The fifth year of Zhengyong, the first day of April.
Pseudo-Yan's Zheng Yuantao secretly assembled twenty thousand Dragon Cavalry to launch a sudden attack on the Imperial Capital!
On the same day, the Empress Dowager fell gravely ill, all Imperial Physicians gathered at Cining Palace.
Three days later!
Tiger Mountain Pass!
Located on the northeastern side of the Imperial Capital, this pass was the most formidable defensive pass in the world over three hundred years ago.
The city wall towers ten zhang high, surrounded by mountains named Tiger Mountain, with only a narrow path for people and horses to pass through.
Legend has it that during the founding war of Great Yu over three hundred years ago, Immortals fought four life-and-death battles here.
After this battle, the Tiger Mountain Pass landscape changed dramatically, the earth cracked, surrounding mountains collapsed, forming ravines and hills.
Yet, Tiger Mountain Pass in the center became a lone fortress.
