In 1933, in the cold winter, Chen Mo woke up and faced the Great Wall. The Japanese invaders were invading. When the rivers and mountains were in danger, he stood up and tempered and proved himself in the flames of war. Facing the steel armor of the Japanese army, in order to reduce China's casualties, he developed technology, from physical assault to rocket launchers, from broadswords and spears to over-the-horizon fire strikes. When we become stronger, of course we will fight back in the same way. Chen Mo will come to see you with a powerful army!
