"Okay, we've now confirmed that we've encountered a ghost hitting the wall, so how are we going to get out?" Yao Yilan didn't seem to know how terrible the ghost was hitting the wall.

Ming Miaohui knew, but she didn't speak, but was silent and clenched the hand of the apprentice Yao Yilan.

Tang Ding was not afraid, he had a strange feeling. This feeling is still familiar, it is at the bottom of the Tianchi, inside the big bronze gate, where the Hidden Immortal Sect is located, it is also a dark environment, but there is a little difference, in the location of the Hidden Immortal Sect, there is also a light that penetrates the darkness and indicates the direction of progress, but here, it is pitch black and dim.

"Don Ding, why don't you speak? How do you think we can get out?"

"Get out? First of all, we have to break down the wall of this ghost, and then we can talk about going out. ”

"Then how can you break the ghost wall?"

Tang Ding didn't answer, because he couldn't help it.

But what Tang Ding thought was, if he couldn't get out, would he die here? There was no food here, no water, oh no, not no water, but seawater.

By the way, now you should find out where the sea water is for the three of you.

Although drinking too much seawater will make people thirstier and thirstier the more they drink, with Tang Ding's cultivation, he can selectively absorb seawater and separate the salt in seawater.

However, this sea water seems to be getting farther and farther away from him, because he has just walked a lot of circles here, and he has never seen the shadow of sea water at all, and the sea water he fell into is nowhere to be found.

It is still necessary to break the ghost wall first.

"By the way, you said earlier that you were worried, you weren't worried about ghosts hitting the wall, what were you worried about?" Yao Yilan suddenly remembered Tang Ding's words before.

"My biggest concern is not that the ghost hits the wall, at least the ghost still has traces. ”

"And what are you worried about?"

"Maybe it's the uncertainty that I can't control my own destiny!" Tang Ding didn't say all the worries in his heart.

First of all, Tang Ding has to find a way to crack this ghost wall.

It stands to reason that if this kind of ghost hitting the wall is artificial, at least there are traces to follow. Because the man-made ghost hitting the wall is carefully calculated, including every corner, every distance, there are precise calculations. And this place is obviously not thought to be formed, because there is no trace of man-made here, besides, in the era of Xuanwu, is there anyone who still says it? Even if there are people, I am afraid it is difficult to compare with Xuanwu.

Then there is only one possibility, the ghost hitting the wall here is a natural formation. The formation of ghost walls in nature is very harsh, although there is no human precision calculation, but there must be a method, this method makes all calculations belong to one point.

This method is like a formula, so that all the calculations can be summed up in a result.

Dondin's brain was running at high speed, analyzing all the possibilities of the ghost hitting the wall.

If it is really a ghost that is doing something, then Tang Ding will be very happy, because ghosts are a kind of qi, and Tang Ding may need to consider other things, but when it comes to qi, Tang Ding is nine out of ten.

However, there seems to be no qi here, or the ghost hitting the wall here does not have the effect of qi. As for whether this Xuanwu and the Seven Stars are angry or not, this Tang Ding is hard to say, even if there is qi, it should be after breaking the ghost wall.

This ghost hitting the wall should be a test of yourself.

Tang Ding had a hunch that if the ghost hit the wall, the road to the dead tripe cave would be presented.

But how do you break the ghost wall?

Don Ding still needs to give it a try.

This time, Tang Ding did not walk 2,000 steps, but walked 1,000 no, and then turned back ninety degrees, he wanted to see if he could return to the origin of the oxygen cylinder this time.

Sure enough, as Tang Ding expected, Tang Ding returned to the original point again after turning back. Of course, this time it wasn't exactly a thousand steps, and after he had walked a thousand steps back, he saw the oxygen cylinder again, but it was forty meters away.

Like the previous time, Tang Ding walked 2,000 steps, and after turning back 90 degrees, he returned to the original point, but that time he was more than 80 steps behind. This time he walked a thousand steps, then turned back, and after a thousand steps, he was forty meters from the point of origin.

Is it a coincidence that the previous 80 meters and the current 40 meters are a coincidence?

Don Ding didn't think it was a coincidence.

With Tang Ding's cultivation, every step he took seemed to have been measured, and one step was sixty centimeters, of course, Tang Ding's two steps were for good calculation, and the big step he just took was controlled at one meter.

The meter that Tang Ding walked was exactly one meter, and there was no difference at all, not to mention walking two thousand steps, that is, walking one hundred thousand steps, he could still control his cadence was absolutely the same, and the length of each step was absolutely equal.

Even under such accurate calculations, there is still a difference of tens of meters, which is impossible, there must be something wrong.

Tang Ding stood still, meditating.

"Tang Ding, what are you going to do?" Yao Yilan saw Tang Ding suddenly move, and hurried into the distance.

"You wait here for me, I'll try again. ”

"Don't we have to follow you?"

"No, I'll go and go back. "Tang Ding walked a hundred meters this time, and then turned back ninety degrees, but this time his error was even smaller, only less than ten steps.

The distance is large, the error is large, the distance is small, and the error is small? Tang Ding has found this law, but it is a little unclear.

"Tang Ding, you must have discovered something, tell me quickly, let's analyze and analyze together. ”

"Okay, listen. Tang Ding just couldn't make up his mind, he wanted to hear the analysis of Yao Yilan, a beautiful scholar.

Tang Ding told Yao Yilan about the data of his experiment just now.

Although Yao Yilan followed Ming Miaohui to become a Taoist priest, her agile mind was still there, and she thought about it, "This seems to be very simple, any kind of situation will return to the original point, which can only mean that this origin is the only one." And the only origin has a feature, it's in the middle of the whole field, and the surrounding area is equidistant, oh, I'm a little complicated to say that, to put it simply, I think it's a cone. It's just a cone with a very small slope, a cone that we don't feel the slope at all, but the slope is real. ”

After listening to Yao Yilan's words, Tang Ding couldn't help but admit that Yao Yilan was really talented. After thinking about it for a long time, she only told Yao Yilan once, and she quickly judged the conclusion that she had been thinking about for a long time.

"Yes, I think so, and I think it's a cone, because only a cone can explain what we're going through. No matter how we go, we will end up at the apex of the cone, but how do you explain this error?"

"The error is not difficult to explain, because you are a ninety-degree turnback, and your turnback is equivalent to walking an arc, so you will walk out of such an error, and the farther you go, the greater the error. ”
