Cultivating a psychic barrier isn't an overnight job; it requires long-term training to increase proficiency. It's going to be a good half month before Tang Qing can use it with ease and at will.
Then there's another skill.
It's called 'Magnetic Resonance'.
As the term implies, it's related to magnetic fields.
The main idea is to sense magnetic fields to achieve interaction.
For example, Tang Qing once thought that if his nerve telekinesis became powerful enough, he could lift himself up and glide freely in the sky. He tried once before and managed to slow down his falling speed, but 'Magnetic Resonance' completely subverted his previous view.
It turns out you don't have to use nerve telekinesis to lift yourself up and fly; instead, you have to sense the planetary magnetic field, establish a connection, stimulate the psychic force to interact with the magnetic field in some manner. There's an easy way to understand it - it's anti-gravity.
Yes, it's anti-gravity.
