"First of all, all formations are inseparable from the formation eye, and the formation eye is the foundation of a formation. If you want to control the formation, you must first find the eye of the formation, and then use soul power to communicate, so as to achieve the purpose of control. In addition, as far as the concealment formation is concerned, there are two types, one is the shadow hidden block, so that you can't enter, and the other is that you can enter the formation, but you can't see the real thing, and what you can see is illusory. And this formation in front of you is the one that can't be entered. You use your soul power to feel where the soul power in this formation is, as long as you find a little soul power, you can follow the vine and find the gathering place of soul power, which is the eye of the formation......"

Yun Feng followed the prompts of Xuanfeng Medical Venerable and began to feel the existence of soul power in this formation......

But no matter how hard Yun Feng tried and how he tried to find the existence of soul power, he couldn't find it. Suddenly, Yun Feng was a little distracted, and he had the urge to scold Xuanfeng Yizun......

"Be calm, have a state of selflessness, whether there are mountains of gold and silver in the outside world, or life and death, it has nothing to do with you. The most important thing for you is to feel the presence of soul power......"

Xuanfeng Yizun reminded again, obviously a little angry......

Yes, you have to be calm, you have to forget yourself slowly, and you have to feel it carefully......

Ha ha......

Got it!

Yun Feng was suddenly overjoyed and chased after his soul power. The soul power of the formation is like a swimming fish, wandering around, fluctuating.

Hey!

Another wisp was found!

And a wisp!

Soon, Yun Feng discovered the place where the soul power in the mouth of the Xuanfeng Doctor Venerable gathered. I saw the soul power floating in and out, in and out in an orderly manner, like an ant's nest. No matter how many ants go out and how many come in, the anthill still continues to operate in an orderly manner.

It looks extraordinarily spectacular......

"Wrap the soul power group in the middle with soul power, as long as you stop the flow of soul power in and out, this formation will naturally be controlled......"

Xuanfeng Yizun commanded from the side......

Hearing this, Yun Feng didn't dare to be careless, and hurriedly used his soul power to wrap himself in that soul power group. This formation is already an ownerless existence, and the operation is only the operation of the soul power instinct, without a trace of vitality. Yun Feng didn't have much effort, and his soul power easily wrapped the soul power group tightly......

Ah!

How can this be......

Yun Feng suddenly felt that there were thousands of ants crawling around in his soul, itching and uncomfortable......

"Bear with me, and it'll be good after a while......"

Xuanfeng Yizun reminded him again, and there was a sense of schadenfreude in and out of his words.

Damn, you old man, why didn't you say it earlier, let me be a little prepared, you are just waiting to see my jokes. Yun Feng couldn't help but scold Xuanfeng Doctor Venerable in his heart......

"You can save it, the master of this formation is estimated to be dead, and the soul power will only operate independently, and will not resist your invasion, otherwise it will be enough for you to drink a pot......"

Sure enough, it was an old monster, and he actually surveyed this formation so carefully inside and out, even when the master died, he found out. Yun Feng was suddenly afraid, if Xuanfeng Yizun was in a good mood that day and observed himself, wouldn't it be that he had a few hairs and a few grains of rice he had eaten in one meal, he would have known......

"Boom ......"

There was a soft thud......

I saw that the stone in front of Yun Feng's eyes suddenly blurred, first turning into a mist and white. Then it slowly spreads out, revealing a passage that only one person can pass with his head down......

Oh, my God!

There is actually a hidden passage, could it be that there is a treasure hidden inside!

Yun Feng couldn't help but scream and be excited in his heart, and at the same time, he also looked at this formation.

I saw that five quaint array cards were inlaid on the wall of the cave entrance, and then the soul power was skillfully connected here, which formed the formation base of the formation. And the array eye, at this time, was wrapped in the soul power of the cloud wind, staying in mid-air. This concealment formation can be said to be ingenious, very cleverly designed, very simple and practical. If the master enters and exits, use soul power to control the formation to open, and then release the formation after it passes. The formation worked confidently and continued to seal the place, leaving no trace.

At the same time, Yun Feng also discovered that there was another formation next to this formation, which was a spirit gathering formation. That is to say, the entire concealment formation is divided into two parts: concealment and energy supply, the concealment formation shadow is hidden, and the spirit gathering formation supplies a steady stream of aura to support the operation of this formation. In this way, no matter how long the owner is away, the cave will not go undetected......

Yun Feng sighed for a while, but still walked along the cave with anticipatory steps, wanting to find out......

After walking for a while, about a hundred meters, Yunfeng was surprised to find that the cave was wide, and the three of them were in parallel, and there was no problem at all. At the same time, the walls of the cave wall are not as rough as the previous ones, and they are very smooth, and they have obviously been manually repaired......

This aroused Yun Feng's curiosity, what kind of space was this sacred hiding, and how many unknown secrets were hidden in it......

Suddenly!

There is light!

Although it is a little dark, it is very stable, not at all like the torch that Yunfeng is holding at the moment, flickering and erratic......

Carried away by the desire for curiosity, Yunfeng quickened his pace, wanting to find out......

Oh, my God!

Spectacular!

Magnificent!

A huge cave......

It is more than ten meters wide and two feet high, and there is no end in sight,......

The roof of the cave is inlaid with a night pearl at every little distance, illuminating the cave very brightly. This night pearl can automatically absorb the aura in the air and then glow. This is also the miracle of the Creator! So I don't know how many years have passed, but this cave is still like daylight......

Such a precious night pearl is also very valuable, and Yun Feng has an impulse to find a ladder, pry those night pearls down, and take them to Meteor City to buy them, which is enough to make a lot of money for himself......

A path winds its way deeper into the cave, and Ruth is overgrown with weeds and vegetables. The small fences on both sides of the road have decayed and fallen a lot, which is indeed a trace of human habitation, but it has not been taken care of for a long time, and it has been deserted......

Hey!

There is also Pei Yuanju!

This is not only a basic elixir, but also a first-level elixir, and Yun Feng even discovered a second-level elixir, Yan Sunflower......

It's sent!

Haired, developed!

Yunfeng is about to dance and jump......

If you go back to refining the pill, wouldn't it make your strength increase by leaps and bounds? Wouldn't it also make the strength of the people of the Zhang family go to a higher level?

Seriously, Yunfeng is poor now. Most of the elixirs collected every day were refined into pills at night, and then everyone ate them separately to assist in cultivation......
