A new day had arrived, and not long after Erbach had started work, Charles came to the principal's office.

"Sit down first, I'll sign a few papers. The principal looked at the documents and said, "You went to the epidemic area, how is the situation over there?"

Charles had reported to the principal in advance that he was going to the epidemic area for a meeting, and he gave a general overview of the situation there.

Professor Erbach was relieved to hear that everything was getting better, and he watched the movie several times a while ago, and every time he watched it, his heart was heavy.

He asked, "Do you think there's any way to prevent something like this from happening?"

Charles thought for a moment and said, "My suggestion is to refer to the waterworks in Slime City in the Slime Basin, now that Slime City has popularized running water, all residents in the city have access to clean water." ”

In addition, the farms in the basin are also promoting small water purification plants, which can also be used as a reference. ”

Elbach nodded and asked, "Do you think our academy can design a factory like that?"

Charles immediately replied: "Of course, I designed the waterworks, and the small water purification plant has been used in my maple sugar refining plant for hundreds of years." ”

Professor Erbach looked up at him, shook his head and smiled, "Don't you say I forgot, I went to your house to play when I was your age, and I also went to see those pools once, and I thought it was boring to take a look at it and came back." ”

Charles said: "I'll donate the design of the water purification plant to the academy later, it's not an important technology anyway." ”

Professor Erbach thought for a moment and said, "You might as well publish it in the journal Magic, the impact of this plague is very large, so it can be reassuring." ”

Charles thought for a moment, then nodded in agreement. "I'll publish it in next month's magazine, it's too late this month," he said. ”

"Besides, if my paper is published for two months in a row, some people will gossip if it is found out later. ”

After signing the paperwork, the old headmaster put down the quill, looked at the guy with interest, and asked, "How did you discover the purity of the elements? ”

The final paper in the inaugural issue of Magic magazine was Charles's "Research on the Differences in Natural Magical Elements in Different Regions and Speculation on the Characteristics of Magical Elements", the author was only "Charles", and did not write a surname, although Charles later mentioned it to the principal.

Charles smiled and said, "Just like in the paper, there is a difference between the water element by the sea and the water element elsewhere. ”

Professor Erbach didn't go any further, he took out two rolls of parchment, and said, "I have an old friend in the south who has a big cave in his territory, which has been occupied by vampire bats in recent years, and he told me to find someone to fight against it. ”

Charles took the parchment and opened it to see that one was for the Territory Steward to cooperate with the Raiders, and the other was for the Batcave.

After reading it, he gasped, the entrance of the cave was dozens of meters high, and it was deep into the ground and meandered I don't know how much distance, it must be more than a few kilometers.

I don't know how many vampire bats with a wingspan of half a meter have occupied it during this time? When evening comes, dense bats fly at the entrance of the cave, and it looks like a dark cloud from a distance.

The surrounding villages have suffered, and livestock continue to be sucked to death by vampire bats? There were several caravans killed in the field, and no one dared to go there to do business anymore.

The most troublesome thing about this mission is that there are too many vampire bats, and the cave entrance is very large? There is no way to use the tactic of blocking the door.

If a few people or even dozens of people passed, and the overwhelming number of vampire bats rushed over from all directions, if there was no large-scale magic? It's hard to exert your strength.

The local lord is powerful though? But he lacks mass magic as a means of attack? So it's okay with these bats.

However, this is not a troublesome matter for Charles, and it can be solved in half a day.

What did he care more about the cave? By process? There might be something good in there waiting to be picked up for yourself.

"I took the task. Charles accepted the parchment roll, "Shall I leave later?" If there is no accident, a day passes, and the task is completed in one day? Come back one day. ”

Professor Erbach is not surprised that he can solve the problem in one day? Want to come when this "vegetative man" planted pea shooters around the cave? Plus a couple of corn cannons? No amount of vampire bats was enough for him to eliminate.

Some people tried to learn this magic from Charles, but he refused to do so on the grounds that it was a gift from the gods.

After taking the task, Charles left the office, he didn't pay attention to this small task, and came to the airport after talking to an acquaintance.

With the resumption of air routes, there are far fewer transport planes that used to transport and replenish the knowledge city during the flight outage.

The temporary landing ground outside Nanhai Farm has been abolished, and now only an airport built on the vacant land vacated by the demolition of warehouses to the north of the port area has been officially upgraded to a permanent airport.

At present, the airport is mainly passenger traffic, and there are currently four direct routes to Bosnia and Herzegovina Airport, Slime City Airport, Sepas City Airport, the royal capital of the Kingdom of Relik, and Charles Family Territory Airport.

There are many people who are interested in airports now, but how to repair the airport depends on the plans of the airlines.

Charles flew to Slime Basin on a soliciting transport plane that took off at noon, and it prospered a lot because of the opening of air routes.

As soon as he got off the plane, he found the dragon flight and flew directly to the town near the Vampire Bat Cave.

When the dragon brother knew that he was going to that place, he made a goosebump look and asked, "What are you doing in that place?"

Charles said truthfully: "I'm going to hunt down the vampire bats there." ”

Brother Dragon patted him on the shoulder and said, "If you kill those bats, I'll give you a twenty percent discount when you come back." ”

Charles asked curiously, "What, are you afraid of vampire bats?"

"We hate vampire bats as much as you humans hate mosquitoes, you see. ”

Charles nodded, understood.

The dragon brother is very talkative, and he tells Charles a lot about vampire bats along the way.

When their dragons need to sleep for a few months, they tend to find a cave in an inaccessible place as an outing or something.

Monsters don't dare to approach when the dragon sleeps, but vampire bats are different, for them, the temptation of the dragon's blood can easily overcome the fear of the dragon's might, which makes the dragon annoyed.

Charles had to marvel at how amazing the world was.
