Jian focused on recovering his injuries while Song Yu, whose injuries are healed, was sitting and relaxing.
They have successfully cleared the second part of the tomb. They even have gotten the instructions for going to the final part of the tomb. But before that, Jian had told Song Yu to recover to top condition.
It has been one hour since Song Yu has completed recovered. Now she is waiting for Jian to completely recover and then going to the last part of the tomb.
To go to the last part of the tomb, Song Yu have to eat the Thunder Fire Spirit Fruit, and as she finishes eating the fruit, she will be Teleported to the last part of the tomb.
Song Yu had said that she felt to devour the fruit whenever she saw it. Jian was shocked at first, but then he thought it related to her being a Heavenly Warrior.
