The Witcher: Son of the Planes.

"Sir, may I know the name of this alchemical potion?" said the shop owner.

"We call it mental potion over there," Colin replied.

"That's quite fitting. It does have an extraordinary effect in improving mental strength. I wonder how the customer wants to deal with this mental strength potion?"

"Well, now comes the real show. You've hit the nail on the head." If Colin could bring a group of people with him, it would definitely be more appropriate for him to run the store himself. However, in the current situation, it is obvious that he is just a passer-by, and it is far better to find a force to cooperate with.

In Aries City, the most powerful force is the City Lord's Mansion.

"I would like your store to sell it on my behalf," said Colin.

"Oh? What's the exact selling price? How much can you give us?" the shop owner asked.

"You are aware of the value of the spiritual potion. I cannot guarantee the interval between my visits to the virtual world. I can only say that I can bring a batch of it with me once I come. As for the price, I think you should have a more accurate valuation, so I won't quote you a random price.

I only have two points to mention. First, provide me with a Spirit Shadow Bag with the largest capacity, so that I can collect some items from various planes. Second, after selling the spiritual power potions I brought, 80% of the payment can be settled with Phantom Potions and 20% with Phantom Coins. "

Although Colin did not mention a specific price, the shop owner was already very satisfied. He didn't even need to say anything "threatening" to the other party, and the other party was so tactful in cooperating. It seemed that the other party was also a smart person.

Not only that, the other party mentioned that 80% of the settlement would be made with phantom potions. Isn't this just giving money to yourself?

You are very tactful. I guess we will have to interact more often in the future. As for the Spirit Shadow Bag with the largest capacity?

This thing looks complicated, but to be frank, it's not much different from space equipment. It's not expensive in itself, it's just that other people don't know how to make it, so why not give him one.

"On behalf of the City Lord's Mansion, I have agreed to the guest's request. If the guest has no other requests, please exchange all the spiritual power potions you brought this time."

Colin put 101 bags of mental power potions into the 70 smallest spirit shadow bags, each bag containing 100 bottles, including 200 bottles of advanced mental power potions, 1800 bottles of intermediate ones, and 5000 bottles of primary ones.

Fire crystals, only 50 pieces of the second level, 260 pieces of the first level. (10 pieces per bag.)

To facilitate calculations, the shop owner proposed a future trading method: other items would be settled with phantom coins, and all mental power potions would be exchanged and settled with phantom potions.

After thinking about it, Colin agreed and stopped worrying about the 80% and 20%.

The final agreed exchange ratio of Shadow Potion and Mental Power Potion is:

The exchange ratio of advanced mental power potion to advanced phantom potion is three to one, the exchange ratio of intermediate mental power potion to intermediate phantom potion is four to one, and the exchange ratio of primary mental power potion to primary phantom potion is five to one.

After collecting all the mental potions and fire crystals that Colin poured out, the shop owner quickly gave the total value, and put the exchanged phantom potions and phantom coins into a "largest" spirit shadow bag and handed it to Colin.

(My brain capacity is a little insufficient, so I won’t calculate it in detail)

"I wonder if there are maps of other cities here?" Colin asked after the transaction was completed.

"Huh? Do you have any thoughts on going to other cities?" the shop owner asked cautiously. He had just made a deal and he didn't want to just make it a one-time deal. If Colin sold the mental power potion to other cities, it would have a big impact on Aries City.

"Don't worry, since we have made an agreement with Aries City, we will not sell it to other cities. It's your business if you want to sell it. I just want to understand the situation in this plane. We wizards are the professionals who pay the most attention to contracts and equal exchanges." Colin seemed to have guessed the other party's concerns and said bluntly.

"I'm sorry for not asking for your name."

"Well, you can call me Wizard Snape." Although Colin didn't know what means the other party had against his real name, he still kept it a secret and mentioned Snape, with whom he had been in close contact recently.

"Okay, Wizard Snape, other cities are actually similar to our Aries City. They have everything they need. Why would you go so far away?"

"...Okay, let's not talk about this for now. There should be a map of the area near Aries City, right? I need a direction to hunt some phantom creatures, right?"

"...I have this. In consideration of our future transactions, I'll give it to Wizard Snape. But I hope you won't pass this map on to anyone else." The shop owner handed Colin a map of the nearby area and said.

After Colin took it, he took a quick look and saw the village he had passed by before, but strangely, there was no mark of the Phantom Sea or the place where he first landed.

However, with a map for reference, I believe it is easy to find out about other neighboring cities, so Colin will not force it.

Before leaving the store, Colin wanted to rent a place for a long time, but he thought of the other party's concerns and finally gave up.

Looking at Snape (Colin) walking away, the shop owner always felt that the other party was not only here to obtain some resources, but had other intentions.

Never mind, I hope I guessed wrong.

……

Colin left the official store. He still had a lot of time left, but with so much gain, he didn't seem to need to rush out to hunt any phantom creatures. Instead, he wanted to know more about the entire phantom world. It would be even better if he had the opportunity to learn about the situations in other planes.

But such opportunities are rare and need not be sought. Even though everyone is staying in Aries City, they talk more about the value of things and trivial matters related to transactions, and never talk about the situation in their respective planes.

Of course, this does not apply to cases where others take the initiative to inform you after they have become good friends.

But who can know whether others will use some means to follow the scent and track down to your own dimension?

Therefore, being cautious is the norm, and protecting your own plane situation (coordinates) is of utmost importance.

Colin had thought about making a sneak attack on someone and finding out some information through soul magic.

But the people here are very vigilant, and even with Colin's level three strength, it is difficult to find a corresponding opportunity.

Colin, who was troubled by this matter, accidentally saw a man in Aries City one day.

A person I met a long time ago, a person who took the initiative to reveal his own dimension in order to scare others away.

I didn't expect that he also came here and has been successfully promoted to the second level.

It seems that I have another channel to learn the truth about the phantom plane.
