Everyone was surprised, and they all looked at the front of the big tent, and they saw Xuanwu who suddenly appeared there at this moment, his face was pale and obviously weak, as if he had just had a serious illness.

Huan Yin, who was sitting in the first seat, had already stood up when he looked at Xuanwu and said, "Old guy, are you better?"

Huan Yin had been worried about Xuanwu for a long time before, after all, the scene that Xuanwu suddenly appeared when he was deducing the light curtain was too terrifying, as if he had fallen into an evil spirit. Huan Yin was afraid that Xuanwu would be hit by some evil and vicious moves, and the most important thing was that they had shown Xuanwu before, but they couldn't find the reason and couldn't find a solution. You must know that Xuanwu is one of Huan Yin's closest people, and Huan Yin doesn't want to lose him so inexplicably. What's more, this is still at the time of the big war.

Xuanwu coughed twice, then slowly stepped into the tent, and after bowing to Huan Yin, he said: "Don't worry, the old man has rested for a while, and he is already much better, and there is no big problem." ”

Hearing this, Huan Yin finally relieved his heart, so he immediately said: "Old guy, what do you see on that light curtain?"

Huan Yin's question was also the most curious question for everyone, so everyone's eyes were still focused on Xuanwu's body. Who knew that Xuanwu shook his head and said, "I don't remember." The old man used the deduction method before, and he should have seen something. However, it turned out to be like a nightmare, and the old man must have been frightened when he was in the dream. But after waking up from the dream, the old man couldn't remember anything, so he only retained the feeling of fear. ”

For a moment, everyone looked at each other. In most people's eyes, the Xuanwu Protector is good at deduction, and he is a master of arcane techniques in his own right, and he can do things that ordinary monks can't. Who knew that the light curtain was so evil, not only did it make Xuanwu fall into the way, but he couldn't understand it at all, was it too weird?

Xuanwu continued: "Your Majesty, the old man always feels that something big is about to happen, and it is best to advance our advance speed. Otherwise, I'm afraid of unexpected changes. ”

Huan Yin nodded and said, "Just now you said that you have found the flaw in the light curtain?"

Xuanwu said: "Yes, although I don't know what that light curtain is, although I have the Tao of that thing, but the old man is not a vegetarian. In the moments before he lost consciousness, the old man had at least found the source of the light curtain. After deduction, the old man found that the light curtain did rely on the formation to exist. The formation is huge, and the arrangement is extremely complicated. However, the core key is the four formation eyes located in the four corners of the eight heavens in the north, southeast, and northwest. As long as these four array eyes can be found and destroyed, the light curtain will be self-defeating!"

Now the light curtain is the biggest obstacle for Huan Yin and them to enter the north for eight days, if they can really make it self-defeating, it is of course the best. It's just that everyone couldn't help but be surprised when they heard Xuanwu's words. Because Xuanwu said that the formation that supported the light curtain had four formation eyes.

You must know that the Heavenly Realm's research on formations is second to none in the Three Realms. There are too many formation masters in the Heavenly Realm, and there are quite a few of them in Huan Yin's account now. No matter how complicated the formation is, no one has ever heard of having four formations at the same time.

The formation eye is the core of the formation, and the more complex the formation, the more formation eyes there are. The most complicated formation they had heard of was the Three Formation Eyes, which had been handed down from ancient times, unbelievable and powerful. As for the four eye formations, everyone didn't even think about it.

"Does my Heavenly Realm really have a formation with four formation eyes?" Finally, Hu Zi couldn't help but whisper.

Yue Fengyun said: "For thousands of years, the three formation eyes have been considered the limit of the formation, could it be said that this formation is not the formation of the heavenly realm?"

As soon as these words came out, everyone looked at Jiang in the camp. Jiang shook his head and said, "Hell doesn't even have the formation of three formations. As for the human world, I'm afraid there is none. ”

"Okay!" Huan Yin was in a high position, and opened his mouth to suppress everyone's topic, and then continued: "This array is powerful, and Xu is one of Rahu's hole cards." He has always been good at some special doorways, and it is unknown whether he has found some kind of ancient array. Judging from the strength of this array, it is not surprising that it has four array eyes. ”

"Anyway, now that Xuanwu has already touched the direction of this array, we have to find a way to break it. No matter how many formations it has, once it is broken, we will be in the north for eight days!"

Everyone came back to their senses, and Dai Tianyao thought for a while and said: "Lord Xuanwu, according to what you said, if you want to break the formation, you have to sneak into the formation, but the formation is so strong that it is difficult to break through at all, how can we send someone to break it?"

Xuanwu said: "There is a weak point in the south corner of the light curtain, which has also been seen through by the old man, as long as we try to break through that weak point, and then send people in, this matter can be successful." The old man has also thought about how to send people in, and he needs to trouble the imperial concubine to take action personally. ”

Donghuang Yu'er said: "What does Lord Xuanwu mean that I will specially build a passage and send people in?"

Xuanwu nodded: "Specially built passages, which can allow people to break through more smoothly, after they enter, it is difficult to be detected, and they can sneak into the city unconsciously and carry out actions." ”

Donghuang Yu'er nodded: "This matter will be handed over to me." ”

Huan Yin stood up again and said, "In this case, this matter will be led by the Shadow Lord." Speaking of this, Shadow Jue had already stood up, and Huan Yin continued to say when he looked at him: "Shadow Jue, you brought a small army into the city this time, and after entering the city, spread rumors, shake the hearts of the soldiers and people in the city, and took the opportunity to find out the enemy's situation and send a message back." You bring another group of mage masters into the city to help you destroy the four formations. As soon as the light curtain disappears, I will lead the men to kill. When the time comes, don't be in a hurry to come out, continue to hide in the city, take advantage of the chaos to destroy the local teleportation formation, and cut off their support!"

Shadow Lord shouted, "Yes!"

Huan Yin looked around at everyone and said, "Others, lead the army forward and camp fifty miles, prepare for battle with all your might, and prepare to charge!"

"Yes!" the crowd shouted in unison, and their confidence grew. According to Huan Yin's thinking, this battle is only afraid that it will be nine out of ten!

Soon, everyone was up and running according to the plan.

First of all, Xuanwu and Donghuang Yu'er teamed up to secretly send a total of eighteen people led by Shadow Jue into the northern eight heavens, so that they could officially start the operation they were responsible for. Then, under the leadership of Huan Yin, the large army moved forward again and stationed only fifty miles away from the Eight Heavens Moat in the north. Here, if you are at an extremely high place, you can already faintly see the huge island at the foot of the northern Hachiten.

So, as time went by, some changes gradually occurred within the eight-day huge battle circle in the north.

The most obvious change is naturally Huan Yin's side. After Huan Yin advanced to fifty miles, it was naturally not just as simple as stationing. In addition to still practicing day and night, Huan Yin had already dispersed the entire army of millions of people and arranged it, completely surrounding the entire moat and the huge island from the north, east, south, and west for eight days.

North of the northern eight days is the waterfall and the end of the sky, so under the encirclement of Huan Yin like this, the northern eight days can be said to be impermeable, once Huan Yin launches an attack, unless the strength in the northern eight days city is extremely strong, otherwise, they will be at a disadvantage because they are surrounded, and it is difficult for anyone to escape for their lives.

Of course, with such a change, the defenders in the Northern Eight Heavens City did not know the situation at all. For some reason, they seemed to be extremely focused on dispatching troops, and Huan had been here for many days and didn't even notice that they had sent a spy out.

In the eight days in the north, the changes are not obvious, but like spring rain moisturizing things, quietly and really.

As the information about the Eight Heavens City in the north was transmitted to Huan Yin by the Shadow Lord through a special way, Huan Yin knew that the progress on the Shadow Lord's side was still going well. Not only was he constantly familiar with the enemy's situation, but he had also found the four formations of the light curtain, and the formation masters who were traveling with him were studying ways to break the formation.

Although the formation behind the light curtain is incredible, the eye of the formation is the lifeblood of the formation after all. And to destroy the formation, it is much easier than to form. In addition, the formation master's formation attainments sent out by Huan Yin are not trivial, and Huan Yin believes that it is only a matter of time before the formation is broken.

Of course, the causes of these changes can only be known through the information provided by Shadow Jue. But there is another change, Huan Yin sends people to investigate outside the light curtain every day, and gradually, you can see it directly-

During the eight days in the north, the troops stationed in an orderly manner gradually began to become a little chaotic for some reason, as if there was a panic spreading in the eight days in the north, which made people feel uneasy.
