In the blink of an eye, a month has passed.

Chen Xiaoming was notified not long ago that he could leave Yangcheng.

However, he applied for Chen Changqing's brothers and sisters to continue to stay, and wrote a letter back to Beihai Town to clarify some of the situation in Yangcheng.

And Chen Changqing has changed from two points and one line to three points and two lines. The mansion, the study, the entrance of the school. Occasionally, I will go to the National Teacher's Mansion to see if Cai Yong has returned.

It's a pity that Cai Yong still hasn't returned.

The more this was the case, the more Chen Changqing felt that the task assigned to him by Zhuge Yangtian was not simple.

It's a pity that he has no chance to give up now, so he can only prepare more in the event of an event.

As for Chen Ziying's demon eradication task, the system has clearly given the task.

Mission: My sister wants to get rid of the demon!

Mission Objective: Secretly accompany Chen Ziying to participate in the demon eradication mission, and cannot be discovered by her.

Reward: Nine Heavens Golden Pill.

However, no matter whether the system gives a task or not, Chen Changqing will definitely follow secretly this time.

In order to confirm where his sister went to get rid of the demon, Chen Changqing drew a lot of spiritual smoke spells and sent them to the old Bai senior. In the words of Senior Bai, Chen Changqing had already guessed the destination of this demon eradication mission.

It was a demon cave located in the southeast of Yang Jingguo-Black Crow Ridge.

Black Crow Ridge is very famous in Yangjing country.

Because of its spatial characteristics.

Black Crow Ridge is a suspended sky fortress, and the person who guards Black Crow Ridge is a demon king in the middle of the Spirit Sea Realm. It is said that it used to be a certain immortal beast, and after the immortal failed to cross the Golden Immortal Tribulation, it regained its freedom, and relied on a space magic weapon of its previous owner to change the characteristics of Black Crow Ridge, making the entire mountain fly, and has the ability to escape in the void.

It is precisely because of this ability of the Void Escape that several cultivators' encirclement of the Black Crow Ridge has ended in failure, and every time it is encircled, as long as the Black Crow Demon King feels that it can't be defeated, he will escape into the Void before the other party forms an encirclement, and travel to other places.

This time, Lin Qingqing got a magic weapon of space by chance, which can track Black Crow Ridge and seal the space for a short time.

So, Lin Qingqing decided to start this mission to eliminate demons.

After learning about this demon eradication task, Chen Changqing felt that although it was difficult to complete this task, the danger might not be dangerous.

The combat power of Black Crow Ridge has already been explored. A demon king in the middle of the Spirit Sea Realm, and three demon generals in the middle of the Spirit Lake Realm. The others may be dozens of demon soldiers in the Spirit Spring Realm, as well as hundreds of little demons in the Spirit Well Realm.

The demon king of Black Crow Ridge is known for bullying the soft and fearing the hard, and he really can't beat it and escapes.

I haven't heard of how many cultivators they have killed and injured.

It's just that Chen Changqing speculated so, but what it actually was, he didn't dare to assert.

Anyway, when the time comes, follow the past and make plans according to the situation.

Recently, Chen Changqing has been researching some new spells, in addition to drawing an upgraded version of the Thunder Fire Spell, the Nine Heavens Thunder Fire Spell, as the main means of attack, he has also successfully drawn a very practical stealth spell called the Latent Shadow Spell.

The Shulker Spell is a technique developed based on the Shadow Escape Technique, which can travel through the reflection of all things in the world as a bridge, and it also has the property of hiding spiritual power fluctuations, so it is not easy for people to detect.

The only drawback, the huge cost, and the fact that some spells and spells cannot be used during the shulker.

The problem of huge consumption is not a problem for Chen Changqing now. He also had twelve Spirit Sea Realm spirit stones and three Spirit Lake Realm spirit stones on his body.

This stock is leveraged.

As for spells that can't be used during the lurking period, most of them are offensive spells. Most of the protection and support spells can be used.

Chen Changqing made some attempts in the eight-sided exquisite tower, and then decided what clothes to wear and what charms to bring this time.

The new clothes have already been made by Chen Changqing.

Chen Ziying has one, and he has one for himself.

The material of the garment is stronger and less susceptible to damage. The above spells are slightly adjusted, and they are all based on general basic spells.

Since the main opponent of this demon removal mission is a monster, not an evil demon, so I have to make some additional preparations.

So, a few days before the start of the demon eradication mission, Chen Changqing also chose to retreat to prepare, and he didn't even go to the study.

......

Finally, the day has come to exorcise demons.

This time, the demon slaying group of the academy was led by two mentors, Lin Qingqing in the late stage of the Linghai Realm, and Zhang Tieshan in the middle of the Linghai Realm.

There were a total of ten members of the Demon Slaying Group, eight of whom were students of the Spirit Lake Realm, and two were students of the Spirit Spring Realm.

Because the distance was quite long, this group chose to fly in the sky at the beginning, and the two cultivators of the Spirit Spring Realm were led by two instructors.

And as the only hidden supernumerary of the Demon Eradication Group this time.

Chen Changqing was also ready to set off early, disguised, masked, and brought all the equipment, elixirs, and charms. Then let's go!

The clouds and shadows in the sky are stacked, and you can also cast a shulker spell.

So, Chen Changqing hid his figure like this, and followed the group not far away.

In this way, the sky flew for almost a day before the school demon slayer stopped to rest.

And Chen Changqing finally got a chance to breathe.

He really didn't dare to get too close, after all, Lin Qingqing was a rare master, and he was afraid that he would be discovered by the other party if he was not careful.

The group has set up several tents in a clearing, and it is estimated that they will rest here tonight.

To the southeast of Yang Jingguo are patches of woods.

There are so many glades like this.

Lin Qingqing and that Zhang Tieshan took turns to keep vigil, while the other students rested with peace of mind.

Chen Changqing hid his figure and took a break.

Nothing was said all night.

The next day the team set off again.

This was repeated for five days, and there were no accidents except for the occasional attack group of demons with long eyes.

Five days later, the group finally arrived at their destination.

It is an uninhabited mountain range called the Sunset Mountains.

It is said that in ancient times, this was the place where the immortals and demons fought each other.

After the war, the perennial evil aura here has been condensed all year round, and except for a few monsters that can survive here, there are no living creatures in this vicinity at all.

The people of the demon slayer group are here, so they naturally need to use spiritual energy to protect their bodies, otherwise they will be injured by evil qi.

Of course, Chen Changqing is no exception.

But he wondered a little in his heart, why was this Black Crow Ridge hidden here?

Chen Changqing didn't have a magic weapon for space exploration, all of which could only be confirmed when Lin Qing found out where Black Crow Ridge was.

And after entering this Sunset Mountain Range, after the Academy Demon Slayer entered the Sunset Mountain Range, everyone became cautious.

Lin Qing lightly held a uniquely shaped compass in his hand, and probed around, all the way deep into the mountains.

On the third day after entering the mountains.

Lin Qingqing suddenly made a move and killed a three-eyed crow hiding in the shadows.

This three-eyed crow is the feather incarnation of the Black Crow Demon King, specially used to monitor the environment and inspect the enemy.

The presence of a three-eyed crow here means that this Crow Ridge is likely to be nearby.

After confirming this, Lin Qingqing took out the compass again very decisively, and the compass opened from the middle, and a treasure map flew out of it.

As soon as she raised her hand, the treasure map flew into the sky, turning into a canopy, and in an instant, most of the area of the Sunset Mountain Range was enveloped.

Chen Changqing looked up at the sky and frowned slightly.

Under the cover of this treasure map, it should not even be used to cross the void talisman.

At this moment, a shrill voice actually came from the Sunset Mountain Range: "Why did Daoyou rush to kill them all!"

Needless to say, the owner of this voice must be the Black Crow Demon King.

Lin Qingqing didn't answer the words of the demon king, but just glanced at Zhang Tieshan, and the two of them led the others towards the depths of the southern mountain range.

Chen Changqing followed, and after a while, they could all see that in the middle of the Southern Mountain Range, there was a mountain ridge spit out in a strange shape.

That's Crow Ridge?

Above the mountain, a fortress is faintly visible. There are formation patterns faintly emerging on the fortress, and you can also see faintly arrow towers and rune tower-like buildings.

Black crows hovered over the tower, babbling and chirping.

This kind of scene looks very weird.

The atmosphere of the demon slayer also became solemn as a result.

"Wait for the ten of you to attack with Master Zhang. Lin Qing said lightly.

Then she suddenly jumped to her feet, turned into a firebird, and flew up the mountain.

Again.

Chen Changqing frowned when he saw it.

It seems that the indomitable fighting style should be a tradition passed down from ancestors.

At the moment when the firebird took off, on the Black Crow Ridge, little crows flew out, and countless little crows gathered out, turning into a middle-aged man wearing a black robe and a hood.

"Crow, you can't escape this time. The firebird turned into a human, and Lin Qing whipped lightly and hit the black-robed man.

"Fire lady, why do you want to kill them all?"

As he spoke, the black crow flew away, and Lin Qing lightly whipped him into the air.

No, there is no short!

The whip struck the air, and a burst of sparks scattered, and seven or eight little crows were burned to ashes by the flames in an instant.

"Kill them all, when you killed my little junior sister three years ago, how could you ever think of letting her go?"

"In that case, it seems that there is only one war today. ”

As he spoke, the crow roared in the sky.

In the dense forest, countless little demons suddenly rushed out, and in just an instant, they surrounded the demon slaying group on the ground.

Zhang Tieshan was not in a hurry, and shouted: "Formation!"

Zhang Tieshan was in this academy, and he was originally the instructor of the group attack array.

For this demon eradication mission, he had started to practice the battle formation with the ten students in front of him a month ago.

Under Zhang Tieshan's order, the eight Linghu Realm students stood in the direction of the gossip, while the two Lingquan Realm stood in the middle of the formation, acting as the eyes of the formation.

Chen Ziying stood in the position of the eye of the formation, ready to go.

She had already experienced a similar battle the last time she was in Zhu Village, but she didn't seem overly nervous. On the contrary, Lin Baosheng, the spiritual spring realm cultivator standing beside her, turned a little pale. It was the first time he had experienced this type of battle.

"Brother Lin, don't worry, we have two Spirit Sea Realms. "At the moment of the war, Chen Ziying, a little girl, still has time to act as a life coach to comfort the friends around her.
