Devil Flame was an ultimate Ruler. In terms of strength, it was much stronger than the Lord of the Devil Cloud Star. Even though it was only in the soul body state, its soul had already completely recovered, moreover, its gold-swallowing divine body had already begun to be reconstructed.

As long as it was reconstructed to a certain level, Devil Flame’s soul body would be able to perfectly fit with the gold-swallowing divine body, thus possessing a certain combat strength when he was alive.

According to Devil Flame’s own words, as long as the gold-swallowing divine body could recover ten to twenty percent, he would be able to use this divine body to barely display the combat strength of a fourth-level Ruler. Moreover, with his experience when he was alive, he already had some secret techniques, Devil Cloud Master, who had just reached the fourth-level Ruler realm, was definitely no match for him.

“Whether it’s breaking through to the Ruler realm or subduing a large number of experts in the Eternal Dark Prison, I can barely fight against Devil Cloud Master. However, it’s still not enough to completely remove the threat from Devil Cloud Star. I can only restore Devil Flame’s strength to a certain extent. It doesn’t need much. With his experience and skills, he can kill Devil Cloud Master and then completely solve the crisis of Devil Cloud Star,” Jian Wushuang thought.

It seemed to Jian Wushuang that it was feasible to use the Devil Flame to kill Star Master Devil Cloud.

Although he could not completely trust the Devil Flame, he was at least in control of its life and death. With this method, the Devil Flame would not dare to resist him.

In order to recover the gold-swallowing divine body of the Devil Flame, he needed a large number of special gems, and the higher the level, the better.

“Blood Rain, take out all the special gems in your hand,” Jian Wushuang instructed.

“Yes.” Blood Rain Demon Monarch nodded and immediately counted the special gems in his hand before handing them over to Jian Wushuang.

“Devil Flame, I can devour the Green Gold World Stone, Blood Rain, Thousand Kills, and all the special gems in my hand. In the following days, I will try my best to find more special gems for you. What you need to do is to improve your gold-devouring divine body as much as possible,” Jian Wushuang said.

“Understood. Thank you, Master.” Devil Flame was pleasantly surprised.

After speaking to Devil Flame, Jian Wushuang looked at the two slaves in front of him again.

“Blood Rain, your attainments in the dao of formation are very high, and I just happen to be developing my sword skill into a sword formation. Although I have gained some understanding during the past 600 years in your formation and formed the most basic sword formation, the sword formation is too simple. Next, I need you and Thousand-edge to help me perfect my sword formation as much as possible,” Jian Wushuang said.

Blood Rain Demon Monarch and Thousand Kills Emperor Lord looked at each other and laughed.

“Master, don’t worry. Perhaps I can’t guarantee anything else, but in terms of array formations, there are no more than ten people in the first level of Eternal Darkness Prison who are stronger than me. Since master wants to transform his sword techniques into a complete sword array, I can naturally help you.” Blood Rain Demon Monarch said with a smile.

“I don’t have a good understanding of the dao of formation, but my offensive power is not weak. Master, if you want to test your sword formation, you can look for me,” Thousand-edge Demon Monarch said.

“Okay.” Jian Wushuang also smiled. “Blood Rain, I’ll show you the two sword formations that I’ve improved over the years. Look carefully and help me find as many principles as possible.”

Jian Wushuang immediately walked out of the cave mansion with his two slaves. In the void outside, Jian Wushuang directly began to show his two sword formations.

First, of course, was the Wavelight sword formation.

Hum hum hum hum. A sea of sword essence swept out, filling the surroundings with an endless concept. The entire sea of sword essence was covered by a layer of formation.

Once the Wavelight sword formation was activated, Blood Rain Demon Monarch, who was at the center of the sword formation, saw through the many principles in the Wavelight sword formation with just a glance.

“Master, although I haven’t really experienced your sword formation, I’ve already seen 13 principles with just my eyes. Four of them don’t have much impact, but there are still nine areas that clearly have a lot of room for improvement,” Blood Rain Demon Monarch said.

“Oh?” Jian Wushuang’s eyes lit up.

His sword formation had just been used, and Blood Rain Demon Monarch had not really experienced its power yet, but he had seen so many principles with just one look?

And there were nine that had a lot of room for improvement?

“Sure enough, Blood Rain Demon Monarch, who is good at formations, can help me improve this sword formation.” Jian Wushuang smiled. “Blood Rain, you haven’t felt the power of the sword formation. Now, I will activate the Sword Formation for you. Feel it carefully.”

Jian Wushuang laughed and immediately, the overwhelming sea of sword essence rushed toward Blood Rain Demon Monarch.

Blood Rain Demon Monarch was caught in the attack of the sea of sword essence. He blocked the incoming sword essence at will, and at the same time, he found the principles in the formation.

After finding the principles, he would further improve the sword formation according to Blood Rain Demon Monarch’s suggestion. Naturally, Jian Wushuang’s sword formation would be significantly improved.

Thirty years passed in the blink of an eye.

During these thirty years, Jian Wushuang did not travel to other places in the ninth dark zone. Instead, he stayed in the same place. Blood Rain Demon Monarch and Thousand-edge Demon Monarch stayed by his side.

During the past 30 years, Jian Wushuang had been improving his two sword formations with the help of Blood Rain Demon Monarch and Thousand-edge Demon Monarch.

It had to be said that the improvement of the sword formation with the help of Blood Rain Demon Monarch was countless times faster than Jian Wushuang comprehending and improving the formation set by Blood Rain Demon Monarch alone.

Previously, he had been comprehending the formation set by Blood Rain Demon Monarch alone for 600 years. In Jian Wushuang’s opinion, it was still not as good as the improvement of one year with the help of Blood Rain Demon Monarch.

After 30 years, the two sword formations of Jian Wushuang were worlds apart compared to 30 years.

In the vast void, Jian Wushuang and Blood Rain Demon Monarch stood side by side. In the void in front of them, Thousand-edge Demon Monarch was standing there, bearing the impact of the surrounding sea of sword essence at the same time.

They were both Sea of sword essence, but now that the sea of sword essence was supported by the formation, its power was greatly different.

Each wave of sword intent was enough to make an ordinary third-level Ruler go all out. The impact force contained in the waves of sword intent…was enough to easily crush the divine body of an ordinary second-level Ruler.

In terms of power alone, the Sea of sword intent was dozens of times stronger than before.

Although the Thousand Kills Emperor Lord was powerful, he had to deal with the impact of the waves around him seriously when he was trapped in the Sea of sword intent.
