Under the base of the Xuanwu Heavenly Pole Pivot Array was a huge pillar of Xuaniron.

Charlotte knew that the material of this formation base was able to resist the attack of the fifth-level demon pill cultivator.

At this moment, the closer Charlotte got to the bottom of the formation base, the stronger the attack energy emanating from the Xuantie pillar.

Mental perception was released, and Charlotte felt that there was obviously a hole the size of a wine glass at the bottom of the formation base, and the white formation base energy was slowly leaking outward.

There is an essential difference between self-contained energy and injected energy.

After the formation of the formation, the formation base material will stimulate the innate attack energy, set the range, the closer the distance, the greater the energy excitation.

But the injection of energy is to ensure the operation of the formation.

The two are different, but they are related.

The injected energy is like an acquired cultivation, and the attack energy that comes with it is like an innate endowment.

The higher the quality of the array base material, the stronger the innate energy.

Charlotte's current attack is this innate energy.

The cost of this attack is small, but the cost of the vulnerability is large.

With the energy infused and the innate energy.

"No wonder Yu Changqing is tired of becoming a dog, and the formation repair has not been completed, it turns out that there is a problem with the formation base. ”

Charlotte secretly said while releasing the mental shield to resist the automatic attack energy of the formation.

In a few moments, Charlotte was at the bottom of the Pillar of Darksteel.

Pull out a large pile of the best ores from the storage space, which were brought from the mortal world.

It wasn't used until then.

After the solar fire was calcined and melted, the hole was quickly patched.

But after a closer inspection, Charlotte found that there were still wisps of energy quietly leaking out.

The mental perception was exerted to the extreme again, only to find that there was a black trace at the loophole.

"What a strong divine soul knife cut~"

When Charlotte saw this black trace, she guessed that it should be the mysterious energy stimulated by the Nine Demon Clan's Burning Heart and many masters.

"You can actually attack the Formation Base Dark Iron Pillar from underground!"

Charlotte understands why the demon clan is desperately attacking Changjin Palace, as long as they occupy Changjin Palace, they can break the Guardian Array at the base magic circle of the surface formation.

Then pull out the Xuanwu Heavenly Pole's formation base Xuantie Pillar.

Charlotte now doesn't know how many Xuantie Pillars there are in Changjin Palace, but the Xuanwu Heavenly Pole should be the most critical place.

"According to the current ability of the demon clan, this step should be their ultimate. ”

Charlotte also secretly admired the perseverance and determination of the Nine Demon Clan.

"How did they trigger that huge, mysterious energy attack?"

"It was actually able to damage the Xuantie Pillar of the main formation of Changjin Palace?"

The Heart Sword World was unleashed, enveloping the damaged part of the Darkiron Pillar, although the formation attack continued, Charlotte's mental energy was very huge.

"If the traces of this divine soul knife cut are removed, the foundation of the formation will not be stable, and the energy will not be filled. ”

The milky white mental energy was injected into the iron pillar, and sure enough, the black marks began to fade gradually.

At this moment, Charlotte suddenly heard a sharp whistling sound in her ears.

It came from deep underground, and it seemed to come from a different time and space.

But Charlotte felt a kind of anger and despair, a kind of unwillingness.

Finally repaired the loophole of the Xuantie Pillar of the Changjin Palace Formation, Charlotte broke through the ground, the Heart Sword World was very sharp, and the deep soil layer was difficult to resist.

Flashing out of the Heart Sword World, Charlotte wiped the sweat from his forehead, took a breath, and looked up, only to see the old master, Yu Changqing, King Wei and others all looking at him in amazement.

"Why do you think of me like that?"

Charlotte was stunned.

"You're not dead?"

The old master asked.

"Hey, there's something wrong with you, right?"

"Do you want me to die?"

"No, this, Xiao Xia Gongzi, I thought you would be injured by the formation energy attack. ”

The old master's tone was a little embarrassed.

"Yes, Young Master Xia, you may not understand the power of Changjin Palace's guardian array. ”

Yu Changqing continued.

"The power of the circle?"

Charlotte asked.

"Yes, the attacks issued by the formation on the surface need to be controlled by humans, but underground, the attack of the formation is automatic. ”

"When I saw you suddenly go down, I knew that something was wrong, so I hurriedly called my teacher. ”

"Xiao Xia Gongzi, you are too reckless, so reckless, what if there are three long and two short?"

King Wei stepped forward, his eyes full of worry.

"It's okay, I went down because the lower end of the iron pillar of the formation base was damaged by the attack of the demon clan, and the energy continued to leak out. ”

As soon as Charlotte finished talking about the situation, the old master immediately said:

"I said that it is so difficult for them to inject energy into the circle these days, so that's the case. ”

The old master suddenly realized, and immediately said gratefully:

"I'm sorry, Xiao Xia Gongzi, I won't rob you of this apprentice Xiao Danping, just let him follow you. ”

Charlotte glanced at the crowd and found that the little scholar was poking his little head out from behind the old master, looking at Charlotte's eyes full of admiration and admiration.

"You, come out. ”

Charlotte beckoned to the little scholar.

"Teacher Xia, I, I~"

"What do you say?"

"Would you like to come with me?"

"I do. ”

"Haha, okay, it's decided, don't regret it. ”

Charlotte knew that such a genius little guy had to be snatched first.

The old master looked at Xiao Danping with some pity and said:

"After following Teacher Xia, you must be diligent, if you don't understand, you have to ask, and you can't be smart. ”

Yu Changqing continued to charge the formation, and this time the formation energy storage was very smooth, and after half an hour, the energy of the guardian array was restored to fifty percent.

More than 10,000 scholars in the Changjin Palace began to concentrate on the recitation square to read aloud again, and a rising power of faith recitation was injected into the great array along the central spirit stone of the Xuanwu Heavenly Pole.

Suddenly, Charlotte felt an extra ring in her Heart Sword world.

The size is about the same as the Xuantie Pillar, floating in the Heart Sword World, and it looks very dignified.

"What is this?"

Charlotte looked closely, but could not tell what the ring was.

"Then test your might. ”

Charlotte knew that something in the Heart Sword World must have a big effect.

This ring is not ordinary at first glance, milky white, very holy, somewhat like the Confucian mana of Changjin Palace.

The heart sword was sacrificed, and the ring "swished" and quickly rotated, and a halo of energy enveloped the heart sword.

"Actually formed a column of energy?"

"What kind of skill is this?"

A thought passed, and Irina, the master controller in the Heart Sword World, immediately sent a message:

"Xuanwu Heavenly Polar Ring!"

"What, it actually rubbed the attack skill of the Changjin Palace Central Formation?"

Charlotte was speechless.

It seems that good things have not been done in vain~

"Rubbing!"

"It's really a bit against the sky. ”

Charlotte was a little happy.

This trip to Changjin Palace not only gained a highly talented disciple Danping, but also added a skill to the Heart Sword World.

"Bastard~"

"Damn Charlotte, I swear to the Nine Demon Ancestors that I will kill you!"

"How dare you corrupt the crack of the seal that we took a lot of effort to break!"

"It's a pity that thirty percent of the Nine Shadows Energy of the Demon Palace~"

Burning Heart spurted a mouthful of purple blood on the throne of the Demon Temple, and said hysterically.

"King, don't be angry, there is more than one seal in the human world, if it doesn't work here, let's go somewhere else, I don't believe that Charlotte can take care of it?"

The nine-headed bird demon beast next to the burning heart shook its head and said.

"You get out of here~"

"Do you think it's easy to break the seal elsewhere?"

"It took us a thousand years to find this opportunity, damn Charlotte, I have to kill you~"

The heart-rending sound echoed in the demon hall.

The nine-headed bird, one of the thirteen Taibao, waited for the burning heart to calm down and said:

"King, you don't have to worry, we have successfully captured a human child, hehehe~"

"What, the soul snatcher succeeded?"

Burning Heart Huo stood up from the throne, and the purple glow in his eyes was excited.
