After dinner, Roland returned to his office and continued to copy the basic math in his head onto paper.

He doesn't have the ability to memorize, and not only that, but his memory deteriorates over time. Mathematics and physics, which are still frequently used subjects, are estimated to have degraded to the entry level due to their specializations, while other knowledge such as history, geography, biology, and chemistry has been degraded to the entry level. Therefore, whether you use it or not, you can retain more knowledge by writing down what you haven't forgotten earlier.

Every time he filled a piece of paper, he had the scroll next to him glance at it. As long as the content is seen by her, it is equivalent to being preserved forever. It's a pity that the ability to read books is only related to memory, and it doesn't make her self-taught about middle and high school math. Therefore, when he has time, Roland has to explain it to her.

Of course, for him, who is a good teacher, preaching and teaching is a very interesting thing. Especially when he saw the scroll and was shocked, or the expression of sudden realization after meditating, he also felt a sense of accomplishment in his heart. However, Roland knows that this also has something to do with the target audience. Although the scroll was nearly forty years old, the magic slowed down the aging of her face. The skin on the cheeks is still tight and ruddy, and the long black hair is simply tied behind the head, giving it a mature and capable look. The subtle crow's feet at the corners of the eyes do not destroy the overall beauty, but rather bring out the steady temperament. In the movie, it is definitely the role of an elegant all-round teacher. Now, he can make the "teacher" stunned, and this contrast is quite useful.

While writing silently, Roland is also thinking, what is the magic of this world?

Everywhere it goes, from the depths of the Mines on the North Slope to the desperate mountains, from the Wild Lands to the west to Seabreeze County to the east, witches can use it to unleash all sorts of incredible powers. If magic is thought of as electricity, witches are electrical appliances with different functions. But obviously it is much more incredible than electricity, more like an energy close to the "source".

For example, Hakara of the Mutual Aid Society, Wendy says that she can summon four magical serpents, named Death, Pain, Petrification, and Nothingness, with different venom effects. Another example is the nightingale, where the unfolding fog almost distorts space. The manifestations of these abilities are ever-changing, and Roland really can't think of a more appropriate word other than the word origin.

If we want to give a definition of the source, it is probably a universal and universal rule. In the second half of his life, Einstein was determined to integrate the four fundamental forces of the universe into a theoretical framework, which is the so-called grand unification theory, and in a sense, what he did was to find the source. So will there be a one-size-fits-all rule that can be applied in any universe?

This point made Roland can't help but open his mind, could it be that he traveled through the previous world, and there is also such power, but there is no witch as a release window, so that it has been ignored by people?

No matter what, Roland could only think about it, after all, with the current level of technology, he couldn't analyze this kind of power at all.

Therefore, it is our main task to promote industrial development and promote the progress of civilization.

Perhaps one day, people will be able to harness this power without the help of witches - a versatile super-energy source that can be transformed into multiple effects at the same time, and the mere thought of is exciting.

"Your Highness?" Shujuan couldn't help but ask out loud when he saw the prince's intoxicated look.

"Ahem," Roland said, recovering from his delusions, coughing twice, glancing at the candle that was about to burn to the end, "and that's all for today." ”

"Yes," she bowed her head and saluted, unconsciously slowing down as she prepared to leave.

Roland didn't hear the door close for a long time, and looked up a little strangely to find that the other party was still at the door. "What's the matter?"

"Your Highness......" the scroll hesitated for a moment, "I want to ask you a question. ”

"Just ask. Roland nodded, put down the quill in his hand, raised his glass and took a sip. These witches are good at everything, except for a little bit, too unconfident. Like a rabbit poking its head out of the mouth of a cave, it retracts into its hole in fright at the slightest disturbance, and never dares to come out again. I guess her question is why you want to contain us, and aren't you afraid of the threat of the church? Nightingale and Wendy had asked him many times. However, since the other party has put on such a posture, he naturally has to answer seriously, so that they can deeply feel that they should treat their comrades as warm as a spring breeze.

"You...... Is it possible to marry a witch?"

"Poof," Roland almost didn't squirt the water out of his mouth, "uh, why do you ask that?"

"I ......" the scroll opened its mouth, but could not answer.

Marry a witch? Roland was the first to think of Anna, and from the moment he met her in the cage, his lake-blue eyes left a deep impression on him. Witches are women who have awakened to ordinary humans, and they are superior to ordinary people, from their appearance to their bodies. If it is placed in modern society, it must be the focus of attention. So, what do you have to hesitate?

He looked at the scroll and replied with a smile, "Why not?"

Wendy rubbed her sore shoulders and went back to her room.

Her heavy chest always caused her a lot of troubles, especially when standing on the top of the wooden shed in the town to attract the wind, and the raised hands had to be slightly backwards to maintain the balance of the body.

Based on the first sea trials, a number of improvements have been made to the Town. For example, a simple shed has been erected where she stands, which can not only protect her from the wind and rain, but also from the sun. A ring of bark was hung around the hull to reduce collisions when docking. Two short cement piles were installed on both sides of the ship's side to facilitate the hemp rope to secure the boat.

And her ability to control the wind has also improved greatly after nearly a month of training. Now that the boat is moving more steadily and can be faster or slower under the influence of the wind, she has also learned to use the existing wind to adjust the mana consumption so that she can last longer.

Nightingale had finished bathing before Wendy, and was already sitting at the head of the bed in her pajamas.

But what made her strange was that there was an irrepressible smile on the other party's face.

"Did anything good happen?" Wendy couldn't help but ask, and the latter shook his head and didn't say anything, just smiled a little deeper.

Wendy pouted, her mood hadn't been very high since the last night talk with her, and it had only improved since the recent popularity of Gwent cards in the castle. Where did the expressionless and taciturn Shadow Killer who first met in Silverlight City go?

With that, Wendy took off her clothes and stepped into the bucket filled with hot water, presumably she had won a good card. (To be continued.) )
