Spirit insect contract?

This was a very famous contract method in the Yunzhou cultivation world, so Cao Rui naturally knew about it.

Cao Rui nodded slightly: "Okay, but I don't have any contracted spirit insects on me for the time being..."

Before he finished speaking, Yun Changsheng had already taken out a pair of thumb-sized contracted spirit insects from his body.

"This is a second-level life-weaving shadow worm."

"It can also have a restraining effect on us Foundation Establishment cultivators."

Yun Changsheng was well prepared...

Cao Rui nodded slightly, and then compiled the Taoist oath with Yun Changsheng.

Cao Rui's task was naturally to determine the ownership of the mineral veins and the island, while Yun Changsheng's task was to focus on the delivery of the spirit stone payment.

After the two sides considered it comprehensively and concluded some non-aggression agreements, the Daoxin Oath came out.

"I, Cao Rui, swear here!"

"I, Yun Changsheng, hereby swear..."

The two of them recited the Taoist oath at the same time.

For cultivators, the Dao Heart Oath is no joke.

After they completed the foundation building, this feeling became more and more obvious.

When the last word fell, Cao Rui suddenly had a wonderful feeling.

He seemed to really feel that there was some mysterious existence above the nine heavens, watching himself and Yun Changsheng at the bottom of the mine through the thick rock layer.

It was an indescribable sense of majesty that made people feel awe.

As the two of them swore their vows, the contracted spirit insects slowly merged into their brows.

The integration of the contracted spirit insect did not bring about any special changes, but it did create a vague connection between them.

Only then did Yun Changsheng breathe a sigh of relief.

Cao Rui also relaxed a little.

According to the contents of the Dao Heart Oath, Cao Rui took out 20,000 spirit stones, put them into a storage bag, and handed it to Yun Changsheng.

Yun Changsheng probed his spiritual sense into the storage bag and confirmed the number of spirit stones in the storage bag.

After paying 20,000 spirit stones in one go, Yun Changsheng had no doubt about Cao Rui's sincerity.

"Fellow Daoist Yun, the mining speed is still a bit slow. I hope to add some manpower." Cao Rui said.

Currently, there are fifteen Yun family disciples in this Lingwen Xuanjing mine. Most of them are in the middle stage of Qi Refining, and there are only three in the late stage of Qi Refining.

The daily output after refining is about ten kilograms.

The main thing is that after the ore is mined, it needs to be purified by monks with magic power. A large piece of ore will eventually be refined to only the size of a thumb, and this step is quite time-consuming.

According to the signal tower refining material formula given by Wu Qingxuan, one signal tower requires ten kilograms of spiritual pattern crystal.

In other words, at the current rate, the spiritual pattern crystals mined every day are only enough to build one signal tower.

We have to speed up.

Yun Changsheng nodded and said, "No problem. I will send more family members over to increase production."

The salary of Qi Refining cultivators is low, and sending more of them would only cost a few hundred more spirit stones.

Yun Changsheng can still support this.

There were still more than 100 kilograms of spiritual pattern black crystals in stock in the mine, and Yun Changsheng generously gave them all to Cao Rui.

Yun Changsheng, who had received 20,000 spirit stones, was in a good mood and invited Cao Daoyou: "So, would you like to return to the East Sea Market with me to experience the sea beast meat feast? Or..."

"I will stay on the island for the time being. This place is far away from the Spirit Beast Sect, and it is not convenient for you to deliver the goods."

Cao Rui decided to stay on the island for a while, waiting for the production of the spiritual crystal, and taking a look at the situation of hunting sea monsters here.

Seeing this, Yun Changsheng stopped trying to dissuade him. Now that the island belonged to someone else, the autonomy naturally lay with Cao Rui.

The next day.

Yun Changsheng sent thirty Qi Refining disciples over.

With full operation, the daily output of this mine has been increased to 50 kilograms.

Cao Rui asked Ye Yunyin to return to Qingling Market first. After all, Zhang Mo had just been promoted to the Foundation Establishment stage. It would be easy for the demon cultivators to take advantage of him if he was guarding both Qingling Market and Qingling Mine.

Ye Yunyin, a sword cultivator at the sixth level of foundation building, is also needed to guard the market.

"Then you should be careful, Chief Cao."

"When we get back to the market town, I will send a few reliable disciples over to help with the chores." Ye Yunyin said.

Cao Rui watched Ye Yunyin leave on the Thousand Feather Crane.

Cao Rui himself built a wooden house on a high ground on the island to live in temporarily.

in this way.

Three months passed in a blink of an eye.

During these three months, Cao Rui did not need to refine the Lingyin Jade Pendant, and all the spiritual medicine materials on his body were used up. The Bailudan spiritual medicine in the Zhantian Bottle was not yet mature.

It just so happened that he spent all his energy on practicing magic.

Before this, Cao Rui had been busy refining elixirs and weapons, so he was far behind in magic.

After three months, the foundation-building magical power [Conical Divine Thorn] was finally perfected. With Cao Rui's current spiritual awareness, he can exert extremely terrifying power and pose a great threat to cultivators in the early stage of foundation-building.

After advancing to the foundation-building stage, the experience points gained from practicing the five first-level five-element spells and sword-controlling skills increased several times faster.

In three months, several spells were mastered.

Now, Cao Rui controls the golden sword and flies through the air at such a fast speed that others would think that he is a foundation-building cultivator who excels in speed.

At the Lingwen Xuanjing mine, Cao Rui harvested 4500 kilograms of Lingwen Xuanjing in three months.

Ten disciples of the Lingshou Sect who were in the late stage of weapon refining from Qingling Market were sent to the island by Ye Yunyin to assist Cao Rui in managing the island.

Cao Rui was still quite moved. These ten disciples all came here voluntarily. They crossed the spiritual energy vacuum area and spent about a month to reach the island.

Naturally, Cao Rui generously increased the salary of the ten disciples by three times and gave them the Yellow Dragon Pill as a reward.

Operations on the island are also back on track.

After knowing that they were working for others, the Yun family members on the island actually worked harder when digging and smelting ore.

Although Cao Rui felt that the speed of mining the mineral vein was still a bit slow.

So on this day, Cao Rui flew out on his sword and headed straight for the East China Sea Xiuxian Market.

After arriving at the market town, Cao Rui originally wanted to meet Yun Changsheng.

However, I learned that this guy was practicing in seclusion.

Probably after getting Cao Rui's 20,000 spirit stones, he went to buy the corresponding spiritual medicine for cultivation.

A senior official of the Yun family received Cao Rui.

Cao Rui also stated his purpose - to use his own spiritual stones to recruit a group of independent cultivators to go to the island to speed up the excavation progress.

This time, Cao Rui only wanted a casual cultivator in the late Qi Refining Stage.

Each independent cultivator is paid a monthly salary, which is equal to that of a cultivator of the Yun family.

In the market town, not all cultivators are willing to fight against the monsters in the endless sea.

With the cooperation of the top leaders of the Yun Family Market, Cao Rui quickly recruited fifty independent cultivators as soon as the news was released.

On that day, Cao Rui hired a large ship to transport this group of Qi Refining cultivators to the small island with a mineral vein, and handed them over to the jurisdiction of several Spirit Beast Sect disciples under his command.

A few days later, as this group of independent cultivators, all of whom were in the late stage of refining, gradually got the hang of it, the daily output of the mine also increased by 140 kilograms!
