The attack system of the entire Gu Immortal Great Array cannot be easily activated, once activated, it will continue to attack the enemy for three days and three nights, and then it will take another thirty years before the next wave of attacks can be launched. Because a huge amount of energy will be consumed in the process of attacking, with the concentration of the aura of the mortal world, it must be absorbed and replenished for thirty years before the energy can be refilled.

In order to make up for the shortcomings of this large array in terms of attack, there is a small attack formation in the four directions of the southeast, northwest, and northwest of the large array, and these small formations can be activated at any time and used repeatedly, and there will never be a situation of energy exhaustion.

As soon as Yun Feiyang knew that there were still four small attack formations in the four directions of the original Gu Immortal Great Array, he immediately followed the guidance of this book and first found a small hidden door embedded in countless runes on the round wall in the east of the Gu Immortal Great Array.

As soon as he found this hidden door, he immediately beckoned to his parents and the two elves, and they hurriedly and cautiously walked to Yun Feiyang's side.

Yun Feiyang pointed to the small door in front of him and said, "There is an attack formation hidden in this door, I want to go in and have a look." ”

Yun Haohan and Yu Xian said in unison: "If you want to go, let's go together." ”

Yun Feiyang said: "Okay, let's go to the danger together." He simply put the two elves in his breast pocket.

Yun Haohan and Yu Xianxian both looked at the two elves in surprise, and they both shrunk into small dots a few inches long at once, and actually got into the pocket of their son's chest, which really surprised and amused them.

Yu Xian Xian couldn't help but stretch out her slender jade hand and touched the pocket on her son's chest, she felt that this pocket was bulging, and the two elves were chattering inside, not knowing what to say.

She couldn't help but pat her son's head dotingly and said, "You little guy has a lot of flowers!"

Yun Feiyang had already followed the guidance of the golden book, and pressed his finger on one of the oblong runes, and the small door quietly slid to the side, revealing an oblong doorway.

Yun Feiyang was the first to enter this doorway, and he found that there was a staircase behind the doorway, so he walked up the staircase, and Yun Haohan and Yu Xianxian followed closely behind him.

After a hundred steps upward, the three of them entered a small circular hall, which was exactly the same shape as the huge hall below, and was also engraved with glittering runes.

The difference was that there was a round table in the center of the hall, and when the three of them walked to the table, they saw that there was also a book made of gold leaf on the table.

Yun Haohan and Yu Xianxian couldn't understand what was written on it at all, Yun Feiyang picked up the golden book, pointed to the runes on it and read: "Gu Immortal Great Array Eastern Attack Formation." ”

As soon as he opened the title page of this golden book, he saw that a huge circular light curtain immediately rose on the round table, and what appeared on this light curtain was the huge cave guarded by two out-of-body stage masters before he entered the secret realm. At this moment, in this huge cave, four out-of-body stage demon path masters appeared.

Yun Haohan and Yu Xianxian also saw this mirror image at the same time, and they were extremely surprised: "How can you see that huge cave far away at the entrance of the secret realm in this formation hall?"

Because this huge cave is really impressive to them. Eight years ago, when they entered the secret realm, there was a thrilling battle in that cave, but fortunately, there was only one Yuan Infant Master guarding there at that time, and the two of them finally escaped into the secret realm dangerously and dangerously.

But after that, the Demon Dao Sect of the Earth Moon Star strengthened its guards, and the two of them could no longer get out of the secret realm.

Yun Feiyang observed the movement in the cave, and told his parents in detail about the contents of the first golden book.

Yu Xian said: "Since this small attack formation can be used continuously without energy depletion, then why don't we try its attack power, can we kill those four guys in the cave in one fell swoop?"

Yun Haohan was more cautious and said: "After we are fully prepared to go out, we will launch another full-scale attack, and we will be caught off guard by the Blood Shadow Gate, so we can take advantage of the chaos to run out." If we launch an attack now, we are afraid that we will be startled, and the Blood Shadow Gate will definitely send more masters to guard it, which will cause a great disadvantage to us to rush out of the secret realm. ”

Yun Feiyang said: "Let's simply understand all the four small formations in the southeast, northwest and northwest, and then it's not too late to attack." ”

So, according to the guidance of the golden book, they boarded the attack formation in the south of the great array, and on the light curtain here, they saw the outermost entrance of the entire secret realm, as well as the entire large square. A whole thousand Demon Dao minions were killed by the meteor clone here before, and now there are actually more Yuan Infant Minions gathered.

Seeing the vastness of the clouds, the jade slender smacked his tongue: "I didn't expect that the vigilance of the Blood Shadow Gate against this Gu Immortal Secret Realm has been greatly improved, when we entered it back then, there were only two hundred low-level minions in the Bigu and Jindan stages, and now even the masters of the Yuan Infant Stage have become minions and are used to handle the entrance of the secret realm?"

Yun Feiyang said: "When I came in, I killed a thousand of these minions, and now it has doubled all of a sudden, it seems that the power of this Blood Shadow Gate is really not to be underestimated." ”

Next, the family of three probed the attack formations of the Gu Immortal Great Array in the west and north, and on the light curtain of the Western Palace, they saw the situation in this deep ditch at the bottom of the entire Ten Thousand Demon Mountain Range, and saw that on every section of the mountain road, there were demon path minions constantly patrolling and changing guards.

What surprised them the most was that on the central light curtain of the hall in the north, what they saw was actually a stronghold of the Blood Shadow Gate, where there were rows of houses with strange styles, inhabited by a large number of Blood Shadow Gate people, and a command center shrouded in the Demon Dao Formation.

According to the introduction of the golden book, Yun Feiyang pressed one of the buttons on the round table, and the internal situation of this command center was immediately displayed on the light curtain. In a room in this command center, they saw two out-of-body stage masters, arguing about something, only to see the two of them looking excited, making all kinds of strange gestures.

Yu Xian Xian couldn't help but say, "This Gu Immortal's attack formation is really ingenious! The situation in the command branch of the Blood Shadow Sect, which is not known how far away from us, can be seen clearly, it is really incredible, but it is a pity that I can't hear what they are arguing about." ”
