From MC's Perspective:
Time passed.
After reaching the limit, I switched methods. Then I started running the blood element method. I was so immersed in the practice that I forgot about the outside noise.
When I reached the limit by practicing the blood element method, I switched the practice again. This time it's the ancient healing method.
The ancient healing method would give powers once I completely mastered it. I doubted how long it would take me to do that.
I was totally immersed in the practice. After a long time, I focused on the three methods again. I should make it a daily habit to practice all three methods compulsorily.
Only then can I reach the Peak Stage of the General Rank.
When it was evening, I reached the limit by practicing the ancient healing method as well. My veins and meridians were under stress.
I needed to take proper rest before continuing the practice.
