In a secret corner of the underground palace, they discovered a new energy similar to electricity. This energy is called "blue aurora". This energy needs to be immersed in a specific pattern on a person's arm before it can be used. This energy can communicate with weapons and murals. People of a certain bloodline also become powerful due to this energy. Therefore, in ancient times, continuous wars started because of this energy. Until one day a man named Ji Hu appeared. He was the most talented person. At the peak of his martial arts, he also reached the peak of using the energy of Blue Aurora. He won the final war by force. However, he was tired of the war, so he destroyed all the "Blue Aurora" by sacrificing himself. Back in time, the protagonists are trapped in a cave. It happened that a foreign expedition team came to this cave to search for the energy source of this "blue aurora". At first, the foreigners were very friendly, and they actually discovered the remaining blue aurora behind a hidden earth gate. Then they accidentally discovered that the foreigners were hiding a shocking conspiracy. The protagonist and his friends immediately decided not to let the foreign expedition team leave here with the blue aurora, and began a life-and-death struggle with the foreign expedition team. In the end, the protagonists walked out of the cave, but they also paid a heavy price for it.
