The Witcher: Son of the Planes.

In order to verify the efficacy of the phantom potion, Colin actually came back "on an empty stomach" this time. After being promoted to level three, he had greater requirements for his "appetite". However, after the verification, he did not rush back, but stayed for a year before stepping into the phantom world again.

This time, Colin did not bring a second-level crystal core, but bought a large number of fire crystals from teacher Lina (not paid for yet), as well as mental potions from the market.

You read it right, it is the mental power potion. This potion played a significant role in Colin's early days. This time, Colin plans to sell this thing to the heavenly planes.

Since the effects of phantom potions and mental power potions are similar, and the value difference is so huge, why not do business in mental power potions?

For most of the natives in other planes, they may not have enough wealth to buy phantom potions. They may accumulate wealth for a long time but only buy a few bottles of phantom potions.

Although compared to the phantom potion, the mental potion has the disadvantage that its effect decreases each time it is taken, but there is basically no loss when taken for the first time. With this comparison, Colin doesn't believe that no one would want it.

After bringing the items, Colin chose the official store of Aries City because the value of your items can be assessed more quickly here.

"Welcome, sir. This is your second time here. What do you need this time? Or is there anything you want to sell?" The shop owner welcomed Colin warmly as always.

"Well, let's take a look at this first." Colin took out the fire crystal first. Based on the output of the plane controlled by the Lina family, most of the fire crystals were level one, and there were very few level two.

"Well, this mineral contains rich fire elements. I'll offer you 11 virtual coins for the first-level one and 115 virtual coins for the second-level one. What do you think?" said the shop owner.

Based on his last experience, Colin made a rough estimate and agreed to the shop owner's offer, but he did not choose to trade for the time being. Instead, he took out the primary, intermediate and advanced mental power potions and handed them to the shop owner.

The shop owner carefully observed the three medicines, then removed the corks from the bottles, smelled them, and then replaced the corks.

"I feel that this potion has similar effects to the Shadow Potion, but it still needs further testing. I cannot give you a price for now. I wonder if you are willing to accept our test. We will give you a price based on the test results. Of course, we will buy all three bottles. I wonder if you agree."

"How long will the test take?" Colin asked.

"About two hours." said the shop owner after thinking about it.

"Okay, I'll wait here," Colin said.

Time passed quickly and the shop owner came out with a hint of surprise.

"How did the test go?" Colin asked directly.

"The effect is very obvious, but I always feel that if it is taken for a long time, the effect will be discounted to a certain extent, because there is only one test product and it may not be very accurate?" said the shop owner conservatively.

"Well, I won't hide it from you. This is our local alchemical potion. Its effectiveness will decrease the more times it is taken, until it has no effect at all. But for those who take it the first few times, the effect is still good. The most important thing is that the value of this alchemical potion is not as high as the phantom potion." Having said this, Colin stopped and looked at the shop owner.

They are all smart people. As soon as Colin finished speaking, the shop owner understood the value of this thing. If Colin chose to run a shop himself to sell this thing, the sales volume of the phantom potion might be greatly affected.

Not only that, for many people, they could not afford to buy a few bottles of Phantom Potion in the first place, and with the appearance of this item, they would be even less likely to buy Phantom Potion. If Colin lowers the price of this item further, the Phantom Potion might rot in the warehouse.

For a moment, the shop owner began to sweat anxiously. Even a level two warrior could sweat anxiously. You can imagine how great the influence of this thing on the phantom potion is.

Although it was unclear how strong Colin was, he couldn't see through the other party's situation with his strength. He must be a third-level strong man. This made the shop owner give up any other ideas he had.

Now he only thought about reporting to the City Lord's Mansion as soon as possible and stabilizing the other party first.

In a short period of time, the shop owner thought a lot. Facing Colin's gaze, he felt a little guilty. Although he had no intention of harming the other party, at this moment, his desire to leave was revealed.

"What? Are you undecided? Then you can go ask your superior. I have no objection." Colin guessed the impact of the mental potion on the phantom potion, which must have put the shop owner in a difficult position.

"Thank you for your understanding. I'll be back soon. Wate, please entertain the guests." Before leaving, the shop owner asked his waiter to entertain Colin.

……

"Sir, this is the test data of the alchemical potion provided by a customer." The shop owner said respectfully.

After taking the data provided by the shop owner, the demigod-level expert Gategard Jamil took a look and said, "Being able to produce a phantom potion similar to that produced by the big guys in the spirit world shows that the plane behind this person is not simple.

If the other party uses this thing to impact the phantom potion market, it will indeed damage our profits.

How about this, I won't show up, you see if you can buy all of the other party's medicine, and then agree on a contract, the other party can supply this thing, but the quantity must be limited, and it can only be supplied to our store."

"What if the other party disagrees and insists on opening his own store?" the shop owner asked again.

"Disagree? Just tell him directly that this is the intention of the City Lord's Mansion if he still wants to stay in Aries City." Gategard did not believe that outsiders would dare to ignore the decision of the City Lord's Mansion, even if he was a third-level strong man, or a demigod strong man, because here, they had no right to make the decision, unless he was a god-level strong man.

"I understand. I will discuss it with the other party." The shop owner understood what the city lord said. If you don't pay attention when I talk to you about reason and transaction, then don't blame us in Aries City for being unreasonable.

When the shop owner hurried back to the shop, he saw Colin sitting there leisurely, with Wate accompanying him cautiously.

"Are you back?" Colin noticed the shop owner as soon as he came back.

"Well, let's go inside and discuss it in detail. I've already asked my superiors for permission."

"Okay." Colin was not afraid of any tricks they might play. Aries City had been able to stand for so long, it was impossible for them to harm their guests at will.
