All facilities were restored to their best condition. It was when Jing Xi inspected the results. Jing Xi flew around the city wall several times and returned to the district mayor's mansion.

Open the light screen on the table, and the map model of Nancheng District rose. A thin yellow grid line floated in the air at a height of 300 meters.

This is the air defense cordon in Nancheng District. Usually, only this layer of yellow line is opened. Once external objects invade, or people and objects inside touch this layer of yellow line, the air defense energy cannon will knock the opponent down.

If a special situation occurs, there will be an invasion of a strange beast, and a layer of red net cable will be opened at an altitude of 300 meters. The red line will not be like the yellow line, it will only have a warning effect and will not cause harm to people.

A red line is a very powerful laser line. Once an object touches a red line, it will be burned and sliced.

The first layer of grid red line is the lowest defense. Jing Xi clicked on the light screen and the second layer of grid red line lighted up at a high altitude.

Click the three-layer grid red line, four-layer, and five-layer until the top ten-layer grid red line opens. The ten-layer grid red line floats densely in the air. At this time, even a fly flies into pieces and burns them to ashes.

Seeing the bird accidentally flying into the grid red line in the light screen, it instantly turned into ash and evaporated. Jing Xi quickly turned off the red line. Although the red line is easy to use, it consumes a lot of energy and cannot be wasted like this.

With ten layers of grid red lines protection, as long as the beast tide is not very long, the city wall and red lines can be used to deal with it.

"This thing is easy to use. As long as the density of the network cable is increased, let alone flies, it can't even pass the air." Xue Wu looked at the red line being turned off reluctantly.

"Then you need enough energy." The grid red line is easy to use, but it consumes a lot of energy. It is not a special situation. Who would be willing to open a ten-layer grid red line?

When he saw that Nancheng District was fully equipped, the happiest thing was Zhongbian. He was most familiar with the situation in Nancheng District. Over the past few hundred years, Nancheng District's defense has reached its strongest.

Even in the Fourth District of South, Jing Xi asked him to build dozens of shelters. Those houses were nothing in the first, second and third districts in South Districts. As long as the houses built by the District Mayor's Mansion will meet that defensive standard.

However, the South Fourth District is indeed very precious. With those houses, the South Fourth District fell, and as long as people ran into the shelter, most of them could escape their lives.

Building a shelter in the South Fourth District can not only protect the people of the South Fourth District, but also avoid conflicts with the houses built by other districts and district mayors' offices.

After all, people in the South Fourth District do not pay rent and protection fees, so Jing Xi can only do this.

Jing Xi was finally satisfied with the defense of Nancheng District. The rent that he collected had been spent, and the number one priority was mentioned for the district mayor's mansion.

Fortunately, Jing Xi opened several stores early and purchased a lot of KC Orion specialties. In addition, when collecting rent, the merchants used materials to pay the rent, and finally set sail with a warship, transported the things to other places to deal with them, and exchanged some funds for turnover.

Jing Xi's behavior of repairing the city wall was laughed at by the public for several months, but finally everyone couldn't laugh.

Dongliu City ushered in the biggest beast tide this year. Outside the city wall, there were no traces of humans, and densely packed strange beasts were wandering outside the city.

An alien beast trying to climb up the city wall was burned to death by the red lines of defense covered on the wall.

Occasionally, there are a few riot hunting beasts in the city. Because the protective measures are in place, the mouth, claws, tails, etc. are all equipped with protective covers. Once something is found to be wrong with the hunting beast, it will be killed by the people or patrol team.

The first wave of beasts trying the waters was passed safely in Nancheng District.

A few days later, the air began to stir again, and the strange beasts that came outside the city became larger and larger, and half a wall-high strange beasts began to appear.

At this time, the third floor of the defense red line was opened in Nancheng District, and all the people from the city defense team were dispatched.

In the air-raid shelter on the city wall, the sound of cannons often sounded. All the people in the South Fourth District had run into the shelter and walked on the streets of the South Fourth District, deserted and thought they had approached the ghost town.

In the district mayor's mansion, Jing Xi looked at the light screen and showed dense black dots like the migration of ant colony, and was in a heavy mood.

If there are only a small number of low-level alien beasts, satellites cannot capture their information at all. Now they are indeed displayed in black, indicating that the situation is very serious.

Jing Xi asked the loyal blade beside him, "Does this happen often to KC Orion?"

"It's not often, such a large-scale beast tide happened more than ten years ago." Zhongbian replied.

Jing Xi raised his eyebrows, but fortunately it was not unprecedented, which means that Nancheng District can resist the past.

"How did the district mayor deal with this before?"

The phenomenon of the light screen display is really scary. Jing Xi was unsure and didn't know what to do, so he could only ask Zhongbian.

Zhong Ren replied expressionlessly: "When the former district mayor saw this phenomenon, he directly blocked the defense red line of the South Fourth District, and used all the energy to supply the defense red line above the South First District, and the defense red line of the houses built by the district heads of the second and third districts."

"What? The defense red lines of the South Fourth District have been withdrawn. Isn't that the people in the South Fourth District waiting to die?" Jing Xi couldn't believe it.

Xue Wu and Yin Chen used to know that Wild Stars were cruel, but they didn't expect that the population of a district would give up if they said they would give up. That would be the lives of hundreds of thousands of people, and it was difficult to accept it for a while.

Zhongren saw their incredible eyes and explained: "The houses in South Fourth District are not from the mayor's mansion, and they do not pay rent. When energy is insufficient, they will naturally give up on them."

"How long will the beast tide last in this situation?" Jing Xi's face turned gloomy, indicating that she was in a bad mood.

“About a month.”

"Can the energy of the District Mayor's Mansion support the defense red line that lasts for so long in one month?" The energy burned by the defense red line is calculated by area, minute by minute. Thinking of the huge number, if Qin Tianming is here, he would be scared to faint.

Everyone was calculating how much energy they spent in their hearts. Jing Xi was indeed grateful that fortunately, she sold a ship of supplies a month ago, otherwise she would have to take everyone to abandon the city and run away.

Now I am weighing the possibility of giving up the liberty of the South Fourth District, removing the defense red line above the South Fourth District, and strengthening the defense red line of the refuge.

Thinking of various possibilities, in doing so, only a small number of people in the South Fourth District who were hiding in the shelter could escape the disaster.

It is not that the house in the shelter is not strong enough, but that the main defense will become the third district of the South and fourth districts become the main battlefield. When the two sides exchange fire, it is very likely that the people in the shelter will be injured by accident.

Seeing Jing Xi not making a sound, Zhongren was afraid that the people from South Fourth District to entrust people from other districts to death, so he advised: "District Mayor, please broadcast the people in South Fourth District. The beast tide will continue for another month. In order to save energy loss, the defense red line over South Fourth District will be closed in 5 hours. People who do not prepare sufficient supplies will try to find a way to prepare enough food for five hours."

Yin Chen saw Jing Xi frowned and advised: "Miss, every time you encounter a big beast tide, everyone will give up on the South Fourth District. You just do what most district heads will do, and you don't have to be burdened. Besides, you have built a shelter for the people in South Fourth District. Compared to all deaths, you have protected some people, which is good."

Everyone was in a bad mood, but it was related to their own interests and joined the army of persuasion.
