Feng Yu Jiu Tian

Another rare sunny day in the early winter, Feng Ming and Lu Dan sat face to face in the magnificent room.

In this matter, no matter how much resentment the two people have, they are now a grasshopper on the line. Death is a pair of life or a pair. Feng Ming also knows that ninety-nine percent of the old goddesses in the priestly house are not humans psychologically. No matter how bad Lu Dan is, at least they are the only close allies.

Based on the principle of vitality, Fengming couldn't even consider that his knowledge could only be used in the construction of Xilei. He told the story in his stomach for hours, drank five pots of hot tea, and his mouth was still dry. As if it would crack, and finally looked at Lu Dan with anticipation, and asked carefully: "Did the National Teacher get enlightenment from these beautiful myths, and think of any way to make miracles appear?"

Lu Dan shook his head and said, "The story told by Ming Ming is incredible. What can be enlightened?"

Fengming was also in a bad mood, and immediately blew her nose. He can come up with such a complicated strategy to turn himself around Rong Tian, ​​how can he not think of a way to deal with a few old goddesses whose teeth are about to lose light?

Turning around to look out the window, the setting sun is as dreamy as adding a bit of warmth to the hunting wind, but it also shows that their life is getting shorter and shorter.

The self-cultivation teacher said: People's sincerity can move anyone. Does this mean that he should sincerely admit to the chief priest at this moment that he was just a slippery moment?

Feng Ming sighed quietly, teacher, teacher, how can you know how dark the struggle for rights is. As a student, I have a lot of sincerity. Why is everyone thinking about my life? Ben Mingwang never hurt the truth.

Sighing two or three times, a red fruit appeared under the eyelids.

Ludan is Ludan in the end. After a major blow in the morning, he has replied, his face calmly holding the fruit and saying, "Life and death are dominated by the gods, Ming Wang is useless. Eat a fruit, this whole body is red and gorgeous The fruit is specially given to the nobles by the gods, it is delicious and juicy, and it nourishes the body. "

"Fruit is fruit, and everyone can eat it. What has to do with the gods?" Feng Ming took the fruit.

Lu Dan shook his head disapprovingly: "The King Ming is wrong, the gods dominate everything in the world, and they will reward good things to the honorable ones. The royal family is controlled by the gods to master the kingship. Otherwise, what is the difference between the nobles and the slaves? Speaking of nobles and slaves, even the fresh fruits are taken care of by the gods. Fruits loved by the gods will be beautiful and red, and fruits that are not loved by the gods are blue and white and ugly. That is the food that the lower class people eat. "

The fruit really was very sweet. Feng Mingyu chewed the fruit on his hand and wiped his mouth before he had time to answer: "What matters about the royal family is too complicated. That is the stuff of politics and economics. There are many new terms. I You did n’t understand it. As for the fruit, hey, let me tell you, it is the problem of the production of red pigment under sunlight. This is chemistry, and you do n’t understand it. Yeah, chemistry ... ”

Fengming didn't know what to think, and when he was halfway there, he suddenly paused and murmured with straight eyes: "Chemistry, why didn't I think of chemistry?" He jumped up and yelled, "Haha, I'm really a genius. Why didn't you think of a chemical strategy? "His face excitedly said to Lu Dan:" Guo Shi, your holy lake, the lake seems blue, right? "

Lu Dan nodded doubtfully: "It is indeed blue. The sacred lake is crystal clear. The color is different from other lakes. It is a **** ..."

"What god? Forget it, I said to you that you don't understand chemical elements. Let me think about it quietly." Feng Ming sat down, searching the brain and remembering what the chemistry teacher had taught.

Blue lake? It seems that I have read a report somewhere before. The volcano is rich in minerals, and sometimes there are lakes containing metal ions, which make the lakes have a strange color.

One of these ions is the beautiful blue lake containing copper sulfate.

Copper sulfate is a compound that was learned in middle school chemistry. Feng Ming prefers to experiment. He clearly remembers that the low-concentration copper sulfate solution is blue. If the concentration is high, the copper sulfate solution will Blue-green.

It's just ... with his ordinary student's chemistry level, can he be certain that the Tiandi Lake contains copper sulfate? In case of a mistake, wouldn't he be the first chemist in the world to lose his life due to the failure of a great chemical experiment? Although great enough, I don't want to thank you.

Lu Dan smirked for a while, sighed for a while, frowned and gritted his teeth, and took a nap for a while. Although he didn't know what he was thinking, he also understood that it must be related to the lives of the two. Question: "I don't know if Ming Wang thought of it ..."

"Gamble, bet!" Feng Ming roared suddenly, and re-taped her palms on the table, shaking the teapot and cups. Feng Ming's heart was savage, his eyes glared, and his teeth grinded: "Anyway, a dead horse is treated as a living horse doctor, and I will treat him as copper sulfate."

Turning around and seeing Zheng Lu staring at him quietly, Feng Ming laughed, and when he was relaxed, he was also intimate with Lu Dan, and patted him kindly on his shoulder: "Luda ​​Dan is a beautiful lady, I have already thought of miracles But I would like to ask you to help me do two things. First, I need sodium sulfate, oh, sodium sulfate is easy to deteriorate, it is not easy to find. So, I want sulfur compounds, as long as there are sulfur ions. No. Second, I want you to order someone to secretly put a lot of this stuff into Tiandi Lake. Hahaha, in this way, miracles will appear, and the priests who keep it will be stunned and scared to lie on the ground and call the gods for their lives. "

The principle is actually very simple. When sulfur ions meet copper ions, copper sulfide is produced, which is a black precipitate.

As long as a large amount of sulfide and copper sulfate react, the sacred lake of the priests will change from the crystal blue and lovely blue to the horrible and ugly black one, and then propagate it, saying that they are because they have sinned against the sanctuary of God Incurring the punishment of the gods, they worry that they will not treat you with respect and respect.

Thinking of the pride, Feng Ming secretly deered Lu Dan. Once the priest's house regarded himself as a guest, even Lu Dan, a master, would not dare to embarrass him easily.

As for the possibility that the minerals in the lake may not be copper sulfate, Fengming's brain automatically ignores filtering. At the moment of crisis, we can't always let ourselves down.

Lu Dan frowned for a while on Fengming's modern chemical terminology, frowning: "What is the sulfuric acid, sulfur compound, sulfur ion ... just what Mingwang just said?"

It's really not easy to explain this problem, and it's impossible to show Lu Dan the element map.

Fengming thought about it and asked, "Is there a volcano near Dongfan?"

This time, Lu Dan finally understood what he meant, and nodded: "Every east is a country of volcanoes, there are more than a hundred volcanoes, large and small, and even this Tiandi Mountain where our heaven and earth palace relies, more than 200 years ago. The fire broke out. The holy lake only appeared after the fire broke out, and the ring of heaven and earth was also mined. Here is the gift of the gods to my royal family ... "

"Wonderful! Wonderful!" Fengming already laughed before waiting for Lu Dan to say, "It turns out that here is a volcano, and sulfide is the most near the volcano. Well, it's really difficult for you guys who don't understand chemistry to find sulfide. Although I was recovering from a serious illness, I was careful not to be lazy. Let ’s go and collect the good things that opened the eyes of the old ladies. It does n’t have to be too far to be near this volcano. Hehe, with these, what offerings All the holy lakes in the teacher's college give me a step back. "

There was another embarrassing silence in the room.

For a long time, Lu Dan smiled helplessly: "Ming Ming, we are both prisoners, don't mention the heaven and earth palace, even this door can't get out." He looked at Feng Ming's stiff smile, and finally , Plus a sentence, "And the people who come to serve me can't leave here. We can't even pass on the message now."

Feng Ming fluttered, his eyes dull and fell to the bed.

Rong Tian, ​​even if you get Mei Ji out this time, as long as you can save me, I will forgive you.

I will never see you again ...
