Release that Witch

The witch and the First Army have been out for four days. According to the plan, they should arrive in the suburbs of Yinguang City tomorrow afternoon.

After the flight messenger equipped with honey, Roland received the letters sent by the team every day. There were iron axe, Anna, and nightingale. Although it was not as fast as a mobile phone, it was basically a radio report. Similar. If the flight messenger on this line is several times more, there will always be birds going back and forth between the two places, and maybe even simulate the effect of SMS chat.

On the days when the night was gone, the chief knight took over the responsibility of defending the castle. But what makes Roland puzzled is that Carter is always a happy look these days, and seems to have encountered something very happy. Is it worth the time to return to my job and be responsible for personally guarding myself?

He shook his head and turned his attention to the report of the Minister of Construction, Carl Vabert.

With the help of the Sleeping Island Witch, this construction project in Bianbu Town has been progressing for a long time.

First of all, the steel bridge on the Chishui River was successfully completed. Compared with the traditional stone bridge and wooden bridge, the steel bridge can be pre-made, and then the overall lifting, plus the two floating islands raised by the lotus in the river channel, further simplified Its difficulty in setting up the bridge shortened the construction period of the main bridge to an astonishing month.

Despite the eyes of the future, it is short and narrow, the structure is too simple, and the load is extremely low. It is a material waste of the bean curd project, but in this era it has been regarded as a magnificent super bridge with a total length of more than 100 meters. The bridge deck is straight, two carriages can be used side by side, and the lower part can also meet the inland river sailing. No matter what is not a heavy stone bridge can be done.

Secondly, the new wall of the lotus has also been closed. This purely muddy wall has more than doubled the area of ​​the town. If it is built in the future, the original town will become a veritable "inner city." However, Roland is more inclined to say that one ring and two rings, perhaps one day, this place can also be expanded into a giant city with seven rings, officially crowned the name of the emperor.

Finally, the construction of the Kingdom Avenue, some of the foothills that have spread along the desolate mountains are reduced to the flat by the lotus, so that the road can pass straight, greatly reducing the total construction period.

"His Highness, what is your next step in the construction of the lotus arrangement?" Carl asked after reporting the progress.

It can be seen that he is envious of the ability to transform the terrain, but he has not asked him to include her in the Ministry of Construction and has appointed the Deputy Minister.

“Hey...” Roland is also thinking about this issue, and then he has three major renovation projects to be implemented.

The first is the estuary project: looking for a low gap in the southern end of the mountain, and then sinking into a road that can enter and exit the shoal. This must be done by the ability of the lotus. Once the renovation is completed, Westland has a harbor facing the sea.

The second is the expansion of the residential: although the city hall has invested a lot of human and financial resources to build a residential community, but in the winter, there may still be nearly 3,000 people unable to live in the warm brick house. The wooden sheds and simple houses that are now set up are simply unable to meet the needs of the cold, so he needs a group of cave houses with thick walls and fire to solve this problem.

The last point is to set up a dock: to produce a shallow-water heavy gunship, he must first lay a spacious dock, and still can not affect the passage of the Chishui River. Roland intends to lower the height of a river bank in the west of the town, form a dry dock, and install a lifting gate on the side near the Chishui River to control water and water release. The scale of the earthwork of the project is huge, and it must be done by the ability of the lotus.

After considering it for a while, he finally decided to put the expansion of the house to the first place. Since the Dongfu fugitives were brought to the border town, they would be responsible for their food, clothing and housing. If you die of starvation, it will not only be a loss of the West, but also reduce the sense of belonging of the people to the place.

"So where is this temporary home built?" Carl asked.

“It’s just in the current serf shantytown,” Roland glanced at the map. “Away from the city wall defense, there are also desperate mountains to shelter the wind.”

After the construction minister retire, he just wanted to take a nap on the chair, and Camo Spoel came to the door again.

"His Royal Highness, the large-scale acidification method you requested, I have successfully developed it."

This sentence suddenly dispelled Roland's tiredness, and he was pleasantly surprised to stand up from the table: "Really? Take me to see."

A group of people came to the laboratory at the Chishui River. I saw a few gray-white cans and a kiln next to the No. 5 laboratory. Each can has about two people high, and the top is connected by pipes. The smooth and smooth shape is obviously It was cut by Anna.

"To pay tribute to you, Your Highness," a young man who looked very young and bowed to Roland.

"Are you Chammes?" Although it has long been known that Kaimo has dug a group of alchemy apprentices from Chishui City and has also drawn an outstanding alchemist, he is still seeing the other side for the first time today.

"You remember my name," Chames was surprised.

"Mr. Camo has mentioned you many times," Roland patted his shoulder to show encouragement. "Do it well." Then he looked at the chief alchemist. "How does this thing make acid?"

Kemo smiled with a beard and said, "It can be developed successfully. It is derived from the reaction formula of "Elementary Chemistry." Look at the kiln, the purified sulfur will be burned in the kiln, and the generated gas passes. It is further heated and sent to the lead can."

“Is these devices made of lead?”

"Yes, only lead can resist the corrosion of acid." Kaimo nodded. "The lead pipe at the top of the can is continuously sprinkled with nitric acid. Under the hot sulfur dioxide gas, the nitric acid is decomposed into nitrogen oxides by heat, and finally with water. Sulfur dioxide produces a sulfuric acid solution, which flows out from the bottom of the hole. This reaction is ingenious in that nitrogen oxides only play the role of transmitting oxygen, and there is no consumption of it. Therefore, the amount of nitric acid is not large, and once the reaction starts, the energy source is continuously carried out. Go on!"

"How is it produced?" Roland asked excitedly as he shot the lead can. Large-scale acid production is a prerequisite for mass production of smokeless gunpowder. If this problem can be solved, a new generation of ammunition with guns and artillery will have hope.

“This is the fourth device I tried. The output of one day is probably worth the week of the laboratory dry distillation method.” The chief alchemist said proudly, “Because of the experimental factors, its volume It is not big. If a larger capacity lead can be built, the output can be further improved."

"This is really good news," Roland said with a smile. "When Miss Anna returns, you will immediately start building a larger sulphuric acid plant. If the lead is not enough, you can use iron instead. Miss Soroya's coating can make The iron is free of acid corrosion."

Kemer nodded, but his next sentence made the prince's smile stiff.

"Now the large-scale acid production method has achieved results. The five laboratories are all filled with apprentices. Your Highness, can you give me the "Medium Chemistry" promised?" (To be continued. Your support, It is my biggest motivation.)
