Li Changsheng didn't think much about it, picked up the wood chips on the side and looked at it.

"It turned out to be Ying Long's dragon scales!"

Li Changsheng sighed, among the dragon clans, the strongest nature is naturally the only nature of the ancestral dragon and the candle dragon, and the next ones are basically the green dragon and the Ying dragon, and they are also in the ranks of the top divine beasts.

It is precisely for this reason that this Ying Long dragon scale is undoubtedly a very precious forging material.

Of course, it is not comparable to the Xuanwu turtle shell on the first authority exchange list, after all, even if it is a broken Xuanwu turtle shell, the volume is far greater than that of Ying Long's dragon scales.

Li Changsheng picked up the dragon scales of Yinglong, and his hand sank slightly, the weight of this dragon scale was hundreds of catties.

After putting away the dragon scales, Li Changsheng hesitated slightly, and then used the last voucher to open the treasure box placed in the corner of the desk.

This time, it's a delicate dark green pendant.

Li Changsheng picked up the wood chip, only to find that this was not a treasure, but a very precious one-time treasure.

This pendant, called the Flower of Butterfly Love, is also a treasure left by the original headmaster, and after activating it with spiritual power, it can turn into a spatial portal, which is thousands of miles away.

To put it simply, this is a life-saving treasure, even if Li Changsheng is hunted down by the king, he can quickly activate the flower of butterfly love to get out of danger.

If Li Changsheng is used in Langya Kingdom, it is very likely to appear in other countries.

The only flaw is that the space portal is not based on human will, it is completely random, and it may appear in dangerous areas, such as appearing in the family of a certain king, or appearing in the territory of a goblin above the demon king level, etc.

Even so, the value of the Flower of Butterfly Love is still difficult to measure by value, for Li Changsheng, it is comparable to a treasure, which can provide further protection for his safety.

"Sure enough, the first headmaster is the most generous!"

Li Changsheng praised, he deserved to be the king, and he was much more generous than other principals.

After completing the selection, Li Changsheng left the Treasure Pavilion without any nostalgia and returned to the No. 1 courtyard.

In the backyard, Li Changsheng took out the fruit shell and began to scan it with mental power.

Under this sweep, Li Changsheng smiled.

Although the energy fluctuations of this husk were far inferior to the seeds of the Tree of Life, it was still at the Heaven and Earth Essence level.

If there is no accident, this is a high-level spiritual root seed, and it is also a high-level spiritual root related to the power of the stars.

However, before the husk took root and sprouted, Li Changsheng didn't know which kind of star-like high-grade spiritual root this was.

The energy fluctuations contained in high-grade spirit plants are juxtaposed with the treasures of heaven and earth, but the former can still be called a living thing, while the latter is a completely dead thing, and there is an essential difference.

Even after so many years, the husk still contains amazing vitality due to the well-preserved relationship.

Without hesitation, Li Changsheng transplanted a spirit plant near the Tree of Life, and only then did he bury the husk in the soil and water it with some water of life.

I believe that with the care of the little obedient, and the breath of the tree of life, the water of life and the soil, such an excellent growth environment, the entire Langya country is also unique, I believe that it will not be long before this shell will take root and sprout, and then it will be able to uncover its true face of Lushan.

This time, Li Changsheng rarely did not purify his blood, and he planned to wait for the imitation demon refining pot to be refined, and then test the efficacy of the imitation demon refining pot, which could also effectively avoid waste.

Li Changsheng put down the golden nut and screw, and not long after, Ning Bizhen came to him.

"Bi Zhen, how is the investigation?"

Li Changsheng naturally asked about credits.

"Dean Zhang Kaishuo has the most credits, he has accumulated more than 500,000 credits, followed by Dean Ning Wei, who has only more than 300,000. ”

Li Changsheng was not too surprised, Dean Zhang Kaishuo was simply an otaku, he often retreated for alchemy, and almost all the high-grade pills in the academy came from him, which also accumulated a lot of credits for him.

Like Zhang Kaishuo, Ning Wei is also a veteran dean, and she has also accumulated a lot of credits.

Li Changsheng asked suspiciously, "What about Principal Xu?"

"A few years ago, Principal Xu first exchanged the "Liangyi Weichen Demon Decision", and ten months ago, he exchanged a barrier-breaking pill and a batch of precious materials, and the remaining credits were less than 100,000. ”

Ning Bizhen investigated very carefully, and explained everything in detail.

"How many credits can the university give you in a year?"

After becoming the first school, the salaries of the top leaders and tutors of the Yuanling Academy will definitely rise, which is a certain thing.

"30,000 credits a year, you're short of credits right now?"

30,000 credits seems like a lot, but Ning Bizhen is a pseudo-king, and the daily consumption is also very large, and there will be 10,000 credits left in a year.

"I want to exchange it for the Golden Lantern of the Mixed Dollar!"

Li Changsheng did not hide it, and revealed his plan and inventory.

Ning Bizhen was full of surprise, she knew the exchange price of the mixed yuan golden lantern, even if she exchanged the credits for a halving discount, she still needed 1.5 million credits.

If you use purchasing power to calculate, one and a half million credits is almost equivalent to more than three million soul crystals.

With such a large number, there are several forces that can take it out, and even if they take it out, it will be painful.

Except, of course, for the wealthy royal family!

"Why don't I help you raise it?"

"Then you're welcome!"

Li Changsheng did not refuse, Ning Bizhen is more suitable than him to come forward to raise credits, after all, Ning Bizhen's identity is there, and I believe that there will be many high-level and mentors who are willing to give Ning Bizhen face.

Li Changsheng prepared for a while, gathered a large number of resources, demon cores, and soul crystals that were useless to him into a spatial ring, and handed it to Ning Bizhen.

"You can use these resources to exchange them for credits. By the way, give me a copy of Dean Zhang Kaishuo's demon pet information. ”

"Wait, I'll write to you now. ”

Ning Bizhen was very aware of the situation of the other six high-level leaders, and with her ability to never forget, she had already memorized all kinds of information about them in her mind.

Soon, Li Changsheng got a more detailed information.

Zhang Kaishuo has a total of eight contract demon pets, only one is the best demon pet, and the remaining seven are all top-grade, either the commander or the monarch race.

Li Changsheng was not surprised, Zhang Kaishuo was an old sixth-order powerhouse after all, and after so many years, he could always get some heavenly treasures that could be used for the evolution of demon pets, such as Yaochi Golden Jade, Shui Mu Miao True Pearl, and Bloodline Fruit.

Zhang Kaishuo's only top-grade demon pet is named Jin Yu alpaca, with a pure-level Bai Ze bloodline, lord-level 9th-order realm, this top-grade demon pet has broken through a total of three times, but unfortunately it all ended in failure, and the success rate of breaking through the demon king level is less than 5%.

Because of this, Dean Zhang Kaishuo could only temporarily give up allowing it to continue to break through, and instead began to seek items that increased the success rate of the breakthrough.

It's a pity that this kind of natural treasure is too rare, there is almost no flow in the market, coupled with the situation that there are many monks and few porridges, and the situation of being shy in the pocket, over the years, Dean Zhang Kaishuo has not been able to get an item that increases the probability of a breakthrough at the demon king level.

Similar to Dean Zhang Kaishuo, Dean Ning Wei is in the same situation.

"I just have a jar of Bai Ze's essence blood, and I don't know how many credits I can get in exchange?"

Li Changsheng didn't go to the information of other demon pets, and silently calculated the gains and losses in his heart.

This jar of Bai Ze's essence blood is of little use to him, and can only be placed in the space ring to accumulate dust, rather than this, it is better to use it to trade with Dean Zhang Kaishuo, and both sides take what they need.

According to Li Changsheng's conversion, if Jin Yu alpaca evolves to the next stage, the possibility of breaking through to the demon king level is probably just over two percent.

Although the probability is not very high, it is impossible for Dean Zhang Kaishuo to let go of this opportunity, after all, he is almost seventy years old, even if he does not have the luxury of becoming a king, but the pseudo-king is his life goal.

As for how many credits this jar of Bai Ze essence blood could be exchanged for, Li Changsheng thought of the Bi Fang essence blood that was auctioned half a year ago.

At that time, Xu Wenhua auctioned off a bowl of Bi Fang's essence blood at the price of 80,000 soul crystals.

Bai Ze's essence blood and Bi Fang's essence blood belong to the same grade of essence blood, and the value is almost the same, and one jar is equivalent to four bowls of capacity, and this can of Bai Ze's essence blood can probably be sold for 320,000 soul crystals.

Of course, the price can't be calculated like this, after all, this is a large jar of Bai Ze's essence blood, if it is really put up for auction in the auction house, the average price must exceed that bowl of Bi Fang's essence blood by a lot.

Li Changsheng estimates that this jar of Bai Ze's essence blood can probably fetch about 500,000, but if it is converted into 250,000 credits in terms of the purchasing power of credits, it is still a long way from exchanging it for a mixed yuan golden lamp.

Thinking of this, Li Changsheng suddenly felt a headache, he glanced at the Biren beside him, with Ning Bizhen's full assistance, he believed that he would be able to raise a lot of credits in a short period of time, and he had a little more expectations in his heart.

After making a decision in his heart, Li Changsheng seemed to think of something, and took out Shui Mu Miao True Pearl and Yao Chi Golden Jade.

"By the way, Bi Zhen, these two treasures are of little use to me, I thought I'd better leave them to you, just to be useful for the six-armed Naga. ”

This time, Ning Bizhen did not shirk and accepted it generously.

In a sense, the six-armed Naga is a 'token of love' given to her by Li Changsheng, which has extraordinary significance to the two of them.

It's just that the goblins with the blood of the twelve-armed Naga are too rare, and they live in the depths of the ocean, so Li Changsheng can only settle for the next best thing, and temporarily use the heavenly and earthly treasures to promote the six-armed Naga to complete the evolution.

"When Cortana reaches the 9th rank of the lord, I will give it to her again, and maybe she will be able to become a demon king in one fell swoop. ”

Xiao Na is the nickname that Ning Bizhen gave to the six-armed Naga, and it will probably take a few months for her to reach the 9th rank of the lord.

"I called you over this time, in addition to these materials, the main thing is to refine the imitation demon refining pot, in order to avoid accidents, I need your help. ”

Li Changsheng waited for this moment for more than half a year, imitating the combination of the Demon Refining Pot + the Book of Bloodlines, which made people feel excited just thinking about it, and they didn't know what level they could increase the extraction rate to.
