The talk with the professor gave much for Mack to think about, but he had a fight in the next day, and because of that he didn't stay with the professor much longer, he got the meditation technique, a quick explanation about the dantians, and a bit more of information about cultivators.
Mack knew it was only the beginning of his 'lessons' with the professor, but it was a good start. He never expected to learn anything inside the Fenryr Tower, but that was life. A few choices, and unexpected things happened.

In the next day, Mack woke up as soon as the sun came, and started practicing the meditation technique. He knew it would take time to see any changes, but the sooner he started, the better.
After a few hours of meditation, Mack stopped and as expected didn't feel any different, 'The start is always the worst' thought him, remembering his early days inside the tower because it was very similar to what he did to break the gates inside his body.
