Feel the white flames burning in the space of your heart.

Zheng Yuanpei held his breath, he vaguely guessed that Shen Feng had hidden the temperature of this heavenly fire and changed his breath.

Even so, this kind of Heavenly Fire gave him a feeling of heart palpitations, and he was sure that the level of this Heavenly Fire would not be low, but he would never have thought that the flame in his heart space now was the legendary Sky Devouring White Flame.

He had just wondered if Shen Feng would also be a third-grade heart refiner?

But right now, he completely denied this speculation, after all, he himself was also a third-grade heart refiner, if Shen Feng was only a third-grade, then how could he see his physical condition?

Under normal circumstances, Zheng Yuanpei's thinking was not wrong at all, but Shen Feng obtained the heart refining inheritance of the mysterious person Ge Wanheng, and he was naturally much stronger than the three-grade heart refining master in one heavy day.

"Could it be that he is a fourth-grade heart refiner?" Zheng Yuanpei swallowed with difficulty.

It is rumored that in one day, the strongest is only a fourth-grade heart refiner!

Shen Feng was able to reach the sixth-order inscription master at the same time, and also stepped into the fourth rank on the way to refining the heart, which really made Zheng Yuanpei unbelievable!

All of a sudden.

Zheng Yuanpei frowned, a hideous color appeared on his face, and he felt a burst of expansion in the space of his heart, as if there was a tendency to explode.

Shen Feng then said, "Hold back, you will suffer even more pain next." ”

He sensed the cracks in the space of Zheng Yuanpei's heart, and kept controlling the Sky Devouring White Flame to move in it.

Now if you want to repair these cracks, you can only use the Sky Devouring White Flame to slowly polish the space of Zheng Yuanpei's heart, and all the cracks in it are polished together.

This is a great test of Shen Feng's meticulous ability to control the Heavenly Fire, and the control of Xuan Qi must also be extremely accurate.

When he didn't stop polishing with the Sky Devouring White Flame.

The hideous color on Zheng Yuanpei's face became more and more intense, he was like a demon in hell at the moment, and the sharp pain in the space of his heart made him constantly snort in his throat.

However, this old man regarded the journey of heart refining as more important than life, so no matter how painful it was, he had to grit his teeth to support it.

Generally speaking.

After the first opening, the space of the heart will be forever fixed, and the second opening will not be possible.

But right now, when Shen Feng was helping Zheng Yuanpei polish the space of his heart and trying to close the cracks on it, he unexpectedly found that under his own polishing, a subtle change was faintly undergoing in Zheng Yuanpei's heart space!

What the hell is going on?

After thinking for a few seconds.

Shen Feng wondered if it was because of the White Flame that swallowed the sky? It could be this legendary Heavenly Fire that could break the constant and unchanging rules.

Feeling that some cracks were closing, Shen Feng planned to be a good person to the end, ready to make sure, whether he could really help Zheng Yuanpei's heart space to change again?

"You will show me your own heavenly fire powder ding, condensed on the outside. Shen Feng ordered.

Zheng Yuanpei, who was enduring the pain, couldn't think of what Shen Feng was going to do, so he gritted his teeth and condensed his Heavenly Fire Powder Ding.

After Shen Feng finished feeling this Heavenly Powder Ding, he threw himself into polishing it again.

And Zheng Yuanpei didn't have the energy to pay attention to the space of his heart, he was desperately enduring the pain right now.

As time passes, slowly.

Beads of sweat kept coming out of Shen Feng's forehead, and even his clothes were soaked, as if he had been fished out of the lake.

As for Zheng Yuanpei, he was no better than Shen Feng, after enduring the pain for so long, his breath seemed a little weak.

About another half hour later.

Shen Feng's palm removed the position of Zheng Yuanpei's heart, polishing all the cracks in his heart space together, and he really did it, changing Zheng Yuanpei's heart space to a certain extent, which made him secretly shocked.

"Okay, you can continue to move forward on the path of heart refining in the future. Shen Feng exhaled and said.

Zheng Yuanpei also felt that the pain in the heart space was slowly disappearing, and he sensed the changes in it for the first time, and he found that all the cracks inside had indeed disappeared.

And his heart seems to have become a lot lighter.

He wanted to immediately refine a three-grade spiritual liquid to give it a try, but when he condensed the Heavenly Fire Powder Ding in the space of his heart, the whole person was instantly stunned.

Since Shen Feng's transformation of the heart space was very small, Zheng Yuanpei didn't find anything just now.

If today's gunpowder tripod is condensed in the space of the heart, he can immediately discover the subtle changes in the space of his heart.

Previously, the compatibility between the Heart Space and the Heavenly Powder Ding was only forty percent at most.

After all, after the space of the heart is opened, it will be completely frozen, and the Heavenly Flame Ding can be perfected.

In one day, it is already very good to be able to have this kind of fit.

And at this moment.

After Shen Feng's slight changes, the compatibility between Zheng Yuanpei's heart space and the Heavenly Flame Powder Ding definitely rose from forty percent to sixty percent.

It has improved so much fit, which means that Zheng Yuanpei will be able to refine the spiritual liquid more easily in the future, and he will definitely be able to go further on the road of refining the heart.

He was short of breath and felt the changes in the space of his heart, and his eyes were fixed on Shen Feng.

Doesn't it mean that the space of the heart can only be opened up once? even the heart refiners of the second and third heavens cannot open up the space of the heart a second time.

After Shen Feng noticed Zheng Yuanpei's gaze, he said casually, "I just helped you transform the space of your heart. ”

Transform the space of the heart?

This sentence sounds extremely bland, but to a heart refiner like Zheng Yuanpei, this sentence is really too domineering and too bullish!

Let's ask, who else in the entire Heavenly Domain dares to say this sentence so softly?

Zheng Yuanpei didn't rush to try to refine the spiritual liquid, he sat on the ground, sometimes laughing wildly, sometimes crying bitterly......

Emotions are constantly changing, crazy, completely like a madman.

In fact, Zheng Yuanpei was so happy and excited, the fit jumped from 40% to 60% all of a sudden, this is what he wants to see in his dreams!

Now that everything has happened in reality, his emotions that make him happy for a while are out of control.

When his gaze looked at Shen Feng again, his eyes were full of respect and admiration, he could change his heart space so easily, what grade of heart refiner was Shen Feng? he didn't dare to guess at all!

This moment.

He just knew that he couldn't miss this opportunity!

"Bang! bang!"

Zheng Yuanpei knelt down towards Shen Feng and kowtowed three times, he knocked very hard, and even the stone bricks on the ground were smashed by his head.

He didn't care about the bloody brain, pleaded with great respect, and said, "Senior, I know it's wrong. ”

"I apologize here for all the offenses I have taken to you before. ”

"Please forgive me!"
