Chu Feng and Liwan didn't say much, they just snuggled up to each other.

When Nangong Yun floated to the surface, he rolled his eyes, and then said with a smile: "Hey, do you want to see the girl out of the bath again!"

The corners of Chu Feng's mouth twitched, don't turn his head, he glanced at him, a little displeased, but he also laughed and said, "Sister, why don't you let your sister take a look?"

Nangong Yun was slightly stunned, although she had already known that Liwan was a clever girl, but she never thought that Liwan was a little sharp-toothed.

She didn't know that Liwan was not so sharp-tongued, but she had done some fights with Chu Zi'er, and she naturally learned it.

Nangong Yun smiled, and immediately went ashore, steaming his clothes with luck, and said, "How much does my sister want to see?"

Liwan pursed her lips and didn't speak again, although she learned a little bit from Chu Zi'er, but she was not Chu Zi'er after all.

Ice Zhiqi followed and surfaced, and while climbing ashore, he said, "Those cold ice are indeed condensed by the ancestors. ”

Bing Zhiqi frowned slightly as he spoke, he had only dived for a while, and the Condensing World Knife was already struggling to get out of his hand, if it weren't for the fact that the Condensing World Knife was already a little close to his breath now, I was afraid that it would really get rid of him completely and leave.

Moreover, Rao is that he has evil ghosts in his heart, and he also feels a wave of shock at the blood and qi escaping from the pool.

Nangong Yun curled his hair before continuing, "Now do you understand what we are going to do?"

Bing Zhiqi nodded, his expression unchanged. In fact, he didn't care what he needed to do, he was only here because it was a request from Chu Feng, as long as it was Chu Feng's request, he wouldn't care much about the content.

Bing Zhiqi is such a person now, he remembers that he is kind and affectionate to him, so he will give back with all his strength.

Nangong Yun pursed her lips slightly before continuing: "I'll say it first, this matter is very dangerous...... It's not because it's really dangerous, it's because someone else will intervene. And the person who intervenes, I can't tell what kind of cultivation it is, I can deal with the cultivation of the peak of the ninth order, but if it is a higher cultivation, the end is bound to be miserable. ”

Chu Feng nodded, such a thing was naturally expected by him, and there were not too many surprises.

"So...... In the event of an accident, retreat without the slightest hesitation. Nangong Yun continued.

Bing Zhiqi looked at Chu Feng and was silent.

Chu Feng also looked at Nangong Yun with some surprise, he didn't expect Nangong Yun to say such a thing.

Nangong Yun was a little annoyed by Chu Feng's gaze, and said, "You want to stay and bury me so much?"

As soon as Nangong Yun spoke, he felt that he was a little too desperate and depressed to say this, and before the matter even started, he was already talking about the funeral.

Since they are all so pessimistic and hopeless, what is the need to continue?

Nangong Yun sighed slightly, and just wanted to say something encouraging, but Chu Feng had already slowly spoken: "Okay." ”

Nangong Yun was stunned, his sad mood suddenly disappeared, he glared at Chu Feng fiercely, and said angrily: "If you want to run, you will run, why are you so unrighteous?"

Chu Feng thought for a while before saying, "If you are doomed to failure, you still have to try with your life, it is a little unwise. If you keep your life, at least you have a chance to try next time, and you can easily lose your life, and even lose the chance to try again, that is a real failure. ”

Nangong Yun was a little annoyed, and said, "You are afraid of death, you are afraid of death, what are you doing with such a high-sounding sound?"

Chu Feng smiled shyly and said, "I'm not afraid of death." ”

Nangong Yun was silent for a moment, of course she knew that Chu Feng was not afraid of death, if Chu Feng was afraid of death, she would not have been involved in this matter at all, she just wanted to talk about it casually, but she didn't want to be said so seriously by Chu Feng.

Of course, Liwan also understood Nangong Yun's thoughts a little, so he coughed slightly, and then said: "Sister still tell things, the current situation is only urgent." ”

Nangong Yun nodded slowly, their current situation was not so bad, the blood qi was under her control, and it would indeed take some time to intrude into the creatures farther away.

But of course, it is better and easier to deal with such things earlier than later, so you still need to hurry.

Several people gathered together and surrounded Nangong Yun in the center, while Nangong Yun folded a branch in his hand and began to paint with the ground as a sand table to describe it to several people.

The first thing Nangong Yun described was, of course, the two cores of this incident, Suolongtan and Qianlong Lake.

Suolongtan is shaped like a crescent moon, and Qianlong Lake is shaped like a disk, although the two are forty or fifty miles apart, but at this time, under Nangong Yun's description, they are finally connected.

This is originally a relationship between the upper and lower levels.

Suolongtan is not only vertically downward, Nangong Yun's feeling is more acute than a few people, she has already noticed that Suolongtan actually has a slight angle towards the direction of Qianlong Lake, this angle is actually very small, if the depth of Suolongtan is limited, then it is difficult to have an impact.

However, the depth of the Lock Dragon Pond is very deep, and the depth of thousands of zhang is enough to make this deviation reach a point that cannot be ignored - not to mention, no one knows how deep the Lock Dragon Pond is, because none of them have descended to the bottom of the Lock Dragon Pond.

Therefore, Nangong Yun suspected that the lowest layer of Suolong Pond was actually located at the bottom of the Qianlong Lake.

And the blood gas that leaks out from the spring in Qianlong Lake is the blood gas at the bottom of Suolong Pond.

This speculation is naturally not unreasonable, and it is enough to be believed, because there is no water source in Qianlong Lake at all, but it is naturally impossible to keep the water flowing all the time, and the only explanation is on Nangong Yun's speculation.

The best way to solve this big problem is ...... Naturally, it is to go down to the bottom of the Lock Dragon Pond and completely solve the root cause of the creatures and blood qi locked at the bottom of the Lock Dragon Pool.

But with the cultivation of a few people, it is obvious that this road will not work.

Nangong Yun has two plans, one is to cut off the connection between Suolongtan and Qianlong Lake, so that the Qianlong Lake located outside the Wu Kingdom will reduce the intrusion of the human world, but this method only slightly weakens the impact, because the blood and qi in Suolongtan will still continue to spread outward and intrude, and it is also difficult to effectively solve it.

The other is to strengthen the large array on the basis of the Great Array of the Wu Kingdom, completely lock the Dragon Lock Pond and Qianlong Lake into the formation, and use the power guided by the formation to compete with the blood qi.

This method can solve the problem relatively properly, but the difficulty is far greater than the former, because the area involved in this formation is too wide.

In order to include Suolong Pond and Qianlong Lake in this area, it needs to cover nearly a hundred miles of land - a hundred miles of formation, and a formation of this scale is really a bit arduous to be completed by four people.

And since Nangong Yun wanted to solve this problem, she naturally wanted to be able to solve this problem more properly, so after thinking about it again, she decided to choose the latter and use a hundred-mile array to solve all the problems.

This is an almost impossible task for the four of them.

"But it's almost impossible, but that doesn't mean it's absolutely impossible. Nangong Yun ended with this sentence, wanting to boost his morale, but except for some reactions from Liwan, Chu Feng and Bing Zhiqi did not have any obvious changes.

Nangong Yun just wanted to continue talking, but Chu Feng had already shook his head and said, "This won't work." ”

Nangong Yun frowned, she subconsciously wanted to say something, but she thought that Chu Feng did surpass her by more than one level in terms of formation attainment, so she still obediently closed her mouth, wanting to hear Chu Feng's high opinion.

Chu Feng was silent for a moment before he said, "Even if you have enough materials, you won't be able to set up such a large array at all." ”

Chu Feng had been helping Nangong Yun set up a formation to channel the diffusing blood qi for the past two days, so his knowledge of the leylines in this vicinity was far better than that of Nangong Yun.

"We don't have the support of the Wu Kingdom, although we know the operation of the Great Array, but we have never been able to fully call the Great Array of the Wu Kingdom, with this large array occupying the leylines, it makes the leylines within a range of 100 miles extremely thin, and it can't support such a large array at all. Chu Feng paused, pondered for a moment, and didn't wait for anyone to ask how much range was needed, he had already spoken, "If you want to support such a formation, I'm just afraid of ...... At least a large array with a range of three hundred miles is required. ”

A large array with a range of three hundred miles, a formation of such a size, for four people, may not really be impossible to complete, but the difficulty has increased more than ten times above the large array within a hundred miles, this is not a question of one plus one equals two after all.

Nangong Yun didn't have that much time, she knew that there was not much time left until her mind was completely eroded by her blood qi, and she couldn't wait.

"Then cut off the connection between Suolongtan and Qianlong Lake. "Nangong Yun has no better way, he can only retreat to the second, even if it only slows down the spread of blood qi in a short period of time, it is better than not doing anything.

Nangong Yun looked at Chu Feng's expression as he spoke, Chu Feng did not nod or shake his head, but frowned slightly, as if he was in deep thought.

Nangong Yun didn't speak, just quietly waited for the result of Chu Feng's thoughts, she was a self-aware person, so she didn't have the slightest intention of forcing a decision at this time.

And Bing Zhiqi and Liwan didn't have any ideas, on top of the formation, Chu Feng's attainments didn't know how much higher than them, and naturally there was no room for them to speak.

Chu Feng's silence lasted for about half an hour, and then a glimmer of light flashed in his eyes.

Nangong Yun caught that fleeting light, and she could see that Chu Feng should have a way.

"We have another method, but this method, we need to divide it from both ends. Chu Feng coughed a few times to make his voice less hoarse and low before continuing, "This requires cooperation between us, and once the cooperation fails, I don't know what the result will be." ”

Nangong Yun was slightly silent for a moment before he said, "What do you say is the solution?" ”

"Hedging. ”
