"I have recently improved corrosive acidic mist. I have added red fruit and venom of crocodile snake. Theoretically to red fruit is the best choice to reconcile the poison of crocodile snake and achieve strong level of corrosion. If I complete the project then the corrosion of metal would be possible!" Momo excitedly said.
There was a smile on Dudian's face. He saw Momo's frantic expression which was opposite to his normal shy appearance.: "The venom won't be enough to corrode the metal. Its almost impossible to do it with two different substances. It would be good if you start from metal itself."
"From the metal itself?" Momo was puzzled.
Dudian said: "Under normal circumstances the metal will corrode and rust. But it takes time. However its not about the corrosion of the metal itself but the time for moisture, dust and so on to affect the metal's erosion. In short the process of erosion of the metal can be called 'oxidization'."
"Ox-what?" Momo, Kim and Jin were confused as they had never heard of the word.
Dudian knew that it was very hard for them to understand. After all the periodic table has not been produced yet. They were not aware of the presence of oxygen let talk about oxidization. Dudian said.: "Normally the water slowly disappears the same applies to the metal."
Kim thoughtfully said.: "The water is absorbed by the temperature in the air and disappears. What do you mean? The metal will be absorbed by temperature? Or will it be absorbed by the dust?"
Dudian saw that she touched the edge of knowledge.: "The water is in liquid state so it disappears quickly. However the metal is solid. It will take much slower for it to disappear. For example in few years it will rust and rot. In a decade or hundred years it will turn into liquid state. But it would be incomplete. So after a thousand years that rotten state wouldn't be left."
Jin nodded and said.: "Yes. So to speak the dust can even corrode the metal. It is amazing in a sense."
Momo bowed his head as he contemplated on issue. He muttered.: "If it is so and the dust can corrode the metal... The dust is from soil and soil is made of rocks. The rock must have something to be able to corrode the metal."
Dudian looked at him but didn't continue to tell that the most common thing to corrode the metal would be natural non-sulfuric acid. He could produce it and if he submitted it then it would get him very good award points.
"You carefully analyze everything." Kim looked at Dudian..
Dudian smiled and replied.: "Everything was made by the God of Light. That's why I can get inspiration from everything that he gives us."
"The teacher often warns us that we have to learn to observe the world. The truth is hidden in every corner of the world. Everything is in front of us but we can't see through the illusions." Kim sighed as she said.
Dudian nodded slightly and felt the same way.
Time flied by and the night came.
The banquet ended in splendor. The guests began to leave one by one.
Dudian and Kerry stood by the door and send the guests away. After the influential nobles left Dudian returned back to the hall. The rest were bid farwell by Kerry as most of the were from small factions.
"We should get back." Kim stood up when she saw Dudian come back.
Dudian asked.: "Aren't you going to stay more?"
"No, the teachers are tired." Kim laughed: "The next time we can have a better chat. I believe that soon you will become a senior architect. Afterwards I can ask the teacher to let you work with us. In that case we can talk and discuess many things every day."
Dudian laughed: "Of course."
Both masters finished the tea in their cups and stood up. They saw the expressions of their students. The old man on the left said.: "We will leave now. In the future if you have a need for help don't shy but ask any of my two students."
Dudian nodded in appreciation.
"I heard that you had gone and asked old Eivissa for the task. His studies are way too dangerous. One day he will kill himself. You should concentrate on wood element." The other old man earnestly said.
Dudian nodded and said.: "I know."
Both of the masters looked at him but no longer said anything. They left as their students followed after them.
The other aristocrats greeted them but both of the masters didn't even take a glance. They directly left the hall. The aristocrats who tried to approach them were embarrassed.
"Finally finished." Kerry returned back to the hall.: "It was nice to see that two masters and three senior architects came over to congratulate you. Although you are an intermediate architect but I believe that in their hearts you are not inferior to senior architect."
Dudian nodded. This was the influence of the masters. Just by appearing in the banquet they had improved his 'worth'.
"I was hard on you today." Dudian said to Kerry.: "The next time the meal is on me."
Kerry smiled.: "Alright, I will remember that."
Dudian knew that Kerry was involved in staff management but his character was sleek and people appreciated him a lot because of his generosity.
At the moment, there were no guests left in the hall. However servants were sorting the garbage and cleaning the tables. Dudian found Old Fulin who was sitting on the sofa.: "Patriarch, I'll send you back."
"Alright." Old Fulin smiled and knew that Dudian had something to say him in private.
Dudian bid farewell to Kerry. He helped Old Fulin to leave the hall. There was cold wind blowing outside the manor. Dudian looked at simple coat Old Fulin was wearing. He took off his coat and made Old Fulin wear it.
Sander saw Dudian's move but he stayed silent as he followed Old Fulin and Dudian.
"Master." The butler and coachman was standing in front of the carriage.
"We are going back." Old Fulin ordered them.
Dudian helped him to get on the carriage. Butler and Sander used the second carriage.
It was late night so the Ryan castle was quite. As Dudian and other went into the castle they saw a girl sleeping in living room. She was Old Fulin's granddaughter Lena. She was 14 years old. It seems she was waiting for them but fall asleep in the living room. Servants had covered her with a thin quilt.
"What has happened?" Old Fulin looked at her.
One of the maids whispered.: "Lena was waiting for you, sire. She fall asleep in here and we didn't want to disturb her. I will wake her up."
Old Fulin looked at the sleeping girl's face. He sighed and said.: "Take her back to her room." Then he relied on crutches to walk upstairs to second floor.
Dudian helped old Fulin while he took a glance at the girl lying on sofa. Barton and the others had given him full information about Old Fulin's family. The girl was the daughter of Old Fulin's fourth daughter. The fourth daughter had married a wealthy businessman but died while giving birth to her daughter. Old Fulin took back his granddaughter and took care of her because of her mother's sake.
The maid woke up Lena. The girl opened her sleepy eyes and looked around. She saw Old Fulin and dudian walk upstairs. She bit her lips and wanted to tell something but was stopped by the maid. The maid whispered.: "The master is tired and asked us to take you back to your room."
Lena looked at her. She was slightly bitter but didn't say anything. She got up and left to her room.
