All students in the Tower of Wonders were assigned jobs, and Moore's class even allowed students who did not perform well in the exams to exchange work points for academic credits in order to avoid the cost of retaking the exam.

Lower-level machinists can only take on the task of manufacturing and laying cables, while the key shooting and playback devices are the responsibility of higher-level machinists.

Although Carl was the inspiration provider for the Phantom Device, his rank was still low, so he and his classmates were all assigned to build a cable production line.

It wasn't until the winter vacation approached that they built three production lines.

The fully automated production line can produce several meters of cable every second. The teachers have also set up devices to detect damage to prevent problems with the produced lines.

Then, winter vacation came.

…

"Goodbye, Master!"

At the port of the artificial island of Akanix, Carl and a group of rangers from his hometown waved goodbye to Mooreban on the shore.

Considering that he might be caught by his master and forced to do hard labor, Carl went straight home under the pretext of "returning with an exchange student".

And those poor senior students continue to stay in school and contribute to the Nine Paths Competition.

"Brother Karl, you just came back like this, aren't you afraid that Professor Moore will be angry?"

Looking at Mooreban who was pointing at the ship and cursing on the shore, Lisanna wiped the sweat from her forehead and asked in a breathless voice.

They ran all the way here and arrived just one second before the cruise ship weighed anchor.

Even though the rangers have plenty of stamina, playing like this is still a bit stressful.

"It's okay. Don't look at him like this. He's just pretending. If he wants to keep me here, how can this cruise ship stop him?

If I don't run, how will those students who are anxious to go home have an excuse to leave? The tower owner is really something, he actually wants to finish the work ahead of time."

There are rumors that the tower master has an unclear relationship with Queen Aundair, otherwise he would not have taken over the mess of the Magic Council's deficit.

Carl and his fellow disciples were not sure whether this was true or not, but the tower master's anxious attitude made the rumor that had been circulating in the Tower of Strange Machinery seem a lot more real.

Anyway, they have never seen the tower master being so concerned about orders from other countries.

Lisanna nodded as if she understood, and took out the imitation 98K made by Carl from her dimensional bag.

During this month, Lisanna took it out to practice when she had nothing to do.

Carl later made her an eight-fold scope and other accessories.

By now, Lisanna is already quite familiar with this "gun".

The two ranger instructors preferred the imitation AK rifle.

After all, they belong to a ranger squad that fights at medium range, and rifles are much more useful than bows and sniper rifles.

After drifting on the sea for most of the day, Carl and others arrived at the city of Wana in the afternoon.

So, Carl finally returned to his home which he was forced to leave after sleeping for only one day.

"Is this definitely my home?"

Standing at the door of his house, Carl looked at Hope who was cooking with his parents in the yard, and confirmed with Lisanna beside him.

These three people are more like a family now.

"Hey! Why are you jealous? Aunt Elifel! Uncle Ryan, Brother Carl and I are back from vacation!"

Carrying a sniper rifle named "8000 Life Shots", Lisana ran happily into Carl's yard.

When they arrived at the port just now, a police officer who knew Lisana's parents told Lisana that her parents had returned to Bixin City.

This is how the two met when they were children. At that time, Lisanna's parents stayed on the front line in the Devil's Wilderness for a long time, and she played outside all day without anyone to care about her.

After a long time, she became dirty and some children didn't want to play with Lisanna anymore, so Carl took her home and let his mother take care of her.

After a few visits, the two families became familiar with each other.

"Oh! Baby! You look so thin, have you been suffering in school? I heard from Karl that the food in their school is very expensive!"

When she saw Lisanna, Elifel immediately hugged the daughter she had raised since childhood.

Carl standing aside had his eyelids drooping, enjoying the treatment of being ignored as a biological son.

"If you like daughters so much, why don't you have one yourself?"

Muttering quietly, Carl put his and Lisanna's luggage into the house.

Carl's father was roasting a lamb.

As a priest of the God of Forging, he has a very precise control over the temperature of fire.

The whole roasted lamb has now been roasted to a golden crispy skin, paired with wild leek sauce and a little spice... Wow! The taste is simply amazing!

"Come here! Big son, try daddy's cooking!"

Seeing his son coming over, Ryan was unusually enthusiastic.

After cutting a piece of fragrant ribs from the roasted whole lamb, this middle-aged man, who was over two meters tall, had a flattering smile on his face.

"Dad, don't be like this. Tell me what happened. I'm a little scared when you laugh like that."

Carl took the ribs hesitantly and dipped them in dry sauce to taste them. He was intoxicated by the wonderful taste of fat and protein.

"Well, I won't keep you in suspense. Son, I heard that your Tower of Wonders and Queen Aundair have reached a big deal. How about it? Can I, your father, get involved?"

Taking a half step back, Carl looked at his father again.

"Sure, Dad, you're well-informed!"

"What the hell! The rumors are going viral! The tower master of your Tower of Wonders is bringing a group of Level 10 Wonders build something in front of the gate of Venern University. With such a big commotion, everyone must know that you have come up with something new!

Don't forget that my father-in-law, your grandfather, is a history teacher at Vinern University. He wrote to me as soon as your tower master brought people there.

But you! You don't care about your father's business at all!"

Upon hearing this, Karl immediately rolled his eyes.

"I was the one who came up with the idea for their project. Dad, this job is too delicate. You can't do it!"

The prototype machine made by Moore Class and a group of teachers is about two meters high and half a meter wide.

The magic patterns inside the device are quite tight, and unless there is a breakthrough in related technology in the future, the overall structure will not change much in a short period of time.

Carl's father's weapons business mainly deals with magic weapons.

These weapons do not have very high requirements for the size of the magic patterns, or in other words, larger magic patterns can make the effect better.

The technologies of the two are in completely different directions. Carl's father couldn't drink any soup with this new invention.

Just as he was about to have another piece, Carl suddenly remembered something, then looked at his father who looked disappointed, and asked, "By the way, since my grandpa is a history teacher at Venern University, can he write scripts?"
