After checking his status, he began to focus on refining his chi. The greatest weapon he currently has is his chi and domain. As long as he has the chi, he could deflect or reflect any kind of attack using his domain.
With this, he is sure to survive in the Endless Battlefield. So, his current focus is to refine chi and increase his reservoir as much as possible. As for his other attributes, he could only leave them for now.
Even though he focused on gathering soul points during these two months, he could only increase them by one or two points, which practically didn't significantly affect his power and survival rate.
Angus also feels the old man Draught is right. The most important thing is to get out alive. It means he needs everything to increase his survival, whether from his personal strength, potion, item, etc.
