The real fire burned blazingly, and the surrounding materials continued to fly up, fall into the real fire, undergo the calcination of the real fire, and then melt and change into various shapes.

Immediately afterwards, the Sky-Breaking Sword also began to change little by little under the burning of the real fire.

However, the material of the Heaven-Breaking Sword is too strong. Even if Chen Feng used all his strength, the power of the real fire has reached his current limit. He still cannot smelt the Heaven-Breaking Sword quickly and can only melt it bit by bit.

Refining.

Refining the Heaven-Shattering Sword is destined to be a long process, and Chen Feng is also prepared for this.

He asked Xiaobai to put the Soul-Connecting Pill and Blood Spirit Pill in the training room, not only for them to practice, but also to assist in refining the Sky-Breaking Sword.

And before he went into seclusion, he had told Mu Hongyan and the others not to disturb him.

A week has passed in the blink of an eye, and the energy of the Tongshen Pill and Blood Spirit Pill has been consumed by almost half of Chen Feng, but the harvest is also gratifying.

After a week of sleepless refining, the Heaven-Breaking Sword was finally completely smelted. Next, Chen Feng integrated those auxiliary materials into the Heaven-Breaking Sword.

There are some lines on the Sky-Breaking Sword, which are the marks left by the formation runes.

In addition, the Sky Breaking Sword has also shrunk by a quarter.

However, this is just an appearance. The current Sky-Breaking Sword can change in size and can reach a maximum length of three feet. It is more than enough to carry people flying with the sword.

"Condensation!"

In the training room, Chen Feng's voice rang out, his exhaustion revealing deep joy.

call out!

Astonishing sword energy soared into the sky from the training stone. It was night at this time, and the stars and moon were bright. However, as this sword light flew out, even the light of the stars and moon dimmed.

Between heaven and earth, there is only this sword light left!
