Things don''t know numbers. It''s a famous mathematical problem in ancient times. I didn''t expect to see it here.
Xie Tianji looked at Yang Xuan lightly, and his eyes were full of contempt.
Yang Xuan smiled and said directly, "Twenty three."
The smile on Xie Tianji''s face solidified. He looked at Yang Xuan strangely and showed a touch of surprise in his eyes. However, the surprise was fleeting. He opened his mouth and just wanted to say something, but Yang Xuan directly interrupted him.
"128."
The expression on Xie Tianji''s face solidified again, and what he wanted to say was also held back in his throat.
Yang Xuan almost didn''t give him a breath, and then said, "233, 338..."
Xie Tianji froze. After a long time, he looked at Yang Xuan and asked, "there are 233? There are 338."
Yang Xuan smiled and said, "there are 443 more."
Xie Tianji didn''t speak. He suddenly squatted down and checked quickly on the ground. After a long time, he got up and stared at Yang Xuan in a daze. He asked, "how did you calculate so fast?"
Yang Xuan laughed to himself. The problem of not knowing the number of things was a classic in his previous life. How could he not know that? Now he just follows the book.
When Wudao saw Xie Tianji, he looked shocked. Knowing the results in his heart, he couldn''t help laughing and said, "thank you, Mr. Ren is quite accomplished in mathematics. Now you believe it."
Xie Tianji still looked at Yang Xuan in disbelief and didn''t answer his words.
After a while, he suddenly said, "I want this man."
After talking, he directly grabbed Yang Xuan''s arm and pulled it away.
Yang Xuan earned a little, and his eyes had looked at Xie Tianji. Then he glanced at Meng Qingqing.
Xie Tianji was stunned. Then he understood what he meant and said anxiously, "let''s go, let''s go together.
While making Wudao shake his head and smile bitterly, Xie Tianji has taken Yang Xuan and Meng Qingqing away without a trace.
There was only one person left in the hall. After meditating for a moment, he said faintly: "bury the body of Hao Zun and compensate his family with double standards. This is the end of the matter. No one should mention it again."
Someone outside the door gently promised and turned away.
A smile slowly climbed up on the Taoist face, which means inexplicable.
Led by Xie Tianji and passing through countless strange buildings, they entered a huge cave.
After passing through several heavily guarded doors, Yang Xuan was directly shocked by the scene in front of him.
In front of him, there was a huge space. On the ground, it was made of bluestone. On the huge table, there were countless bottles and cans, about half of which were carved from crystal.
Yang Xuan could hardly believe his eyes.
Where is this cave? This is a huge laboratory.
On the table, there should be test tubes and flasks carved from the whole crystal, all showing Yang Xuanzhao a breath of science.
At this time, Yang Xuan was shocked. Unexpectedly, Xie Tianji not only studied mathematics, but also chemistry, but also looked at other tools placed aside. Maybe he could also make achievements in physics.
This is an ancient scientist!
Xie Tianji looked at Yang Xuan proudly. The peasant expression on Yang Xuan''s face like Grandma Liu entering the Grand View Garden made him very comfortable.
"Brother Ren, although you are not as good as me in numeracy, I admire you for putting forward the method of shadow measurement." Xie Tianji looked at Yang Xuan proudly: "but you don''t understand the things in the cave."
He has changed his mouth and called Yang Xuan brother Ren, which can be regarded as recognition of his attainments in mathematics.
Xie Tianji went over, picked up a test tube and sighed, "don''t say you. It''s estimated that no one in this world will know what I''m doing. I''m lonely."
Said, he made a pair of Invincible is how lonely appearance, very smelly fart.
Meng Qingqing couldn''t stop looking around. In this huge cave, there were more than a dozen biyunzong disciples in uniform. He didn''t know what he was busy with.
Yang Xuan approached the stone table and picked up a crystal bottle with a label and a symbol that Yang Xuan didn''t know. There was white powder in the bottle. I don''t know what it was.
"Don''t move, you can''t afford to break it." a middle-aged man came over and looked at Yang Xuan unswervingly.
Yang Xuan smiled, put down the crystal bottle again and didn''t speak.
Chemistry?
Sorry, he happens to be a chemistry major.
If you take out a little chemical knowledge in his brain, it''s light to hang and beat Xie Tianji. It''s estimated that he can''t be found in this world.
At this time, he had an idea in his mind that Biyun sect was famous for using poison. Could it be that all the poisons of Biyun sect came from here?
Then he shook his head again and denied the idea in his heart.
The poison of biyunzong has long been introduced into the Tao with poison, and its effect is not achievable by chemicals at all.
Obviously, Xie Tianji brought him here not to study chemistry, but to learn mathematics together.
Xie Tian turned and took out a piece of paper, spread it on the empty stone table, waved to Yang Xuan and said, "brother Ren, come and see this. What do you think?"
When Yang Xuan heard the speech, he walked over and swept his eyes on the paper.
What is painted on this paper is a three-dimensional figure, which is a bit like a flask. Below is a ball, on which stands a cylindrical object.
Seeing this, Yang Xuan suddenly moved in his heart.
Do you know the length by shadow measurement, and the side circumference is straight?
If the things on the picture are infinitely enlarged to such an extent that it is impossible for a person to measure the specific value, then the two methods he said can be used.
Yang xuanminrui felt that he seemed to have come into contact with some secret.
Xie Tianji looked at Yang Xuan and observed his expression.
Yang Xuan directly asked, "thank you, what is this?"
Xie Tianji hesitated for a moment and didn''t directly answer Yang Xuan. Instead, he asked, "if this object, um, this thing is so huge that manpower can''t measure its height, can you know its height with the shadow measurement method you said?"
Yang Xuan looked at him and said tentatively, "a warrior can fly. Can''t he measure his height?"
Xie Tianji shook his head and said, "that place can''t..." before he finished, he seemed to realize that he slipped his tongue. Gu left and right said, "in short, human power can''t be measured."
Yang Xuan moved in his heart and thought, "if there is a constant light source, which can make this object produce shadow, we can get the specific height."
Xie Tianji pondered, "how to calculate it? Can you explain one or two, brother?"
Yang Xuan looked at him speechless. Didn''t you look down on people just now?
However, he has realized that Xie Tianji''s respected status in Biyun sect may still be beyond the Tao. With his words, can he and Meng Qingqing be safe?
At the thought of this, he didn''t beat around the Bush and directly said to Xie Tianji, "thank you, to be honest, I''m both prisoners at the moment..."
Before he finished, Xie Tianji waved his hand and said, "no matter what you have done, I will keep you two safe. You can rest assured."
This is domineering, but Yang Xuan still said, "old Xie doesn''t know. I''ve killed a venerable person of your sect..."
Xie Tianji said impatiently, "as long as you don''t kill a few people with names on them, others don''t matter."
Domineering!
Yang Xuan gave him a thumbs up in the dark.
Meng Qingqing also looked at Xie Tianji with great interest.
Yang Xuan was relieved. With Xie Tianji''s words, Biyun sect must not be embarrassed by anyone again.
At this time, Ling Wudao suddenly came in. He looked at Meng Qingqing and said, "let''s go. The old man Meng of your family took me to send an elder to replace you."
Yang Xuan was stunned. Didn''t he change it? Why did you change your mind again?
