Chapter 78 A New Demon Army Is Coming!

Old Long stared at the manuscript in his hand. As he read deeper, his expression became more and more excited and shocked.

Lu Qing'an watched quietly, wondering if he had accidentally given the manuscript to Bai Lu for re-engraving. But then he thought, he couldn't make such a low-level mistake.

"The structure of this formation is really mysterious and unparalleled! But there are many places that I can't understand." Old Long frowned slightly, realizing that his attainments in formation were still insufficient.

Seeing this, Lu Qing'an was secretly satisfied.

It's right not to understand.

Only a genius can deduce the correct answer from a full of wrong information.

Even if he himself got this replica manuscript, he might not be able to understand it.

"Daoyou, I have something to ask you. Are you really a seventh-grade formation master?" Old Long put down the manuscript and stared at Lu Qing'an, obviously doubting what Bai Lu said. Bai Lu once said that Lu Qing'an was very likely a seventh-grade formation master, and this speculation was only because of Lu Qing'an's Liuli Realm cultivation. After all, a cultivator in the Glazed Realm can be a seventh-grade array master at most.

A strange look flashed across Lu Qing'an's face, and he knew that he was at most a third-grade array master.

"Not bad."

"Based on the array structure in your manuscript, your cultivation may limit your array grade, but your array attainments are far beyond mine. If you come to Void City in the future and want to be assessed and promoted to an eighth-grade array master, you can come to my guild to find me. Based on your attainments, I can exempt you from the assessment." Elder Long smiled, and his words were full of goodwill, obviously trying to recruit Lu Qing'an.

At the same time, he also made an application to make friends with Lu Qing'an.

Lu Qing'an didn't know what level of city Void City was, but he nodded.

That was a later story, anyway, he couldn't leave Panlong City in a short time.

If you are not strong enough, rashly going to those places where strong people gather is tantamount to asking for trouble.

"I have roughly browsed this manuscript. If you have any confusion, you may discuss it together and see if I can provide some insights." Elder Long also wanted to see what problems Lu Qing'an encountered.

Lu Qing'an must have no problem in the Demon Hunting Array, as the array has been arranged, but the other array he is currently studying does have some problems.

After pondering for a moment, Lu Qing'an decided to raise the problem he was currently facing. Anyway, Elder Long had mistakenly believed that he had encountered difficulties in the arrangement of the Demon Hunting Array, and the replica manuscript had been misleadingly modified by him, so it would be fine to take this opportunity to ask about other arrays.

"This Demon Hunting Array is composed of several wonderful small arrays. I have a problem with one of the arrays..."

Lu Qing'an talked about the theory of thermal expansion and contraction, and began to ask what kind of array pattern he needed to engrave in order to achieve the effect.

"Expansion due to heat and contraction due to cold? Daoist friend, I really don't understand the mystery. Can you explain it in detail?" Elder Long's eyes sparkled with excitement, and he looked eager to learn.

After listening to Lu Qing'an's so-called expansion due to heat and contraction due to cold, he found that he had some insights, but they were not thorough.

Lu Qing'an simply turned into a physics teacher and explained the theory in detail, hoping that Elder Long could understand the essence of it and give useful suggestions.

After listening, Elder Long fell into a long period of contemplation and comprehension.

Suddenly, he suddenly realized and exclaimed: "Daoist friend! Is this formation concept created by you?"

Lu Qing'an blinked and thought to himself that no one in this world should know this little knowledge of physics, so he nodded slightly.

"This is the so-called peerless genius!" Elder Long praised sincerely.

Lu Qing'an said calmly: "Old Long, you are too kind. I really don't deserve it."

Elder Long took a deep breath to calm down the excitement in his heart, and then gave Lu Qing'an some small suggestions. When Lu Qingan heard this, his eyes lit up.

This old man Long told him a few array patterns for him to refer to.

Lu Qingan nodded, and soon found that the array was about to end.

"Daoyou, this array is about to close. If you pass by Void City in the future, I hope to see you! I have gained a lot from talking about arrays with you this time!" Old Long smiled and bowed his hands to invite him, his words full of sincerity.

Lu Qingan also learned something from the conversation with this high-level array master, so he smiled and replied: "There will be a chance."

"Goodbye." Old Long smiled.

As the array stopped, the light and shadow of Old Long disappeared without a trace, and the door of the secret room opened immediately. The light from outside sprinkled in, and the room suddenly became bright.

Bai Lu saw Old Long's demeanor for the first time, and he was secretly amazed in his heart. When he looked at Lu Qingan again, his eyes had become different.

"Daoyou Jia is really hidden. It seems that your attainments in arrays are not limited to the eighth grade." Bai Lu sighed with a wry smile.

Lu Qingan responded calmly: "Old Long is just being polite, Daoist Bai, there is no need to be so."

"What did Daoist Fellow gain this time?" Bai Lu asked.

Lu Qingan nodded: "I have gained a little, but I need to work harder to successfully set up the Demon Hunting Array."

"Okay, I will contact Old Long more often. If I have any new gains, I will definitely inform you." Bai Lu smiled.

Lu Qingan nodded, and then left the Array Master Guild with Bai Lu and returned to the City Lord's Mansion.

After returning to his residence, he immediately began to study what he had just gained, and spread the array pattern mentioned by Old Long in front of him for careful study.

"They are all seventh-grade array patterns. With my current strength, it is difficult to depict them."

This consumed too much energy and immortal energy. Lu Qingan had to learn from his strengths and create an array pattern that suits the current situation.

So, he buried his head in the deduction of the formation, and two days passed in a blink of an eye.

It was just getting dark outside.

"It's done!" Looking at the formation pattern he created, although it was only of the third grade, it achieved the expected effect, Lu Qing'an couldn't help but smile.

"The next step is to assemble the formation and then arrange it. However, two more things are needed."

A ball of fairy fire of the seventh grade!

And a piece of extremely cold treasure!

For these two things, he could only go to the Alchemist Guild and Jubaozhai to check.

"Now Gong Chuhe and He Jingming should have left Panlong City, so we can only find Huang Zisheng and Liu Bude."

So, Lu Qing'an left the City Lord's Mansion and found the two people separately.

Both of them expressed helplessness about his needs. The highest-level fairy fire currently in the Alchemist Guild is only the fifth grade. The fairy fire of the seventh grade needs to be transferred from the headquarters, but the response from the headquarters is not good, especially in the Panlong City area.

As for the treasure with the power of extreme cold, Jubaozhai also has no inventory. Liu Budde said he would contact the headquarters to inquire.

However, Lu Qingan did not gain nothing this time. Liu Budde unexpectedly gave him a sum of immortal stones.

"The auction of the Linglong Tower that Daoyou sent to bid for ended, and I got an extra three million immortal stones."

Lu Qingan was a little surprised. From this point of view, the Linglong Tower was worth at least eight million immortal stones, and Jubaozhai had to make a profit, and it was probably auctioned for tens of millions of immortal stones.

His savings increased by another three million immortal stones, but although there were many immortal stones, they could not buy immortal medicine to increase his life span. The immortal medicine in Panlong City had been sold out.

"No, Bai Lu still has some."

Last time, he only cheated Bai Lu of immortal medicine worth three million immortal stones. It was expected that he still had immortal medicine of the same value, so he just bought them all.

So, he immediately contacted Bai Lu and made an appointment to meet in the reception hall.

At the same time, he also wanted to see if he could get the immortal fire and treasures with extreme cold properties that he urgently wanted from the Xianjian Sect.

At the same time, seven people flew out from deep underground in a secluded valley outside the city.

They were the remaining seven demons who came to Panlong City, led by the blood demon, Gu Tuotuo.

At this moment, he looked solemn, but with a little hope, looking into the distance.

Not long after, he saw a line of black shadows appearing in the distance, coming here at a very fast speed.

There were more than 30 demons in total!

The leading demon was his cousin, Gu Yuzhao!

He really had no choice but to ask for help from his cousin Gu Yuzhao, who had left the family and came to the human race to train, and to communicate with him to share the credit after releasing the demon dragon!
