Soon, Bai Yuzhe came back from outside, looking resolute, and pulled the dragon girl in.

"Bai Yuzhe, what are you doing? What formation you have studied is too profound, where is my level enough!"

When there are other people, she directly calls Bai Yuzhe's name, and she doesn't want people to know about the relationship between master and apprentice for the time being! In fact, there is no appearance of master and apprentice between the two of them.

Zhao Qin and Lei Yue were also inexplicable at the same time, they knew that this little girl was the dragon bloodline of the ancient barbarians, but the ancient barbarians' attainments in formation had no way to compare with the human race, what could she help?

Bai Yuzhe ignored them, and after pulling the dragon girl in, he immediately said impatiently: "Dragon girl, quick, help me carve the brute patterns representing light on these metals." ”

"What?barbarian pattern?" Zhao Qin and Lei Yue were surprised again, of course he had heard of this thing, and he also knew that the human race could not learn the brute pattern, but he had never heard of it, the ancient barbarian race could unite the brute pattern and the formation together?

It seems that the brute pattern can only be used for casting, and the weapons refined by the ancient barbarians also have formation assistance, but the two are separated.

"Do you want to connect the brute pattern and the formation combination? This is impossible, right?" The dragon girl also immediately realized Bai Yuzhe's thoughts, but she still followed Bai Yuzhe's instructions and began to carve brute patterns on the pieces of metal, one on each piece of metal.

And Bai Yuzhe himself is also acting, in the realm of brute lines, he is not as good as the dragon girl. Although the Bull Demon Sage praised Bai Yuzhe as a genius in this regard, and he studied harder, he was still not as good as this proud woman of the sky.

Half a day passed, and the two of them carved a total of twenty pieces of metal to represent the barbaric pattern of light. Then Bai Yuzhe simply let the dragon girl leave, but the dragon girl was also interested at this time, and refused to leave.

If Bai Yuzhe can combine the formation and the brute pattern, it will be a huge breakthrough.

In the following time, there were various attempts, and pieces of metal were carved into various formations by Bai Yuzhe, and then they were turned into scrap iron.

But he was not discouraged and continued to try. Others think that there is no way to combine the formation pattern and the brute pattern, and even the human race can't even learn the brute pattern, but although the ancient barbarian can learn the formation, the talent in this area is very different from that of the human race.

But Bai Yuzhe has never felt so, there must be a reason why he can learn brute lines, he estimates that it may be the role of "Dragon Breaking Nine Heavenly Formula", or "Yantian Array Collection".

Moreover, in the "Yantian Formation Collection", although there is no mention of brute lines, the appearance and function of some formation patterns behind it are somewhat similar to brute patterns.

That's why he was interested in learning brute patterns in the first place, and felt that he might have this opportunity to merge the two.

Five days later, all the metal engraved with the rays of light was destroyed, but Bai Yuzhe still did not give up and let the dragon girl continue to carve.

In his current state, he looks a little crazy, completely related to this array of research, if he doesn't overcome it, it is estimated that he will not think about other things.

Half a day later, Bai Yuzhe began to conduct research......

Finally, after destroying another twenty or so pieces of metal, the brute pattern representing light began to glow brightly......

In the middle of a piece of metal with a diameter of 50 centimeters and an octagonal shape, there is a brute pattern representing light, and the periphery of the brute pattern is full of dense patterns, almost all over the entire metal block, and even some of the patterns are directly connected to the brute pattern.

At this time, the brute pattern was emitting a soft light, illuminating the slightly dim practice room.

"Bai Yuzhe, have you succeeded? Is this true? The brute pattern can play a role in the unexpected place of the weapon?" Seeing this scene, the dragon girl suddenly exclaimed, and a pair of beautiful eyes looked at the fast metal for a moment.

Zhao Qin and Lei Yue were also surprised, after these days of research, both of them felt that there was no way to complete this project, but they didn't expect Bai Yuzhe to have a whim and get out all the brute lines.

After a few days of tossing, I was able to make this brute pattern shine!

You must know that even on the side of the ancient barbarians, the brute pattern can only be used on weapons.

This brute pattern representing light can shine, does it mean that this thing can be done?

"Don't worry, this is just a preliminary completion of an idea, if you want to refine this array plate well, there are still many problems to overcome!" Bai Yuzhe had a smile on his face, although his image at this time looked very sloppy, but his eyes exuded an unprecedented light.

At the very least, if this first step is taken, then there is a great hope of success in the future!

Then, Bai Yuzhe directly threw this piece of metal aside, took out a piece of metal engraved with brute patterns again, and re-carved the formation pattern! After all, that piece of metal only successfully connected the brute pattern and the formation pattern, but the formation pattern on the side was already messed up, and he couldn't make other attempts.

Three days later, a new piece of metal was held in Bai Yuzhe's hand, which was the third after the successful combination of Brute Pattern, and two more were scrapped halfway. At this time, he was adjusting the light, flickering on and off, and he could adjust it with his own source power.

After all, in the early morning, daytime, dusk, and night, the brightness and darkness of the light are not the same, and since it is necessary to make it impossible for the top powerhouses to detect, then it is necessary to completely integrate into the natural light.

After a while, the array disk in Bai Yuzhe's hand had merged with the light in the practice room, and he couldn't see it at all.

Next, it's time to study how to make this light able to break the stealth illusion array. In fact, you don't need to really crack it, you just need to perceive that hidden energy.

But this is indeed a real problem, Bai Yuzhe has been tossing for more than a month, but there is still no progress. Now he was able to perfectly combine the formation pattern with the brute pattern of the light, but he couldn't overcome the last problem.

"Can you use Xuanling Essence Gold as the formation material, and then use a special formation pattern to cover up that weak spiritual power?" Everyone was thinking and meditating, and Lei Yue suddenly said an idea that suddenly popped into his mind.

"Yes, you can try! Quick, bring the Xuanling Essence Gold. When Bai Yuzhe heard this, his eyes suddenly lit up, his knowledge of metals was far inferior to Lei Yue.

Xuanling Essence Gold contains a kind of spiritual power in itself, although it is relatively weak, but if it can be used well, it can really be able to see through the stealth array, Bai Yuzhe was suddenly excited!
