After the class, Zhong Hua took advantage of the thoughtful moment and approached everyone and asked privately: "There is still something that the official is confused about. Why does this zero point need to be called Ziwu? And why does it stand in the Taiji Temple in the palace?" His eyes were eager to learn and blinked. The drawing masters who were about to do their own things or were packing their notes stopped their work and their eyes were all gathered on this young master.

I really want to scold him for being troublesome. I am not a British man or a geologist. The books I teach do not have the name explanation of this broken thing. It's really, alas, I've come up with a trick!

"The meridian..." The eyes turned, and a simple cough was heard: "As for why Fang used the name "Benchu ​​meridian" to call the zero-degree line, it is actually very simple. The two words "Benchu" all mean origin, meaning the meridian, and extend outward from here. Every day, there are twelve hours, the min hour to yin, and the noon hour to yang, which means the alternation of yin and yang, and the intersection of latitude and latitude, I don't know if this explanation can be taken." As for whether the earth is square or round, well, we don't have the ability to let these old guys who are deeply poisoned by feudal thoughts immediately, anyway, let them know that the longitude and latitude lines must be crossed at right angles of 90 degrees. If one day our Tang Dynasty fought all over the world, it would not be too late to deal with these small problems slowly.

It’s nothing to do with this young master. We don’t want to be the Tang Dynasty version of Galileo. If Mr. Fang, the firm defender of feudalism and Taoist thought at home, knows it. If he doesn’t regard me as a psychopath, a young man who travels through time, tied me up and threw it into firewood and burned it into charcoal foam to eliminate harm for the country and the people.

Dozens of heads moved up and down in unison. Well, one problem was solved, and the other one. "As for why it stood in the Tai Chi Hall in the palace, this is located on the central axis of my imperial capital Chang'an, and it is also located in the center of the palace. It is where Your Majesty holds a court meeting. Let's talk about it, if you don't settle the zero point here, where can you settle?" He asked back to Zhong Hua, and asked back, "Swish, dozens of heads shaking quickly. Who dares to say that they are uneasy? It's for the Tang Dynasty. Hehehe, we don't need to say it explicitly.

"It's wonderful. My young master is indeed worthy of my famous scholar in the Tang Dynasty. All the words he said are counted. Zhong Hua is really, thank you for your teachings..." Zhong Hua's expression and eyes seemed to be so admiring. Well, very good. Today, I praised my name again. I don't know whether the explanation of Benchu ​​Meridian means this. The problem is that we can fool others and think that what I say is the truth. This is the ability. Hehehe...

I bid farewell to the doctor of the Ministry of Works and an official. I just left the imperial city and remembered a major event. I headed straight to the east city. Soon after, I arrived at the door of the last store.

"Shopkeeper is here?" As soon as I entered the door, I saw two young men greeting customers, and pulled a young man and asked.

"What's wrong with the young master looking for our shopkeeper?"

"Oh, tell him that the customer who made crystals with him last time has arrived." He smiled at the young man. Soon, the old shopkeeper who I mistakenly thought to be a time traveler last time walked out of the back room with a box. When he saw me, he quickly greeted me: "Oh, this young man, I have been waiting for you for many days, and this object has been ground up long ago." He happily handed the box to me like a treasure: "This thing is guaranteed to be as smooth as jade, crystal clear as the moon, and shine..." He boasted vigorously.

"Yeah, very good..." I responded randomly and opened the wooden box, a large convex lens piece about three inches square, and there were four pieces on the edge, two concave, two convex, and crystal pieces of different sizes. They were all lying crystal clear and crystals on the bottom of the wooden box made of red silk. I was a little excited, and reached out my hand tremblingly and carefully picked up the large piece. It was good, very good, without any impurities and cracks, the surface was smooth, without any roughness, and I took it and took it. It was very good, and my pores were instantly enlarged and appeared in front of me. It was done! Hehehe...-

I didn't want the old guy who was wandering around in front of me to see the purpose. After only looking at the transparency and clarity, I put the lid on the box and paid the money. When the old shopkeeper squinted his eyes and counted the money, I continued to ask: "Shopkeeper, there are crystals with color? They must be pure color transparent, and there is no impurity..." I really wanted to make a pair of sunglasses, and that thing was the most comfortable to wear in the sun.

"This is probably very expensive. Generally, crystals are considered high-quality products like the ones in the hands of young masters. If there are any mixed colors, it is difficult to pick one in a thousand..." The old shopkeeper narrowed his eyes and thought for a long time before he said.

"Oh, forget it, the shopkeeper's farewell, if there is a need, I will disturb you again." He hurriedly said goodbye to the jewelry store owner, and walked into a tavern in the east city with a happy mood. After filling his stomach, he returned to the Jinzouyuan and shook his head. He then pulled several heads together, and made guiding speeches on further perfection and subdividing the types of spies. Then he diligently conceived the charter for forming the military academy for a while. When he raised his eyes, it was already dim and it was almost the hour of You.

I put down my pen and stretched my waist. Well, we should go and meet the Tubo star. As soon as I entered the Zuyuan, I saw Fang Cheng standing opposite him with a knife on his waist and holding a horse. "Huh? Why are you here?" Today, because of office affairs, Fang Cheng stayed at home.

"I have met the second young master. The young master was ordered by the young master's young lady and came to Wangjiang Tower with the young master. The young lady also asked the young master to explain to the young master and listen to the few words." The loyal servant immediately led his horse and said to me.

"Little Madam? Oh, why is this girl so worried?" She said this, and her heart was warm. The palace maid's worries seemed to have her reasons. She was afraid that I wouldn't care, so she specially condemned Fang Cheng. First, she must be reminding me of what she told me today, and second, there was someone to accompany me, if I got drunk, someone would take me home.

"Then let's go." He took the BMW led by the doorman and stepped up, lifted the reins of the horse, and made a long neighing sound, flying four hooves towards Qujiang, the southeastern corner of Chang'an City...

The horse stepped on the slow road beside the Qujiang River, flowers were surrounded by flowers, butterflies whose wings were reflected by the sunset were dancing among the flowers, as if they were about to ride the last ray of sunshine. After their dance, the weeping willows swayed lightly, and the breeze swayed, and the smoke and water and the sunset were spread out. It was bright outside, and the fisherman's singing in the distance had not yet dissipated, and the sound of water on the nearshore had already responded. "Good scenery!" I couldn't help but sigh. Although it was not a small bridge and flowing water house, it had a unique ancient style of smoke and water Chang'an.

"Well, the water is good!" Fang Cheng couldn't think of an adjective for a long time, and after a long time he put it into two words, he also pointed out the beauty of Qujiang, all in the shattered golden blue waves.

"Let's go, it's not good to be late." I said this, but in my heart I hope that the Tubo is too stingy. If I can choose a good location and drink with the waves, it will be a good thing. I am here to have fun and see the beauty today, not to chat with you, an old guy. I hope this Tubo old man understands this truth.

The three-story wooden structure of Wangjiang Tower stands on the banks of Qujiang River. Among the buildings of one or two floors, it looks very prominent. When I got off the horse in front of the door, a friend came up to me and accompanied me to make trouble with my smile. "Young Master Fang, the old man on the third floor has been waiting for you for a long time."

"Huh? How do you know my surname is Fang?" I couldn't help but ask curiously, turning my head to look at Fang Cheng, and Fang Cheng was also confused. At this moment, accompanied by a loud laugh, Lu Dongzan, who had been dressed as a Han Chinese dress, walked out of the door and bowed: "Haha, Mr. Fang, the eldest son, has not arrived for a long time. When he looked around, he saw a gentleman in white clothes standing by the bank of Qujiang. Although Dongzan had not identified his face, he knew that he must be Mr. Fang, otherwise, who else could have such a charm? He specially called the friend to come down and wait first."

"I am really ashamed. I'm busy with official business, so Lord Lu has been waiting for a long time." The old man praised me and blushed. He quickly returned the gift and walked into the door. When he arrived at Qujiang Tower, he realized that it was quite large. Four three-story buildings were surrounded by an excellent pavilion in the middle. The lights were bright, and with the last ray of skylight, the fat leaves and light flowers were even more confused.

"Lord Lu can choose a place." He sighed very much. He really missed Li Ke, the brother who killed chicken heads and burned yellow paper. I don't know when this guy would pretend to be sick and crawl back to Chang'an to meet my brother. I haven't seen him for many days, so I wondered about this kind of brother who always stolen his swords at his friend.

"Where is it? I changed into Hanfu today, just to follow the customs. In order to invite the young master, I spent a lot of effort to ask the servants to inquire about it. In this spring, the shadow of Qujiang in Chang'an City can be regarded as this!" Tubo gave a thumbs up and squeezed at me proudly.

"Oh? I'm so lucky. Lord Lu treats me like this, so he's so flattered..." He responded, and he felt in his heart that this old man was afraid that he had something to do.
