Aircraft is not only extremely fast, but also the most difficult to refine among all the real tools, so it is very rare and precious.

Generally, only the strong above Yuanying have the ability and financial resources to get it.

Zheng Yuan felt envious: "if there is a flying machine, it will be more convenient to go out in the future, and you can take qingran with them at any time."

He planned to get an aircraft anyway.

Suddenly, he thought of something.

UFO is often seen on the earth. Isn't it the aircraft of the practitioners?

He knows that if the aircraft is fast enough, it can cross space accidentally.

So the more he thought about it, the more likely he felt it was.

Zheng Yuan didn't think much about it any more and continued to hurry up.

Four days later, he came to an unknown mountain.

He suddenly found a small hill full of aura.

This place is very suitable for cultivation.

So Zheng Yuan didn't hesitate any more. He set up a spirit gathering array on the hill, and then sat in the heart of the array to practice.

Although he was in a hurry to duanyun mountain, he knew that the key was to improve his cultivation.

Duanyun mountain is extremely dangerous. If the cultivation is too low, it is easy to encounter accidents.

Therefore, as long as there is enough aura, he will stop to practice.

With the help of the spirit gathering array, the auras all around gathered continuously, and finally formed a huge aura vortex in mid air.

In fact, even if he didn't use the spirit gathering array, Zheng Yuan could produce spiritual vortex in his own cultivation.

However, it's not as big as the spirit gathering formation.

After the collection of aura, it kept pouring into Zheng Yuan's body like a tide, and then it was transformed into true yuan.

The true elements in Zheng Yuan are more and more accumulated and stronger, and the meridians become larger and stronger with the refining of true elements.

In the blink of an eye, three days passed.

Zheng Yuan successfully reached the second floor of the foundation.

His current cultivation speed is abnormal.

It should be noted that for ordinary practitioners, it takes at least three years from the first level to the second level.

It takes at least a month for a genius, and five days even with the help of pills.

But compared with Zheng Yuan, they are far from each other.

The reason why Zheng Yuan is so abnormal is due to the contribution of chaos hell formula.

The secret of chaos hell gives Zheng Yuan the abnormal ability to absorb aura and the speed to transform the real yuan.

So as long as he has enough aura, he can advance crazily.

However, the aura he needed was terrible, more than ten times that of ordinary practitioners.

That is to say, ordinary practitioners need a piece of aura, he needs ten.

Of course, the truth element formed by this way is very powerful.

This is why the power of Zheng Yuan is so much stronger than that of ordinary practitioners of the same level.

Although he is only in the early stage of foundation construction, his strength is no less than that of any later stage of foundation construction, or even the perfect generation.

However, it also makes it very difficult for him to find a place with enough aura.

In other people's eyes, aura is sufficient, but in front of Zheng Yuan, it is insufficient.

For example, the small hill bar now seems to have a good aura, but there is not much left after Zheng Yuan's absorption.

Originally, the aura here could be used for several years if it was practiced by ordinary builders.

After about four days, Zheng Yuan successfully reached the third floor of the foundation.

He wanted to be promoted to the fourth floor of Zhuji, but there was not much aura around him.

Although the difference between the fourth floor and the third floor is only one level, the power can be compared by firefly and candle.

Because the fourth floor of the foundation belongs to the middle stage of the foundation construction, so the strength will be greatly improved.

Zheng Yuan sighed: "it seems that it will take some time to advance to the middle stage of foundation building."

Zheng Yuan didn't think much about it any more, and began to build it steadily.

It only took him two days to completely stabilize the three-layer foundation.After that, he got up and removed the spirit gathering array.

All of a sudden, he found that all the plants around him became low and not a bit angry.

He knew it was because of lack of aura.

Zheng Yuan couldn't help but exclaim.

Now he finally knew how terrible the speed of absorbing aura was.

He knew it would take at least ten years for the place to return to its former state.

He took a look at the plants around him and said apologetically, "I'm sorry, brother grass and sister tree."

Zheng Yuan no longer hesitated, and continued to set out for duanyun mountain.

After about three hours, it was completely dark.

At this time, Zheng Yuangang came to a broken temple.

There was a bright flash of fire.

Someone's already in there first.

Then, a burst of male and female voices came out.

Zheng Yuan opened his mind and went in. There was a fire in the broken temple.

I saw a man and two women sitting around the fire eating a big hare.

The man was sitting in the middle, about twenty years old, well-dressed and handsome.

The girl sitting on the left side of the man is about 17 years old. She is dressed in black and looks beautiful.

The girl sitting on the right is 16 years old, wearing yellow clothes, bright eyes and white teeth.

When Zheng Yuangang was about to walk in, he suddenly heard the man give out a loud drink: "stop, don't come in."

Zheng Yuan was slightly surprised. He did not expect that this man, who was not as beautiful as a woman, was so domineering that he would not let anyone in even a broken temple.

However, he was not the one who was arbitrarily ordered, so he did not stop and went in boldly.

The man stopped eating rabbit meat, took a very delicate handkerchief, wiped his hands and mouth, and then glared at Zheng Yuan angrily: "asshole, didn't the young master tell you not to come in? You dare to come in and get out of here. "

Zheng Yuan's eyes flashed a trace of discomfort: "this place is yours? Why can't I come in? "

"This is the first thing we found. You are not qualified to come in. Get out of here, or I will be rude."

The man stood up with a chill in his eyes.

The girl in black also stood up and glared at Zheng Yuan angrily: "smelly boy, didn't you hear elder brother long an's words? This place is not a place where you can come in at will. If you don't get out on the count of three, don't blame Miss Bennet for being rude. "

Zheng Yuan is completely speechless. He dares to love these goods. They are all unreasonable. He just came here first and regarded it as his own territory.

He doesn't like to bully people, but he won't let others bully him.

So, he planned to, if these goods dare to make trouble without reason again, then don't blame him for not being polite.

He could see that the man was a five story man.

But I don't care.

With his current strength, let alone in the middle stage of foundation construction, even in the later stage of foundation construction, it is as easy as cutting tofu and hemp grass.
