"I don't do it." Chen Xian frowned impatiently, and strode towards Sun Xiaosong, who was three points more shabby than himself when he first came out of prison.

Xiao Liang immediately followed Chen Xian nervously, looking at her tense face, she was obviously ready to protect Miss's sweetheart at any time.

Sun Xiaosong saw Chen Xian striding over, he was stunned, he raised his hands, his eyes wandered, and he said in a restrained manner: "The gentleman doesn't move his mouth!" Besides, even if you want to fight, you have to wait until I'm full! ”

Chen Xian stopped at his desk, sat down opposite him unceremoniously, and said, "Test your question." ”

"Alas!" Sun Xiaosong found that this person had no intention of making a move, so he breathed a sigh of relief, and immediately said angrily: "I thought you were a man, but I didn't expect it to be Wendou." ”

After speaking, he waved his hand disdainfully, buried his face in the noodle bowl, and sucked the noodles vaguely and said: "I have no interest in poetry, the Four Books and the Five Classics have long been dusted in the house, and I don't read any other classics. ”

"Kong Ming lantern, why can it go to the sky?" Chen Xian said flatly.

Sun Xiaosong suddenly lifted his face from the bowl, sucked a noodle in his mouth, and sucked it into his mouth before saying, "Naturally, it's because there is a fire candle in it." ”

"Why are pieces of paper fluttering on top of the charcoal basin?" Chen Xian continued.

"Because...... The heat flow is upwell. Sun Xiaosong narrowed his eyes, and his expression became serious.

"Why did you fall off a cliff? Why does it fall downwards? Why does the lid of a boiling kettle float? Why do you see the sails first when you watch a boat by the sea? Chen Xian smiled and threw down a few questions, then stood up, turned around and walked out the door.

"Childe, Childe! Wait for the hedge! The little maid followed out in a panic.

Sun Xiaosong's eyes widened, and he watched Chen Xian go out without saying a word.

He hesitated for a few seconds and then reached out to support the edge of the table, subconsciously wanting to stand up, but he caught a glimpse of the bowl of Yangchun noodles that was still half left, so he copied the bowl up, swallowed it in two gulps, grabbed the small pot of wine on the table, and flew out.

As soon as he went out, he saw the pair of master and servant in the crowd walking eastward with idle steps, Sun Xiaosong subconsciously pulled the scarf on his head and walked over with faster steps.

He hurried through the crowd, and when he saw that the master and servant had just turned to look at him, he asked at the first question, "Why?" ”

"Physics, the principle of all things." Chen Xian smiled and narrowed his eyes: "Books still have to be read!" Xunzi has clouds: where you know, human nature is also; It can be known that the principle of things is also. ”

Sun Xiaosong completely lost his previous appearance, and at this moment he arched his hand quite convincingly: "The teaching is reasonable, dare to ask the honorable surname?" ”

"Chen Xian, words do." Chen Xian said.

Sun Xiaosong seemed to be a little bad at communicating with people, and his speech was a little slurred at this time: "Mr. Chen, Xingzhigongzi, you, can you tell me the answers to the previous questions?" ”

Chen Xian just bowed his head indifferently, and pretended to be unfathomable: "Take me to your house to have a look." ”

Seeing that Childe was going to this madman's house, Xiao Liang suddenly became anxious, and only felt that this madness would not be contagious, so she shouted anxiously: "Childe, let's go to Huancailou!" Miss should be busy, too! ”

Sun Xiaosong heard Chen Xian take the initiative to go to his home, and his heart was secretly happy, at this moment, when he saw this little maid inserting a foot, he suddenly looked anxious, and then found out the key information point of "Huancailou" from this maid's words, and tried to set it almost and said: "I heard that Huancailou has been very powerful recently, the former Oiran Lu Xiaochai did not mention it, and there was a Xiangyun girl, it is said that even Lu Xiaochai's sweetheart Chen Xingzhi wrote a word to her, and it seems that she intends to abandon it from the beginning to the end and throw herself into Xiangyun's pomegranate skirt......"

Speaking of this, he suddenly swallowed his saliva, raised his eyes to look at the person in front of him, and asked in amazement, "What did you say your name just now?" ”

"Chen Xingzhi." Chen Xianpi looked at him with a smile and raised eyebrows.

……

Sun Xiaosong pushed open the wooden door with the mutilated bottom corner, and led Chen Xian's master and servant into this depressed courtyard in the north of the city, scratched his head a little embarrassedly and said, "Chen Gongzi, my place is broken, you will sit on it!" ”

After speaking, he slapped the door of his head, walked quickly to the house, and said in a rummaging cabinet: "Yes, yes, yes, I am still a little bit of Longjing before the rain, and it was when I was settling accounts for Liu Dahu a few days ago, so I went from there...... Borrowed! ”

Chen Xian ignored him and looked around the courtyard with his hands.

Sun Xiaosong is obviously relatively poor, the courtyard is a compacted mud soil, in this just melted snow weather, a foot of black mud is a foot, three earthen houses appear dirty to build on the north side, the northwest corner is a few bundles of wood, next to a strangely shaped three-wheeled car, the front of the car is actually made of a wooden board like a pedal.

"What kind of car is this?" Chen Xian glanced at the small wooden cart that was seven points similar to a modern three-wheeled bicycle, but had no transmission, and wondered.

"Tea ready!" Sun Xiaosong walked out with a large clay jar, and when he heard Chen Xian's question, he scratched his head and responded: "I originally wanted to put boiling water on the bottom of the body, and then use the flame to continuously heat it, and the hot air will be discharged from the bottom, and the car will be lifted up......."

"Flutter!" Chen Xian couldn't help laughing, he wanted to get the steam suspension tricycle out, he patted the shoulder of Sun Xiaosong, who looked embarrassed, and said with a smile: "It's too heavy, why don't you try to use paper first." ”

"Paper ......" Sun Xiaosong scratched his head and said embarrassedly: "Actually, I also know that I am whimsical, this wooden board is so heavy......"

Speaking of this, he blushed and said crampedly: "However, I am shy in my pocket, and it is really difficult to experiment with paper, but I have tried to use lotus leaves, but I still can't fly." ”

Chen Xian was stunned for a moment, and then came to his senses, as the saying goes, it is true that the poor are rich and martial, but the output of paper in this era is limited, and the production source is controlled by several major commercial houses.

He thought about it again, the poor scholar in front of him and Leonardo da Vinci lived in a similar era, but the social environment in which they lived was different. This is all inferior, only in the Ming Dynasty, where the reading was high, any invention full of imagination was criticized as "strange and skillful", and the household registration system that limited people's subjective initiative even arranged a career for you, your son, and your children and grandchildren on the day you were born......

At this time, Europe had already opened the prelude to the Age of Navigation with the progress of cartography, geography, and astrology.

"Chen Gongzi!" Sun Xiaosong saw that Chen Xian didn't speak for a long time, thinking that he was disdainful of his poverty, so he scratched his head and said embarrassedly: "I will definitely do two more jobs in the future, can you tell me the answers to those four questions now?" ”

Chen Xian's gaze swept over his sincere face, and he glanced at the west wing behind him, the door of the room was open, and a large wooden table could be vaguely seen inside.
