In 1963, Wang Lei, a scout who had just returned from the border battlefield, stepped into the courtyard of Sijiu City, covered with smoke and medals. What greeted him was not the warmth of the neighbors, but the disgusting hostility: Yi Zhonghai was paving the way for Silly Pillar. His secret plot, Jia Zhang's behavior and seeking "compensation", and Xu Damao's clandestine frame-up tricks. What made him even more furious was that his family was forced to lose ground by these beasts because of the rumors that he "may be sacrificed". . When he couldn't bear it anymore, the "Iron-Blooded Guardian System" was suddenly activated, and it came with ten thousand square meters of storage space. Killing "animal points" can be exchanged for food, medicine, weapons and even rare technologies of the era. A cold light suddenly appeared in Wang Lei's eyes, and the bloody nature of the battlefield murder god was completely awakened: "If you dare to touch my family, all the beasts in the hospital will be spared!" He used the system as a blade and space as a shield, using the most decisive means to tear apart the mask of hypocrisy, beat the blood-sucker back to his original form, and send the schemer into despair. In the process, he accidentally crossed paths with Lin Lan, who had just been transferred to the sub-district office. The two went from testing each other to dealing with the turmoil in the compound side by side. Finally, in the filthy courtyard, they supported a pure land for their family and fought a counterattack against the tide of the times.
