The developer of vickers machine guns.

Ma Keqin was born in Sangersville, Maine, USA on February 5, 1980. When he was a child, his family was poor and he couldn't afford to read. /kloc-at the age of 0/4, he became an apprentice to a carriage manufacturer. He doesn't have much cultural accomplishment, but he is born with an inventive mind. He goes to his uncle's factory to study his invention every day. Because of many inventions in electrical appliances, Ma Keqin was constantly pushed out by Edison Company, the electrical appliance boss in the United States at that time, and had to leave the United States to open up a new electrical appliance market in London and settle there. At that time, the European continent was at war, and the sensitive Ma Keqin soon realized that making weapons was an excellent opportunity to make money, so he changed his research direction and devoted himself to the field of rapid-fire weapons. Ma Keqin had no professional background, so many experts looked down on him at that time. 1883, when he started the experiment of machine gun principle, no one still believed that he had finished the invention. But in 1884, Ma Keqin really succeeded in manufacturing the world's first automatic repeating heavy machine gun powered by gunpowder gas, with a firing rate of 600 rounds per minute. In the Battle of the Somme in World War I, the Germans used Maxim heavy machine guns to shoot at the British troops in dense formation, and nearly 60,000 British troops were killed in one day. Death made people really realize the great power of this automatic heavy machine gun. Ma Keqin obtained a patent for this.
