In Su Jinran's generation, only Su Ningxiang qualified to enter the Forbidden Land for training and she managed to come out alive.
However, aside from Su Ningxiang, two other core disciples also entered the Forbidden Land, but eventually did not make it out alive.
Su Jinran recalled Su Ningxiang mentioning that the deeper one went into the Forbidden Land, the more poisonous plants there were.
Moreover, higher-level herbs were often accompanied by fierce beasts.
Those beasts were extremely ferocious, and without sufficient strength, one could not survive the Forbidden Land.
When Su Ningxiang emerged, she was barely breathing and covered in wounds, and it took her a whole month lying down before she could walk again.
Because she successfully came out of the Forbidden Land, Su Ningxiang's position as the Young Family Head became even more unassailable.
