I can gather experience beads

Deep inside Baixian Palace.

There is a side hall.

This side hall was specially built for this ancient teleportation array.

There are at least two foundation-building cultivators from the Bai family guarding the place throughout the year.

Cao Rui and Yue Xiying followed Bai Luojing into the hall.

At a glance, I saw a teleportation array in the middle of the hall.

Bai Luojing started to introduce: "The history of the Bai family is long enough. This teleportation array is a relic of the Bai family from ancient times."

"In ancient times, the Bai family used this teleportation array to reach Huazhou! They could communicate and cooperate with the cultivators in Huazhou!"

"However, I don't know when this teleportation array was destroyed. The Bai family once asked someone to repair it, but it was ineffective."

Huazhou? Cao Rui's heart was slightly moved.

Huazhou is a state in the central part of Qingqiong Realm, connected to both Hongzhou and Yuzhou.

If it is possible to connect with Huazhou and persuade the immortal cultivation community in Huazhou to help the Demon-Slaying Alliance, it will indeed be the best good news for Hongzhou at the moment.

Not to mention destroying the Demon Realm teleportation array, but judging from the current strength of the demons in Qingzhou, it is possible to combine the strength of the two states and push the battle line back to Qingzhou.

"Fellow Daoist Chen, go and take a look." Yue Xiying looked at Cao Rui and said.

Cao Rui nodded slightly, moved forward, and at the same time used his spiritual sense to observe the ancient teleportation array here.

The base of the ancient teleportation array here is quite well preserved, but due to its age, many of the magic patterns have lost their effectiveness.

The key to repairing this teleportation array is to restore its array patterns and reactivate it to obtain the teleportation data.

Cao Rui carefully observed the patterns of these teleportation arrays.

They seemed to belong to the fourth-level magic array runes, the fourth level, which was the basic magic array rune level required for ultra-long-distance teleportation.

In terms of the overall refining quality of the teleportation array, it can be regarded as a third-order teleportation array.

However, Cao Rui frowned slightly.

The fourth-order magic array runes on this teleportation array are quite different from the several teleportation magic array runes in his mind.

It is estimated that in the evolution process of the teleportation array runes here, the array runes from level 0 to level 1 are significantly different from the array runes that Cao Rui learned.

With each level upgrade, the monks' transformation and upgrade of runes became more and more drastic. By the fourth level, the gap between the teleportation array and the array knowledge mastered by Cao Rui became larger and larger.

"Fellow Daoist Chen, what do you think?" Yue Xiying saw Cao Rui frowning, and her heart tightened slightly, so she couldn't help but ask.

Cao Rui thought about it and found that the remaining traces of the magic array on the teleportation array could barely be seen, and there were still quite a lot of them left.

Cao Rui was able to rely on the experience beads to forcibly replicate and accumulate experience points, thus upgrading this fourth-order teleportation rune to a perfect level.

As long as you spend enough time, it is not impossible to succeed.

So he replied, "You can give it a try."

Yue Xiying's face lit up: "Fellow Daoist Chen, how are you going to try it? What do you need?"

Cao Rui said, "If possible, please prepare some refining materials for the teleportation array for me."

Naturally, Cao Rui pocketed the materials for refining equipment with justifiable reasons.

Most of the materials for refining the teleportation array obtained from the Tianji Fortress have been consumed.

Cao Rui was still quite distressed as he had just teleported back from Qingzhou and lost a teleportation base.

Although Cao Rui seems to be building teleportation bases everywhere in a prosperous manner, in fact, the refining materials in his storage bag are almost empty.

There were only enough teleportation array bases left to be assembled twice.

Therefore, it is necessary to obtain more refining materials from Hongzhou.

Yue Xiying mistakenly thought that Cao Rui wanted to refine a teleportation array again, so she said, "Fellow Daoist Chen, please tell me what refining materials you need?"

Cao Rui took out a jade slip, wrote down the materials he needed for refining the weapon one by one, and then handed it to Yue Xiying.

"This is just a basic list, it would be better if you could provide a few more."

Cao Rui added.

Yue Xiying nodded to show that she understood: "No problem, I will go and find these materials for you personally."

After saying that, Yue Xiying pulled Bai Luojing up and left the hall together, leaving Cao Rui alone to continue studying and analyzing the teleportation array.

Cao Rui was also a person who didn't like to waste time. He patted his storage bag without hesitation, and then took out a crystal plate obtained from the Tianji Fortress.

The crystal plate that Tianjizi used specifically for practice was very durable, and he still had a lot of it in stock in his storage bag. It was simply the best tool for practicing magic array runes.

Cao Rui found a cushion and sat down cross-legged.

He locked his spiritual consciousness tightly on the ancient teleportation array in front of him and carefully read the magic array runes on it.

These magic array runes all have a confusing function. Even though Cao Rui has a powerful spiritual sense that can cover five hundred miles, he cannot see them completely and can only see a rough outline.

He relied entirely on his own experience and feelings to guess the meaning of these lines.

If one wants to see at a glance the detailed information of the magic array runes engraved by others, one needs to have at least the Jindan stage of cultivation to do so. And perhaps only those legendary gods who have ascended to the spiritual world have such ability.

Cao Rui took a deep breath, concentrated all his energy, and focused all his attention on the magic runes on the teleportation array and the crystal plate in his hand.

His eyes were extremely focused, and there was already a faint glow in them.

His fingers gently touched the crystal plate, feeling its texture and temperature, and then began to carefully carve runes on it.

The first engraving was not successful.

Cao Rui thought for a moment and changed the engraving details of several of the lines.

Although the experimental process is time-consuming, it does not consume much energy.

As long as you can condense experience beads, everything will be easy.

If it really doesn't work, then go to Yunzhou and call baby Tianji over to take a look.

This guy has mastered and understood a large number of magic array runes in his mind, so he should be able to repair the runes here or obtain related transmission data.

......

So, three days later, Yue Xiying returned to the hall with a storage bag.

He walked up to Cao Rui and handed him the storage bag: "Fellow Daoist Chen, I went back to the alliance and collected three sets of the refining materials you requested!"

Three? Cao Rui raised his eyebrows slightly, with a hint of surprise on his face.

He originally only expected to get one portion to make up for Qingzhou's losses, but now there are three portions, which is beyond his expectations.

These refining materials are all precious materials needed to refine the Tianji Teleportation Array, and it is very difficult to obtain them in this era.

But if you think about it, it is understandable. Yue Xiying is the number one formation grandmaster in the alliance and has extensive connections and resources, so it is understandable that he can collect so many copies.

Daoist Chen took the storage bag, scanned it with his spiritual sense, and said sincerely, "Thank you."

Then he put the storage bag into his arms without hesitation.

Yue Xiying was slightly stunned when she saw Cao Rui's actions, but didn't say much.

Yue Xiying looked at the ancient teleportation array which had not changed at all and said, "Fellow Daoist Chen, do you have any clues?"
