Nan Qianjing naturally knew the power of the sea waves, but with so many of them, as long as they worked together, they could still fight.

"Disciples of the Yu Clan, hurry up. We will go to the top first to set up a defense formation. We will hold out as long as we can!" Yu Zhichang said.

"Yes!" The disciples of the Feather Clan sped up, and everyone made way for them to go first.

Soon, everyone arrived at the towering mountain, and the disciples of the Feather Clan had already begun to set up the formation.

"The sea wave is expected to arrive soon, so everyone should be prepared." Bei Yaolan said in a serious tone.

"Strange, I didn't think the mountain was so high when I was at the foot of it, but I didn't expect it to be so high that it would reach the clouds." Nan Qianjing frowned. There were too many strange things about this place. What kind of secret realm is this? It's not the mermaid realm, but there are sea waves. It looks like a secret realm in the cultivation world, but it allows the forces of the devil realm to do whatever they want and control it properly. What is the secret here?

"The formation starts!" Yu Zhichang led everyone to activate the formation: "When the sea wave comes, everyone will input spiritual power into the formation. In addition to its own defensive function, the formation can also amplify the input spiritual power several times. If everyone works together, we can still withstand the sea wave."

Please, the strength of the Phoenix Guards and the two saints is no joke, and there are so many families gathered here, there are many elders, guests and other masters, and the proud ones are just inexperienced, not weak. Thinking of this, Yu Zhichang is still somewhat confident in the formation.

"I didn't expect that the Yu Clan, in addition to being good at alchemy, also has such high attainments in formations. You really are hiding your talents. No wonder such a stunning person like Patriarch Yu Yao emerged." An elder of a large family said.

"Senior, you have misunderstood. You may have got the order wrong. Yu Yao came first, and then the Yu clan rose to prominence in the art of formations. Formations are indeed not what the Yu clan is good at, but that was in the past. Today, the Yu clan has indeed improved a lot under the selfless teaching of the head of the Yu clan, Yu Yao." Yu Zhichang did not want the world to underestimate Yu Yao's achievements.

"Did the head of the Yuyao clan teach you this formation?" Old Xiao was very surprised. He originally thought that the Yu clan had kept something back, otherwise how could so many disciples who knew formations emerge after Yuyao emerged? Although this formation is not as difficult to practice as the alchemy, it is not something that everyone can practice, and it is not something that can be easily mastered. So they always thought that they knew it.

I didn’t expect it was Professor Yuyao’s. How did she achieve such rapid and huge progress?

"Here they come!" The voice from the crowd drew everyone's attention.

Huo Chen had tried to contact Yu Yao several times, but failed. He estimated that she was not optimistic. If she didn't come out, the thunder might strike her inheritance space. If she came out, the sea wave plus the heavenly punishment would really kill everyone! He couldn't help with Yu Yao's affairs, so he could only solve the problem at hand.

"The formation has been activated, but it can't hold up with just our strength. Everyone, quickly input your spiritual power into it! Don't hide your weaknesses, this is a moment of life and death." Yu Zhichang said, he knew the little thoughts of some people inside.

"quick!"

Seeing that the sea wave was approaching, the array's protection had already been activated, and Nan Qianjing took the lead in inputting spiritual power. If it were normal times, she would not bother to care about the lives of these people. Those who were willing to listen to her orders would be protected, and those who were unwilling would be driven as far away as possible. But facing the sea wave, everyone's strength was indeed needed.

Everyone had already felt the pressure of the waves. The sky was no longer visible, covered by the huge waves. The formation was visibly vibrating, and everyone input spiritual power into the formation, and the formation barely reduced the vibration.

"Such a huge wave!" Everyone was stunned. When they first heard it, they thought that everyone's reaction was too big. They didn't expect that it would be a wave of such power. If they didn't have any protection, they would probably have been flattened to death.

At this time, everyone put away their contempt.

"Why hasn't it happened yet?"

"Yes, this wave of sea waves should have passed, why is the formation still in shock?"

Master An and the elders of the Shangguan family raised questions.

"The sky is still covered, which can only mean two possibilities. One is that we are flooded, and the other is that the sea wave has not ended yet." Huo Chen said.

"Flooded? Not likely, the mountain is so high. But if the sea wave hasn't ended yet, there would be enough time for it to come three times, which is also not likely." Shangguan Heng said.

"The sea waves are so dangerous, Yuyao, I wonder what the situation is?" Shangguan Liu's interruption distracted everyone's thoughts.

"Well, it's such a dangerous place. If she stays with us and unites with us, our chances of escaping together will be greater." As if sensing the strange looks from everyone, Shangguan Liu spoke. He looked calm, but he was actually very panicked inside.

It is rumored that Shangguan Liu and Yuyao are not getting along, but this doesn't seem to be the case. Rumors are just rumors after all, and it seems that the Shangguan family and Yuyao have a good relationship. Some people think so.

Nalan Wanlan was thinking about Nalan Mingde. If he encountered this situation, he would not be able to escape.

Boom—something hit the formation, causing a loud noise.

"Look!"

"That is!"

I saw a corpse being hit onto the formation by the sea waves. The corpse was instantly torn into pieces. Before I could see clearly, it was carried away by the waves.

"Increase spiritual power!" Yu Zhichang sensed the instability of the formation.

Everyone had no choice but to squeeze their exhausted dantian once again to continue outputting spiritual power.

Everyone understood that if the sea waves continued, they would not be able to sustain the formation for too long.

At this time, Yu Yao also saw the situation outside, but she couldn't go out. The heavenly punishment was almost brewing and was about to fall. She was struggling to decide whether to gamble with the space and take a risk, or to go out directly with the heavenly punishment and split the secret realm. However, if she split the secret realm at this time, then the countless monsters from the devil realm inside would be randomly thrown into the mainland of cultivation, which might harm countless people.

But the inheritance space is her trump card, it is her life-saving thing. She is not a saint, she is willing to sacrifice for the one she loves, but she can't sacrifice too casually.

Yu Yao gritted her teeth and summoned all the contracted beasts and pterosaurs.

"You guys carry it for me first. I'll be out for a while." Yu Yao disappeared in an instant.

"What is this? Damn it, it's a punishment from heaven! Boss, what are you doing to me!" The space was filled with the roar of the pterosaur.
