In less than five minutes, Lu Chen had already successfully engraved the Innate Spirit Gathering Array in this Dushan Jade Ping'an Buckle.

This piece of peace buckle is a high-grade Dushan jade, with an excellent texture and almost no flaws.

Theoretically, there is no problem at all in engraving the two formations.

However, if he wanted to fuse the two formations with each other and become one, Lu Chen was not too sure.

To put it bluntly, he's just ready to give it a try.

After all, after condensing two merit beads in a row, the merit power in Lu Chen's body has also made a lot of progress.

The first innate spirit gathering array was not difficult for Lu Chen at all now, and it could be said to be done in one go.

Next, he was ready to try the second refining.

However, this time, for the sake of insurance, Lu Chen directly chose the Innate Spirit Gathering Array.

Because the two formations are completely identical, the repulsion between each other is of course the least, and it is naturally the easiest to fuse.

Of course, the reason why I chose this piece of Dushan jade is also to be mentally prepared for failure.

At that time, Lu Chen said that he only needed to consider the texture of the jade, and did not care about the value.

Therefore, among this batch of various semi-finished jade pieces, there are relatively many such as Dushan jade and Xiuyan jade.

It's really because these jades are not particularly favored by the market, but they are also very valuable in the eyes of people in the Xuanmen.

Therefore, in Murong Danfeng's collection, there are naturally a lot of them.

Lu Chen concentrated his energy, urged his spiritual power to the maximum, and followed the operation law of the second innate spirit gathering array to attract the true qi in his body that was wrapped in the power of merit.

With the experience of engraving the second castrated version of the Vajra Body Protection Formation tonight, this engraved second innate spirit gathering array is naturally not a problem.

Even so, Lu Chen still took some time.

Nearly twenty minutes later, the engraving of the second Innate Spirit Gathering Array was finally completed.

But Lu Chen knew very well in his heart that under the isolation of the power of merit, this step was actually not too difficult.

The most important thing is to let the two formations coexist harmoniously and complement each other, so as to achieve the effect that one plus one is greater than two.

Click!

Just a minute later, there was a cracking sound, and the Dushan Jade Ping'an buckle was directly split into two.

Although there was no violent explosion, Lu Chen knew that his attempt had failed.

However, he did not get nothing.

Just now, when the merit power that blocked the two innate spirit gathering arrays was withdrawn, if the speed was a little slower, it might be avoided.

Without hesitation, Lu Chen chose another piece of Dushan jade Ping'an buckle with almost identical texture......

Sure enough, this time, after learning from the experience of the previous time, it took less than half an hour in total, and a compound jade talisman with two innate spirit gathering arrays appeared in Lu Chen's palm.

Feeling this composite innate spirit gathering talisman, the corners of Lu Chen's mouth hooked up a satisfied smile.

In terms of the effect of gathering aura, this innate spirit gathering talisman is more than three times the original.

After putting away this piece of safety buckle, Lu Chen took out another piece of Dushan jade safety buckle.

This time, he was going to try the two Immovable Ming King Formations first......

Luckily, although there was a little accident when it was fused, there was finally no danger, and I successfully got a composite Fudo Ming King Talisman.

After summarizing the first three formation compounds, when Lu Chen opened his eyes again, he directly took out the fourth Dushan Jade Ping'an buckle.

This one is a little more pure than the previous three.

After all, the purer it is, the better the conductivity of the spiritual power will inevitably be, and it will naturally be easier for the two different formations to fuse.

Taking a deep breath, Lu Chen began the fourth refining ......

After a full hour, Lu Chen wiped the beads of sweat from his forehead.

He looked at the still shining peace buckle in front of him with relief, and a tired but satisfied smile appeared on his face.

The peace buckle in front of him already has two formations: the Immovable Ming King Formation and the Innate Spirit Gathering Formation.

Although the strength of the two is different from each other, after being connected by compounding, the spiritual power resonance between the two formations can be formed.

The power of the formation in it has produced a significant increase.

Although it did not show an effect similar to geometric growth like the superposition of the same formation that had been refined before, it was just as obvious.

The richness of the aura and the effect of calming the mind and calming the mind have reached at least 1.5 times that of the original.

What's more, when two different formations are engraved in the same jade talisman, when they act at the same time, the effects that can be produced can be used in a wider range.

Lu Chen faintly felt that the reason why the little fox taught him the refining of the three formations must have a deep consideration.

Through repeated refining during this period of time, Lu Chen found that the Innate Spirit Gathering Formation and the Immovable Ming King Formation were simply like a match made in heaven.

The two cooperate with each other and complement each other, and constantly absorb the aura when concentrating and calming the qi, which will inevitably have the effect of getting twice the result with half the effort.

Of course, the purpose of the little fox is self-evident, even if there are other deep meanings, Lu Chen has no heart to delve into it for the time being.

While staring at the Ping An Buckle, Lu Chen couldn't help but think of his parents who were trapped in the Liangyi Formation.

Lu Chen's thirst for strength became stronger and stronger.

At this moment, Lu Chen suddenly felt that the rune array arranged with the Innate Spirit Gathering Rune around him trembled slightly.

The next moment, the little fox, who had been concentrating on cultivation in merit, suddenly turned into a streamer of light and sprang out, standing on Lu Chen's shoulder.

Almost at the same moment, a white shadow suddenly appeared in front of Lu Chen.

The speed is so fast, even with Lu Chen's current strength, he can't react at all.

Before Lu Chen could speak, the old man had already hugged his fists towards him, and said with a smile:

"Nangong Taixing, the old Nangong family, took the liberty to visit, and I hope that the little brother Haihan!"

"I don't know which master the little brother is, just now there is a lot of fluctuation here, isn't he refining jade talismans?"

Nangong Taixing said as he spoke, suddenly his eyes turned grim, and he slashed at Lu Chen with a palm.

Feeling the oncoming strong wind, Lu Chen didn't have time to make any moves, and the vajra talisman on his body instantly exploded, facing his attack.

At the same time, the little fox, which had been preparing for a long time, also moved.

Originally, because of the power of the Vajra talisman that suddenly erupted, a trace of consternation flashed in Nangong Taixing's eyes.

Now that the little fox suddenly made a move without reservation, Nangong Taixing didn't care about anything else, and hurriedly retreated.

His hands were constantly changing at the same time, forming hand seals, and the violent true qi in front of him was agitated, forming layers of barriers.

However, even the defensive barriers of these Xuan Rank were like paper paste, all of which were broken by the little fox.

Poof-

As his chest was hit by the white light, Nangong Taixing spurted out a mouthful of old blood.

His eyes widened incredulously, looking directly at the little fox in the void, and he spit out a few words with difficulty.

"Nine-Tailed Demon Fox ......"

Lu Chen was equally stunned.

All along, he thought that others couldn't see the little fox at all.

Unexpectedly, it can not only show its body now, but even save itself at a critical moment......
