Tangyu once again applied acupuncture to Major General Feng using the Tai Yi Heart Sutra, and this time the session took a full hour. After finishing, Tangyu felt somewhat drained, breaking into a cold sweat. However, to his delight, he achieved some gains. His Pure Yang Power had made some progress, and he even faintly sensed the verge of a breakthrough to the Sixth Layer. This feeling, something Tangyu had long craved, had always eluded him, but just now he had caught a glimpse of it.
