Upon hearing Xue Yunrou's words, Li Xuan could not help but hold his breath.
He had once repelled an imposter version of the Liao Empress 'Shulv Ping' and her tens of thousands of cavalry at the mausoleum of the Tai Grand Emperor of Liao.
But Li Xuan still dared not underestimate the mausoleum of the Tai Grand Emperor of Liao.
He knew that the real Empress of Liao had certainly attained the immensely powerful Rule of Extreme Heaven.
What they had encountered was just a fraction of the undead army roaming the outskirts of the mausoleum.
The real elite of the mausoleum of the Tai Grand Emperor of Liao were always within the mausoleum.
The Pishi Army concealed within the mausoleum, along with many accomplished generals and founding heroes of the Great Liao who were forced to be buried alongside Empress Shulv Ping, were very significant indeed.
