Gu Xuan'er couldn't wait forever, and couldn't wait to urge, which saved being spoken.

"The way to do it is ...... Don't you all have the ability to sense ores......"

"yes, don't you have to mine some ore to leave? There are no ores in this dungeon! ”

Before Ning Tian's words were finished, Gu Xuan'er interjected impatiently again.

"It's okay for you to listen to Brother Xiaotian, Brother Xiaotian, say it quickly."

Originally, they were all waiting intently to hear what Ning Tian could say, but Gu Xuan'er suddenly interjected like this, and it was not easy for others to say, Gu Ling'er began to admonish. Fortunately, Gu Xuan'er had a big temper and didn't mind, and instantly quieted down and waited for Ning Tian's words.

"It's better that there are no ores in this dungeon. Because I have! We leave a piece of ore everywhere we go, and we know the edge of your perception range, and we put another piece, and I think about it, it doesn't seem to work. The stability of the triangle is the best, the second time we leave two pieces, and then play the vertical line of these two pieces of ore, so that we can make sure that we go in a straight line after that. There's no way to know where we are, but it's the easiest way to do it. ”

Ning Tian said beautifully, when he was in school, many people said, what is the use of going to school, you can't use it at all when you work in the future, Ning Tian didn't agree with this theory at that time, but there is no reasonable evidence to explain, after all, he has not set foot in society at that time, and now he can finally use practical actions to prove what knowledge is power.

"The stable surname of the triangle? Vertical line? ”

Ning Tian patronized himself and said, he didn't estimate the cognitive range of a few people and he couldn't contact him at all, he was extremely excited now, and the other four people were really confused, only to see Ning Tian happy.

"Hey! It's that I didn't make it clear, you see, that's what happened! ”

As he spoke, Ning Tian drew on the ground as he spoke, trying to organize some words that they could accept to explain this method.

"Oh, I see, it shouldn't be a problem. Let's go now! Time is of the essence! ”

The first Gu Biao who reflected, he also simulated the feasibility of this method in his heart, and the final conclusion was of course passed, and after thinking about it, he urged it. It's not that he's afraid of death, it's that he feels sorry for these people, and it's really uncomfortable to let a few people risk his life here.

"Brother Xiaotian, do you still have enough ore?"

Gu Xuan'er continued to ask questions pointedly, and her interest in asking questions was not restrained in the slightest because of Gu Linger's admonition just now.

"This ...... It's really hard to say, you see, these are not enough! If it's not enough, I can't help it, and then I'll have to resign myself to fate! ”

Ning Tian said as he took out a few bags of copper ore from his ring that he had left before. The existence of these ores was known only to him and Gu Ling'er, and it was really the first time that others had seen them. Originally, I was counting on these ores to make some money for myself, but now I have to take them all out when I encounter this situation.

"Well, I don't think it's necessary. We can divide the two groups, and I will give them to your royal highness. Once you've placed the ore in the next place, I'll put it away and move towards the next ore, and then you can keep going, and I'll just keep collecting the ore you left behind. That way, we don't have to waste a piece. ”

Gu Biao's mind had been thinking about this method since just now, and wanted to overturn this method from all aspects. This is a natural contrarian thinking, and he knows that as long as he cannot disprove it, this theory is correct. So when Gu Xuan'er raised that question, he was thinking about it, and now he has proposed this feasible plan.

"It's good! Then you'll have to work hard. There were a lot of us just in front of us, and we were a little sure of what happened to the thing. We'll wait for you when we've scattered enough ore in our backpack, and then we'll continue to use those ores when we converge, as there are too many ores to affect your movement speed. Without further ado, let's get started! Let's choose a direction, which direction do you think might be closer? ”

Ning Tian was in a good mood when he heard this method, and all the ways that he could save money for himself were good methods. He was also very anxious at this time, not because of his own safety, but because he wanted to help Gu Biao complete his task as soon as possible, so that he could go back to participate in that competition.

In the end, the task of choosing the direction still fell to Ning Tian, and the others were very stunned when they made this kind of decision that required full responsibility. Ning Tian didn't care about thirty-seven twenty-one, closed his eyes and turned around, heading towards that one.

The journey was quite smooth, and there were a few places in the middle that were relatively close to the top, but fortunately they were not discovered by the roar above. I don't know how long it took, but I finally arrived at a place that sounded quiet.

"This is it?"

Gu Biao was the last to arrive, and he knew that he had arrived at his destination by looking at the posture of several people, and asked after confirming his surname.

"Well, let's go here, there shouldn't be any Roar on it. Come, give me the ore first, and I'll put it away first. Let's go up for a while, don't go out first, let's see the situation outside, the best thing is to find Yang Biao's nest first, and go straight to the past after going out, there should be few in the nest now, let's withdraw after getting the eggs. But the question arises again, what if we evacuate? If you don't do it well for a while, it will definitely attract the attention of both parties, and when the time comes, eighty percent will be attacked by both parties at the same time, so it is basically not advisable to go back to the original way, is there any other way? ”

Ning Tian had thought about this question many times on the road, but in the end, he didn't come up with a relatively safe solution, after all, his understanding of this world was still too superficial.

"I've thought about this before I came, and you're sure you're right to listen to me."

Everyone is an individual, and their existence is singular and irreplaceable. Gu Biao materialized this problem very well at this time. He said a method that no one else knew, to be exact, a method that no one else in the room knew.

"I'll just say it! It certainly won't be the same way back! It sounds like a good idea, but it's not easy. It depends on the situation when the time comes, and if you can not alarm these guys, try to choose the same way to go back. ”

Ning Tian didn't seem to have much grasp of this method, and in the end, he would rather choose to return the way he came than choose the method proposed by Gu Biao, what kind of method did Gu Biao propose?
