In ancient times, the sea was divided into three seas, the land was divided into four deserts, and the state was divided into five continents. People who became immortals in ancient times believed that the sea was an indispensable spirit for the survival of all living beings, and the four deserts were the place where immortals lived. Mortals lived on the five continents. Therefore, on the day of enlightenment, they all bathed in the sea and were reborn, and the blood was replaced with gold. From then on, people with golden blood were worshiped as immortals in the world. A drop of blood can change the soul to be reborn. Although bathing in the sea is dangerous, there are many pursuers. Later, one sea dried up, and the two seas gave birth to spirits, fearing the way of heaven, and merged into one sea, which was frozen for thousands of years. As a result, the world was in chaos, with few believers and demons running rampant. Even the sea is reborn, giving birth to wisdom again, and is called the North Sea. However, those who have achieved Taoism have been able to strengthen themselves and exchange their golden blood. However, the world still feels the grace of the North Sea. Those who pray for blessings from all five continents call Beihai, and gold is also the color of those who have achieved Taoism.
