If I ask you to go undercover in the Hehuan Sect, will you go?

What Xue Yangyang made was not a magic circle, but a magic tool to activate the magic circle, which was a soul flag shining with black light.

Xue Yangyang named it the Black Soul Banner, which is concise and to the point.

This soul flag needs to be activated by spiritual power. The more spiritual power added to it, the stronger the power that bursts out.

The Black Soul Banner will create a magic array similar to the Blood Soul Heaven-Slaying Array, which can trap three to five people in the array and seal most of their cultivation.

The magic circle has two centers. The first one is the person holding the black soul flag. He is responsible for adding spiritual power to the magic circle and is the core of the entire magic circle.

The other one is used to add soul power, which can be removed or replaced by other magic tools. If the array eye that adds soul power is removed, the duration of the array will be greatly shortened.

This means that the Black Soul Banner must be cast by Lu Chen and Lin Cairan at this stage.

Why do they need two people to work together? Because none of the existing materials in Wanhua Valley can bear such a strong soul power at one time.

In order to seal the cultivation of the cultivator in the God Transformation Stage, Lin Cairan could only use soul magic to strengthen the formation.

There are flaws, but it's not a big problem.

After all, the materials were limited, and Xue Yangyang only spent one day.

Lu Chen was very satisfied: "Yangyang, Master really didn't misjudge you. Whatever reward you want, Master will satisfy you."

"As long as Master can spend more time practicing with me, I will be satisfied."

Xue Yangyang was extremely eager to ascend to the early Nascent Soul stage immediately.

Nascent Soul cultivators can not only improve their cultivation, but more importantly, they can condense their Nascent Soul.

Taoists call the physical body the turbid one and the primordial infant the pure one, or they call the physical body a fake person and the primordial infant a real person.

Simply put, the Nascent Soul is a higher being than the physical body and is an extra life. The higher you cultivate, the more clones you can create, and the more lives you have.

Even though Xue Yangyang had a powerful master, she still tried her best to save her own life.

After all, the master is too strong, and the enemies he encounters are all strong. If I want to stay by the master's side, how can I do that without working hard to improve my own cultivation?

Lu Chen suddenly remembered the Three Fires Burning Heart: "Yes, Master almost forgot that Master has another powerful treasure. This treasure can increase your cultivation speed by twenty times."

"Twenty times!! Thank you, Master!"

Lu Chen took Xue Yangyang and Dugu Ling to the secret room.

"By the way, let Elder Dugu teach you the dual cultivation technique. You must study hard. If you can find a way to increase the speed of practicing the dual cultivation technique, Master will give you another big prize!"

"Yes, disciple obeys your command!!"

Lu Chen kept it a secret, wanting to see if Xue Yangyang had any talent in making pills.

Lu Chen first asked Dugu Ling to test Xue Yangyang's physique. She was indeed not suitable for practicing Hunyuan Xuannv Gong, so she could only practice Yin Yang Harmony Gong, which was to replenish Yin with Yang.

With Xue Yangyang's physique and a body tempered by Lu Chen's Demonic Dragon God-Slaying Art, Xue Yangyang would not be able to exhaust all the energy even if she did it non-stop for 24 hours.

Not only is the total amount large, the recovery speed also far exceeds Xue Yangyang's speed of replenishing energy.

Dugu Ling personally taught Xue Yangyang the martial arts.

Lu Chen acted as an experimental subject and let the two men manipulate him.

Dugu Ling knew that Lu Chen liked this disciple, so she spared no effort to teach her many fox charm techniques.

Xue Yangyang studied very seriously, and in four hours, she had mastered all the key points of the technique.

In actual combat, when the Three Fires Burning the Heart entered her body, Xue Yangyang opened her mouth in shock.

"What is this??? It's too powerful!!! Master, I can't take it anymore, I can't take it anymore, you are too powerful!!!"

"Practice your skills and see how much you can improve?"

“I’m going straight up to the ninth heaven!!!”

Xue Yangyang only lasted ten seconds before collapsing to the side, her body twitching.

"What's up with her?"

Lu Chen looked at Dugu Ling in confusion.

"The Sect Master is too strong, she can't bear it. And..." Dugu Ling used the Soul Devouring Art, "Thirty times!!!"

"You mean, Sanhuo Fenxin has grown up again?? Hahaha!!"

Lu Chen laughed heartily.

That’s right, very reasonable.

Jindan stage, ten times.

When it reaches the Nascent Soul Stage, the Three Fires Burning the Heart is advanced to twenty times.

When one reaches the Spirit Transformation Stage, one will naturally advance another thirty times.

Next, the fusion and refining of the void, wouldn’t it be at least fifty times!!!

When we go to the spirit world, we must drive those ancestors completely crazy!!

Just as Lu Chen was madly looking forward to a bright future, Wanhua Valley suddenly shook violently, and a series of huge rumbling sounds were heard outside.

Then Lu Yourui ran over anxiously and shouted, "Brother Lu, it's bad! Many people have come from outside the valley, and there are also many huge flying monsters. Elder Wang has already activated the sect protection formation, and they are now non-stop attacking the Wanhua Valley!!"

"Humph!" Lu Chen snorted disdainfully, "You guys came just in time. I was waiting for you."

You don't even have to think about it to know who it is.

It must be Xu Bin and Yun Qiaoer who have been standing by, hoping to "take advantage of the conflict between the two parties".

Lu Chen took the Black Soul Banner and came to the entrance of Wanhua Valley with his disciples.

Sure enough, it was Xu Bin and the others.

Next to Xu Bin, there was not only Yun Qiaoer standing there, but also many disciples from other demonic sects.

The numerous monster beasts, the Wind Falcons, above them were even more eye-catching. Each one was as huge as a tall building, and was flapping its wings, creating hurricanes and attacking the protective formation of the Hehuan Sect.

Behind dozens of large-scale gale falcons there is an even taller beast, showing the demeanor of a king. It should be the gale falcon king.

Lu Chen did not bring Yun Xingyu out and asked Shen Hongwei to look after her.

Lu Chen had already used the Goddess' Soul-Falling Technique on Yun Xingyu, but the speed was not that fast.

Judging from the progress of the Fallen Soul Orb, it will take at least half a month.

The Goddess' Soul-Falling Technique will not change the mind of the person who is under the spell, but will only change her impression of Lu Chen and make her completely loyal to Lu Chen in the end.

As a mount, Yun Xingyu naturally needs to be absolutely loyal and no accidents can happen.

Lu Chen didn't want Yun Xingyu to have any negative emotions, so he simply didn't let her know.

"Lu Chen!!! Hahaha, your death is coming!!! You didn't expect that I would be back again. This time I have joined forces with the Falcon Clan, the Heavenly Corpse Sect, the Ten Thousand Poison Valley, and the Demon Control Sect. This time I will make sure you can't escape even if you have wings."

Lu Chen took a quick glance and saw that the Kuangfeng Falcon clan had sent out almost all its main forces, while the Tianshi Sect, Wandu Valley, and Yuyao Sect had only sent out a portion of their elite troops.

Adding everything together, that's the situation. There are only two people who can feel the aura of the Spiritual Transformation.

They definitely didn't know about their own changes and thought that there was only one Wang Yingfei in the early stage of Spirit Transformation who could fight in Wanhua Valley.

Then give them a little shock, use their soul-sacrificing banners, and start your own legend as the Great Demon King of the Dragon Spirit Continent.

Lu Chen ordered the other disciples not to move, and asked Concubine Wang Ying to protect them at all times. He led Lin Cairan out of the valley with extremely domineering steps.

However, he almost stepped into empty space in the first step, creating a gap in space.

"How can it be!!!"

Xu Bin and Yun Qiaoer looked at each other, their minds filled with turbulent thoughts.
