Although Jin Xingyue tried her best to stop Li Feng, Qin Keqing didn't give her a chance at all. Even though Jin Xingyue yelled and cursed and made all kinds of filthy words, it was a pity that Qin Keqing was too calm and rational, so she was not affected by Jin Xingyue.

The influence of the stars and the moon.

Li Feng soon arrived at the stone trough.

Li Feng looked towards the stone trough and saw rich liquid energy.

What kind of energy is this, Li Feng doesn't know.

But it's strong, rich, and substantial.

"What can this energy do?"

"Absorption and refining?"

"no……"

Li Feng immediately shook his head. Now that his devouring power was limited, such rich energy could not be devoured and refined at all.

But what's the use of this energy if it's not used for devouring and refining?

What container should I use to put it back?

Li Feng thought for a while and felt that this was impossible.

"By the way, the Blood Transforming Knife..."

Li Feng suddenly thought of his blood-transforming knife.

The Blood Transforming Knife is now a fourth-grade spiritual weapon.

His cultivation level is now at the middle stage of the fourth level of the Martial Emperor. According to his leapfrog killing ability, his combat power is already at the early stage of the first level of the Martial Emperor during his peak period. He needs at least a sixth-grade spiritual weapon to match his combat power.

So, at this moment, Li Feng thought of evolving the Blood Transforming Knife.

After all, the Blood Transforming Knife is a broken weapon that can be evolved and restored.

Thinking of this, Li Feng turned his palm and took out the blood-transforming knife.

Whoosh!

As soon as the blood-transforming knife appeared, Li Feng inserted the blood-transforming knife into the stone trough.

boom!

The moment the blood-changing knife was inserted into the stone groove, a dazzling light appeared in the blood-changing knife.

The next moment, all the energy of the stone trough converged towards the Blood Transforming Knife like crazy.

The whole space seemed to be shaking at this moment.

Rumble…

For a moment, the wind and clouds changed color, and the earth shook and the mountains shook, as if the whole world was about to collapse.

At the same time, the incomparable sword energy emitted by the blood-changing knife actually absorbed the energy in the stone tank.

This is the blood-changing knife evolving and repairing.

Back in Death Valley, in the sea of ​​blood in the Heavenly Demon Realm, and in the City of Nothingness, this was how the Blood Transforming Sword evolved and recovered.

It evolved into a second-grade spiritual weapon in Death Valley, evolved into a third-grade spiritual weapon in the Blood Sea of ​​the Demon Realm, evolved into a fourth-grade spiritual weapon in the City of Nothingness, and now it is finally about to evolve into a fifth-grade spiritual weapon.

This surprised and delighted Li Feng.

As early as when Li Feng's combat power broke through to the Martial Emperor Realm, he wanted to evolve the Blood-Transforming Sword. But unfortunately, it was not easy to evolve the Blood-Transforming Sword, and he could not find a way. But now, it is finally time to evolve the Blood-Transforming Sword.

It’s time for the Blood Knife to evolve and resume.

I just don’t know if the energy here is enough.

Of course, in the best case, the blood-changing knife can evolve into a sixth-grade spiritual weapon. After all, this is what he needs now.

Rumble…

The energy liquid in the stone tank became less and less after being absorbed by the Blood Transforming Knife, and the terrifying aura spread. Even Li Feng couldn't stay any longer and quickly retreated.

Swish, swish, swish...

The dazzling blood light and fierce murderous aura released by the Blood Transforming Knife makes one's soul tremble.
