"Simple?" Xing Qianqiu was slightly stunned.

He knew that Duan Ming was extraordinary, but they had been checking things for several days without clues, and Duan Ming knew the result at a glance?

"Come with me." Duan Ming smiled, didn't explain, and came directly to the kitchen with Xing Qianqiu.

It is very troublesome to do a lot of things in this world, after all, there are no professional chemical instruments in this world.

Therefore, Duan Ming had only been so surprised that the Immortal Sect could make such an extremely high chemical substance as "dry ice" before.

Duan Ming worked in the kitchen for a long time before he built a "structure" similar to a small kiln, and then carefully took out the items scraped from the Great Buddha from his arms and put them inside this "small kiln".

Then a fire was lit, and the fierce fire enveloped the fragments in an instant.

A moment later, under the burning of the raging fire, the black fragments turned red little by little!

"How? Amazing no? Duan Ming had a smile on his face, looked up at Xing Qianqiu and said, "This thing is called ......"

"Copper!" However, Xing Qianqiu said directly.

"Ahem......" Duan Ming choked on Xing Qianqiu's words, and the pride just now was swept away.

At this time, Duan Ming remembered that this world also has smelting technology, although compared to modern society, it is like primitive people, but it does exist.

Even iron ore, copper ore and other items are one of the most important strategic materials in the world.

Therefore, it is very normal for Xing Qianqiu to know copper and understand some changes in copper.

"Mr. Duan, do you mean that the top of this golden Buddha is copper?" Xing Qianqiu glanced at Duan Ming, although he didn't understand why Duan Ming looked like he had eaten a fly, but he was amazed in his heart at the speed of Duan Ming's thoughts.

Even if they had been here for so long, they had never thought of associating the blackening of the Golden Buddha with copper.

"That's right." Duan Ming sighed and nodded: "There is something called oxygen in our air, and copper will react with oxygen to become copper oxide, and copper oxide is black. ”

"Well, I've heard that copper ore will turn black if left for too long, but I've never heard of so-called oxygen, what is it?" Xing Qianqiu wondered.

"Everything in the world comes in a thousand forms. Some are vast, and even the territory of Daqi is only as inscrutable as dust in its eyes; Some are so small that even a speck of dust is as difficult to see in their eyes as the sun. Duan Ming explained: "There is an end to manpower, and there is an end to vision. Just like this grain of copper, it is also composed of countless finer 'copper'. ”

"Hmm." Although Xing Qianqiu couldn't fully understand Duan Ming's words, he could roughly understand Duan Ming's meaning.

"There is an end to manpower, and there is an end to vision." Duan Ming said: "The so-called oxygen is something that people can't see with their eyes. ”

"I see." Xing Qianqiu nodded: "What Mr. Duan means is that the reason why copper turns black is because of this thing called 'oxygen', right?" ”

"That's right." Duan Ming nodded.

"But I've also heard that copper will turn black after being left outside for a long time, but that day no monk found that the golden Buddha has a tendency to turn black, just over an hour, how could such a big golden Buddha suddenly turn completely black?" Xing Qianqiu said suspiciously.

"High temperatures." Duan Ming explained: "The oxidation of copper is slow, but in the case of high temperatures, the rate of oxidation will be exacerbated! ”

"High temperatures? Blaze! Xing Qianqiu's eyes lit up.

"That's right." Duan Ming nodded: "It's that fire!" Copper, under the high temperature generated by the fire, turned into copper oxide and turned black, that is, the fragments just now. Copper oxide and carbon go through high temperatures again and turn back to copper, so they turn red again. ”

"But that's not right, the copper is red, and the Buddha wasn't red before that fire...... "Xing Qianqiu's eyes narrowed, and he pondered: "Perhaps, I should investigate it carefully." ”

"That's right." Duan Ming nodded.

Then Duan Ming and Xing Qianqiu left the kitchen, and Xing Qianqiu went to investigate the matter about the Golden Buddha.

Duan Ming went directly to Xing Qianqiu's room and looked through the clues that Xing Qianqiu had recently collected, including the information of the monks in the temple.

The more Duan Ming looked at it, the more frowning he became, the word "Sanskrit" in this Fanxing Temple means "pure, noble, and admirable behavior", which is taken from the "Dharma Sentence Sutra", namely:

To disturb one's own body, to be merciful, and to be able to endure anger is for the Brahman.

Sincerity and peace, no insect words, no ignorance of the other, is called Brahmanism.

Vertical arch inaction, do not harm sentient beings, do not worry, is to do Brahmanism.

There are many monks in the temple, there are 321 monks in the whole temple, in addition to the abbot of Xuanbei, there are three high monks in Xuanjing, Xuanjing, who are in charge of the size of the temple.

Below the Xuanzi generation is the pure character generation, especially the pure law and pure heart.

Under the net children is the French generation, and there is no particularly outstanding person among the French generation.

The next step is the Ming character generation, which is a junior, mostly seven or eight years old monks.

Just as Duan Ming was checking the specific information, there was a knock on the door.

"Please come in." Duan Ming frowned, it was getting late at the moment, who would come to find Xing Qianqiu at this time?

"Squeak ......" The door was slowly pushed open, and a monk who looked very burly walked in, and he was slightly stunned when he saw Duan Ming sitting in the room.

A little earlier, he saw Duan Ming and Xing Qianqiu walking in the temple together, but he never thought that he was here at this moment.

"Mr. Duan." At this moment, a Spiegel official walked in from outside the door and clenched his fists slightly at Duan Ming: "This is the pure Dharma monk of Fanxing Temple, and he said that he had something to tell the criminal commander." Before leaving, the commander said that you can decide everything here, so his subordinates let it in on their own initiative. ”

"It's fine." Duan Ming shook his head, then looked at the monk called the Pure Dharma: "Is there anything wrong with you?" ”

"This, the donor can really make decisions for the criminal commander?" Jingfa looked at Duan Ming, hesitated for a moment and said.

"It's nature." Duan Ming nodded: "Can the people of the Spiegel Division still lie to you?" ”

"Good!" Jingfa looked left and right, hesitated for a moment and said, "The little monk knows what you are investigating today, and the little monk has something to tell you!" ”

"Oh?" Duan Ming's eyes narrowed slightly: "Please speak." ”

"Well...... Jingfa gritted his teeth and said, "Maybe the donor doesn't believe it, on the day of the fire, the little monk saw the Red Lotus Holy Mother!" ”
