On the other side, half an hour later, Yu Bai drove to the Cultural Lane of the city.

Unlike ordinary modern bookstores with clean windows and a wide range of new books, Wenhua Lane exudes a heavy flavor of the past.

Most of the shops here are small and dimly lit, with the air filled with the unique fragrance of old paper dust mixed with ink.

Most of the books are second-hand, and some are even rare and out-of-print.

A wide variety of old books fill every corner of every store, stacked from the ground to the ceiling, almost drowning people.

Yu Bai walked through the books, his fingertips brushing over the yellowed or fragile covers, carefully examining them.

Her eyes were focused and sharp, she didn't look like she was just strolling around, but rather like an agent carrying out a precise mission.

In a blink of an eye, nearly three hours passed before she finished walking through the short alley.

However, there are very few books that really catch her eye and that she finds useful.

After all, what she wants is not a book about love and romance, nor a difficult and obscure theory, but "dry goods" that can be put into use immediately and guide practice.

She simply stopped searching for a needle in a haystack and, based on her previous impression, selected a few small shops where the books were neatly organized and the owners looked smart and capable.

"boss,"

Yu Bai walked to the counter of a second-hand bookstore called "Hanmo Zhai" and spoke in a clear, cool and capable voice.

"I need a number of books, mainly on agricultural planting, animal husbandry, various handicraft techniques such as textiles, pottery, woodworking, ironwork, as well as basic mechanical principles, traditional smelting, and herbal medicine identification and preparation."

The boss was a thin old man wearing reading glasses. He raised his head when he heard the words, and a hint of surprise flashed in his eyes behind the lenses, and then turned into understanding.

"Girl, what you want...are all practical things." He pushed his glasses and said slowly, "There are fewer young people like this nowadays."

Yu Bai didn't comment, only said calmly: "Do you have it here? Or, can you help me think of a solution?"

"Yes, of course!" the old man perked up. "These books may seem like waste paper to others, but they are treasures to me! Some of them are so rare that you won't even see them on the market!"

The reactions of the owners of several other bookstores selected by Yu Bai were similar.

Which of the bosses in these alleys is not an old hand who has been immersed in books for decades?

Upon hearing Yu Bai's words, a flash of understanding flashed in their eyes. They were well aware of their own inventory and knew which dusty old books contained the true gold.

"Don't worry, girl. We have connections for all these! If there are some obscure places, I can ask other stores for you!" A middle-aged shop owner assured, patting his chest.

Sure enough, it didn't take long for Yu Bai to contentedly carry out a thick stack of books carefully bound with brown paper from those bookstores.

The quantity is not much, but it is the essence she urgently needs.

The price is naturally not cheap, but Yu Bai doesn't care.

This knowledge is a priceless treasure in Daqin.

After putting all the books into the trunk, Yu Bai started the car and drove away from Wenhua Lane.

She found a secluded corner and stopped. She looked around vigilantly and made sure it was safe.

With the cover of the car body, she disappeared silently from the spot and entered the strange space that only she could dominate.

As soon as he entered the space, the familiar fragrance of grass and trees hit him in the face. However, Yu Bai didn't care about enjoying this peaceful moment and couldn't wait to shout:

"Master Fusu! Master Fusu!"

Her voice was clear, with a hint of urgency and joy, echoing in the empty space.

At this moment, outside the east gate of the space, the First Emperor, dressed in black casual clothes, was discussing something in a low voice with his eldest son Fusu.

Fusu had a serious look on his face, and was obviously thinking about a difficult question raised by his father.

At this moment, Yu Bai's clear call seemed to penetrate the invisible barrier and reached Fusu's ears clearly.

Fusu's expression changed, a hint of joy flashed in his eyes, and then he bowed respectfully to the First Emperor: "Father, the immortal has summoned you, I will be back soon!"

Before he finished speaking, his figure disappeared out of thin air, as if he had never appeared.

The First Emperor looked at the place where Fusu disappeared. A trace of imperceptible envy and loss flashed across his deep eyes, and he sighed slightly.

"Alas, the fairyland..."

He murmured softly, his tone filled with a hint of longing and helplessness.

"I really want to go in and take a look... Unfortunately, that fairyland doesn't seem to welcome me."

It's not that he didn't try to get a glimpse of the mysterious space, but he could never get in.

However, this sense of disappointment was quickly replaced by the self-regulation ability of a great leader.

The First Emperor stood with his hands behind his back, his eyes looking into the distance, thinking to himself:

"Forget it, forget it. In this world, only my son Fusu has this destiny."

"That immortal seems to have only recognized Fusu as the middleman. Didn't all the benefits flow through Fusu and ultimately land on my head, on the foundation of the Great Qin?"

He thought of the food that appeared out of thin air, the miraculous treatments, and even the "strange books" he was studying that were enough to subvert his cognition.

How could we have obtained these without the help of immortals?

Thinking of this, the First Emperor's eyes suddenly lit up, as if a flash of lightning had pierced through the fog.

"Could it be that... the immortal doesn't mean that I should seek immortality and ascend to heaven as those alchemists say?"

He recalled the words "the people create history" and "serve the people" in "Selected Works of Mao Zedong", and thought of the "immortality" he had always pursued.

A bold idea took shape in his mind:

"Before, I only thought about seeking immortality, but I didn't expect that the immortals might not have the same intention."

"What she wants is for me to stay in the mortal world and use the spark of the Ying family to create a truly eternal and prosperous Chinese nation!"

Once this thought appeared, it spread like wildfire and quickly occupied his mind.

"Yes! It must be so!"

The more the First Emperor thought about it, the clearer it became.

"I guess the reason they don't let me set foot in that fairyland is because they're afraid I'll become intoxicated by its beauty and forget my responsibilities in this world."

After all, if he, an emperor, were obsessed with immortality and neglected worldly affairs, who would oversee the great affairs of the world? Who would put those "advanced" ideas into practice?

Thinking of this, the unhappiness and regret in the First Emperor's heart suddenly disappeared, and were replaced by a sense of pride and relief at being entrusted with an important task.

"So, it's not that the immortal dislikes me, but rather that he has high hopes for me... and for the Great Qin!"

A meaningful smile appeared on the corner of his mouth. His mood, which was originally a little complicated due to Fusu's "special treatment", has now turned into an even more magnificent ambition.

Since the immortal values ​​this human world and the future of China, then he, Ying Zheng, will fulfill her wish and create a prosperous dynasty unprecedented in this mortal world!
