The Mortal's Path to Immortality

Spiritual Beast Sect.

Spirit Peak of the Refining Institute.

Cao Rui sat opposite Wu Qingxuan.

“I haven’t seen you for two years. You have successfully established your foundation. Not bad.”

“How many days will you stay in the Refining Institute this time?”

“Where do you plan to start?”

Cao Rui reviewed his previous achievements.

Basic Refining Technique (Level 0), Great Success.

Familiar with more than 20 Level 0 magic arrays.

Level 0 magic array engraving, Master.

After the foundation-building period, the spiritual consciousness increases greatly. The refiner can start to learn the first-level magic array. In the late stage of foundation-building, he can even start to contact the second-level magic array.

Cao Rui has also come into contact with the first-level magic array.

Cao Rui’s experience in alchemy is that the 0-level foundation is also very important.

The knowledge of spiritual pills in the 0-level foundation has laid a foundation for Cao Rui and is an important source of knowledge for Cao Rui to develop new pills.

If you want to make innovations in the art of refining, you can't just deal with the 0th level foundation of the refining array.

Cao Rui decided to take care of the 0th level foundation while learning the first-level array with Wu Qingxuan.

After Wu Qingxuan figured out Cao Rui's intentions, he decided to take a few hours a day to teach Cao Rui the first-level array.

The rest of the time, Cao Rui learned to engrave the 0th level array on his own.

Of course, the Spirit Beast Sect didn't have so many magic weapons to refine.

But Wu Qingxuan had a way. He had a special "metal plate" for practicing engraving arrays.

This metal plate was made by Wu Qingxuan himself. It was a kind of alloy. It was cheap and could withstand the engraving of the array, but it couldn't exert the power of the array.

It was perfect for learning.

For Cao Rui, after discovering that engraving the array on this metal plate and engraving the 0th level array with experience beads could also increase the experience beads, he decided to use this metal plate to accumulate experience in the future.

On this day, Wu Qingxuan was in the exclusive refining room.

Wu Qingxuan was explaining the knowledge of the first-level magic array to Cao Rui.

"Compared with the 0-level magic array, the first-level magic array is only half the size, but the difficulty is more than ten times higher. Without the powerful spiritual sense of the foundation-building period, the Qi-refining period will never be able to master it like mastering some first-level spells."

"I will first teach you the simplest first-level magic array, the first-level [ventilation]."

Cao Rui took the metal plate and began to engrave it with Wu Qingxuan.

Compared with the 0-level [ventilation], the first-level [ventilation] is nearly half the size, but the smaller volume carries more than twice the engraving lines.

Some subtle lines even need to be detected with spiritual sense, and cannot be seen with the naked eye.

Although Cao Rui has been following Wu Qingxuan's steps, and Wu Qingxuan deliberately slowed down the engraving speed to facilitate Cao Rui's learning, even so, Cao Rui still inevitably made mistakes.

In the end, Wu Qingxuan succeeded in engraving, and Cao Rui directly threw the metal plate into the smelting pool to re-melt and eliminate the magic array and save it for the next practice.

The first-level magic array is really not so easy to engrave.

"Hmm? Experience beads?" Cao Rui's heart moved.

Cao Rui suddenly found that the first-level magic array [Ventilation] experience beads appeared in his mind.

The first-level magic array no longer appears in a unified '0-level magic array engraving' style like the 0-level magic array engraving.

The 1-level magic array is more complex than the 0-level basic magic array, and a single experience bead is condensed in Cao Rui's mind.

This further shows that the 1-level magic array is much more difficult than the 0-level magic array.

For ordinary cultivators, each 1st-level array is extremely unique, and it takes more time to master it.

Cao Rui's heart moved: "Master Wu, how many 1st-level arrays have you mastered?"

Wu Qingxuan smiled slightly: "Yes, you have discovered the difficulty of 1st-level arrays."

"In fact, because arrays become more and more difficult to master as their levels increase, the refiners will have no choice but to concentrate their learning arrays on a single digit in the end."

"I currently have five 1st-level arrays that I have fully mastered, but there are only two 2nd-level arrays left."

"If you don't like the five 1st-level arrays I have mastered, forget it... Come with me."

Wu Qingxuan suddenly stood up. Although Cao Rui didn't understand why, he still stood up and followed.

Wu Qingxuan took Cao Rui to the depths of the Refining Institute.

In an unnamed hall, there is a downward passage.

After walking down the passage for a long time, a secret room surrounded by a simple warning array appeared.

Wu Qingxuan opened the secret room and took Cao Rui into it.

Cao Ru walked into the secret room and looked around slightly, with surprise flashing in his eyes.

The underground secret room here is more than ten meters high, and the room is brightly lit with light.

The most conspicuous thing is the pattern of magic array symbols that have been magnified several times on the wall.

It roughly evenly occupies half of the wall, and there is still a large blank space on the wall.

Wu Qingxuan said: "There are a total of sixteen first-level magic arrays, nine second-level magic arrays, and three third-level magic arrays."

"This is the number of magic arrays passed down from generation to generation in my Spirit Beast Sect."

"Each magic array was carefully carved on the wall by the first master refiner in the sect and passed down. This room is also the inheritance room of our Refining Academy."

"If you learn a new magic array in the future, don't forget to leave your mark in the inheritance object."

Cao Rui nodded vigorously: "Can I retreat here for a while and choose to learn a magic array?"

Wu Qingxuan gave a positive answer: "Of course, but if you want to learn the magic circle that I don't know, without my guidance, the learning difficulty will be greatly increased, so you have to be mentally prepared."

"I understand." Cao Rui nodded in agreement, thinking that he had experience beads, so the learning difficulty was not much different.

Cao Rui decided to condense the sixteen first-level magic circle experience beads in one breath, and then slowly selected the first-level magic circle for specialized practice based on his own needs.

When Wu Qingxuan saw that Cao Rui wanted to stay here to study the magic circle, he took the initiative to leave and gave Cao Rui time to study.

After Wu Qingxuan left, Cao Rui first read the names of the first-order formations on the wall.

Next to the formation symbol 뀗, there are notes on the name and efficacy of the formation 놅.

Cao Rui quickly found the formation talisman he wanted [Far Transmission].

The first-level magic circle [Remote Transmission] can transmit information over long distances.

Most defensive formations require carvings of formations to arrange microphones.

Just using the first-level magic circle [Far Transmission] to deploy the communication software is at least a first-level magic weapon, and the cost is too high.

In the level 0 magic circle, there is also a magic circle with a similar function [sound transmission].

[Far EasTone] is actually an advanced version of [Sound Transmission].

The distance of [Far Transmission] is about 10-100 miles, and the distance of [Sound Transmission] is only a hundred meters to a thousand meters.

Cao Rui's idea was to use a first-order magic array [remote transmission] to arrange equipment similar to modern signal towers.

Then use the low-cost 0-level magic array [Sound Transmission] to refine the 0-level magic weapon-level communication equipment and sell it to the majority of casual cultivators.

The entire southwest of Yunzhou is about 10,000 miles in length and width, and is about the size of three Huaxia countries.

It will be difficult for the signal tower to spread to the entire southwest, unless Cao Rui can develop the second-level [Far Transmission].

However, it is still extremely easy for Cao Rui to establish a communication area centered on Qinglingfang and deploy signal areas in some important locations.

For example, to set up a signal area across southwest Yunzhou, only about a hundred signal towers need to be deployed.
