Tang Dynasty Sword Shadow

When the prime minister was stabbed through the heart by a sword, the murderer turned out to be a farmer who was about to starve to death. General Yu Wenyao of the Qianniu Guard was ordered to investigate the case and chased him all the way down the blood trail - to Yizhou, Qiuci, and the Tubo camp. He also tracked down the evil sword "Dog God" that can suck human blood, and also tracked down the shadow in the darkest place of the Tang Dynasty. But he didn't expect that the last knife would hit one of his own.
