Chapter 249: Lena

"I am improving the "Corrosive Acid Mist" recently. On the basis of the most advanced Polk version of the Corrosive Acid Mist, I have added the venom of the red fruit leaf juice and the crocodile snake. In theory, the corrosion in the red fruit leaf juice The acid gas can reconcile the venom of the crocodile snake, so as to achieve the effect of strong acid corrosion. If it can be done, my corrosion acid mist can even corrode metal! "Momo said excitedly.

Du Dian saw his fanatical expression, thought of his previous shy appearance, shook his head and smiled bitterly in his heart, and said: "If you want to corrode metal, 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, if you want to corrode metals, it is almost impossible. The metal itself is easier to get started with.”

"Start with the metal itself?" Momo wondered.

Du Di'an said: "Under normal circumstances, metal will also corrode and rust, but it takes time. However, it is not "time" that corrodes metal itself, but time makes 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, 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 had not been made, and no one knew about the existence of oxygen. He could only say: "Under normal circumstances, water will slowly disappear, and so will metal."

Jinba thought thoughtfully: "The water disappears because it is absorbed by the temperature in the air. You mean, the metal is also absorbed by the temperature? Or, is it absorbed by the dust?"

Seeing him groping to the edge, Du Di'an 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 is decades, Hundreds of years have passed, and it will rot into pieces like water, and after thousands of years, it will even rot to the point where nothing remains."

While thinking about it, Ximo nodded and said, "Yes, you said that, it is true, so 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 mud, mud is rock, there must be something in the rock, which can corrode metal faster..."

Du Di'an glanced at him, but he didn't expect him to see through at one point. To say that 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, and if it is submitted, it is also a high-level divine art item.

"You observe everything very carefully." Jinba looked into Du Dian's eyes and said.

Du Di'an smiled slightly and said: "Everything is created by the God of Light,

This is what it inspires us. "

Jinba snorted and said: "My teacher also often warns us to learn to observe the world a lot, the truth is hidden in every corner of the world, and it is standing in front of us, but we don't have the divine eye to see through all illusions. The truth." Speaking of this, he couldn't help sighing.

Du Di'an nodded slightly, feeling the same.

Time flies, the night is getting darker, and the cold is thicker.

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

As the host of the banquet, Du Di'an stood at the door and sent the guests back one by one. After the nobles left most of the time, they returned to the living room, and the rest of the small nobles were handed over to Kaili to see them off.

"It's time for us to go back too." Jinba got up and said when Du Dian came back.

Du Di'an said: "Don't sit and sit?"

"No, the teachers are tired too." Jinba smiled at him: "Next time we have time, let's talk in detail, I believe you will soon become a high-level envoy, then I will tell the teacher, let you follow We live in one place, and we can discuss some magical issues every day."

Du Dian smiled: "Okay."

At this time, the two old men who were sitting and drinking tea also got up and saw the expressions of their three students. They suddenly understood, the tall and thin old man on the left said: "We will go back first, if you have anything in the future, just look for it. My two students, they will help you."

Du Di'an nodded and thanked.

"I heard that you want to take the task of that old ghost in Ibiza? He is from the Thunder Department, and the research he does is too dangerous. Maybe one day he will blow up himself. You should concentrate on your own wood-based magic." The chunky old man spoke earnestly and earnestly.

Du Dian nodded and said, "I see."

The second old man glanced at him and said nothing more, and left surrounded by the three of Jinba.

When the other nobles around saw them, they all stepped forward to say hello, but the two elders didn't even look at them, and left the hall without being polite.

"It's finally over." Carey returned to the hall after sending the guests, and smiled to Du Dian: "Today, two masters, Chris and Hunter, came to congratulate you. It's an unexpected joy, and it raises your status. After several steps, although you are currently only an intermediate divine envoy, in their hearts, you are no longer inferior to a high-level divine envoy."

Du Di'an nodded, this is the influence of the master, and he can increase his worth just by showing up.

"It's been hard for you today." Du Di'an said to Kaili, "After the busy work, I will invite you to dinner another day."

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

Du Di'an smiled slightly. Although Carey's position is personnel management, in addition to being smooth, there is also a boldness in his character, which is appreciated.

At this moment, all the guests in the hall were scattered, and only some servants were left to sort out the garbage on the floor and the drinks on the table. Du Di'an found Fulin and Sandro who were waiting on a sofa, and immediately walked over, saying: "Old Patriarch, I'll take you back."

"Okay." Fulin said with a smile, knowing that Du Dian had something to tell him.

Du Di'an turned around and said goodbye to Carey, then stepped forward and helped Fulin to leave the hall. At this moment, it was late at night and the wind was cold outside. Du Di'an glanced at Fulin's thin coat, and immediately took off his shirt and put it on him. Help him to the carriage outside the manor.

Sandro saw Du Dian's actions and hesitated, but in the end he didn't say anything and followed silently.

"Master." The butler and groom who were waiting in front of the carriage said respectfully.

"Go back." Flynn ordered.

Du Di'an sent him into the car, and the butler and Sandro also entered the second carriage and drove back to Lane Castle together.

It was dark at this moment, and there was no sound in the castle. When Du Di'an 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 fourteen years old this year. A few years younger than Hutton, he was sleeping soundly in the living room, covered with a thin quilt handed over by the servant.

"Huh?" Flynn looked over.

Aunt Lan, a middle-aged woman who usually waits for Fulin, stepped forward and whispered, "Lina, this child has to wait 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 the room to sleep." After speaking, he turned upstairs with a cane.

Du Di'an 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 short-tempered girl. The poor and wealthy businessman died shortly after giving birth to his daughter. Fulin took his granddaughter back to his side to take care of him, but perhaps because of his mother, he did not 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 looked around immediately, and suddenly saw Du Dian's back supporting Fulin upstairs, her lips were slightly open, she wanted to What to say, but Aunt Lan stopped her and whispered: "Miss, the master told you to go back to rest, the master is also tired."

Lina glanced at her, bit her lip slightly, said nothing, and silently got up and left. (To be continued.)
