"What's the help, how can I help!" Fang Lin wondered, Ye Yuan, who had always been mysterious, once again made him scratch his head. Pen "Fun" Pavilion www.biquge.info

If Ye Yuan wants not to continue to get lost, then he should first judge his own position, the Abyss Howling Tiger is in the northeast direction of the camp, and now Fang Lin and the others are gathered at the north exit of the camp, then Ye Yuan is likely to still be in the northeast direction of the camp, at least in the north direction, otherwise two days have passed, if Ye Yuan has passed near the camp, the invisible line of the news jade will not jump until now, and Ye Yuan will have been able to contact the forest above.

Moreover, Ye Yuan judged that he should be under the ground in the northern part of the White Feather Mountain Range, with various passages crisscrossing and various inclined grounds, if it was a pure mountain, there would be no external force to support it, and it would have collapsed long ago.

Then the next step is very simple, through the displacement of Fang Lin and the change of the strength of the connection, Ye Yuan can roughly judge his position, and Ye Yuan is from the Hua country of the earth, and the basic mathematics of the Chinese people is at the strongest level on the earth, and it is very simple to carve out a coordinate in his mind and then judge his position, it is a simple thing for the Chinese people, not to mention that if Ye Yuan's abstract thinking is not strong enough, it doesn't matter if he paints on the wall or on the ground of the passage.

Even if Ye Yuan writes here, "Ye Yuan has cultivated to visit here in a certain year and a certain month", it will not necessarily be discovered after thousands of years, and no one will take pictures of it and post it on the "Internet" if it is discovered, there is no evolution of the technology tree on the earth in this world, Ye Yuan can put a hundred hearts, besides, Ye Yuan's abstract thinking is not so weak.

Ye Yuan weighed these things in his heart, and said: "Brother Fang, next you are going to the north, you can write down the number of steps you have taken, tell me every hundred steps you advance, and tell me if you change the direction, if I ask, you also tell me the total number of steps you have advanced, it's as simple as that." ”

"It's that simple?" Fang Lin couldn't believe that after two days of Ye Yuan's silence, it was so easy to ask him to help, he really couldn't figure out what he needed to help with this little favor, and what would help Ye Yuan.

But this can't be blamed on him, in this world that advocates force and cultivation, the mathematical system has not been developed at all, and most people even if they have cultivated to the realm of Xuanhou, it is estimated that it will only be the simplest addition, subtraction, multiplication and division, like the power of cultivating the earth law, the deduction ability may be extremely strong, but mathematical knowledge is the foundation, no matter how strong it is, it will not be much stronger.

"Yes, it's as simple as that!" Ye Yuan didn't think about it that much, naturally he didn't know that Fang Lin didn't want to go with him, but it didn't affect the result.

Fang Lin saw Wang Lu and Jin Zhu leaning over, and knew that they were about to leave, so he hurriedly responded: "Okay, then I'm leaving." ”

Ye Yuan, who got Fang Lin's reply, was really a little excited to be honest, and had to admit that Hua Guo had brainwashed children since he was a child, "Learn mathematics, physics and chemistry well, and you will not be afraid to go all over the world", there is really a certain degree of correctness in this world, and when he thought about alchemy before, Ye Yuan did not associate it with chemistry to make it easy to understand.

However, excitement is excited, Ye Yuan's attention is still on the news jade slip, Xuan Li really felt that the invisible line is a little thicker, then it means that Ye Yuan's judgment is right, he is indeed in the north of the camp, and now that Fang Lin and the others are moving north, the connection with the news jade slip will naturally be strengthened.

"Brother Liu, a hundred steps!" It didn't take long for Fang Lin's news to come from the news jade slip, fortunately, Fang Lin passed the news through Xuan Li, which would not attract much attention from others, after all, many people paid attention to the news jade slip.

"Received!" Ye Yuan replied, this was just the beginning, and the change in the invisible line was not enough to support Ye Yuan's judgment.

......

"Brother Liu, five hundred steps!"

......

"Brother Liu, a thousand steps!"

......

"Wait, Brother Fang, how many steps are there now!" Fang Lin passed a message to Ye Yuan in a timely manner every hundred steps, and just when Fang Lin didn't know when it was a head, Ye Yuan took the initiative to ask for the number of steps for the first time.

"One thousand two hundred and thirty-five steps!" Fang Lin was stunned for a moment and hurriedly replied.

"Thank you, Brother Fang, continue to tell me every hundred steps, it's really helpful!" Ye Yuan said with great joy.

Just now, the invisible line between the jade and the slip was actually weakened a little, which means that from the north-south direction, Fang Lin has surpassed himself, three hundred steps is one mile, then the distance between Ye Yuan and the camp in the north-south direction is probably close to four miles.

Three points can determine a plane, a direction map has appeared in Ye Yuan's mind, with Fang Lin's current location as the center, the camp is about four miles south of Fang Lin, and Ye Yuan is in the direction of Fang Lin's west or east, but it doesn't matter, what Ye Yuan has to do now is to follow the previous route.

Ye Yuan's previous direction was close to the direction of the camp, so it was either southwest or southeast, and as long as Ye Yuan continued to advance, he would inevitably be able to go to the straight line formed by Fang Lin and the camp, and after reaching the straight line formed by the two, as long as he chose to go due north, he could catch up with Shang Lin and the others, but he could catch up under the ground, and if he went south, he could come to the underground where the camp was located.

If you encounter a fork in the middle and keep the direction of travel unchanged, only consider going south or north, and resolutely do not consider going backwards in the east-west direction and turning back at the next fork in the road.

And in the north-south direction, the priority is naturally the north, only by going to the north can we maintain the connection with Fang Lin, if we go south, the connection with Fang Lin will be broken, Ye Yuan will fall into a situation where his eyes are black again, besides, Ye Yuan has a trace of speculation about why there is an underground passage in this underground.

......

"Brother Liu, 1,500 steps!"

......

"Brother Liu, 1,800 steps!"

......

With Fang Lin constantly providing information, the orientation map in Ye Yuan's mind became clearer and clearer, and he had gradually felt that Fang Lin and the camp formed a straight line, but because Fang Lin and Ye Yuan were both moving now, and Ye Yuan didn't know whether he was specifically east or west, it was difficult to determine whether the three were in a straight line in the north-south direction by simply relying on the change of the line, but there was definitely nothing wrong in the general direction.

"Brother Liu, the Impermanence Ziyue Ape is a mile away!" Just when Ye Yuan kept groping, Fang Lin came with different news.

One mile away, the last news came over was two thousand eight hundred miles, the location map was already completely clear, the impermanence Ziyue ape was about ten miles north of the camp, Ye Yuan now had to move closer to the north until he reached the ground below the impermanence Ziyue ape.

Having made up his mind, Ye Yuan showed a hint of a smile and moved forward non-stop......
