I can gather experience beads

"Also, what shape and name should the communicator be given?"

Lingyin jade pendant?

Microphone?

Heart Mirror? Voice Transmission Bead?

Finally, Cao Rui decided to give it the shape of a jade pendant for easy carrying, and named it "Lingyin Jade Pendant" as the name suggests.

Remote communication is only the first function. Cao Rui can also add capabilities such as video calls and location sending in the future.

Just like a certain fruit in the previous life, its functions are updated slowly, and each iteration attracts monks to rush to buy it.

In the future, when Cao Rui's equipment refining level improves, it is not impossible for him to evolve into an online shopping mall or a Douyin version of the immortal cultivation world.

In the later stage, if Cao Rui makes a breakthrough in the level of refining equipment and the communication distance reaches the level of a communication array, then it will basically be the product of a massacre in the Yunzhou immortal cultivation world.

Just like the Lingjian Sect's exclusive spiritual ship for transporting spiritual tools, the Qingling Xiuxian Market is the first thing that comes to mind when the communication spiritual tools are mentioned.

Only in this way can you make money.

"Besides, there are the five magic swords of the Great Five Elements Sword Formation."

Cao Rui summoned the golden sword from his storage bag.

Ten first-order magic arrays are engraved on the golden sword.

There are two types of magic arrays, five in each type.

Cao Rui examined the magic arrays on the walls of the inheritance house of the Equipment Refining Institute one by one.

It was discovered that only one type of magic array existed on the wall, and that was the first-order [Swiftness].

Five first-level [Agility]. No wonder the speed of the casual cultivator in the Qi Refining Stage when flying this flying sword was comparable to that of the Foundation Establishment Stage.

For another first-level magic array, Cao Rui found the jade slip of the Great Five Elements Sword Array and read it carefully. From the method of refining the five magic swords of the Great Five Elements Sword Array, he found out that this other magic array was called [Blade], which had a similar effect to the first-level [Sharp], but was even more powerful.

However, Master Shenyuan obviously did not expect that the magic array that every cultivator in ancient times could learn would be lost today.

Therefore, the refining method only mentioned the name of the magic circle, but not the specific rune pattern of the magic circle.

"I don't have any illusion or confusion from the magic circle on the water sword."

"It is quite difficult to refine the five magic swords of this Great Five Elements Sword Formation according to the original version of Master Shenyuan."

"Forget it, let's first condense all the experience beads on the magic circle on the wall."

Putting away the golden sword, Cao Rui picked up the metal plate and began to engrave a magic circle.

The magic arrays on the wall were engraved on the wall after being magnified. After Cao Rui locked them with his spiritual sense, he began to engrave them on the metal plate in the same way.

Unlike when he was engraving behind Wu Qingxuan, Cao Rui failed three times and spent three hours before he successfully condensed the experience beads for the first magic circle.

In this way, it took Cao Rui five days to condense all the sixteen first-level magic arrays on the wall into experience beads.

After condensing the experience beads, Cao Rui can increase the experience value of the experience beads by relying on the memory in his mind the next time he engraves them, and he does not need to stay in the inheritance house.

Cao Rui also tried to condense the experience beads of the second-level magic circle.

It ended in failure.

Although his spiritual awareness is equivalent to the third level of the foundation-building period, the requirement for the second-level magic array is that it can only be initially engraved in the late stage of the foundation-building period.

When Cao Ruizi tried, he couldn't see the second-order magic array runes clearly because his spiritual power was not strong enough. If he tried to engrave them by force, he would also have a severe headache.

Cao Rui had no choice but to give up.

After coming out of the inheritance house, Cao Rui found Wu Qingxuan and explained his idea of ​​the Lingyin jade pendant.

After hearing this, Wu Qingxuan frowned slightly. He was not refuting Cao Rui's wild idea, but was seriously thinking about the feasibility of the plan for Cao Rui.

"The communication array of our Spirit Beast Sect uses the powerful radiation ability of the sect's fourth-level formation to expand its communication capabilities to the entire southwest of Yunzhou."

"The main material of the communication array, the Spiritual Pattern Mysterious Crystal, is also very valuable."

"According to what you said, the main material of those signal towers should also be spiritual crystal. In addition, they are engraved with a first-level magic array. There must be someone to maintain the signal towers, right?"

"It is feasible, but it requires a lot of effort and time." Wu Qingxuan said.

Cao Rui cupped his hands and said, "Please help me, Master Wu. After the matter is completed, I am willing to give you 30% of the profit of the Lingyin Jade Pendant."

After hearing this, Wu shook his head and said, "30% is too much. If you really want to give it, half or 10% will be enough."

"In the southwest of Yunzhou, there are about 10,000 inner and outer sect cultivators from the three major sects."

"The number of independent cultivators is not 300,000, but at least 200,000."

"If each of these independent cultivators had a Lingyin Jade Pendant, the benefits would be unimaginable."

"This is just the southwest of Yunzhou. There are millions of cultivators in the entire Yunzhou. If everyone has a Lingyin Jade Pendant, then... "

Cao Rui couldn't help but smile in his heart as he listened to Wu Qingxuan's imagination of the future for him.

However, Wu Qingxuan's thinking was too simple, he only considered the value of the jade pendant.

Without imagination to support him, when everyone has their own product, he can bring about huge influence by making slight changes to the product.

Wu Qingxuan was persuaded by himself: "Cao Rui, your idea is very good."

"But the premise of everything is that we have to control the cost well."

"Technology and cost issues are the main problems that need to be solved at present." Wu Qingxuan said incisively.

Cao Rui nodded and said, "I want you, Wu Shouzu, to help me with the preliminary research of the signal tower artifact. I will be responsible for the little Lingyin Jade Pendant."

Considering the expensive material of Lingwen Xuanjing, the Lingyin jade pendant cannot be very large.

But in Cao Rui's idea, at least two level 0 magic arrays need to be engraved on this small Lingyin jade pendant.

One is naturally [Voice Transmission].

The other one is naturally [Shadow Transmission].

Combining the two, the Lingyin Jade Pendant can enable video calls.

Just imagine activating the Lingyin Jade Pendant to contact the person you want to contact.

After the other party is connected, the Lingyin Jade Pendant will directly project a spiritual light, condensing a real-life projection of the other party in front of you to talk to you.

It felt like being there in person, or like being projected and transmitted by a Jindan cultivator.

I believe that as long as the news of someone using the Lingyin Jade Pendant spreads, those who witness it will be willing to spend spirit stones to purchase the jade pendant.

The only difficulty is that in order to restrain two 0th-order magic arrays on such a small Lingyin jade pendant, one needs to practice the engraving of the 0th-order magic array to an extremely high level.

Cao Rui felt that only he, who possessed the experience beads, could achieve this in a short period of time.

First, deal with the Lingyin Jade Pendant and the 0th-order magic array on it. After that, Cao Rui also needs to continue to improve the realm of the st-order magic array on the signal tower before he can upgrade the signal tower and increase the radiation range, thereby reducing costs.

Cao Rui just happened to still be waiting for the sect's 500 doses of Bailu Dan spiritual medicine ingredients to be delivered in July.

So this time he concentrated on his seclusion in the sect, focusing on improving his weapon refining array every day. Occasionally, he would go to the Alchemy Academy to guide the two deacons and disciples, and explain to them the refining techniques of the Fire Lotus Pill.

A month later, at Qingling Market, Zhang Mo successfully advanced to the Foundation Establishment stage, and Cao Rui felt more at ease staying at the sect.
