Lu Yun was stunned for a moment, suddenly came to his senses, and hurriedly shook his head: "It's not what you imagined." ”

Wu De and Qingshan obviously didn't believe it, which made Lu Yun lose his temper completely.

He also stopped talking, and began to use the Xuanyuan Sword to cut at the two-meter spirit stone, cutting out pieces of boxy fist-sized spirit stones.

The spirit stone was very hard, it was very difficult for Lu Yun to cut, even when using the Xuanyuan Sword, it took Lu Yun almost a day to cut the spirit stone.

He just arranged the hidden defensive formation, and it was a waste if it was big, and the size of his fist was just right.

The same is generally true for other people to arrange formation patterns, unless they arrange permanent formation patterns, they will use larger spirit stones.

Lu Yun cut a total of more than fifty pieces, and then began to engrave on the spirit stones.

Crooked lines appeared on the spirit stones, and two hours later, he had carved all the spirit stones into the formation patterns.

In fact, this time the array is not so much, only a dozen pieces are enough, and Lu Yun plans to engrave more points in case of emergency.

The spirit stones that were engraved with the formation pattern became the formation platform, and he took out a dozen of them and began to place them around the valley.

When all the arrays were set up, Lu Yun took out the Fuxi gossip, and with a tap of his hand, he connected the arrays together.

In an instant, all the arrays were connected, and spiritual energy flowed in them.

Even the surrounding peaks and valleys are connected, and the hidden defensive formations have been arranged.

Qingshan was outside, and at the moment when the formation pattern was arranged, Lu Yun and Wu De had already disappeared, and it seemed that they were not here at all.

The valley is still a valley, the mountain is still a mountain, but the people are gone.

Aoyama sensed carefully, and he couldn't detect the anomaly here, unless he stepped into the formation, he could not find the problem.

Lu Yun manipulated and took Qingshan in, and Qingshan exclaimed: "The formation pattern is really magical."

Lu Yun shook his head: "This is just one of the simplest formations."

He was right, he was only preliminarily involved in the formation patterns, and he had no deep study at all, so he could only arrange some simple formations.

However, even if it is a simple formation, with the holy weapon of Fuxi Bagua in it, it has become not simple.

What's more, the formation patterns of many sects have long been broken, so there is no need to worry about being discovered by the disciples of the Changbai Sect.

The formation pattern has been completed, and the next thing is to wait patiently, and continue to eat away at the disciples of the Changbai Sect, constantly weakening the strength of the Changbai Sect.

Lu Yun and the three of them waited for two days, and then they saw two Changbai Sect disciples going out, and they seemed to be sneaky.

These two people have a double mountain and river realm, and a mountain and river realm is heavy, Lu Yun and the three of them did not hesitate, directly knocked them out and dragged them into the hidden defensive formation.

The two of them saw their condition clearly, and their faces turned pale.

Lu Yun asked in a cold voice, "Can you participate in the affairs of the Sun Moon City Immortal Dao Academy?"

Both of them hurriedly shook their heads, Lu Yun looked at Qingshan, and Qingshan pointed to the dual disciple of the Shanhe Realm: "He's lying!"

Without saying a word, the Xuanyuan Sword swept over and killed him directly.

Another disciple's body trembled: "I really didn't participate in the affairs of the Immortal Dao Academy."

Aoyama nodded: "He didn't lie!"

In fact, this is a very simple way of polygraphing, which is judged by the original spirit.

If you lie, the original god will fluctuate instantly, and if you don't lie, the original god will be very calm.

Of course, this method can't be done 100 percent, but it is still very accurate for low-level monks.

Since he killed the people of the Changbai Sect in Sun Moon City, and learned that the younger sister and the eldest sister were fine, the resentment in Lu Yun's heart had disappeared a lot.

It is impossible for the disciples of the Changbai Sect to all take action against the Immortal Dao Academy, only a small number of them participated, if they really killed them all without asking about it, Lu Yun himself would not be happy.

Moreover, the heavier the killing caused, the more it would affect his cultivation in the future, so he only killed the relevant people now.

This is also what Qingshan and Wu De mean, they don't want Lu Yun to become a murderer.

Lu Yun looked at the disciple, "What's your name?"

This disciple knew his own situation, and hurriedly replied: "Junior Xia Liangfei, I have seen three seniors."

The three of them looked at each other, this disciple was in his twenties, and he actually called them seniors.

Lu Yun coughed dryly: "How much do you know about the affairs of the Sun Moon City Immortal Dao Academy?"

He wanted to know who was involved in the first place through this person, so that he could take revenge.

Xia Liangfei didn't dare to slack off, and immediately told what he knew.

At the beginning, the matter of the Immortal Dao Academy also caused waves within the Changbai Sect, and it was mainly divided into three opinions.

The first is a wave of people led by the Supreme Elder Wang Dongyuan, who believes that the majesty of the Changbai Sect is inviolable, and advocates the destruction of the Immortal Dao Academy.

The second is the Taishang Elder Song Chang, who thinks that making a big fuss should not be so strong.

The last one is a wave of people such as Elder Taishang Cao Qingfeng, who have a careless attitude.

This is also the idea of most of the disciples of the Changbai Sect, after all, it has nothing to do with them, and they don't want to get involved in this matter.

Including the head of the family and the head of the previous generation, they all have nothing to do with themselves, and they are dedicated to cultivation.

The reason why Taishang Elder Wang Dongyuan was able to make a move was because he had the support of the deputy head Hou Yuan Fei behind him.

In the end, only Wang Dongyuan's descendants made a move against the Immortal Dao Academy, and most of the disciples of the Changbai Sect did not participate.

Lu Yun understood that Wang Dongyuan should be the Supreme Elder they had killed in Sun Moon City.

He glanced at Xia Liangfei: "Who was involved in this matter in Changbai Sect at that time?"

Xia Liangfei thought for a while: "There weren't many people who came to Sun Moon City to participate in this matter, most of them were stationed in Sun Moon City, and there weren't many left in Changbai Sect."

Aoyama nodded: "He didn't lie."

Lu Yun nodded: "Draw all the disciples of the Changbai Sect who are involved in this matter for me."

Xia Liangfei hesitated: "This ......"

Wu De put the long sword on his neck: "Do you want to draw or not?"

Xia Liangfei nodded hurriedly: "I paint, I paint."

Xia Liangfei drew a total of fifteen pictures, and after the drawings were finished, Lu Yun picked up the drawing paper and looked at it.

There are ten paintings, which are the ten people that Lu Yun killed in Sun Moon City, and two are the two disciples they killed on the way.

There is also a picture of the disciple who has just been killed, and there are only two people left who have not been killed.

One is Hou Yuanfei, the deputy head of Changbai Sect, and the other is a woman, Lu Rui, who captured the two of her little sister Lu Qiaoer.

Now there are two problems, one is how to infiltrate the Changbai Sect and rescue the younger sister and the eldest sister, and the other is how to kill the deputy head of the Changbai Sect and Lu Rui to take revenge.

Both of these questions are difficult, and it is more difficult for the first one to sneak in silently and rescue the little sister.

And once they are found to be encircled, they will face a life-and-death crisis, and this is only a chance.

The second one is not easy, Lu Rui is not afraid, it is just that the mountains and rivers realm is threefold, but Hou Yuanfei is more troublesome, and the strength of the mountains and rivers realm is sixfold, which makes Lu Yun feel pressure.

Of course, if he can use holy soldiers, he can fight against them, but it is difficult to kill them.

If you want to use the Holy Soldier, you must not be above board, otherwise once the Holy Soldier is exposed, he will be very dangerous.

Lu Yun fell into deep thought, Wu De and Qingshan were also very worried, the mountains and rivers were sixfold, and they couldn't fight against each other at all now.
