Yuan Feng is a smart man. After thinking of various ways to break the barrier to no avail, he suddenly thought of a possibility.

Judging from the current situation, this blue light barrier must have a steady supply of energy, and as long as this energy supply is cut off, it seems that all problems will be solved!

Judging from the situation in this cave, it seems that the only ones that can provide energy support for the light curtain are the energy crystals inlaid on the cave wall.

After thinking of this, Yuan Feng issued a production order to Xiao Ba without saying a word, and then Xiao Ba produced large numbers of monsters and began to dig out the crystals in the entire cave.

In Yuan Feng's plan, these crystals were not to be missed, but now that these crystals seemed to be connected to the light curtain barrier, he was even more determined to dig up all the crystals here.

Xiaoba produced a lot of magical beasts this time. Each magical beast was attached to the cave wall, and he carefully dug out each crystal treasure. These crystal stones were inlaid very solidly, and they could not be dug out just by digging, even if they were

The magical beasts in the Cave Heaven Realm of Great Perfection require a lot of thought.

Of course, he also sent out several new disciples. Even the Golden-haired Rat with the weakest combat ability was pulled out by him to work as a coolie. Of course, he himself was not idle either, and also joined in the mining of crystal stones.

Among the army.

The entire cave became lively in an instant, and the sound of clanging could be heard endlessly. Yuan Feng had no time to put away the excavated crystals. Soon, the entire cave floor was filled with crystals.

It's extremely spectacular.

This is a big project. If you want to dig out the crystals piece by piece, even a strong man like Yuan Feng needs to put some thought into it. As for those Warcraft, of course, it is no exception.

Yuan Feng was absorbed in the joy of digging. At the same time, outside the canyon outside the cave, the two direct disciples of Liuhe Hall were already waiting impatiently.

"What's going on? It's been so long, why is there no movement at all? Could it be that some accident really happened?"

Outside the canyon, Li Xian and Bai Ling were already waiting impatiently. More than a full day has passed since Yuan Feng and his party entered the cave. Logically speaking, no matter what treasures are in the cave, these ten

People should also be able to get it and return from it.

However, for more than a day, the group of people was like a meat bun beating a dog, with no return.

They didn't care about the life and death of the ten new disciples, but they were still thinking about the treasure in the cave. If the ten people didn't come back, they would have no chance of getting the treasure inside.

"Senior brother, what should I do? There is no movement at all. Could it be that the ten of them don't want to come out?"

Bai Ling's pretty face was also full of anxiety. It wasn't like he couldn't get in. At this moment, ten new disciples entered the cave, but after entering, there was no movement at all. This is

The most worrying thing.

If these ten new disciples really got the treasure inside and then don't want to come out, then they really have no choice but to stay outside and wait for the ten guys inside to finally appear.

"Probably not. With their little strength, they would never dare to have such an idea. It seems that the cave is not simple. Maybe these ten guys encountered some kind of ambush.

"

Li Xian raised his eyebrows, but he didn't think that Yuan Feng and his group dared to do anything disobedient. When he thought about it, either the group was in trouble and was trapped in the cave and couldn't get out, or these people had already

If you die in it, you will never come out.

There are two possibilities, each of which is not small. As for what the situation is, he doesn't have clairvoyance, but he can't see it too clearly.

"Just wait a little longer. Even if there is danger inside, it won't kill all ten of them. It's probably delayed by some circumstances."

After thinking about it, Li Xian still felt that the ten new disciples should have been delayed by some circumstances. Otherwise, even if they encountered danger, all ten of them would not be killed.

"Okay, let's continue to wait. If you still don't come out, then we will go back and find some new disciples. No matter what, these people can enter the canyon."

Bai Ling couldn't think of a better way. For now, it seemed that they could only continue to wait. After all, they had only waited for one day, but it was not a long time at all.

Moreover, they cannot leave easily at this time. After all, if they leave and the ten new disciples come out again, wouldn't they lose both their people and their wealth?

Li Xian and Bai Ling began to wait anxiously, but at this moment, Yuan Feng in the cave was already very busy.

After deciding to excavate the crystals on the cave wall, Yuan Feng ordered Xiaoba to produce almost tens of thousands of cave heaven realm monsters. After all these monsters were put into action, the efficiency was very high.

At the beginning, Yuan Feng also participated in the operation of digging crystal stones, but in the end, he simply stopped taking action and simply collected the dug crystal stones everywhere. At this time, in his cave world

, God knows how many precious crystals there are already.

For him, ordinary treasures are really unattractive, and these crystals are definitely what he needs most right now. Firstly, these crystals can provide energy for cultivation. Secondly, these things are arranged by him.

It was an excellent material for the Xuan Formation. He wanted to try it now. If he used these special crystal stones to arrange the Nine-Meandering Yellow River Formation, how terrifying its power would be.

The Jiuqu Yellow River Formation is greatly influenced by the formation of crystals. The power of the profound formations made of Yin Yang Stone and Wuji Stone are simply worlds apart, and these colorful special crystals are more powerful than Wuji.

Stones are countless times more powerful, so naturally, the mysterious formations constructed with these crystal stones will be even more powerful.

When almost all the crystals in the cave had been excavated, Yuan Feng came to the blue light curtain deep in the cave again and observed the blue light curtain.

"It seems much weaker than before. It seems that the crystals in this cave are really the energy source of this light curtain. Now that there is no energy source, I want to see how you can stop me."

Looking at the blue light barrier in front of him, Yuan Feng couldn't help but reveal a happy smile on his face.

His guess was obviously correct. The current blue light barrier should indeed be connected to the crystals in the cave. But now that there is no energy provided by the crystals, the blue light curtain is naturally weaker.

"Xiao Ba, tell them to work harder and dig out all the energy crystals for me. I will break the barrier of this mysterious formation now."

The more he felt that the barrier of the mysterious formation was loosening, the more urgent Yuan Feng became to break the formation. At this moment, he wanted to break the barrier immediately to see what was inside.

As the order was issued, Xiaoba and the monsters accelerated again in an instant. For Xiaoba, even if all these monsters died of exhaustion, he could still produce a new batch of monsters, and his army of monsters would always be

Inexhaustible.

As more and more crystals were removed, the entire cave became pitch black, and the spiritual atmosphere in it slowly disappeared. At this moment, in the cave, except for the blue light curtain deep in the cave,

Outside, there is nothing unusual about it.

When the last crystal was removed by the monster and handed over to Yuan Feng's hands, the entire cave had become pitch black. Fortunately, Yuan Feng was not affected by the light, so he did not feel anything wrong.

.

"Xiaoba, change the batch of monsters and let's continue to eat!!!"

After all the crystals were in hand, Yuan Feng asked Xiaoba to swallow up the group of diggers without saying a word, and replaced them with a group of monsters aimed at eating the energy light curtain.

Different Warcraft have different abilities. The mining type of Warcraft is responsible for digging. Now that we are going to eat the energy enchantment, of course we must choose the Warcraft according to the energy enchantment.

Not long after, Xiao Ba replaced a batch of magical beasts for Yuan Feng, and after this new batch of magical beasts appeared, they directly attached themselves to the energy light curtain and began to eat it again.

His mind completely sinking into the energy barrier, Yuan Feng carefully observed the changes in the energy barrier. This time he wanted to see where the energy barrier would get energy supplements without those crystal stones providing energy.

As time goes by, one after another, magical beasts die because of eating the energy barrier. However, every time a magical beast is lost, Xiaoba will make up for it immediately, and under such alternating gnawing, it is almost visible to the naked eye.

, the entire light curtain is getting darker and darker, and the toughness on the light curtain is also becoming weaker and weaker.

"It's almost done. Work harder and chew up this damn energy barrier for me. Let me see what is behind this energy barrier!!"

Seeing the energy of the energy barrier being neutralized by the lives of one monster after another, Yuan Feng's eyes became brighter and brighter. He knew that soon, all the scenes behind the energy barrier would be presented to him.

in front of my eyes.

"Buzz!!!"

I don't know how long it took, but at a certain moment, in front of Yuan Feng, the blue energy light curtain suddenly trembled slightly, and then, the entire light curtain finally completely dissipated like ice and snow melting.

"opened!!!"
Chapter completed!
