After Su Mo went back to Huo Yuan Peak, Grand Master Huoyuan let him return to his immortal's cave without giving him any further instruction.
Su Mo immediately went into the Bangle Space and started cultivating when he reached the immortal's cave.
For this trip to the True Sage Territory, Su Mo not only had to leave his name on the True Sage Stele, but the Sorcerer Tribe wanted to kill him and thus it was filled with danger. This gave him excessive pressure.
Moreover, as he had been ranked number one on the True Sage Board, there would be more people setting themselves against him.
Thus, he had to make good use of every second that he had to enhance his strength.
