After calling Professor Gu, Ouyang Ping replaced Liu Dayu with Wei Zimin, at this time, Ran Shimei and his wife must be controlled in the front yard of Ran's house, and Ran Shimei and his wife cannot go back to Ran's backyard until they figure out the origin and identity of the wrench.

Yan Jianhua, Ouyang Ping and Liu Dayu walked out of the alley, all the way to the east, towards the intersection of Mafu Street, Ouyang Ping and Professor Gu said that they would wait for him at the entrance of the street.

After listening to Ouyang Ping's explanation on the phone, Professor Gu immediately decided to invite Peng Dawei, deputy director of the Provincial Museum, over. Deputy Director Peng is an expert in the study of cultural relics of the Ming and Qing dynasties, and he has published many articles related to the cultural relics of the Ming and Qing dynasties in newspapers and magazines, and is an authority on the study of cultural relics of the Ming and Qing dynasties in China.

This is exactly what Ouyang Ping hopes, and with the two experts Professor Gu and Deputy Director Peng coming forward, they will definitely be able to figure out the origin and identity of the wrench.

At 9:55 a.m., a car slowly stopped in the open space in front of the Changsheng antique store.

Ouyang Ping, Liu Dayu, and Yan Jianhua ran out of the teahouse (there was a teahouse diagonally opposite the Changsheng antique shop, and the name of the teahouse was "Ke Changlai").

Ouyang Ping opened the car door.

Professor Gu got out of the car, and immediately after, a man about 55 years old walked out of the other car door, and this person was Peng Dawei, deputy director of Peng. He wears a peaked cap, a fur coat, and a brown handbag.

Ouyang Ping led the two experts into the "guest frequent" and sat down in a corner. There was no one in the teahouse yet—the teahouse was only open in the afternoon.

There were three cups of tea on the table, and Ouyang Ping, Liu Dayu and Yan Jianhua had been waiting here for a long time.

After Professor Gu and Deputy Director Peng sat down, a waitress brought two cups of tea.

Yan Jianhua took out a wrench from his purse.

Professor Gu and Deputy Director Peng, you look at me, I look at you, and their eyes are full of surprise, to be precise, it should be shock.

"Old Gu, you look first." Deputy Director Peng said.

Professor Gu took the wrench in his hand and looked at it for a while, then handed it to Deputy Director Peng.

After looking inside and out, Deputy Curator Peng put the wrench in the middle of the table.

"How's it going, two experts?" Ouyang Ping was looking forward to the opinions of the two experts.

Deputy Director Peng opened the brown leather bag, took out a very delicate small box from it, slowly opened the lid of the box, took out a milky white wrench from it, and gently placed it next to the green wrench.

The pattern engraved on the milky white wrench is exactly the same as the one engraved on the green wrench.

"Tell us about the two experts."

"The wrench I brought is a relic of Zhu Yuanzhang, the founding emperor of the Ming Dynasty, and the inner wall of this wrench also has a note, you take a closer look, these two seal characters are 'Hongwu'"

"Director Peng, do you want to say that this green wrench is also Zhu Yuanzhang's?"

"This wrench is a relic of Emperor Jianwen Zhu Yunwen." Professor Gu said, "You see, these two seal characters are 'Jianwen'. ”

The three of them were a little stunned, they could already confirm that the green wrench in front of them was the heirloom handed down by Ran Ruzhai's ancestor. But they know very little about the situation of Emperor Jianwen Zhu Yunwen.

"The situation is like this: Zhu Yuanzhang originally planned to pass the seat to his eldest son Zhu Biao, but he was not in good health, in the twenty-sixth year of Hongwu, Zhu Biao died young, and four months after Zhu Biao's death, Zhu Yuanzhang named Zhu Biao's son Zhu Yunwen as the emperor's grandson."
