Abu directly erased the broken circuits that could be seen in the three-dimensional grid diagram, so that there were only forty-three passages left for people to walk.

"There's so much left that there's no choice. Huo Chi looked at the rest of the passage carefully, and still felt very tricky.

"Don't worry, of the remaining forty-three, twenty-eight have suddenly fallen or risen, and only fifteen have smooth roads. Abu continued: "And seven of the fifteen will get narrower and narrower. ”

"That's eight left, and that's a little bit more. Huo Chi found that although the number of channels was reduced to single digits, it was not easy to judge which one was better.

If you test these eight one by one, it may take too much time, and at least half of these channels will diverge into more forks. Abu's scanning range is limited, and he is reluctant to use more energy in a short period of time.

Even if you use Vibrating Crystal Sense, you can only scan it once in twenty-four hours at most, and if you want to scan farther away, you have to wait for the skill to cool down, alas!

"I also noticed something special when I was scanning. Abu noticed that Huo Chi was still staring at the grid map, so he reminded, "Have you noticed that although it looks like a confined space, there is air movement in this place?"

"Well, it seems to be a bit windy. Huo Chi said: "There are several passages leading to the ground, and it is not surprising that there will be wind. ”

"It's not surprising, but the wind in those passages is a little different. Abu said, "Look at the remaining eight passages, the third one counted from the left hand, and go in and see." ”

"Okay!" Huo Chi heard the words and walked straight to the passage that Abu said, this ice-melting passage was inconspicuous, and the entrance to the passage was not large, so he could only barely force the two of them to go side by side. But when Huo Chi stood at the entrance of the passage, he obviously felt that the air flow here was a little disordered.

"Abu, the flow of air here is chaotic, and it seems that some of the air flow has been sucked into the passage. Huo Chi noticed the unusual flow of air here, and stepped into the passage with some excitement.

"Are we going to go this way?" Su Qingqing followed, although she didn't know why Huo Chi chose this one in so many ice caves, she still walked into the passage with Huo Chi.

"Well, Qingqing, you try to feel it, standing here, there seems to be an air current passing forward. Huo Chi's senses were much sharper than those of ordinary people, and he could already clearly perceive that the air flow here was exactly the opposite of outside.

"It seems to be true!" Su Qingqing closed her eyes, as a sniper, she was also a little sharper than ordinary people, and it was this little bit of sharpness that made her feel the slight disturbance of the airflow here.

"Maybe this passage leads to the exit. Huo Chi walked to the edge of the passage and shouted to the white fox and Patassas not far away, "Mr. White Fox, Patassas, come here——!"

When the white fox and the sugar glider heard the shout, they immediately got up and rushed over, and Patassas ran to the entrance of the cave and looked at the ice cave with some concern, this ice cave was crooked and could not see the situation inside, she asked suspiciously, "Are we really going to go in?"

"Yes, there is air flow here and it is in a different direction than the air outside, so we can try this passage first. Huo Chi didn't say no, after all, he didn't know where this passage led.

"Well, there's a bit of a breeze. The white fox felt it intently, and also noticed that the air flow here was unusual: "Let's go in and have a look, it's better than waiting here." ”

Out of trust in Huo Chi, Su Qingqing and White Fox both agreed to enter this passage to have a look, and Patassas had no opinion, so the four of them carefully entered this passage.

"If I hadn't accidentally fallen into this place, I think it would have been quite interesting. Su Qingqing looked at the smooth ice walls around her, behind the thick ice, those dots of light looked colorful, walking in such an ice channel, it really gave people the illusion of entering a fairy tale world.

"Yes, I don't know what those glowing things are, why can't you see them at all in those places where there is no ice outside?" Patassas was also very curious about the glowing objects.

Huo Chi squinted, trying to see the glowing objects clearly, but no matter how good his eyesight was, he couldn't penetrate the ice.

Ice is not glass after all, and it is not even as transparent as water, and those colorful points of light hide in the ice, like colored light bulbs embedded in frosted glass, which look all faintly blurry.

"Abu, what are those luminous bodies?" Huo Chi suddenly found that when he carefully observed those light spots, the system seemed to mark the light points, but this time the system marks were a little unclear, and those words seemed to be fused with the ice.

"You'll find out in a moment. Abu said, "I need to regain my energy now, don't disturb me." ”

Abu replied casually, and then said no more. Regarding the system's regular tsundere behavior, Huo Chi knew very well that Abu would not answer any questions at this time, so he could only continue to move forward and stop bothering Abu.

"There is a fork in the road ahead, which one should we choose?" Su Qingqing found that in front of the passage, there were actually three forks in the road.

"I'll see. Huo Chi walked over quickly, carefully felt the air flow again, fortunately, among the three passages, only the middle one still maintained the same air flow direction, he nodded and said, "Take the middle one." ”

"Wait a minute, I'll make a mark. The white fox pulled out the long sword behind his back and carved an arrow on the ice wall with the hilt, and then re-carried the long sword.

Huo Chi knew that the white fox was lost and scared, as long as he encountered a fork in the road, he would make a mark, but these marks actually did not play a role for the white fox, because it was generally difficult for the white fox to return to the place where the mark was made, and it was impossible to check these arrows.

Everyone stepped into the middle passage chosen by Huo Chi and continued to walk forward, and when they came to the fork in the road again, more than twenty minutes had passed.

Huo Chi still concocted the same method, and chose the channel with the same direction of the air flow, and in this way, after several choices, Huo Chi himself had completely turned.

Fortunately, the airflow in this place has not been interrupted, and walking in the direction of the airflow allows Huo Chi to maintain a certain amount of confidence.

But there was still no change in the road ahead, which made Patassas a little anxious: "What are we going in?

"No... Huo Chi stopped when he heard this, Patassas was right, although they found the direction of the air flow, but they couldn't tell the specific direction here!
