==============================================

A piece of decane crystal stone contains hundreds of times the spiritual power of the same volume of decanic water spiritual liquid, and the spiritual power contained in a drop of decanate water spiritual liquid is hundreds of times that of a drop of the same volume of decanic water true yuan, so calculated, a decanate crystal stone ball of such a large decanter contains enough spiritual power to be on par with a master at the peak of the yuan infant, and I can't imagine that even one-tenth of the formation is not lit.

There are a lot of top-grade spirit stones, but at most they are at the same level as spars, and it's not worth wasting them.

The amount of spiritual power required for this formation is outrageous, and the most hateful thing is that the key is not the amount of spiritual power, but the amount of spiritual power that can be provided within the volume of that hedron ball.

Yang Chen tried another method, such as carving the lower part of the decanate crystal stone into a semicircle, which just matched the pit, leaving some extra parts on it. As a result, after putting it on, it seems that this formation can still judge the shape of the spar, and it refuses to activate it. And change to a circle, and you can start again.

I don't know how the Dao Formation did this, Yang Chen has no way for the time being, does he really want to use that dragon ball? It seems that in this world, only the dragon ball can have such a huge supply of spiritual power.

Lu Tian had been quietly watching Yang Chen do the experiment, and he was originally waiting with great interest, but now he was also a little anxious, and began to fly and urge again.

After thinking about it, Yang Chen still couldn't think of a way, what was more spiritual power than the Crystal Stone? Under the urging of Roaring Heaven, Yang Chen had to rack his brains to think.

After thinking about it for a while, Yang Chen still felt that he should see what he had on him, he had received too many things in the recent past, maybe there were some strange things that could provide huge spiritual power.

In the Qiankun bag, there were all things that Yang Chen didn't pay much attention to, and after rummaging through them, there was nothing special. So, Yang Chen began to look for it in the merit vows.

Turning it over in the same way, Yang Chen suddenly found something, and his heart moved, and he took out the thing that was placed in the corner of the merit ring.

It was a walnut-sized ball, glowing blue throughout, and it contained powerful spiritual power. And before rushing to the sea without returning to the sea, Yang Chen also used such a thing many times to drive away some powerful sea beasts, so as not to delay his trip.

This bead is the crystallization of demonic power left before the blue shadow soars. In the final analysis, this is also just a crystallization of spiritual power, but it was condensed by the great demon before the tribulation and ascension, and the spiritual power contained in it is simply incredible, and it will automatically release a powerful coercion, in the ocean, no sea beast dares to meet it head-on.

The old dryad of the demon power crystallization has studied it, and Hou Yun has also studied it. However, after all, it was a sea demon beast, and unlike their cultivation routines, it could give limited help, and Yang Chen's only role in using it was to use it as a pass to the sea.

What is embarrassing is that the blue shadow's demon power crystallization can only be used among the sea clans, and after arriving on land, it has become the object of many demon clans' want to snatch it. Back then, the second city lord of the Banyan Tree Cave Mansion was moved by greed because of this demonic power crystal, and forcibly chased and killed Yang Chen, but was killed by Yang Chen.

In addition to the inappropriate size, it seems that this demonic power crystal fully meets the requirements of containing huge spiritual power. Yang Chen thought about it, took out a piece of decane crystal stone again, and carved it into a spherical shape, but he hollowed out the center of the ball, leaving a passage, stuffed the demonic power crystals into it, and blocked the passage with another suitable spar well, and then the decanic water true technique was activated, gluing the gap between the two decanate crystal stones. ...,

Before Lan Ying ascended, he not only practiced Yang Chen's transformation technique, but also absorbed the decanate water true yuan given by Yang Chen, and among the demonic power crystals left behind, there was a strong aura of decanate water true yuan, which was in the same vein as the decanic crystal stone. This is also the reason why Yang Chen handled it like this.

Holding the treated crystal stone ball, Yang Chen carefully placed it on the pit again in the half of the "Baidu Qihang Text" circle. After putting it away, Yang Chen pushed a few steps away, and together with Roaring Sky, he carefully stared at the changes in the hedron ball.

After a while, it seemed that the hedron ball did not react at all, and the lines on the stone slab showed no sign of brightening.

Looking at this situation, Yang Chen couldn't help but sigh in his heart, it seems that this cheating is not so easy, and people don't recognize it at all.

I can't help but admit that this formation left by the dragon clan is really strong, and he can even judge the shape of the spiritual power source, which is something that Yang Chen has never come into contact with even in the immortal realm. It seems that it is not unreasonable that the dragon clan can always be strong, just by looking at these unique formations.

Since the method of cheating is not good, Yang Chen can still sigh secretly, it has reached this point, but he is blocked from the door and cannot enter, it is really a pity.

But there is no good way at the moment, so I can only return here, and then find a way to get the dragons in the dragon treasure house. It is estimated that the only one that can meet the requirements of this spiritual power source is the Dragon Ball.

Just as he was about to step forward to take back the treated hedron ball, the spar ball suddenly flashed, and then the lines on the slate began to light up again.

Yang Chen's eyes suddenly lit up with these lines, and the treated spar ball actually worked, and he hurriedly flew high at the moment, looking at the range where those patterns lit up.

Roaring Sky was also a little surprised, but this time he didn't fly, but directly coiled on Yang Chen's body, his eyes followed Yang Chen's gaze, staring directly at those lit patterns.

After a while, the pattern has lit up to the range of the last stop, but this time, it did not stop here, but continued to expand outward.

In Yang Chen's heart, there was a burst of nervousness, and the current situation was obviously the crystallization of the blue shadow's demonic power. However, how much stronger this demonic power crystal is than the decanic crystal stone, everything is still unknown. Yang Chen was not afraid of losing the crystallization of demonic power, he was afraid of falling short when he was about to succeed, and that frustration of failure was the great enemy of cultivation.

Under Yang Chen's worries, the patterns on the stone slab lit up all the way, two, three, five, eight, nine, until all the patterns were lit up, without the slightest dim meaning. And the crystal stone ball, still maintaining its original size, was quietly placed on top of the pit.

It was finally done, and Yang Chen's heart finally let go of half of it. The hedron ball has not disappeared yet, which means that there are still magic power crystals left, and they will not all be used up.

Lighting up the pattern is only the first step, and the next step is to launch the formation, but I don't know if the demonic power crystals of the Dao Dao can still hold it...... ）
