The Mortal's Path to Immortality

Cao Rui was very satisfied with the results of his closed-door cultivation.

After completing the [Spirit Pattern Casting Source Technique], he began to refine the signal tower first.

As for the blasting needles, he decided to keep 30 second-level blasting needles of better quality.

As for the other second-level blasting needles, he took the time to go to the market and gave them to Sun Ming for sale.

This decision unexpectedly brought good news.

Once this second-level auxiliary magic weapon was sold, it was quite popular among the Qi Refining Period casual cultivators.

All the second-level blasting needles were quickly sold, and Cao Rui received a return of about 60,000 spiritual energy.

In this way, he not only recovered the more than 50,000 spiritual energy he had invested before, but also earned more than 10,000 spiritual energy.

It was a pleasant surprise.

This is the second-level [Remote Transmission].

Cao Rui would spend half of his time every day refining equipment to improve his [Spiritual Pattern Casting Source Art].

The remaining half of the time was used to engrave [Far Transmission].

After his unremitting efforts and diligent engraving, it took only three months for Cao Rui to successfully practice [Far Transmission] to perfection.

Cao Rui condensed the experience beads of all the arrays from the inheritance room of the Refining Institute, but he had no time to accumulate experience.

[Far Transmission] was also the first second-level array that Cao Rui mastered and perfected.

"When I have free time, I must practice all these arrays to perfection." Cao Rui thought to himself.

You know, except for the 0-level array, which is a gift from heaven and earth, all other arrays are created by humans.

Now, Cao Rui has completely mastered all the 0-level arrays, and as the number of high-level artificially created arrays he has mastered continues to increase, he has gradually developed some unique ideas of his own.

"However, it is conceivable that it will take a long time to really create a desired array." Cao Rui said.

After all, to innovate the array, it is not just a matter of splicing the various array modules together, but it requires repeated attempts and modifications to ensure that each module can work perfectly together.

In this process, not only a deep understanding of the principles of various arrays is required, but also sufficient patience and perseverance.

However, this challenge makes Cao Rui feel slightly excited.

He knows that only by constantly challenging himself can he truly improve his strength.

Therefore, he decided to start with some simple arrays when he is free and gradually accumulate experience.

For example, when upgrading the Lingyin Jade Pendant, you can try to combine the 0th level [Sound Transmission] and [Image Transmission] to create a magic array between the 0th level and the 1st level.

It is not necessary to enhance the power of the magic array. It is a good choice to enhance the function of the magic array from the side and make the function more variable.

Cao Rui has some ideas, but it still needs experiments before it can be developed accurately.

In addition, Cao Rui also thought of other interesting ideas, such as adding a live broadcast function.

Through the clever design of the magic array, Cao Rui may be able to develop a magic array to achieve this function.

Of course, to realize these ideas, it is necessary to make major changes to the existing magic array, which will undoubtedly increase the difficulty and risk.

However, this is all for the future, and Cao Rui quickly put away his magic array fantasy.

Because next, after the refining technique and the magic array are perfect, he can start to work on the refining of the high-quality signal tower.

On this day, Cao Rui prepared a set of refining materials for the signal tower by himself, borrowed the second-level refining furnace of the Refining Institute, and began to refine the signal tower.

Although Cao Rui called it a tower.

But in fact, the signal tower designed by Wu Qingxuan is only one meter high.

When it is activated, the user only needs to install a spirit for it.

The signal tower is only used for communication, so the consumption of spirit is very small, and a piece of spirit can be used for a long time.

The structure of the signal tower magic weapon designed by Wu Qingxuan is very reasonable. This is his blood in the past few years, so Cao Rui did not make a big change.

Cao Rui used [Spirit Pattern Casting Source Jue] to refine the magic weapon, which is completely different from the basic refining technique.

Unlike the basic refining, Cao Rui, who has mastered the second-level refining technique, will refine the weapon and engrave the magic array at the same time.

The magic array will be engraved on the magic weapon in advance using the refining technique when it is refined.

In this way, the engraving of the magic circle will be more concealed, practical, and more effective.

After that, the Lingyin jade pendant refined by Cao Rui with the second-level refining technique will be more effective.

"Well, the signal tower must be embedded with the contact frequency of the Lingyin jade pendant, and the Lingyin point symbol system must be added."

In Cao Rui's idea, the signal tower will directly give the person in charge of the immortal cultivation forces near the deployment point.

Cao Rui will give him the right to recharge Lingyin points.

Of course, the Lingyin points used for recharging in their accounts must be purchased from Cao Rui with real spiritual materials.

For every Lingyin point sold, Cao Rui will give rebates with Lingyin points, which is their way of making money.

Although the number of Lingyin points recharged is not large now, when the Lingyin Jade Pendant's functions are opened in the future, the monks will gradually recognize Lingyin points as an online transaction currency instead of Lingyin, and the number of Lingyin points recharged will definitely increase greatly.

By then, the signal tower will become a hot commodity.

Every monk or force that holds a signal tower will maintain the signal tower on their own and will also become a loyal supporter of Lingyin Jade Pendant and Cao Rui.

The refining of the signal tower lasted a whole day, and Cao Rui finally succeeded in refining a perfect signal tower.

Perfect level [Spiritual Pattern Casting Source Art], perfect level second-level [Remote Transmission].

The signal tower in Cao Rui's hand can be said to be perfectly refined.

Cao Rui has superimposed and engraved ten second-level [Remote Transmission] alone!

The standard number of superimposed arrays for second-level magic tools is ten.

Ten arrays have completely exceeded the standard requirements.

Moreover, ten is not the limit. Cao Rui thinks that after the proficiency of refining is improved, Cao Rui can superimpose fifteen [Remote Transmission] at most within the tolerance range of the material! 】

"Try it, the transmission range of the signal tower, originally expected to be about a thousand miles, now it should be far more than a thousand miles!"

Cao Rui is quite confident in his refining skills.

After activating the signal tower.

Cao Rui flew up on his sword and flew far away.

Soon he reached the mountain gate, and Cao Rui flew quickly with his golden sword.

At a speed of more than 3,000 miles in an instant.

Cao Rui watched the Lingyin jade pendant in his hand gradually transmit the signal.

"It's almost 2,000 miles, which is doubled!"

Cao Rui also didn't expect that his perfect second-level refining technique and perfect second-level array could bring such a great chemical reaction.

This means that the number of signal towers Cao Rui needs to deploy can be reduced by almost half!

The cost is greatly reduced!

"The number of spiritual pattern crystals is more than enough."

"But signal towers and Lingyin jade pendants are consumables after all. There is only benefit and no harm in hoarding spiritual pattern crystals." Cao Rui said.

After testing the range of the signal tower, Cao Rui flew up on his sword and returned to the mountain gate.
