Cambridge does not have a unified campus, with colleges, institutes, libraries and laboratories all located on both sides of the River Cam. A few days after Shima's arrival in Cambridge, Li Longsheng had been studying here for ten years: "Ladies and gentlemen, please look at Trinity College on the left, which is one of the most famous students in Cambridge, and has the most beautiful buildings and courtyards in Cambridge, from which Isaac Newton graduated. ”

It was dark, and the boat passed by the Math Bridge, which is said to have been designed by Newton, without the use of a single nail, and was built entirely of wood.

Twenty-one-year-old Qian Ke interjected: "Isn't this the mortise and tenon structure of a Chinese carpenter?" Master Newton, that's just that! ”

"Definitely! Science and technology are two different concepts, modern science originated in Western civilization and traced back to ancient Greece. Taking astronomy as an example, Europe has been trying to explain all the celestial records since ancient times, and then use mathematics to deduce future celestial phenomena and prove them through actual measurements. From Ptolemy in ancient Rome to Newton, no matter what kind of academic views they held, they all followed this path. ”

Huiyin's sister looked up at Li Longsheng and said: "I understand, science is not a trick or an ancestral craft, but a complete set of model deduction and empirical system. ”

The German philosopher Engels said that the end of the Middle Ages was inextricably linked to the decline of Constantinople. The New Age began with the return to the Greeks...... If the study of the history of theoretical natural sciences wants to trace the history of the occurrence and development of its own general principles today, it will have to go back to the Greeks. Li Longsheng summed himself up, "This spirit of ancient Greece, the source of Western science, happens to be possessed by Eastern civilizations." ”

Qian Ke nodded slightly, he is also an engineer after all: "Dr. Li, I can understand what you said, although China has skilled craftsmen, it cannot summarize its own technology as science, because it lacks a complete set of systems. ”

"Yes, Mr. Sai - what is science? Science is not a faith, nor a morality, nor a craft, but it speaks with evidence. Science is an attitude, viewpoint, and method, based on an ordered system of knowledge that predicts the forms and organizations of the objective world, and must be confirmed and reproduced through experiments. If it is only a whimsical idea, a miraculous skill, or a short-lived machine, it cannot be called science. ”

The moon hangs high over the River Cam and faces the Bridge of Sighs, which connects to St. John's College, an enclosed arch bridge that mimics the Bridge of Sighs in Venice.

"So is the Tomb Beast a science?"

The little king's sudden question made everyone on the boat fall into silence, as quiet as the Kangqiao in the dark night, infinitely intimidating, but there was a hidden murderous intention.

"The essence of the tomb beast is scientific, even a science far ahead of the development of the times, but its guiding ideology is non-scientific."

Putting away the artemisia again, Li Longsheng sat cross-legged on the bow of the boat, staring at the beautiful panes on the Bridge of Sighs, like a leopard print hiding under the moonlit night.

"What do you mean by that?"

"You've got it for all to see—Chanko, you're in control of the Four-Winged Angel Gravemon, flying from continental Europe to England. Two years ago, we tracked this flying beast across thousands of mountains and rivers and forced down on an isolated island in the Arctic ice sea, and almost lost its life. There are also the nine colors of the tomb beast of the little prince of the Tang Dynasty, and the tomb beast of the heroic An Lushan has ten horns and seven heads, their power does not come from metaphysics, as long as it is carefully studied, through scientific deduction and experimentation, sooner or later the principle can be found, whether it is mechanical, or the so-called 'soul'. That's why I'm not against 'soul machines'. ”

Xiaojun Wang chased: "Why do you say that its guiding ideology is non-scientific?" ”

"Perhaps, only Qin Beiyang, the descendant of the Tombsmith Clan, knows the core of the Tomb Beast. This is also the characteristic of all ancient Chinese skills - the family inherits the business from father to son, from man to woman, from inside to outside. Once the family is broken, the craft is also broken. ”

"As the saying goes: Church apprentice, starve master! From making tomb beasts to repairing toilets, this is the case. Qian Ke smiled bitterly, "It's no wonder, we can always see exquisite memories in ancient books, such as Zhuge Liang's wooden ox and flowing horse and repeater, as for the real thing......"

"You can only see it by digging up Zhuge Liang's grave!"

Sister Huiyin said coquettishly: "Brother Longsheng, it turns out that you are such a Cambridge doctor!" I hate tomb robbers and corrupt antiquities. ”

"In China, many mystical skills are often sacrificed to Feng Shui, Bagua, Zhou Yi, Ziwei, Yin and Yang, the Five Elements, and even Confucianism, Buddhism, and Taoism...... It cannot be said to be ignorant and superstitious, but at least it is non-scientific and cannot be proven repeatedly by experiments. How do you say to prove that the Taiping Heavenly Kingdom failed because the Qing Dynasty dug up the ancestral tomb of the Heavenly King Hong Xiuquan? And why is the royal mausoleum of the Qing Dynasty currently safe and sound, but the Qing Dynasty is still dead? ”

The prophet of the little county king said: "I am afraid that the mausoleum of the Qing Dynasty will suffer in a few years!" ”

"For Mr. Gu Hongming and Mr. Luo Zhenyu, the Qing Dynasty is not dead!"

Shima finally spoke, admiring his sister in the moonlight, even though his wife had just arrived in London from China.

Li Longsheng disagreed: "It cannot be said that the Chinese do not have the scientific spirit at all, the Spring and Autumn Warring States and ancient Greece are in the same era, the same small country is divided, and the ideological giants are multiplied." One is the maritime commercial civilization, and the other is the continental agricultural civilization. And we are closest to the ancient Greek Democritus' 'atomism', Heraclitus 'Logos', and the culmination of Aristotle's thoughts, is Mozi. ”

"Mozi?"

"It is a pity that China's greatest craftsman godfather, whose ideas were later banned and failed to pass on, together with his many great skills, determined that China would no longer produce the soil of modern science."

Qian Ke patted his head: "Ahhh Speaking of Mozi and craftsmen, I miss Qin Beiyang, I heard that he is still alive. ”

"Yes, I met him in Xinjiang and Dunhuang last year."

Sister Hui Yin asked in confusion, "Who are you talking about Qin Beiyang?" ”

"The one who holds the secrets of the Tomb Beast."

"What is a grave beast?"

The corners of Li Longsheng's mouth twitched slightly: "I hold the secrets of China's mausoleums and the world." ”

"Ladies and gentlemen, the night tour of the Kang River, the scenery is very good, when it comes to the tomb beast and science, it is like Zhang Dai's "Night Sailing Boat". Shima straightened his feet, half-lying in the boat, his hands on the back of his head, and only the moonlight on the bridge in his eyes, "And let the little monk stretch his feet." ”

"Brother Shima, are you laughing at my nonsense that I don't know about the Ming Dynasty?" The atmosphere on the boat was a little awkward, and Li Longsheng laughed again, "It's okay! Anyway! Knowing things - be sure to learn things first, and then know. ”

"Oops, the leaves are falling." A dead leaf fell to the forehead of Huiyin's sister, and she was sad like Sister Lin in the Grand View Garden, "Falling a leaf and knowing autumn, this beautiful time and scenery is about to pass." ”

"Dr. Li, let me hold the boat!"

Shima climbed to the bow of the boat, and Li Longsheng instructed him on how to maintain his balance, in case he fell into the Cam River, it would not be easy to fish in the dark.

The artemisia staggered a few times, and hit the reeds by the river, and several white swans were startled and took off into the night sky.

Hui Yinxin chanted Li Qingzhao's "Dream Order": "I often remember the twilight of Xiting, and I am drunk and don't know the way back." Returning to the boat at night, he strayed into the depths of the lotus flower. Fighting, fighting, startling a shoal of gulls and herons. ”

"Good!"

The four men on the boat applauded her in unison.

Shima looked up at the sky where the swans flew by, the moon was dim, and the Milky Way was flickering, so he held the artemisia and stabbed deeply into the silt of the Cam River. Hold a penny,

Wander to the greener grass;

Loaded with a boatload of starlight,

Sing in the starlight.

But I can't put on songs,

Quietly is the parting sheng flute;

The summer worm is also silent for me,

Silence is Cambridge tonight!

Quietly I'm gone,

As I came quietly;

I waved my sleeves,

Do not take away a single cloud.

Hearing "But I can't play the song" and "Silence", Sister Huiyin, who was originally going to sing a song of Uncle Li and "Farewell", pursed her lips and drifted with the current, as if the sky was full of stars falling into the Chengkang River, and a boat of people was floating and sinking...... Early the next morning, Huiyin's sister left Cambridge and was going to return to China with her father Lin Changmin.

Li Longsheng, Xiaojunwang, and Qian Ke waved goodbye at the gate of King's College, Cambridge, and Shima rented a carriage to take her to the train station.

Late autumn in England is bleak, and the fallen leaves are rolled up in front of the eyes. According to the old Chinese calendar, today is the first day of October, the Winter Clothes Festival.

On the lawn of King's College, under the four-winged angel tomb beast and the copper coin pattern airship in the round sky, a doorman sent a telegram. Li Longsheng read out an English message on the spot, to the effect that he was invited to go to Shanghai, and that the round-trip fare and ferry tickets had been remitted through the post office.

The inscription of the telegram - Qin Beiyang.

Qian Ke also frowned and said, "A few days ago, I received the same telegram in Germany, which was also sent by Qin Beiyang. ”

"What a coincidence!" The little king nodded and said, "Yesterday, I received the same telegram in London!" Invite me to Shanghai. ”

Shanghai! Shanghai!
