Judging by the Sun Moon Empire Royal Soul Guidance Device Academy's current level of progress, the thing in He Caitou's hands had long since been improved into an exquisite device roughly one meter in length and ten centimeters in diameter.
Moreover, the inscriptions on it had already incorporated Soul Guidance Arrays for cooling, heat dissipation, and energy gathering.
It would not be like the crude thing in He Caitou's hands, which was not only difficult to carry but also lacked endurance.
However, Huo Yuhao did not reveal any of this, lest Teacher Zhou and her little boyfriend notice anything unusual.
Playing the part of a well-behaved child, Huo Yuhao watched as He Caitou skillfully held it in his hands. After pressing twice behind the metal tube with his right hand, a cover immediately popped open, revealing an opening around twenty centimeters long and ten centimeters wide.
He then swiftly patted his waist with his left hand, and a spindle-shaped piece of metal appeared in his palm.
He carefully placed the spindle-shaped metal into the opening exposed by the opened cover of the metal tube, then closed the cover again.
With a lift of his right hand, the metal tube rested upon his broad shoulder.
"Sure enough, this thing's operation is still stuck in ancient times. It's garbage among garbage."
Huo Yuhao sighed. If he entered the Soul Guidance Device Department to study in the future, he decided that he would seek Sister Wan'er's help more often instead of turning to Shrek's Soul Guidance Device Department teachers.
At this moment, the previously simple and honest-looking He Caitou underwent an instant change in temperament the moment he shouldered the metal tube.
Huo Yuhao's martial soul possessed a spiritual attribute, and his acute senses allowed him to feel intense excitement from He Caitou.
