I saw that the moment this mysterious energy entered Yun Feng's mind space, it suddenly turned into a trace of gray energy, floating quietly in Yun Feng's mind space.

"It turns out that this gray energy was caused by the oath I swore..." Yun Feng suddenly realized.

This gray energy was not the first gray energy in his mind.

When he left Fenglin Universe, he suddenly found a trace of gray energy in his mind space.

He said that there was a trace of gray energy in his mind.

At that time, he thought that he was about to successfully cultivate the 108 Godheads, and a special change occurred in his mind.

The mind space is a very mysterious space, and no one can tell what kind of changes there will be.

Yun Feng is not sure either.

Seeing that this gray energy did not affect his training and strength, Yun Feng ignored it.

Now, Yun Feng knew that these two strands of gray energy were formed from the two oaths he made.

The oath is not just an ordinary oath.

It is estimated that the path of the Martial God must be used as a guarantee to generate such gray energy.

Yun Feng secretly said.

He had made similar guarantees before, but no such gray energy was produced.

And just now, he also made an alliance oath using the Way of the God of War in Fenglin Universe, and as a result, there was a trace of gray energy in his mind space.

This made Yun Feng guess so.

"Huh?" At this moment, Yun Feng's eyes suddenly widened.

It turned out that at this moment, the power of the God of War realm that he had been using to feel these two strands of gray energy actually felt like it was refining these two strands of gray energy.

Can these two strands of gray energy be refined?

Yun Feng was a little shocked.

Yun Feng vaguely felt that these two gray energies could not be refined in the ordinary Martial God realm.

Because when Yun Feng saw the first trace of gray energy for the first time, he had already tried it with his Martial God Domain, and he couldn't refine it at all.

Now... there is actually a feeling that it can be refined... His Martial God Realm has even refined these two gray energies a little bit...

Why wasn't Yun Feng shocked by this?

If these two strands of gray energy are used to restrain the oath he swore, then if these two strands of gray energy are refined by him, doesn't it mean that he can no longer abide by the oath he swore?

Thinking like this, Yun Feng felt a little weird again.

If that's the case, can he freely use the path of the God of War to swear oaths in the future?

This, it would be a good idea to use it to trick people one day...

Yun Feng secretly said.

It should be due to the power of the laws of the lower realm.

Soon, Yun Feng found out the reason why these two gray energies could be refined. The problem lay in the power of the new laws of the lower realm.

It seemed that the power of these new laws of the lower realm had some changes that he could not see.

Yun Feng secretly said.

Huh-huh-huh-

The speed of refining these two strands of gray energy was beyond Yun Feng's expectations.

Yun Feng just thought for a moment, and these two traces of gray energy were refined by Yun Feng.

"Supreme Rosen, do you want to go to Li Zhen Universe with me now?" Yun Feng shook his head slightly in his heart, then looked at Rosen and asked.

"Of course, Li Zhen Universe and Potian Universe have formed an alliance. Li Zhen Universe is in danger now, and I, Rosen, naturally have to do it!" Rosen immediately said "righteously".

Seeing Rosen like this, Yun Feng wanted to laugh in his heart.

He has detected the thoughts in Rosen's mind, but he probably doesn't know yet.

However, Yun Feng didn't expose it either.

"Okay, let's set off now!" Yun Feng smiled and nodded.

"boom--"

As he spoke, Yun Feng turned around, used his mind to draw the Emperor's Sword, and stabbed into the space in front of him.

Before Li Tian fell asleep, he had already handed the Emperor's Sword to Yun Feng.
