From exquisite and practical pottery firing methods to complex and sophisticated smelting and forging techniques.

From the mining and utilization of precious and scarce metals to the essentials of weapons manufacturing related to national security...

It can be said that every aspect of production and life in the world has been thoroughly and meticulously explained and recorded in this book.

Excitement shone in Su Jinyun's eyes. There was such a detailed book in the world, and she had only been fortunate enough to see it today. She regretted not having seen it sooner.

Although she cannot fully understand many of the facts and terms in the book with her current knowledge and experience,

But she knew that anything that could be introduced and explained alongside important fields such as agriculture and weaponry must be of immeasurable value.

Presumably, each of these records has been carefully researched and verified through practice by our predecessors.

If used properly, it will surely bring great benefits to the prosperity of the country and the well-being of the people.

So she became even more engrossed in carefully examining every page and every line of text in the book, studying and savoring each word and sentence, and uncovering more wisdom and treasures from it.

Qin Qianlu finished her training and returned to her room, covered in sweat and exhausted.

She first quickly washed up and changed into clean and refreshing clothes before walking lightly into the library.

At first glance, you can see Sister Su sitting there, completely absorbed in her book, her expression focused and serious, as if everything around her is irrelevant to her.

Seeing this, Qin Qianluo didn't make a sound to disturb her. She simply walked quietly to the bookshelf and picked up the book she hadn't finished reading before.

Then he sat quietly next to Sister Su and continued to read. For a moment, only the soft sound of turning pages remained in the library, quiet and peaceful.

Su Jinyun was engrossed in the book "Tiangong Kaiwu" when she sensed someone sitting down next to her. She suddenly looked up and held the book high in her hands.

His gaze turned eagerly to Qin Qianluo, his voice trembling with anticipation as he asked, "Qianluo, do you still have this book?"

Qin Qianluo gently raised her eyes, her gaze slowly falling on the cover of the book in her hand, where the four ancient and vigorous characters "Tiangong Kaiwu" (The Exploitation of the Works of Nature) were displayed.

As if carrying the weight of history, it suddenly leaped into her eyes.

Her expression instantly became somewhat stunned, as if she had been struck by this sudden discovery, and she simply nodded subconsciously and mechanically.

But a storm raged within her, filled with regret. She couldn't help but silently ask 001...

"001, why didn't you think to remind me before that this library actually has such a precious book as 'Tiangong Kaiwu' hidden in it?"

If we had known about its existence earlier, why would we have spent so much effort and time trying to find ways to improve people's lives?

001 was also a little confused at this moment. It flapped its wings and flew lightly to Qin Qianluo's shoulder and landed.

The two, one human and one phoenix, stared blankly at the book in Su Jinyun's hands, their eyes filled with regret.

"Luo Bao, I didn't expect this either." 001's voice carried a clear hint of frustration.

Qin Qianlu felt somewhat helpless, but she also blamed herself for the situation, as her thinking was too narrow and limited.

Why didn't I ever think of searching for these precious books in the library before?

In the past, I would only ask my father to print the 001 method after I encountered a problem.

However, they never realized that the library in this space contained books of almost every category from past to present lives.

Thinking of this, a glimmer of light rekindled in her eyes, and she asked...

"Since there's *Tiangong Kaiwu* (The Exploitation of the Works of Nature), do you also have *The Barefoot Doctor's Manual*, *The Militia Military Training Manual*, *The Friend of Dual-Use Personnel*, and the complete *Yongle Encyclopedia*?"

Upon hearing this, 001 immediately focused his attention and quickly began searching. After a short while, he said, "Luo Bao, these books are indeed all there. However, gunpowder has not yet begun to be developed."

Much of the content in this "Militia Military Training Manual" is related to advanced military equipment, so it would be inappropriate to take it out rashly at this moment.

It might cause unnecessary trouble and suspicion, so it's best not to bring it out yet.

As for the other books, Su Xiang could take them with him, but the Yongle Encyclopedia contains extremely rich and profound scientific knowledge.

If research and promotion were to be conducted too early at this time, it would be difficult for people to understand given the current level of social awareness and basic conditions.

Moreover, conducting scientific research too early could have unpredictable impacts and effects on the surrounding environment.

Moreover, it also contains detailed records of highly destructive weapons and equipment such as muskets and cannons.

These things need to be considered before they are shown to the public, after gunpowder has been successfully developed.

If we were to release everything now, it might arouse suspicion.

Su Jinyun, who was standing to the side, was a little anxious as she listened to these words, but 001's words made perfect sense.

Although she was extremely anxious and wished she could immediately get her hands on all the books that could promote the country's development, reason told her that doing so would only backfire.

If she were to suddenly present too many books that were beyond the comprehension of this era, and everyone showed no suspicion towards Qianluo, it would actually make Qianluo suspicious.
