In the home planet, the alert value of the general city can be divided into three levels, namely the red level 1 alert, the green level 2 alert, and the blue tripolar alert. Red alerts generally represent the lowest alert values, while blue alerts represent the highest alert values. As the alert value of the city increases, the corresponding danger also increases. Of course, these cities generally refer to large cities like Tenryu City. Because only a super city like this is qualified to have such a complete vigilance mechanism, and only when its political culture has developed to a certain extent, the existence of such a vigilance mechanism is meaningful.

Legend has it that in the primeval period, the home planet was not divided into five realms as it is now, but was bounded by territory, divided into hundreds of small regions, which existed in the form of a state called a state. Between countries, there is both struggle and cooperation. For the sake of its own interests, one country can wantonly harm the interests of other countries, and even do not hesitate to provoke wars and invade other countries. Now it seems that these actions are quite naïve, because the earth itself is a whole, and no matter how human beings fight, it is the home planet of their own existence that will be harmed in the end.

Although ancient humans have created many splendid technologies, even many of the techniques of that time cannot be restored to this day. But that doesn't mean they're smart enough. At least in terms of damage to the home planet, their "credit" is also the greatest, and it may be because of this that the most cowardly has led to the arrival of the Great Yan Era. In terms of human nature alone, although it cannot be said that human beings today are much more noble than in ancient times. But at least now they know how to protect the earth, the home planet where we live together. Today, there is not a single chemical plant on the home planet, and all the polluting industries have moved to other planets. Advanced technology can only be found in outer space. The earth has returned to its primitiveness, but this is not the backwardness of human beings, on the contrary, the times are advancing, and human technology is also changing with each passing day. This can be seen from the improvement of the combat power of servers and mecha in recent years.

Only a healthy home planet can give birth to endless human beings. Therefore, human beings have also understood a very simple truth, protecting the home planet is to protect human beings themselves. A businessman who returned from a trip to other planes once lamented: Only when you leave your hometown can you realize the importance of your home planet.

Floating clouds and wandering children (a poem expressing homesickness in the primeval period). The home planet is an eternal dream in the hearts of interstellar travelers. Because it is located in the center of a large galaxy, the cosmic environment where the parent star is located is relatively stable. At least not yet, I haven't heard of any race in the universe that has invaded the home planet Earth. Therefore, the alert level of the city in the home planet is generally rarely released. Those super cities are not only the political and cultural centers of the home planet, but also the political and cultural centers of the entire large galaxy and even the entire total galaxy plane. Therefore, these big cities all have some super strong people sitting in charge. Those who are idle do not dare to act recklessly. In the last millennia, the alert level has only appeared twice, and both times have been the lowest red alert.

So far, there has not been a single time in the history of the Great Yan Period, where there has not been a single highest blue alert. As soon as the blue alert is issued, it is really time for humanity to be wiped out. The only green alert in history is still in the year 2043 of the Great Yan Era, which is known as the end of divine punishment, and the only god suit powerhouse in the history of the Yan Era was born this year, this year the beast king Hetis led the biochemical beast tide to attack the holy city - St. Petersburg, this year St. Petersburg issued the only "green alert" in human history, and it has also become the highest level of issued warning value in human history. However, I believe that no earthlings hope to be broken by this kind of record.

The main force of defense is also different depending on the alert value. The lowest red alert, with the main defensive force being the clothier, supplemented by all the city guards, and special forces selected from the army. Sometimes, a small number of server troops will also be used as backups. Such a defensive mechanism constitutes a solid red cordon line.

Of course, if this line of defense is breached, then the entire city, that is, the entire home planet, as well as the entire large galaxy, and even the entire total galaxy plane, will automatically enter the second line of alert defense, green alert.

The Green Alert is mainly based on the subserver troops, and the other units are all auxiliary to it. Super strong people will also be dispatched at this time, whether the enemy is fighting alone or in a group, Green Alert is fearless. ,

However, fearlessness does not mean invincibility, if this second line of defense is also breached, then the entire total galaxy will enter the highest blue alert, and human civilization is at the most critical moment of life and death. Therefore, this is the most powerful defense line of human beings. Suits, mechs, and even heavy mechs banned on their home planet may participate in the battle. And some of the old monsters who have escaped from the world, and the ancestors of the major families should also take action. Of course, these are the best case scenarios, after all, human civilization has never reached such a dangerous state.

In extraordinary times, it is natural to use extraordinary measures. However, most of the time, the earth is in a relatively safe and normal state. In a normal state, the defense of the super city is also very loose. At least on the surface. When Ye Yu first entered Tianlong City, he didn't even encounter a city guard who guarded the door. The degree of freedom of the city can be seen.

Under normal circumstances, the security management of the city is the responsibility of the city guard, which is generally composed of military police, and the military police are uniformly dispatched by the city guard department established in the city. However, the military and police are generally only responsible for security, and ordinary criminal cases are handled by the Government Administration Department. However, a huge city, not only is it so simple as security, all kinds of government agencies, coordinated with each other, to create the current prosperous, but well-organized Tianlong City.

Among these complex departments, there is a department called the Urban Management Bureau, which is responsible for the order management of the city. The level is not high, but the power is not small, and it is almost one of the most popular departments in the city.

The self-employed freedmen had to rely on their snort if they wanted to do business in peace. Originally, they were all small businesses, and it was already very good to be able to eat together. However, some scum in some urban management bureaus use their power and make things difficult for them every time. It is not uncommon to be fined at the slightest and punched and kicked at the worst. That's why the self-employed freedmen call them "thieves" behind their backs. Wearing the uniforms of the official family (the uniforms of the chengguan are somewhat similar to the uniforms of the military and police in the city), but doing these things like thieves, it is really a shame, most of them have no power and power, they are just ordinary members of the nearly 100 billion free people in the big galaxy, how can they have the energy and financial resources to compete with them.

What's even more odious is that these dogs bully the soft and fear the hard, and they curry favor with the dignitaries and nobles, and for those hawkers whose status is not as good as their own, they treat them as shit and insult them arbitrarily. That's how the old couple was treated.

He actually called himself Rolling Ye Yu smiled, and said lightly: "What if I don't leave?" ”

"Hey, I really met a stupid *, don't be embarrassed to give your face, the little white face is quite handsome, aren't you good? It's cheaper for you this time."

"Okay" A strong man with yellow teeth was rubbing his hands, his eyes wandering around Ye Yu's body.

Xiao Mo couldn't help but be frightened, although he knew that Ye Yu was very capable of fighting, but this time the other party was a full five people, and each of them was carrying a mace in their hands, which looked fierce and abnormal, could Ye Yu handle it? Unconsciously, she, who has always hated violence, faintly hoped that Ye Yu could break out in the small universe and beat those five miscellaneous pieces.

"I'm going to use violence again, if I don't like it, I'll go farther-" Ye Yu glanced at Xiao Moss and said angrily.
