The special uses of the elixir, the secrets in the minds of senior brothers and elders, Hu Fei could clearly see through the entries. He hadn't been happy for too long, and that day he came to the Tibetan Scripture Pavilion. After reading the entry on the elder in front of me, I couldn't help but break into a cold sweat. [Zhao Xun, the elder of the medicine garden, had a short life expectancy due to an accident, but he was unwilling to die. [Five months ago, he came into contact with your fellow demon sect brother Cao Zixing, and under Cao Zixing's temptation, he fell into the devil's path.

[Zhao Xun relied on his outstanding talent to quickly practice this magic skill to a small degree, and the longevity crisis was gradually alleviated. [However, this magic technique has a drawback. It must be assisted by an elixir, and one of the main ingredients of this elixir is the monk's life essence. [He has his eyes on you. "Brother, I'm one of my own." Hu Fei wanted to explain, but found that he was treated as an outcast.
