Zhou Tian's aim was to gain some benefits, and if at that time he could have cleaned up the divine corpse bones in that flat ground, then it's believed that the benefits he would receive would surely be considerable. Moreover, if he obtained the treasures left behind by the deities in that flat ground, Zhou Tian wouldn't have needed to continue the fight with that blood monkey.
So, when Zhou Tian realized that the blood monkey did not intend to attack him again, he immediately rushed towards that flat ground. Based on the situation at the time, it seemed Zhou Tian was planning to first clean up the divine corpse bones in the flat ground, and then consider whether to continue the combat with the blood monkey.
