As soon as this speculation surged in her heart, Su Yi didn't dare to hold it up, and saluted respectfully: "What advice does the old gentleman have?"

The old man smiled indifferently and said in a very slow voice: "Your mental power was originally not enough to start a strategic game, but this embattled Star Picking Pavilion still teleported you to a fantasy realm by mistake, can you tell me: What did you meet in the illusion and what did you get?"

Su Yi broke out in a cold sweat behind his back, to be honest, he himself felt that it was strange to be teleported to his former alma mater, and sure enough, someone came out to question him at this moment. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Regarding his identity and background, Su Yi felt that it was better not to expose it, but since the old man would ask questions, he said that if Su Yi lied, he might not be able to hide it from his eyes.

When he was in trouble, Su Yi had an idea and said: "Don't tell the old gentleman that in this illusion, Xiaosheng returned to the academy where he once studied, and met some old classmates; ”

Su Yi used a very ingenious fuzzy method to blur the general environment of the illusion, and only pointed out a few key words: academy, classmates, and books, not only telling his true experience, but also not violating the harmony at all in the Bingfeng Continent;

"I see, with the scenery of my hometown, it makes people feel homesick, which is quite in line with the test content of embattled. Little friend, the only way to pass the embattled test is to cut off your nostalgia for your hometown, otherwise this wrong illusion will make you lose in it forever, but you cut it off?"

"After returning to his hometown, the nostalgia in Xiaosheng's heart gradually faded. Su Yi replied honestly.

The old man nodded, as if he agreed with Su Yi's explanation, and did not intend to ask again.

Su Yi secretly breathed a sigh of relief and said, "The trial has failed, can Xiaosheng leave?"

"Failed the trial?" the old man raised his eyebrows, and there was an inexplicable meaning in his smile, "Who said you failed the trial?"

"Xiao Sheng's spiritual power has been exhausted, and he can no longer afford to start the next strategic game, isn't this considered a failure?" Su Yi wondered.

"Little friend, this year's test is several times more difficult than usual, with your talent, in previous years, you can win at least three general stars. The old man laughed.

Su Yi said in her heart, and asked cautiously, "Why is this year's test suddenly more difficult?"

"You're too low in rank right now, and knowing too much will distract you, so I'm not going to tell you too much. The old man said solemnly, "You just need to know that it is for the sake of the whole human race to make the test of the Star Picking Pavilion difficult." ”

"Understood, Xiao Sheng didn't ask much. ”

"As I said before, you have extraordinary talents, I can't bear your talent to be buried by this coincidence, as long as you answer my question, I will give you a creation. The old man smiled encouragingly.

"Please give me advice, old gentleman. Su Yi said.

"I'll only test you in astronomy. We can see the moon when we raise our eyes at night, and you must have noticed that the moon is round or absent, not fixed in a circle like the sun, and some people say that it is eaten by tengus, what do you think is the reason for this?" asked the old man.

The corners of Su Yi's mouth twitched, remembering that the astronomical theory of the Bingfeng Continent was not so developed, and it was still at the stage of the Heavenly Theory, and only those who were in high positions could get a glimpse of the whole world. Su Yi naturally has a complete set of astronomical theories, but as a martial artist, it would be strange if he had extraordinary knowledge.

"Old sir, your question is too tricky, I'm just a martial artist......"

"It doesn't matter, the sun, moon and stars can be seen by raising their eyes, and even if they don't have knowledge, they will have some imagination, even if they can say your hypothesis. ”

"Okay. Su Yi thought about it briefly and said: "Because we will produce shadows when we stand under the sun, I guess that the so-called lunar eclipse phenomenon is actually the shadow produced by the sun shining on the continent when the moon circles behind the Bingfeng Continent." ”

"Oh, your opinion is more unique than ordinary people, do you want to say that the moon can only be seen by us when it is illuminated by the sun, and that the moon itself cannot shine?"

"Yes, the moon is simply just a big spherical stone, how can a stone shine?" Su Yi said briefly.

"Do you have any evidence for that?"

"I can't prove these things by a martial artist, but I've heard that when I was a samurai, I was able to learn the side ability of 'the end of the world', turning the end of the world into a few corners, distinguishing things for thousands of miles, and I should be able to vaguely see that there is no water or trees on the surface of the moon, and it is all stones. Su Yi replied, scolding in her heart, "Actually, this ability is a telescope, and I heard that there are other wonderful uses." ”

"The proximity of the samurai can indeed make people see farther, but only when you advance to the rank of a hero can you clearly see the surface of the moon. The old man said with a smile.

"Then I can only ask Haojie to prove it for me. ”

The old man smiled and asked, "According to what you said earlier, that lunar eclipse is a projection of the Bingfeng Continent being illuminated by the sun, why does that projection not reflect the mountains and rivers of the continent, but an arc?"

"Because the Bingfeng Continent is the same as the moon and the sun, it is a big ball. Su Yi replied immediately.

"How?"

"When I was younger, I climbed mountains with my classmates, and when I climbed high mountains, I saw that the ground in the distance was round. Su Yi replied.

"It's not enough to prove that maybe the ground is inherently undulating. The old man shook his head.

"The ground is undulating, the water is not. Su Yi said, "The Terran and Yingzhou have frequent exchanges, and you can often see the ships that go to sea gradually disappear, and when they come back, they always come out of the mast first, and then the hull appears, which can also prove that the Bingfeng Continent is spherical." ”

"Maybe it's just an arch?" said the old man with a tentative smile.

"I saw in the book that there was once a prince who loved to travel in Yingzhou in the East China Sea, and he drove the Qilin horse convoy to the east and never changed his direction, but a few months later, he came to the west coast of the Bingfeng Continent, can it be proved that the continent is spherical?"

The old man nodded, and with a wave of his hand, a three-foot-diameter water-blue sphere appeared in front of Su Yi, on which lay the entire territory of the Bingfeng Continent, similar to the earth in space.

"Is this what the Bingfeng Continent in your heart looks like?" the old man asked.

Su Yi was amazed by the old man's ability to create things at will, and nodded, "Exactly." ”

The old man shook his head and accused: "If the Bingfeng Continent is like this, and people stand on it, won't they fall down?"

Su Yi thought to herself, if she wanted to answer this question, she would have to mention the advanced concepts of continental rotation and gravitation, which would definitely be endless, so she said briefly: "Because there is a huge suction force inside the Bingfeng Continent, which can absorb everything on the sphere, no matter where people stand on this sphere, they can walk on the ground as if they were on the ground, and there will be no danger of falling down." ”

"I see, to summarize what you said earlier, the relationship between the sun, the moon, and the Bingfeng Continent is like this. ”

The old man waved his hand again, and two small spheres, one gold and one silver, appeared on the side of the Bingfeng Continent, which were moving around the equatorial line of the continent.

Su Yi shook his head and said, "The moon does move around the continent, but the sun is a million times larger than the continent, and the continent moves around the sun. ”

"Oh, do you think this is the relationship between the three?" the old man waved his hand again, and the sun suddenly became as large as the original continental sphere, but the continent was rapidly shrinking, becoming smaller than the little finger, and was moving around the sun, and the moon orbiting the continent had become the size of a grain of rice, almost invisible.

"That's right. Su Yi nodded.

"The sun is so big, isn't it going to break the sky?"

"The sky is endless, and the sun is just a small gravel in the desert, a drop of water in the vast sea. Su Yi replied, in fact, the sky is the universe.

"According to what you say, the ancient Gaitian theory and the Hun Tian theory are wrong?"

"These are just scenarios imagined in the minds of the little students. Su Yi said cautiously, never talking too much.

The old man nodded and said, "Your hypothesis is very original, and I will use your statement as a reference to improve the theory of astronomy." ”

"Then have I already answered the questions of my predecessors?" asked Su Yi.

"Naturally. The old man smiled and nodded, "Just ask here now, and I'll reappear when you get promoted to pedestrian and come here again." ”

Hearing this, Su Yi's heart sank, and she thought that she must prepare a complete astronomical theory before pedestrians.

Then, the old man pointed his finger, and Su Yi's mind, which was originally as light as clear water, actually gushed out a trace of fluorescence, and then his body left the ground and slowly floated up.

Su Yi saw the old man's figure disappear farther and farther away, and his mind passed through the wall of the pavilion and came to the sky above the top of the mountain.

"Hey, that's Su Shicai?" A sharp-eyed person immediately spotted Su Yi hanging in mid-air.

"Really, why didn't he come out of the front door?"

Everyone raised their eyes, and everyone looked puzzled, not knowing why Su Yi was suspended in the air.

Su Yi is still rising.

Countless scenes flashed in Su Yi's eyes, he saw the mountain tops and pavilions slowly shrinking, and saw the twenty-eight peaks under his feet in the sea of fog like small stars embedded in the night sky, and the figures of all the scholars gradually disappeared in Su Yi's eyes, leaving only the vast sea of fog filling his vision, unable to see the whole picture of the armillary disk under his feet.

When he rose to an estimated height of 2,000 zhang, a burst of bright light suddenly stung Su Yi's eyes!

"Hmm, this is ......" Su Yi had to close his eyes, at this moment, he felt a pure energy washing his mind, making his mind regain solidity, and it became stronger and stronger, and there was no tendency to stop at all.

Su Yi was like the only sun in the sky, and the strong light that erupted obscured the night sky, and all the students who had not yet entered the Star Picking Pavilion all raised their heads to the sky, and when they saw the vision of the sky, their faces were surprised and trance-like.

Obviously, Su Yi was dozens of miles away from them, but the strange thing was that everyone could clearly see Su Yi's serene face in the strong light!

"It's Su Shichou!" someone shouted on the top of a certain mountain.

"It's really him! Why is he so high?"

"That's too high, how the hell did he get there?"

A disciple of the sect replied: "I heard from the seniors in the sect that the first place in the Star Pavilion will have a special encounter, could this be what you are referring to?"

"Su Shichou is naturally the first, but this is how the special encounter rises into the air and shines, what can you get?"
