On the other hand, Huang Tiedan, although he was careless on the surface, he had already thought about everything clearly in his heart.

Huang Tie Dan had already analyzed everything, and knew that this mechanism was the key to the second palace at the moment, but this mechanism could be dangerous, and he needed to think of a magic way to open the mechanism without being killed by it. Huang Tie Dan frowned, and immediately thought of a good way, that is, to use the nerve arch to break the crystal ball, and then you can open the mechanism, without worrying about being injured by the mechanism.

After Huang Tiedan thought of this good plan, he didn't do it immediately, but pretended to play with everyone, and then shot a white feather arrow with his nerve bow to break the crystal ball.

From the time the white feather arrow was shot to the time everyone understood the magic method of the yellow iron egg, it was less than a second. In the next second, everyone didn't have time to complain a few words, or scold Huang Tiedan a few words, "The big-headed ugly monster is really slippery", etc., and there have been new changes on the field. Due to the new changes, everyone did not have time to deal with the yellow iron eggs, but began to be tired of dealing with the dangers brought by the new changes.

After the yellow iron egg shot an arrow, the white feather arrow hit the crystal ball at once. The crystal ball was as fragile as white tofu, and when it was hit by a white feather arrow, it shattered immediately.

In fact, this crystal ball is indeed as Huang Tie Dan guessed, it is a special mechanism to open the second palace. However, Huang Tiedan's knowledge is shallow, and he doesn't know much about dungeons and formations, so he doesn't know the true function of this crystal ball.

Copies, mostly opened by the great monks of antiquity. In the dungeon, there are abundant products and treasures, and there are treasures that are not found in the ordinary world, and in order to protect these treasures, the ancient monks will set up a variety of strange formations in the dungeon and the entrance of the dungeon. The formation is generally composed of multiple prohibitions. Each prohibition is set up in a different way, and the special mechanisms among them are even more varied, and the number is very large.

The copy of the Book of Fish, like all other copies, was created by an ancient monk. The ancient monk who opened up the copy of the fish book is called "Lu Fengxiao", he calls himself "the fish book scattered immortals", is a great monk who cultivates to the sky, he is respected by the younger monks as the "fish book master", and the secret realm of the sky he opened up is called "the copy of the fish book".

The copy of the fish book is rich in treasures, and there are many spirit trees, spirit beasts, spirit insects, spirit birds, spirit fish, and many powerful magic weapons and treasures that are not available in ordinary spaces.

Copies of the Fish Book will appear in the area of Qimeng Town in Qingcheng Province every three thousand years, and at this time, the sects and monks in the Wuyou Country will try their best to enter the copy in order to compete for the various treasures in the Fish Book Copy.

In order to enter the dungeon, it is necessary to find the entrance, and there is more than one entrance to the Fish Book Copy, and the monk can enter the inside of the Fish Book Copy from any of the entrances. However, at each entrance, there is a formation, and if the monk wants to enter the dungeon, he must crack this formation at the entrance. The entrance formation is divided into multiple prohibitions, and the first prohibition is organically composed of terrain, magic weapons, mechanisms, spiritual creatures, and so on.

The crystal ball shattered by the yellow iron egg with an arrow is part of the prohibition, and it is a magical magic weapon.

As a part of the prohibition, the crystal ball is usually hidden in any place on the wall of the first palace, and if the monk wants to break the ban of the first palace, he needs to find it and break it. After breaking the crystal ball, there will be a huge change in the first palace, during which the people of the first palace can reach the second palace through a passage.

After the crystal ball is broken, it will show magical abilities, causing great changes in the First Palace, and soon after, it will use its magical power to return to its original state after a short period of time, from a broken crystal ball to a complete crystal ball, and then disappear into the First Palace out of thin air. In fact, the crystal ball that disappeared out of thin air returned to a certain place on the temple wall.

This is the magic of the crystal ball as part of the ban.

When the crystal ball is restored to its original state, the first palace that has undergone great changes will be restored to its original state, and at this time, if the monk wants to access the second palace, he needs to find the crystal ball again and break it, repeating the process of the former.

Huang Tie Dan knows very little about things like dungeons, formations, prohibitions, and special mechanisms, so he naturally doesn't understand the role of the crystal ball. After Huang Tie Dan broke the crystal ball with one arrow, a huge change occurred on the field.

As soon as the crystal ball shattered, the small five-colored flower that was constantly rotating inside it suddenly bounced from its place to the huge ceiling of the First Palace. In the process of flying, the five-colored small flowers continue to rotate, and at the same time gradually change from small to large, from a small flower at the beginning to a huge flower. When the giant flower flies to the ceiling, its color instantly turns black, and as soon as its petals hit the ceiling, they immediately merge with the ceiling, causing the ceiling to turn black as well.

In the next second, the black giant flower grew savagely, and began to spread wildly on the ceiling, it continued to grow in all directions, first crawling all over the ceiling, and then spreading downward, countless black flowers, they quickly crawled down the four temple walls and numerous huge pillars. If this continues, it won't take a minute for countless black flowers to pounce on the people standing in the center of the palace and quickly overwhelm them.

When the black giant flower occupied the entire huge ceiling, there was originally a stone lamp on the ceiling that was constantly shining, and all of a sudden it was obscured by the black flower, and the whole world fell into endless darkness.

Everyone was frightened by this series of changes, and when the black giant flowers began to spread on the ceiling, everyone was stunned by this sudden change in this short period of time.

Everyone saw that as soon as the yellow iron egg shattered the crystal ball, the five-colored flower jumped to the high ceiling, and then the flower turned black, expanding, and continued to spread around, and it was about to spread to their side. Everyone saw that this black giant flower was bluffing, no matter how they looked at it, no matter how they looked at it, it was dangerous, they couldn't say it, if they were licked by this black flower, they would die and die on the spot.

In this regard, everyone didn't have time to scold Huang Tiedan, they only stayed for a long time, and immediately reacted, now it is important to escape, and they have to find a way to escape.

At that moment, just as the black flowers began to spread on the ceiling, the first palace where everyone was located began to shake violently. Everyone was worried about the attack of the black flower, and on the other hand, they were worried about whether the palace would collapse, and for a while, everyone became frightened, and they didn't know what to do.

When the black flowers have not completely covered the ceiling, everyone can still see everything around them clearly by relying on the light of the stone lamps on the ceiling.

At this time, the black flowers spread, the palace shook, and everyone could clearly see that a stone wall slowly grew from the ground at the small door where everyone entered, blocking it. When everyone saw this, their hearts sank, this small door was blocked, which meant that the escape road was blocked, and there was an imminent danger of black flowers in front of them, could it be that it was difficult to escape death today?

At the same time that the small door was blocked, the small door was far away, that is, the temple wall where the crystal ball was hidden just now, there seemed to be a huge mechanism pulling, and suddenly, this huge temple wall, it collapsed with a bang. The wall of the temple fell outward, and after a while, it fell to the ground, and in an instant, it turned into a huge flat and smooth ground, and the place where it had stood was vacant.

With the help of the stone lamps on the ceiling, everyone saw a huge passage appearing there. When everyone saw this, they immediately turned from sorrow to joy, this huge passage, needless to say, must lead to the second palace, and it is also a life channel for everyone to flee for their lives.

Everyone reacted, and at this time, seeing that the black flower was about to spread down from the ceiling, they had to hurry to escape to the huge passage opposite. However, when everyone was about to rush forward, they fixed their eyes and hesitated for a long time, because this passage is not simple. Everyone swept over at a glance, and immediately saw the situation in the passage, and couldn't help but turn sunny and cloudy, and their mood turned from joy to worry, and the heart that had just been at ease sank again.

It turned out that in this huge passage, there was a strange spirit worm wriggling around, they were numerous, and they seemed to crawl all over the passage, they were very large, and from a distance, they seemed to be much larger than the saber-toothed tiger. These strange insects, with a pair of big spherical eyes, glowing with a terrifying green light at this time, are crawling towards the first palace step by step. Seeing this situation, everyone was naturally stunned for a long time, not knowing whether to rush forward?

Although most of the people are middle-aged and elderly monks, and some of them have lived for hundreds of years, in the final analysis, they are just outer disciples of the Qingcheng Sect, and their knowledge is limited, and it is the first time they have come to the copy, so how do they know that this copy is full of strange things? They don't know the group of strange insects in front of them at all. In fact, these strange insects are called "green cockroaches".

The green cockroach is a relatively high-level spirit worm, which is a nineteenth-level spirit worm.

The color of its body is mainly blue and black, and its body is covered with small white round spots.

The green cockroach is very large, and it is twice the size of the saber-toothed tiger. In the front, it has a large head, and in the back it is a long body.

The head of the green cockroach is very large, like a balloon that is flattened from the front, the center of the flat ball, there is a huge mouth, giant eyes, tentacles and the like, the overall appearance, the face of the green cockroach is a little similar to the legendary high-level spirit animal "green cockroach", so it is named "green cockroach". In the center of the face of the green cricket, there is a large mouth full of sharp teeth, and the monk will die if he bites it, and if he does not die, he will lose half his life, and on the left and right edges of its face, there are a pair of huge green spherical eyes, and just above its face, there is a pair of long antennae.

The body of the green cockleworm is similar to that of a centipede, it is very long, covered with a hard blue and black shell, and the sides of the body are covered with long cyan feet, which can be used to crawl quickly on the ground or on the wall.
