The walls of Purple Moon City are about 200 zhang high, and the width at the top reaches 88 zhang, and the whole body is made of huge Akatsuki rocks, and this huge project can only be built by the strength of cultivators!

However, this huge city wall was not the most important in Purple Moon City's defense system, because if you really thought that you could rely on this city wall to stop the tide of millions of spirit beasts, it would be extremely naïve and naïve!

The true defense of Purple Moon City is composed of a large protective array, an underground protective array, and a protective formation inside the city wall.

The Great Array of Protectors can be regarded as the first line of defense on the ground of Purple Moon City, but its array eyes are all in Purple Moon City, and it is divided into eight places, that is, the formation center, in principle, if these eight formation centers are not destroyed, Purple Moon City will be safe and sound!

It's a pity that when building this Purple Moon City, only the countless ghoul beasts were taken into account, because those ghoul beasts would only attack stupidly, but now the ones attacking Purple Moon City are spirit beasts with very high intelligence, and these spirit beasts can not only attack from the ground, but also from the ground!

And this also caused the eight formation centers in Purple Moon City to have to operate beyond the limit, transferring a large amount of defensive power to the position of thousands of feet underground in Purple Moon City, because once those spirit beasts that were good at operating underground broke in in this way, the consequences were absolutely unimaginable!

Therefore, the protective array on the ground will become insufficient in defense, and every time it is violently attacked, it must be maintained, and during this period, the cultivators will need to fill it with countless human lives!

It is precisely because of this that the city wall, which originally had no use, was divided into lines.

At this moment, Feng Ruozheng was standing on the city wall, watching Lan Ling bargain with the commanders of the five adjacent demon hunting camps, none of them expected that "the seemingly simple matter of changing guards would become so tricky, because none of the several nearby demon hunting camps were willing to switch defensive positions with Luo Bi's demon hunting camp.

As a last resort, Lan Ling had no choice but to discuss with these five demon hunting camps at the same time, but although they finally agreed to change their guards, they demanded that Lan Ling's demon hunting camp must bear five zhang of defense space for each demon hunting camp, and this means that Lan Ling and they need to bear one hundred and twenty-five zhang of defense space!

Because everyone knows that when the tide of spirit beasts rushes up, even if it is a defensive space, it will encounter huge pressure, "This twenty-five zhang will definitely be a deadly defensive space!"

"Lan Ling! Promise them! It's only twenty-five zhang, we can still handle it!"

Feng Ruo's sudden words ended Lan Ling's bargaining with the five cultivators.

"Feng Ruo! this is not a joke!" Lan Ling turned her head to look at her with some puzzlement, although she knew that Feng Ruo's strength was very strong, but after all, she had not experienced the tide of spirit beast attacks, so she couldn't imagine what kind of terrifying situation it was, at that time, even if there was an extra zhang of defense space, it would probably cause more than a dozen companions to fall!

"Of course I'm not joking, promise them to change guards!" Feng Ruo ordered lightly, of course he knew the terrifying beast tide, but at the same time he also had absolute confidence in his own strength!

Lan Ling hesitated for a moment, and finally reached an agreement with the five demon hunting camps to change guards, but this agreement was difficult for everyone to understand, even Tang Qing, Peng Yue, Qu Yun and others were like this, because they worked hard "almost to fight with their lives, so that this demon hunting camp was kept in its current state, if it was due to this change, resulting in senseless sacrifices, no one could figure it out!"

Although they didn't say anything, Feng Ruo could clearly feel it, and the two combined demon hunting camps were guarding a distance of fifty zhang each, clearly protesting silently.

Feng Ruo didn't explain much about this scene, let alone communicate with Tang Qing and the others, because today's first bō spirit beast tide attack has begun!

According to past experience, this first bō attack will be launched one after another with the second bō attack, and even the third bō attack, with no long interval in between, and no exact attack time, but one thing is not wrong, that is, after the defensive power of the city protection array is weakened to a certain extent, the most jī fierce and palpitating third bō attack will also be launched!

As for the first and second bō attacks, everyone can basically act casually, and there is no problem even choosing to meditate in place. , but since Feng Ruo was here for the first time, he naturally refused to let go of this way of understanding the attack of the spirit beast tide!

At this time, with bursts of roaring and whistling, I saw a group of dark clouds rising in the sky in the distance, which was formed by thousands of flying spirit beasts, and below this dark cloud, there was a dense and countless tide of spirit beasts, under the trampling of such a number of spirit beasts, the whole earth trembled with a burst, and even the people on the city wall could clearly feel it, and this is still a distance of dozens of miles, you can imagine how shocking this spirit beast tide will be when it appears near!

But this sight did not cause even the slightest nervousness or fear to the many monks on the city walls, and they still did what they had to do, as if they were staying out of the matter and watching irrelevant things!

This situation is also a matter of course, after all, more than a month has passed since the emergence of this spirit beast tide, and you can see and experience this shock every day, naturally no one is afraid of this anymore, because the person who is afraid has already died for a long time!

"This first bō attack is all some weak spirit beasts, they are completely used to consume our combat power, if we spend mana to kill them, we will naturally lose the ability to attack in the next step, and if we don't kill them, it will cause huge damage to the city protection array, so under normal circumstances, this first bō attack is only attacked by thirty percent of people, and then alternately rotated, it is important to kill these spirit beasts to the maximum extent at the same time, but also to ensure that the third bō attack has the most peak state！”

At this time, Lan Ling explained to Feng Ruo and Lian Su in a low voice, and then, after hesitating for a long time, he said: "Feng Ruo, it's not that I don't believe you, it's just that you can never imagine how terrifying the attack we have to face when we lose the protection of the city protection array, so, I hope you can understand!"

"I said, I can handle it, in this way, Lian Su and I are responsible for the defense space of thirty-five zhang, and you are responsible for commanding the others to guard the ninety-zhang line, there should be no problem!" Feng Ruo suddenly turned his head, smiled at Lan Ling confidently and smiled, he is not too exaggerated, in fact, as long as the big piece of the silver armor is released, it is enough to protect the area of thirty zhang, and when the time comes, it will definitely be very easy for him and Lian Su to cooperate with each other!@.
