Zhang Tianhe had been studying with the old Taoist priests for more than ten years but had not mastered the mental skills. He ran to the ancestor's memorial tablet and cursed, and a thunder struck him into the mountains. When I got up, I noticed a feeling of Qi coming out of my Dantian. I had started practicing the Taixuan Sutra. My skin turned white and I looked like I was seventeen or eighteen. After waiting for a long time to dry clothes by the stream, a shout came from the distance: Senior brother! Master said that you have gone through the tribulation and asked me to come find you! He looked back and saw a young man in monk's robes running over, panting. Zhang Tianhe opened his mouth to ask where this was, but the young man had already rushed towards him and hugged his arm: Master, you have really mastered the thunder technique! This mountain is called Longhu Mountain. Damn it, I was struck by lightning and returned to my ancestor's hometown.
