Chapter 342

The jokaus River, one of the many tributaries of St. dreyface, is a humble one.

This river is not very famous in St. dreyface, but it has some fame in St. dreyface, but it is bad reputation, not good reputation. Because the river depth ranks the first among all rivers, and the lack of river management leads to the overgrowth of water and grass at the bottom of the river, many people drown in the yokaus river every year. As time goes by, very few people dare to get close to the yokaus river.

Constance took the four men to a remote part of the jokaus River and took out the dead card sealed in his hand. Constance really didn't expect that quince's assignment for four people would bring her such a big surprise.

In more than ten days, the four apprentices even produced an underwater submarine, although it was a small submarine with two or three seats.

This is the particularity of the design drawings mentioned before. In this era when there is no concept of submarine, who can think that the design in the drawings will be used underwater, and it is the reason of the first draft. Some vague conceptual design will even mislead those who steal.

However, Constance is very clear about the potential of submarines. After all, she has quince's memory. She knows some common sense things of quince's last life.

After reading the drawings of the four men's design, Constance was generally aware that the submarine created by the four men was still very immature. Although the principle was similar to that of quince's submarine, its implementation was completely different.

The four made full use of the principle of mysterious steam to inject steam into many airbags so as to increase and reduce the volume of submarines to realize deep diving up and down, which is very similar to the principle of motorboats.

As for why not pour water into the submarine to achieve up and down deep diving, Constance also knows that mysterious steam has penetrated into the hearts of people in this world. No matter what you do, the first thing you think of is to use steam, not water. This limitation of thinking is hard to break. This limits the development of the world to a certain extent, but it also makes the steam machinery develop vigorously. Who can tell the gains and losses here.

Crush the seal dead card, the submarine floats quietly on the water surface, surrounded by a circle of inflated air bags has been filled with mysterious steam, because of the characteristics of mysterious steam, even a few small air bags can support the buoyancy of the submarine's weight.

Pamela nervously went to the submarine and pulled a hidden pull rod on it. The sound of steam pressure stretching came slowly. A small gate with only one person slowly opened outward, revealing three simple and rigid seats inside. There were more than ten pull rods, buttons and dashboard around the seats, which were very metallic. Of course, because of the funds, the space in the submarine is very compact, and the design of four people makes use of almost all the spare space.

Pamela turned to look at the three people behind her and said, "who's going to try?"

"Pamela, you know the structure of submarines best. You are the master. Ursula, you are the secret of water. It's up to you to make any mistakes in the experiment. Sander, you stay on the shore." Thomas asked carefully.

The other three all nodded, with no objection to Thomas's arrangement.

After the three people sat down one after another, Pamela pulled the pull rod on his right hand, and the gate closed slowly.

On the submarine, there are some glass windows inlaid with strong alchemy glass to observe the underwater scene. This kind of strong alchemy glass is also a very expensive place. As for the periscope, it's not that there is no money, but that there is no place to play, so there is no design.

Under Pamela's operation, four small propellers distributed around the submarine adjusted their direction and started. Under the power of the propeller, the whole submarine drove slowly towards the middle of the river.

A minute later, the submarine slowly stopped in the middle of the water. In the submarine, Pamela put her hands on the direction control lever, and her voice trembled slightly: "Thomas, start to extract 10% of the air bag steam, and equip for diving."

"I understand! 10% steam extraction. " Thomas twisted the left-hand rotary knob to ten scales, slowly pulled the right-hand pull rod, gadagada, the sound of gear bite gently sounded, and then the submarine began to slowly sink.

Soon, the three felt that their submarine was sinking slowly. Through the window, they could clearly see that the water level outside was rising.

Soon, the water level was beyond the window, and the visibility was not very clear. After the submarine reached five yards, it stopped.

After that, Pamela repeated a series of operations such as inflation, pumping and driving. After staying underwater for more than half an hour, the submarine slowly floated up.

Stooping out of the submarine cabin, the three men could not hide their excitement. The original intention of making the submarine was initially realized, but after half an hour's operation, they still realized that there were many shortcomings in the submarine.

Constance clapped her hands and congratulated, "it's very good. Your project has been preliminarily completed."

Speaking of this, the four people can't help looking at Constance one after another. Thomas asked, "teacher, is our project qualified?"

Constance shrugged. "I am not qualified, I am not the one who has the final say. Rules are rules. Since I have raised the requirement to go to 4 level, then no matter how successful your project is, you can not get to the 4 level without any promotion."Constance can't help it. The condition is quinstein's. If she doesn't follow his rules, she won't be able to follow up the four apprentices. At that time, she doesn't want to see chicken flying and egg beating.

The four were disappointed, but since quince had made the offer before, quince could not beat himself in the mouth.

"Well, let me ask you, what have you got from the experiment of more than half an hour?" Asked Constance.

Thomas was the first to reply: "our submarines still have a lot of potential and shortcomings. One of the most obvious shortcomings is that we have not taken into account the underwater environment. The yokaus river is already a very clear river, but after we dive to ten yards, the visibility in the water is only three yards, which is not enough for underwater navigation. We need to improve on that. "

Ursula and Pamela nodded repeatedly, which was so obvious that they noticed as soon as they dived.

"There is also the problem of air," Ursula said. "After diving for 10 minutes, the air in the submarine is very thin. Finally, I solved the problem of air by using the secret technique of underwater breathing. However, if we want to popularize submarines, it is impossible for every submarine to be equipped with an extraordinary person who specializes in the secret technique of water elements."

Pamela went on: "and the situation on the surface, after diving, we know nothing about the situation on the surface, which needs to be improved. The other is the unreasonable distribution of internal machinery. I feel that there is no problem with the internal machinery when it is put on the water, but when it is underwater, because of a series of problems such as water pressure, the transmission deformation of the internal machinery may be caused. In a short time, there may be nothing to see, but if it is used for a long time, there will be problems. "

"Then there is the problem of rust prevention. Our funds are not enough to support us to develop a rust proof coating for submarines." Thomas added.

Then everyone talked about some minor problems of submarines. Generally speaking, there are major problems and many minor problems.

Constance nodded repeatedly. Although there are many problems with submarines, the experiment just now has proved the feasibility of four man submarines. As long as the direction is correct, all problems will be solved. The only difference lies in the investment of funds and time.

As a matter of fact, it's not likely that the four of them will make a fortune with this patent for such a thing of military value. At most, after the four apprentices released the project, the government departments came to the door and made a symbolic purchase. Even other countries don't even have to pay for it, so they directly develop it secretly.

After all, submarines are mysterious, but as long as their functions are exposed, some alchemists can develop more advanced, larger and more terrifying underwater war weapons than the four apprentices.

After sealing the submarine again, Constance left, and, as she said, by doing so, they were able to hand over the shabby thing. After all, no matter how much this thing is modified, they will not get much benefit in the end. However, Constance did not interfere much in whether the four eventually improved and then handed in the project or handed it in now. Although this matter is related to quince's teacher upgrading, it is closely related to the four apprentices' own interests. If we do it better, we can increase the probability of upgrading.

Three days later, quince, who had just come out of the basement, met the four apprentices.

Looking at the smile from the heart of the four, quince knew that the test of the four little guys must have passed.

Quince picked up the grade 4 Teacher Certificate on the tea table and looked at it. He immediately put it down. He had learned the basic information from Constance, but he was very curious. How did the four choose in the end?

"We listened to some of the teacher's opinions. After we went back, we corrected the shortcomings we found on the drawings and submitted them to the Royal Academy." Ursula.

Thomas continued: "I didn't expect that in less than one day, the people from the Royal Academy came to the door. In addition to the teacher's level 4 teacher certificate, they also proposed the intention to purchase the remaining 90% of the patents."

"We have always agreed to sell the patent to the Royal Academy because of the teacher's previous opinions." Pamela took out a check with 100000 OMOs and put it in front of quince.

"100000 Omo gold coins, I want to pay so much for the Research Institute, I want you to keep it secret." Quince picked up the check, thought about it, and handed it to Butler browning, who was standing behind him.

"I'll pay you the 100000 Omo gold coins in advance for your purchase of level 2 esoteric and mysterious knowledge. If there is any balance, I'll ask Browning to return it to you."

The four were overjoyed to hear quince's words.

Ursula: teacher, you mean we passed the test

"I always mean what I say. Now that you've got the level 4 teacher certificate, you've passed the test." Quince waved his hand indifferently: "find browning before you leave, he will give you the catalog, select the mysterious knowledge you need, and then go directly to browning."

The four apprentices left happily with the list of contents they got from browning. When they returned to the research room, they studied the list first according to the old rule.

This time, the list of contents that the four people got was distinguished. In addition to the secret biography of level 2 and basic level 2 mystical knowledge of the four people, Ursula's list contained a series of mystical knowledge that must be possessed by the transcendent of water elements, such as water elements, water geography, water and breeding, water change, water healing, etc. in the back row, there were a lot of words that must be read, and you can see Huera's scalp is numb. Ursula made a rough estimate in his mind, and all this knowledge was replaced with 30000 Omo gold coins.Thomas' list is not in vain. Psychology, psychoanalysis, psychic powers, psychic powers, self hypnosis, psychic premonition, psychic divination

One set down, forty thousand Omo gold coins out.

On Sander's list, dreams and the future, dreams and the past, dream analysis, dream world introduction, how to dream Fifty thousand Omo gold coins are indispensable.

The most terrible thing is Pamela. What the inventor learned is alchemy, but what supports Alchemy to play its greatest role is rich mystical knowledge and alchemy knowledge.

Mystical botany, mineralogy, mechanics, steam science, elemental analysis, strange physics, cryptic Pharmacy And so on a series of knowledge, alchemists advance knowledge accumulation, absolutely can let the rich feel that they are a fake rich. This series of 7788 down, at least 100000 Omo gold coins start, if you include a series of notes for elective knowledge, absolutely up to 500000.

Four people get together a total, must, that give out 100000 o Mo gold coins don't want to take back the balance.

Thomas gave a wry smile and said, "that 100000 Omo gold is really not enough. Let's discuss it first. Everyone should buy the knowledge they need most. For others, we need to find more ways to make money."

Pamela said bitterly, "what should I do? How long will it last? "

Ursula said with a smile: "you are content. Do you know what life those alchemy apprentices in the research institute are

Pamela snorted: "needless to say, the three-year apprentice is just doing chores. If he wants to learn something real, he will be exploited by his tutor, and there will be no complaints." How could Pamela not have inquired about those alchemy apprentices in the research institute? When she learned about this, Pamela's heart was half cooled. She thought she would have three years of apprenticeship, but what she didn't expect was that the road turned around.

Although alchemists all look up to bright and spend money like dirt, in the early stage of alchemy, they are definitely the most difficult profession. There is no one of them. According to statistics, as many as 80% of the people in the apprenticeship stage of alchemy do not insist on changing to other professions.

"It's good to know. If you let the alchemists know that you can learn so much about alchemy just by paying a little money, everyone will be jealous and want to kill you instead." Ursula Tucao Pamela, the heart is not make complaints about surging up.

Because of her family background, Ursula knew very well that the catalogue she had was definitely one of the over specifications. As far as she knows, except for the necessary basic mysterious knowledge and level 2 esoteric biography content, it is impossible for the general tutors to put them on this list. The apprentices want to buy these rare mysterious knowledge related to esoteric biography, and they don't get along with each other for several years. They want to get the trust of the tutors. They really want to get this kind of standard list.

Quince, however, took it out so easily. What's more terrifying is that the length of the list of four people has gone far beyond the scope of an ordinary Superman, even if it's only the content of level 2 mystics.

They all vaguely felt that their teacher, who was recognized by fate, was far from as simple as he seemed.
