At the end of the morning, McGonagall took Hannah upstairs to begin the formal drawing lesson.

As a serious (pseudo-)designer with a major in mechanical design, McGonagall still has an extremely solid foundation in design, and with a good memory, she still remembers how the teacher taught them the basics of drawing drawings.

"That's a lot of books." Hannah entered the study, and was first attracted by the fact that the three walls were almost filled with books of all kinds, and at a cursory glance, there were at least five thousand books of all kinds, which she had never seen in her life.

"In addition to this shelf, you can take back any books you want to read on other shelves." McGonagall smiled as she pointed to the bookshelf in the direction of the door.

It's good to read more.

Hannah glanced at the bookshelf that McGonagall was pointing to, and there were mostly books with black and red covers, which seemed to exude some kind of dark aura, and nodded without much thought.

"Come on, today I will teach you how to draw design drawings in a standardized way, so that your design can be presented on the drawings in a gradually clear way, so that more professional craftsmen can make products that meet your requirements." McGonagall walked towards the desk by the window.

"Didn't you do it yourself?" Hannah followed, a little confused, feeling that it would be difficult for others to understand what she was going to do.

"Our goal is to make standardized brewing equipment, except for the deployment by you, other processes can be completed by machinery and workers, so that it can be regarded as a mechanized large-scale brewery." McGonagall pulled out a piece of white paper from a nearby shelf and placed it on the table, looked at Hannah and said, "So, we have to ensure the accuracy of the machine, which requires a professional blacksmith to do." ”

"Oh." Hannah nodded thoughtfully, then looked at McGonagall a little worriedly, "Wouldn't that be hard?" I used to draw casually, and I just needed to be able to understand wherever I wanted to draw. ”

"It's okay, I'm a professional." McGonagall motioned for Hannah to sit down next to her, and she sat down at the desk, and said, "Let's first take a look at the tools commonly used for drawing, this is a pencil and an eraser, and this is a ruler......"

McGonagall began by understanding the tools and began to teach Hannah the steps and methods of standardized drawing.

Floor plans, three-view views, three-dimensional drawings, unfamiliar words jumped into Hannah's mind, looking at the graphics that jumped out of McGonagall's pen, and the neat and comfortable way of labeling, all made her feel like she had opened the door to a new world.

The boss is indeed a master mechanic!

However, McGonagall spoke too quickly, and the amount of information was too much, although she had tried hard to memorize, and even held a small notebook to record some important points, but it was obviously unrealistic to fully grasp these things in a short period of time, and she could only wait for herself to digest and practice slowly.

About an hour later, McGonagall took a sip of tea from the teacup she was holding, moistened her parched throat, looked at Hannah, who was slightly glazed over, and asked, "Will it be?" ”

"Huh?" Hannah looked at McGonagall a little blankly, is this asking human words? Although she understood what McGonagall said, it was a different matter from the meeting.

"It doesn't matter, as a professional teacher, you won't order anywhere." McGonagall smiled and held out her middle finger.

After a while, Hannah, whose eyes were glazed, regained her clarity, looked at McGonagall sitting across from her in disbelief, and said in surprise: "Boss! I'm in total! ”

"No, you just know it in your head, drawing is a thing that needs to be practiced, today you just stay in the study and draw, and draw all these drawings I just laid out for you." McGonagall got up and gave up her seat to Hannah, and went straight out the door and downstairs.

"That's amazing, isn't it? The boss tapped my forehead, and it was amazing that I had learned everything he had learned in the morning. Hannah's expression was still uncalm, and in a short period of time, she had learned everything McGonagall had taught her, including how to use the tools and how to draw professional drawings and size them properly.

"Is this the boss's superpower?" Hannah thought for a moment, feeling like she had discovered her boss's extraordinary abilities beyond cooking.

"Calm down, calm down! Now it's time to start drawing. Hannah took a deep breath, trying to calm herself, then picked up a pen and paper and began to complete the task assigned by McGonagall.

Although it was her first time to use professional tools to paint, she was already familiar with all the methods and steps in her mind, and the technique was a little jerky, but it did not affect the brush to draw lines and shapes on the paper.

"Not bad, but not professional enough." Ten minutes later, Hannah looked at the first drawing she had drawn, nodded with satisfaction, and then threw it aside dissatisfied, took the second piece of paper, and drew it again seriously.

Shortly after McGonagall descended the stairs, Dix came to him with Michael's orders and went to the Lord's Mansion.

McGonagall could probably guess why Michael was looking for him, so she changed her clothes, carried the stone box containing the strange stone statue on her body, and got into Dix's carriage to the City Lord's Mansion.

"Boss Mai, Miss Reina's matter, I want to apologize to you first, or in a few days, this matter will be completely resolved, there are some moths inside the City Lord's Mansion, I need to clean it up carefully." As soon as McGonagall arrived in the secret room, Michael got up and said with a sincere face.

"It's not me who has been hurt, and it's useless for you to apologize to me." McGonagall shrugged her shoulders, he was indeed a little upset about the City Lord's Mansion.

"I'll apologize to Miss Rena myself later." Michael nodded.

"These things will be put aside for now, let's talk about the evil gods and the devil first." Roland closed the door of the secret room, activated the multi-level anti-peeping formation, and said in a deep voice.

"Boss Mai went to the Fak tribe this time, but did he really see the devil with his own eyes?" Michael asked, looking at McGonagall.

"The detailed report, as well as my previous conversation, I believe that the city lord has already seen it, maybe it is a little ridiculous, but we have to admit that there really is a devil in this world. Or a powerful being that existed in ancient times, but has survived to the present, I call them: the Old Dominators. McGonagall said in a deep voice.

"Old Dominators." Michael read word by word, his brows furrowed tightly, and he was a little puzzled: "If there really is an old ruler, then why has there never been such a record in the history of the Nolan Continent?" ”

McGonagall thought for a moment and said, "I've been thinking about this for a while, there are two possibilities: 1. The Nolan Continent was completely destroyed, and the current world was slowly redeveloped later, so there is no relevant record; 2. The history of the Norlan Continent has been artificially modified, erasing all information related to the old rulers. ”
