"I'm currently improving "Corrosive Acid Mist". On the basis of the most advanced Pocket version of Corrosive Acid Mist, I add the venom of the naked leaf juice and the crocodile snake. Theoretically speaking, the corrosive acid gas in the naked leaf juice It can reconcile the venom of the crocodile snake, so as to achieve the effect of strong acid corrosion. If it can be completed, my corrosive acid mist can even corrode metal! Momo said excitedly.
Seeing his fanatical expression, Du Dian thought of his previous shyness, shook his head and smiled bitterly, and said: "If you want to corrode metals, it is too difficult to rely solely on the venom in the organism, and it is almost impossible. The basic types of the two substances are different. It’s easier to get the metal itself.”
"Start with the metal itself?" Momo wondered.
Du Dian said: "Under normal circumstances, metals will also be corroded and rusted, but it takes time. However, it is not "time" that corrodes the metal itself, but time to let dust, moisture, humidity, etc. in the air Substances fall on the metal and erode into the metal, so the metal will be corroded. This process can be called 'oxidation'. "
"Oxidation?" Momo, Jinba, and Ximo were all confused, this was a word they had never heard before.
Du Dian knew that it was difficult for them to understand for a while. After all, the periodic table of elements has not been made, and no one knows the existence of oxygen. He can only say: "Under normal circumstances, water will slowly disappear, and the same is true for metals."
Jinba thought about it: "Water disappears because it is absorbed by the temperature in the air. Do you mean that metal is also absorbed by temperature? Or is it absorbed by dust?"
Seeing him groping to the edge, Du Dian said: "Water is liquid, so it disappears quickly. Metal is solid, and the disappearance time will be much slower, just like a piece of metal will rust and rot after a few years. If it is decades, After a few hundred years, it will rot like water and become incomplete, and after a thousand years, it will even rot to nothing."
Simo nodded while thinking, "That's right, it's true when you say it that way. Speaking of it, it's amazing that dust can corrode metal."
Momo lowered his head and fell into deep thought, muttering to himself: "If this is the case, dust can corrode metal, dust is dirt, dirt is rock, and there must be something in the rock that can corrode metal faster..."
Du Dian glanced at him, but he didn't expect him to see through it at all. The most common thing that corrodes metals is naturally sulfuric acid, and sulfuric acid is extracted from sulfur and pyrite through dissolution and distillation. Sulfuric acid has not been produced yet, if it is submitted, it is also a high-level magical item.
"You observe everything very carefully." Kimba looked into Du Dian's eyes and said.
Du Dian smiled slightly and said: "Everything is created by the God of Light. This is the enlightenment it gave us."
Jinba hummed, and said: "My teacher often tells us to learn to observe the world more. The truth is hidden in every corner of the world, and it stands in front of us. It's just that we don't have the divine eye to see through all illusions. We can see through it." Truth." Having said this, he couldn't help sighing.
Du Dian nodded slightly, feeling the same way.
Time flies, the night is getting darker, and the chill is getting stronger.
The banquet ended in brilliant lights, and the guests left before dawn.
As the host of the banquet, Du Dian stood at the door and sent the guests back one by one. After the nobles left for most of the time, they returned to the living room. The rest of the little nobles were handed over to Kaili to see them off.
"It's time for us to go back." Seeing Du Dian coming back, Jinba got up and said.
Du Dian said: "Don't sit down?"
"No, the teachers are tired too." Jinba smiled at him, "Let's talk in detail next time when we have free time. I believe you will soon become a high-level envoy. Then I will tell the teacher that you will be with me." We live in one place, and we can discuss some divine arts every day."
Du Dian smiled and said, "Okay."
At this time, the two old men who were resting and drinking tea also got up and came over. Seeing the expressions of their three students, they suddenly understood. The tall and thin old man on the left said: "We will go back first. My two students, they will help you."
Du Dian nodded his thanks.
"I heard that you want to take on the task of that old ghost in Ibiza? He is from the Lightning Department, and the research he is doing is too dangerous. He might blow himself up one day. You should concentrate on your wood-type magical arts." The chunky old man spoke earnestly and authentically.
Du Dian nodded and said, "I see."
The second elder glanced at him, said nothing more, and left surrounded by the three of Jin Ba.
When the other nobles around saw them, they all stepped forward to say hello, but the second elder didn't even look at them, and they left the hall without being polite, which made some nobles who approached them very embarrassed.
"It's finally over." Carey returned to the hall after seeing off the guests, and smiled at Du Dian: "Today, two masters, Kles and Hunter, came to congratulate you. Although you are only an intermediate-level envoy, in their hearts, you are no less than a high-level envoy."
Du Dian nodded, this is the influence of the master, and he can increase his worth just by playing a game.
"Thank you for your hard work today." Du Dian said to Kaili, "After busy work, I will treat you to dinner another day."
Carey smiled and said, "Okay, I will remember this meal."
Du Dian smiled slightly. Although Kaili's position is personnel management, besides being smooth, he also has a forthright character, which is appreciated.
At this moment, all the guests were gone in the hall, and only some servants were left to sort out the garbage on the floor and the drinks on the table. Du Dian found Fulin and Sandro who were waiting on a sofa, and walked over immediately, saying: "Old man Patriarch, let me take you back."
"Okay." Fulin said with a smile, knowing that Du Dian had something to tell him.
Du Dian turned back to say goodbye to Kaili, and stepped forward to help Fulin leave the hall. At this moment, it was late at night, and the cold wind outside was like a knife. Du Dian took a look at Fulin's thin coat, and immediately took off his coat and put it on him. Help him to drive to the carriage outside the manor.
Seeing Du Dian's actions, Sandro hesitated to speak, but in the end he didn't say anything, and followed silently.
"Master." The housekeeper and groom who were waiting in front of the carriage said respectfully.
"Go back." Flynn ordered.
Du Dian sent him to the car, and the housekeeper and Sandro also got into the second carriage and drove back to Ryan Castle together.
At this moment, the night was dark, and there was no one in the castle. When Du Dian and others entered the castle, they saw a girl sleeping there in the living room. It was Fulin's granddaughter, Lena, who was fourteen years old this year. A few years younger than Hughton, he lay in the living room and slept soundly, covered with a thin quilt handed over by the servant.
"Huh?" Flynn looked over.
Aunt Lan, a middle-aged woman who usually waits on Fulin by the side, stepped forward and whispered: "This child Lina insists on waiting for you to come back. She fell asleep here. I will wake her up now."
Fulin glanced at the sleeping girl's face, sighed lightly, and said, "Let her go back to her room to sleep." After speaking, he turned around and went upstairs with his cane.
Du Dian helped him, and looked back at the girl lying on the sofa. If the information he got from Barton and others was correct, this girl was the child of Flynn's fourth daughter. This fourth daughter married a grumpy The down-and-out rich businessman died shortly after giving birth to his daughter. Fulin took his granddaughter back to him to take care of him, but perhaps because of his mother, he didn't like her.
Aunt Lan woke up Lina on the sofa, and the girl opened her sleepy eyes. She was startled as soon as she woke up. She immediately looked around and saw the back of Du Dian helping Fulin go upstairs, her lips parted slightly, wanting to What did you say, but was stopped by Aunt Lan, and said in a low voice: "Miss, the master told you to go back to rest, the master is also tired."
Lina glanced at her, bit her lips slightly, said nothing, got up and left silently.
