Su Mo did not find any trace of the enemy, and the Palace-protecting Formation was not attacked again after a long time, so he returned to the Firmament Palace.
"My Palace Master!"
The instance Su Mo flew to the front of the Thick Earth Pavilion, Gold One, Fire One and other puppets came up to him.
"Pay attention! Once the enemy appears, inform me at once!" Su Mo instructed.
"Yes, Palace Master!" several puppets responded.
Su Mo nodded his head and entered the Earth Palace to embark on cultivating.
During his cultivation, Su Mo did not forget to pay attention to the Palace-protecting Formation outside. If it suffered aggression a second time, he would immediately strike back.
However, Su Mo was apparently too scrupulous. The Palace-protecting Formation was not under attack within next ten days.
Thereupon, Su Mo immersed himself in cultivation.
