The Mortal's Path to Immortality

In order to develop the Lingyin Jade Pendant as soon as possible.

Cao Rui entered the refining room and began to engrave the formation in seclusion.

In this way, more than 20 days later, with the engraving of the 0th level [Sound Transmission] on the metal plate, the experience beads engraved in Cao Rui's mind were finally filled with experience values.

The black experience beads have turned into purple beads flashing purple light.

Cao Rui clicked the experience beads with his mind: "Break it for me!!"

The purple experience value in the experience beads turned into a torrent that surged into Cao Rui's mind and limbs.

After a while, Cao Rui opened his eyes and absorbed the memories in his mind. Cao Rui has mastered all the basic ninety-nine and eleven 0th level array basic symbols.

The level of the 0th level array engraving has also broken through to the perfect realm.

Looking at the entire Xiuxian world, there are only a handful of refiners who can master all eleven 0th level arrays in the world.

In many places, some 0th level arrays have even been lost.

But Cao Rui relied on the experience beads to restore all eleven basic magic array symbols.

"Then I will refine the Lingyin Jade Pendant myself."

"Then try to see if [Sound Transmission] and [Shadow Transmission] can be engraved on your Lingyin Jade Pendant at the same time."

Cao Rui, who had just broken through, was full of energy and took out the refining furnace to start refining.

Cao Rui and Wu Qingxuan had discussed and formulated the materials of the Lingyin Jade Pendant many times before, and finally came up with a suitable plan.

This was the first time Cao Rui officially refined it.

Cao Rui took out some jade powder, Lingwen Xuanjing powder and other auxiliary materials according to the plan.

After putting them in the refining furnace, Cao Rui condensed his magic power and began to slowly liquefy and fuse them.

Cao Rui's basic refining technique has been perfected, and the fusion process is very smooth.

Then he used magic power to construct the shape.

With a humming sound.

Cao Rui extinguished the flame in the refining furnace and condensed the water spirit power to pour on the already formed jade pendant.

Zizizizi.

A white mist emerged.

Cao Rui used the object control technique to take out a piece of Lingyin jade pendant with a faint spiritual light from the mist and put it in front of him.

Because the materials used were very few, the Lingyin jade pendant had a thin layer, two fingers thick, and a faint blue color.

The fact that it was successfully refined was enough to show that Cao Rui's refining level had reached the top level.

"The quality is good."

"The cost of the materials is controlled within three spiritual stones."

"The next step is to engrave the magic array."

It is not difficult to engrave two magic arrays on such a jade pendant and connect them in series.

Cao Rui took a deep breath and began to engrave on the jade pendant with magic power.

First, the [Sound Transmission] on the front.

With Cao Rui's perfect 0-level magic array engraving, it only took a cup of tea to successfully engrave [Sound Transmission] on the front.

Next, Cao Rui started to perform the [Shadow Transmission] on the side.

Because this side had to be connected with the [Sound Transmission] on the front while engraving, the difficulty increased exponentially.

Even if Wu Qingxuan came, he might not be sure that he could succeed in refining.

Cao Rui calmed down a little and started to engrave directly.

As Cao Rui concentrated on engraving, the symbol pattern of [Shadow Transmission] began to appear little by little on the back.

Cao Rui needed to be particularly careful in the part of connecting with [Sound Transmission].

In this way, after more than half an hour, accompanied by a light sound, the whole body of the spiritual sound jade pendant glowed with a spiritual light.

"It's done." Cao Rui also breathed a sigh of relief.

Wu Qingxuan would definitely applaud Cao Rui when he saw this scene of entering the island.

Engraving two magic arrays on such a jade pendant, in terms of 0-level magic, the entire southwest of Yunzhou, and even the Yunzhou cultivation world, may not be able to compare with Cao Rui.

If it works the first time, it means it can work the next time, even in mass production.

Cao Rui held the Lingyin jade pendant, felt its transmission signal, and continued to fine-tune the magic circle.

"Well, this can add a storage function to store the signal characteristics of the fellow Taoist's Lingyin jade pendant."

"Add a 'dial' button, a 'hang up' and a 'connect' button, and add a positioning transmission function."

After Cao Rui's simple transformation, the first sound transmission jade pendant in the world of cultivation was successfully produced.

It took no more than an hour to refine the instrument and engrave the magic circle.

Cao Rui then refined the second Lingyin jade pendant.

Then he called Ye Yunyin to test the effect of the Lingyin jade pendant.

Holding two Lingyin jade pendants 10 meters apart, Cao Rui began to dial the audio and video function.

The jade pendant on Ye Yunyin's chest 10 meters away suddenly vibrated slightly.

Ye Yunyin clicked the connect button with his magic power.

The image of Cao Rui suddenly appeared in front of him.

The Lingyin Jade Pendant reproduced the scene within one meter around Cao Rui, and appeared in front of Ye Yunyin in a three-dimensional image.

Ye Yunyin was slightly surprised, and saw Cao Rui in front of him and said: "Elder Ye, how do you feel?"

"Master Cao, I admire this Lingyin Jade Pendant. Except for the shorter communication distance, the function can be said to be very good." Ye Yunyin commented.

"Well, now I will try the longest distance of communication with the Lingyin Jade Pendant alone. Elder Ye, please stand still and don't move."

Cao Rui flew back.

When he reached the range of about three miles, the connection of the Lingyin Jade Pendant was suddenly disconnected, obviously the communication distance was not enough.

However, these prove that Cao Rui's perfect level 0 spell engraving has pushed the effectiveness of this 0-level magic array to the maximum of three meters.

The communication distance of the sound transmission engraved by ordinary cultivators is generally within a range of ten meters without a communication medium.

First-level sound transmission can reach a distance of hundreds of thousands of meters, but the material of the jade pendant refined in this way must also be improved, and the cost is too high.

"Come on, let's first try to use the third-level magic circle in Qinglingfang City as an intermediary to see how far the Lingyin Jade Pendant can transmit the message."

"Every defensive formation is a natural signal radiator."

"The sect's fourth-order formation can even reach the entire southwest of Yunzhou."

"Let's take a look at the effectiveness of this third-level formation in Qinglingfang City."

Cao Rui returned to the training tower and took out the Qinglingfang City third-level defense 꺶array께 array plate for fine-tuning.

께There is a first-level array [far transmission] set up on the array plate for the purpose of arranging microphones.

In the past few months, Cao Rui had specialized in the first-level magic formation [Far Transmission] and had already perfected it.

With the help of Wu Qingxuan, Cao Rui has completely understood the connection between the sect's fourth-level formation and the communication formation.

Cao Rui connected it to the transmission frequency of Lingyin Jade Pendant in the array.

Cao Rui flew to the locations where the array disks were placed throughout the city, and also made fine adjustments to connect the signal frequency of the Lingyin Jade Pendant to the third-order array.

It sounds simple in words, but in practice, without a perfect level understanding of [Messaging], and without a thorough understanding of the basic understanding of level 0 magic circles, it is impossible to reach Cao Rui's level.

"Elder Ye, please cooperate with me again."

Cao Rui took out the spiritual sound jade pendant and dialed the spiritual sound jade pendant in Ye Yunyin's hand.

There was no lag in Ye Yunyin's connection process. Obviously, even if the signal was transferred through the magic circle, there would be no lag in the speed shown.

Cao Rui summoned Fei Yu and began to fly away outside Fang City.

In the video, as Cao Rui gets further and further away from Fangshi, Ye Yunyin's expression becomes more and more surprised.

"If it's a magic circle, can the communication distance be so far?"
