They can talk about farm work in ancient times in great detail, but know nothing about modern tools.

Even the people in the mountains would not be as ignorant as them.

It's normal to be wary of others. If someone told you that you had arrived five hundred years in the future, anyone would be wary of the people around them.

If they are pretending, what are they trying to achieve?

The man named An Jingzhi reported everything he did in the history field to Li Hongnan.

The other party did help point out a lot of details recorded in ancient books. Many books have been lost after wars and the entire country has not found the content. However, An Jingzhi knew that this could prove some problems.

But there are still some things that cannot be proven.

"During the Kaihuang period of Dongqing, that An Jingzhi could even tell the chief examiners of the provincial examinations. Many of them were not recorded in ancient books, and we have no way to tell the truth from the false." Yang Dongqing said.

Suddenly, Li Hongnan's cell phone rang.

Yang Dongqing couldn't hear the specific words, he only knew that the voice on the other end of the phone was very excited.

"What's wrong, leader?" Yang Dongchen couldn't help asking when he saw Li Hongnan looked a little shocked.

"They dug up a tomb from the Dongqing Dynasty! The tomb owner was an official during the Kaihuang era. Perhaps we can find some information."

"Then can we confirm whether what An Jingzhi said is true?" Yang Dongchen was also a little excited after hearing this.

Many of the historical issues pointed out by An Jingzhi are very controversial, mainly because there is no clear evidence to prove that what he said is correct.
