When Ye Feng activated the Chaos Hourglass, he was shocked to find that the time around him had actually started to flow backwards.

In just a moment, the scene changed suddenly!

Ye Feng returned to the flowing fairy sail, and time seemed to have flowed back one or two hours ago.

At this time, Ye Feng was still sitting in the flowing fairy sail and heading towards the last ancient killing formation, while the immortal kings and immortal emperors of various sects were probably still ambushing in front of them.

"Since I've given another chance, then... a detour!"

Ye Feng now knows that someone is ambushing ahead, so of course he won’t go straight forward honestly!

Those people must have relied on guessing to know that Ye Feng would go to the next ancient killing formation, but they certainly did not know that Ye Feng would take a detour.

"To prevent the night from getting long and dreaming, it is better to take certain measures."

Ye Feng thought to himself, stood up and walked towards the cabin where the seven monsters in the East were. Soon, he prepared all the remaining fragments of the rules.

Before, Ye Feng only fed two ferocious beasts, the Golden Six-winged Beast, and the Twin Shadow Leopard. In addition to these two monsters, there were five monsters, all of whom had understood the laws of void and the laws of time.

If all the five monsters were fed and the seven monsters were asked to activate the flowing fairy sail at the same time, the speed would definitely be several times faster!

And this requires Ye Feng to consume all the remaining rule fragments.

Of course, for the sake of your own life, these rule fragments should be consumed. Anyway, after returning to the Qing Dynasty, there should be no shortage of natural treasures or rule fragments.

"Everyone is full and go forward at full speed!"

Ye Feng quickly fed all the rules fragments to the other five monsters. Suddenly, Liuguang Xianfan increased his speed several times under the joint force of the seven monsters!

The huge flowing fairy sail quickly moved forward in the void. Not long after, it bypassed the places where the immortal kings and immortal emperors were ambushed, and quickly flew towards the last ancient killing formation.

Not long after, although Ye Feng circled a big circle, he reached the last ancient killing formation, but it was shorter than the original time required.

This killing array is also located in the clouds in the air, condensed into a colorful halo, rising and falling in the clouds.

From this colorful halo, Ye Feng felt a slightly familiar atmosphere.

"Is this...a power similar to the power of the demon dragon?"

Ye Feng was a little surprised. The totem-making magic, the power of the ancient demon dragon and the power of the shining demon dragon that he had practiced before were all unexpectedly obtained.

However, now, the last ancient killing formation in the holy land, which has never been able to leave alive, actually contains similar power of a demon dragon!

No matter what, Ye Feng made up his mind to go in and take a walk.

He put away the flowing fairy sail and knew that he would definitely not be able to stay in place for too long. Therefore, he broke into the colorful halo as quickly as possible, and a strong force of a demon dragon rushed towards him.

His figure disappeared from the clouds in the air and came to a place surrounded by dragon energy.

"Is this, inside that colorful halo?"

Ye Feng looked around and found that the light of various colors in the place was flickering, and each color of light represented the power of a certain demon dragon.

This is the place where all the demon dragons are buried!

"Dragon Killing Formation, Dragon Killing Formation..."

Ye Feng murmured. He felt the colorful halos around him, and could clearly feel the power of the demon dragon in it, the sadness and silence contained in it!

The two words "Long Jue" are revealed from these desolate demon dragon powers.

This ancient killing formation not only devoured countless immortal cultivators who entered it, but also devoured the entire demon dragon clan, becoming an extinction place for the demon dragon clan.

If it were Ye Feng from the past, he would definitely be ecstatic when he came to this place because he had the power of many demon dragons to absorb and comprehend it.

But now Ye Feng is not in the mood to pay attention to the power of these demon dragons.

Because compared with the power of chaos, the power of these demon dragons is really nothing. Instead of spending time to comprehend the power of these demon dragons, it is more realistic to make a breakthrough in the power of chaos.

Moreover, this place is an ancient killing formation!

Ye Feng didn't have so much spare time to comprehend the power of the demon dragon. The most urgent task was to break through this entire killing formation and obtain the chaotic treasure hidden in it.

"It is said that the Demon Dragon Clan is a powerful race in the Immortal World Yu Qingtian. Unexpectedly, they were all buried in this killing formation. It seems that they also wanted to attack the Chaos Treasure in this killing formation, but unfortunately they all died in it..."

Ye Feng moved forward step by step in the colorful halo, feeling the extinction of the demon dragons around him, which made people feel the illusion that they were about to suffocate.

The entire powerful demon dragon clan was buried here, and the power of the demon dragon contained in it was unimaginable. At least, it was not something that the immortal cultivators in Shangqingtian could imagine.

No matter who is from Shangqingtian, or even countless powerful people from Yuqingtian, the immortal world, enter this killing formation and see so many demon dragon powers, they will definitely be extremely moved.

If it were someone else, when I saw so many powerful demon dragons buried in the Dragon Killing Formation, I might feel relieved in my heart. I also had doubts about whether I could pass through this killing formation.

However, Ye Feng was not affected at all.

If he was afraid, he would not have stepped into this killing formation!

Even though no one has been able to pass this killing formation alive since ancient times, Ye Feng has enough confidence in himself and has obtained three Chaos treasures. He must get this one in front of him!

In the upcoming accord against heaven, no one wants to fall under others, and Ye Feng is the same.

He has a gap in his understanding of the power of chaos with other immortal cultivators, and this is definitely not something he can catch up with in a short period of time. His only advantage is to use his talents.

This dragon killing formation is so terrifying. If you can obtain the Chaos Treasure in it, it will obviously increase Ye Feng's strength to a greater level!

When he ignored the power of the demon dragon around him, he found that he had finally arrived at an extremely quiet dark space.

In this dark space, everything returned to peace, and even Ye Feng's heart calmed down. His originally excited and vigilant mood soon became peaceful.

"This space is a killing formation?"

Ye Feng was a little confused. Each of the three ancient killing formations he had experienced before was full of murderous intent, and he wanted to kill the person entering it immediately.

However, in this most dangerous dragon killing formation, there is a tranquility that seems to be eternal!

This situation made Ye Feng more alert. He knew that in such a dangerous place, the more abnormal the situation was, the more hidden the most terrifying danger.

No one has ever walked out of this killing formation alive!

This is the best proof of the danger of this killing formation!
