Spirit summons? I want to do it myself!

Lido did not spend too much time bargaining with the appraiser of the Blacksmith Association. Of course, this was also related to Lido's current image. The other party did not have the unscrupulous intention to make a fortune, and Lido was quite satisfied with the price offered.

Now Liduo has grown to the height of an adult woman. Although her face is childish, she is expressionless and exudes murderous intent. The Hanguang in her hand is obviously not an ordinary item. She simply puts the three words "not to be messed with" in front of everyone.

There was no way. Lido had killed a lot of monsters recently, so she was naturally surrounded by murderous aura. In addition, she had just experienced a fierce life-and-death battle, so her mental strength was still a little agitated.

But Lido had to endure the pain in her body and couldn't care about so many things, so her current aura was a bit scary. The stern face and expressionless face were the result of Lido's hard work to maintain.

Lido's requirements were not high, the bottom line was that she must not lose money! However, Lido actually underestimated the value of the Black Skull!

Black skeletons do not appear very often on the magical continent, because the birth of each black skeleton is a coincidence, and the right time and place are both essential!

The number of times humans kill black skeletons is even less, and there are almost no intact bones left after killing them!

Because killing black skeletons in the past relied on teamwork, most of the time success was achieved through the elves' ordinary attacks and magic skills. Therefore, the bones left after killing the black skeletons were either incomplete or burnt and their strength was greatly reduced.

The bones of the black skull brought by Liduo are complete and their strength is intact! Not only can they be used to make magic weapons, but they are also of higher research value!

A complete and well-preserved black skeleton! If you miss this chance, you may not get it next time! What's more, the black skeleton that Liduo killed is of a high level!

The appraiser of the Blacksmith Association had never appraised the bones of the Black Skeleton before, so he was unsure. It was not until Lido showed him the nearly spherical spiritual stone obtained from the Black Skeleton that he was able to determine the grade of the Black Skeleton.

This is not much different from a high-level monster! So the appraiser did not hesitate to offer a high price of 100,000 gold coins!

Lido thought the price was fair, so she settled the deal with the other party directly. Because the materials she was selling were rare materials, the appraiser also helped to exchange most of the gold coins for magic crystal coins so that Lido could take them away.

When Lido turned around and was about to leave, she suddenly remembered something, took out a stone from the lava cave from the bottom of the backpack, and placed it in front of the appraiser.

Originally, Lido was just trying it out, because she felt that this kind of stone was not much different from powerful magical materials.

But unexpectedly, when the appraiser saw the stone that Liduo took out, his eyes lit up!

It turned out that what Lido thought was correct. It was a kind of magical material, a raw stone of a magical material called obsidian. The inner wall of the training room of Lido Academy was made of specially treated obsidian!

The stone that Lido took out can be considered an above-average quality obsidian rough stone!

Obsidian can be said to be a strategic-level magical material, and it is never in sufficient supply.

It’s not that the reserves are low. You can find it in a small lava cave. Even if it’s one in a hundred, it shouldn’t be rare. But the key is that the mining volume is low! And obsidian is in the lava cave! How to mine it? !

Of course, the obsidian that Lido encountered in the lava cave is just one type, but the obsidian outside the lava cave is really rare and difficult to find.

The obsidian ore that has been discovered is mined with great care and used sparingly.

The piece of obsidian in Lido's hand is not only of good quality, but the appraiser can tell at a glance that it was mined from a lava cave!

If there is one, there will be two! If you can mine one piece of raw stone from the lava cave, there will be a second piece, a third piece...even thousands of pieces!

No matter how rare the complete black skull skeleton that Lido sold before was, it was only a one-time deal. How could it compare to the endless supply of raw obsidian?

Even if they bought at a high price and sold at a loss, the weight of the Qingyan City Blacksmith Association in the Beining Empire Blacksmith Association would be raised to the main city level! Then I would also be in a good position to get a promotion and a pay raise!

However, the price of raw obsidian is not high. After all, it needs to undergo special processing to become obsidian. But one piece of raw obsidian is worth 1000 gold coins!

The appraiser offered Lido a price of 1200 gold coins per square piece of the obsidian stone of this quality, and said that she would take as many as she could get!

Oh ho~ It seems that even if all the adult monsters in the lava cave are cleared out and the secret of the lava cave is discovered, the lava cave can still create value for Lido for a long time.

Lido sold several pieces of obsidian in the backpack for 100 gold coins. She did not sign a contract with the appraiser. She only said that she would sell them to him if she found more obsidian in the future.

In the future, Lido can go to the lava cave to mine one or two cubic meters of obsidian every few weeks. It's not as much as what Lido gets from catching monsters, but it's better in the long run.

Lido can still stay in the academy for about a year, and her total income will be nearly 100,000 gold coins.

By the time Lido graduates, she should be able to mine most of the small piece of obsidian ore, and the rest will be left for the right person. Of course, this is a story for later.

Liduo spent a lot of money to buy an intermediate purification potion to solve the problem of dark magic element infection in her body, and bought an intermediate recovery potion to recover most of her injuries. After returning to the academy, she ate a lot of marbled beef in the cafeteria, and then ate the remaining half of the white jade bamboo shoots after returning to the dormitory. She did not do any physical exercise, just waiting for the food she ate to be converted into energy and nutrition to repair the damage to her body.

If the body can recover to more than 90% after one night, it would be great. Li Duo still has some confidence in this.

With Lido's current physical condition, her body's recovery ability is also extremely strong. As long as there are no dark magic elements that prevent the body from repairing itself, and as long as there is sufficient energy and nutrient intake, the recovery speed is still very fast.

Lido was in a hurry to repair her body because she planned to enter the lava cave again tomorrow to check the situation behind the passage.

Even if there is danger behind the passage, if Lido goes to check it earlier, she can prevent it in advance or make up for the loss earlier, which will reduce the harm to the academy.

The next day, Liduo's physical condition had almost recovered as she had expected, leaving only the two big wounds that had not yet healed.

So Lido prepared to enter the lava cave again without any delay.
