The Dark King

"I have recently improved "Corrosive Acid Mist". On the basis of the current most advanced Polk version of Corrosive Acid Mist, I increased the venom of red fruit leaf juice and crocodile snake. In theory, the corrosion in red fruit leaf juice Sour gas can reconcile the venom of the flower crocodile snake, so as to achieve the effect of strong acid corrosion. If it can be completed, my corrosive acid mist can even corrode metals!Momo said excitedly.

Du Di'an saw his fanatical expression, thinking of his previous shy look, shaking his head in his heart and laughing, saying: "If you want to corrode metals, it is too difficult to rely on the venom in the living body. It is almost impossible. The basic types of the two substances are different. It’s easier to start with the metal itself."

"Start with the metal itself?" Momo wondered.

Du Di An 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, moisture, etc. in the air. The substance falls on the metal and erodes into the metal, so it will corrode the metal. This process can be called'oxidation'."

"Oxidation?" Momo and Jinba and Simo were all confused, a word they had never heard of.

Du Dian knows that they are difficult to understand for a while. After all, the periodic table of the elements has not been made. The existence of oxygen is currently unknown. He can only say: "Under normal circumstances, water will slowly disappear, and so is metal."

Jinba thought thoughtfully: "The water will disappear because it is absorbed by the temperature in the air. Do you mean that the metal will also be absorbed by the temperature? Or is it absorbed by the dust?"

Du Di'an saw him groping to the edge and said, "Water is liquid, so it disappears quickly, and the metal is solid. The disappearance time will be much slower, just like a piece of metal will only rust and rot in a few years. If it is decades, Hundreds of years have passed, and like water, it will rot so badly that after thousands of years, it will even rot to nothing."

Simao nodded while thinking: "Yes, you say that, it is true, so that the dust can corrode the metal, it's amazing."

Momo bowed his head in contemplation and muttered to himself: "If so, dust can corrode metal, dust is mud, and mud is rock. There must be something in the rock that can corrode metal faster..."

Du Dian glanced at him, but he didn't expect him to understand it at all. The most common thing that corrodes metals is naturally not sulfuric acid. Sulfuric acid is extracted from substances such as sulfur and pyrite. The current soil system Sulfuric acid has not yet been produced, and if submitted, it is also a high-level magic item.

"Your observation of everything is very careful." Jimba looked at Du Dean's eyes.

Du Dian smiled slightly and said, "Everything is made by the god of light. This is the enlightenment it gave us."

Jin Ba said, "My teacher often warns us to learn to observe the world a lot, the truth is hidden in every corner of the world, and it stands in front of us, but we don't see through all the illusions of God, we can see through Truth." Speaking of which, I can't help but sigh.

Du Di'an nodded slightly, feeling the same.

Time flies, the night darkens, and the chill grows.

The banquet ended in brilliant lights, and the guests left before the end of the night.

Du Dian, as the host of the banquet, stood at the door and sent the guests back one by one. After the nobles left most of them, they returned to the living room. The rest of the nobles were handed over to Kaili to say goodbye.

"We should go back too." Jimba saw Du Dean come back and stood up.

Du Di'an said: "Do not sit more?"

"No, the teachers are tired too." Jimba smiled at him: "We will talk about it next time when I'm free. I believe you will soon become a senior 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."

Du Di'an laughed: "Okay."

At this time, the two old men sitting and drinking tea also got up and saw the expressions of their three students. They suddenly understood in their hearts. The tall and thin old man on the left said: "We have to go back first. My two students, they will help you."

Du Dilian nodded and thanked.

"I heard that you want to take on the mission of the old ghost of Ibiza? He is from the Thunder system. The research he has done is too dangerous. Maybe one day he will be killed. You should concentrate on your own wood magic." The chunky old man's language is authentic.

Du Di'an nodded: "I know."

Erlao glanced at him, and said nothing more, and left behind surrounded by the three Jinba.

When the other nobles around saw them, they all greeted each other, but the second elder did not glance at them, politely, and left the hall directly, which embarrassed some of the nobles who came forward.

"It's finally over." Carey, who had delivered his guests, returned to the hall and smiled at Du Dean: "Today, two masters, Kleiss and Hunt, came to congratulate you. It was an unexpected joy and elevated your identity. After several levels, although you are currently only an intermediate ambassador, in their hearts, they are no worse than advanced ambassadors."

Du Di'an nodded, this is the influence of the master, only need to play a game, you can improve his worth.

"You have worked hard today," Du Dean said to Carey. "After you are busy, you will be invited to dinner someday."

Carey smiled and said, "OK, I remember this meal."

Du Dian smiled slightly, although Carey's position is personnel management, but in addition to the smooth character, there is a bold and admirable.

At this moment, the guests had been scattered in the hall, and only some servants were left to clean up the garbage on the floor and the wine on the table. Du Dean found Flint and Sandro who were sitting on a sofa, and walked over immediately, saying: "Old Patriarch, I will send you back."

"Okay." Folin said with a smile, knowing Du Di'an had something to tell him.

Du Dean turned back to say goodbye to Carey, then stepped forward and helped Fulin leave the hall. At the moment of the night, the outside was cold like a knife. Du Dian glanced at Flint's thin coat, when he was about to take off his coat and put him on, He hurried to the carriage outside the manor.

Seeing Du Dean's move, Sandro stopped talking, and in the end he silently followed, silently.

"Master," the butler and groom waiting in front of the carriage respectfully said.

"Go back," Fulin ordered.

Du Dean sent him to the car, but the housekeeper and Sandro also entered the second carriage, and drove back to the Castle of Lane together.

It was dark at the moment, and there was no voice in the castle. When Du Dean and others entered the castle, they saw a girl sleeping there in the living room. It was a granddaughter of Fulin, named Lina, who was 14 years old this year. A few years younger than Hutton, lying in the living room sleeping soundly, covered in a thin quilt handed over by the maid.

"Huh?" Fulin looked over.

Aunt Lan, a middle-aged woman who was waiting for Fulin at the side, usually stepped forward and whispered: "Lina, the child must wait for you to come back and fall asleep here, I will wake her up now."

Fulin glanced at the sleeping girl's face and sighed softly. "Let her go back to the room to sleep." After that, he turned upstairs with his cane.

Du Dean helped him and looked back at the girl lying on the sofa. If the information he got from Button and others were correct, the girl was the child of Fulin’s four daughters, who married a grumpy man. The rich and deceased businessman died shortly after giving birth to her daughter. Fulin took her granddaughter back to her to take care of her, but perhaps she did not like it because of her mother.

Aunt Lan awakened Lina on the sofa. The girl opened her sleepy eyes, and when she woke up, she was shocked and immediately looked around. She suddenly saw Du Di'an holding Fulin's back, her lips slightly open, and she wanted to What he said, but was stopped by Aunt Lan, whispered: "Miss, the old man asked you to go back to rest, and the old man was tired."

Lina glanced at her, bit her lip slightly, said nothing, and stood up silently to leave.
