I can gather experience beads

"Break the experience bead for me!" With Cao Rui's loud shout, the purple torrent in the experience bead surged up like a wild horse running out of control, rushing madly into his mind.

In an instant, the experience and skills of engraving the fourth-level teleportation array countless times entered Cao Rui's memory like a tide, as if these experiences were all experienced by him personally.

At this moment, the experience bead that originally emitted a bright light turned back into pitch black.

After a moment, Cao Rui's eyes flickered slightly, revealing a hint of satisfaction. He had successfully mastered the fourth-order teleportation array.

Then, Cao Rui picked up the crystal plate again, took a deep breath, and then concentrated his mind and began to engrave the magic circle.

This time, when he once again faced those complicated and complex array runes, he no longer felt at a loss as before. Instead, he easily condensed and engraved all the runes in one breath.

"Very good talent." In mid-air, the rune shadow exclaimed, and then he turned into a human shadow again, with his hands behind his back, looking at Cao Rui below.

"Then, let's start the second and final lesson. We will simply refine the teleportation array base and build a complete teleportation array." The rune shadow said in a deep voice: "You have ten days to refine the base and build a complete teleportation array."

As he spoke, a soft light appeared in the hand of the rune shadow, through which some complex rune structures and lines could be vaguely seen.

"This is the information on the technique of building the base of the teleportation array." The rune shadow waved his hand lightly, and the ball of light turned into a stream of light, quickly rushing towards Cao Rui.

Cao Rui stretched out his hand to catch the stream of light, and saw a jade slip in his hand.

shhhhh!

Two more streams of light flew out from the rune shadow's hand and landed accurately in front of Cao Rui.

One of the streaks of light dissipated, revealing a refining furnace emitting spiritual light. Upon closer inspection, it was actually a third-order refining furnace!

One was a storage bag. After probing with his spiritual sense, he saw that it contained all the materials needed to make the base of the teleportation array.

"First, look at the refining information of the teleportation array."

Cao Rui's spiritual consciousness read the information in the jade slip.

The teleportation array base is the most basic thing in a teleportation array.

The base can be refined in any size and can be changed according to the distance and purpose of the teleportation array.

Because the base of the teleportation array is very large.

Therefore, the base is usually divided into several parts for refining, and then assembled after successful refining.

The teleportation rune can be engraved after being refined on the base.

But Cao Rui had already mastered the art of casting spiritual patterns, and he engraved the array runes on the base at the same time when he was refining it.

The quality of the base of a teleportation array is at least that of a second-level magical tool.

The teleportation array base required in the jade slip is also of second-grade quality.

The distance that can be transmitted is within a range of 100,000 miles, which can almost cover half of Yunzhou.

Cao Rui looked at the glowing third-level refining furnace in front of him, and then looked at the shadow in the sky: "If I pass this level, will this refining furnace belong to me?"

"It's yours." The shadow swayed for a moment and spoke.

Cao Rui nodded slightly, waved his hand to summon the refining furnace, and after getting familiar with it, he condensed his magic power into it and started a spiritual fire.

When it comes to refining equipment, Cao Rui is really good at it.

Figure out the refining part and divide the second-order teleportation array base into four parts for refining.

Cao Rui used the Spirit Pattern Casting Source Technique.

Cao Rui put pieces of ore into the refining furnace and slowly smelted them together.

"Then there is the engraving of the magic circle..."

During the smelting process, Cao Rui engraved a fourth-order magic array on it.

Soon, a fourth-order magic array was engraved.

One quarter of a second-level base can only be engraved with a fourth-level magic array. If there are more, the material of the base will not be able to bear it.

"One quarter, done!"

Cao Rui took out a quarter of the base from the refining furnace and breathed a sigh of relief.

With the help of the Lingyin Jade Pendant and the Experience Beads, his weapon-refining skills have surpassed Wu Qingxuan's.

At this time, refining the second-level teleportation array base seemed extremely easy.

"continue!"

Cao Rui took out the materials from the storage bag and continued to refine the rest of the teleportation array base.

In addition to engraving the magic array, you also have to make sure the gaps between the four teleportation array bases are perfect enough.

After all, this is a teleportation array that can span the void. If something goes wrong and it is damaged during transmission, the consequences will be disastrous.

If the person being teleported is sucked into the void, then he is truly doomed.

Therefore, the refining of the teleportation array must be foolproof, and the teleportation array itself must be inspected and maintained regularly.

This was also the first time for Cao Rui to refine this type of combined spiritual tool, so he naturally focused and was extra careful.

The second one, the third one... As time passed, beads of sweat gradually appeared on Cao Rui's forehead.

Finally, the fourth teleportation array base was successfully refined.

Cao Rui took a deep breath, smiled gently, and took a short rest.

The next step is the final step - connecting the four teleportation array bases together.

Each teleportation array base is more than one meter high and very heavy. Cao Rui's spiritual sense and object control skills are unable to drive it. Fortunately, with Cao Rui's current strong physique, it is still very easy to move them.

"Then comes the last step..." Cao Rui used the Spirit Pattern Casting Source Technique to condense the spiritual fire and began to perform the final processing on the gap.

The four teleportation array bases connected together are four or five meters wide, so they naturally cannot be placed in the refining furnace for refining.

Fortunately, the main body of the teleportation array has been refined to perfection.

After several hours, Cao Rui successfully processed the gap connection.

Buzz! The entire teleportation array base suddenly flashed with rays of light.

"Each teleportation array leaves behind unique parameters."

"Set up the teleportation array base here."

"I am refining a teleportation array. After setting the corresponding parameters, I can carry out the teleportation." Cao Rui refined the teleportation array and immediately understood the principle of the teleportation array.

The phantom in the air swayed slightly and circled around the base of the teleportation array refined by Cao Rui.

Then he said, "Good, you have successfully passed this level."

"This is your reward for clearing the level."

A stream of light shot towards Cao Rui.

Cao Rui waved his hand to receive the stream of light, inside of which was a jade slip. The name of the jade slip was [The Ceremony of Transmitting Heavenly Secrets].

Cao Rui took a quick look at it.

It turned out that this jade slip was written by Tianjizi and contained all his understanding and innovations about the teleportation array.

The fifth-order teleportation array rune created by him! There are third-order, fourth-order, and fifth-order teleportation array base refining plans!

Some of the knowledge inside is also very unique.

There are instructions for monks on how to set up 'random teleportation'.

There are instructions for monks on how to set up the 'trigger mechanism for teleportation'.

The monks were taught how to set up a 'one-way teleportation', and the teleportation array would self-destruct after the teleportation was completed.

They are all simple ways of utilizing magic arrays, but Tianjizi has made great use of them.

However, for Cao Rui, this knowledge is extremely valuable, and the most important thing is that this knowledge is important knowledge that can be mastered in a short time.
