It only took less than a minute for Ash to rush to the credit exchange office with Li Changsheng.

When Ash rushed in, all the people in the credit exchange office were startled, there was no way, a fierce six-meter-long savage saber-toothed tiger rushed into the credit exchange office in an almost arrogant attitude, and it was normal to be startled.

At this time, it was evening, and there were many students who came to the credit exchange office to exchange at this time, and there were several people lined up at each window.

Judging from the normal speed, I am afraid that it will consume a few minutes when it is Li Changsheng's turn.

Without hesitation, Li Changsheng ran to one of the windows and said to the senior at the front of the queue: "This senior, I have something urgent, can you give me the seat?"

This is a second-year senior, and judging by his decoration and demeanor, this should be a civilian cadet.

The senior subconsciously wanted to refuse, but Li Changsheng took his hand and secretly stuffed a few things into his hand.

The senior was stunned for a moment, and soon realized that these were a few soul crystals according to the touch in his hand, he was a civilian student, and because there was no force behind him, he was still at the first-order level until now.

With the strength of this senior, he can only take on some of the simplest tasks, a few soul crystals seem to be very few, but it will take four or five days to earn them.

The senior clenched the soul crystal in his hand to prevent others from seeing it, and then let go of his seat, and said in a righteous tone: "Since the junior brother is in a hurry, then why not let it be given to you, junior brother, please!"

"Thank you, senior!"

Li Changsheng hurriedly thanked him, and didn't bother to look at the eyes of the people behind, and immediately handed the student order to the staff.

"All points are exchanged for earth and gold demon cores, and you can exchange as many as you can!"

In this week's accumulation, Li Changsheng has accumulated more than 700 credits.

When the staff saw the credits on the student order, they immediately shouted in a shocked tone: "All the seven hundred and forty credits can be exchanged for earth and gold demon cores?"

"That's right, hurry up, I'm really in a hurry now!" Li Changsheng was a little impatient and pulled his collar, he was really in a hurry now, and he didn't want to waste a second.

"Please wait a moment!"

The staff hurriedly started to operate, he could see that Li Changsheng was a first-year student, but there were a few first-year students with so many credits, this kind of person must be a person of the year in the school, and the future must be brilliant, but it is not an existence that he can fight evil.

In the process of anxiously waiting, time passed slowly, and soon nearly two minutes passed, and just when Li Changsheng was impatient, the staff finally handed a small bag to Li Changsheng.

"This is your demon core, and there are two boss-level earth demon ...... in it"

Before the staff could finish speaking, Li Changsheng had already jumped on Ash's back and disappeared in the blink of an eye.

"Hurry, hurry, rush!"

Under Li Changsheng's hurried voice, Ash exerted all his strength and returned to the No. 1 courtyard at the speed of a sprint.

It came and went quickly, and it took less than five minutes before and after.

Ignoring the surprised eyes of the people, Li Changsheng rushed into his bedroom, and when he saw that there was still a thin layer of energy left on the surface of the giant egg, he finally breathed a sigh of relief.

For the first time, Li Changsheng opened the small bag, and as soon as his spiritual power moved, dozens of demon cores flew up, and instantly touched the giant egg that had grown to a height of three meters.

The height of this giant egg is almost reaching the roof!

Among these dozens of demon cores, several are leader-level demon cores, and the rest are all elite-level demon cores, and the energy contained in them far exceeds the hundreds of demon cores before.

"At the current absorption rate, it can last at least twenty minutes, but I can't sit still!"

Li Changsheng first breathed a sigh of relief, and then felt that it was not enough to be safe, and after explaining that Kailan was optimistic about the Dome, Li Changsheng left the No. 1 courtyard again.

This time, instead of going to the credit exchange office or to the market district, he knocked on the doors of several neighbors.

Li Changsheng's neighbors are naturally Zhao Shuyi, Xu Xiangzhi and others who live in the courtyards of the other nine buildings!

Among these nine people, Li Changsheng is friendly with Zhang Yi, Luo Jie, Yuan Yongyan, and Li Runfeng, and it can be said that it is not a problem to borrow demon cores from them.

However, for the sake of insurance, Li Changsheng knocked on the doors of all the nine courtyards, after all, if they were not here, no one could say.

Fortunately, today is the first day back to the university, and most of the students did not go out, but nested in their rooms to rest.

Five minutes later, six people gathered in front of Li Changsheng, namely Zhao Shuyi, Xu Xiangzhi, Zhang Yi, Luo Jie, Yuan Yongyan and Li Runfeng, as for the other three, they didn't seem to be in the courtyard.

Roger looked at the others and asked suspiciously, "Brother Li, do you have anything to do with us?"

The others also looked at Li Changsheng with puzzled eyes, among which Zhao Shuyi and Xu Xiangzhi had a faint look of jealousy and vigilance in their eyes, for fear that Li Changsheng would calculate them.

"I summoned everyone here this time, mainly because I hope you will do me a small favor!"

Li Changsheng paused and continued: "As for me, I bought the Starry Sky Auction House in the Xuefu District not long ago. This time, I want to help you sell it, and in half a month, the Star Auction House will organize an auction, if you have goblins and treasures that you want to consign, you can hand them over to me, so as not to cause you trouble, I can also give you a five-percent discount commission!"

Since there was still plenty of time, Li Changsheng was not ready to borrow the demon core for the time being, if the giant egg had not absorbed enough energy within ten minutes, Kai Lan would fly over to remind him that it would not be too late to borrow it when the time came.

However, in order to delay time, Li Changsheng still promoted the Starry Sky Auction House, hoping to raise more lots, so that he could get commissions, second, to improve the reputation of the auction house, and third, to greatly conceal the origin of a large number of high-quality goblins in his hands.

These high-quality goblins are nothing more than my classmates, seniors, and mentors who have entrusted me to consign them for the sake of my face!

Even if it is his auction house, it is unpredictable, especially the auction house that has just been acquired, and there are a few people who will be loyal to him, so some cover-up is still necessary. Otherwise, if a large number of high-quality goblins are handed over to the auction house for consignment at once, and there is no good excuse, it will inevitably not be discovered by people with a heart for a long time.

This kind of behavior is no different from a child walking in the downtown with gold, the husband is not guilty, and he is guilty!

As a black-bellied demon master who has been practicing for 16 years, Li Changsheng is not zen to speculate on others with the greatest malice.

Regardless of whether they agreed or not, Li Changsheng handed his personal business card to the six people, and in addition to some of Li Changsheng's information, there was also a drawing of the head of an 'orange cat'.
