After everyone remembered the use of the spirit rune and the self-detonation beads, Bai Xingkong let everyone rest in place, and after confirming that everyone had recovered to the best state, the action officially began, and at this time it was already the ugly time that passed, that is, after three o'clock in the morning.

Bai Xingkong took the lead in front of the horse, and the rest of the people followed from behind, everyone was very careful when moving, even if the imperial weapon was flying in the sea, he deliberately controlled the magic weapon brilliance, so as not to produce dazzling light, so it was discovered by the mermaid people.

Now that everyone's location is very close to Jiyuan City, the number of mermaids here is naturally more than in the wild area, and the chance of being discovered has also increased a lot. In order to strengthen the concealment, Bai Xingkong also deliberately took out a blue handkerchief, instilled aura into it, and threw it directly in front of everyone.

After receiving Bai Xingkong's aura infusion, the blue handkerchief immediately grew larger, like a large light blue curtain, blocking the six of them behind. This is one of Bai Xingkong's magic weapons, it should be a relic from the Ouyang royal family, in addition to being able to hide everyone's figure a little, it can also break through the surrounding seawater, so that everyone's forward speed will not be affected by the resistance in the water, and speed up the forward speed.

The handkerchief that Bai Xingkong took out was called Bishui Aya, which was a water attribute magic weapon that could be attacked and defended, with a strong ability to control water, and the main material came from the hair of an ancient deep sea monster. The magic weapon is woven through hair, and after it is formed, it is placed in the deep sea, while using the principle of water pressure refiner to refine the magic weapon, and at the same time, with the help of the water attribute aura in the sea, the magic weapon can absorb more water attribute aura, so as to enhance its water control ability.

The reason why Bai Xingkong didn't use Bishui Aya before was naturally because this magic weapon had reached the level of a top-grade spiritual weapon, and with his current cultivation realm, he couldn't use it for a long time, and he would only use it at such a critical time. Now with the help of Bishui Aya's water control, when the group of six people advances, no matter how fast they are, it will not cause the nearby sea water to flow violently, and their whereabouts are well hidden.

The place where everyone was originally hiding was about two or three kilometers away from Jiyuan City, and with Bishui Aya breaking through the resistance of the seabed, it only took them a few minutes to reach the edge of the defensive formation and stand next to the huge aura shield.

Because the main function of the formation is to adjust the water pressure and water temperature of the defensive formation, when arranging, not too much attention was paid to the strength of the defense. In addition, this is the bottom of the sea, and the mermaid clan, as the overlord of the entire blue sea, will not have any unsightly people who dare to offend them.

Therefore, the defensive strength of the defensive formation in front of everyone is not very powerful, even if it is Bai Xingkong and the others, as long as they are given a chance, they can forcibly destroy the formation in just half an hour. However, there are a large number of mermaid people in the city, and the aura fluctuations generated by the attack and defense formation will definitely alarm the people inside, and Bai Xingkong and the others will not do such a stupid thing.

The location chosen by Bai Xingkong is far away from the gap in the formation, and the guard strength here is not large, even if he stays here for a long time, it will be difficult to be discovered. And the so-called formation gap is actually the entrance and exit reserved by the mermaid people, which is the passage for them to leave the city.

After all, the defensive formation had to be opened for a long time, and if there was no entrance or exit, then they might be trapped inside. Unwilling to close the formation every time he enters, so it is normal to reserve a few entrances and exits, those gaps have evolved into city gates, and there are guards patrolling for a long time, Bai Xingkong doesn't want to be discovered, so he naturally wants to avoid those preset formation gaps.

After confirming that no one had discovered their whereabouts, Bai Xingkong took out a rough map and began to search and grope around the neighborhood according to the instructions above. The others naturally didn't know how to get the map in Bai Xing's empty hand, but Su Yaowen knew very well that this was given to him by Shui Ningxiang, and what was drawn on it was the location of the newly replaced dark blue water stone, and it was also where the formation node was.

Bai Xingkong was very careful when he studied the map, for fear that if he made a mistake, he would fall short, but the progress was very slow. Fortunately, it was already early in the morning, and the city of the mermaid clan had not suffered any attacks for tens of thousands of years, so those guards were also very lax, and no one had found out until now, defending the small detachment outside the formation.

Along the edge of the defensive formation, Bai Xingkong took everyone to walk for more than ten kilometers, and finally found the place indicated on the map, and more than half an hour had passed.

"Miss Yin, wait a minute, you will be in charge of controlling the magic weapon, and the other two only need to help instill aura. Bai Xingkong took out a cone-shaped magic weapon, and then handed it to Yin Yushuang, among the three women, she was relatively stable and reliable, and it was reasonable for her to control the magic weapon.

"It's not difficult to use the magic weapon, you just need to make sure that the tip of the magic weapon is positioned, all the way to that place, you can tear the formation node apart, and wait until the dark blue water stone is exposed, and then you can take it out. Bai Xingkong pointed to a place in front of him, indicating that it was a formation node.

The position that Bai Xingkong pointed to was nothing special, that is, the corner of the shield, which looked similar to the one next to it. However, the formation node is hidden in the formation, if the formation is not broken, even if it is attacked, it will not be exposed, and it is not surprising that everyone sees anything special.

Others couldn't see that the location of the formation node was normal, but Su Yaowen was different, he had a supercomputer in his body, and for the calculation and analysis of various data, it was unmatched in the cultivation realm. Ever since she saw this defensive array, Xiaomi has been studying it, and even if she doesn't have a blank map, she can easily point out all the formation nodes.

Yin Yushuang carefully memorized the control method of the magic weapon, and after Jiang Hongye Yan Ziqi confirmed that there was no problem, the three of them instilled spiritual energy into the magic weapon at the same time. As the aura absorbed by the magic weapon increased, a burst of white light slowly appeared at the tip position, fortunately, Bai Xingkong had already prepared, controlling Bishui Aya to envelop everyone in it, and by the way, this burst of light was blocked, so there was nothing unusual.

It was worthy of being a magic weapon that could tear apart the nodes of the formation, and when the tip position was close to the light film formed by the defensive formation, it provoked bursts of aura collisions. It's a pity that the magic weapon seems to have a special ability that can cut off the aura transmission of the formation, so that the node position will not enjoy the aura supplement, and the defense will be broken little by little.

In just a few tens of seconds, a small gap had already broken through at the tip of the magic weapon, and it was still approaching the core area of the formation node little by little. If the formation node is broken, not only will the blue water stone inside be exposed, but there will also be a gap in the formation, and everyone can sneak into the formation through this gap, which is the real effect of this magic weapon.

You don't need to use violence, or completely master the core of the formation, you can break through the formation and sneak into the formation, such a magic weapon is unheard of. For those ancient ruins guarded by powerful formations, or caves left by ancient monks, such special magic weapons are their nemesis. It is undoubtedly a shortcut to make a fortune by allowing people to easily break through the outer formation guard, and use tricky methods to obtain various treasures inside.

Because of Su Yaowen's help, no matter what formation he encounters, no matter how powerful the defensive array is, he can completely crack the core of the formation through the calculation of the supercomputer, with or without this magic weapon. However, the other four women don't think so, the magic weapon specially used to tear open the gap in the formation, as long as it is obtained by the formation master, it is undoubtedly a powerful artifact.

Just like the previous annihilation battle of the Heavenly Dao Sect, if the three major forces at that time had been helped by this magic weapon, and then through the joint efforts of many formation masters, they would find the formation node to defend the great array, even if the Heavenly Dao Sect had more inferior spirit crystals as energy reserves, it would not be possible to last for half a year, and it might be broken in a day.

As the power of the magic weapon appeared, the four women's attention to it was also increasing, and the appearance of this magic weapon allowed them to once again see the richness of Bai Xingkong's wealth. Even the treasures that were taken out for them to choose from before and used as a reward were not as valuable as this magic weapon. (To be continued.) )
