The first one basically meets the conditions, and the last one is also an underground shelter, but it is a collective life. The two middle books are basically enjoyable articles.

Steel is the bone, flesh and blood is the shield - within the Great Wall is home! Seven years ago, his parents used their bodies to block the metal rain and pushed him into the air raid shelter. Seven years later, the disabled young man Lu Chuan inherited the inventory, awakened the sleeping good machine, and became the last master of all machines. Shi Feng put the dagger engraved with "Breaking Army" into his hand: "The job of the Iron Guard is not to make you a hero, but to protect the people you should protect before becoming a hero." Ye Ling blocked the fatal blow for him and smiled and said that he still owed half his life. When the names of a hundred thousand iron guards were engraved all over the city wall, when the hearts of 270 good machines were beating under the wall - the young man finally understood: behind him was his sister, his partner, and the last human home in this wasteland. Taking a step back is an abyss. Then just stand and hold on.

Reader note

It is consistent, the subject matter is novel, there are not too many clichés, the descriptions of small-scale battles are brilliant, and the descriptions of the destructive power of various modern weapons and equipment are also realistic. There is no sense of disobedience that rifle bullets cannot kill mobs. The plot has now reached the interstellar escape stage, and the coordinates are in the Proxima galaxy [smile]

Reader note

The first book has a system at the beginning, unlimited modifiers, no Madonna, but a female protagonist. It's quite interesting, but the writing is a bit redundant. Recommended star rating: ⭐⭐⭐⭐⭐ The second book is an explosive soldier, similar to Red Alert. I suggest to give the recommended star rating: ⭐⭐⭐⭐ The third book, I won't say much, just read it yourself, it only has 6.2 Points. Recommended star rating: ⭐⭐
