"The loophole?" The three of them turned their eyes and immediately understood. Lian Ting smiled and said, "Xiaodao, you mean, the blind spot of the big array?"

The blind spot of the big formation is a special term in the formation. According to Wang Jin's words, it is an academic name in the formation.

The blind spots of the big array are generally divided into two categories, but in general they are one category. To put it plainly, it means "ignoring" the word.

The formation method has always been a rigorous, comprehensive, and thorough representation. Any difference in the slightest amount will have different reactions.

A small one cannot form an array, and a large one destroys people.

Therefore, every formation method must be exceptionally rigorous when it is deployed, and there must be no mistakes. This is also the reason why there are so few array masters.

But there is one exception, and that is the blind spot of the big array.

The formation, especially the formation located in a certain area, is the most prone to blind spots, but the formation is not affected at all and can still be used normally. The reason is that it is not the formation that has a problem, but the formation. People have blind spots.

This type of regional formation, if you want to cover an area, you must divide all the areas into the formation and set it up in the formation so that the formation can take these places into consideration.

But if the people who set up the formation ignore a certain place in this area, the formation can still be formed and has its own functions, but there will be loopholes. Others can easily enter and exit from this loophole. This is the so-called The blind spot of the big array.

And the two types of blind spots happened to have been encountered by the kingly way, and the first one appeared in his Taoist Sect.

At the beginning, Su Man and Wang Mengxue, after King Dao upgraded their mountain guard formation, they could still go in and out freely through the teleportation formation, and it did not cause a reaction from the mountain guard formation, because when King Dao upgraded the formation formation, they did not consider it. In the past, the cheap old man still left a back door at his home, so a loophole appeared.

This is called an acquired blind spot. It is a blind spot left by someone deliberately. It can also be said to be a blind spot of the magic circle. When setting up the circle, no other magic circle exists, and only the outside is guarded, not the inside.

The second is the situation of Xu Saiguo, which is called congenital blind spot, or geographical blind spot. This kind of situation is relatively common. After all, a country's territory is likely to have something that cannot be taken into account, such as this type of being stolen. Others didn't know the path that was opened up, and then they didn't pay attention when building the formation, which caused the formation to be inherently incomplete and a blind spot appeared.

No matter which one of these two are, they are very deadly, enough to turn a powerful formation into a ridiculous flower.

"Well, it should be a blind spot. You have heard it just now. It is very likely a blind spot, so the secret passage should allow us to enter Xu Sai country safely." Wang Dao smiled.

Wan Xiaoyun still didn't quite understand, and asked, "Brother, why do we use a secret channel to enter? In fact, it's the same if we fly directly over, even if it is a Heavenly Protector of the Nation, Yun'er has a way to easily pass. Don't let anyone notice, Yun'er can do it. Brother, you should also be very relaxed, right?"

Everyone of the Taoist Sect can be called countless means, not to mention the martial arts and martial arts, that is, there are endless and amazing weapons on the body, which are enough to deal with any situation.

Wang Dao has never been stingy since his BUFF years have been completely free. He has acquired countless weapons for his disciples, armed them to the teeth, and can deal with any situation they are not good at.

Even Ting and Wang Lian nodded their heads, and they didn't understand why Wang Dao had to care about the secret passage.

Wang Dao smiled and said, "Of course we have a way to pass easily, but don't forget what Chang Ying said just now? Doesn't you find the origin of the secret passage a bit interesting?"

The three of them thought about it. They were all smart people, and immediately thought of a possibility. Wang Lian quickly asked, "Master, what do you mean, the other end of the secret passage is the royal hinterland?"

Wang Dao snapped his fingers and praised "Smart!"

Chang Ying said just now that her grandmother and a few brothers had fun to explore there. They were able to do such boring things after a little bit of strength. It can be seen that they are not very old, and they are all secondary and second-year teenagers.

In addition, as I said later, those concubines went to the front when they grew up, and it was a long time since the opening of the road. It can be seen that these children were about ten years old at that time.

According to the customs of the Shifang Continent, no matter which country it is, princes and princes before the age of fourteen are not allowed to leave the royal inner court privately. It is like practicing cultivation, let alone going outside.

Besides, I drove a mountain and hasn't been discovered by anyone. If it is outside, how can it be done? It has alarmed the people a long time ago.

After the mountain is opened, no one knows, it can only be the hinterland of the huge royal inner courtyard, a place dedicated to princes and princes.

What's more, when the National Defense Front was built, no one discovered this secret passage, which even more clarified this point.

The royal family is not accessible to anyone. Those formation mages, at most, are observing the approximate area of ​​the royal inner court. It is absolutely impossible to investigate in detail as a whole, otherwise the secret passage would have long been insecure.

These are sufficient proof that the location of the secret passage is not only in the royal inner court, but also a training ground that has been unoccupied all the year round.

"But if it's the royal inner court, why didn't Patriarch Chang just say?" Lian Ting asked suspiciously

Wang Dao shrugged and said, "I've heard Long Huang say about this. Generally, the training grounds of the royal inner courtyard are set up in some safe deep mountains and old forests. Although they are adjacent to the hinterland of the palace, they are not strictly a palace. It's mostly a royal possession, not even the back garden."

"In fact, people can go to that kind of place if they want, but most of them will not go because of respect or awe."

"Chang Ying's grandmother probably didn't bother to mention it, or coaxed Chang Ying with a story-telling attitude. There is no need to mention it in such detail."

"As for those people who went to investigate later did not mention this, it is probably because the place is deserted, but it is relatively close to the imperial city, and they didn't care too much. Anyway, it is not in the imperial city, there are still pathways to go around. Past."

"Long Huang also said that the princes who used to be his princes secretly ran out of the imperial city while they were practicing."

The three of them didn't disagree, and thought it was reasonable, especially Wan Xiaoyun agreed. She has been to many imperial cities, so she naturally knows this.

"What does the master plan to investigate? Why do you want to go inside the imperial city? You want to directly behead Lord Xu Sai?" Wang Lian asked curiously.

Wang Dao shook his head, and said, "That's not true. If we want to beheaded, we can also fly over freely. Anyway, no one can stop it. I just think Xu Saiguo is a bit strange. I always feel that there may not be that way. Simple, just in case, it is safer to enter from the blind spot of the big formation. If there is no problem, I also plan to sneak into the imperial city to see what happened to the king Xu Sai. His behavior is too strange. !"
