I can gather experience beads

"Not much, just one hundred top-grade spirit stones!" Tianji baby replied.

One hundred high-grade spirit stones are approximately equal to one million low-grade spirit stones.

Do you really think others are rich?

Cao Rui simply ignored this option.

Baby Tianji said: "However, the ultra-long-distance transmission of Tianji Fortress must carry the ultra-mass object of Tianji Fortress itself."

"If you can build a small teleportation array in advance to only transport a few people, the number of spirit stones required will definitely be much less."

When Cao Rui heard this, his eyes lit up slightly.

Although it is not realistic to set up a teleportation array back to Yunzhou at present, because the teleportation array requires the establishment of teleportation bases on both the starting point and the end point.

But now that Cao Rui is in Qingzhou, he can try to leave a few teleportation points in Qingzhou.

Who knows, maybe you will have important business to come to Qingzhou next time?

For each random teleportation of Tianji Fortress thereafter, Cao Rui could leave behind several teleportation points.

In this way, Cao Rui can visit the Thirteen States in Qingqiong Realm in the future.

By searching for treasures of the five elements' spiritual roots, the chances of finding spiritual medicines for golden elixirs and Nascent Souls in the future will be greatly increased.

There are also many options for fighting against the demons.

As for the knowledge about the teleportation array, you have to know that this is the Tianji Fortress arranged by Tianjizi, the master of array mechanisms. How could there be no knowledge about the array in the fortress?

"Baby, tell me which level in the Tianji Fortress has relevant knowledge about the teleportation array." Cao Rui said.

"Cao Rui, do you want to learn about teleportation arrays?" Tianji baby asked curiously.

"Yes, Tianji Fortress randomly teleports to various states, which gives me the opportunity to set up teleportation points." Cao Rui said.

"Come with me." Baby Tianji led Cao Rui to a teleportation array.

"I remember, it's this teleportation array." Baby Tianji said, pointing to a teleportation array.

"The name of this level is [Time Transmission]. The content is to complete the formation within the specified time according to the guide's instructions, and you can pass the level."

"In fact, if you pass the level, you can almost be called a formation master."

"However, this level will take a very long time, Cao Rui, you should be mentally prepared."

No matter how long it takes, you have to learn how to set up the teleportation array. This is a rare opportunity.

Cao Rui nodded gently, then patted Zixiao's head gently and said softly, "Go, stay with Tianji baby for a while."

After saying that, he turned his head and looked at baby Tianji.

"Come, come, come here!" Baby Tianji quickly flew in front of Zixiao.

Zixiao looked at the strange and powerful being in front of him and couldn't help feeling a little afraid, but he also understood that his master Cao Rui had important things to deal with, so he finally mustered up the courage to fly over Tianji baby and tightly wrapped himself around Tianji baby's neck, like a purple scarf.

After doing all this, Cao Rui took a deep breath, adjusted his state, then raised his foot and stepped into the teleportation array.

A moment later, the teleportation array flickered, and Cao Rui's figure disappeared in the central square of Tianji Fortress.

Tianji baby watched Cao Rui go in, then pulled Zixiao off and held it in his hand: "Come on, call me Master Bao!"

"Little guy, when did daddy bring you in? Tsk tsk, a real dragon, Cao Rui must not know what a real dragon means..."

Baby Tianji looked at Zixiao and wondered how to educate this baby dragon who was as innocent as a blank sheet of paper.

......

the other side.

After Cao Rui was teleported, he appeared in a large study.

This book room is very spacious, with countless bookshelves and books, just like a library.

Of course Cao Rui knew that this was just an illusion.

After looking around, a white light flashed in front of him, and a human-shaped shadow appeared floating in the air.

The face of the human figure could not be seen clearly, but it exuded a powerful aura.

"【Teleportation Time】, this level tests the cultivator's ability to learn the teleportation formation. I will give the questions and you will do them. You will pass after completing all the exercises." A voice came from the human-shaped light and shadow.

Cao Rui nodded slightly, indicating that he understood.

"The first question is the engraving of the fourth-order teleportation array."

"Please complete the engraving of the fourth-order teleportation array within three days."

The human-shaped light and shadow surged, and then formed a glittering teleportation array in the air.

This teleportation array looks extremely complicated, with densely packed runes intertwined together, making the eyes dizzy.

"A fourth-level magic array rune?"

Cao Rui looked at the teleportation array in the air, and a trace of solemnity flashed in his eyes.

Although he had some knowledge of the teleportation array, it was still difficult to complete the engraving of a fourth-level teleportation array within three days.

However, he did not retreat. Instead, he took a deep breath and began to carefully study the teleportation array in the air.

This was the first time Cao Rui came into contact with a fourth-order magic array rune. The highest level of magic array runes Cao Rui had come into contact with before was only a third-order rune.

At this moment, a large crystal plate suddenly appeared in front of Cao Rui. This crystal plate should be used to engrave a magic circle for him.

It has the same function and effect as the metal plate provided by Wu Qingxuan.

He looked at the crystal plate in front of him and thought to himself, "With such a complex inscription, an inexperienced cultivator would definitely not be able to pass this level. However, I have experience in engraving a third-level magic array, and with the help of the experience beads, it will not be difficult to complete this first lesson."

He took a deep breath, cast his gaze towards the fourth-order magic circle runes in the air, and then began to concentrate and prepare to engrave the magic circle.

"Three days..." Cao Rui muttered to himself. He knew that time was tight, but he still had confidence in himself.

He stretched out his right hand, tightly grasped the book crystal plate, and at the same time used his spiritual sense to lock onto the fourth-order magic array runes in the air and began to condense magic power.

As he moved, rune patterns appeared in his mind one after another, and these rune patterns gradually formed a complete fourth-order magic circle.

He stared at the runes intently, constantly adjusting his engraving speed and strength to ensure that each rune could be engraved accurately on the crystal plate.

"The runes of the fourth-tier magic array are indeed complicated. Could it be that Tianjizi created them? If it weren't for the fact that my spiritual awareness has far surpassed that of ordinary foundation-building cultivators due to my cultivation of the Shenyuan Jue, I would probably find it difficult to even detect the rune patterns." Cao Rui marveled inwardly as he looked at Meng Ke.

He discovered that this fourth-order magic array rune was much more complicated than the third-order magic array he had engraved before, and it required more spiritual power to engrave successfully.

If his spiritual awareness wasn't strong enough, he probably wouldn't be able to complete the task at all.

“I’m afraid that the first people to be screened out at this stage will be the foundation-building cultivators with insufficient spiritual awareness.” Cao Rui secretly rejoiced in his heart that his spiritual awareness was strong enough after practicing the Shenyuan Jue to cope with this challenge.

Cao Rui was certain.

He continued to concentrate and put all his energy into engraving the magic circle.

A cup of tea later, Cao Rui was defeated.

The crystal plate in his hand automatically shaved off a layer.

However, Cao Rui was not disappointed, because the experience value of the experience beads in his mind increased a lot.

"At this rate, it will take a few hours to get started and complete this question."

Cao Rui began to continue engraving the fourth-level magic array runes. Even with Cao Rui's current rune attainments, he still failed continuously, which shows the difficulty of the fourth-level magic array runes.

A few hours later, Cao Rui failed again, but the experience beads in his mind had already been filled with the memories of repeated failures.

"Break the experience bead for me!" Cao Rui gently tapped the experience bead in his mind with his mind.
