Not long after Zhang Fengxi returned, Xie Jianshen, true to his word, imprisoned him within the walls of Fuxi Palace by erecting a powerful spiritual barrier around it.
Upon discovering his boys' weakened condition, Zhang Fengxi took both of them to the mausoleum, the one place in the entire palace that harbored abundant spiritual energy, enough to stop the flow of time and preserve a heavenly body from decaying.
