Apart from the Transcendent Martial Arts, Ling Xiao could take a look at other books, including Astronomy and Geography, as well as various amusing anecdotes and observations.
Advanced Martial Arts in the outside world are the dream of all Martial Master Realm experts, including those at the Martial Pulse Ninth Level.
But here, Ling Xiao could freely review Advanced Martial Arts, which was probably the biggest benefit of becoming a disciple of a Transcendent Warrior.
However, although he could consult and learn from these Martial Arts, he was not allowed to take any of them out.
Of course, this restriction was not very significant to Ling Xiao since he could easily copy any Advanced Martial Art he picked up.
After reading the introduction, if he was interested, he would look at it a few times more; if not, he would just throw it back since the copying was already finished.
In the pursuit of Martial Arts, one must not be greedy for too much.
