I, the opening commentator, Mythological Era

Chen Xu had transmigrated.

He had transmigrated to become the most famous professor in China’s history world, and his longevity was 109 years old!

At that time, he almost cried.

Fortunately, he had the system.

He could regain his youth by explaining history, and he could also obtain all kinds of strange abilities!

However…

Soon, he was shocked to find that the gap in civilization in this world was so serious!

"Professor Chen, what does the descendants of the Yellow Emperor mean?”

"Professor Chen, is the Battle of Zhuolu a poignant love story?”

"Professor Chen, what are the four great inventions?”

"Professor Chen, who is Pangu? Who was Nuwa? Why did Yu the Great want to control the flood?"

······

These retarded questions that even elementary school students in his previous life knew made Chen Xu dumbfounded."Wait, don’t drive yet about the Battle of Zhuolu. Let me tell you one by one!”
