Dragon Tiger Mountain!
It was where Chinese Taoism originated from, and it was named one of the four sacred mountains of Taoism!
It was said that the patriarch of Dragon Tiger Mountain, Zhang Daoling, who founded the sect, had refined the Nine-day Divine Pill on Yunjin Mountain. It took three years to be completed. There was a dragon-tiger phenomenon in the sky the day when the medicinal pill was refined. Zhang Daoling had ascended into the sky after consuming the medicinal pill, so the descendants then changed the name of Yunjin Mountain to Dragon Tiger Mountain.
Meanwhile, Zhang Daoling became a Celestial Master.
The Dragon Tiger Mountain had been passed down since the end of the Han dynasty. It had been 2,000 years. The sect leaders had always been someone with the family name Zhang. The Dragon Tiger Mountain remained standing tall even after Maoshan and Laoshan came in.
One could determine its status in the spell world judging by that.
