The setting sun dipped below the horizon, leaving a smear of twilight red as blood across the sky.
At this moment, Gu Chen transformed into a dazzling beam of light, streaking across the heavens like a meteor, rushing to Tiandu at the greatest speed.
"Halt, who goes there!"
By the time he arrived in front of the gates of Tiandu, Gu Chen was surprised to find that the usually crowded city, with its endless stream of people entering and exiting, was now completely deserted.
Furthermore, the gates of Tiandu were tightly shut, with rows of the Royal Sword Guard stationed on the city walls, each with a stern expression.
When the radiance dissipated and they could clearly see Gu Chen, they were utterly astonished.
"The... the Marquis of Wu'an?!" A soldier exclaimed. The commanding officer regarded Gu Chen with a wary eye and then, beckoning someone over, he spoke in a low voice.
