The sky was slightly bright, and Pang Feng's "Heaven and Place" mental method was running to the most critical juncture.

In the spring in the villa, the spring water is tumbling, and with the tumbling spring water, the rolling spiritual power is constantly breeding, Pang Feng opened his mouth, the tumbling spring water was beaten, and then the surrounding spiritual power instantly became thin.

At this time, Pang Feng was like a thirsty spirit-eating beast, the Triple Transformation Dragon Array was running, and all the spiritual power generated was devoured by him.

"Whew!" he exhaled.

The breath penetrated the window of the villa like a white practice, and **** all the way to the grass outside the villa.

Spit it out again!

In the same way, Pang Feng devoured the spiritual power generated by the operation of the large array again, and the spiritual power that had just been filled in the villa became thin again, and the tumbling spiritual spring was actually in a state of stagnation, and this time it seemed that it could not be completed.

Pang Feng's hand flipped over, and there was an extra "Tongling Jade" in his hand.

The emerald green Tongling Jade beat in the palm of his hand, and the verdant brilliance became dim at a speed visible to the naked eye, and the spiritual power in the "Tongling Jade" was introduced into his body by Pang Feng.

"Whew!" exhaled again.

A white practice once again penetrated the villa, as long as ten zhang away, which was very good-looking.

"Click, click, click!"

After Pang Feng spit out this breath, the joints on his body suddenly sounded like fried beans, from his hands to feet, the joints of his limbs began to shatter and explode, and then there was a crisp pop in the bones of his body, and then his head made a shattering sound.

If someone sees Pang Feng at this time, they will find that his whole person is constantly changing, becoming fat for a while, thin for a while, his face is high and bulging for a while, and his eye sockets are deeply collapsed for a while.

This kind of change is incredible, and in his meridians, the pure spiritual power is surging, like the calm lake water being stirred by the wind and rain, and the agitated spiritual power beats Pang Feng's body, and Pang Feng's body has undergone incredible changes.

Every bone of his has become like a life, the bones are frantically devouring the spiritual power in the meridians, as the spiritual power devoured more and more, the bones of the body are undergoing incredible changes, every molecule in his bones has become different from before, and the whole bone has become harder, denser, and stronger.

The opportunity to break through came, Pang Feng stepped into the fourth level of Qi training, and the fourth level of Qi training was the beginning of bone replacement, and with the incredible changes in Pang Feng's body, his breathing became more and more frequent and fast.

At this time, his body's thirst for spiritual power was stronger than ever.

He continued to do spitting, and at the same time, the spiritual energy in the "Tongling Jade" in his hand was continuously absorbed by him.

Powerful spiritual power supports his body in an incredible transformation.

There are three realms of bone change, the first realm is the beginning of bone change, also known as "iron bone", the second realm is the bone change, also known as "jade bone", and the last realm is the completion of bone change, also known as "spirit bone".

Generally speaking, it is best to complete each realm overnight, and it is most taboo to break in the middle, because after the bone change, the monk is completely reborn into a spirit body, if there is an interruption in the process of bone change, or the bone change is completed several times, the transformation of the body will be flawed.

A flawed body will not only be weakened in strength, but it will also bury a great hidden danger for future cultivation.

Now Pang Feng is at the most critical time.

"I'm a grass, my spiritual power is not enough!" Pang Feng sucked the spiritual power dry in one breath, he had to ensure the intensity of the spiritual power stirring in the meridians.

Every bone in his body needs to devour spiritual power in the process of change, and after the spiritual power runs in the meridians for a week, one-third of the spiritual power is devoured, and the speed of such devouring is too terrifying.

"Tongling Jade!"

Pang Feng shouted, he felt that his replacement had reached the most important time.

He absolutely did not allow the first bone change to be completed in several parts, the record in the inheritance, the bone change must be done overnight, such a bone change is called perfect bone change, only the perfect bone change can have hope to walk towards the door of the avenue.

At the last moment, Pang Feng couldn't take care of it, and he could only replenish his insufficient spiritual power through the "Tongling Treasure Jade".

The green psychic treasure jade brilliance darkened again, this time the chalcedony completely lost its brilliance, and there was a "click" sound, and a piece of psychic treasure jade was actually cracked into four or five petals from the middle, and the psychic treasure jade was broken!

Pang Feng felt a pain in his heart, and at this time, the dragon transformation array was running again, without pause, and the spiritual power in Pang Feng's meridians rose to its peak, and his last bone changes were in the spine of his back.

"Click, click, click!"

Pang Feng could clearly feel the spine chains on his back exploding one by one, and the broken spine bones were strong devouring spiritual power.

The spine was all opened, and the bones could not support Pang Feng's body, and Pang Feng's body collapsed uncontrollably on the ground, turning into a mess of mud.

"Whew!"

Pang Feng collapsed on the ground, exhaled hard, he sucked the spiritual power in the villa dry, the spiritual power in the meridians was replenished, the back spine "clicked", a chain was opened after the bone transformation was completed, and it was locked again, his paralyzed body shook and moved up a point.

"Click!" Another spine chain was locked, and Pang Feng's body moved up again.

"Click!" "Click!"

As the transformation of the spine bones was completed, and then locked, Pang Feng's body continued to move upward.

The last bone chain made a "wow" sound, the chain was locked, Pang Feng's body became straight again, and he spit out a mouthful of "turbidity" in his chest.

A long white line shot quickly into the distance, penetrating beyond the courtyard wall of the villa that was difficult to see.

A burst of ecstasy surged over Pang Feng's heart, and he jumped up from the ground, raised his hands and legs, and felt that his body was completely renewed.

The fourth re-alignment of Qi training is small!

The bones of Pang Feng's body were no longer mortal bones, but became iron bones, and the hardness and strength of the bones became incredible, and his strength soared tremendously.

"Huh!" Pang Feng pulled out a long knife from several cases.

This knife is a Tang knife given to him by Chen Ying, which is made by a famous artist according to the casting process inherited from ancient times, and it is very sharp.

The long knife is out of the sheath, and the chill is forested.

Pang Feng picked up the long knife and slashed it on his arm, the long knife made a "clang" sound, Pang Feng's arm was intact, his skin membrane had strong toughness, leaving a deep red mark and not broken, and his bones were like iron, and there was no damage in the slightest.

"I'm the second grass, the fourth weight of Qi training is against the sky, after the bone change, I am not afraid of ordinary thermal weapons, even if it is a heavy sniper!" Pang Feng said secretly in his heart, the confidence in his heart was extremely high, this time the perfect bone change, it was very thrilling, but in the end, I was very lucky.
