Qin Wen said with some curiosity at this time: "Then how should this array be used, how can we sense the defensive range of the formation, and whether it is under attack?"

The old man hesitated for a moment, pointed to a depression on the stone with his finger and said: "Your Excellency can put your palm on this, and the setting of the entire formation will appear in your divine consciousness, but the purity of the bloodline will represent the scope of your control, and the Heavenly Demon Lord's net back then can check the situation of half of the Northern City." ”

As soon as the old man said this, Qin Wen saw that Yun Fengyan was constantly giving the old man a look, Qin Wen was stunned for a moment, but immediately understood that these demon cultivators in Beicheng had not forgotten to introduce this magic circle to themselves, but because there was also the requirement that the bloodline control range.

If they brought it up, they would be a little suspicious of testing the authenticity of their bloodline, so in order to avoid leaving a bad impression in their hearts, everyone deliberately pretended to be confused, but Qin Wen knew that the drop of blood on his body was pure demon god blood, so he gently pressed his palm on the depression.

A powerful aura fluctuation poured into Qin Wen's divine consciousness, but this fluctuation did not bring harm to Qin Wen, but a lot of graphic images, these graphic images were only fragments at the beginning, but after half a pillar of incense, they gradually integrated into a complete picture, this picture is like Qin Wen is in it.

The first thing that appeared in front of Qin Wen was a net-like image, these images were like the lattice formed on the ground just now, and they were so large that Qin Wen could barely see what the picture was in the image, so he looked at it carefully and unnaturally, and as soon as his mind moved, these pictures suddenly shrank to a normal size with his divine sense.

The picture is the whole picture of the entire expulsion city, and every move of everyone in the city is clearly seen by Qin Wen. Except for some places that vaguely seemed to be blocked by spiritual energy, basically the city was completely under his own surveillance, and Qin Wen knew that these blocking places should be the high-level monk's own vitality defense, in case they were peeped at by other monks.

Qin Wen knew that the function of this magic circle was far more than that, so he took back his divine sense, and then asked the old man, "I can basically see the entire city of the entire Expulsion City now. I just don't know how to do this defense, do I still need a hedron to operate?"

"The whole city?" Several old men suddenly showed a look of horror on their faces, when the Heavenly Demon Lord left, he had said that the limit of this magic circle was to protect the entire Expulsion City, it seemed that the bloodline on Qin Wen's body was indeed a god undoubtedly, and the bloodline in his body should be the closest to the demon god.

The old man who explained just now said more cautiously: "The operation of this formation is also very simple, you only need to put the spar on this stone, and the adults can adjust the size of the entire magic circle according to their divine sense, as small as such a courtyard." If it were for what the Lord just said, the big one would envelop the entire Expulsion City. ”

Qin Wen thought about it, then took out a spar from his storage bag, and then put it on top of the stone, watching the spar gradually integrate into the stone, he asked: "The original Heavenly Demon Lord can spread his divine sense to half of the Northern City, did he set the defensive formation to the maximum limit value at that time?"

The old man shook his head slightly and said, "The speed at which this formation consumes spars is also relatively fast, generally speaking. Without a strong attack, a hedron can last for about a month. It can resist the attacks of the monks of the Holy Spirit Realm for half an hour, so usually the Heavenly Demon Lord just opens the defense to envelop the entire Heavenly Demon Garden. ”

After the spar was integrated into the stone, Qin Wen probed his divine sense into the array again, and felt that the scenery inside was clearer, and there was a fishnet-like aura shield faintly outside, Qin Wen knew that this shield should be formed by the defensive formation. He used his divine sense to gently unfold the shield.

The bigger and bigger it became, in the picture of the divine consciousness, the fishing net had been unfolded to envelop the entire expulsion city, looking at the bowl-shaped fishing net in the divine consciousness upside down on the top of the expulsion city, Qin Wen slowly breathed a sigh of relief, and suddenly the fishing net was touched. Qin Wen suddenly heard a few surprised inhalations outside, and he withdrew his divine sense from the array.

Seeing that the eyes of everyone in the room were staring at the sky outside, Qin Wen also followed their eyes, only to see a net-like aura shield faintly appearing in the sky, exactly the same as the one in his divine consciousness just now, and then the entire shield kept flashing, as if someone was attacking.

Yun Fengyan walked out of the room at this time, his body flew up slightly, and when he reached five or six zhang, he stopped, looked into the distance, and after coming down, he said in surprise: "My lord, you have now shrouded the entire expulsion city in the magic circle, and these attacks were detected only when the monks by the city gate suddenly couldn't enter. ”

Qin Wen didn't expect that his unintentional move would completely seal off the entire Expulsion City, but after feeling the fluctuation of the aura, several powerful divine senses in the city instantly glanced at the magic circle that suddenly appeared, and the few elders behind Qin Wen did not show weakness to exude their powerful divine senses, which were used to warn these monks not to let them act rashly.

Qin Wen only then understood the use of the defensive array, and then slowly withdrew the shield with his divine sense, and the four gates of the Expulsion City could enter and exit normally, Qin Wen opened his mouth and asked the old man: "What if the monk wants to enter and exit after the formation is opened?"

After listening to Yun Fengyan's words, the old man knew that what Qin Wen said just now was not an exaggeration to be able to view the entire Expulsion City, so he muttered for a while: "This is also relatively simple, just like the magic circle completely envelops the expulsion city, and the adults can leave the way in and out at the gates of the four cities, so that all the monks can enter and exit the magic circle through the city gates." ”

Lu Mo couldn't help but ask with questions at this time, "Then what if the enemies outside also sneak in through the city gate?"

The old man said with a faint smile on his face: "Lord Heavenly Demon also thought of this problem when refining the magic circle, in fact, within the magic circle, now the adult has mastered the control, all the monks in it, as long as the realm does not exceed the level of the magic circle, that is to say, the realm is under the heavenly demon, and those who cannot break the formation are already under the control of the adult, and the adult can control their life and death at will." ”

"And there is also a small mobile formation in the magic circle, which can move with the adults, and the adults can withdraw it at any time, and they can also make protection at any time, just like when cultivating, as long as this formation is shrouded outside the room where the adult is, then no one can sneak into this room, and when he attacks this formation, the adult will also be aware at any time. ”

Qin Wen nodded slightly, looked at the array of stones in front of him and said: "The scope of the expulsion city is too large, and it is useless to cover the entire city, I think it is most appropriate to protect the entire northern city, so that the northern city is not afraid of a sudden attack by the monks outside, what do you think? Where is it more appropriate to leave the four city gates?"

Several old men and Yun Fengyan couldn't help but glance at each other, with surprise on their faces, but there was also a hint of hesitation, Yun Fengyan said cautiously at this time: " My lord, although this method is good, it is also beneficial to the monks of our Beicheng, but there is one point, when the Heavenly Demon Lord's divine sense could cover half of Beicheng, he did not easily activate the formation, because the spar consumption used in the array disk is too large, if the family in Beicheng raises it together, there will be no drawbacks in a short time, and after a long time, the number of spiritual objects purchased will decrease, and the strength will be much weaker than the other two cities. ”

Qin Wen waved his hand and said: "This doesn't matter, the spar doesn't need to be raised by you, it only costs one spar per month as a maintenance cost, I can still take out this spar, there is a spar vein I found in the mountains and forests, and the spar in it is used here, basically it can't be used up for hundreds of thousands of years." ”

"Even now, we are a little far away from the mountains and forests of Nancheng, and the three deacons in Dongcheng already know the location of the spar vein, although I have added more manpower to the protection of the ore vein, I am still a little worried that they will do it blatantly. ”

When several old men heard that Qin Wen could give them the protection of their family's magic circle defense without them raising a little spar, they immediately respected Qin Wen, a monk in the Xuan Master realm, and Yun Fengyan opened his mouth at this time and promised: "Don't worry about this matter, the three little guys in Dongcheng have already warned them that day, and our entire Beicheng will protect the adult's mineral vein, and now it is estimated that the three of them don't even dare to move." ”

The old man who explained the magic circle to Qin Wen also spoke: "If your lordship is still not at ease, our family can send a few more spirit level monks to patrol the vicinity, and if there is a situation, we will come back immediately to report it, and even if Dongcheng and Xicheng join forces at that time, we can ensure that we do not lose a spare." ”

Qin Wen hadn't spoken at this time, and Lu Mo said with a grim face: "Danshi, isn't this magic circle able to envelop the entire Expulsion City?" And the attacks you use within the magic circle can't even be resisted by the Holy Spirit Cultivator, so it's better for you to use the magic circle to kill all three of them first, so that it will be done once and for all." ”

Qin Wen waved his hand and said: "Although I can kill them with the magic circle now, but things can't be done too much, they and I actually don't have much grudges, and I still have some contacts with Ji Chang, if you do it, it's a little inappropriate, as long as they don't fight the idea of spar deposits in the future, this matter will be settled."
