Thinking that I had made a mistake, I checked it several times before I was sure that the familiar feeling was real, and Cang Jingyun was on the side, and he had already begun to talk about the long history of this treasure house and the preciousness of the treasures it contained, and I could only pretend to listen calmly to his words if I didn't want him to see my excitement.

"How? Exchange your elixir for the treasure in our treasure trove, this transaction is not a loss, right? ”

Smiling at me proudly, this guy's face was full of "Come and praise me" deep smirk, I skimmed the corner that exuded a familiar atmosphere, and smiled meaningfully: "No loss, no loss." ”

"So ...... cooperation"

Cang Jingyun looked at me expectantly, the two bright eyes emitted a longing light like a begging dog, I didn't intend to refuse, as soon as I came into contact with his eyes, I didn't have the intention of refusing, nodded and said lightly: "It's okay to cooperate, but sometimes your treasure trove doesn't necessarily have what I need, so I'm responsible for providing the elixir, and you need to help me collect what I need within the scope of your authority and ability, so that you can take what you need, what does Team Leader Cang think?" ”

Cang Jingyun was stunned for a moment, and his handsome eyebrows were slightly raised: "Within our authority and ability?" ”

I nodded, he suddenly smiled, and replied cheerfully: "Why can't such a sure-profit deal?" ”

So, I began to pretend to be casual and searched for treasures in the treasure house, picking and choosing for a long time, and finally found my target on the shelf in the far corner - a black box!

That's right, it's the black box. The same style as the two black sunspots in my space bracelet, a black box with the same breath! Even the quaint texture on the surface of the box is exactly the same!

Casually scanning the black box, I picked it up with a pretending of surprise: "How can there be such an unsightly thing in a treasure trove full of glittering treasures?" ”

Cang Jingyun scratched his short black hair, shook his head and said: "You are wrong, this is not something that is not good-looking, not to mention how different its black luster is among the colorful treasures, do you take a closer look at the surface of this box, do you still think it is not good-looking?" ”

I froze, looking carefully at the surface of the box. At first glance, there is no difference. I glanced at Cang Jingyun suspiciously, this guy had a mysterious smile on his face, and frowned secretly, and I secretly unfolded my divine sense and probed into the box. I found that my consciousness couldn't get in at all. It's like you're being blocked out by something.

"Huh?"

Amazement. I tried again and the result was still the same.

I tried to open the box, but it didn't open at all. Just like the box I bought last time on the exchange market of Ruikong Auction House, the surface of this box should also be banned.

However, when I got the last box, I didn't know anything about prohibition, so I could only be opened with the help of Nangong Mo, but now, I have also achieved a little success in the field of prohibition and formation, so there is no reason why I can't see it.

"You finally discovered that the surface of this box is covered with a high-level formation, and even the highest-level formation master existing in the dragon group can't crack it."

"The highest level?"

"Sixth-level formation master."

The ranks of Formation Masters are divided into one to nine, of which Levels 1 to 3 and Rank are called Junior Formation Mages, Levels 4 to 6 are called Formation Masters, and Levels 7 to 9 are called Formation Masters.

I don't know why, in the past few hundred years, there have been very few formation masters on the earth, and even the number of formation masters is pitiful, and the sixth-level formation masters can be regarded as the pinnacle of formation masters.

But even so, this formation master failed to crack the protective formation outside this box, how high should the level of this formation be?

"So, even if I get the box, it's useless, and if I want to get the contents inside, I have to find a formation master above level seven?"

In fact, even if I can easily open this black box and get the things inside, the contents may not be of much use except for the Baifang Ji Book that may appear, after all, the half of the map in my hand is a map of the ancient period of the Firmament Continent, even if I get the second half now, it will be useless at all.

That being said, this box carries my memories of some people, and while I don't want to mention it, those days of training together were really happy, and I don't want to erase them like that.

"I'm the legendary genius, maybe in two days, my formation level will be raised with a bang."

Simply hugged the box tightly in his arms and swore its possession, I smiled and looked at Cang Jingyun who had twitched the corners of his mouth, forgiving him for not turning his face against me because of a box that could not be opened.

"Okay, okay, who made you a beautiful and lovely girl, this box will be given to you, but the pill is ......"

I found the thing I dreamed of, I was in a good mood, and generously patted my chest and promised: "In terms of pills, you can rest assured, I still have a lot of refining materials for the cultivation pill here, and I can provide you with about three bottles on a regular basis, and I still have some other things like retreat and the like, but because those are non-mainstream pills, I haven't collected many materials, so the number will not be too much." ”

After a pause, I said, "However, if you can provide the materials for refining medicine, I will be happy to serve you." ”

After thinking about it, I left one of each of the several elixirs for refining the Cultivation Pill for Cang Jingyun as a reference medicinal material to find spiritual grass or herbs with similar effects, no matter how much my inventory is, it can't withstand a long period of squandering, and the result of sitting on the mountain and eating empty mountains must be that my spiritual grass is exhausted.

This time, both parties were very satisfied, and Cang Jingyun personally sent me out of the research institute, smiling without eyebrows: "Miss Meizi is really the kindest and cutest beauty I have ever seen, do you want to consider being the deputy leader of our fourth group?" ”

I was stunned for a moment, and looked at him like a madman: "You have a really big heart, we have only known each other for a few days and you issued this kind of invitation, in case I am a spy sent by some hostile force to deliberately confuse the public and approach you, you are not playing into the enemy's hands so lightly." ”

Hearing this, Cang Jingyun turned serious, stared at my eyes seriously and asked, "Miss Meizi, are you a spy sent by the enemy?" ”

He rarely showed a serious look, although I knew that this guy was likely to turn into a joke in the next second, I was still infected by him, and shook my head seriously.

Sure enough, in the next second, the leader of the warehouse team turned into a funny warehouse, shook his head and said: "That's not it, the person I Cang Jingyun fancy has made mistakes!" (To be continued......)
