On the merchant ship, Yi Cheng's work is extremely simple, he only needs to take out two or three months every year to refine magic weapons for the psychic trading house.

The rest of the time he is completely free, but this free time is occupied by Meng Hui for most of it, Yi Cheng has no dissatisfaction with this, one of them has theory, the other has experience, but they have learned a lot from each other.

"Are you sure we can refine the nine-rank top-grade magic weapon by doing this?" Meng Hui asked Yi Cheng in disbelief.

"I'm not sure, but I can try, but I don't know how to arrange the Five Saints Rongyuan Array in the Dao, so I can only slowly cultivate the tacit understanding between us, but this time the refining is only the ninth-order top-level, it should be about the same, after all, the difficulty of refining the Ten Cheng Dan is much more difficult than refining the ninth-order top-level magic weapon."

At this time, Yi Cheng had the Five Elements Materials, but the Five Elements Sword Formation could not be used for a long time, the reason was that the quality of the earth-based spirit sword was too high, reaching the top level of the ninth order, while Yi Cheng's other spirit swords were either primary or still a piece of material.

Even if Meng Lao made a move, he could only create a ninth-order high-level.

Although there is only one line of difference between the high-level and the top-level, it is not very large, and Yi Cheng can't bring down the top-level magic weapon, so he can only find a way to upgrade the quality of the other spirit swords to the ninth-order top.

"Theoretically, yes, but this tacit understanding is not so easy to cultivate, even I don't have many ninth-order materials, if we want to cultivate a tacit understanding and accumulate experience, we need a lot of ninth-order materials, well, I'll go find Wuzhou Wuyi, they should still have some inventory!"

The Wu Zhou and Wu Yi mentioned by Meng Lao were the fathers of Wu Wencheng and Wu Wenpeng, respectively, and thought they were the two sons of Wu Changheng, the current president of the firm.

Wu Wencheng is a tomboy, it is estimated that even Meng Lao or Wu Wenpeng don't know about it.

The psychic firm can be said to be the private property of the martial family, and the others are just high-level workers, although the psychic firm has a lot of first-level consummation monks, but the position of the president will only fall on the head of one of the Wuzhou Wuyi.

As for who it is, no one knows now.

However, Wu Zhou and Wuyi are comparable in strength, and their ability to do things is also comparable, and this open and secret battle has been unknown for many thousands of years.

Originally, because Wu Zhou had no heirs, Wu Changheng planned to let his second son Wu Yi inherit the position of president, but more than 10,000 years ago, Wu Zhou suddenly gave birth to a son with a female cultivator, that is, Wu Wencheng.

So this time the situation is even more unclear, which also leads to Wu Wencheng's hostility since he was a child, but Wu Wencheng is extremely talented, in just 13,000 years, he has reached the Mahayana period, and his combat effectiveness is not worse than Wu Wenpeng, who is already in the middle of Mahayana, so more people are optimistic about Wu Wencheng.

The battle between these two pairs of father and son Old Man Zhao did not seem to interfere, obviously to survive the fittest, after all, the psychic business house cannot be handed over to the weak.

Yi Cheng is not interested in taking care of the affairs of the martial arts, but Meng Lao has to go to the two of them to borrow materials, Yi Cheng came out of Kunlun Wonderland, and there are not many other things on his body, but this superb material is a vehicle bucket.

At that time, in the Baishui Tribe, I don't know how many thousands of years of accumulation, Yi Chengcheng didn't refine much in a thousand years.

Because of the limitations of the original level, those ninth-level materials Yi Cheng naturally would not be wasted, so he was openly and secretly greedy for ink, and the patriarch of Baishui didn't say anything, and those things were also decorations in his place.

In addition, Yi Cheng killed Montenegro, as the head of the clan, the best materials on Montenegro are countless, although Yi Cheng has used some over the years, but not even a tenth of it.

When Yi Cheng came up with enough materials to create hundreds of ninth-order magic weapons, Meng Lao was completely shocked, he had only accumulated dozens of materials over the years, where was this Yi Cheng?

What level of refiner is Yi Cheng's master, who has never revealed his name, who would be so rich, he doesn't think that these things are obtained by Yi Cheng with his skills.

With the materials, the two naturally started refining.

But the effect is not ideal, at the beginning, the two had almost no tacit understanding, and the cooperation between the two was not as good as Meng Lao's own refining.

But after wasting more than a dozen materials, they finally made some progress, at least what they refined would not be worse than what Meng Lao himself had refined.

Although it is only a ninth-order advanced level, it has not yet met their requirements, but it will be shocking to take one of them out of the way.

When the hundreds of materials that Yi Cheng took out were all used up, the magic weapon created by the two of them was better than that created by Meng Lao himself.

However, it is still a lot short of the ninth-order top.

And just when Meng Lao was about to go out again to borrow materials, Yi Cheng took out more than three hundred ninth-order materials again.

This time, Meng Lao didn't bother to ask, as long as he could refine a ninth-order top-level magic weapon, it didn't matter where his materials came from.

The two of them almost fell into selfless refining, and even Yi Cheng's internal work was directly pushed away by Meng Lao, and instead used a few ninth-order magic weapons.

In this way, the two of them were like obsessed with each other, cooperating with each other to practice the art of alchemy.

In this process, it can be said that all the skills and experiences of the two have been fully displayed, and the learning between them has also become more in-depth.

For a full seven hundred years, even Yunzhu would not see Yi Cheng more than ten times, although there was some resentment, but there was nothing to be done, so he simply chose to retreat.

And not long after seven hundred years, there were cheers of surprise from the refining room of the two!

"It's successful, it's successful, we've succeeded, hahaha, I really didn't expect that my Meng Hui would refine a ninth-order top-level magic weapon in his lifetime, ha, it's worth dying!" Meng Lao almost cried with joy.

Yi Cheng also let out a long breath, and his seven hundred years of hard work were finally not in vain.

However, Yi Cheng's alchemy at this time was still at the early stage of the ninth order, and he knew that it was no longer experience but divine consciousness and spiritual power that limited him, and if he didn't break through the Mahayana period, he would never be able to advance.

After a short period of joy, the two of them did not stop, nor did they immediately set out to refine Yi Cheng's Five Elements Spirit Sword.

Instead, they continued to work together to create a ninth-order top-level magic weapon like before, and one success was not enough for them to be fully qualified for this job.

For more than two hundred years, Yi Cheng had already taken out one-third of the materials in his storage ring, and the two of them were only now sure of victory, as long as nothing else, every time they cooperated now, they could create a ninth-order top-level treasure.

When three months later, Yi Cheng looked at the five swords in front of him, and couldn't help but feel heartfelt joy.

How many years have passed, and he finally has the Five Elements Spirit Sword again, and the Five Elements Sword Array can finally exert its might.

"Hahaha, congratulations to Brother Xiao, your Five Elements Sword Formation is very powerful!" Meng Lao smiled at Yi Cheng with a radiant expression.

"Thank you Meng Lao for your help, otherwise I don't know what year and month Lu Dao will be able to build this sword array!" Yi Cheng hugged his fist at Meng Lao and thanked him.

"Hehe, what you said, I have to thank you, this is less than a thousand years, but I have created 10,000 ninth-order magic weapons, tsk, this is as much as I have built in my life, with these hundreds of years of experience, I believe that it will not take 10,000 years for me to enter the ninth-order top, and my life's wish is also counted, hahaha"

Meng Lao smiled happily.

"Meng Lao, it is less than a hundred years before the next auction, I also plan to retreat for a period of time, I only leave these two thousand top-level magic weapons for the magic weapons created here, and the rest will be troubled for Meng Lao to help me deal with it, we will get half of the spirit stones, Meng Lao must not refuse!"

"No, the material is yours, so I have accumulated so much experience, how can I still divide your things, no, no!" Meng Lao flatly refused.

"Meng Lao, you and I are also teachers and friends, help each other, you don't want this spirit stone, how can I be embarrassed to accept it all, so let's do it, Sanqi Kai, if Meng Lao refuses again, he will not recognize me as a friend!"

For partners who have cooperated for nearly 1,000 years, Yi Cheng will not hesitate.

"Well, okay, then I'll lick my face and accept it, I'll sell these things separately for a higher price, and I'll let you know before the auction starts!"

Meng Lao saw that Yi Cheng was indeed sincere, so he no longer refused, took the storage ring and left.

And at this moment, the communication jade talisman that Yi Cheng had been paying attention to unexpectedly flashed.

Yi Cheng took it out and looked at it, and his face became weird!
