In the evening, after dinner and a bath,
Lin Zichen sat crossed-legged on the bed, attempting to use spiritual power to strike his acupoints.
Shen Qinghan also followed suit.
The method of striking was the same as when using Qi-Blood.
Only the Qi-Blood Power was replaced with spiritual power, which was condensed into needle-like forms, forcefully thrusting into the middle of the acupoints.
"Hiss! Hiss! Hiss..."
With each strike on an acupoint, Lin Zichen gasped from the pain.
However, the acupoint remained completely unresponsive, showing no signs of being penetrated by spiritual power at all.
After over half an hour of continuous attempts, he did not break through.
Lin Zichen gave up.
He thought that opening the acupoints probably didn't require spiritual power.
After all, he was cultivating the Blood Tempering Technique, and it might still rely on Qi-Blood Power to open the acupoints.
