I recommend you to play Qingyun Mountain, Yijinjing, wash your mental strength low and attack high, use meteor boxing and dragon madness skills. It's amazing. When using marrow washing pills, look at the difference between the peak attribute and your basic attribute. It is best not to use it within 5 o'clock, otherwise it will be eliminated. Use the sky-mending stone on the legendary equipment of Qinglong and Suzaku, because the fragments of Qinglong and Suzaku are easy to get.
The difference is too small, it is best not to use it.
