Time flew by, and in the blink of an eye, forty years had passed.
The Birthless Killing Sword unexpectedly reached Combined Body Perfection, twenty years ahead of schedule.
After some thought, Jia Ren understood the reason behind this.
The higher the quality of the Demon-Sealing Spirit Tower, the better the enhancement effect. Strengthening one's self with the Demon-Sealing Spirit Tower should start from the Nascent Soul Early Stage and increase gradually, with the highest efficiency at Combined Body Perfection.
The Birthless Killing Sword used the Sacrificial Fire of the Demon-Sealing Spirit Tower at its peak. This was different from the Demon-Sealing Spirit Tower that increased efficiency gradually.
Eighty years were reduced to sixty, which was indeed good news.
Sixty years had passed, and his cultivation progress in the Mid-stage of Lianxu Stage had reached eighty percent.
