The Witcher: Son of the Planes.

Helen had taken pharmacy courses, but the magical materials in the Victoria Islands and the wizarding world were different. She needed to re-recognize these materials and identify and remember their medicinal properties.

After spending 20 merit points, Helen added a new pharmacy course in addition to the daily open classes.

The course is just an introductory course, mainly talking about the commonly used plants in the wizarding world and the uses of some magical beasts' organs. At the end of the course, there are two basic recipes, which can be regarded as a benefit given by the academy to students. One is the recipe for basic mental power potion, and the other is the recipe for basic physical power potion.

But having a formula does not necessarily mean you can prepare the medicine; you still need to keep trying, experimenting, and practicing.

After successfully refining, you still need to continue to delve into the details. A higher success rate can ensure that you do not lose money.

Helen is undoubtedly smart and knows what is mainstream. Although she can also learn the formula of mental potion in the Victoria Islands, some materials may only be available in the Victoria Islands and are not very applicable.

Because she was determined to come to Grimaldi Island, her family's expectations, and her fantasies about the future, Helen knew that she had to make a name for herself on the path of a wizard.

Why does my partner frequently take on tasks? Doesn't he want to study peacefully in the course? No, he wants to, too.

But the actual situation now allows me to only study alone first. The family will probably send a batch of medicines in half a year, but I can't delay for half a year.

……

"Connie, you're here." Colin, who got up early today and was waiting outside the mission hall, greeted.

"Well, you're here early."

"No, I just got here a while ago. Let's go in together."

Browsing the familiar task screen and looking at the scrolling tasks, these are the tasks that no one has accepted yet.

"Hey, a mission to investigate the missing slaves in the Barna Mine." Colin discovered the mission.

"how about this?"

"Try it," Connie replied.

Soon the three of them accepted the task of investigating the missing slaves.

To be honest, after I accepted the call, I found out that the location of this mine is a bit far away. It is outside the town of Barna and about ten days' journey from the academy. But when I saw the reward of 100 merit points, it was worth it.

I left a message for Helen saying I would be away for a while, and Helen replied telling me to be careful.

Colin and Connie, brother and sister, rushed to the town of Barna.

……

Ten days later, Colin and his two companions arrived at the town of Barna, exhausted. After meeting Baron Lesta, the mayor of Barna and the person in charge of the mine, they learned that a group of wizard apprentices had come to the mine some time ago, but returned after finding nothing, apparently without finding the reason.

After dozens of slaves disappeared in succession, the Barna Mine also stopped mining operations. It was also because of the failure of the first exploration that the task was increased from 50 merit points to 100 points.

Colin and the other two looked at each other and felt that the situation was a bit tricky. They were not much stronger than the others, but since they were already here, they had to give it a try.

Baron Lesta received Colin and the other two and prepared to go down to the mine to explore the next morning.

The next morning, under the forced drawing of lots by Baron Lesta, a slave was appointed as a guide to lead Colin and the other two into the mine for exploration.

……

The slave who led the way was called Billy. He said he came from a small world called Palo. He didn't know when his home planet was enslaved by the wizarding world, but he was born in the wizarding world. Since he had no special combat power, he could only mine.

Thinking of this, Colin felt a chill in his heart. Fortunately, the Victoria Islands were integrated into the wizarding world. If they were enslaved, wouldn’t that be even more miserable than when he first arrived in the Victorian world?

The mine outside the town of Barna mainly produces mithril. There are more than 500 slaves in the mine, which can produce more than 4500 tons of mithril per month, most of which must be handed over to the Gliman Wizarding Academy.

As the producer, haha, only a few dozen tons can be left, but even so, Baron Lesta is very happy. However, he has not been able to complete the task for a month, which also makes him worried.

Since the wizard apprentice didn't find anything last time, he arranged for the slaves to go down the mine again, but the slaves disappeared again soon after. He had no choice but to continue issuing exploration missions.

Billy held a torch and led Colin and the other two deeper into the mine. The faint light of the fire illuminated the road ahead. It was quiet inside the mine, and occasionally a whistling sound like wind blowing into the mine could be heard.

The four of them moved forward slowly. Colin had already grasped the iron spear tightly, and Connie and Conrad were ready to cast spells at any time.

……

"It's here. There are traces of the blood of missing slaves here. The minerals here are easier to collect. We also have a mission. We need to collect 300 kilograms every day. If you fail to complete it, you will not be given food." Billy said.

Colin and the other two observed and did not find anything unusual, but this was an intersection. In addition to the direction they came from, there were three other directions where they didn't know where they led.

"Where do these three directions lead to?" Conrad asked.

"I've only been here. I haven't been to the other three directions. Those missing people should have been there." Billy replied.

"What should we do? Should we go separately? Or should we explore in one direction first?" Colin asked Connie and her siblings.

"I think it's better for us to go together. After all, if we encounter danger, more people means more strength. Even if it takes a little more time, it's better than being unable to deal with the danger." Connie analyzed.

Colin and Conrad looked at each other and realized that there was no better way, so they followed Connie's idea, found the road on the left and started moving forward.

Billy had no say and could only helplessly continue walking in front with the torch in hand.

The road ahead was rugged and had many bends, uphill roads, downhill roads, and some sections were flooded. However, the road was relatively flat and no special circumstances were found. Connie recorded everything she saw and heard on the road.

Soon, the four of them reached the end, which turned out to be a dead end. After observing for a while, they found nothing and had no choice but to return.

The return trip was much faster, taking less time than the trip there, and the four of them returned to the intersection.

"How do we get there?" Colin asked, looking at the remaining two roads.

"Let's go one step at a time. We have to complete this exploration at all costs," Conrad said.

The four of them started walking towards the middle road. The road in the middle was longer and had more bends than the road on the left. They also encountered a few scattered scorpions and rats, but they were nothing to Colin and the other three. Billy could kill these small animals easily.

After passing the middle road without any trouble and without discovering anything, the four of them returned to the intersection again.

"It looks like the only road left is the one on the right. If the problem isn't here, then our trip will have been in vain," said Colin.
