In 1849, a gold mine was discovered in California in the United States. At one time, the gold rush was set off. Adventurers from the west and east gathered here to fight for an inch of mine. After a full 8 years of fire and bloodshed, groups of people exchanged for their blood and sweat. The gold is ready to go home and end this brutal and dangerous day. A large group of gold rushers took their servants and took their wives and children and wandered for thousands of miles to begin another journey of fear. They took a boat trip from San Francisco to Panama, crossed the Isthmus of Panama, and finally sailed to New York. After this group of people left Panama two days later, on September 10, 1857, the steamboat “China America†was met with an unexpected disaster. The small steamboat had more than 750 people and the draft was too tight. A hurricane hit and a storm hit the cabin and the sea water leaked in. It was found that the sails were blown off by strong winds and the fire of the boiler was extinguished. The endless sea made the people desperate. They formed a self-rescue team, women and children were sent to the lifeboat and all were rescued, but 423 Taojinhan was buried along with the incalculable gold. The survivors have been unable to determine the exact location of the shipwreck. The whereabouts of these California gold treasures have become a mystery. A well-known treasure huntist named Spencer, who had found achievements in sinking several ships in the American Civil War, expressed strong interest in the ship, the Sino-American Steamboat, which carries gold. At present, he It has taken 15 years to find the "China-US," and is convinced that it has found the exact location of the ship's sinking and hopes to salvage the gold within two years. Spencer seems to bring a glimmer of light to the mystery of unlocking the California treasure.
