Release that Witch

305. Chapter 305 Chemical Breakthrough

    Witch and First Army set off have been around for four days, and they are scheduled to arrive in the suburbs of Silver Light City tomorrow afternoon.

    Equipped with Honey’s flight messenger, Roland received daily mail from the team, including Iron Axe, Anna, and Nightingale. Although not as fast as a mobile phone, it is basically similar to a radiotelephone. It is. If the flight messenger on this line is several times more, there will be birds going back and forth between the two places, and maybe even simulate the effect of SMS chat.

    On the day when Nightingale was gone, Chief Knight took over the responsibility of defending the castle. But what makes Roland puzzled is that Carter For several days is always a happy look and seems to have a very happy time. 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 Karl van Bate.

    With the help of Sleeping Island witch, this Border Town’s construction project has been progressing for more than a month.

    First of all, the steel bridge on the Scarlet Water 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 floats raised by the lotus in the river. The island further simplifies the difficulty of its erection, making the main bridge construction period shortened to an astonishing month.

    Despite the vision of posterity, it is short and narrow, the structure is too simple, the load is very low, is a waste of material of the Tofu slag project, but in this era has become a magnificent super bridge-the total length of more than 100 meters, and the bridge deck is straight, can be used for two carriages, the lower part can meet the Inland River Sailing, No matter what is not a heavy stone bridge can do.

    Secondly, the new wall of the lotus has also been closed. This purely muddy wall has doubled the size of the small 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 spread along the Impassable Mountain Range were lowered to the ground by the lotus, allowing the road to pass straight, greatly reducing the total construction period.

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

    It can be seen that he is envious of the ability to transform the terrain, only to face the proposal to include her in the Ministry of Construction and to appoint the Deputy Minister.

    Hmmm…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 ridge 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 transformation is completed, the Western Region has a harbor facing the sea.

    The second is the expansion of the residential: although 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 a warm brick house. The wooden shed and the simple accommodation that are now set up are simply not enough for the cold, so he needs a bunch of cave houses with thick walls and fire to solve this problem.

    The last point is to build a dock: to produce a shallow water heavy gunship, he must first lay a spacious dock, and still can not affect the passage of Scarlet Water River. Roland intends to lower the height of a river bank at the west of the small town, form a dry dock, and install a lift gate on the side close to the Scarlet Water River to control the water and water. 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 in the first place. Since the eastern region refugees were brought to the Border Town, they were responsible for their food, clothing and housing. If you die of starvation, it will not only be the loss of the Western Region’s, but also reduce the sense of belonging of the citizen.

    “So where is this temporary home built?”Karl then asked.

    “It’s in the current serf shantytown,” Roland glanced at the map. “Away from the city wall defense, the Impassable Mountains can be shelter.”

    After the Minister of Construction retired, he just wanted to take a nap on the chair and Cam Schuire 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 on the side of Scarlet Water River. I saw a few gray-white jars and a furnace set up next to the No. 5 laboratory. Each jar was about two people high, and the top was connected by pipes. The regular and smooth shape was obvious. It was cut by Anna.

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

    “You are James?”Although it has long been known that Cam has dug a group of alchemy apprentices from Scarlet Water City, he has also drawn an outstanding alchemist, but today he is the first to see each other.

    “You remember my name,” James was surprised.

    “Mr. Cam has mentioned you many times,” Roland patted him on the shoulder to show encouragement. “Do it well.”Then he looked to the chief alchemist, “How does this thing make acid?”

    Cam smiled and smiled. “It can be developed successfully, according to the reaction Derivation on «Elementary Chemistry». Look at the furnace, the purified sulfur will be burned in the kiln, and the generated gas is further heated and sent to the lead can. ”

    “Is these devices made of lead?”

    “Yes, only lead can resist the corrosion of acid.”Cam nodded, “the lead tube at the top of the jar is constantly sprinkled with sulfuric acid, in the hot sulfur dioxide gas, nitric acid heated decomposition into nitrogen oxides, and finally with water, sulfur dioxide to generate sulfuric acid solution, from the bottom of the hole outflow-the subtle reaction in the nitrogen oxides only play the role of oxygen transfer, itself is not consumed, So the amount of nitric acid is small, once the reaction starts, it can continue to go on! ”

    “How is its output?”Roland asked excitedly about the lead can. Large-scale acid production is a prerequisite for mass production of smoke-free gunpowder. If this problem can be solved, a new generation of munitions and cannon ammunition 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 proudly said, “Because of the experimental factors, it is not very large. If a larger capacity lead can be built, the output can be further increased. ”

    “This is really good news,” Roland laughed. “When Miss Anna returns, you will immediately start building a larger sulphuric acid plant. In addition, if the lead is not enough, it can be replaced by iron. The coating of Miss Soraya can protect the iron from the corrosion of the acid. ”

    Cam nodded, but his next sentence made the prince’s smile stiff.

    “Now the large-scale acid-making process has yielded results. The five laboratories are all filled with apprentices. Your Highness, can you give me the “Intermediate Chemistry” promised?”
