United District 13: Gunsmoke Again

In the year 4099 AD, two scientists from the Segre II galaxy traveled to the Milky Way, where they discovered a beautiful and brilliant planet - the Earth. During a hundred years of observation, the two scientists excitedly conveyed their experiences to the home star S2-A. Unexpectedly, this brought disaster to the earth. In AD 4247, the rulers of S2-A united with other planets in the Segre galaxy and launched a war against the earth. Soon, the entire earth was in devastation. In order to make up for their mistakes, the two scientists dropped tens of thousands of cosmic gene chips on the earth, forcing some humans to evolve and gain the ability to resist alien creatures. After a long war, the rulers of the Earth decided to transfer part of their sovereignty to the Segre galaxy, establish a coalition government, and coexist peacefully with the Segre people. After that, the earth used "Genesis" for several years and was divided into thirteen areas at the same time, known as the "United Thirteen Areas" in history. Seeing the success of the Segre Galaxy, other planets began to get ready to take action. Wars often broke out between the planets, and the universe ushered in the most unstable period. In order to resist foreign enemies, the coalition government organized a group of genetic mutants as soldiers to rush to the front line. Shen Jiu is one of the super soldiers. Once the son of a wealthy family, he encountered sudden changes when he was thirteen years old: his father, who controlled half of the economic lifeline of District 13, was missing, and his uncle defected and joined the rebel army to become bigger and stronger. All he was left with was his idle brother. In order to survive in troubled times, he had to become a warrior and rush to the front line.
