Legend of Swordsman

18,000 years later, Devil Flame had already refined and absorbed all the special crystals he had obtained, and his divine body had recovered to about 40%.

With about 40% of his divine body, Devil Flame’s realm had recovered to the peak of the fourth-level Ruler, which was infinitely close to the fifth-level. His battle strength was undoubtedly at the fifth-level, even among the fifth-level Rulers, he was extremely strong.

Upon hearing Jian Wushuang’s question, Devil Flame hurriedly said, “Ruler, there are many ways to judge the comprehension of universal principles in the vast universe, but the most convincing one is the Principle Sea.”

“Principle Sea? What is that, the universal Principle Sea?” Jian Wushuang asked in puzzlement.

“No.” Devil Flame shook his head. “Principle Sea is actually a test for the comprehension of universe principles. There are 33 levels of Principle Sea, corresponding to 33 different levels of the comprehension of universe principles.”

!!“The Principle Sea was created by an Ruler force at the core of the universe. It was later widely used in the universe. Most of the top experts in the universe, like those supreme experts, use the Principle Sea as a standard to judge their comprehension of the universe’s principles. The first level of the Principle Sea requires one to Ruler a trace of the universe’s principles to pass it. As for the highest level, the 33rd level, it is said to be the limit of the universe’s principles. It means that one has completely mastered the entire universe’s principles. However, there are only a handful of such supreme experts in the entire universe.”

Upon hearing this, Jian Wushuang was noncommittal.

The universe principle was the supreme principle of the vast universe. Even supreme experts could barely enter it. The 33rd level of the Principle Sea represented the complete Rulery of the universe principle, naturally, it was not something that an ordinary person could pass.

Perhaps even a top-tier supreme expert, or even an invincible supreme expert like Planet Ruler Lingyun, would not be able to pass it.

“My comprehension of the universe’s principles is no longer the same as before. If I go to the Principle Sea, I should be able to pass more than the first level. However, I still have to try how many levels I can pass,” Jian Wushuang thought to himself, then he raised his head and said, “Devil Flame, you just said that the Principle Sea has been widely used in the vast universe. There should be many places where I can pass the Principle Sea, right?”

“Not many places have it.” Devil Flame said seriously, “After all, the universe principle is too high-end. Only supreme experts are qualified to comprehend it. Only a few talented Rulers are qualified to comprehend it. However, because the level is too high, ordinary small and medium-sized Star Fields don’t need the Principle Sea. Therefore, this Principle Sea can only be found in large Star Fields.”

“A large-scale Star Field?” Jian Wushuang was stunned.

A large-scale Star Field had a first-class Star Field, and it definitely had an ultimate level Ruler. Some of the stronger large-scale Star Fields even had supreme-beings.

However, the vast universe mostly had small-scale Star Fields and medium-scale Star Fields. As for large-scale Star Fields, they were only common in the depths of the universe. As for the edge of the universe, although there were some, there were very few.

Jian Wushuang and the others had passed by many Star Fields along the way, but none of them had passed by large Star Fields.

“Husband, if I remember correctly, let’s continue forward. After passing through two small Star Fields, we will arrive at a large Star Field, the Bone Pupil Star Field,” Leng Rushuang said.

Jian Wushuang waved his hand, and a huge star map immediately appeared in the void in front of him.

On the star map, Jian Wushuang soon saw the location of the Bone Pupil Star Field.

“Yes, the Bone Pupil Star Field is the only path we have to take, and it’s not far from where we are now. If we take the universe boat without any delay, we can arrive there in a few hundred years.” Jian Wushuang smiled.

The star map had an introduction about the Bone Pupil Star Field.

The Bone Pupil Star Field was indeed a large Star Field. There were not only level one Star Fields, but also two. There were even more level two and level three Star Fields.

“There are even two level one Star Fields in the Bone Pupil Star Field. There must be a Principle Sea in there. Let’s go to the Bone Pupil Star Field first,” Jian Wushuang said with a smile.

The universe boat flew through the universe void at the fastest speed. After only 300 years, they arrived in the Bone Pupil Star Field.

In the core area of the Bone Pupil Star Field, an island was floating in the void space. The island was quiet.

Normally, since this island was in the core area of the Bone Pupil Star Field, there should be many great beings passing by. However, in fact, this island was almost uninhabited in the Bone Pupil Star Field.

Although the great beings of the Bone Pupil Star Field knew about the existence of this island, they almost did not come here.

On the island, there was an endless sea. At the edge of the sea, a brown-haired old man sat there with his eyes closed. He did not move at all.

The brown-haired old man had been sitting on the island in the same position for hundreds of thousands of years.

He had not moved for hundreds of thousands of years. If people did not know that, they would think that he had died a long time ago.

But suddenly…

“Eh?” The brown-haired elder suddenly opened his eyes, revealing his slightly turbid pupils. “Someone is coming?”

Sure enough, three figures rushed over from not far away and soon arrived at the edge of the ocean.

“Halt,” the brown-haired elder said slowly.

Jian Wushuang and the other two stopped.

“Ruler, the Principle Sea is ahead. Although it looks like an ordinary ocean, in fact, you will find this Principle Sea after you walk along it. It has a different world,” Devil Flame said.

“Okay.” Jian Wushuang nodded slightly and looked at the brown-haired elder who was sitting casually below.

“Whoosh!”

Jian Wushuang and the other two flew down and arrived in front of the brown-haired elder.

“I’m Xue Jian. My wife and one of my guards are beside me. We passed by and heard that there is a Principle Sea here that can determine the level of comprehension of the universe’s principles. We came here to have a look,” Jian Wushuang said with a smile.

“The Principle Sea is not something that just anyone can see. It requires a certain level of comprehension of the universe’s principles. However, among the three of you, the strongest one is only a fourth-level Ruler. I wonder which one of you has comprehended a trace of the universe’s principles?” The brown-haired elder looked over with a light gaze.

“It’s me,” Jian Wushuang said.

“Oh?” The brown-haired elder looked at Jian Wushuang with a hint of surprise in his heart.

He could tell at a glance that Jian Wushuang was only a second-level Ruler.

It was rare for a second-level Ruler to be able to comprehend a trace of the principles of the universe.
