The night in Ilha Verde City was originally more charming. In clear weather, there will be two bright moons hanging in the sky at night, and the illuminated earth is covered with a silver veil, which is extremely beautiful and moving.

However, the appearance of demon clouds made the day and night almost dim and pitch black here, destroying its beauty.

Not only that, but in this darkness, danger looms all around, and no one can predict when they will recede.

Outside the east gate, the flames of one or two zhang high stretched for thousands of miles, burning fiercely, and it had been two days. In the past two days, the demon beasts buried in the fire have been roughly estimated to reach tens of billions, causing heavy casualties to the demon beast tide. However, the demon beasts have been adjusting their offensive formations, and the number of demon beasts like moths fighting fire has been greatly reduced.

Now, in front of the human camp, the wall of fire is still there, but gradually, no demon beasts can cross it anymore. Obviously, the monster tide has basically been adjusted in place.

Zhang Weidong and Liu Chun parted unhappily, and when they returned to the second array, Zhao Lin was not there, and it was estimated that they had gone on patrol. He didn't go to practice for the time being, and he went around and went to Cao Ping and Ning Xiuxiu.

At this moment, everyone in front of the formation was extremely nervous, and so were the monks here.

Seeing that Zhang Weidong was coming, Cao Ping breathed a sigh of relief, was very happy, and welcomed him over.

There is a small circle here, including Cao Ping and Ning Xiuxiu, a total of four foundation building monks, two men and two women. However, the cultivation of the other two is not high, and they are only one layer of foundation.

Zhang Weidong didn't know what the names of the two of them were, and they hadn't dealt with each other, so he glanced at them slightly.

"I've seen Senior Brother Zhang!" the two of them were very enthusiastic, and they hurriedly got up to greet them, a little respectful.

In this team led by Zhao Lin. Many people have witnessed Zhang Weidong's strength or heard about his deeds. Don't dare to underestimate it anymore.

"Senior Brother Zhang, these two are Senior Brother Ding Xue and Senior Sister Dong Jue!" Cao Ping introduced.

Zhang Weidong nodded: "Senior Brother Ding, Senior Sister Dong!"

There's no time to be polite here. After Zhang Weidong said hello, he asked about the fortifications.

Cao Ping gave a brief introduction and expressed his worries.

There was a raging wall of flames in front of the formation, which could block the pace of the demon beast tide, which greatly reduced the defensive pressure on the human monks. However, the most dangerous time begins. The last two days will be the craziest time for the demon beasts. Because the demon beasts also know that once the demon clouds disperse, their most favorable conditions will be gone. You have to hold on to a blow,

At that time, there may be monsters sneaking underground, and there are more likely to be a large number of aerial monsters sneaking up overhead. The latter, on the other hand, will be the focus of attention.

"Don't worry too much about the ground, as long as the monks who know the 'Stone Setting Technique' continue to cast spells, they can greatly strengthen the ground, even if the demon beasts that are good at shallow sneaking are difficult to break through, but. This would hold back at least a third of the monks, so that there would not be enough manpower to defend against an attack from the air. The people in our second array don't have time to rest, so they have to go up!"

The Stone Setting Technique is not complicated, it is an earth and stone vitality technique. Qi cultivators can master it. However, the deeper the cultivation, the larger the area covered by the cast. The stronger nature is. The only caveat is that any Genki technique has a temporal nature. The same goes for stone concrete, once the force is dissipated, the ground will recover, so it needs to be constantly reinforced.

In this way, just the defense against the underground dragged a large number of monks, which indirectly increased the difficulty of defending against the demon beasts in the air.

Zhang Weidong has seen the situation of groups of demon beasts in the air, which can be described as 'covering the sky and covering the sun', and they are fast and extremely flexible, which is difficult to defend.

Once they attack, the human monks can only be beaten, and the defensive camp can easily be broken through. Just imagine, if countless aerial demon beasts swoop down like hail with a desperate blow, and then attack with talent, it only takes a few seconds, and it will be chaotic here.

This is also where Cao Ping and others are worried, and they are very helpless.

Although, a large number of Qi cultivation cultivators under his command have already changed, all of them are advanced Qi cultivation cultivators, and their strength has increased a lot compared to the original. At the same time, the people of the first array, retreated to the second array, and changed their positions. But the pressure on them, the foundation building monks, has not been alleviated at all.

The wall of flames was in front of it, and it was not easy for the demon beast to pass through. And all the attacks may be changed to underground or airborne, and they, the monks of the second array, are also the targets of the attacks, and they are treated equally.

"What about Qingzhou City?" asked Zhang Weidong.

"In the city, we don't need to worry about that!" Cao Ping said after a pause. "Every city is equipped with a large city protection array, once it is activated, it can cover almost the entire city, those demon beasts can't be broken in a short period of time, even the demon king!"

"The Great Protective Array, and this defense?" Zhang Weidong's eyes lit up and he was surprised. "With this big array, wouldn't it be safe and worry-free?"

The strength of the formation, he admires. For example, a set of 'Upside-Down Five Elements Array' in his hand, once it is arranged, it will take several hours for the real people in the middle stage of Jindan to break through, and the real people in the early stage of Jindan will not be broken.

If there is such a big array, it can be attacked, and it can be defended, at least it will be invincible.

"Senior Brother Zhang, how can it be so easy!" Cao Ping shook his head and smiled bitterly. "If this city protection array is just guarding the inner city, it is estimated that it will be no problem for a long time, but it will not work to cover the city of thousands of miles, it needs too much vitality, it is too huge, every breath is overdrawing a large amount of vitality in the Yuanjing vein, it can't support much time, if it is opened for too long, the huge Yuanjing vein under this Qingzhou will be exhausted, and then Qingzhou will really perish!"

"The problem now is that we don't need to worry about the city, but outside the city, especially our defense here is not a way, we have to destroy the demon beasts in the air, otherwise we are in greater danger, and you know the most about the demon beast Chao Zhang, I don't know what suggestions Lu Dao has?"

As soon as Cao Ping explained, Zhang Weidong's old face turned red and he laughed at himself in his heart.

He only knew that the Dao Formation was powerful, but he knew very little about it. Indeed, the operation of the formation must have enough energy to do so, and it cannot be interrupted at any time. Once the energy supply is interrupted, the formation will naturally not be able to function.

Like a large array to protect the city, covering such a large area of the formation. The amount of vitality required cannot be estimated, and ordinary places cannot be opened at all.

This is just a small episode.

Cao Ping and the others are still concerned about how to fight back against the demon beasts in the air.

This question. The others looked at Zhang Weidong with hope in their eyes.

To the monster tide. If it weren't for this encounter, it is estimated that many people would not have heard of it, and naturally, they knew very little about it, and even completely ignorant of it.

In this regard, Zhang Weidong is much more dazzling.

And Zhang Weidong couldn't refuse this request, so he groaned and said, "Let me think about it!"

"Good. I'm sorry to trouble Senior Brother Zhang!"

Cao Ping's eyes lit up, and they immediately waited patiently.

If Zhang Weidong can put forward even one suggestion, it is estimated that he can help everyone and reduce the number of deaths.

Of course, this thinking is an excuse.

Zhang Weidong was secretly consulting Zhang Fu in the Spirit Mansion.

In terms of understanding of demon beasts, he thinks that he can't compare with Zhang Fu.

"Is there something wrong with the young master?"

"Fu Bo, how should the demon beasts in the air guard and fight back?"

"Young Master is worried about the attack of the demon beast in the air in front of him?"

"Yes, if you don't want to. It is estimated that the first wave of attacks will not be able to hold out, let alone two days!"

"There are many ways, but, young master. I'm afraid that Qingzhou doesn't have these conditions-"

"So you can't help it?"

"Young master, if you completely repel it, it is estimated that there is no way. But reduce the casualties of human monks, or increase the casualties of monsters. Delay for a while, it can still be done!"

"Oh, what's the solution, I'm using it urgently!"

"It's just a little trick—"

"Whatever the trick is. As long as it works, many people are blind now!"

"Young master, don't worry, the Qi cultivators outside are probably prepared with bows and arrows, right?"

"Yes, everyone has a strong bow in their hands, and now it is the main means of attack against the demon beasts in the air!"

"And then?"

"What, then?"

"What the old slave means is that you can think of a way to increase the lethality on the arrow—"

"Arrows, toxins?"

"Cough, young master, the toxins don't have much effect, there are many air monsters in the desert who are not afraid of toxins, because they usually eat some demon beasts on the ground, such as red scorpions, etc., so they have a strong ability to resist poison!"

"Fu Bo, don't sell it, just say what to do!"

"There is a way to transform a batch of simple 'Burst Arrows', such as the juice filled with 'Sea Soul Liquid', 'Sand Vitex Grass', and 'Rootless Water', once it enters the demon beast group, it bursts open-"

"Ha Luha, Fu Bo, you really can do it!" Zhang Weidong understood the huge effect of this 'bursting arrow' as soon as he heard it, and he was immediately overjoyed.

"Young Master, you can find these contents in the first study-"

"Ahem, I'll have time to look at it later—"

found a simple and most feasible way, Zhang Weidong came back to his senses and said to a few people: "There is indeed a way!"

Cao Ping and the others were immediately overjoyed.

As soon as Zhang Weidong said, they did not hesitate to do so, and instructed the Qi cultivators under their command to collectively transform the 'Bursting Arrow', and there were still many of those medicinal liquids, which just came in handy.

Then, this little trick spread to Zhao Lin's ears, then to Chongjiang Crane, and most recently, to the entire defense line in the southeast and northwest.

Speaking of which, this little trick is actually not new. But the magic is that with the new applications of 'Sea Soul Liquid', 'Sand Vitex Grass' and 'Rootless Water', this effect is extraordinary.

And the simple transformation of the burst arrow is not difficult, and everyone can complete it quickly.

After about an hour, everyone's preparations were almost coming to an end.

At this moment, a huge sound of wind and thunder came from all around the sky, from weak to strong, humming endlessly.

"The monsters in the air are coming!

Bang!

Another loud bang!

This sound came from behind the human monks' front, earth-shattering, and with a single breath, the surrounding vitality was instantly absorbed.

This made everyone almost stunned, and many people didn't know what had happened to the road.

"The Great Protector Array is on!"

PS: The passive defense plot will soon come to an end, and it is relatively simple, because the initial stage is the most difficult, and the individual performance is not easy to reflect, so it took a lot of pen and ink to pave the way. Tiandao estimates that the plot will soon be the time to show their skills, and it will also be the time when the excitement will come, and the strength of the protagonist will be greatly improved. (To be continued.) )
