Right now, Long Chen saw that the three Dragon Emperor s had already been completely immersed in the battle. Countless b.l.o.o.d.y threads extended from their bodies and converged together with the Dragon Sword Diagram, which belonged to the three Dragon Emperor s. It was a wave of energy that could easily destroy heaven and earth, or even the entire Everlasting Dragon City!

Right now, they were all trying their best to channel the reincarnation power of the nine palaces into their Primordial Dragon Swords and instigate an even more powerful divine power in them. They already had the complete World Tree, and Heart of Rules was s.h.i.+ning brightly, there were even nearly a hundred million Divine Palaces on it. There were countless creatures within.

This was the huge difference between Dragon Emperor s and b.l.o.o.d.y Skylight Emperor and the rest.

Long Chen felt like he was in a sea of energy. In front of the three Dragon Emperor s, he was as minuscule as a small boat, moving forward in this sea of storm. If it wasn't for the three Dragon Emperor s not wanting to harm him, this small boat would probably have been torn apart.

BOOM!

When the sharp cry was released from the sword tip, Long Chen knew that the sword tip had already been completely activated! This … …

"Attack!" "Dragon Sword!"

The three Dragon Emperor s shouted at the same time.

In that instant, the Primordial Dragon Sword trembled violently. Then, it began to move in that instant, and under the joint control of the three Dragon Emperor s, the Primordial Dragon Sword burst out with unparalleled speed, and in that instant, it pa.s.sed through countless barriers, appearing in the air above Slaughter Dragon City.

However, in that split-second, not even a powerhouse at the level of Bloodl.u.s.t could react. The tip of the Dragon Sword disappeared before their eyes. Countless people stared blankly at the s.h.i.+ning sky, some even thinking that they had seen wrongly.

"This is?"

For a time, everyone started to argue.

Bloodl.u.s.t ordered from above.

b.l.o.o.d.y Blaze's position in the Slaughter Dragon City was similar to the Azure Fire Emperor's position in the Everlasting Dragon City. She was slightly higher than a normal Overlord.

Hearing his words, everyone was relieved. However, they were still discussing in private about what had just happened in the air above the Dragon Slayer City.

In actuality, the same thing happened in Five Dragon Cities just now.

During this process, Long Chen discovered something strange.

He had already traveled several tens of thousands of kilometers by now, but he was still connected to it, as if it was one ent.i.ty. could even see through the Dragon Sword and see everything around it, which was something that not even fifteen Dragon Emperor were able to accomplish. The fifteen Dragon Emperor only needed to tell the Dragon Sword who it needed to kill, and the Dragon Sword would find its own target to make a move. The only thing the fifteen Dragon Emperor could do was to supply them with energy.

However, Long Chen was actually able to see everything that the Primordial Dragon Sword saw.

Because the sword tip was extremely fast, Long Chen could not see it clearly. However, he could confirm that the sword tip was heading towards the south at a terrifying speed. He estimated that it would not even take an hour to reach the central core.

He told his discovery to the three Dragon Emperor s.

When they found out about this news, the three Dragon Emperor s were extremely shocked.

"Just nice, we can know the result and learn more about the Black Emperor's secrets."

It was only at this time that he finally slowed down his speed, allowing Long Chen to better observe his surroundings. In the distance, four terrifying rays of light were converging towards the same direction, and the tip of the Dragon Sword was also converging towards that same point!

"It's time to combine!"

It was obviously a part of the other four Dragon Cities' Dragon Swords.

It seemed very far away, but in the blink of an eye.

It had to be said that this was an extremely spectacular combination.

The blood colored sword blade first reached above, followed by two parts of the sword blade coming under the sword tip, fusing together, and then the fifteen colors of the sword hilt, coming from the Life Dragon City. In the end, at the core of the Dragon City, the sword soul of the Dragon Sword had merged with it.

Only when the five parts truly merged into one did the Sublime Dragon Sword truly appear!

All colors blended together.

The color turned into nothingness, and the shape also changed. In the end, it turned into a dragon sword, completely black, ancient and deep, the blade covered in dragon scales, the hilt a lifelike dragon's head, the tip of the sword the sharpest dragon claw.

BOOM!

When a true Limitless Dao weapon appears, its power will definitely be ten times more powerful than any other part of the Primordial Dragon Sword!

Even the pressure was at least ten times stronger.

Long Chen was still connected to the Primordial Dragon Sword, but even if the other party didn't come to suppress him, he still felt extremely uncomfortable.

The Dragon Sword was not controlled by the fifteen Dragon Emperor s.

When it was formed, a roar sounded out and it seemed to resonate throughout the entire Dragon G.o.d Domain. From this, it could be seen how loud this roar was. At least with a sound, the mountain peaks with a radius of over 10,000 miles were flattened by the violent winds!

The power of anger!

There were fifteen Dragon Emperor s who were furious, as well as Long Chen.

At the same time, it was also a power that was provoked with respect. The attack of the Dragon King's Sword this time was for dignity!

The black dragon's scales were filled with killing intent and in that instant, its speed had increased by countless times. From now on, it would search for the Black h.e.l.l King with the support of the fifteen Dragon Emperor s!

Long Chen looked ahead. The three Dragon Emperor s had already closed their eyes, and were focused on channeling energy into them, activating the Primordial Dragon Sword. The other twelve Dragon Emperor s were doing the same as well, using all of their skills.

Even if it were to search the entire Dragon G.o.d Domain, it would not take too much time. Especially since the Black Emperor was so powerful, it would not be difficult for the Dragon King's Ancestral Sword to find him.

At the moment, the Great Zu Dragon Sword was like a living divine dragon, swiftly searching, stopping occasionally to search slowly. Initially, it would search in the central region, then it would go to the southern region, and it would even fly over the Everlasting Dragon City.

"What a huge consumption."

The Dragon Emperor couldn't help but sigh. He had not found the Emperor of Black Underworld yet, but just searching had consumed the vast power of the Dragon Emperor s. Fortunately, the Dragon Emperor s were behind their cultivation, otherwise, they would have been sucked into smithereens sooner or later!

From the southern region to the western region.

However, the Black King was still not here.

A few hours later, the Dragon Sword began flying towards the northern region, where the slaying of the Dragon City Lord was located. When they reached there, everyone's hearts could not help but rise. It was Long Chen who told them that they were already in the northern region.

This was the most promising area.

This was because Long Chen was here, and was also where the Black King had appeared last. Thus, the chances of him still hiding here was extremely high.

Even the Great Ancestor Dragon Sword seemed to have sensed Long Chen's thoughts, as its speed of searching became slower and it searched even more seriously, flying above one Shencheng after another.

He could roughly feel the power of the Primordial Dragon Sword, which was a peak level that he had never seen before. It could be said that none of the Dragon Emperor could block the Primordial Dragon Sword, and they might even be instantly killed.

If he could find Black h.e.l.l King, Long Chen didn't believe that he could escape.

After all, in terms of speed, all the Dragon Swords were more than ten times faster than the fifteen Dragon Emperor s, or at least fifteen times faster.

"Emperor of Black Underworld, Chen Ting!"

Long Chen patiently followed the Primordial Dragon Sword.

He even had a premonition that the Dragon Sword had found some clues. Its speed began to slow down, and it was extremely slow as it dived towards a certain direction.

Long Chen reminded her.

If they could control the Dragon Sword, they would definitely have it search the north first. After all, it was most likely that the Black h.e.l.l King was here.

But there was no other way!

He could only do it in one go!

The Great Zu Dragon Sword flew across the Dragon Slaying City and headed towards the north. If they left the continent, they would reach the stars, and if they went towards the northwest, they would reach the chaotic star field.

The position of the Black Demon Emperor was still within the Immortal G.o.d Region.

The speed of the Primordial Dragon Sword became even slower. Long Chen had a premonition that the Black h.e.l.l King was definitely in the vicinity of this stretch of black mountains and he could even smell the Black h.e.l.l Beast's scent.

"I've found it. Prepare to attack!"

Long Chen whispered to everyone.

As the Dragon Sword pa.s.sed through several mountain peaks, a black lake appeared below it. Ripples appeared in the lake as black tentacles swayed in the air …
