Ding Xiaobo recalled his first meeting with Gongsun Linglong, and couldn't help but have some longing for this meeting.
The last time they met, the two of them discussed the small hole image discovered by Mozi. Use wooden boards to block the gap between the torch and the wall. If a small hole is opened in the middle of the wooden board, an inverted torch image will appear on the wall.
According to Mohist understanding, the cause of the inverted image is that light propagates like a straight arrow. The light from the torch passes through the small hole, and the light from the upper part falls on the lower part of the wall.
Light travels in straight lines, which can explain the formation of shadows of objects under the irradiation of light that we usually see.
After this, many questions arise. The reason why people can "see" is because light shines into their eyes. When compared with the world, people's eyes should be like small holes. So why do people see things with their eyes not upside down?
of?
Also, only luminous things will have light emitted into the eyes and be seen by people. Under normal circumstances, only a few things such as torches will emit light. In theory, it is pitch black and nothing can be seen, which should be the normal state of human "seeing"
.
The difference between night and day is sunlight. All things themselves do not emit light. It is the sunlight that illuminates all things, so light shines from objects into the eyes, and only then can people see it.
Sunlight is a kind of light that shines on a stone, and people see the stone; it shines on the lake, and people see the lake. It is the same kind of light, so why is there such a difference? Is it because each object reflects different colors?
Light, and sunlight is the light that embodies all things.
Gongsun Linglong, Ding Xiaobo, and a group of old scholars from Qi Mo all believe that the essence of the world is material, and humans must take the initiative to explore. There must be material causes behind phenomena.
For example, light travels in straight lines. Currently, everyone believes that this is a definite law, but they also firmly believe that one day they will be able to find a material cause that explains this law.
The number of people studying the "Mo Jing" is getting smaller and smaller from generation to generation in the Mohist family, and it is extremely common to find no disciples to inherit the mantle. Martial arts are difficult to lose, but for these things, if a key figure dies, the inheritance will be cut off.
For the old scholars of Qi Mo, they were very happy to have a young boy named Ding Xiaobo who was particularly curious.
When they heard that Lu Yan, the master of the State of Qin, actually publicly declared that the world exists as an object, humans should be used as subjects and we should take the initiative to study the world of objects. There is no heaven or god. They were so excited that tears filled their eyes, and they were extremely regretful.
When another fellow disciple, Gongsun Linglong, appeared, and he was also a famous person, the so-called sectarian opinions were instantly forgotten by everyone.
Master Xu could see that Ding Xiaobo's expression seemed to be one of longing and joy. He couldn't help but twitch his white eyebrows, and was secretly shocked: Could it be that Xiaobo had fallen in love with Gongsun Linglong with his appearance?
"Master Xu, let's go."
Ding Xiaobo held the long whip and waved his hand.
"Oh, okay, let's set off,"
Master Xu shook his head, opened the curtain and sat in the carriage, still holding the Thunder Sword in his hand.
…
The Seven Evil Swords of Luowang defeated the Qilin Society headquarters and obtained a box that was suspected to contain important secrets. In order to open the Shiquan Jiazi lock on the box and publicize the enemy, Xu Fuzi rushed to Xianyang as soon as he received the message.
At the same time, Nong Yu and others from the Qilin Society also moved south as planned. Currently, Nong Yu himself and Songlong have gone to Songhai to meet Zhuan Sunxun, with the intention of discussing the alliance between the Qilin Society and several Confucian sects.
…
"This is Songhai City, the hometown of Little Saint Xianzhuang, and the place where my husband's former master was."
Nongyu stood on the edge of the street, looking casually at the bustling crowd, sighed, and walked slowly.
"I feel ashamed to say that this is my first time coming to Songhai."
Nongyu has never been to Little Saint Xian Manor, let alone met Xunzi in person. Now that he sets foot on this land, he feels a little complicated.
This can't be blamed on her. Lu Yan has only gone back once in the past twenty years since he left Xiaoshengxian Manor. At that time, he was accompanied by Ju Shuang. When he came back to Songhai, he met Xunzi for a crown ceremony, and then returned to Xianyang to propose marriage to Nongyu.
.
Songlong was always paying attention to the situation on the street and reminded: "Madam, we live in Qixia Residence, please come with me."
Nongyu followed him and praised at the same time: "Qixiaju, Qixia, a good name, very beautiful, with a feeling of desolation and loneliness."
"This name comes from brother Zidan. Madam's Qilin's word selection is equally exquisite. You two may be able to communicate later."
Nongyu was startled subconsciously. How could you openly say such dangerous things on the street? Then she realized that Songlong's words actually rang through her mind.
"Sir, could this be the secret technique of sound transmission?"
"Yes, it's the sound of nature transmitting sounds."
"The secret method of Taoism is really incredible."
"Haha, madam, I'm so impressed. Just because of this secret technique, most of the things I've done over the years running around and connecting with people have been done by me."
"Haha, that's really hard work, sir."
"I will enter Qixia Residence in a moment. Madam, please follow me closely. You don't need to talk to anyone."
"clear."
…
In the evening, Songlong led Nongyu into the backyard of the inn in Qixiaju. Their room was adjacent to an attic.
After confirming that no one was around, the two of them flashed to the top floor of the attic, and Songlong gently turned a wooden shaft of the window.
"I envy the old crow, I am used to living in the clouds, and the mayfly is born in the home of heaven and earth." A faint voice came from the room.
Song Long condensed his voice into a line and responded: "I have pity for the world, but I always have few people. I am born in spring and killed in autumn. I lower my eyes in winter and summer."
After matching the codes, he opened the door and asked Nong Yu to come in.
In the underground secret room, Nongyu looked at the dim candlelight and said to Songlong who was leading the way: "With such ingenuity and talent, Zhuan Sunxun really deserves his reputation."
"Mr. Songlong, you are back."
When Qin Jia saw Songlong, she immediately walked up to her excitedly and said, "Ah, this person is Mrs. Nongyu! I'm disrespectful."
Songlong had expected it, so he pressed Qin Jia's shoulders very naturally and said to Nong Yu: "Madam, let me introduce you. This is Mr. Zhuansun's junior brother, named Qin Jia."
"It turns out he is Mr. Qin Jia from the Zizhang sect. He is very polite when it comes to jade."
Qin Jia saw Nong Yu cupping her hands in salute, and immediately waved her hands in panic, "No, no, no, no, I really can't bear the word sir. When the senior brother comes back, madam, you can tell him again."
His reaction made Nong Yu couldn't help laughing, and she covered her mouth slightly.
I had always heard in the past that the Zhang sect of Confucianism did not pay much attention to etiquette and rules, and that its disciples were often outspoken and free-spirited, and some even had a dissolute attitude. Now it seems that the rumors are actually true.
Songlong gave priority to Zhuan Sunxun's whereabouts, "Brother Qin Jia, you said Brother Zidan went out, what did he do when he went out?"
"We received news that Gong Shuqiu left Langya, most likely going back to Xianyang. Senior Brother went out to find out the news."
Nong Yu felt relieved when she heard this, knowing that the other party must have been recalled to unlock the Shiquan Jiazi Lock.
