Chapter 823 Shu Body Poison Way ([-])
But it has been a long time, and no one has mentioned this ancient traffic artery again.

Gu Yunzhi, who had been listening quietly all this time, only felt that what he had learned before, in front of Xu Qingru at this moment, was nothing but pale words that had lost their color, leaving only black and white.

Even he couldn't sit still, and asked Xu Qingru: "Even if Huiqing entered the Central Plains through the Shushen Poison Road, what does that have to do with the fact that this jade pot must have been produced in the Zhengde period?"

Xu Qingru looked at Gu Yunzhi, her expression became softer, and she said with a smile, "Unfortunately, during the Zhengde period, a big event happened in Yunnan."

"What the hell is the big deal!"

There are already careless elders in the lower class who have started to scold their mothers.

Xu Qingru blinked his eyes and said: "The county annals of the Dali area recorded that in May of the ninth year of Zhengde, Dali, Yunnan was hit by an earthquake, and the Dali Qianxun Pagoda was cracked by more than two feet, and it was shaped like a broken bamboo. "Zhengde Shilu" records that in the tenth year of Zhengde, An earthquake occurred in the Yongsheng area not far from Dali. "It lasted for more than a month, the black air was like fog, and the ground cracked and the water gushed." Thousands of people were killed or injured. Both Dali and Yongsheng are places that must pass through the poisonous road of Shu .”

"!!"

Gu Yunzhi was extremely surprised. He seemed to have guessed how Xu Qingru connected the two.

The people present were also very surprised. They never expected that Xu Qingru, who came from the Southern School, could also be familiar with the documents and materials.

Gu Yunzhi's eyes were full of admiration and admiration, and he asked her: "The Dali earthquake had an impact on Huiqing who entered the Central Plains, and this impact is reflected in this blue and white jade pot spring vase, right? "

When Gu Yunzhi asked this question, he had an answer himself.

Yes, that's how it is, Xu Qingru must have found clues on the blue and white porcelain vase, and thus determined that the blue and white porcelain vase was an object from the Zhengde period of the Ming Dynasty.

Xu Qingru nodded: "Yes, because of the Dali earthquake that year, Huiqing could not be delivered to the Central Plains smoothly, so I thought of a way at that time. The so-called green material is actually refined cobalt ore, and a large number of cobalt ore are distributed in Yunnan. So at that time, I thought of a way to use the local cobalt mines in Yunnan to extract green materials."

"There are some elements such as iron and manganese in the ore of cobalt ore. After refining, the smaller the ratio of iron and manganese, the closer it is to refined cobalt ore. The cobalt ore produced in our country has high manganese content and high iron content. Low, while the cobalt ore produced in West Asia has low manganese content and high iron content. Blue and white with low iron content, the color presented is blue with a gray tone."

"The blue and white material used in this jade pot spring bottle is actually a mixture of Huiqing imported from West Asia and the green material extracted from the cobalt mine in Yunnan. Therefore, if you look carefully, there is a gray tone in the blue color."

Xu Qingru explained it seriously but lightly, with clear words.

Gu Yunzhi smiled: "Master Xu, I believe that no one present, except you, can see through 'careful inspection' that the green material with low iron content mixed in the blue and white, this color Surprised, too subtle."

When Gu Yunzhi said this, he publicly admitted that he was indeed not as good as Xu Qingru.

To be precise, it should be that the other people present were not so clear.

Xu Qingru also responded to him with a smile: "Perhaps, Master Gu just needs a little more time to make a final judgment."

Gu Yunzhi was noncommittal, turned around and looked at the people sitting in the venue, and said, "I, Gu Yunzhi, lost to Xu Qingru today, and I am convinced."
