In just half an hour, the system has already lost the temporary power boost from sacrificing the Core Disciple's cultivation base.
Taking that opportunity, I quickly use my chaos qi and spiritual qi to destroy the defenses on the Core Disciple's Soul Dimension that was built by the system.
Since the system has lost the temporary power boost, despite the system's resistance, the defenses on the Core Disciple's Soul Dimension became weaker and weaker as it was continuously attacked by my chaos qi and spiritual qi.
After a minute has passed, my chaos qi and spiritual qi have torn a hole in the Core Disciple's Soul Dimension's defenses as my chaos qi and spiritual qi enter the Core Disciple's Soul Dimension.
The chaos qi and spiritual qi that entered the Core Disciple's Soul Dimension then began to materialized into my sword spirit form as I transferred a part of my consciousness towards the sword spirit that I have created in the Core Disciple's Soul Dimension.
