With only more than five hundred years of True Qi, Wei Fan didn't continue opening acupoints. Merely increasing True Qi without corresponding martial techniques was naturally ineffective.
Otherwise, even if all acupoints were opened, the change in strength would be minimal.
...
In the evening, Wei Fan came to the Merit Hall. Just as he reached the door, a voice sounded in his ear.
"You've come!"
Wei Fan's pupils contracted.
Although within the Demon Suppression Bureau, he was not highly guarded, he wouldn't fail to notice if someone approached him closely.
He turned back to see an old man, hunched over, who had somehow appeared three feet away, squinting at him.
Wei Fan clasped his hands and said, "You are Elder Huo?"
Elder Huo nodded lightly and strolled to the side of the Merit Hall: "If you want to learn the Soul-Slaying Demon-slaying Saber, follow me!"
