The Witcher: Son of the Planes.

Although the exchange between Colin and Raul seemed to be carried out under Colin's semi-forced action, it was a mutually beneficial thing, so Raul didn't feel that he had lost much.

The rest of the conversation, in which Colin asked about routes to other cities, seemed less important.

In Raul's mind, a city's route map was not a secret at all, and he didn't care whether it betrayed much information about the magical world.

So, Colin easily made a copy of the route map from Aries City to Taurus City.

After Colin told Raoul his name (Snape), they ended their conversation.

Although there is still a lot of time left, Colin does not want to go to Taurus City this time. He hopes to proceed with the transaction with Aries City after it has reached a certain stage.

Colin, who has access to a large amount of phantom potions, has already mastered the code to wealth, and he is eager to transform these things into strength.

Colin returned to the wizarding world and quickly brought the Shadow Potion to the Emerald Island.

After returning, Colin once again convened a meeting with his family. The topic of the meeting was whether to promote the phantom potion, mainly because the benefits involved were too great.

Although Colin had traveled to and from the phantom world many times without any incident, Hathaway had doubts from the beginning about the phantom world's method of improving strength. After all, Colin was affected by an unknown influence when he suddenly entered the phantom world for the first time.

Although the other women valued their own interests, they paid more attention to Colin's safety. When he ate the phantom creatures to enhance his mental strength, he had to consider the interval time and pay attention to the amount of food he ate.

It is hard to say whether large-scale hidden dangers will arise if the supply of phantom potion is released.

In the end, Hathaway's opinion prevailed. She hoped to bring the junior, middle and senior three levels of phantom potion back to the floating city and have them identified by Master Merlin. If there were no hidden dangers, with the help of the floating city's influence, the phantom potion could be quickly promoted to the entire wizarding world.

It should be said that it is good to have a cheap master, and it would be a waste if you don’t use him.

After confirming it, Colin and Hathaway set out for the floating city again.

……

"Teacher, this is the shadow potion that Colin brought back." Hathaway said after handing the potion to Merlin.

"You, kid, really gave me a difficult problem. If it weren't for Hathaway, I wouldn't bother with you. This kind of opportunistic method must have some hidden dangers.

For example, why does the effect of mental strength potion gradually decrease after each use?

This is the resistance reaction produced by the body. As you said, your phantom potion does not produce resistance every time?

If we have enough resources, after exchanging them for a large amount of phantom potions, can't we create gods in batches?" Merlin said with regret.

"Well, Master, although I haven't used the phantom potion in the past few decades, I didn't have any adverse reactions after consuming the crystal cores of phantom creatures, so I didn't think too much about it..." Colin said defensively.

"Okay, you and Hathaway stay in the floating city for a while. I'll also see how the powerful people in the spiritual world play. Also, how many of these things do you have on hand? Take them all out. One bottle may not be enough for testing." Merlin said without hesitation.

"Uh, okay." Colin's idea of ​​making a fortune was now overshadowed, and he even began to doubt whether he should go to the phantom world to hunt again in the future.

……

Colin and Hathaway were a little bored after leaving the holy tower. They didn't know how long it would take Merlin to come to a specific conclusion, but they didn't dare to leave. If they returned to Emerald Island and Master Merlin just came up with the results, you wouldn't be there?

Well, you dare to let a fourth-level strong man wait for you, do you think you are too shameless?

Although the next half month was a bit boring, Colin still followed Hathaway to visit some special talents in the floating city.

Some are good at making alchemical tools, some are good at academic research, and some are good at body transformation.

As Merlin's disciple, Hathaway has gotten to know quite a few people over the years. This time, while waiting for the results, she also helped Colin expand his social circle.

Although you can't see anything at the moment, after all, you have just been promoted to level three and you don't have much value yet, but it is still beneficial to show your face and make yourself familiar to others.

Merlin finally came to his conclusion. After calling Colin and Hathaway back to the Santa again, Colin realized that he had indeed thought less.

“This kind of phantom potion is indeed harmless if taken in small amounts. Similar to the mental potion, it can indeed enhance the mental power of the user, but it is more effective on low-level professionals.

As the dosage of the medicine increases, the connection between the spirit and the body will gradually become fainter and distant, and slowly your spirit will exist apart from the body, and eventually you will never be able to return to the original world.

In other words, this is a way for the spiritual world to increase the number of spiritual creatures, especially for highly powerful professionals.

Not only that, some users will be forcibly dragged into the nightmare world, which is much more dangerous than the spirit world. It's not just about becoming a spirit world person, but also about facing all kinds of weird things. If you can't hold on, it's only a matter of time before you completely perish."

"Ah?" Even though Colin was already at level three, he was still a little stunned. This was too scary, a conspiracy from the spirit world?

Take the high-level combat power from all the heavens and worlds for your own use, and then release the traction stone again to lure new victims?

This is such a scam, who came up with this wicked trick?

mine.

Seeing that Colin finally realized the harmfulness of the Shadow Potion, Merlin smiled and said, "However, I have found a way to control this harm and make the Shadow Potion a beneficial potion that can be taken safely for a long time."

After hearing this, not only Colin, but Hathaway also began to resent the teacher's manipulation of people's hearts.

"Teacher, you are too..." Hathaway said coquettishly.

"Too what? If I don't scare you a little, how can I get your attention? Last time you mentioned Colin's trip to the phantom world, I had some doubts. An incomplete world like this, located at the intersection of the spirit world and the nightmare world, must be the product of the union of the strong men from both sides.

And it must be driven by the common interests of both parties. I don't know how much manpower and material resources were spent. How can you, a guy who suddenly broke in, find such a good thing? Where are those people who entered earlier than you? Don't even think about it!

I'm very optimistic about you, but don't let me down. Okay, I can solve the subsequent hidden dangers, but you can't scatter this medicine outside at will. Hathaway will be responsible for this matter from now on. You will get 30% of the profits after deducting the losses."

Well, now I have to cooperate even if I don't want to. I don't have the ability to eliminate the hidden danger. After deducting the cost of purchasing mental power potions, can I get 15% of the phantom potions after exchanging them?

At this moment, Colin not only took Merlin's warning seriously, but also had a question mark over the fortune he had expected to make this time.
