"Look. The Northern Underworld War pointed to the fog in front of him and said.

"I can't see. Qin Shaojie replied very sincerely.

"Yes, it is invisible. The Northern War laughed. "It's because we can't see that we can't get out. ”

It turns out that when a person or animal is blindfolded or has little visibility to see, he often thinks he is walking in a straight line, but when he can see something, he finds that he is walking in a circle. ”

"And this kind of thing?" Qin Shaojie asked in surprise.

"Yes, someone has done experiments. Northern Underworld said. "Do you know why migratory birds can find habitats that humans can't find? It's because they have this sense of the outside world, like water, which humans can't feel, but they can feel water from hundreds of kilometers away. Isn't that weird?"

"Big brother, are you here to give me a biology lesson, or are you here to give me a science popularization?" Qin Shaojie asked depressedly, now that you are talking about people, why are you involved in birds again?

"Don't worry. Northern Underworld said. However, when the bird's eyes were blindfolded, it was discovered that it was also flying in circles in the air. ”

This means that when you can't see, you're not walking in a straight line as you think you are. ”

"You mean, the reason why we haven't reached the bottom for so long is because we're just going around in circles?" Qin Shaojie asked suspiciously.

"That's right. Northern Hellwar nodded. "We can give it a try, Onihime, and lend you Kuroya a use. ”

"What are you doing?" Dou Ruomei seemed to be quite interested in the Northern Underworld War Small Lecture Hall, suspended in the air out of thin air, and Hei Aya was already holding it in her hand.

"You black silk can be long or short, you use our current place as a fulcrum, and then we pull the other end and continue to fly down, if what I said is correct, then wait a while, we will see the end of this black silk. ”

"That's a good idea. ”

With that, the three of them continued to fly down according to the words of the Northern Underworld War.

Another ten minutes passed, Qin Shaojie's face was not very good-looking, and the face of the Northern Underworld War was also extremely serious.

"As it turns out, you're wrong. Qin Shaojie said.

"I was wrong. Northern Hellwar said with a frown. "How is this possible?"

It turned out that what the Northern War said was wrong.

It can't be said that it is completely wrong----- he is right, but the reality is not like that.

After all, the three of them didn't land, and they didn't see the end of the black silk, which proved that they weren't going around in circles at all.

"What should I do?" Dou Ruomei asked as she withdrew the black silk and looked at the Northern Underworld.

Although her cultivation is higher than that of the Northern Underworld, she is not as proficient in the Wheel Formation as the Northern Underworld.

Northern Shenzhan frowned and didn't say a word, as if he was thinking about something.

"It doesn't make sense. The Northern War said to himself. "If it's not like I said, then how come I've never seen this formation?"

"If you want me to say, let's go up first. Qin Shaojie proposed. "It's not too late for us to come down when you think of a way, it's better than running around here like a blind man. ”

"Okay, let's go up first, let me think about it, I haven't seen this formation, and we can't artificially destroy that fog, but I'm sure this array must be in this fog. ”

So, the three of them turned around and flew upward, ready to find a way to come down and find out.

Half an hour passed, Qin Shaojie smiled bitterly and helplessly----- and the three of them found at the same time that they couldn't go up, couldn't go down, couldn't go up, couldn't go up, this state of not going up and down was really depressing.

"It's good now. Qin Shaojie said with a wry smile. "We're all trapped inside, can we just wait to die?"

"We are cultivators, and even if we don't eat or drink, we can't die. Northern Underworld said. "When I figure it out, we'll be able to get out. ”

"That's what I said. Qin Shaojie said. "But have you ever thought about it, what do we rely on to fly? ”

"Even if our cultivation is not low, but there will always be a time when the true yuan is exhausted, how long can you figure it out? a minute, an hour, a day, a year, or ten years?"

"When our True Yuan is all consumed, how can you still fly? Without True Yuan to control the magic weapon, it will become a pile of scrap copper and rotten iron. ”

Hearing Qin Shaojie's words, Dou Ruomei's face tightened even more with the Northern Underworld, and the brows of the Northern Underworld War furrowed even tighter.

Qin Shaojie's analysis is right, even if the immortal descends to earth, the true yuan does not come just as it comes, it always controls the magic weapon, even if the cultivation is profound, it will one day consume the true yuan.

It's like a saint warrior can't be strong without a holy coat, and a little Wukong can't transform without a tail, and in the same way, if a cultivator's true yuan is exhausted, it's no different from ordinary people.

The three of them were all frowning, all thinking about how to get through this sea of fog, but for a while, Sanquan didn't have any way.

Rao is Northern Underworld War, a person who has studied the formation method, also frowned, helpless.

"Oh, Qin boy, what did you just say?" was thinking about it, but he heard the Northern Hellwar shout.

Qin Shaojie was startled, looked at the Northern Underworld Battle, and asked. "What's the matter? I've just said so much, which one are you asking?"

"It's just that there is no true element, how are we going to be?"

"No True Yuan?" Qin Shaojie thought for a while and said. "Without Zhenyuan, we all fell down and died, so we don't need to ask. ”

"That's right, that's it. Bei Shenzhan suddenly laughed happily, like a child who got a favorite toy, and smiled very happily.

"Haha, I know, finally know. ”

"Big brother, what do you know? Say it and make us happy. Qin Shaojie said angrily.

"I ask you. Northern Shenzhan looked at Qin Shaojie and started his small lecture hall again. "You say, just over there, if you were just an ordinary person, would you jump off?"

"Damn, I'm not stupid. Qin Shaojie pouted and said. "It's smoky down here, and I don't know the depths, so a fool jumps down. ”

"Yes, if you are an ordinary person, you definitely don't dare to jump down. Northern Underworld said. "Just because you are a cultivator, you jumped down without any scruples, if I guessed correctly, this formation is designed for cultivators. ”

"Oh, do you think of a way to break the formation?" Qin Shaojie's eyes lit up and he hurriedly asked.

"I think so, but we'll have to try to find out. ”

"Then you don't hurry up. Qin Shaojie urged.

Oh, this guy is toothpaste, squeeze out a little bit, why is it so tiring to talk to him.
