Bai Yuzhe was excited, but Lei Yue, who said this suggestion, his face fell......

Because, Xuanling Essence Gold is too precious, and the quantity is very rare, even with the foundation of the Tower of Babel, there is not much storage, this thing is also very important for forging high-level weapons.

No matter how big the role is, it is not as important as the current research! Lei Yue could only take out a small piece of Xuanling Essence Gold that he was carrying.

This piece of Xuanling Essence Gold is not much bigger than a thumb, and it looks like Lei Yue is still a little painful.

"It's a little big, isn't this even a hundredth of the entire array less than a percent?" When the dragon girl saw it, she was a little disappointed, and scolded in her heart, this old man is too stingy, right?

In fact, she misunderstood, Lei Yue really only had such a small piece on his body, and if it was according to her assumption, it was estimated that all the Xuanling Essence Gold of the Tower of Babel would not be enough to refine an array plate......

Moreover, just such a small piece of Xuanling Essence Gold, if it is integrated into a high-grade holy weapon, it can be turned into a top-grade holy soldier in Lei Yue's hands, and it is a high-quality kind among weapons of the same level.

"That's enough, Senior Lei, please talk about this piece of Xuanling Essence Gold refining, make it into a small octagonal shape, and integrate it into the middle of the entire array plate. Bai Yuzhe didn't pay attention to the dragon girl, if the entire array was made of Xuanling Essence Gold, then the Tower of Babel would not be able to afford it.

For the entire array, only the part of the place where the brute pattern is carved is enough to use Xuanling Essence Gold, and the rest is auxiliary. In fact, the value of all kinds of metals used in this array has already exceeded the level of the best saint soldiers, and if such a piece of Xuanling Essence Gold is integrated, the value is ......

Lei Yue quickly did what Bai Yuzhe had ordered, and the small piece of Xuanling Essence Gold had become octagonal and integrated into the middle of the array.

Then, Bai Yuzhe began to try again, this time he was particularly careful, because he was going to treat this array plate as a finished product, once it was scrapped, the loss was really not small.

The other three didn't dare to make any noise on the side, for fear of disturbing Bai Yuzhe!

Finally, after nearly seven days of hard work, Bai Yuzhe finally finished everything.

"Quick, two seniors, let's try to see if it's feasible. Bai Yuzhe didn't stop for a moment, and immediately began to do the final test.

Zhao Qin and Lei Yue also had excited looks on their faces, and then quickly left the practice room, and even walked out of the purple bamboo forest, and when they reached a far enough place, they opened the stealth array disk again, and then prepared to come towards the purple bamboo forest one after the other.

They walked very slowly, trying to control all the energy of the stealth array.

And Bai Yuzhe, who was in the practice room, had already placed the array disk in the entrance of the storage room, and then opened a gap, and the light had been adjusted in an instant!

"Senior Lei, you are close to the Purple Bamboo Forest, thirty meters apart! Senior Zhao, you are in the direction of the south side, and there are still more than a hundred meters away from the Purple Bamboo Forest. ”

The two old men were cautiously approaching, and Bai Yuzhe's voice had already come out of it, which immediately stunned Zhao Qin and Lei Yue.

The location where they were located was estimated to be more than a thousand meters away from Bai Yuzhe's practice room, and they were discovered in an instant.

The two of them immediately turned around and walked in opposite directions, they wanted to test how far this array could be.

After Zhao Qin and Lei Yue walked out of forty or fifty thousand meters away from the Purple Bamboo Forest, they turned on the stealth array again, and after controlling their energy, they cautiously walked towards the Purple Bamboo Forest.

When they were about 10,000 meters away from Bai Yuzhe's location, Bai Yuzhe's voice came from inside, and then quickly reported their location.

And these two people couldn't feel how Bai Yuzhe found out at all.

He used the method of sound transmission, otherwise if he shouted out in such a loud voice, I am afraid that many people on the second floor of the Tower of Babel would have discovered it! This array of this study is completely secret, and only the absolute high-level people know about it within the Tower of Heaven.

At such a long distance, it is still a bit difficult for the sound transmission, after all, Bai Yuzhe's realm is there, and if he changes to the normal Tianchong realm, the transmission is estimated to be only a thousand meters at most.

Zhao Qin and Lei Yue's faces showed surprised expressions again, and then quickly turned into surprise!

More than 10,000 meters, that's enough! As long as the person who uses the stealth array disk, he must be cautious, otherwise it will be meaningless, and he will soon be discovered!

Cautiously approached, it was discovered a kilometer away, and the stealth had lost its meaning.

The two of them quickly rushed back, picked up the array plate and observed it carefully, and couldn't put it down!

With just such a array, the materials used in it added up were equivalent to two top-grade holy soldiers! Moreover, in the process of research, more than ten top-grade holy soldiers were wasted!

However, in the eyes of Lei Yue and Zhao Qin, this is completely worth it, this is another historic breakthrough, even if it wastes a lot of materials, it is definitely worth it, and the Tower of Babel can afford to consume!

Soon, the news was notified to the owner of the Tower of Babel and some high-level officials, and the high-level people were shaken, and they were all excited. Originally, although the stealth array was in the hands of the Tower of Babel, after all, some of it was exposed outside.

They are also worried that someone will do evil with a stealth array, or even fall into the hands of cult warriors, and they will be studied and imitated by the other party, so it will be a big trouble!

Now that you have this thing, you don't have to worry about it.

This array disk was quickly named 'Light of Wisdom', and this time the biggest contributor to the research of this array disk, in addition to Bai Yuzhe, was the Dragon Girl.

As for Zhao Qin and Lei Yue, they actually went to learn, even if Lei Yue's later proposal was actually just to let the light of wisdom come out a little earlier, and Bai Yuzhe himself would be able to think of it sooner or later.

For this, the Tower of Babel wants to give the dragon girl a huge reward, but the dragon girl refuses. She grew up in the Holy Land of the Ancient Barbarians, and she was also the darling of the Temple, with a high vision and a very wealthy person.

Although there are many things in the Tower of Babel that she does not have, the Dragon Maiden has chosen to leave a good impression on the Tower of Babel.

This made Bai Yuzhe also amazed, he didn't expect that the dragon girl, a little girl who didn't seem to have grown up, could still have such thoughts and trade-offs.

As for Bai Yuzhe's merits, Babel didn't want to say anything more, and finally announced that if Bai Yuzhe went to the Hall of Merit to exchange treasures in the future, the contribution points deducted would be halved on the basis of the cabinet.

"Master, can I go out now?" In the purple bamboo forest, Shen Hongyu, Long Hanhai, Zhao Qin, Lei Yue and others were all there, and Bai Yuzhe made this request again.
