepare. However, Stone Fire Star Master had set up a more powerful formation with a flip of his hand.

Jian Wushuang, Emperor Sha, and White Melody Demon Lord could not escape from the formation.

“I can feel that the formation is very strong. Even if I use my strongest skills, I’m afraid I Won’t be able to break it,” Emperor Sha said in a low voice.

“To be able to set up such a powerful formation with a flip of his hand, the attainments of Stone Fire Star Master in the Dao of formation are indeed impressive.” Jian Wushuang’s eyes shone with brilliance.

The more skilled he was in the Dao of formations, the happier he felt.

Whoosh!

In a flash, White Melody Demon Lord arrived in the void in front of Demon Dragon Lord and the others.

“Lord, you must be here for Blood Sword Master. It has nothing to do with me. Please let me go. White Melody will remember your kindness. No matter what your orders are, I will do my best.” White Melody Demon Lord was very respectful, his attitude was extremely low.

His divine power had been greatly damaged, and he didn’t want to stay any longer.

And from his point of view, he was the strongest expert in the dark zone. In terms of strength, he was not like the Dark Fire Ruler, Demon King Myriad Bones, or Marquis Suxin. And now, his attitude was so low…he had even promised to work for Demon Dragon Lord in the future. Demon Dragon Lord should have let him go.

But in reality…

Demon Dragon Region Lord merely shot a cold glance at White Melody before waving his hand.

Boom!

A majestic might suddenly swept out, transforming into a bolt of purple divine lightning. The purple divine lightning contained a terrifying destructive power as it struck White Melody’s body.

White Melody widened his eyes as a trace of hatred and anger flashed in his eyes. However, his aura began to dissipate.

With a wave of his hand, White Melody died.

“Hmph. A piece of trash wants to work for me? How laughable.” Demon Dragon Region Lord was disdainful.

Ruler Red One, Demon King Myriad Bones, and the others behind him weren’t surprised at all.

Demon Dragon Region Lord was one of the ten great monarchs. He was the Region Lord of the devildragon realm, and he was a lofty figure. How could it be so easy for him to work for him?

The reason why they were able to work for Demon Dragon Lord was because of some special factors. Otherwise, Demon Dragon Lord would not have bothered to look at them, except for Red One.

Jian Wushuang and Emperor Sha were surprised to see this.

“He is the strongest expert in the dark zone. Although I have used up more than half of his divine power, Demon Dragon Lord did not use his full strength. He simply killed him without even taking out his supreme treasure weapon.” Jian Wushuang was secretly amazed.

At the same time, he understood that Demon Dragon Lord’s strength was stronger than he had imagined.

Previously, he had heard that the most powerful attacks of the thousand kill Emperor Lord and Emperor Sha Ruler were comparable to the power of ordinary kings. But now, it seemed that they were comparable, however, they were only comparable to the power of a casual attack from the ten great kings. If the ten great kings were slightly more serious and took out their supreme treasures and divine weapons, the power they could unleash…would definitely be much stronger than the most powerful attacks of Thousand Kills Emperor Lord and Emperor Sha.

After killing White Melody Demon Lord, Demon Dragon Lord’s expression did not change at all. He looked at Jian Wushuang again with his cold eyes, however, there was a hint of unconcealable fanaticism in the depths of his eyes.

“Blood Sword Master, I’ll give you a chance. Hand over your two principle supreme treasures and submit to me. I can promise not to kill you,” Demon Dragon Lord growled.

“Oh, you want me to submit?” Jian Wushuang smiled faintly. He was not surprised.

Just like when he met Demon Emperor ancient night, Demon Emperor ancient night wanted to subdue him at first. He was extremely excited because demon emperor ancient night had left Eternal Dark Prison and returned to the universe, moreover, he had a master behind him. That was why he wanted a super genius like him.

However, Demon Dragon Lord was still in the Eternal Dark Prison, where geniuses were not worth anything. He probably wanted to subdue Jian Wushuang to save some trouble, he did not really care about Jian Wushuang’s talent.

“Demon Dragon Lord, you’d better make a move. Let me see how strong you are as one of the ten kings.” Jian Wushuang beckoned Demon Dragon Lord with a provocative look.
