As these mermen found their respective locations and controlled mechanisms, the entire Organ City was completely activated, and the more than 2,000 rescue troops who entered it looked a little confused when they looked at the Organ City that had instantly changed its appearance around them.

"Don't panic, everyone, I'm a formation mage, even if they have this organ city as a defense."

Seeing the panicked appearance of everyone around, the Supreme Elder of the Liu family finally couldn't sit still, and if it continued like this, people's hearts would be scattered.

Then, with the roar of the Supreme Elder of the Liu Family, a huge formation suddenly began to emerge on the ground around him.

With the appearance of this formation, the energy between the surrounding heaven and earth suddenly became agitated, and then the temperature around it actually began to rise rapidly.

Only about three or five minutes had passed, and the rich water vapor in the originally damp cave had been evaporated in an instant.

The coverage of this large array was huge, covering almost half of the city, and those mermaids had left their comfortable environment and actually began to become a little weak.

This dry, almost watery environment is the most uncomfortable for the mermaids, but fortunately they still have a protective mucus on their bodies, which keeps them from dying of dehydration.

It's just that the temperature around this is still rising, and if it continues like this, no matter who the merman clan is, even if they have slime protection, they will probably not be able to stand it.

Although the effect of the willow white ape's formation was powerful, at the same time, it also angered those mermaids, and one by one the trap beasts rose from the ground and slaughtered everyone.

And this is not over, there are still hidden weapons in the surrounding buildings, and the entire organ city suddenly turned into a killing array, and almost every corner has hidden killing machines.

For many years, these mermaids have been studying the Organ City under their feet almost every day, even if this Trap City was not built by them, but it has also been studied by them.

However, the rescue army is not vegetarian here, and a powerful magic weapon has played a powerful role in their hands, although these trap beasts are indestructible and powerful in attack, but their core is also controlled by these merman clans, as long as these merman clans are solved, these trap beasts will become a pile of scrap copper and rotten iron.

In such a fierce battle, a figure completely disappeared from everyone's field of vision after entering the Organ City.

As soon as this figure entered the Organ City, its figure slowly disappeared into the space, and in the blink of an eye, it had disappeared without a trace, and then he flew past everyone and flew towards the square in the center of the merman clan.

This figure is Yan Yi, from the beginning of the fight, Yan Yi was not prepared to help these people, if it weren't for the benefits, Yan Yida was not prepared to make a move from the beginning, let alone help them break through the city gate.

And after entering the Organ City, Yan Yi had already activated the Imperial Beast Treasure Treasure, borrowed the ability of Xiaoying, and used Xiaoying's stealth ability to quickly cross all the war zones and come to the center of the Organ City.

According to Yan Yi's guess, the most valuable thing of these merman tribes is most likely to be in the cave where the shark tribe is sacrificed, and Yan Yi has been eyeing this place from the beginning.

It's just that the deduction has never had a chance to sneak in, and now all the merman clans have gone out to fight those rescue troops, which just gives Yan Yi a perfect opportunity.

Yan Yi lurked all the way to the outside of the Shark Clan's sacrificial cave, before there were some seventh-order and eighth-order guards guarding the door here, and even inside the door, there were a number of masters guarding the house, but now this place is empty, and all the guards have been transferred to the front line.

Yan Yi looked at the mansion in front of him, which was not guarded, and didn't even want to hide, so he swaggered in directly from the main entrance.

"This merman sacrifice is really going to enjoy it, puff, puff, this is really luxurious."

It was the first time for Yan Yi to enter this courtyard, but this entry really scared Yan Yi, the decoration here was so luxurious that even Yan Yi couldn't help but be a little jealous.

The lighting here is not actually used in the original lighting facilities of the city, but all the night pearls are used for lighting, and after entering the gate, there is a courtyard of nearly two hundred square meters, all kinds of jewels and corals and some giant pearls and gems are decorated here, and even the ancient palace is not so luxurious.

However, although these visual effects are shocking, they are of no use to Yan Yi, after all, although these things are gorgeous, they can't be exchanged for energy cores.

Yan Yi only glanced twice in this courtyard and then decisively rushed into the house inside, there is only one huge house in the entire mansion, from the outside, this house covers an area of seven or eight hundred square meters, as if it is a palace.

Yan Yi went straight through the path in the garden and came to the front of the house, but Yan Yi didn't enter the house without hurrying, not because he didn't want to, but because he couldn't.

Yan Yi could feel that there was a looming energy fluctuation around the open door house in front of him, according to Yan Yi's understanding, the only possibility of this energy fluctuation was that there was a formation around it.

"Xiaoxi, help me scan the formation here for any danger."

Yan Yi, who didn't know anything about the formation, had no choice but to ask Xiao Xi first.

"Don't worry, master, this is just a second-order trap, the master is not in any danger, and it can be easily broken with the master's strength."

After receiving Xiao Xi's affirmative answer, Yan Yi breathed a sigh of relief, after all, those two mermaid clan sacrifices were masters of ninth-order strength, and maybe there would be any advanced formations.

And now, under Xiao Xi's reminder, Yan Yi relied on his powerful spiritual power to crack the formation in front of him with great ease.

After the formation was broken, there was no longer any obstacle to Yan Yi's footsteps entering the house.

It's just that Yan Yi didn't notice that the moment he walked into the house, an undetectable energy flashed by, and the merman clan priests who were far away on the battlefield also felt a shock in their hearts at the same time.

"It's not good, someone has broken into my mansion, master, I'll go back first, and the command here will be handed over to you."

When he thought of the treasures he had collected, he couldn't sit still, and after hastily handing over the command of the battle to the previous sacrifice, he hurriedly thought about his mansion and ran back.

At this time, Yan Yi didn't know that he had been discovered now.

Yan Yi who would be this would have been shocked by the rich energy in this house.

"I'll go, this is really a tyrannical thing."

When Yan Yi sensed the surroundings through his spiritual power, he discovered the reason for the strong energy here, and there were nine spirit gatherings in this house.

However, this is not the key, what can gather so much energy is the formation eyes of these spirit gathering arrays, and the formation eyes of each spirit gathering array here are actually filled with low-grade spirit stones.

Such extravagant extravagance really surprised Yan Yi.

"Made, these mermaids are so extravagant, it seems that this trip has been fished, Xiaoying will help me detain all the low-grade spirit stones here for me."

Looking at the lower grade spirit stones that were constantly exuding energy all around, Yan Yi's saliva was about to stay, and a bandit-like momentum suddenly burst out from Yan Yi's body.

With a wave of Yan Yi's big hand, the small shadows on the side suddenly turned into nine phantoms and came to the position of the central array of the nine spirit gathering arrays, and in the next second, the energy that was almost liquefied was slowly thinned out when it was still rich.

"Xiaoxi, come out and receive the goods, and absorb all these low-grade spirit stones for me."

Looking at the lower-grade spirit stones in front of him, Yan Yi was also in a good mood, and hurriedly exchanged Xiaoxi and came out to exchange energy cores.

"Okay master, these low-grade spirit stones are worth a total of five energy cores, I'll help the master exchange them."

Xiao Xi's eyes swept and he knew the value of these low-grade spirit stones.

"Huh? Is it worth it? These are nine lower-grade spirit stones! ”

However, the value of these lower-grade spirit stones was beyond Yan Yi's expectations, and the nine lower-grade spirit stones were only worth five energy cores.

"Master, due to the arrival of those spirit gathering arrays, part of the energy in these lower-grade spirit stones has been consumed, and it is already worth a lot."

"Okay, okay, let's exchange it all, it's really unlucky."

In desperation, Yan Yi had no other way, he could only blame this merman sacrifice for being too extravagant and wasteful, otherwise it would be enough for all Yan Yi to be promoted, but even if it was like this, Yan Yi would have made a lot of money.

After searching the entire hall and finding nothing of value, Yan Yi also began to search room by room.

It wasn't until Yan Yi searched the innermost room, that is, the bedroom of the merman clan's sacrifice, that he found a more intense energy fluctuation in the end.

All of this energy comes from a treasure chest in the sacrificial bedroom of the merman clan.

There are dozens of heavenly and earthly treasures hidden in this treasure chest, as well as all kinds of magic weapons, if the merman clan does not have a storage magic weapon, those energies are emanating from these heavenly and earthly treasures.

"Stop the thief, or I will let you break your body into pieces, and you will be born if something happens!"

Just when Yan Yi was about to put this treasure chest into the system space, there was a sudden burst of shouts from outside the door, and the merman sacrifice had still rushed back.

In the face of the sudden change, Yan Yi did not show the slightest panic, his eyes were fast, and after putting the treasure chest into the system space, he turned his head to look at the merman sacrifice behind him.
