The Witcher: Son of the Planes.

Colin didn't even have 2 wizard coins on him.

Colin looked at the wizard on the field anxiously. It was not something he could snatch away. He turned around and looked at Nick. Nick didn't seem to be very interested in this.

So, Colin began to ask Nick privately: "Wizard Nick, lend me tens of thousands of wizard coins, and I will pay you back with a 20% increase in the price."

"Hmm? Are you interested in this thing? It doesn't match my personality."

"Don't worry about it. Just tell me whether you want to lend it to me or not."

"...Okay, just name the price and I'll pay." Nick thought about it and agreed to Colin's loan request. Giving timely assistance is always better than adding icing on the cake.

With Nick's support, Colin suddenly became rich and powerful.

"3."

"Hey, something's wrong with you, Wizard Colin. You're not an ice wizard, so why do you have to fight for this thing? Well, let me think about it. Is it your lover who wants to use it?"

"3."

"Who do you care who I give it to? 4." Colin had no choice but to follow suit and bid.

……

"How about this, if you are willing to buy my dark flower, I won't fight with you about this, how about that?"

"Well, how much is your offer?" Colin thought for a while and then spoke.

"This is a good experimental material and very rare. How about the starting price of 5000?" Jacob said with a smile.

Colin looked at everyone present, and none of them were interested in buying it. If they were interested, he would have made an offer the first time he took it out. With Colin's limited knowledge, he felt that this dark flower would be worth no more than 1000 wizard coins, but in order to get the ice element core, he still suffered this loss.

In the end, Colin bought the Ice Elemental Core for 4 wizard coins and the Dark Flower for 5 wizard coins.

Well, the Dark Flower can still be used by Rose, so it can’t be said that it was bought in vain, it’s just that the price is a bit higher.

The exchange meeting did not last long, less than 2 hours in total. After the exchange, we chatted for a while and then it ended.

Afterwards, Colin and Nick left Jacob's manor together. This time, Colin borrowed a total of 2 wizard coins from Nick, and agreed to return 5 wizard coins within two years.

Colin is not worried about the outstanding debt. He can ask Helen for some money when the time comes. With the offerings from the Heaton family and Willisel's output, repayment will not be a problem.

The biggest gain today is finding the ice element core.

I returned to Heaton Manor happily and immediately found Edith on the fourth floor of the Wizard Tower.

"Guess what I bought today?" Colin said happily.

Seeing Colin's happy expression, Edith felt the same way, "Bought dragon's blood?" She thought Colin had found the experimental materials he urgently needed.

"No, guess again."

"Or some kind of body-refining potion?" Edith guessed again.

"No." Colin shook his head again.

"Stop guessing, just tell me now."

"Look, what this is." After saying that, Colin took out a box and handed it to Edith.

After Edith took it and opened the box, she immediately felt the temperature around her drop by several degrees. "Ah, is it really the ice element core?"

Edith looked at the item in her hand and then at Colin. She couldn't believe that Colin bought this for her. She didn't know if it was because of luck or wealth. Logically speaking, this thing was hard to come by and it couldn't be bought with a family fortune of 2.

Colin did not create any mystery in front of his lover and quickly told her about the loan. He was lucky. Knowing that he had better luck than ordinary people, Colin attributed his ability to buy the ice element core to luck.

"Edith, now you can try to advance, but you need to refine this in advance, and it's not easy to swallow it directly."

"Well, can you refine it?"

"I'll ask Teacher Lina. This shouldn't be too difficult. Just liquefy it for easier absorption without adding any other materials. I think I should be able to do it."

"Okay, but it's better to be cautious and do some experiments in advance. Don't you have some apprentice-level fire element cores? Practice first."

"Don't worry. I will be extremely careful when it comes to your affairs. Just wait for your promotion and adjust yourself in the next few days."

"Well, but you can take a break tonight." Looking at Colin with seductive eyes, Edith took the initiative to hold Colin.

"Hey, hey, I still have experiments to do." Colin was thinking whether he should drink the bottle of intermediate physical potion he just bought?

"Let's go. I'm happy today." Edith started without saying anything.

Omit 5000 words here.

……

The next day, Edith got up early and went to the quiet room alone to adjust her state.

It took Colin a long time to wake up. Edith was so brave yesterday. Could it be that she had been holding back before?

Why do I feel a little sore in my waist? Oh, I am in my 50s after all, and my physical condition is bad. I didn’t even have time to drink that bottle of medicine yesterday.

Now that I'm up, I'm not in a hurry to drink that. I'd better contact the teacher first. It's been a long time since I came here, but I haven't contacted the teacher on my own initiative.

"Teacher Lina." With the help of the energy pool of the wizard tower, Colin contacted Lina without spending much mana.

"Colin, is there anything wrong? I heard from the family that you have performed very well in Willisel, and the family is quite satisfied with you."

"Thank you for your praise, it was just luck. This time I came to you mainly to ask about the technique of refining the Fiery Elemental Core. I have an Ice Elemental Core that I want to refine into a potion."

"Oh, this is easy. It's similar to the method I taught you before to make the spiritual potion. Just do this first, and then..."

"Okay, thank you, teacher. Goodbye, teacher." Colin was afraid that Lina would give him other tasks, so after getting what he wanted, he quickly hung up the phone.

"This kid is just refining an ordinary potion, it's just that the materials are hard to find." Lina didn't care about anything and quickly started her own experiment.

After obtaining the refining method, Colin quickly tried to refine it using his apprentice-level fire element core.

It cannot be said that the refining method is easy, it can only be said that the refining method is too easy. Colin did not even have to work hard and succeeded in one go. To put it simply, it is to use powerful mental power to compress the heart core, put in a certain amount of energy potion, and finally mix them into a bottle of solvent.

However, it is easier said than done. The production method is simple, but the compression requires strong mental strength, which is beyond the ability of ordinary quasi-level wizard apprentices. This also leads to many quasi-level apprentices being unable to make it even if they have the raw materials.

After Colin experimented twice with his apprentice-level fire element core, he rested and adjusted for a while before starting to compress it with the ice element core. Relying on his mental strength of more than 30 points, Colin finally succeeded in refining the ice element core potion.
