On June 25th, while alien civilizations were attacking the interstellar Great Wall, a group of silicon-based life forms disguised as meteorites broke through the defenses and descended upon Earth. Thus began the ground war in earnest! At the same time, humanity truly saw the aliens they were fighting!

It was a silicon-based life form with insect-like behavior. Upon discovery, humans immediately surrounded and eradicated it. They also named it: Beta.

Beta has an extremely strong body and vitality, and also has super high combat ability.

Although they do not have respiratory and digestive organs, some betas will devour inorganic and organic matter. Any human they find, whether dead or alive, will be chewed up.

However, they do this not for energy. More likely, it is to make humans, these carbon-based creatures, feel the fear and pain of being chewed by them! It is as if they are born with a certain hatred factor in them...

In addition, beta also has the characteristics of nesting and special intelligence transmission. Each nest has the function of independently launching operations and a command system.

Beta is more of a biological weapon than a living being. This is a conclusion drawn from Beta's unique appearance, its extremely high combat capabilities, and its proactive and disorderly destructive actions.

Judging from the observation data so far, the basic principle of their behavior is to invade the ground in groups or burrow underground, and they rarely act alone.

The overwhelming power of betas comes mainly from their unimaginable reproduction speed, resulting in endless numbers.

Often, their massive collective charge would shatter humanity's proud defenses, ultimately leading to the fall of countless areas and heavy civilian casualties!

But as our understanding of it deepened, humans gradually gained a foothold and formed a certain degree of effective defense.

However, the valuable experience and understanding gained came at the cost of the sacrifice of countless soldiers.

"Meiling! The teacher has issued the assembly order. Our mecha team has a mission."

Hearing the shouts behind her, Wang Meiling wiped away her tears, regained her resolute face, turned around and replied, "Okay, I'll be right there."
