After Zhao Hai saw these notes, he understood why the Robert family placed so much importance on them. It was because these notes were none other than the training experiences left behind by 9th rank experts!
The training notes left behind by a rank 9 expert were definitely valuable. It might not be of much use to Zhao Hai, but it would be of great use to Grimm and the others.
Grimm, Merlin, and kon Zheng had all reached the peak of the 8th-level, only one step away from the 9th-level, and these cultivation experiences could provide them with some insight.
Zhao Hai now understood why it was so easy for large clans to produce combatants of the ninth rank, while it was very difficult for small clans to produce such combatants. What they lacked was probably this sort of cultivation experience.
