God of War Who Guards the Nation: Starting with Mecha

First of all, China's coastline is 32,000 kilometers! It's 32 million meters! Not the 300,000 meters you mentioned! You have made our country more than 100 times smaller! Then you have to build a super alloy wall that is hundreds of meters high and tens of meters thick. I don't even say that giant humans and beasts can drill holes. The wall is useless unless you build it with the floor! Even if there is only a wall, even if the behemoth has a tough steel wall, let's calculate that the wall is 32 million meters long! Let's consider the height to be 300 meters (a few hundred meters plus 300 meters for the foundation is not enough), and the thickness to be 50 meters (a height of several hundred meters can block monsters, but a thickness less than 50 meters can't withstand it), that's 32 million X 300 X 50 = 480 million cubic meters! That's 480 billion cubic meters! Steel bars are 7.85 Tons/cubic meter. Even if the super alloy weighs the same as steel bars, 7.85 Times 480 billion = 3,768 billion tons! Most iron ores are at 50%-60%, which means about 7 trillion tons of ore are needed. What's more, there must be many rare minerals in super alloys. There are no such reserves in the world. Even if it is all iron ore, what is the concept of 7 trillion tons of iron ore? In 2020, the world's steel production will be less than 2 billion tons! This is a difference of thousands of times! Besides, there are only 221 days left! You have to mine, smelt, manufacture, and build! If you do this, the whole world will be waiting to die. There is no need to struggle. The monster is coming, and you have only built a few hundred kilometers! Directly destroyed by the group!

The plot can be just that you don't just describe your personal image. It's too naive. Let's describe each one one by one. It won't be tiring for you to write. Our heads will hurt just by looking at it.

There are still such orthodox little white articles now. I feel like I'm back in 2012.

There are many books about time travel and rebirth from the apocalypse, various preparations, and various system cheats, but this one is not about being reborn and preparing for the apocalypse at all. It's just a purely pretentious article, it has nothing to do with the apocalypse, and the pretentiousness made me almost sick with embarrassment. Come in and complain🥵🥵

This book is poisonous! ①: Chapter 13: The protagonist is able to recruit a school laboratory... And plagiarize his results... How awesome is this character??? Let's talk about it later

Update soon, it feels good.

The first part is written well, but the second part feels like it was written by another person. It's better not to write it at all if it doesn't connect the beginning and the end. I really can't read what's written on the back.

The plot is about 120 chapters long. After that Iron Man appeared, it was a bit confusing and I didn't understand it 😅

The Dragon Emperor God of War adds the rebirth and return, adds the heroine who commits suicide by jumping off the building, adds the system, and adds ancient dinosaurs. It is equal to a novel without talking about brains.

The book written by AI is pretty good. Surprisingly, I can still read the first few dozen chapters.
