Urban defense is divided into two parts: one is the front line outside the city, and the other is the eye of the formation inside the city.

The front line outside the city is bounded by the main city wall. The magic array with the extension of the city is a maze array overall.

When the magic circle is activated, all external channels of each affiliated town will be closed. That is to say, as long as the formation is not broken, the monsters entering the formation can only follow the only road left for them and go straight to the main city, and then they will be blocked from the city wall by the team formed by the city.

This is the best experience that monks have gained in fighting monsters for millions of years.

In most cases, this driving tactic is very effective. However, when monsters go to the main city, they will always accidentally attack the inside of the maze, so it is important to maintain the key nodes of the town's extension magic array. Otherwise, the damage in a small corner may also turn into water of a collapsed dike.

This is why Yan Kaiting immediately took back the workshop when he was centrifuged at the "Tiangong Kaiwu" branch in Dongtun Town. The branch is one of the key nodes of the town and it is necessary to ensure that there is no human threat.

People's hearts are sometimes deviled when they are profitable. Among the rumors in various states, there are many "smart people" who want to use the hands of monsters to eliminate dissidents, which leads to tragedy in the entire city.

Another major danger to the front line outside the city is the beast tide.

"Time of Demons" is the most fragile moment when the world's barriers are most vulnerable. Monsters outside the world will try every means to use this opportunity to find gaps to invade. If the sentient beings in Jianmu have a Taoist seed, then monsters outside the world will mean death.

Taoist seeds and monsters cannot coexist. Once they meet, they will be neither born nor dead.

In such a twisted space, the entanglement and strangulation of the large-scale life and death aura will greatly stimulate the ferocious beasts on the nearby wasteland. Therefore, those ferocious beasts that usually desire blood food will gather, riot, and come in the breath.

However, the ferocious beasts in the violent state will experience a decrease. Although most of them will be pulled by the aura of the magic array to attack the main city, a small number will ignore the formation and rush directly into the town, so the cultivators can only be solved by the organization of each town.

Therefore, the front line outside the city is usually the place with the most intense battle situation and the most stressful. The custom of Yujing City is that all members of the Public Jue Alliance will issue strong men and teams in proportion to the four gates.

In recent years, the leaders of Tu, Yan, Fu and Lu families have basically been fixed, and they will send their own strongest players.

All large magic arrays have array eyes, and the array eyes are as big as a city and surrounding towns.

In the 1,700-year history of Yujing City, at least half of the buildings and streets have been demolished.

However, no matter how the changes are, the entire city has always consciously expanded and rebuilt radially around with the Four Symbols and Four Seasons Garden where the array eye is located. Therefore, until today, the array eye of the city magic array is still the most central location in Yujing.

The "Four Symbols and Four Seasons Garden" is round on the outside and square on the inside. The four seats represent the sun, Taiyin, Shaoyang and Shaoyin's flower surfaces are separated by four corners. Spring mulberry, summer hemp, autumn rim, and holly are planted under it to describe the four seasons.

The maintenance costs of this garden are derived from the city taxes. Except for the four square courtyards made of Huabiao that cannot be entered, the four seasons of woods are usually open to the whole city. Because of its elegant landscape, it attracts many literati and monks to talk about Taoism in Qing Dynasty, which is quite a bit of an elegant gathering place.

Of course, Yan Kaiting didn't come much in such a place.

Today, the entire "Four Elephants and Four Seasons" park, along with the surrounding neighborhoods, is extremely quiet, and no one can see a figure. Ordinary urban residents will not come here at this time, and the teams of each family have not yet reached the meeting time.

According to convention, the front line outside the city needs to be in place first, and after the inspection is not bad, then the inner city's array eye part is integrated, and finally the self-defense teams in each block are turned to.

Yan Kaiting circled around the four Huabiaos and silently looked at the surrounding environment. When he was about to turn the second round, he heard the sound of clothes rubbing from not far away, but he could hardly hear footsteps.

When Yan Kaiting looked up and saw the visitor, he knew that the other party was deliberately making a sound to remind him that someone was coming.

This person with a thorough manner is actually Han Fenglai.

Han Fenglai held the guzheng in his arms and stood in the wind. His white robe was slightly lit with blue light. He wore a soft mask that looked like a skin but not a skin, and the shimmering light on the robe covered most of the faces on his lips.

When Yan Kaiting saw that it was him, he couldn't help but frown. Han Fenglai's name was not on the list of assisting defense issued by the City Lord's Mansion. However, the news of his coming to Yujing was not completely confidential. Wearing a mask only means to cover up the excitement.

Han Fenglai greeted, "Master Yan."

He saw that Yan Kaiting did not respond immediately, and explained: "The war is about to begin now. If I formally submit a famous post to the City Lord's Mansion, it may be even more inconvenient for everyone. However, since the monster has encountered it, I have to do my best."

Yan Kaiting was stunned by the court. What he thought was a bit in vain.

Han Fenglai is not an ordinary person. "Yetian Workshop" is listed together with the monk sects, and is one of the seven sects of the four sects and seven sects. In terms of identity and status, the young master of the Han family is much heavier than the master of the Yan family.

If he spread his identity and formally visited Yujing City, the families in the city would have to make up for a series of formal etiquettes. Moreover, the risks of the city increased greatly. If such a person had an accident in the city, who could bear the responsibility when facing the "Yetian Workshop" to raise an army to punish him? If he came here in vain, he could still defend an uninformed person.

I have to say that Han Fenglai showed a very good temperament, considerate, calm and generous. Although he seemed shy and introverted, he would ignore this issue after saying a few words.

Sometimes Han Fenglai responded slowly during the conversation, but it was not because of hesitation, but because his language seemed to be a little slow. But this small flaw had no effect. When he expressed his point of view in full, he would find that he was extremely decisive.

Yan Kaiting bowed and said, "Young Master Han is thoughtful."

Han Fenglai said, "Call me Xiao Shao, it's more convenient."

Yan Kaiting glanced at him, and there seemed to be nothing to say except to respond.

Next, the two of them stood face to face, stopping talking, as if they could not find the topic for a while.

After a moment of silence, Han Fenglai said, "This 'Four Symbols and Four Seasons Garden' is really good. When I look at the Yujing Formation, I use the 'Star Four Seasons Method'. The advantage is that the array eye is constant, but the rest can be adjusted partially according to the changes in the building, without all the need to be pushed down and rearranged. It is very suitable for use in a large city with a population size like Yujing. The garden is added here to the array eye, and the vitality of the trees in the four seasons is used to weaken the death energy of the monsters. Although it is not beneficial in wartime, it is of great benefit to clean up after the war."

Yan Kaiting looked up at the closest Huabiao and said, "Oh."

It seemed that he felt that his reaction was too cold, and he remedyed: "I rarely come here and don't know much."

A "puchi" laughter came into the ears of the two of them. At some point Fu Mingxuan turned out from the other end of the road.

Although the two sides were more than ten feet apart, the two did not deliberately lower their voices when they spoke. Fu Mingxuan's ears could hear clearly.

Fu Mingxuan raised his footsteps, his figure flashed, and he stood beside Yan Kaiting in the blink of an eye, patted his shoulder, and before he could say anything, he just laughed "hahaha".

Han Fenglai, who was standing opposite, was not only red in his ears, but could be seen under his mask, and the blush fell into his neck. Earlier, Yan might have thought he was embarrassed, but now the most in line with the facts is likely to be that he is trying to hold back his laughter.

"Dalang, your unique skill that you always chat to death has finally not only activated it at me." Fu Mingxuan said: "No wonder you can't chase a woman."

Yan Kaiting was angry and embarrassed, "No! There is a confidante on the entire Xianying Bridge!"

At this time, lively voices came from the road when Fu Mingxuan came, with several strong men leading the way, and teams of monks came. Some were wearing uniform warrior uniforms, while others wore badges to separate.
