When they arrived at their destination, standing in front of the spirit boat and looking at the dense fog covering the sky in front of them, Chu Han found that this place was indeed very strange.

These dense fogs are almost like substance, like an ancient beast that wants to eat people, and anyone who enters this thick fog should not think of it.

Compared to the fog on Cloud Island, it is like an ant compared to an elephant, which is nothing but a small thing.

Moreover, the scope of the dense fog here is also extremely wide, and from a close distance, it looks like the feeling that the mainland gave him when he first left the continent, and the edge of this fog is extremely smooth, as if there are two covers covering the fog inside, Chu Han finally knows why there is a big array here.

"Little brother, you see, this is the thick fog that the old man said, the dense fog in this is the same as that of Cloud Island, not only can block the line of sight, but also block the divine consciousness, and the degree of blocking the divine consciousness here is even more powerful, the same divine consciousness, if it can sweep ten miles in Cloud Island, it can only be swept to one mile here! So once you enter the range of this dense fog, you will soon lose your way and never get out again. ”

The white-bearded old man looked at the mist in front of him with a somewhat solemn face.

Chu Han's expression moved, and he tried to use his divine sense to get close to the mist, but as soon as he got closer, his divine sense was like a mud cow entering the sea, and there was no news.

"It's really evil!"

Chu Han was secretly shocked in his heart, but everyone else had an expression that he had already known this.

"Little brother, I guess you have also tried it, the fog here is indeed under a large array, after all of us investigated it together, we have some understanding of the formation here, this is the information we have gotten. The white-bearded old man threw his hand away, and a piece of jade flew towards Chu Han.

Chu Han took the jade slip, and after perceiving it, he found that all the things recorded in it were some professional things about the way of formation, and he couldn't understand many places.

However, it doesn't matter if he doesn't understand these theories, he is now using the Eye of the Law to look at the big array, and he can still see the lines of some formations, and gradually, he found some patterns......

When Chu Han was concentrating on the formation, one of those condensation realm formation mages walked out.

"Senior, these are the results of our previous research, I don't know what you can see?" Although this man is older than Chu Han, it is a customary habit for a martial artist with a low realm to call a martial artist with a high realm a senior, so that no one feels strange.

Chu Han ignored him, he was rapidly calculating these lines in his heart at this time, in his opinion, although these lines were more complicated than those of Pearl City, the range of formations here was many times larger than that of Pearl City's city protection array, so the formation patterns here were also much clearer and obvious, and many laws could be quickly summarized.

And since his soul power has been strengthened many times, his computing power has been much stronger than that of him on Earth, comparable to a slightly inferior computer.

Seeing that Chu Han ignored him, the man was annoyed in his heart, and his voice raised by two points, "Senior, I don't know ...... you?"

"Shut up!"

It was Chu Han who spoke, he was rapidly calculating these formations at this time, how could he have time to pay attention to this man.

The man's face was slightly red, he didn't expect Chu Han to be so faceless, how could he, who was usually arrogant, endure it? Even if the other party was a Yuan Dan Realm martial artist, he had to say that Chu Han couldn't face him in front of the Duan City Lord.

He was about to say something more, but was pulled by his companion, who shook his head at him and signaled him not to be impulsive, so he took a deep breath and didn't have a seizure.

Everyone was waiting for Chu Han, and they also found that Chu Han was paying attention to this formation, so they waited patiently.

When the man saw this, he secretly disdained it in his heart, he thought that Chu Han was just forcibly delaying time, and he would estimate that he would see some inconsequential things like them at most.

However, the white-bearded old man was very confident in Chu Han, and looked at Chu Han with a smile.

Time was slowly passing, and after a while, Chu Han's eyes suddenly lit up, and he turned his head to look at the white-bearded old man.

"City Lord, I have already seen some doorways, but I still need to deduce it, so it will take some time. ”

The white-bearded old man's expression was also lifted, "How long?"

"Hmm...... Five days!"

Chu Han said, he has now figured out the basic principles, just like the axioms in geometry, and figured out the essence, all that remains is to deduce a theorem according to the axioms, this process according to his estimate, about three days, and the five days he said is just to give himself a buffer time.

"As long as five days, no problem!" The white-bearded old man was overjoyed, you must know that after he led these formation mages of the Condensation Realm to come, it finally took a month to get some of the things in that jade slip, and Chu Han only glanced at it a few times now, and he was sure that it could be completed in five days, which was a big surprise for him.

"Okay, now I'm going to start deducing the formation, I hope no one will bother me these days. Chu Han said indifferently, glancing at the man who jumped out before as he spoke, and his intention was self-evident.

"No problem, little brother, now you're alone, we'll go back to our room now. The white-bearded old man said, this spirit boat has its own defensive formation, and the total energy can withstand a blow from the Venerable, so there is no need to worry about the sudden appearance of a sea monster, if there is really a sea monster that the spirit boat can't withstand, then there is no point for them here.

"Then it's a few troubles!" Chu Han said, and then sat down cross-legged by himself, his eyes widened, and all the formations of the dense fog array were clearly reflected in his mind.

"According to the law I saw before, these two branched formations should be able to combine into a new formation......" Chu Han made a defensive formation around himself before devoting himself to the calculation.

While Chu Han started to calculate at high speed, the others returned to their rooms at this time, this spirit boat was very large, so even if Chu Han occupied a large area, the other people's activities were not small.

"Brother Zhang, you were a little impulsive just now! I saw that after the Duan City Lord came back, his face was not very good-looking. ”

"Hmph, I just can't get used to the way he drags, a little kid, how can he compare to those of us who have been immersed in the way of formation for decades?"

"Brother Zhang doesn't have to be anxious, after five days, that kid is a mule or a horse, it is naturally clear that if he doesn't have that strength, City Lord Duan will naturally not get used to him anymore. ”

"You're right, I'm a little anxious, no matter what this kid has planned, after five days, naturally everything will be clear!"
