Sun Xiaofei also felt the aura coming from all around. For a moment, he was as happy as a spring breeze.

However, she didn't know that Zheng Yuan played a large part in it. She thought that it was the effect of the spirit gathering array.

She couldn't help exclaiming: "is this the legendary spirit gathering array? It's really powerful. If you practice in the spirit gathering array, you won't be afraid of insufficient aura. "

She didn't think much any more. She quickly gathered her mind and practiced with all her heart.

In the blink of an eye, seven days passed.

Sun Xiaofei finally advanced from Qi training level 7 to Qi training level 8.

She had an unspeakable surprise.

She thought that it would take at least three months for her to reach the eighth level of Qi training.

I didn't expect that cultivation in the spirit gathering array could progress so quickly.

Now she really realized the magic of the spirit gathering array.

At the same time, her heart to Zheng Yuan more admiration.

She never thought that a foundation builder could set up a spirit gathering array.

Sun Xiaofei stopped practicing, opened his eyes, peeped 15 steps away, and looked at Zheng Yuan who was practicing wholeheartedly. He said in his heart, "where is the sacred elder brother Zheng Yuan? Why is the array so powerful when you are young? "

Before that, all the powerful mages she met were old men in their 50s and 60s.

So Zheng Yuan made her feel amazing.

All of a sudden, Zheng Yuan's whole body turned red, and he kept emitting white heat.

Even sun Xiaofei obviously felt a burst of heat.

Sun Xiaofei was startled at first, and then realized that he was at the last moment of promotion, so he let go.

In her heart, she got angry with him: "brother Zhengyuan, come on."

She no longer hesitated, closed her eyes and continued to practice.

However, she suddenly found that now the aura has become a little weak, compared with before, the difference is very big.

She couldn't help but wonder: "how come after seven days, the aura has become so little? Is there something wrong with the spirit gathering array? Or is it because there's too little aura nearby, and it's gone after being sucked by the spirit gathering array? "

She couldn't think of a reason for it, so she was too lazy to think about it.

The reason why aura became rare was of course caused by Zheng Yuan.

In seven days, he had absorbed all the aura within 30 Li.

He's now at the critical juncture of advancement.

He is constantly speeding up the absorption of aura into the true yuan.

All true yuan in his mind, constantly to the Dantian.

His body is also red and hot with the progression.

About an hour later, Zheng Yuan finally broke through the final hurdle and reached the fourth floor of Zhuji.

The fourth floor is the middle stage of foundation construction.

The meridians in Zheng's protoplasm have expanded and strengthened three times.

For a moment, he felt full of explosive power.

He was surprised to find that his skill had been improved nearly three times.

It was not built in the middle of foundation construction.

Although the difference between the third floor and the fourth floor is only one level, the overall strength has increased more than three times.

Zheng Yuan leaped up and roared up to the sky.

Sun Xiaofei heard Zheng Yuan's howling, stopped practicing, opened his eyes, stood up and said happily, "brother Zheng Yuan, congratulations on your promotion."

Zheng Yuan said with a smile: "happy together."

Sun Xiaofei praised: "brother Zheng Yuan, it's amazing that the spirit gathering array can promote people in such a fast time."

Zheng Yuan said: "of course, the spirit gathering array is one of the four."

Sun Xiaofei suddenly thought of something and sighed a little dejectedly: "it's a pity that there's no Aura now, or you can practice well for a period of time."

Zheng Yuan said, "no need to practice. We can go out now."

Sun Xiaofei was a little surprised and said, "out? Has feiyunzi left? "

"I don't think I have left yet," Zheng said

"So how do we get out?""Just go out with your feet."

"But..."

Zheng Yuan said with a sly smile: "no, but he can't stop us from leaving."

After reaching the middle stage of foundation construction, Zheng Yuan had the confidence to fight against feiyunzi.

His current skill may be a little weaker than that of feiyunzi, but relying on the hand of heaven prison, his overall strength can already surpass that product.

When building three layers of foundation, he can make feiyunzi seriously injured.

Now his skill has been improved three times. It's easy to deal with him.

Zheng Yuan said nothing more, took back the flag of the spirit gathering array, and then went to the layman.

Sun Xiaofei took a look at Zheng Yuan's back and wondered: "what is brother Zheng Yuan thinking? Why are you planning to go out all of a sudden? Does he think that if he doesn't see them for a few days, feiyunzi will be very kind and let them go? "

However, she knew that Zheng Yuan would not be so brainless.

So she quickly denied the idea.

Then she thought, "does elder brother Zheng Yuan think that he can fight against feiyunzi when he is promoted to the fourth floor of Zhuji?"

The more she thought about it, the more likely it was.

Only in this way can we explain Zheng Yuan's action.

She couldn't help sighing.

She knew that although the fourth floor of the foundation was more powerful than the third floor, it was still the difference between heaven and earth.

Now Zheng Yuan goes out now, it is still impossible to defeat Fei Yunzi.

She felt that Zheng Yuan was a little hasty.

However, she didn't say anything more, so she ran after her.

No matter how Zheng Yuan chooses, she will give him her full support.

Not long after, Zheng Yuan came to the mouth of the valley.

He removed the four level prohibition and three level defensive array, and then walked out of the valley with sun Xiaofei.

Feiyunzi is still sitting under the big tree not far away.

See Zheng Yuan two people come out, he can't help a Zheng.

He did not expect Zheng Yuan to take the initiative to withdraw from the battle.

He jumped up with excitement and grinned: "boy, you can't help coming out at last. Ha ha, it depends on where you are going to escape."

"Run away? Why should I run away? " Zheng Yuan a face doubts of way, "I come out just want to look for you to exchange well, didn't want to escape."

Flying cloud son Yin side of smile way: "very good, what I like most is to deal with the person of understanding, I will certainly leave a whole corpse for you later."

Zheng Yuan light way: "that thanks."

Feiyunzi's eyes fell on Sun Xiaofei, and a trace of immorality flashed in his eyes: "little girl, do you want to die or live? If you don't want to die, follow me, and I'll save your life. "

Sun Xiaofei's eyes flashed a trace of disgust, scolded: "abnormal idiot."

Then he came to the back of Zheng Yuan.
