Lin Feng didn't know how big the space of each floor of the Sky City was, how many sections each floor was divided into, and Lin Feng didn't know, if he was looking for them one by one, I was afraid he didn't know when it would be.

Therefore, destroying the formation is the most direct way, if there is a better way, I don't think Lin Feng is willing to choose to do this, this is also something that is forced to be helpless.

After following Selia through a few walls again, Lin Feng and the four of them finally came to the center of this second-layer formation, and during this period, Mo Yu and Pei Teh naturally showed their skills.

"I don't think it's any different here than anywhere else, where is that heart? It can't be Celia, you're mistaken, right? As soon as he arrived, Carmon began to mumble quietly, but the voice was especially loud in this somewhat quiet place.

Unlike Carmon, Mo Yu saw something else.

"Why aren't there pterodactyl guards here?"

As soon as they were reminded, Carmon and Pete also reacted, and immediately nodded in agreement, but their eyes involuntarily looked at Lin Feng, hoping to get an answer from him.

As if sensing the gaze shooting at him, Lin Feng raised his head and spread his hands helplessly.

"What do you think, Celia?"

"This is the heart of the entire second-layer formation, it is impossible to have no pterosaur guards, I think there are more guards here than anywhere else, but they are ordered to guard the heart of the formation, and they dare not show up at will, if they appear, isn't it equivalent to telling us the location of the center of the formation? So, I'm sure by the time we attack the heart of the formation, those pterosaurs will all be there. ”

"Haha! That's not right, come one to kill one, come to two to kill a pair! Of course, this kind of thing can only be said by Carmon, and I saw that he kept waving his fist as he spoke, and his fighting spirit was high.

"Carmon, don't be too careless, if you encounter a steady stream of pterosaurs, you will be exhausted!" Mo Yu didn't know if he was reminding Carmon to be careful, or what.

However, Mo Yu's words are not unreasonable, after all, this is also a lair of pterosaurs, and even Selia does not know how many pterosaurs will appear.

"Selia, we can't feel it at all, let alone see where the heart of the formation is, how can it be broken?" Suddenly, Peter, who had always been a man of few words, thought of a very important question.

"Don't worry! I have a way of revealing the heart. ”

"It's okay, otherwise our efforts to get here would have been in vain." After receiving a positive answer from Celia, Pete breathed a sigh of relief!

"I'm going to start, get ready! Let's attack the heart of the formation! After saying this, Selia began to silently chant the incantation, and then she waved her hands, and a white light spread.

It was like the dawn of dawn clearing the white fog of the early morning, and suddenly, Lin Feng and the four of them only felt that their eyes lit up, and the whole world suddenly opened up.

The white light flashed and disappeared, and when Lin Feng and the four of them saw the entire hall clearly again, a red gem in the center of the hall flashed with a somewhat demonic light!

"That red gem is the heart of the formation, attack it together, as long as you break the center of the formation, the entire big array will be broken, and the next thing is up to you." Celia reminded loudly.

Hearing the loud shouts, Lin Feng and the four of them were not ambiguous, and they all used all their strength to attack the red gem.

"Flame Blade"

"Hammer of the Falling Phoenix"

"King Kong Crush"

"Grimm Machine Gun"

The attacks of the four people landed on the red gem one after another, and suddenly a strong collision sound came.

It can be used as the heart of the formation, and it is obvious that the hardness of this red gem is not bad, and a fierce attack by the four people can only cause the red gem to crack a small crack.

'Whoa...'

Bursts of roars came, don't look at Lin Feng and a few people to know that it was the pterodactyl guards here, but the number was a bit much.

"It's a good time, I can finally have a great time today!" Carmon let out a loud cry and swept straight in the direction of the pterodactyl herd, like a hungry wolf that had seen sheep.

Lin Feng didn't stop Carmon's move, the current situation had to be someone to stop the pterodactyl's footsteps, since Carmon was willing, Lin Feng naturally wouldn't stop it, but his eyes had been on Carmon.

"Let's continue to attack the heart of the formation!" Seeing that Mo Yu was about to help Kamon, Lin Feng stopped his movements and said.

Although he was a little confused, out of trust in Lin Feng, Mo Yu didn't say anything and continued to attack the heart of the formation.

Perhaps because of the increase in strength, Carmon was killing happily at this time, not feeling tired at all, and every punch and kick was full of devastating lethality.

However, the pterodactyls that rushed over one after another did not mean to reduce in the slightest, and they could not be killed, and they could not be eliminated.

After a long time, Carmon gradually showed fatigue, and some could not support it.

"Lin Feng, come and help, I can't do it, why are there so many pterosaurs, it seems that they can't be killed at all." Carmon finally couldn't hold it anymore and began to call for help.

"Mo Yu, you go and replace Kamon and let him come back!"

Without saying a word, Mo Yu picked up his weapon and rushed out!

"Whew!" Carmon let out a long sigh and sat down on the ground.

"I'm so tired! With so many pterosaurs, we can break the formation, but rush out like this? Carmon asked anxiously.

"Don't worry! These pterosaurs are all derived from formations, and as long as the formation is broken, these pterosaurs will naturally disappear. Hearing Carmon's question, Celia on the side immediately explained.

"How do you know?" Carmon asked, somewhat surprised.

"Look at it, once these pterosaurs are killed, they will turn into smoke and disappear, which is completely different from those pterosaurs at the beginning, and their strength is much worse!"

As soon as Celia reminded him, Lin Feng naturally discovered this, "Since this is the case, then we will continue to work hard to attack the heart of the formation and strive to break the formation as soon as possible." ”

As soon as he heard this, Carmon couldn't take a break, and immediately stood up and attacked the heart of the formation with all his strength.

I have to say that to be selected as the center of the formation, the hardness of the red gem has indeed reached a certain height, if it is replaced by other gemstones, I am afraid that this formation has already been broken by Lin Feng and a few people.

Time is passing, and along with it is Mo Yu's physical strength.

"Pete, you go and help Mo Yu and let him rest!"

Seeing that Mo Yu was about to be unable to hold on, and that he had suffered some minor injuries on his body, Lin Feng immediately arranged for Pei Tee to take Mo Yu's place.

"Carmon, quick! The red gem is about to break! Come on attack! Seeing that the rift on the red gem was getting bigger and bigger, Lin Feng urged Kamon.

When Pete couldn't hold on anymore, Lin Feng stepped up by himself, replaced Pete, and faced the pterodactyl group by himself.

Speaking of which, against the pterodactyl group, Lin Feng is the easiest, Mo Yu, Carmon and Pete are all hand-to-hand combat, requiring constant dodging and then attacking, which consumes too much physical strength.

However, Lin Feng only needed to keep a certain distance from the group of pterosaurs, constantly throw grenades, and keep shooting.

Therefore, in the end, it was Lin Feng who insisted the longest.
