Yun Feng just felt a little sorry for Wu Wudi's talent. He quickly calmed down and left the cave where the mural was located, heading towards the deepest part of Lingyun Cave.

Soon, Yun Feng reached the deepest part of Lingyun Cave.

There is nothing else in the depths of Lingyun Cave, only a thick stone throne.

On the throne, a pair of skeletons are holding a giant sword, sitting with their heads bowed. Behind them is a stone tablet with the four characters "Tomb of the Yellow Emperor" written on it.

Yun Feng also noticed that next to the skeleton, a piece of alien bone was randomly placed on the throne, just like debris that could be seen everywhere.

"Senior Huangdi, this junior took the dragon vein today. If you offend me, please don't blame me."

Yun Feng bowed to the skeleton and said solemnly.

For Yun Feng, even though the Xuanyuan Huangdi of Fengyun World was not the legendary Xuanyuan Huangdi of the world before he traveled through time, he still had a sense of awe in his heart.

This has nothing to do with strength, it's just Yun Feng's personal philosophy.

As soon as Yun Feng finished speaking, Xuanyuan Huangdi's skeleton collapsed instantly, and the giant sword in the skeleton's hand fell towards Yun Feng as if it had spirituality.

Yun Feng subconsciously reached out and grasped the hilt of the sword.

A faint consciousness came out from the giant sword and turned into a deep voice in Yun Feng's mind——

"Dragon Vein is formed by the condensed righteous energy of the nine states. I hope you can use it well and don't fall into evil ways!"

As the sound rang out, the hilt of the sword held by Yun Feng instantly shattered, and the giant sword turned into countless fine dust and completely dissipated.

"Is it a backup plan left by Senior Huang Di?"

Yun Feng looked at the bones scattered on the ground and the giant sword that had completely dissipated. He sighed lightly and blasted a blast of energy to the side.

The ground shook and a large crater appeared instantly.

Yun Feng's true energy surged, gathering the scattered bones, placing them into the large pit, and covering them with a thin layer of soil.

After doing all this, Yun Feng walked towards the alien bone placed randomly on the throne.

[I found the top extraordinary item Dragon Vein, should I absorb it?]

As soon as Yun Feng's palm grasped the alien bone on the throne, the system prompt sounded in Yun Feng's ears.

"absorb!"

Yun Feng didn't hesitate at all and immediately ordered in his heart.

[Successfully absorbed top extraordinary items, heavenly energy +30000!]

[Successfully absorbed top extraordinary items and obtained a large amount of the source of heavenly law in the world of wind and cloud! 】

[Congratulations to the host, because the host successfully obtained half of the Heavenly Dao origin of Fengyun World, and obtained the special item Tiandao Covenant (Fengyun)! 】

Hearing the system prompt ringing in his ears, Yun Feng's eyes suddenly brightened.

Even though he knew that the dragon vein could provide a lot of heavenly energy, he didn't expect that the dragon vein could provide a full 30,000 heavenly energy!

You must know that even the top magic weapons in the Zhuxian world, the Xuanhuojian, the blood-devouring beads and the soul-destroying rod, did not provide him with 30,000 heavenly energy!

It can be said that the dragon vein of Fengyun World is the one that provides him with the most heavenly energy among all the extraordinary items Yun Feng has obtained so far!

Not to mention that in addition to the energy of Heavenly Dao, the dragon veins of Fengyun World directly provided him with half of the origin of Heavenly Dao in Fengyun World!

"I don't know what the Covenant of Heaven is..."

Yun Feng quickly calmed down and turned his attention to that special item.

When he was in Zhuxian World, because he obtained a quarter of the origin of Heavenly Dao in Zhuxian World, he obtained the Heavenly Dao Order of Zhuxian World, which could mobilize the laws of Heavenly Dao within a hundred miles radius, directly making him innately invincible in Zhuxian World.

land.

But this Covenant of Heavenly Dao was something he got only after he obtained half of the origin of Heavenly Dao in Fengyun World. It must have an even more amazing effect than the Heavenly Dao Order!

Thinking of this, Yun Feng made a thought and directly took out the special item Tiandao Covenant he had just obtained from the system space.

The Covenant of Heaven's Law and the Order of Heaven's Law are somewhat similar. They are both tokens that are neither gold nor jade and look dull.

The difference is that there is no text on the Tiandao Order, but a large word "covenant" is engraved on the front of the Tiandao Covenant, and there are a large number of mysterious and clumsy words on the back.

Even with Yun Feng's knowledge, he couldn't identify what the words on the back of the Heavenly Covenant meant.

[Tiandao Covenant (Wind and Cloud)]: A token of Heavenly Dao in Fengyun World. Those who hold the Heavenly Dao Covenant are not bound by the laws of Heaven. They have the qualification to change the laws of Heaven once and can change the laws of Heaven to a certain extent.

Seeing the introduction of the Tiandao Covenant, Yun Feng's breathing became a lot faster.

With the qualification to change the laws of heaven, you can change the laws of heaven to a certain extent!

This alone is enough to elevate the value of the Heavenly Covenant to an inestimable level!

Even if this opportunity only comes once!

Because the laws of heaven are different in each world, such as the Douluo world and the Zhuxian world, or the Fengyun world and the Zhuxian world.

It's just that the difference in the laws of heaven between the Fengyun world and the Zhuxian world is not as big as the difference between the laws of heaven in the Douluo world and the Zhuxian world!

Once creatures from different worlds enter other worlds, they will be affected by the laws of heaven. At least their strength will be damaged, or at worst, their strength will be completely suppressed and they will become ordinary people!

But the existence of the Heavenly Covenant can change this situation to a certain extent!

For Yun Feng, the biggest role of the Covenant of Heaven is to make the laws of Heaven in Fengyun World closer to the laws of Heaven in Zhuxian World!

In this way, when the creatures from the Zhuxian world enter the Fengyun world in the future, they will be less affected by the laws of heaven.

Even just like the creatures from the human world in the Zhuxian world entering the other five realms of the Zhuxian world, they will not be affected at all!

Not only that, the laws of heaven in Fengyun World are close to Zhuxian World, which will also benefit the creatures in Fengyun World.

For example, in the past, no matter how talented a genius like Wu Wudi was, he could only stop at being a great martial arts master.

But after the changes in the laws of heaven, it is possible to break through the golden elixir of martial arts!

And once there is a strong man of martial arts and golden elixir level in Fengyun World, the laws of heaven in Fengyun World will be further complemented, and the entire Fengyun World will also benefit from this!

"call……"

Slowly exhaling a breath of turbid air, Yun Feng gradually calmed down, and then with a thought, he directly activated the Heavenly Covenant.

A series of mysterious auras emanated from the Heavenly Covenant, and Yun Feng entered a strange state. There were countless Heavenly Laws manifesting around him, and they continued to change to a certain extent with his thoughts.

If anyone enters the deepest part of Lingyun Cave now, they will find that the entire depth of Lingyun Cave has been shrouded in mysterious power, and it seems that it may disappear at any time.
