ALO completely inherited Sao's data. As for the reason, we can refer to the "experiment" mentioned by Su Xiang Nohiko in the latest sentence 17.
Tongren's data has also been inherited to ALO.
Therefore, the essential parts of the data, such as the value of proficiency of one-handed sword, are also completely inherited.
However, due to the different world outlook, most props have not been inherited, because what exists in the Sao world does not necessarily exist in ALO.
Similarly, it will be mentioned later that some things that are hidden in ALO, such as enemy tracking and other skills that ALO itself does not have, are also learned in SAO, and will also be displayed after inheriting from ALO.
Therefore, in ALO, the Dong people were very strong from the beginning.
