The Witcher: Son of the Planes.

Colin has not returned to the academy since he left it a few years ago. On the one hand, he is no longer considered a wizard of the academy. On the other hand, there is nothing to do if he goes there. The academy library is not open to him. He doesn't care about anything else.

Five years is a very short time, so short that Rodbell might not even think of him. Perhaps one experiment might take several years for others. Colin took the initiative to show his goodwill before leaving the academy just for the sake of socializing. He didn't care if no one looked for him. But this time Teacher Lina looked for him, it seemed that she had something to do, and he didn't forget about the hundred-year contract.

This time I entered the academy because of Lina's invitation, but I still had to register at the entrance of the academy before I was allowed to enter.

After passing through the familiar college road, they soon arrived at the Holy Tower, but Boggs was already waiting there.

"Hello, Master Boggs."

"Well, it's been a long time, Colin. Let's not waste time talking and go upstairs first. We'll talk again when we have time." After that, Boggs took Colin to the 73rd floor of the Holy Tower.

……

After entering the reception room on the 73rd floor, Colin discovered that in addition to Teacher Lina and Jaina, there were two male wizards and one female wizard.

After greeting Lina and Jaina first, Colin just nodded to the three wizards as he was not clear about the situation of these three people.

Seeing that everyone was recognized, Lina actually started to prepare a spell. Colin didn't know what Lina was doing, but after the spell was cast, there was no change.

"What we just did was an isolation spell, which can prevent others from detecting our conversation."

"Oh, I don't know this little spell yet." Colin thought to himself.

"I called you back today because I have something to tell you. Colin, you may not know them, but these three are your senior brothers and my disciples."

"Ivan, Ulman, Falsa, he is the junior brother Colin I mentioned to you."

"Colin, you don't know, but everyone else knows that your uncle and I signed a 183-year agreement with the academy. Now 17 years have passed. In another years, Jaina and I will be free, and by then we will no longer sign an agreement with the academy."

Having said that, Lina paused, as if letting her four disciples digest it.

Then, she continued, "Your uncle and I are from the Mogwen region of the main continent. Due to fierce competition among local families, we had to travel far to the South China Sea to study. Fortunately, we sisters are lucky enough to have come this far."

"But with my successful promotion, several messengers from the family have come, hoping that I will return to take charge of family affairs. Our Seaton family is no unknown family in the Megwen region. Our resources and corresponding knowledge system are no less than the libraries of some forces. I say this because I hope that you can return to the family with me and serve me."

"Of course, this is not a mandatory order. I am just asking for your opinions. Even if you have different opinions, I will not blame you."

After finishing speaking, Lina waited for everyone's response.

Colin had no objection. He had sold himself to the company for a hundred years, and only five years had passed. He couldn't deny his obligation, so he just had to serve.

However, his three cheap senior brothers seemed to have considered it for a long time.

But since the teacher asked, I had to answer.

As the eldest senior brother, Ivan expressed his attitude first. "Teacher Lina, I have no plans to join other forces for the time being. If it is not mandatory from your side, I can be your disciple and help you deal with some family affairs, but I have not considered joining your family for the time being."

"Well, is this half agreed?" Colin thought.

The second senior brother, Ullman, also followed suit and explained his decision: "Teacher, you know me. The Blanche family (Ullman's wife) helped me a lot in the early years, and they helped me a lot when I was promoted. I really can't leave and join your family, but if you have something to do, I will definitely support you."

Finally, the third sister, Falsa, was left. She said simply, "You two, if the master hadn't accepted you as disciples when you were in the academy, you might not have come this far even if you had the resources to help you. Now you are making excuses for the little things. Forget it, I won't rely on you two. Brother Colin and I are enough."

Ivan and Ulman shook their heads helplessly. This little junior sister is just like that. She thinks things are either black or white. It’s not that we don’t want to help the teacher, but we have our own difficulties. Alas…

"Teacher, I agree to join." Farsa said firmly.

"Okay, everyone, stop arguing and don't feel guilty about anything. Everyone has their own ideas and their own practical situations. All good things must come to an end. However, it's great that Ivan and Ullman can help the teacher deal with some things."

"You are all here today. As a teacher, I will tell you about my feelings after being promoted to Level 2. It can be regarded as a farewell gift."

After that, Lina took the initiative to tell about her promotion to the second-level semi-elemental fire wizard.

Teacher Lina’s three disciples are not all fire wizards, but they can draw inferences from one instance to another and it is still somewhat inspiring for them.

That was really helpful to Colin. Although he didn't understand some of the content, he still wrote it down carefully and saved it for later study.

The gathering of all the disciples that Lina had gathered together was over.

After adding the contact information of the three senior brothers, Colin said goodbye to them and returned to his residence.

The girls who were waiting for Colin were curious about what his teacher wanted to talk to him about when they saw him come back.

Colin briefly described Teacher Lina's intention. Because of the contract and Colin's own limited network of contacts, he was still willing to follow Lina's family. Wouldn't he be able to gain more resources and knowledge this way?

The girls were all fine with Colin's decision. It looked like within 17 years, they would either be promoted and leave the academy, or drop out and become an apprentice.

The gathering in Lina's living room did not have much impact. Many people were not aware of Lina's ambitions. However, many wizards in the academy were just coming and going, and very few of them actually stayed in the academy for their entire lives.

After the party, Colin officially joined Lina's forces, and gradually had more contact with his uncle Jaina. His uncle was also a water wizard and had a lot of experience in ice magic. Her promotion experience could serve as an important reference for Edith.

Jaina knew Colin's little thoughts, which was to seek some benefits for her little wife. As her sister's disciple, she was also one of her own. After Colin completed several of his tasks, Jaina gave Colin a copy of her sorted promotion experience as a gift.

Colin and Edith were overjoyed when they got it. Except for the ice element's heart core, every step in the promotion was important. Edith didn't have an earthling to help her like him. If she failed once, the next time would be even more difficult.

……

In addition to studying experiments, Colin would keep in touch with the members of the South Sea Hermit Society when he had time, and play with the girls when he had more time. He had a good life.

Two years passed like this, and 15 years before Lina left the academy, Lina arranged for Colin to go to her family first to deal with something.
