Shen Qingqing was so happy that she couldn't stop smiling. The tall building was magnificent and stood in the middle of the space, with a faint halo around it. It looked full of technology, with a cold metal texture and a cold light.

In her last life, Shen Qingqing used the upgraded library to learn a lot of knowledge and skills, including the enemy's language. In her last life, she mastered the enemy's language by studying the language courses in the library, and was able to translate the enemy's secret documents.

Later, she discovered some advanced training programs in the enemy country. She provided her spiritual spring water to help Lu Yunshan's soldiers improve their physical fitness, and with the help of advanced training programs and methods, the combat effectiveness of Lu Yunshan's troops was greatly improved.

It was also because of this that he was able to be promoted step by step from battalion commander to deputy regiment commander and regiment commander.

It can be said that without the help of her space, Lu Yunshan would never have been able to become the team leader.

Shen Qingqing couldn't help but feel secretly delighted. She wanted to see how Lu Yunshan would get promoted and how he would climb up step by step without her help this time!

She approached the library and pushed open the door. There were three floors inside, and each floor had areas for different types and professional books.

Shen Qingqing observed the library carefully and found that it had undergone some changes compared to when it first appeared.

She remembered clearly that when the last library first appeared, it was just a short building, not very tall. The books stored in it were far less than the current ones, and the types were not as complete as this one.

She was a little confused. What exactly caused these changes? Shen Qingqing was confused. She flipped through the books and found that the book she had read last time still existed in this book.

This made her breathe a sigh of relief. Shen Qingqing looked up. Light passed through the huge glass above her head and entered the room, illuminating the library.

Shen Qingqing sighed slightly. She didn't expect that this library was so much bigger than the previous one. But, this is also a good thing, isn't it?

Shen Qingqing found the books she had studied last time, found a table and began to review. She was very excited in her heart, because if these things could help Lu Yunshan, they would definitely help Zhou Yuanzheng.

She was just an ordinary person, and after so many years, she had forgotten a part of the contents of these books. She went to the center of the library and set the huge clock hanging there to ten times the speed.

This was the function of the library that she had figured out last time. The flow rate of the clock hanging in the middle of the library could be adjusted, and she adjusted it to ten times the speed. The flow rate of time in the library was one tenth of that outside. In other words, if she studied here for ten hours, only one hour would have passed outside.

Although she didn't understand the principle behind it, she didn't feel tired or sleepy when studying in the library. Instead, she could always stay energetic.

Shen Qingqing opened the book and began to study seriously. These things could help Zhou Yuanzheng, so she hoped to learn them quickly.

Shen Qingqing flipped through the book she had read before and found that she still remembered most of the content, so she just went through it briefly.

She opened the book catalog and chose medicine from a variety of subjects.

This time, she is much happier than her last time. She is not restricted at home and has a lot of time to do as she pleases.

Shen Qingqing thought that learning medical skills would be able to help many people.

The medical level in this era is not very high. It would be very useful if she could master these contents.

Although Shen Qingqing didn't know how the space came about, nor did she know where the library that appeared out of thin air in the space came from. But she only knew one thing, that is, the source of the space and the library, the level of technology must be much higher than that of her world.

So from that day on, Shen Qingqing used all her free time to study. Fortunately, the canteen work hours were not much, only four hours a day at most.

Zhou Yuanzheng went out early and came back late, so she didn't have to worry about being exposed. So these few days, whenever she had time, she would go to the library to study.

After choosing to study medicine, the library will tailor a study plan based on Shen Qingqing's level of knowledge.

There are video classes and practical classes, but Shen Qingqing’s current level of medical understanding is too low to take practical classes.

But she started from the most basic content, and also had to learn chemistry and do some experiments.

This made Shen Qingqing's already busy life even more stressful, but she was both sad and happy.

There were teachers teaching video courses in the library. Although she had never heard of their names, she could feel that these teachers were highly skilled and knowledgeable, and most importantly, their explanations were simple and easy to understand.

Although she had not heard any news about these teachers in the previous or current period, they must be leading figures in the academic world.

Because of this, Shen Qingqing cherishes her study time even more. Not everyone has such convenient conditions as her, and can get this level of teaching without leaving home.

That night, after Shen Qingqing finished her work, she went home.

She got some rice in the cafeteria in advance so that she wouldn't have to cook dinner later. By squeezing out some time, she could study a little longer. She wouldn't have time to study when Zhou Yuanzheng came in the evening.
