After broadcasting the ancient times live, I handed the system over to the state.

When she got back, she shared it with Bai Qin, Liao Ming, and the others.

Liao Ming said with a smile, "There were many pandas in previous dynasties, and there are also many extinct species. It would be great if some of them could be handed over to future generations for protection or research."

This is what piqued Zhu Qinggu's curiosity. She did some research and suddenly remembered the popular science she had read in a novel before. There used to be elephants in Henan. Otherwise, why would Henan be abbreviated as 'Yu'?

The character '豫' in oracle bone script depicts a person leading an elephant, hence Henan also means the land of elephants.

Zhu Qinggu became increasingly curious and searched for a lot of related information.

During the Shang and Zhou dynasties, there were still many elephant herds in the Yellow River basin, as can be seen from the oracle bone inscriptions of the Shang dynasty, and elephant bone fossils have also been unearthed at Yinxu!

At that time, the climate in the middle and lower reaches of the Yellow River was warm and humid, much like Yunnan today, which was also quite suitable for elephant herds to live in.

After the Qin and Han dynasties, the climate gradually turned cold, and the elephant herds began to migrate to the warmer south, such as to the Yangtze River basin. Moreover, during the Tang dynasty, people had already developed Lingnan, which would have destroyed the elephant herds' habitat, so the elephant herds would definitely migrate again.

Sure enough, Zhu Qinggu saw the same thing. The climate became even colder after the Song and Yuan dynasties, and the elephant herds gradually migrated. Now, wild elephant herds in our country only exist in Yunnan Province, and they are endangered protected animals.

So she immediately went to the Tang Dynasty to see not only how Tang Dynasty scholars excavated and preserved oracle bone inscriptions, but also to see the elephant herds of that time.

When she arrived at the site of the oracle bone inscriptions, she saw many experts and scholars from later generations mingling with these ancient people, some choosing to excavate on-site, some choosing to restore and protect them, and some choosing to decipher the contents.

Whether modern or ancient, people nowadays are all tanned and have weathered, dark complexions.

Those who choose to stay here do so not only because of the projects they are working on, but also because they are very interested in ancient records, which is why they are able to persevere.

An old professor, along with his students and an ancient person, carefully brushed away the dust from the oracle bone inscriptions inside the tent.

Zhu Qinggu stood there for a long time, and they didn't notice her, but she heard the name of this ancient person, Lu Deming.

After searching the system, Zhu Qinggu realized that this person was also someone of great importance!

Lu Deming's "Explanations of Classics" examines the texts, phonetics, and exegesis of Confucian classics from the pre-Qin period to the Tang Dynasty, and is an important book for the study of ancient classics.

This book also preserves a lot of lost ancient texts' phonetic and semantic information, providing a basis for later scholars to study the classics. It can be said that the author is a genius!

It seems that he now needs to study the writing and phonology of the pre-Qin period and even earlier, the Shang Dynasty.

I wonder whether the students who study this subject later will thank him or complain about him.

Zhu Qinggu was curious if there were any records about elephants here, but the old professor's student who was in charge of hosting them complained, "Don't even mention elephants, so far we've been cooking people every day, especially the Qiang people. It's making me curious about what the Qiang people taste like."

"You can't eat this!" Zhu Qinggu joked.

The student added, "So, in the Investiture of the Gods, making Boyi Kao into meat soup is a custom from that time."

Zhu Qinggu: "...What a hellish joke."

He shrugged. "Isn't the point of studying history to understand these things? For example, what cartoon did Shang Yang dislike watching the most? My Little Pony!"

Zhu Qinggu thought this person was quite a character; no wonder he had seen him getting along so well with everyone at the archaeological excavation site, whether they were from ancient or modern times.

"...If I ever get the chance to travel back to the pre-Qin period, I'll have you chat with Shang Yang."

Student: "6!"

After Zhu Qinggu circled around the area, he quickly led Bai Qin and the others to chase after the elephants. However, after teasing the baby elephant, they were chased away by the elephants.

The think tank ordered her to be prohibited from participating in such dangerous activities, sometimes just in case she had a sudden inspiration. Right now, she is more important than any protected animal or national treasure!

We can't just abandon this huge mess and run away, can we?

Zhu Qinggu felt a little embarrassed, and after a long silence, they began to observe Zhu Yuanzhang referencing the credit currency mechanism of later generations, but this time they were extremely cautious.

They don't want to fall into the same trap twice as they have in the past.

The Tang Dynasty was clearly also very interested in paper money. At that time, there was a shortage of copper, which was mainly in the hands of aristocratic families. However, thanks to Li Shimin and the propaganda of the imperial court, these aristocratic families were still able to maintain some power. But the further things went, the easier it would be for them to be divided.

Some people have chosen to surrender to Li Shimin. Since they can't beat him, they choose to join him. There's nothing shameful about that; it's just another way to protect their families.

On Tuesday, Zhu Qinggu broadcast live for a whole morning, letting everyone see the discussion on fiscal reform in the Ming Dynasty. People under the sky could see the shortcomings of this fiscal reform in the Ming Dynasty from the perspective of experts from later generations.

Those under the sky left satisfied.

After the live stream ended, Zhu Qinggu told the people under the screen that she needed to prepare for her final exams and would be back in a month.

The people under the sky felt a great sense of regret and reluctance. In fact, even if Zhu Qinggu didn't do any live broadcasts and just chatted with them, they wouldn't find it boring; in fact, they would find it quite interesting.

Studying and taking exams has always been a major focus for Chinese people, and even modern students cannot escape it; all they can do is offer their blessings.

Fortunately, the two episodes of "Romance of the Three Kingdoms" airing every night are still going on, providing some comfort to those who have worked hard all day.

Zhu Qinggu also officially joined the review team, more than a week earlier than her classmates, but don't overlook the fact that she didn't attend classes systematically and had been studying on her own intermittently.

Now she needs to go through all the courses. Thanks to the system, it helped her organize the knowledge points.

Wang Minghua and the others were still wondering if Zhu Qinggu would come back to take the exam.

Zhang Xiaosheng sighed and said, "She said she was coming back, she should come back, right?"

Xu Lingfang: "I feel like it was better when there were four of us. Now..."

Just as they were muttering to themselves, the door suddenly opened, and Zhu Qinggu appeared in the doorway. "I'm back. Weren't you going to take an exam? I'll treat you to dinner after the exam!"

The three people in the dormitory immediately brightened up.

This went on for several days in a row. She would come back when the exam was about to start, and after the exam, she would at most have a meal with them and then mysteriously disappear. Even when they were eating, someone would come to check the situation in the private room.

It was even stricter than last time; it seemed her level of secrecy had been raised again. Zhang Xiaosheng and the others guessed, but dared not ask.
