The Witcher: Son of the Planes.

It took nearly half a year to purchase the supplies that Snape needed, mainly because some scarce items took a little longer, so Colin had to fill up several space equipments before he could install them all.

This time Colin went to the underground world for the transaction alone. He didn't say a word along the way and didn't delay anything. He rode Charles to New Trey. After arriving at New Trey, he didn't see Snape, but he had Beta as a guarantor. After Beta paid Colin the agreed price, Colin was ready to leave.

Colin didn't insist on meeting Snape this time. Beta had already settled the bill with him, so there was no need to worry too much.

This kind of transaction doesn't happen often, and no one knows when the next one will happen. After telling Beta that they'll contact each other when there's a chance, Colin set out on the journey back to the surface.

As a result, before Colin left the first floor of the underground world, he received a message from Snape, hoping to meet at the Evening Breeze Tavern. Colin thought there was a problem with the quantity of supplies, so he turned around and went back without thinking much about it.

In the Evening Breeze Tavern, based on the information collected from Earth last time, although Snape was well disguised, Colin still recognized him sitting in the corner at the first time.

"Why are you in such a hurry? Is there something wrong? Is the quantity of supplies not correct? I'm about to return to the surface." Colin asked while sitting opposite Snape.

"I have received news from Beta that the supplies have been delivered. There is no problem with the supplies. I am not telling you this. I want to ask, do you want to make some other money?" Snape asked.

"What? Just say it."

"Some areas under our control are short of personnel, and some forces lack manpower to conduct experiments. I hope you can help purchase some. The cost is no problem. Don't worry, I will definitely satisfy you."

"Staff? Do you mean the native personnel of the wizarding world, or the personnel from other dimensions?" Although Colin was somewhat puzzled by Snape's statement, he still asked directly.

"We also have channels to buy people from other planes. We just hope to buy some people from this plane, or even slaves..."

"I've heard that dark wizards will stop at nothing to improve their strength. Is it because Dalavini doesn't have enough people? They want to harm the people in this plane?" Colin was also a little unhappy. They didn't take human life seriously.

"I'm afraid I can't help you with this. It's really not convenient for me to do this business. I'm sorry." In the end, Colin suppressed his anger and said.

Snape looked at Colin deeply. He thought that although Colin was a white wizard, he still had a strong desire for money. He thought that this transaction request would go smoothly. He didn't expect this guy to be so naive. He couldn't bear to give up some ordinary humans? It seems that he has to spend a lot of money.

"I have a book that helps you cultivate your spiritual power. It can be used in conjunction with your meditation practice. I can't say how much more it will do, but it should definitely increase the effect by 50%. This is also the secret technique I'm practicing now. Are you interested?"

"Oh? I'm indeed interested. What do you need?" Colin became interested as soon as he heard this. He was worried about the slow improvement of his mental strength.

Snape just continued to look at Colin and said nothing.

Seeing that Snape didn't say anything but looked at him, Colin understood that he wanted him to agree to buy a batch of humans first before he was willing to discuss the specific transaction.

Colin pondered and did not speak. Although he was not from this world, he had lived in this world for more than a hundred years and had long regarded himself as a person of this plane.

Although he was not a good man, he was not an evil person either. He had used sub-humans from other dimensions for experiments in the past, which was enough to cross his bottom line. This time it was obvious that Snape was planning to buy a batch of local humans and sell them to other forces to use as experimental specimens.

If he didn't do this business, Colin believed that he could be promoted to the second level through his hard work, but if he did this business, he might be promoted many years earlier. He was not a child of a big family and there were still many things he needed to accomplish. If he could be promoted earlier, the results of many things might be different.

But, can he really break through his long-standing persistence? Last time, Edith and I made an exception in Willisel and killed a passing wizard. This time, in order to be promoted, can he break through again?

Although practicing witchcraft does not require training the mind like in the immortal cultivation novels of the previous life, if one abandons long-standing persistence and fails again and again, won’t it affect one’s future path?

Colin found it difficult to make a decision for a moment, and he was still struggling in his mind.

Snape on the opposite side was not in a hurry either. He looked at Colin quietly, waiting for Colin's reply.

He knew that the tempting thing he threw out would definitely change Colin's mind. These white wizards were so sanctimonious. They obviously wanted it very much, but they still had to find all kinds of reasons. They were very hypocritical and not straightforward at all.

Unlike us dark wizards, we are very direct and never look for any excuses. If we want something, we will buy it, rob it, or hide from it. We are willing to offend or kill as many people as possible as long as it is for ourselves.

Colin finally made up his mind to do it. When he looked up at Snape, he found that Snape was looking at him straight with a smile on his lips, as if he had guessed that he would agree.

"Damn it, did you think you had me? If not for..., nevermind, just assume that you won this time." Colin thought helplessly.

"I agree. You can take out your book now."

Snape took out a rubbing book from his space ring and handed it to Colin. Colin only glanced at a few pages and felt that what Snape said was true and should be effective for him. If what Snape said was true, then his promotion to level two would be advanced by many years.

"What do you need?" Colin asked after returning the rubbing to Snape.

"Anything is fine, as long as it complies with the principle of equal value. As for the personnel I mentioned to you at the beginning, I will also pay them, but that is another matter."

Colin silently thought about the various items he owned. It was impossible for him to give him the method of refining the manganese heart potion, and Colin did not want to trade the refined potion to him.

As for the other things, Colin had thought of their uses in advance. No, simply paying with wizard coins would probably not be acceptable to this guy. Forget it, just give him some Fountain of Life. This was all he had, the most of.

After thinking for a while, Colin took out seven drops of the Fountain of Life and handed them to Snape.

As soon as the Fountain of Life was taken out, Snape felt a powerful life energy. In these years in Dalavini, he had used many secret techniques to improve his strength, and many of these secret techniques were based on harming his own lifespan.

Snape recognized the thing Colin took out. It was the Fountain of Life. Although he had no chance to take it, some big forces still had this thing in their hands, but he had no channels to obtain it.

"That's not enough. My book can be traded repeatedly, but yours will disappear once you take it..."

"I... can this be calculated like this? Never mind, I'll give you 3 drops at most, no more. Besides, the effect will decrease after each dose, so it's useless if you ask for more." Colin didn't like Snape's greed, but he really needed the book.

"Okay, deal! I hope you can send those people here as soon as possible, or send them to Xintele. I need them urgently."

"I will keep my promise. Well, goodbye for now." The last time Colin talked with Snape, he thought he might be able to become friends with him. After what happened today, Colin felt that he could not get along with him. He did not like this kind of person at all. He was too calculating. It would be better to maintain a trading relationship and not get any closer.
