Alex had been instructed by the system on how to control his soul and how to defeat the two consciousnesses.
So, Alex sat on his bed and entered his consciousness. He went back to the special soul realm again and looked at his soul. He also observed the Sword and Spear consciousness. They would not attack him before he attacked them, so he could get accustomed to his Soul first.
