"I don't understand very much." Xu Tianling said with his cheek, "That is to say, as soon as a person enters, everyone will suddenly forget his existence?"

"It's probably so." Emperor Nether was a little impatient, but when he faced Lao Tie, he still chose to speak out. "A living dead man came in and came out again. He said that he had not walked far after he entered and met some people. Those people were all weird and dangerous. He ran back because he was afraid, but after he came out, he found that the people he knew no longer existed, and we didn't know him. He is still looking for people he knew, but he can't find any of them, so he is called the Forgotten One."

Xu Tianling frowned slightly and looked at Zhou You and said, "The extreme quantum hypothesis can be explained barely, but I can't believe it."

"This is too evil." Zhou You looked at the map and said, "Since the information is isolated, how do you know that there are three realms?"

"Living people told us." Emperor Ming looked at the center of the map and pursed his lips. "There was a living person who came out, but he died as soon as he drew this picture. Living people could not live in the world of the living dead. In the past, there were living people or dead people who crossed the boundary river, but they all lost their minds. Only that living person, he retained his consciousness, but unfortunately he died..."

Emperor Dark waved his hand as he said, too lazy to say these things: "Anyway, in my territory, I can do anything for you, but I can't control the living and the dead."

"The plane of the living dead, the plane of the living dead..." Su Yiyi muttered, "It turns out that it refers to the plane of the living, the dead and the living dead..."

"Anyway, I actually have nothing to explore here, so there is a lot of time." Emperor Ming smiled and said, "If you have nothing to do, just play games, and occasionally flirt with girls."

"Don't you fight? Is there no dispute?" Zhou You looked at the outfit of Emperor Dark, and he should have done it if he didn't accept it every day.

"It turned out that there were too few people and too many lands, so I didn't want to fight anymore. Everyone wanted to fight me to be the emperor when I saw that I was a human being." The Emperor of the Underworld continued to smile, "Actually, I don't have to worry about anything. Generally, something can happen in a year. There are many people on both sides to fight. I gave me face before starting the fight and asked me to witness it. As I went to have a banquet, we would drink and talk while drinking. As we talked, we found that everyone was friends and old men, and then we broke up."

Zhou You's mind was full of middle school students who were confused by a disagreement: "You are not the emperor, you are the leader..."

"Hi, that's the same." Emperor Ming rubbed his hands and said, "Let's hurry up, you'll drink it all in full. Who can withstand the smell of Maotai?"

"Well, let's start." Zhou You nodded and said to Xu Tianling.

Xu Tianling quickly pulled out a round cake marked with a scale from the big backpack Zhou You brought. This was actually a cylinder made of several old optical discs. A layer of white paper was pasted on the top. The center, radius and scale were marked on the white paper, and the scale was also marked on the circumference, which was equivalent to engraving the measuring ruler on the disc, thus eliminating the measurement process.

Several people formed a circle and looked at the disc in Xu Tianling's hand. The scale on it did not change at all, accurately showing the relationship between diameter and circumference.

"Is this normal?" Su Yiyi asked.

"Well..." Zhou You stared at the disk and pursed his lips, "It looks normal, I always feel a little weird, I can't explain it clearly... Is this scale okay?"

Xu Tianling took out a hand-held rangefinder and a hardcover book from his backpack without saying a word, placed the disc on the ground, blocked the hardcover book vertically at the center of the circle, and used the rangefinder to re-measure the radius.

"When will I put this kind of thing in my bag?" Zhou You stared at the rangefinder and said in surprise, "Is this necessary?"

"If my guess is correct, I can't believe the ruler here." Xu Tianling pressed the button and saw the numbers on the rangefinder clearly, and smiled softly, "Shopkeeper, your intuition is also correct. The scale has been compressed and has failed. The real radius of the disc has become shorter."

Then, she took out an extremely thin thread and re-determines the circumference. Unlike the Yuling Plane, the disc here even has a shorter circumference.

After recalculating, the pi here is about 2.58.

"I am really... becoming more and more confused..." Zhou You was stunned as he looked at Xu Tianling's series of operations.

"I can tell you the guess." Xu Tianling happily put away a bunch of tools.

"I can't help it." Zhou You swallowed and spitted, "I'll give myself some more time."

Emperor Ming looked at Zhou You's serious appearance, and the more he looked, the more he became funny: "You are so leisurely."

"Yes, right!" Willon jumped up and looked at the Emperor of Underworld with gratitude, "I finally met a normal person."

"Hahaha, why bother with great grudges?" Emperor Dark Sleeping and Wanton laughed, "It would be better if Xiao Wangle is poor."

"Oh, yes! Can I stay here to play with Uncle Emperor, store manager?"

Zhou You couldn't imagine what kind of sparks these two people would create together, and whether their IQ would gradually collapse when interacting.

However, Emperor of the Underworld is an adult after all, so how can a child take the words seriously?

In order to take care of Zhou You's emotions, he quickly patted Wanton's head and said, "Don't think Zhou You has a lot of trouble. We also have people who like to explore. They are usually smarter. They have also measured pi and other things, but they gave up quickly and came to me to play double dragon slit."

"Why did you give up?" Xu Tianling asked hurriedly.

"Wait." Emperor Ming looked at Xu Tianling with a smile, "3-2-1. Okay, you can test again."

“What to test?”

“Pi.”

"It's been measured."

"Test again." Emperor Nether giggled, "Try it, try it."

Such a big man with armor suddenly felt an inexplicable horror when he smiled like this.

Xu Tianling was a little difficult to understand the words of Emperor Ming, but she repeated the measurement process again.

A strange thing happened, the radius and circumference changed slightly, and the pi changed from 2.58 to 2.56.

"Are you sure?" Zhou You also lay on the ground, "Is it an error? Is this rangefinder reliable?"

"It's not wrong." Xu Tianling said gasping, "I measured each set of pi three times."

"Hahahaha." Emperor Underworld laughed, "It will change, these will change. Do you know whether it will become bigger or smaller, so I can't understand it at all. Lao Tie, what are you doing? Why study a number that does not exist at all? Let's start drinking!"
