"I have been improving the "corrosive acid mist" recently.
Based on the current most advanced Polk version of corrosive acid mist, I have added red fruit leaf juice and the venom of the crocodile snake.
Theoretically, the corrosion in the red fruit leaf juice The acid gas can reconcile the venom of the crocodile snake to achieve the effect of strong acid corrosion.
If it can be completed, my corrosive acid mist can even corrode metal," Momo said excitedly.
Dudian saw his enthusiastic expression and thought of his previous shy appearance.
He shook his head and smiled bitterly in his heart, and said: "To corrode metal, it is too difficult and almost impossible to corrode metal by relying solely on the venom in the living body.
The basic types of the two substances are different.
If we start from It’s easier to get the metal itself.”
"Start with the metal itself," Momo wondered.
Du Di'an said: "Under normal circumstances, metal will corrode and rust, but it takes time.
However, it is not "time" that corrodes the metal itself, but time allows dust, water, humidity, etc. in the air to corrode.
The substance falls on the metal and erodes into the metal, so it corrodes the metal.
This process can be called oxidation. " "Oxidation" Momo, Jinba, and Simo are all confused.
This is a word they have never heard.
Dudian knew that it was difficult for them to understand for a while.
After all, the periodic table of elements had not been produced yet, and no one knew about the existence of oxygen yet.
He could only say: "Under normal circumstances, water will slowly disappear, and the same goes for metals."
Jinba said thoughtfully: "Water will disappear because it is absorbed by the temperature in the air.
What you mean is that metal will also be absorbed by temperature, or in other words, it will be absorbed by dust."
Dudian saw him groping for the edge and said: "Water is liquid, so it disappears quickly.
Metal is solid, and the disappearing time will be much slower.
Just like a piece of metal will rust and rot after a few years.
If it takes decades, After hundreds of years, it will rot like water and become incomplete.
After a thousand years, it will even rot until nothing is left.”
Xi Mo thought and nodded: "Yes, if you say so, it is indeed true.
Speaking of which, it is 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 soil, soil is rock.
There must be something in the rock that can corrode metal faster."
Dudian glanced at him, but he didn't expect him to know that the most common thing that corrodes metal is naturally sulfuric acid.
Sulfuric acid is extracted from sulfur, pyrite and other substances through dissolution and distillation.
Currently, the soil system The sulfuric acid has not been produced yet.
If it is submitted, it will be considered a high-level magical item.
"You observe everything carefully."
Jinba looked into Dudian's eyes and said.
Dudian smiled slightly and said: "Everything is created by the God of Light.
This is the enlightenment he gives us."
Jinba hummed and said: "My teacher also often warns us to learn to observe the world more.
The truth is hidden in every corner of the world and is standing in front of us.
It's just that we don't have the eyes to see through all illusions."
Truth."
At this point, he couldn't help but sigh.
Dudian nodded slightly, feeling the same.
Time flies, the night is getting darker and the chill is getting thicker.
The banquet ended with brilliant lights, and the guests dispersed before dawn.

As the host of the banquet, Dudian stood at the door and sent the guests back one by one.
After most of the nobles had left, he returned to the living room and left the remaining minor nobles to Kaili to see them off.
"It's time for us to go back."
Jinba stood up and said when he saw Dudian coming back.
Du Di'an said: "Don't sit too much" "No, the teachers are tired too."
Jinba smiled at him and said: "We will talk in detail next time when we have time.
I believe you will soon become a senior divine envoy.
Then I will tell the teacher and let you follow We live in a place where we can discuss some magical issues every day."
Dudian smiled and said: "Okay."
At this time, the two old men who were sitting and drinking tea also stood 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 are going back first.
If you need anything in the future, just ask These two students of mine will help you.”
Dudian nodded his thanks.
"I heard that you want to take on the mission of that old ghost in Ibiza.
He is from the thunder system.
The research he is doing is too dangerous.
He might blow himself up one day.
You should just concentrate on your own wood magic."
The fat old man spoke with sincerity and sincerity.
Dudian nodded and said, "I understand."
The second elder glanced at him, said nothing more, and left surrounded by Jinba and the others.
When other nobles around them saw them, they all came forward to say hello, but the two elders didn't even look at them, and left the hall directly without being polite.
This made some nobles who came up to chat with them extremely embarrassed.
"It's finally over."
After seeing off the guests, Kaili returned to the hall and smiled at Dudian: "Today, two masters, Kress and Hunter, came to congratulate you.
It's really an unexpected surprise and will enhance your status.
You have passed several levels, and although you are currently only an intermediate divine envoy, in their hearts, you are no longer inferior to a high-level divine envoy."
Dudian nodded, this is the influence of the master, just one appearance can increase his worth.
"Thank you for your hard work today."
Dudian said to Kaili, "After I have been busy, I will treat you to dinner another day."
Kaili smiled and said, "Okay, I'll remember this meal."
Dudian smiled slightly.
Although Kaili's position is personnel management, in addition to being tactful, his character also has a boldness that is admirable.
At this moment, all the guests in the hall had dispersed, and only some servants were left sorting out the garbage on the floor and the drinks on the table.
Dudian found Fulin and Sandro who were sitting on a sofa waiting, and immediately walked over and said, "Old man.
Chief, I’ll take you back.”
"Okay."
Fulin said with a smile, knowing that Dudian had something to say to him.
Dudian turned around and said goodbye to Kaili, then stepped forward to help Fulin leave the hall.
It was late at night, and the wind was as cold as a knife outside.
Dudian glanced at Fulin's thin coat, and immediately took off his shirt and put it on him.
Help him rush to the carriage outside the manor.
Sandro saw Dudian's actions and hesitated to speak.
In the end, he didn't say anything and followed silently.

"Sir," the steward and groom waiting in front of the carriage said respectfully.
"Go back."
Fulin ordered.
Dudian sent him to the car, and the housekeeper and Sandro also entered the second carriage and drove back to Lane Castle together.
It was dark now, and there was no one in the castle.
When Dudian and others entered the castle, they saw a girl sleeping there in the living room.
It was one of Fulin's granddaughters, called Lina, who was fourteen years old this year.
A few years younger than Hughton, he was lying in the living room sleeping soundly, covered with a thin quilt handed over by the servant.
"Yeah" Fulin looked over.
Aunt Lan, a middle-aged woman who was waiting nearby and usually waited on Fulin, stepped forward and whispered: "Lina, this child 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 softly, and said, "Let her go back to her room to sleep."
After saying that, he turned around and went upstairs with his cane.
Dudian supported 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 Fulin's fourth daughter, who married a man with a bad temper.
Fulin, a down-and-out wealthy businessman, died shortly after giving birth to his daughter.
Fulin took his granddaughter back to him to take care of him, but he didn't like her, perhaps because of his mother.
Aunt Lan woke up Lina on the sofa.
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.
His lips were slightly opened, wanting to She said something, but Aunt Lan stopped her and whispered: "Miss, I want you to go back and rest.
I am also tired."
Lina glanced at her, bit her lip slightly, said nothing, stood up and left silently
