Prompt: masterpiece, best quality, 4k In the center of the picture, there is an arched stone bridge spanning the river. The bridge is solid and ancient, and the stone bricks have a rough texture. On the bridge, there was a traveler who looked down and out. He was wearing shabby clothes and carrying a heavy baggage. He led a thin old horse, its coat was dull and it had obviously experienced many hardships. Below the bridge is a wide river, with ripples on the water showing the rapidity of the water. The background of the picture is a dark sky. The sun is slowly setting in the west, and the sky is dyed with the afterglow of the sunset. On the left side of the bridge, an ancient tree twisted its branches, its branches wrapped with withered vines. Several black crows sat on the branches, and they made piercing cries, adding a desolate and mysterious atmosphere to the whole picture. On the far right side of the bridge is a dilapidated farmhouse with a simple and peaceful appearance. Smoke rose from the farmhouse kitchen chimney.
