Memoirs of the Life of Armed Police. I recommend this book to you.😋This was a military-military career novel. The main character was called Yunnan. At first, he was a young man who hated his family and the city he was born in. With an inexplicable passion, he joined the army in Yunnan, thousands of miles away. After experiencing a passionate military life, he gradually became a qualified national guard. At the same time, a mysterious plan that should not have been used on them had unknowingly begun. In the face of the endless stream of drug dealers and other dark evils, he held the steel gun in his hand tightly and crushed the evil hands that constantly emerged from the darkness with a group of strong guards of the Republic.
