Just when the wind elements in Li Feng's body surged towards his Dantian, the endless strong wind in the passage disappeared and was replaced by endless heat.

"What's going on?"

"Just now it was wind, now it's fire?"

Li Feng was a little dumbfounded when he felt this situation.

boom!

At this moment, those wind elements finally rushed to Li Feng's dantian.

In an instant, Li Feng felt as if his Dantian was about to explode.

"Is this Dantian really unbreakable?"

"If the Dantian is broken, can the people from the Heavenly Medicine Sect treat it?"

"Those two people from the Heavenly Medicine Sect are so unbelievable. It would be great if we could tie them to our side."

Random thoughts flashed through his mind, and Li Feng quickly went to check his Dantian.

Because at this moment, apart from the exploding feeling, there were no other changes in Dantian.

"Blue True Essence Lake?"

"Is this the Wind Element True Essence Lake?"

"Really Wind Core?"

"Is there really a wind core formed in the dantian?"

Li Feng was shocked.

Starting from the non-attributed True Essence Lake, there are the metal system, wood system, water system, fire system, earth system... and then to the thunder and lightning system, death system and now the wind system.

Starting from the formation of the magic core, water core, ice core, thunder core, cinder core...and now the wind core.

What the hell is going on?

Is this really the inevitable process for him to break through to the Martial Emperor Realm?

But I don't know what happened.

But those wind elements entered his body and formed the attribute true energy lake and wind core. At least he was safe.

This can be considered a good thing.

"Just now it was the wind element, and next is the fire element. Could it be that the fire elements here can allow him to form a fire core?"

"But if that's really the case, it's not a bad idea."

Li Feng has now looked away.

As corresponding nuclei formed in each true essence lake, he knew that this was inevitable.

So, in this case, let these nuclei form faster.

Only after they are formed will he know what these nuclei do after they are formed.

Thinking of this, Li Feng took a few Yunxin Pills and continued walking forward.

Less than a quarter of an hour later, the passage that appeared in front of Li Feng was ablaze with fire.

"fire."

"I didn't expect it to happen in this way."

"It seems that it will be done as soon as possible."

"I just don't know what kind of fire this fire is."

Li Feng thought of his own Youziye Fire.

He is not only a cultivator of the fire system, but also possesses the mysterious purple fire.

Therefore, at this moment, he was thinking whether to let You Ziye fire absorb the fire here, or to use the fire essence to let these fire elements enter the body, thus forming a fire core in the fire essence lake just like before

?

If it were in the past, he would definitely choose to use Youziye Fire.

After all, the power of Youziye Fire can be enhanced after swallowing the flames, which is also good for him.

But at this moment, because of the various cores in the True Essence Lake in his Dantian, Li Feng felt that You Ziye Fire should not be used.

At that moment, Li Feng walked step by step into the flames.

The flames were filled with terrifying fire elements.

At this moment, Li Feng seemed to be barbecued in a blazing fire.

Hot, boiling hot.

This is the sea of ​​fire.

This is Li Feng's current experience.

At first, Li Feng didn't think much of it.

But as he moved forward, Li Feng began to be unable to bear it anymore.

At this moment, Li Feng finally knew what roasting on the fire was like.

But Li Feng had no choice but to pass through this passage as quickly as possible.

But walking in fire and walking in wind are not the same thing at all.

At this time, Li Feng's speed slowed down to the extreme.

The hot fire element seemed to be able to scorch him.

At this moment, Li Feng felt that he was about to become black coal.

In fact, if things continue like this, Li Feng doubts whether he will be able to practice with Hu Yuanyuan and others in the future.

Unfortunately, Li Feng now has no choice but to use his true energy to protect himself.

Time flies, and a day passes in the blink of an eye.

At this time, Li Feng's whole body was red.

All the meat on his body seemed to be roasted.

The terrifying heat made it difficult for Li Feng to breathe.

Under the fire element, all the hair on Li Feng's body was burned away.

"If I can't hold on any longer..."

Although in this sea of ​​fire, one can still practice the Xuantian Body Refining Technique.

But he had just made a breakthrough before, and in this sea of ​​fire, even if he practiced the Xuantian Body Refining Technique, there was no sign of a breakthrough.

Even at the critical moment, Li Feng used the water element and ice element, but he could not solve the fire element in the sea of ​​fire.

At this moment, Li Feng had reached his extreme.

The fire element in the body has also accumulated to a certain extent.

Li Feng just waited for these fire elements to enter his Dantian and form a fire core.

However, for some unknown reason, these fire elements did not flock to the red fire elemental lake like the wind elements did before.

And the energy that guided the wind elements before did not appear at this time.

"Um?"

At this moment, Li Feng passed through the flames and saw a stone platform in front of him.

"Are you going to the end?"

"Then hold on."

Li Feng's eyes were firm.

He didn't know what was on the stone platform and whether there was the token.

But he felt that as long as he got to the other side of the stone platform, his mission this time could be completed.

At least it can solve the flame problem.

After all, he could hardly hold on anymore.

What's more, now he has no choice.

However, at this time, Li Feng discovered how difficult it was to cross this distance.

With every step he took, Li Feng felt helpless.

"It seems like this is the only way."

Li Feng's eyes flashed.

The next moment, purple flames appeared from his body.
To be continued...
