I can gather experience beads

Cao Rui took out a storage bag containing 50,000 spirit stones and handed it to Ye Yunyin.

The raw materials purchased with these 50,000 spirit stones can last for a long time.

Ye Yunyin's mouth twitched, but he still took the storage bag: "Then you can go to the mine for me. There will be a batch of spirit stones to be delivered recently and need to be transported back to the sect. You can give it to the sect master."

Cao Rui nodded: "No problem."

I just happened to be going back to the sect to ask the Weapon Refining Institute for help in refining the Lingyin Jade Pendant.

There's absolutely no problem handing over the spirit stones along the way.

Ye Yunyin has always been a man of few words. He picked up the spiritual tea brewed by Cao Rui, took a sip, and then flew towards the northern part of Yunzhou without stopping.

Watching Ye Yun disappear into the sky, Cao Rui couldn't help but sigh: "Elder Ye and the Refining Institute have helped me in every possible way. When the Lingyin Jade Pendant starts to make a profit, I will give them a big gift package of Lingshi!"

In Cao Rui's heart, Ye Yunyin is a respectable elder in the sect, and the Equipment Refining Institute has always given him great support and help.

Perhaps in their own eyes, this is just normal mutual assistance among fellow disciples.

Although Cao Rui cannot repay them immediately now, he always remembers this kindness in his heart.

The next day.

In the early morning, it was just dawn.

Cao Rui opened his eyes and stood up from the cushion on the seventh floor of the training tower, flying on his sword to the Qingling mine.

A streak of golden light flashed across the sky. The golden sword enabled Cao Rui to fly the sword at an extremely fast speed. The hundred-mile distance between the market town and the spiritual mine was covered in the blink of an eye.

Today is the day when the mineral veins meet the spiritual stones.

At the Qingling Mine, Cao Rui met the true disciple in charge of management and successfully completed the handover procedures with the certificate given by Ye Yunyin.

This time the output is equivalent to one quarter's output of the Qingling Mine, and the number of spirit stones is quite considerable.

After an 80:20 split with the Yunshui Sect, they could still obtain more than 40,000 spirit stones.

Most of the mid-grade spirit stones were naturally occupied by the Spirit Beast Sect.

Cao Rui secretly sighed in his heart, no wonder the Lingshou Sect had gone to war with the Yunshui Sect over this spirit stone mine.

After all, the profits from the spirit stone mine are so lucrative, who wouldn’t want to get a piece of the pie?

Took the spirit stone storage bag.

Cao Rui summoned Black Feather and flew straight to the sect.

After one day and one night.

At noon the next day, Cao Rui just arrived at the Spirit Beast Sect.

Cao Rui first went to the back mountain to practice in the pagoda, and handed over the spirit stone output of the spirit stone mine in the next quarter to Lu Jiuxiao.

After Lu Jiuxiao took the storage bag, he looked at Cao Rui with curiosity: "I heard that in addition to refining pills, you have also been refining equipment recently? The Lingyin Jade Pendant seems to have caused quite a stir."

Cao Rui replied, "It's just a minor fight."

"How is your mastery of the Bailu Pill?" Lu Jiuxiao was not aware of the impact that the Lingyin Jade Pendant would have in the future. What he was most concerned about was Cao Rui's alchemy level.

Cao Rui nodded slightly: "I'm almost there."

"Yes, it's only been two months and you've already reached the threshold. You are indeed an unparalleled alchemy genius." Lu Jiuxiao said with joy when he heard that.

"Do you have enough spiritual medicine materials?"

Cao Rui replied: "It's enough for now, so don't bother the sect."

This has caused the sect's foundation-building cultivators to be deprived of three years' supply of Bailu Dan.

If he spoke again, Cao Rui would feel uncomfortable.

The most important thing is that the spiritual medicine materials on hand are enough for Cao Rui to complete the Bailu Pill.

After the Bai Lu Dan was completed, with the income from the Lingyin Jade Pendant, the medicinal materials for the Bai Lu Dan in the Zhangtian Bottle were mature and enough to support Cao Rui's practice.

"Okay, then keep up the good work. When you run out of spiritual medicine materials, come back to me. The sect will help you find a way to gather all the spiritual medicine materials. We will always be able to support you until the day when you can completely master the Bailu Pill."

"Only with the Bailu Pill as a foundation, we dare to give you the materials for the Foundation Establishment Pill to practice." Lu Jiuxiao said.

Bailudan is the lowest level elixir for cultivation in the foundation building period.

Lu Jiuxiao’s goal has always been the Foundation Establishment Pill.

As long as Cao Rui can refine the Foundation Establishment Pill, the consumption of spiritual medicinal materials for the Bailu Pill will be nothing at all.

Cao Rui nodded in agreement. The materials for the Foundation Establishment Pill were so expensive, he had to at least practice the Yi Mu True Fire Alchemy Technique to perfection, and perfect a few more second-level pills to enrich the pharmacology of the second-level pills before trying to refine them.

After delivering the spirit stones and coming out of the cultivation pagoda, Cao Rui went to the Alchemy Institute and solved a few problems that the deacons and disciples had with alchemy during this period.

He fulfilled his obligations as the head of the Alchemy Academy.

Just now he flew into the air and rushed to the weapon refining institute.

Lingfeng of the Equipment Refining Institute.

Inside Wu Qingxuan's refining room.

Cao Rui took out the refining materials for the Lingyin Jade Pendant.

"Master Wu..."

Wu Qingxuan stopped Cao Rui from speaking: "I understand, leave it to me."

Wu Qingxuan took the storage bag and immediately called on the disciples in the Weapon Refining Academy to work hard on refining.

The disciples of the Weapon Refining Academy are not like those of the Alchemy Academy. Except when new inner disciples join the academy, they do not have so many magical instruments to refine.

I have a lot of free time everyday, engraving magic arrays on metal plates to hone my equipment-refining skills.

The disciples of the Equipment Refining Academy are actually quite happy to have this opportunity to refine magical instruments in large quantities, as it allows them to increase their own equipment refining experience.

Cao Rui still participated in refining equipment with the disciples of the Equipment Refining Academy.

This time, the disciples of the Equipment Refining Academy had more than 5,000 Lingyin Jade Pendants as a foundation, so the speed of refining equipment was much faster.

It took seven days to refine fourteen thousand Lingyin jade pendants.

When Cao Rui held the storage bag full of Lingyin jade pendants, he couldn't help but sigh in his heart that it was better to have the support of the sect.

Wu Qingxuan took Cao Rui to talk about the signal tower: "For the signal tower, after many experiments in refining instruments, I have basically determined the most cost-effective and low-cost materials. Taking a first-level magic instrument as the standard, the cost is about 300 spirit stones; taking a second-level magic instrument as the standard, the cost is about 3,000 spirit stones."

"If we want to continue to increase the signal tower's range of influence, we can only make a breakthrough in the first-order magic array [Remote Transmission]."

"My [Remote Transmission] has only reached the minor success stage. If I can find someone with a higher level of [Remote Transmission] to engrave the array, the effect of the array will be stronger. Moreover, they can also stack multiple [Remote Transmission] on the signal tower to multiply the effect."

After hearing what Wu Qingxuan said, Cao Rui thought that it would be quite difficult to find a weapon refiner who could practice [Teletransmission] to a very high level in a short period of time.

It would be better for him to take time out every day to improve his [Remote Transmission] experience points and practice it to perfection.

If one could achieve the same result as Zhenren Shenyuan's [Golden Sword] and engrave ten magic arrays at once, the signal tower's communication capabilities would certainly be greatly enhanced.

Wu Qingxuan said again at this time: "In addition, the spiritual pattern crystal is a problem."

"The spiritual pattern black crystal material needed to refine the signal tower is not comparable to the spiritual sound jade pendant."

"As for the materials of the Spiritual Pattern Mysterious Crystal, we must prepare in advance."

Cao Rui nodded slightly. After Ye Yunyin came back from central Yunzhou this time, he asked him to find out the news about the Lingwen Xuanjing in detail.

It would be best if we could find a vein of spiritual pattern black crystal.
