The jade water went around and around most of the Qin Kingdom, and finally merged into the East China Sea from Yundu.

Thanks to this, Yundu has become an important port for the Qin State to the outside world. Whether it is a boat from the inland or a steam freighter from the West, most of them dock here. In just a few decades, Yundu "occupies half of the wealth in the south of the Yangtze River".

Qianzhou walked on the streets of Yundu, and even after more than a month, it was still hard for him to believe that he had come to the world of his pen.

Bucket arches and glass paintings look out on the street, postmen on bicycles nimble through the gaps in the carriages; drinkers who have drunk all night help each other out of the tavern, and the bartender is ready to close after wiping his glasses; while Xiao Er in the teahouse next door has already made the first pot of tea today; the street is crowded with people, cheongsam, windbreakers, skirts, and suits proclaim the reputation of Yundu as the "fashion capital" in their own ways. Looking up, black smoke was billowing from the factories outside the city, and the rumbling of a steam engine could seem to be heard in my ears.

Qianzhou is a little abrupt, this absurd and realistic everything gives people a wonderful sense of historical intertwining, like the old Shanghai in the movie, and like the old London in the game.

"It's the best of times, it's the worst of times. ”

"This is the year of wisdom, and this is the year of foolishness. ”

"This is the ruins of silence, this is the miracle of rebirth. ”

Qianzhou muttered, completely oblivious to the increasingly strange eyes of the pancake aunt.

"Housheng, your bread is ready. Read less, don't think about what you don't have all day long. Auntie stuffed the cake into Qianzhou's hand, but still forgot to nag a few words.

Qian Zhou smiled bitterly and paid the money and walked towards Yundu University.

Anyway, who invented this practice of adding cheese to pancakes?

............

Yundu University, established in the period of "academic system reform", has a history of nearly 70 years. Yundu University has attracted many Western scholars and domestic Confucians, and today Yundu University has become one of the "three pillars" of Qinguo University.

Qianzhou crossed the path between the sycamore and walked into a large classroom with a capacity of 100 people. The classroom is in the shape of a staircase, low in the front and high in the back, and the students are talking in twos and threes, all of which are noisy.

As soon as Qianzhou walked into the classroom, a student asked, "Mr. Qianzhou, are you still teaching today's arithmetic?"

The students called Qianzhou "sir" on the one hand, in recognition of Qianzhou's arithmetic attainments, and on the other hand, it was also a kind ridicule of the teacher who was about the same age as them or even a little younger.

Qianzhou shrugged his shoulders, "Who let Professor Finn's illness not heal?"

Qianzhou was penniless when he first came to this world, but fortunately, Yundu University was recruiting teaching assistants. Qianzhou got this job with his good math skills so that he would not starve to death on the streets.

"What are you discussing?" Qianzhou asked curiously, looking at the gathered students.

"It's a natural disaster. A student of Qianzhou's age handed over a photo, "My uncle passed through Loulan when he came back from trading in Xizhou, and the whole of Loulan was destroyed by the 'Red Wind'. ”

Qianzhou took the photo. In the distance, in the background, there is a desolate desert, and an ancient city rises quietly in the dim sun. The red crystal salt makes up the architecture of the ancient city, and the crystal salt statues standing in the streets look like the handiwork of masters, and the wrinkles and frightened expressions of their clothes come to life—they were once living flesh and blood. Just a few days ago, the ancient city was bustling with traffic.

[Natural Disaster: Red Wind] - Everywhere you pass is red.

Qianzhou pursed his lips, and he suddenly felt a little disgusted with the world he wrote. In the face of various natural disasters, human beings are just ants that steal their lives, and there are countless treacherous things beyond the eyes of mortals.

And the students are still discussing with great interest, after all, natural disasters are still far away from them, aren't they?

A lesson is not long.

When Qianzhou finished writing the last conic curve equation, the audience was silent. Looking at a pair of godless eyes, Qianzhou helplessly shouted "get out of class".

As if a piece of ice had been thrown into a pan of oil, the whole classroom quickly became noisy, and the students left the classroom in twos and threes.

Qianzhou accidentally saw a girl wearing black-rimmed glasses leaving alone through the back door, and it didn't seem to be a student of Yundu. However, Qianzhou didn't care, Yundu University has always been open, as long as it does not violate Yundu's discipline, anyone can come to audit.

As soon as class ended, Qianzhou went straight to the library.

The history of the Yundu University Library is even earlier than that of Yundu University itself, and in terms of scale, only the National Library of the Imperial Capital can be slightly better.

After coming to Yundu University, Qianzhou would come to the library whenever he had time, and he was eager to understand the history and details of this world, and to understand the strangeness and magnificence of the places where his pen had not touched.

As soon as Qianzhou sat down and opened a copy of "The Secret History of Xizhou", someone walked up to him and shouted softly: "Mr. Qianzhou?"

Qianzhou raised his head, and the person in front of him was the girl who had just been auditing his class.

The girl's long hair was tied in a ponytail at random, and the rest of the part covered her forehead obliquely, and with a pair of thick black-framed glasses, the girl's posture was almost completely covered, and only the girl's delicate skin like jade could be seen. The wide gray coat obscured the delicate curves, and only the straight, slender legs were exposed.

"What's wrong?" Sensing Qianzhou's gaze, the girl brushed the hair around her ear and smiled generously.

"Nope. Qianzhou lowered his eyes.

It turned out to be flat glasses.

"What's the matter?" Qianzhou asked again.

The girl pursed her lips and took out a piece of paper from her pocket: "I have a few arithmetic questions I would like to ask." ”

Qianzhou took the paper, and on it were several rather complex multiple integrals, but they could be solved quickly using the Gaussian formula. Qianzhou picked up the pen and calculated it with his hands.

The girl lowered her head with interest and looked at the Qianzhou calculation.

A few strands of hair hung down to Qianzhou's ears, tickling him. And the tip of the nose can already smell the faint fragrance of the girl's body, like an elegant peony when singing.

"Can you come over a bit, excuse me. Qianzhou didn't raise his head, only the complicated symbols and formulas in his eyes, and he didn't notice the girl's bulging cheeks at all.

The girl straightened up and looked at Qianzhou's face in all kinds of chatter.

Qianzhou's eyebrows and eyes are soft, with a bookish atmosphere, and when he is serious at this time, his eyes are like a rising lamp, and his delicate face has a timeless charm.

"It's better than in class. The girl said secretly in her heart.

"It's solved. Qianzhou interrupted the girl's thoughts and handed the paper back.

The girl frowned after reading the answer, but she was quickly relieved, "Thank you, sir, these two are tickets for the performance of the 'Shenshang Troupe' at the Yundu Grand Theater, please accept it." ”

After that, without waiting for Qianzhou to refuse, the girl walked out with brisk steps, like a dashing wind, and like a dancing fire.

"That's right," the girl turned around and winked at Qianzhou, "My name is Xie Qingfeng." ”
