Vol 3 Chapter 249: : Lena

I have recently improved the corrosion of acid mist, based on the current state-of-the-art Polk version of corrosive acid mist, increasing the venom of red fruit juice and crocodile snake. In theory, the corrosive acid in the juice of red fruit leaves. It can reconcile the venom of the crocodile snake to achieve strong acid corrosion. If it can be done, my corrosive acid mist can even corrode the metal!" Momo said excitedly. network
Du Di'an saw his fanatical expression, thought of his previous appearance, and smiled in his heart. He said: "If you want to corrode metal, it is almost impossible 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 for the metal itself to start.

"Starting with the metal itself?" Momo wondered.
Du Di'an said: "Under normal conditions, the metal will also be corroded and rusted, but it takes time. However, it is not time to corrode the metal itself, but time to let the dust, moisture, moisture and other substances in the air fall. On the metal, it erodes into the metal, so it will corrode the metal. This process can be called 'oxidation'."
"Oxidation?" Momo and Jinba and Ximo are all confused. This is a word they have never heard before.
Du Di'an knew that they were difficult to understand at the moment. After all, the periodic table of elements was not made. The existence of oxygen is still unknown. He can only say: "Under normal conditions, water will slowly disappear, and so will metal."
Jinba thought: "Water will disappear by the temperature in the air. Do you mean that the metal will 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. The metal is solid. The time of disappearing will be much slower. Just like a piece of metal will rust and rot in a few years. If it is for decades, In the past few hundred years, it will be like water, and it will be rotted. After a thousand years, it will even rot and there will be nothing left."
West Momo thought and nodded: "Yes, you said so, it is true. So, dust can actually corrode metal, it's amazing."
Momo bowed his head and meditated, muttering to himself: "If this is the case, dust can corrode metals, dust is mud, mud is rock, there must be something in the rock that can corrode metals faster."
Du Dian glanced at him. He didn't expect him to pass through. He said that the most common thing to corrode metals is natural non-sulfuric acid. Sulfuric acid is extracted from sulfur and pyrite by dissolution and distillation. Sulfuric acid has not yet been produced, and if submitted, it is also a high-level magical item.
"You are very careful about the observation of everything." Kimba looked at Dudian's eyes.
Du Di'an smiled and said: "All things are created by the of light. This is the enlightenment it gives us."
Jin Ba sighed and said: "My teacher also often warns us to learn to observe the world. The truth is hidden in every corner of the world, and it is standing in front of us. It is just that we have not seen the eyes of all illusions and can see through. Truth." Speaking here, I can't help but sigh.
Du Dian nodded slightly and shared the same feeling.
Time flies, the night is getting darker, and the chill is thicker.
The banquet ended in the glory of the lights, and the guests left before the night donation.
As the owner 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 other nobles handed over to Kaili to bid farewell.
"We should go back too." Jinba saw Du Di'an come back and got up.
Du Di'an said: "Don't sit still?"
"No, the teachers are tired." Jinba smiled at him: "We will talk more about it next time. I believe that you will soon become a senior god. When I tell the teacher, let you follow. We live in a place where we can explore some magical problems every day."
Du Di'an smiled and said, "Okay."
At this time, the two old people sitting and drinking tea also got up and saw the expressions of their three students. They suddenly understood each other. The old and thin old man on the left said: "We will go back first. What will happen in the future? I am two students, they will help you."
Du Dian nodded and thanked.
"I heard that you want to take the task of the old ghost of Ibiza? He is a thunder, and the research is too dangerous. Maybe you will kill yourself one day, and you still concentrate on doing your own wood magic." The short-skinned old man has a long-lasting heart.
Dudian nodded: "I know."
Er Lao looked at him and said nothing more. He left under the crowd of Jinba.
The other aristocrats around them saw them, and they all greeted each other. But the two old ladies didn't take a look at them. They were polite and polite. They left the hall directly, which made some nobles who were rushing forward stunned.
"It's finally over." Kerry, who had finished the guest, returned to the hall and smiled at Du Di'an: "Today, there are two masters of Chryss and Hunter who come to congratulate you. It is a surprise, and your identity is raised. A few orders, although you are currently only a middle-level god, but in their hearts, it is no less inferior to the senior god."
Dudian nodded, this is the influence of the master, just a game, can increase his value.
"It's hard for you today." Du Di'an said to Kaili. "After taking a break, please ask for dinner."
Carey smiled and said, "Oh, I remember this meal."
Du Di'an smiled a little, although Kaili's position is personnel management, but in addition to the sleek personality, there is a bold and enjoyable.
At the moment, the guests in the hall have been scattered, leaving only some maids to sort out the and table drinks on the ground. Du Dian found the forints and Sandu who were sitting on a sand waiting, and immediately went over and said: "Old Patriarch, I will send you back."
"Good." Fulin smiled and knew that Du Di'an had something to say to him.
Du Di'an turned back and said goodbye to Kaili, and then he stepped forward to help Fulin leave the hall. At this moment, the night was cold and the wind was like a knife. Du Dian glanced at the thin coat of Fulin, and when he took off his coat, he put it on him. Hold him to the carriage outside the manor.
Sandru saw Dudian's move, and he stopped talking. He finally did not say anything and silently followed.
"Master." The butler and the groom waiting in front of the carriage respectfully.
"Go back," said Fulin.
Dudian sent him on the bus, butler and Sander also entered the second carriage and drove back to the castle of Lane.
At this moment, the night is deep, and there is no one in the old castle. When Du Di'an and others enter the castle, they see a girl sleeping there in the living room. It is a granddaughter of Fulin, called Lina, 14 years old this year. Than Hughton's slack, lying in the living room and sleeping, covered with a thin quilt handed by the maid.
"Hmm?" Forint looked at it.
Waiting for the middle-aged woman who is waiting for Fulin in the usual time, Lancome even whispered to the front: "Lena, this child has to wait for you to come back, fell asleep here, I am going to wake her up now."
Fulin glanced at the sleeping girl's face and sighed softly. "Let her go back to the room to sleep." Then he turned to the floor with a cane.
Du Di'an helped him and looked back at the girl lying on the sand. If the information he got from Barton and others was correct, the girl was the child of the fourth daughter of Forint, who married a grumpy temper. The fallen merchants, who gave birth to their daughters soon passed away, and Fulin took the granddaughter back to his side, but perhaps because of his mother, he did not like it.
Lancome wakes Lina on the sand, and the girl opens her eyes. When she wakes up, she wakes up and immediately looks around. She immediately sees Du Di'an holding the back of Fulin upstairs, lips slightly, wanting What to say, but was stopped by Lancome, whispered: "Show, the master let you go back to rest, the master is tired."
Lena glanced at her, biting her lip slightly, saying nothing, and quietly got up and left.
