Tang Mingxi frowned slightly, searching for the answer to this question in her brain.

Although she was proficient in archaeology, she devoted all her energy to prehistoric civilization, and had little knowledge of other periods.

It is not easy to recall the answer. Just as Tang Mingxi is ready to raise her hand to speak, a clear voice suddenly comes from the back of the silent classroom.

"Baode Tongbei is the earliest metal coin of Yan state and the ancestor of bronze coin of Yan state."

Everyone in the class couldn't help but focus on it.

When it was discovered that the one who opened his mouth turned out to be night Hong, he could not help but send out the exclamation of worship.

"Worthy of being the monitor, I know that!"

"Bang!" Tang Mingxi pulled the mink fur on the mink coat unhappily. "For a moment, I hesitated, but I let that guy take the lead."

At this time, Yehong had already finished reading the archaeology of ancient characters and inscriptions.

At this time, he was closing his book and quietly digesting the knowledge of that brain with his eyes closed.

In the middle of digestion, there is a problem in my ear.

Night Hong also no matter who asked, subconsciously will answer out.

Gu Xinlan looked at night Hong, the proud smile on his face could not help but froze, and the corner of his mouth couldn't help smoking.

"Cough, I didn't expect that this student would know the answer, ha ha... Ha ha ha --"

after a few dry laughs, Gu Xinlan regained her spirits and gnashed her teeth in her heart and said, "Stinky boy, I don't believe this second question, you know it!"

She sorted out her emotions and went on to ask, "the second question: what is Pei Ligang culture?"

A problem, she is tightly staring at night Hong.

The students were stunned again, scratching their ears and scratching their cheeks, but they didn't know the answer.

While Tang Mingxi was still thinking, Yehong, with his eyes closed, once again talked: "Peiligang culture is the Neolithic culture of the Central Plains province of the burning state.

It is one of the earliest Neolithic culture in Central Plains.

It was named after the excavation and identification of Peiligang village in Central Plains province.

Pei Ligang culture is a burning country...

"stop

Gu Xinlan couldn't help screaming.

Harsh sound, so that all the eyes of the class are focused on her body.

Yehong also opened his eyes.

Gu Xinlan's scream made him wake up from the state of digesting knowledge.

At the moment, he was also a little confused, obviously did not know that the class had begun.

What's more, he has unconsciously offended Professor Gu Xinlan twice.

For the first time, Gu Xinlan was looked at with strange eyes by so many students. Gu Xinlan's face flashed with embarrassment, but in her heart, she was more and more angry with Yehong.

"It's you who let Professor Ben behave so badly!"

A burst of anger in my heart, accompanied by Gu Xinlan's voice is also a little hoarse.

"The third question..."

GU Xinlan almost squeezed his voice out of his teeth: "this classmate, I ask you:" what is cloth currency? "

This question is actually a name, let Ye Hong answer.

Gu Xinlan has been infuriated to Daze the mind, it was forgotten that this is the test of the whole class.

This kind of gaffe is the first time for her to teach for so many years.

The students were stunned, but at the same time they focused their eyes on Ye Hong.

Even Tang Mingxi gave up thinking and looked at Yehong for a moment.

What happened at this time.

Even so, night Hong has no intention to retreat.

Because of this question, he really understood it.
