At three o'clock in the morning, Professor Erbach slept until he woke up naturally.

Last night he and his old friends drank too much at Aixi's restaurant, and in the end he couldn't remember a lot of things, and his head still hurt a little.

He changes his clothes, washes up, and goes to the restaurant for a bite to eat.

The cook had already prepared hot white porridge for him, as well as a small plate of pickled radish.

There was also a memo on the table, which he had asked his secretary to prepare, so that he would not be able to remember what he said when he was drunk.

The old headmaster drank porridge and looked at the memo that he had sold Charles last night and other irrelevant trivialities.

In fact, there was an old guy who had a large group of difficult monsters in his territory, and this group of monsters inhabited the depths of the cave and was difficult to deal with, so he asked Professor Erbach for help.

Then the principal agreed, and decided to send Charles, who presided over the development of today's row, to solve the matter.

So Professor Elbach told the secretary to go to the door of Charles's dormitory and nail a note, telling him to come to him when he returned.

At this time, Charles was catching up on sleep in the dormitory, and the meeting in the epidemic area last night was late and ended in the middle of the night.

Knowing that lime water could effectively kill pathogenic bacteria, Queen Rose brought in truckloads of quicklime by water, and at the end of August, a total of several thousand tons of quicklime were put into the water network in stages, and the number of pathogenic bacteria in the river was greatly reduced.

So we made persistent efforts to disinfect the river with quicklime again before the autumn wheat sowing in the next few days, so as to escort the next autumn planting.

At this time, the amount of water in the river is small, and the setting of the release point and the calculation of the amount of the release are more reasonable than the first time, so it will definitely have a good effect.

It's just that the fish and aquatic plants in the river will suffer in the next period of time, but at this time, the interests are at stake, and the local lords don't want their territory to become a plague land, and those who dare to be forced are tied up and thrown into the river.

Charles had no objection to this, after all, he couldn't come up with a way to be better, more reassuring, and less expensive to use on a large scale.

The main task of the Knights Hospitaller was to disperse the quicklime to the drop-off points and then fall into the river on the same day.

I don't know how long later, a man in a maid's costume woke up Charles.

The college allows student servants to come to the dormitory to help with household chores, and it is not surprising that there are maids in the dormitory building at this time.

"Why are you here?" Charles stretched, but he didn't expect it to be Artoria, "What's the situation with you?"

Artoria said with a dark face: "Mordred got a perfect score in a subject in the monthly exam last month, and I said that she agreed to a condition if she got a perfect score once. ”

(??????)

Charles's eyes lit up suddenly, and he instantly had a plan to take the exam for Xiao Mo at the end of the month.

He asked, "How about you promise me a condition when I get a perfect score?"

If Artoria dared to agree, he would dare to get a perfect score.

As a result, Artoria patted him on the head, "Young man, don't think too much. ”

"Your headmaster wants to find you. ”

Charles took the note nailed to the door, glanced at it, threw it aside, and said, "The headmaster or something is a minor problem, the main question now is what is the matter with you coming to me in this dress?"

Artoria gave him a blank look, "What do you think I can do?"

Charles was taken aback, "Could it be that Mordred got perfect marks in two subjects?!"

Seeing Artoria nodding, Charles was very relieved that he didn't hurt her in vain.

Then he took out a meow ear headband from the storage ring and handed it over, "Can you put it on, let me do whatever I want." ”

Artoria took the meow ear band, took a deep breath, and pressed it on Charles's head.

"I'm looking for you today. She said earnestly, "I want you to do me a favor." ”

Then she took out the best magic crystal that she had snatched from Charles, "Please help me sell it at the next auction." ”

Charles almost jumped, "Mordred is getting married, who is the other party, what kind of work do you do, do you have a house, do you have a car?"

Then Artoria calmed down the guy with a knife in one hand.

"I'm going to use the money myself. She said.

Charles looked at her incredulously, "I heard Mordred say you went on a blind date yesterday...... Ahh

Artoria suppressed Ru and said angrily, "Mordred said she wanted me to mentor her friend, but she didn't expect her to sell me. ”

Charles rubbed the Tianling Gai, which was hit with a knife in another hand, and sighed: "Pity the heart of the daughter of the world." ”

"Back to the point. Artoria said, "I'm going to buy some new weapons, I'm short of money." ”

Charles frowned, Artoria was not short of money, her savings in the Rurik Kingdom for more than three hundred years were a huge amount of money, and she was the invisible rich woman of Abyss City.

A few years ago, she took a large amount of money to buy Intel Corporation's bonds, which provided start-up capital for the company's development, and this money was paid off two years ago.

For the price of this superb magic crystal, you can buy several companies of rough tanks...... It's the kind of tractor chassis welded with steel plates and then equipped with small cannons, the military of the Rurik Kingdom is very disgusted with this expensive, useless, and often malfunctioning thing, and wants to sell it to the elves and is afraid that the friendship between the two sides for thousands of years will be ruined, and now it is all thrown into the military academy.

"What kind of weapon do you want?" asked Charles, puzzled.

Artoria handed him a pamphlet, and Charles's eyes widened at the cover.

"Good fellows!" exclaimed Charles, "these two sisters are really ...... Obey them!"

The booklet was a brochure for a weapon system of the Macroros Group, and on the cover it was a Gundam-like robot that looked like it could fly.

Charles hasn't paid much attention to the Marc Ross Group in the past two years, because the company has entered a stage of benign development, and it may be counterproductive to direct it blindly.

Now the Wright sisters have created an extremely stylish magical power armor system, and are now looking for the wronged boss to be the guinea pig.

However, according to the habitual practice of the Macros Group, the conceptual goods that can be sold must be qualified, and there are some minor faults, and the user will pay for them to upgrade a few times afterwards.

"I didn't expect it to be ready for the market. Charles sighed, saying that this magic power armor system was still the premise of him, but he didn't expect to develop a sample now.

"You don't need so much money to buy a set, do you?" he asked, "If you can't keep it on hand, just talk to me, and I'll help you keep it in your account, and pay 0.05% a day in monthly installments." ”

Artoria gave him a few more drawings, "I don't want the weapon system, I'm going to ask Donna and them for help with weapons." ”

"Good!" Charles was frightened, "Electromagnetic cannon...... There are so many more, no wonder it costs money. ”

In addition to the electromagnetic cannon on the drawing with power armor, there are also individual guns.

Ru's black chicken leg cane can be said to be a verified model of the electromagnetic gun, and it is determined that the miniaturization of the electromagnetic gun is feasible, and now they are confident that they can make a single electromagnetic gun.

Although the manual fee is just a little meaningful, the material fee can't be paid by the machine spirit girls, and Artoria still has to pay for it.

The last drawing made Charles jump even more.

"Oath Victory...... Railgun?" he looked at Artoria in disbelief, "Big sister, your personality is about to change!"
