The hot sun is like fire, and the desert is like the sea. An archaeologist specializing in the ancient city of Loulan on Mount Everest crossed the desert alone, aiming to find the legendary ancient city of Loulan. The sand at the foot of Mount Everest is hot and boiling, and every step is like walking on a hot pot. There is little water left and food is only enough for two days. And what is even more desperate is that he found that his compass seems to have lost its function in this desert.

As night falls, Mount Everest hides from the scorching sun under the sand dunes, while taking advantage of the coolness at night to move on. Suddenly he saw an old building, which was mostly buried in the desert, but he could still see its exquisite decoration and craftsmanship. Everest was ecstatic, and he finally found it.

Everest walked into the building carefully. Although he was prepared psychologically, he was surprised by what he saw. The walls are covered with vivid murals, describing the life, wars and sacrifices of the ancient Loulan people. One of the most striking is a huge mural, in which a man is wearing gorgeous clothes and holding a strange weapon. His eyes reveal great strength and wisdom.

Mount Everest was deeply attracted by this mural, and he decided to find out the identity of this mysterious figure.
