Rumble…

At this moment, some kind of restriction in the City of Nothingness seemed to be triggered, and an unrivaled energy burst out, as if it could destroy everything. Endless murderous intent emanated from the City of Nothingness.

The energy storm that swept out caused the heaven and earth to shake. It was as terrifying as the broken sky, and the violent energy tore the heaven and earth apart. Wherever it passed, the void shattered, and black space cracks appeared.

Looking from a distance, there is a black and white energy group above the void battlefield.

Because the distance was too far, it was not clear what the energy group was, but to Mo Renfei and the others, the energy group that appeared in the sky above the City of Nothingness was strange.

Around this energy group, there are countless lightnings whistling and circling.

All of this means that the entire City of Nothingness has become a realm of extremity and death.

At this moment, everyone outside the City of Nothingness looked at this scene in shock.

The terrifying wave of power that surged out from the city of nothingness, which was as devastating as the heaven and earth, made even the people who retreated far away feel a sense of powerlessness.

"This time, Li Feng must be dead, right?" Mo Renfei's voice was a little hoarse.

"I don't know, but I think he may not be dead. Otherwise, the people around Li Feng would not be so quiet." Tang Qingjian looked at Tian Yuzhou as he spoke.

If something happens to Li Feng, the people in Tianyu Zhou will be most anxious, but now it seems that Tianyu Zhou is still very quiet.

"If Li Feng and the others are all dead, then..." Mo Renfei looked at Tianyu Zhou with a greedy look in his eyes.

On the other side, in the Tianyu boat, Huangfu Wei and others looked at the city of nothingness through light and shadow.

The huge defensive power of the Tianyu Boat withstood the vast energy impact from the City of Nothingness, but at this time Huangfuwei and the others' minds were not on the Tianyu Boat, but in the City of Nothingness.

Xiao Hei was kept by Li Feng, so if Xiao Hei was fine, Li Feng would be fine, but this could not stop them from worrying.

But at this moment, Huangfuwei and the others can only worry, because they can't interfere in this matter.

Bang bang bang...

At this moment, pillars of light surged up in the city of nothingness, as if something was erupting.

At this time, Li Feng, who was practicing above the City of Nothingness, had reached the state of selflessness.

With the operation of Tianyuan Corpse Refining Technique, endless death energy, Yin energy, and corpse energy entered his body, and the Yin fire in his body became bigger and bigger.

As a last resort, Li Feng could only use the Nine Heavens Heart Sutra to convert the yin fire in his body into yin attribute essence.

There is no way, given Li Feng's situation, if there is too much Yin Fire in his body, he will definitely die.

boom!

Finally, after refining enough death energy and yin energy, Li Feng's Tianyuan Corpse Refining Technique broke through to the sixth level.

"Very good."

Li Feng breathed a sigh of relief and prepared to look for Jin Ling.

But at this moment, Li Feng found himself in the sky above the City of Nothingness. Endless Yin Qi and other energy gathered towards him. An energy light film formed around him, and the endless energy impacted his body.

Body.

"No, how could this happen..."

Li Feng was dumbfounded.

Continue to practice Tianyuan Corpse Refining Technique?

God knows how much energy there is in this city of nothingness. Even if he practices with all his strength, he can't refine such powerful energy. What's more, even if he can refine it, he doesn't have time to refine it. He only has one hour.

, twenty minutes have passed now. In the next time, he must find Jin Ling as soon as possible and leave the City of Nothingness.

Rumble…

At this moment, endless energy surged in, energy that tore apart the heaven and earth, and thousands of lightnings struck at him like a storm.

"My life is at risk!"

Although Li Feng is desperate, he will never sit back and wait for death. Even if he dies, he will not sit still and wait for death.

"roar!"

At that moment, Li Feng shouted loudly, the true energy in his body surged, and the true energy in his dantian came out.

He held the blood-transforming knife in both hands, preparing to use the blood-transforming knife to split the energy light film and rush out.

But at this moment, a shocking scene happened.

boom!

In an instant, a dazzling light appeared in the blood-transforming knife in Li Feng's hand.

The next moment, energy from all directions converged crazily towards the Blood Transforming Knife in Li Feng's hand. For a moment, the situation changed color, the ground shook, and it seemed as if the entire world was about to collapse.

At the same time, the unparalleled sword energy emitted by the blood-changing sword actually absorbed the energy that was sweeping in.

Is this the blood-changing knife evolving and repairing?

Li Feng thought of Death Valley and the sea of ​​blood in the Demon Realm.

In the beginning, the blood-changing sword evolved into a second-grade spiritual weapon in Death Valley, and evolved into a third-grade spiritual weapon in the sea of ​​blood in the Demon Realm.

Therefore, Li Feng knew that his blood-changing knife could be repaired and upgraded.

However, he has not been able to find a way to upgrade the Blood-Transforming Sword, so the Blood-Transforming Sword has always been a third-grade spiritual weapon.

Could it be that the energy here can upgrade the Blood Transforming Knife?

At this moment, Li Feng was surprised and happy.

If the blood-changing knife really recovers to the power of a fourth-grade spiritual weapon, it will be an unprecedented good thing for him.

Rumble…

Countless energy storms swept through and were absorbed by the blood-changing knife in an instant.

At this moment, the Blood Transforming Knife was vibrating.

It also indirectly saved Li Feng's life.

This undoubtedly allowed Li Feng to escape death again.

In order for the Blood-Transforming Knife to evolve, Li Feng was suspended in the void, and endless energy converged on the Blood-Transforming Knife in his hand.

The dazzling blood light released by the blood-changing knife is hazy and gives people an unreal feeling, but the fierce murderous aura it reveals makes people tremble from the depths of their souls.

Li Feng's intuition told him that the blood-transforming knife in his hand was no less powerful than Mu Jiajia's iron spear. It was definitely a peerless weapon.

However, Li Feng was not happy for long, as a new crisis appeared again. Because the energy gathered was too huge, and in the City of Nothingness, the power was surging, and the spiritual energy of heaven and earth was extremely strong.

All kinds of energy, the spiritual energy of heaven and earth gathered together crazily, making the void around Li Feng seem to freeze. It also produced an extremely strong pressure on Li Feng.

At this moment, the bones in Li Feng's body crackled under the pressure, as if they were about to shatter at any time.

"roar!"

Li Feng roared and tried his best to resist the pressure. However, as the energy around him continued to gather, the pressure he endured continued to increase. In the end, his true energy could no longer be released outside his body.

.

"Damn it, I can't hold on any longer."

Li Feng's face turned pale.

The blood-changing knife was about to upgrade and evolve, but he was about to be squeezed to death by the endless energy sweeping in.

The unimaginably powerful and terrifying pressure made Li Feng feel that his whole body was being continuously impacted by mountains.

Even with Li Feng's physical defense and Li Feng's endurance, it is still unbearable.

At this moment, streams of blood flowed out of his pores.

This is the reason why the huge energy was absorbed by the Blood-Transforming Knife. Otherwise, Li Feng would not even have any dregs left now.

It can be said that at this moment, Li Feng was at a critical moment of life and death.

what to do?

Li Feng's mind was spinning rapidly.

Put down the Blood Transforming Knife and leave?

It was not that Li Feng had never thought about it, but there was terrifying energy all around him. How could he leave? How could he leave?

Moreover, if it weren't for the fact that he was beside the Blood-Transforming Knife and most of his energy was lost by the Blood-Transforming Knife, his situation would be even worse than it is now. If he let go of the Blood-Transforming Knife, then even the final guarantee would be gone.

It's a pity that here, he can't enter the Xuanling Realm and the Ten Thousand Spirits Map. If he can enter the Xuanling Realm and the Ten Thousand Spirits Map, he doesn't need to worry now.

Unfortunately, in this desperate situation, Li Feng couldn't think of any good solution.

Are you going to die here?

"No, we have to find a way."

Li Feng was not willing to die here, so even if there was no other way, he could only think of a way.

"It seems that this is the only way."

Li Feng's eyes flashed with determination.
