But even if there is only the ninth layer, the entire Shu Mountain will not be shaken.

After all, the lock demon tower is very important, if it fails, what will he do to imprison the demon in Shushan.

There are even some Shushan disciples who are ready to roll up and leave.

If the Lock Demon Tower fails, and every layer runs into the aura, it will be a matter of time before the millions of demons inside run out.

Therefore, it is the best policy, and the disciples of Shushan are secretly planning one by one.

But because Xu Ye is still there, it is not easy to have seizures.

After all, that kind of thing hasn't happened yet, and it's stupid to leave without seeing the form clearly.

As a troublemaker, Cheng Haoxuan still didn't know it.

Xu Ye, Yin Changqing, Ye Wen and the others rushed to the Lock Demon Tower.

I saw Xu Ye looking at the wisps of beard of the Lock Demon Tower, and he didn't say anything.

In the end, he had no choice but to turn around and leave, telling the disciples to take care of it.

Because he couldn't help it, he could see that it was an internal problem.

But what if the lock demon tower is opened, and the demons take this opportunity to run out.

After all, no one knows what's going on in the Lock Demon Tower.

In the Lock Demon Tower, the fact that a large amount of aura had spilled into the ninth layer had of course also attracted the attention of the upper eight layers.

One by one, they had to run down to the ninth layer, but they hadn't absorbed the aura for a hundred years or a thousand years.

Now that he felt the existence of the aura, he ran to the ninth layer like crazy.

Cheng Haoxuan had already considered this, so he laid a seven-grade Qiankun defense circle at the entrance of the ninth layer.

Even the full force of the Distraction Realm may not be able to break it.

Who let those demons bother him one by one before, his eyes were full of calculations.

It is impossible to rub the aura now, which leads to the overcrowding of the eighth layer of demons.

They were all crowded on the adjacent eighth floor, but fortunately, Peng Fei got some pills on the first floor and didn't come down.

And with this defensive formation, the demons in the ninth layer can rest assured that they can absorb the aura and cultivate.

The demons above the ninth floor can't break the formation, and it's difficult to break it, because Cheng Haoxuan has spread the formation eye in the adjacent nine layers and is not outside the door.

Unless the formation aura is hurried or the pattern is destroyed.

But there was this giant spirit gathering array in the ninth layer, and it was impossible to consume the Qiankun defense array without spiritual energy.

Don't even think about destroying the lines or something, Cheng Haoxuan painted it in the same way.

This formation can be almost seamless, unless the demon of the ninth layer wants to go to the upper eight layers and destroy the formation eye.

It is impossible for the Lock Demon Tower to teleport the demons that have broken through to the ninth layer.

This is all blocked by the Qiankun Defense Array, and the teleportation will only teleport to the door.

To sum up, Cheng Haoxuan took out two spirit stones to make a spirit gathering array, and the effect was still very good.

Although the only two spirit stones left on his body are gone, it is still worth it to harvest the return of these thousand demons.

After arranging the Spirit Gathering Array, Cheng Haoxuan began to refine his Seven-Rank Pill.

Anyway, the ten plants that the old goat gave were almost enough.

Moreover, it is useless to keep the seven-grade elixir, if you want to refine the seven-grade elixir, you have to use the seven-grade elixir to pile up the alchemy attainments to the seven-grade.

After the first furnace, Cheng Haoxuan spent more than two hours, and spent some mental energy to make himself sweat profusely.

The formation was full of dregs, Cheng Haoxuan shook his head helplessly and smiled bitterly.

The first time he refined the seven-rank pill, and he was just familiar with the six-rank pill, he didn't have much hope of refining it, and Haoxuan didn't report much hope.

The residue formed by these seven-grade elixirs was mixed with the six-grade elixir, and the six-grade elixir was repackaged and refined into a six-grade elixir and handed it to Hei.

After recovering his mental strength, Cheng Haoxuan began to refine the Seven Rank Pill for the second time.

If he fails, he estimates that he will have to wait a few months before he can break through the seventh-grade alchemy attainment.

If it succeeds, it will naturally be better, and if it succeeds, it means that Cheng Haoxuan is one step closer to saving his parents.

Exhaled a breath, Cheng Haoxuan's eyes were firm, and the formation rose and the yang fire appeared.

Proceed with each step without any mistakes.

Finally, two hours later, Cheng Haoxuan used twenty strains of seven-rank elixir to refine a seven-rank elixir with slight impurities.

Putting away the formation and yang fire, Cheng Haoxuan looked at the slightly impurity of the seven-pin pill in his hand and shook his head helplessly.

Sure enough, I was in a hurry, although the refining was successful.

But one out of 20 plants is too large.

But fortunately, it's not still refined into one, and now the seven-grade elixir is gone.

There was no way, Cheng Haoxuan had to spend his time mastering the formation.

If the formation attainment reaches perfection, it may be helpful for alchemy, isn't it?

Spend the remaining two hours cultivating the formation.

Cheng Haoxuan successfully attained the formation of six grades below to reach the realm of perfection.

If the sleepless cultivation can't be reached, then Cheng Haoxuan is really in vain.

This is the seventh, it is the day when Cheng Haoxuan came out of the lock demon tower.

Cheng Haoxuan took out the moon shadow mirror and put the old goat into the moon shadow mirror Zheng

That's right, Cheng Haoxuan's method is to hide the old goat in the moon shadow mirror, and isolate the ban through the moon shadow mirror and take the old goat out.

I don't know if I'll be able to do it, but I always have to give it a try.

The thousands of demons on this ninth layer came to the door.

Of course, they didn't want to escape, but they wanted to send Cheng Haoxuan.

These are not less than Cheng Haoxuan's, a large number of elixir formations.

The spirit gathering array formed by those two lower-grade spirit stones alone was enough for them to use for half a year.

Cheng Haoxuan waved his hand and said: "There is no banquet that will not be dispersed, although we only know each other for a few days, and I haven't even known all of them, but since you trust me, I will definitely live up to your expectations, I am not here, you all have to cultivate well and can't fall behind, if someone bullies you, call me back, remember, you are very strong now, don't be afraid of the demons below the fifth layer, don't be afraid of them, don't embarrass me, okay, that's all, I'm leaving." ”

Turning around and touching Hei's head, Cheng Haoxuan took Hei's hand and left with a free and easy back.

As soon as the door opened, Cheng Haoxuan smiled and led Hei out of the Lock Demon Tower.

Ye Wen, Zhuge Yu and Qi Zhe smiled when they saw Cheng Haoxuan.

Cheng Haoxuan walked out and said with a smile: "Let everyone worry, I'm back." ”

"It's time to talk about the past, son, you lock the demon tower with me first, what happened to the demon tower was not done by you. Xu Ye squinted his eyes and stroked his beard and asked.

"That, didn't I just wake up and have no spiritual power, so I thought about setting up a spirit gathering array. Cheng Haoxuan smiled awkwardly and made excuses.

"Son, what level of attainment have you reached in the formation to be able to make such a powerful Spirit Gathering Array?" Xu Ye asked again.

"Ahem, Senior Xu, listen to me, it's really that the demons in the lock demon tower don't have long eyes, and they all want to eat me, if it weren't for the black, I would have been torn apart a long time ago, right? Cheng Haoxuan said embarrassedly, and then touched Hei and motioned to Hei to cater to him.

"Hmm...... Oh, yes. Hei was stunned, then nodded and lied with Cheng Haoxuan, if it weren't for the black and stunned Xu Ye, he would almost believe it.
