He Xuan saw Lu Qing'an staring at the formation materials and said with a smile, "From now on, you can come here every day and exchange various materials according to the price given by the formation spirit Xiaolu. Of course, there is a limit on the number of times you can come here, and you can't exchange more than three items per day."

Lu Qing'an's eyes fell on the three large formation gems at this time, and an idea popped up in his mind.

It was a pity that he gave all the tenth-grade five-colored formation stone he had just obtained to Tu Zhengxing. In the future, he could use this level of formation stone to arrange some formation patterns that required powerful formation stones to be engraved. A little use of it could be equivalent to a huge formation gem.

Moreover, with this five-colored array stone, he can make various arrays more compact. For example, if the main station of the teleportation array base station uses some of this five-colored array stone as the main core array, the size can be reduced to the size of a fist.

If you work hard to set up the formation, you can even make the formation base station smaller. It can be small enough that it can be disguised as a stone. No need to buy a cave wherever you go. You can just throw it into the mountain to bury the formation base station.

So, he decided to give Tu Zhengxing only one-third, and use the formation gems he would exchange here later to supplement the rest.

If you just exchange three pieces at a time, it shouldn't cost many immortal stones.

"Okay." Lu Qing'an replied with a smile.

"Come, I'll give you an identity token first. You must keep it safe and don't throw it away."

He Hong walked to the center of the tenth floor, where there was an altar with a stone pillar supporting a small platform.

This is actually a formation.

Under He Hong's driving of the spiritual energy, the formation was activated, and then bursts of golden light flashed in the formation. The light gathered above the small platform, forming a palm-sized golden token.

He Hong controlled the formation and engraved Lu Qing'an's name on the golden token.

Afterwards, He Hong took out his identity token, which was also of the same golden color. As he input his immortal energy into it, a faint golden light bloomed on it, which was very dazzling and beautiful.

"Old guys, send the secret key of the formation pattern."

As soon as he finished speaking, the next moment, array patterns floated out from his identity token. They were all complex and unique array patterns.

Lu Qing'an watched quietly from the side, still a little confused about He Hong's behavior at the moment.

These array patterns should have been passed down by the top array masters before, so what are they used for?

He Heng stretched out his hand and pointed at the identity token with Lu Qingan's name written on it, which was still floating on the platform. The next moment, eleven special small formation light screens appeared in front of the platform, like tiny purple bubbles, but giving people an indestructible sense of contrast.

These small purple bubbles are arranged from left to right, and a name appears on each bubble, which corresponds to the names of top members such as He Hong!

Afterwards, as He Hong drew the array patterns on his identity token, these array patterns flashed towards the corresponding bubbles at an extremely fast speed, like a needle, directly piercing the corresponding bubbles, making a puffing sound.

Every time a bubble bursts, the identity token will shine with golden light, as if layers of seals have been released.

When Lu Qing'an saw this, he understood.

Similar to opening permissions, if this identity token is just an identity token, it is almost unusable, or in other words, it cannot be used to use the rights and interests mentioned by the gray-robed old man earlier. But with the permissions opened by these eleven top formation masters, you can have complete permissions!

only.

Just when He Hong and Lu Qing'an thought that the matter would soon be over, something happened that made them both frown.

The last array pattern actually failed to break the last bubble!

"Hmm?" He Heng frowned, looked at the name of the person who had just received the message from the formation pattern, and was speechless for a moment.

Wu Jin!

This old guy is still doing this kind of thing at this time!

He Heng took his identity token and said in a voice transmission, "Old Wu, the array pattern is wrong."

"Wrong? Wait, I kind of forgot about it after I went to revise it last time. As people get older, their memory tends to be bad. Give me some time, I'll think about it carefully." Not long after, Wu Jin's voice sounded from the token.

Hearing Wu Jin's words, He Heng shook his head.

Even a fool can tell what this old man is doing.

I was angry before, but had no place to vent it, so I vented it here!

This old guy has lived to this age but still hasn't figured it out.

He Heng looked at Lu Qing'an and said, "Don't worry about that old guy. You can go over there and see if there is anything you want to exchange. Ask Xiaolu how many immortal stones he needs. After I prepare your identity token, you can exchange it directly with immortal stones. If you don't have many immortal stones, I have some and I can lend them to you first."

Lu Qing'an nodded and said nothing.

Today, Wu Jin obviously had a lot of grievances against him. It might be related to Chen Changsheng, or it might be related to Wu Yaoyang, or more likely it was related to face.

No matter what the situation was, he remembered the other party's actions.

Lu Qing'an began to look for a suitable formation gem, and Liu Lingxuan quickly followed, and then told Lu Qing'an everything Wu Jin said and did when Lu Qing'an entered the formation to test it.

After hearing this, Lu Qing'an sneered in his heart. This behavior was mainly because he couldn't get over the loss of face before, so he acted like this to vent his anger.

To be honest, this kind of behavior is very childish. It can be seen that this person is still a giant baby after living for so long, which illustrates the saying "like father, like grandson".

Chen Changsheng also walked over at this time and said, "Friend Wudao, Elder He has already contacted him and has also discussed this matter with other seniors. It shouldn't take too long. He has always been like this. Because I am more talented than Wu Yaoyang and there is also competition, I have been targeted by him many times."
