The Witcher: Son of the Planes.

The library in Tibande City is about the same size as the one in Tarkingham. Many of the books in the collection are repeated, but there are also some differences. In addition to books on humanities and geography, there are also special features on Istar, the most powerful magic organization in the Victorian World.

Colin was willing to spend this time reading the books in the national libraries of the three duchies, not only because the cost was minimal and they were easy to read, but more because there were not many channels for him to exchange knowledge at this stage, and what he gained from his own memory and the storage from the Earth scan would eventually help him.

Although the library in Tiband City also had a rich collection of books, the study time was not as much as that in Tacklingham. It only took three months to finish reading all the books I wanted to read.

Afterwards, Colin sent a message to Jesse and set off for Gotford City again.

Colin has been to Gotford many times. Although Colin belongs to the Principality of Huiyao, he comes to Gotford the most. This is because Oscar switched to become a wizard as soon as possible, and also because of the freedom and openness here.

Because Oscar had not returned yet, Colin was too lazy to contact his "acquaintance" here, so he went straight to the library. After showing his library card, Colin once again dived into the ocean of knowledge.

This time it took even less time. Colin finished his reading journey in less than two months.

After coming out, Colin, who had nothing to do temporarily, went to the law enforcement team's base. After a brief exchange with Bill and Ferren, he prepared to return to Emerald Island.

Coincidentally, Chief Sophia of the underwater world had been contacting Colin for more than half a month, but because Colin was busy with "reading and studying", he never left the library, and the witchcraft ball had been kept in the alien space and had not been taken out, resulting in the information being received only when he arrived at the law enforcement team's base.

After Sophia contacted Colin, she didn't say much else. She just hoped that Colin would come to their tribe's place to discuss things if he was free.

Colin was also impressed by his luck in getting into trouble. How long had it been quiet before something happened again?

But Colin did not refuse. If there is something going on, it means there is a demand for interests. People with wealthy families may not be interested. But it is different for Colin. His family is just starting out and everything needs money. Any money he can earn is good. Since Sophia has a need, he might as well go for it.

It was not until Colin arrived at the headquarters of the Arni Mermaid Tribe that he understood why Sophia wanted to see him.

"Wizard Colin, I invited you here this time because I want to do business with you. How many giant squids do you have left? I want to buy them all." Sophia could be polite and directly stated her purpose.

"Oh? Why do you suddenly want to buy that creature? Aren't the 10 I gave you last time enough?" Colin was also a little confused.

Sophia paused, wondering whether she should tell Colin the truth. If she told him, Colin might not sell it to her. If she didn't tell him, he might be suspicious and might not sell it to her. But she really needed it, so Sophia finally chose to make it public.

"I won't hide it from you. Among the ten giant squids you gave me last time, one actually broke through to level one."

"What? Breakthrough to level one?" It has been some time since Colin came back from the Blue Nabo plane. He has been wondering when he could harvest a batch of level one slave creatures. However, he has been in the alien space for a long time, and no giant squid has broken through so far. He didn't expect that a squid with a breakthrough would appear not long after being given to the mermaid tribe?

“Well, we didn’t notice it at first. Although there was a slavery contract governing them, which only required them not to hurt anyone at will and not to leave the waters of the Victoria Islands, because there had been no war, they were basically in a semi-free-range state, and we didn’t pay much attention to them.

But one time, when the elders of the tribe went to their activity location to carry out a mission, they suddenly found that the breath of one of the squids was not right. After asking, they found out that the guy had actually been promoted a few days ago.

So, you know, I want to buy it and consider it for future battles."

Colin listened to Sophia's words and gradually realized that he had been thinking wrongly. After all, squids are marine creatures. How could they be promoted if they were placed in another dimension?

The environment is not right. They should have been put down in the sea earlier. Maybe more people would have been promoted. It's a big loss. Not to mention anything else, even if those 10 giant squids were promoted, they would never be promoted with just the witchcraft of summoning water elements. The most important thing is that this batch of giant squids contain the blood of Siband, the original guardian of the Lannabo plane. That is the blood of a demigod-level creature, and the upper limit is still good.

"I can't sell them all to you. You don't know the bloodline of this creature. The upper limit is demigod. As far as the forces on the continent are concerned, how many demigods can there be? It's not that this batch of squids can reach that upper limit, but there is always a hope that it won't. Besides, I estimate that based on the value, you may not be able to afford it..."

"Oh my god, this guy still talks so irritatingly. It seems that I thought too simply. I knew that once I told the truth, he would ask for a sky-high price." Sophia was also a little impatient, but there was nothing she could do. Colin was like this. He would never let go if he couldn't get the upper hand.

"You should first tell me how many you have, and then we can discuss the price."

"There are several hundred of them, most of them are at the quasi-level, and a few are at the advanced level."

"How much are the quasi-level ones? How much are the advanced ones? You should just tell me a number so that I can see the strength of my clan and see how many I can afford. After all, you said that we can't afford to buy them all."

"Uh... let me think about it." Although Colin likes money, what he said just now was just casually. According to the ideal situation of all advancing, he did suffer a loss last time, so the other party couldn't afford it. As a result, Sophia directly fought back with words.

Women, oh no, mermaids, hey, really don't want to suffer any loss at all.

"Five quasi-level giant squids for one level one energy core, and ten advanced level giant squids for one level one energy core." Colin said after thinking for a while.

"What? This is too expensive. It's ok for a quasi-level item, but you dare to ask for so much for a high-level item? This is too shameless."

"I think what the giant squid lacks is an opportunity. Don't you already have a ready-made example? Maybe after a while there will be a few more first-level slave creatures. How many first-level professionals do you have in your tribe?

As for the advanced giant squid, don't take it lightly. It's not that difficult to reach the quasi-level. The key is to block the chance of a breakthrough. Think about it carefully."

Although Sophia thought what Colin said made sense, she didn't want to change it just like that. She argued with Colin for a long time before deciding on a price.

The final exchange ratio is eight quasi-level giant squids for the energy core of a first-level creature, and fifteen high-level ones for the energy core of a first-level creature. As for the chance of breakthrough, you can only gamble.

After deciding the price, it will be easy to discuss how many to buy. Sophia really took out all the family property. If she can't use them herself, she can sell them to other wizard forces in the underwater world. There will definitely be profit, no loss.

In the end, Colin obtained the energy cores of 14 first-level creatures and sold them to the Arni Mermaid Tribe for eighty quasi-level giant squids and sixty high-level giant squids.

Having completed the transaction, Colin did not stay long before surfacing and heading towards the Emerald Island.
