Chu Nan thought of a document he had seen many years ago when he had just cultivated martial techniques and was at the stage where he was most interested in studying martial techniques.
According to the information, apart from a small number of S-rank martial techniques that the martial artists of the Earth Federation had created themselves, most of the remaining S-rank martial techniques were actually obtained from other places through other methods.
Among them, the most common method to obtain an S-rank martial technique was through the Declan Empire.
The Declan Empire indeed had a tradition in this aspect. Apart from holding the Garden Hunting Assembly every once in a while and giving some cultivation methods that were originally unique to the Declan Empire to the young martial artists of other countries as a reward, they would also hold all kinds of other activities and spread the cultivation methods through some special methods.
