The jade cylinder in Li Changqing's hand was the reward for helping Xiong Keshan repair the fifth-order array: the Five Extremes Ten Thousand Thunder Array.

That Yu Yunzhen was also very fast, yesterday after Lian Chenglin left, he immediately steered the treasure ship to sail away, and handed over the promised reward to everyone.

The storage bags for Li Qingyang and Li Xuangang are nothing unusual, they are just a large amount of spirit stones.

But in the fifth uncle's reward, there were not only some third-order formation materials, but also a jade cylinder with a fourth-order formation diagram.

......

And Li Xuangang saw that the fifth uncle Li Changqing's expression was different, and he thought that there was something wrong with the formation diagram of the fourth-order formation, so he asked like this.

Although Li Qingyang, who was sitting next to him, did not exit, he also looked at Li Changqing, and he probably guessed this in his heart.

Being watched by the two, Li Changqing played with the quaint jade tube in his hand for a moment, and then spoke:

"There's nothing wrong with this formation, but ...... It's not of any use for the time being?"

Li Qingyang let out a soft "huh" when he heard this, and he was a little puzzled.

So Li Changqing continued:

"In this jade cylinder that Yu Yunzhen gave me, there is a fourth-order magic array called the Nine Spirit Disc Dragon Array. This is a defensive circle, but if you expand the range...... It can also be used as a mountain guard. ”

Hearing this, Li Xuangang thought of the family's Taiqiu Mountain's current mountain guarding array, which was nothing more than a third-order magic array.

If it was really as the fifth uncle said, it would undoubtedly be better to replace it with this fourth-order Nine Spirit Disc Dragon Array.

However, he thought of the fifth uncle's words that this magic circle was temporarily useless, so he did not question it, but continued to wait for Li Changqing's answer.

Li Changqing turned over his hand and put the ancient jade tube into the storage bag, and then said:

"Although the grade and defense of this Nine Spirit Disc Dragon Array are better than the family's current mountain guarding array, it ...... The conditions are a bit harsh. ”

"Hmm...... To be precise, there are too many resources to be consumed. ”

Immediately, Li Changqing roughly told the two of them about the conditions needed to arrange the Nine Spirit Disc Dragon Array.

After listening, Li Xuangang and Li Qingyang suddenly realized!

It turned out that the layout conditions of this fourth-order magic circle were extremely harsh, that is, its nine array bases had to be built on nine spiritual veins of the same grade.

For the Li family of Taiqiu Mountain, although around the main peak of Taiqiu Mountain, there are indeed nine side peaks that can be used as the layout point of the formation base.

However, there is only the first side peak: "Dan Peak", and the second side peak: "Linghu Peak" each has a spiritual vein, while the remaining seven side peaks have no spiritual veins, just wild land.

This also means that if the Li family of Taiqiu Mountain wants to arrange this Nine Spirit Panlong Array with a grade as high as the fourth order, they must first find seven spiritual veins that have reached at least the second order outside and the lower grade.

Then arrange the seven spirit shifting arrays, and transfer these seven spirit veins to the remaining seven side peaks.

Regardless of whether or not they could find at least seven second-order spirit veins outside, the resources required to deploy the seven Spirit Shifting Arrays alone were a huge number.

Moreover, this is not counting the resources required to deploy the Nine Spirit Disc Dragon Array itself.

Although Li Changqing and the three of them had obtained a total of more than 1.3 million spirit stones during their trip, those were all of special use and could not be spent on arranging such a large array.

Li Qingyang and Li Xuangang were silent, and after thinking about the current situation of the family seriously, they found that as the patriarch Li Changqing said, this array was of no practical use to Taiqiu Mountain for the time being.

However, it only took a moment for their low mood to disappear, this Nine Spirit Disc Dragon Array was just an unexpected joy, even if it couldn't be arranged now, in a few years, the family would have a surplus of spirit stones, maybe they could start to set up the formation.

Besides, the existence of such a fourth-order magic array is an accumulation of heritage for the family.

Therefore, the three of them soon put aside the matter of the Nine Spirit Disc Dragon Array for the time being, and turned to other matters.

......

And the first thing they discussed was the situation they were in.

The resources they obtained during this trip were extremely important for the next development of the family, so how to return to Taiqiu Mountain was the one thing the three of them were most concerned about now.

However, listening to the meaning of Lian Chenglin, it seems that there are still some plans that have not been completed before the return trip.

Li Xuangang then opened his mouth to express his doubts:

"On this trip to the Ten Thousand Star Islands, that Lian Chenglin should not only be just to slaughter the three first-grade fifth-order mid-grade Jiao, there must be other plans, otherwise there is no need for him to bring so many low-level monks here, and he also let our group of foundation building period monks explore freely in the archipelago for half a year. ”

Li Qingyang nodded, agreeing with this, and he also spoke:

"Then could he be coming for that fifth-order spirit vein?"

Li Changqing and Li Xuangang were both stunned, and they realized this problem at once.

The value of a fifth-order spirit vein is immeasurable, and this is not a heaven and earth wonder that can be measured with spirit stones.

This is especially true for the Primal Infant Monks.

Because the spirit veins below the fifth order can be obtained through the spirit vein promotion array, as long as there are enough spirit stones, the spirit vein upgrade will definitely be successful.

But when the spiritual vein entered the fifth order from the fourth-order upper grade to the fifth-order lower grade, there was a change.

Even if you prepare enough spirit stones and a perfect spirit vein promotion array, the spirit vein may not be able to successfully enter the fifth order.

Once it fails, not only will the spirit vein itself be damaged, but also the huge spirit stone resources consumed will also be in vain.

Judging from tens of thousands of years of experience, in the entire eastern part of the Chaoyang Continent, no force has ever succeeded in entering a fourth-order spiritual vein through the Ascending Great Array.

But...... It is rumored that there are successful examples in the middle of the Chaoyang Continent.

And this shows that there is a certain chance of success if a fifth-order spiritual vein is artificially created by a monk, but this success rate is extremely low, so low that no one dares to try it easily.

Because the price of one attempt was too great, the number of spirit stones required for a fourth-order high-grade spirit vein to ascend to a fifth-order lower grade was a terrifying number.

Since he thought of this, Li Xuangang simply calculated in his heart silently:

"Back then, the spiritual veins of Taiqiu Mountain were promoted from the second-order upper grade to the third-order lower grade, and a total of more than 113,000 spirit stones were spent. ”

"And it took about 220,000 spirit stones to upgrade from the third-order lower grade to the middle grade, and about 450,000 spirit stones to ascend to the upper grade......

Although considering that the state of each spirit vein is different, and the number of spirit stones required for each upgrade will fluctuate, he still calculated an approximation.

"If your family wants to exchange for a chance to get a fifth-order spirit vein, you need to prepare at least seven and two million spirit stones on Taiqiu Mountain, and even more for insurance. ”

This is undoubtedly an astronomical amount, even if the situation of each spirit vein is different, the number of spirit stones required to advance to the fifth order will not be too different.

When the spirit veins in other places are upgraded to the fifth order, the consumption will be around 7.2 million spirit stones!

......

It was because it was basically impossible to obtain a fifth-order spiritual vein through the spiritual vein promotion array, so if you wanted to obtain a fifth-order spiritual vein, you could only look for the fifth-order spiritual vein naturally generated between heaven and earth.

At the beginning, after the Great Elder Xun Jinyuan entered the Yuanying realm, the Ghoul Sect couldn't wait to launch a big battle against the demon beasts of the Hengduan Mountain Range, and it was precisely for this reason.

Li Xuangang also learned afterwards that the Ghoul Sect had previously tried to upgrade the original fourth-order high-grade spirit vein of his mountain gate to the fifth order, but unsurprisingly, they failed, losing at least 7.2 million lower-grade spirit stones.

Even a sect like the Ghoul Sect couldn't bear such a loss again, so they had been planning for a long time and spent a huge price to snatch a fifth-order spirit vein from the hands of a fifth-order demon king.

Thinking about it this way, it is also normal for Lian Chenglin, who is also a fifth-order cultivator, to launch this large-scale action for the sake of such a fifth-order spiritual vein.

......

Thinking of this, Li Xuangang looked at the fifth uncle, and after listening to the second uncle Li Qingyang's story, the latter thought about it for a while, and then spoke:

"What Qing Yang said is not unreasonable, the attraction of a fifth-order spiritual vein is enough. ”

"But...... The problem that Xuan Gang said before still hasn't been explained, there is no need for Lian Chenglin to bring so many monks here, and there is no need for them to explore freely for half a year. ”

"It should ...... Whether it was killing Ao San or getting that fifth-order spirit vein, it was only one step in Lian Chenglin's plan, and he should have the ultimate plan. ”

The three of them were silent, thinking for a while, but they didn't come up with what Lian Chenglin wanted to do?

It's just that I vaguely feel that it has something to do with the creation he mentioned earlier!

In this suspicion of the three of them, half a month passed quickly.

At this time, the treasure ship has approached the outermost part of the Wanxing Islands!
