"Huh, I'm so tired." As soon as I entered Freya's moving fortress, Catherine and Lina lay on the ground as if they were exhausted. Catherine gasped weakly and said: "I didn't expect this battle to consume so much physical strength. I doubt if I can hold on to it a few more times. It's only half an hour."

"Sister, don't doubt it. I'm not sure if you can hold on. I'm sure I can't hold on." Lina got up from the ground pitifully, without even the strength to heal herself, and let the wound roll out: "And you don't have to do it a few more times, it's very difficult to do it again. I have to admit that we all underestimated the strength of the enemy. Sister, it's difficult for your plan to continue. Of course, it's not impossible, but the hope is too small."

"Well, I admit that the plan has indeed failed." Catherine did not shy away at all and nodded, "In addition, if you don't treat it, I will not have a big problem. You probably will fall into a coma due to excessive blood loss."

"It's okay, I'm sure." Although Lina didn't care, she began to clean her wounds as she said, and then cast a healing magic trick: "Since that's the case, why don't we change the tactics, sister."

"You just said you had new ideas." Catherine nodded and said, "Let me hear it, what new ideas?"

"Wait for me." Lina accelerated her movements, and after healing the severe wounds on her and Catherine, she struggled to get up from the ground, walked to the grid for observation, and waved to the others to come. Several people gathered around the grid. Vivian, who was not tall, lay on Freya's back and looked in the direction Lina pointed: "I discovered a problem ten minutes ago, but because of lack of certainty, I have never dared to say it out, but since I don't have much hope now, it may be helpful to say it out."

"Stop talking nonsense." Freya said: "You look at the elder sister and you almost ate you. If you say so much nonsense, she will beat you up directly. Tell me quickly. Even if there is a problem, no one will blame you."

"Look at their formation." Lina shrank her neck and pointed to the enemy and said, "Everyone should have discovered it a long time ago. They are mainly concentrated on our side, but the further back they go, the looser they become. When they reach the other half of the area, they just stand loosely with a few people standing in defense. They often gather at a distance of six or seven meters, as if they are concentrating their efforts to surround us here."

"Yeah, this situation is very obvious." Catherine nodded and said, "Are you saying we just go around and search the other side?"

"No. That doesn't make any sense at all." Lina shook her head and said, "I can't see it here now, but when we both went out just now, you probably didn't notice it because you were fighting fiercely. But I was searching most of the time, but when I accidentally looked up a few times, I found something."

"I have a good premonition." Catherine asked, "Tell me, what did you find?"

Lina did not rush to say that, but asked Vivian to ask for a piece of paper, and roughly drew a few crooked circles on the paper. She pointed and said, "Look, this big circle outside is the range of this gentle slope, and then this is where we are."

"Your scale is wrong." Vivian and Freya, as scholars, could not tolerate such imprudent graphics the most. Vivian grabbed the pen and drew a relatively standard position map on the paper, and asked: "Then, please point the position of the other circle, oh. This is right, okay. Let me tell you, and you continue."

"Well, this is our position," Lina continued: "Then we searched along this range just now, and there was no gain. But I found that their position would change as we move, not only close to us, but also those who were loosely positioned behind them."

"This is normal," said Catherine. "Although they are under control, some of their combat instincts are still there, so they will naturally change their positions as we move. Is there anything strange?"

"It's normal to get here, but a strange problem is coming." Lina raised her head, her big eyes flashed, and said seriously: "I have observed it many times later, and even deliberately guided you to go to the wrong position several times. Finally, I can confirm that there has been no enemy walking around this point within a radius of about three or four meters."

"Wait, my mind is a little confused." Catherine stopped Lina's words, frowned and thought for a while, saying, "But the distance between them often gets very large, and it's not surprising that there are a few meters of gaps."

"Yes, it's nothing to have a few meters of gap, but if they change their positions, the gap will remain there?" Lina said: "And, I saw with my own eyes that in order to change the position, a controlled sea clan could go straight but not walk, and deliberately went around an arc to avoid the range."

"So you think, where are the things we are looking for?" Catherine's tone also rose, and she said excitedly: "It is indeed very likely that this is the case. That thing is targeted at the sea clan, and of course it cannot be obtained by the sea clan. Even if it is controlled, it will not work. So just in case, the sea clans controlled by it cannot get close to it."

"Yes, that's what I think." Lina nodded and said, "And I think the possibility is very high."

Katherine suppressed her excitement and took a few deep breaths to calm her mood: "What about you two?"

"I didn't see the scene." Vivian said: "But if Lina observed correctly, there is indeed this possibility."

"I haven't paid much attention if Lina doesn't say it." Freya said: "When I observed the whole audience a few times just now, I vaguely remember that there was never a person standing in that area. Lina's observation should be correct."

"How is it, sister." Lina poked Catherine's waist with her elbow: "Are you interested in going to have a gamble together?"

"There is a great danger." Catherine frowned and said, "It is not only difficult to pass through almost all the enemies, but also if we make a mistake, we will be surrounded by many sieges. Then there will be no turning back, and it is very likely that everyone will die here in the end."

"Do we still have a way to go now?" Lina asked back: "Unless you are willing to leave Panis, we four can escape from a distance. The mission will fail, but we can still save ourselves. But are you willing to leave Panis? Not only do you not want it, but we three are not willing. So, we have no choice, whether we bet or not this time, it is the same, it is just a difference between morning and evening."

"Let me think. Let me think." Catherine murmured a few words in a low voice, paced in the fortress for several times, until Vivian sat back to the center of the magic circle to charge, she slowly shook her head: "No, there is something wrong with your plan."

"Sister." Lina shouted anxiously: "Now..."

"Wait for me to finish." Catherine said: "The plan needs to be changed. It's not that we'll go bet together, but that I'll go bet alone, and you'll stay here."

Lina smiled, sighed and shook her head, "You should know me too, my sister, you want me to stay here for my safety. I understand this, but do you really think I will agree? Do you think I will watch you risk your life and rush over? No matter what, two people can cooperate with each other and let you go alone? It's too underestimated me."

"No, I have my own reasons." Catherine did not give in. She insisted: "The previous few days, fighting with the controlled sea tribes in the deep sea gave me a deeper understanding of my mobile skills. I used to limit myself to the scope of plane warfare, but the battle in the sea allowed me to see the shadow of three-dimensional mobile warfare. So, I need to test my ideas in actual combat, if there is no problem. I can only engage in a very small-scale battle and rush into that area."

"What then?" Lina asked, habitually playing with the silver hair on her shoulders, "What if our idea is wrong?"

"Even if our idea is wrong, I can come back in the same way." Catherine said affirmatively: "Don't worry, I won't joke with my life."

"Even if you're right," Lina asked worriedly: "What if your test fails? Have you ever thought about it?"

"Haha, of course I thought about it." Catherine reached out and pinched Lina's face, and said as if she was coaxing a child: "Put your brain. If the test fails, I can't get through at all, so I will naturally be next to the fortress and can return at any time. Okay, I promise you that if my test fails, I will definitely come back and ask you to rush over with you. Don't be so nervous."

"Huh, do whatever you want." Lina was silent for a long time and breathed heavily: "You are the eldest sister, you have the final say. But remember, you promised us that you will accompany us in the future. If you quit halfway today, we will not forgive you."

"Of course, I will definitely come back safely. There is nothing scary about these controlled sea tribes." Catherine said seriously: "So, you can keep here with peace of mind and wait for the news of my victory. Believe me, don't forget that I am a knight, and the knight will never turn his promise."

"Okay, that's it." Lina began to chant prayer and exerted defensive magic on Catherine. Freya thought about it, took out a coin and stuffed it into Catherine's hand: "This is the prop that my father saved me from my life, a masterpiece of a demigod. When breaking it at a critical moment, it will instantly impose a force field on you, which can withstand the attacks under the demigod for three seconds. If there is danger, please use it. I don't want to think about the eulogy at your funeral."

"Thank you." Catherine took great care and put the coin in her pocket that was easy to pick up, and nodded vigorously in emotion.

"Sister." Vivian from the Formation Center raised his hand and threw a small box over: "Don't be reluctant to use the three top-notch healing potions. No matter how much money is, life is not important."

"Don't do this." Catherine smiled bitterly and waved her hand, "Don't act like I can't come back. I'm still optimistic about this plan. Okay, I'll set off."
