Lina looked at the female mage in front of her in a daze and thought to herself: Could this woman be the mentor in charge of teaching the apprentices? Thinking of this, she tugged at her brother's clothes and asked, "Brother, who is this sister?" ”

"Her name is Debra, and she's in charge of teaching all the apprentices here. If you have a problem later, you can ask her. Henry lowered his head and explained to his sister.

Debra hurriedly came back to her senses when she heard the words of the brother and sister, and she bent down to Lina and said, "Welcome to the Mage Tower, there are more than thirty apprentices here besides you. But they're much older, so I'm sure you'll get along well. Although your brother is the owner of this place, you better not expect to be taken care of too much. ”

"I don't need any special care, and I will do all my studies on my own." After saying that, Lina raised her head proudly.

"I like your pride and ambition, and I hope you can stick to it in the future." After saying that, Debra raised her head and said to Henry, "Master, give her to me." I believe that your sister will definitely become a powerful mage in the future, and she has this potential. ”

Henry touched his sister's head and said to her sternly, "You must be obedient in the future, and don't do naughty things in the Mage Tower." You must know that any magic experiment that goes out of control may lead to the death of a mage. I don't want to see you hurt, if you secretly carry out dangerous real acts, I will immediately drive you home, understand? ”

Lina was taken aback by her brother's words, and then she nodded solemnly. "Don't worry, I won't do things that are beyond my means, only a fool would do that." Henry breathed a sigh of relief when he heard his sister's words. Then he said to Debra, "Lina will be handed over to you later." I think you should understand how to guide. To know for her. I had big expectations. ”

"Don't worry. I understand what it means to be a ten-year-old apprentice. After saying that, she pulled Lina to arrange a room for her.

After seeing the two leave, Henry came to the place where the gray dwarves lived. When Tenoben saw him, he immediately knelt down and asked, "Master, do you have any instructions for coming here?" ”

Henry looked around and saw that it had been divided into small rooms, and the gray dwarves had begun to form their own families. "Tenoben, have you seen that waterfall outside the Mage Tower?"

The Grey Dwarf leader nodded. "Yes the hosts, it was spectacular. You can't see that when you're underground. ”

"I want to build a dam, I don't know if you can do it." Henry made his own request directly. He had always wanted to build a small hydroelectric power station. With a lot of technology on this earth, it can be harnessed. He has already thought of a series of scientific and technological research and development plans, all of which must use electricity.

Tenoburn lowered his head and thought for a moment, then began to crouch on the ground and draw. It was a dozen minutes before he stood up. "Master, I just calculated. If you want to build a dam of more than ten meters, you need the power of the Mage Tower to do it. Because the river outside is so fast, if the levee is too high, it is likely to be washed away the moment the water is released. ”

Henry thought about it for a while, and felt that it was safer to accept his construction and use magic reinforcement. "You'll start blocking the river tomorrow with someone, and I'll give you the blueprints for the dam in a few days. When it is completed, the power of the Mage Tower will be used to turn the entire dam into a huge rock. ”

The leader of the gray dwarves breathed a sigh of relief. He was afraid that Henry would be as unreasonable as the Mind Flayer or the Dark Elves underground. "Understood, I'll lead everyone to work tomorrow. In addition, the wooden giant crossbow you asked for has already been made. They were all in Workshop 2, which was now full. ”

"Got it, I'll do my best to send someone to transport these things away. You've been on a good table lately, and you've doubled your drink supply from tomorrow. With that, he left the underground and went to his workshop. When the grey dwarves heard the news of the doubling of their drinks, they burst into cheers, and they hadn't drunk them in a long time.

Arriving at the workshop, Henry immediately took out a piece of parchment and began to design the structure of the dam. According to his idea, there should be at least 20 meters of drop, and when the time comes, three hydroelectric generators of about 500 kilowatts will be built. According to the drop flow rate of the river outside, it can store about 8 million kilowatt-hours of electricity a year. It took him more than a day to draw the drawing, and then asked the golem to deliver it to Tenoben.

In the days that followed, Henry spent the rest of his time building hydroelectric generators, except for checking the progress of the dam every day. Tenoben soon led the grey dwarves to stop the river, and they slowly began to build the embankment with a large amount of stone and earth. More than two months have passed in the blink of an eye, and the entire dam has been basically completed.

When Henry got the news, he immediately commanded the Golem to install several hydroelectric generators at the gate, and then he called on one-third of the energy reserves of the Mage Tower, turning the entire dam into solid rock. Finally, he connected the cable from the underground of the Mage Tower to the generator. After checking it himself and finding nothing wrong, he informed the gray dwarves to open the blocked river. The high-speed water crashes violently down the river and gushes out along the pre-designed gates. Driven by the flow of water, the generator spun rapidly, and the electricity was continuously transmitted to the elemental pool of the mage tower for storage.

Henry's face was full of smiles when he saw the success of his design, and he could finally start working on something high-tech. The dramatically increased energy within the mage's tower soon caught the attention of Amy and Debra. When the two men came to the river, they saw a huge dam and a high-speed rotating generator.

Debra couldn't wait to step forward and ask, "Master, is it the energy generated by these devices?" ”

"Yes, but I don't know exactly how it works right now. If you are interested, you can go to the library to find electricity-related materials, which have detailed explanations. Henry answered Debra's question in a cryptic way, he didn't want to popularize science in public.

The female mage secretly wrote down these terms in her heart, planning to go to the book and find them out in a while.

Amy walked over with a smile and asked, "Master, can we increase our daily energy ration appropriately in the future?" ”

Henry nodded. "No problem, but don't go too far, I have other uses for this energy. Now let's go back and summon a few water elementals to guard this place, I don't want this dam to be destroyed by anyone else. With that, he returned to the bondage of the Mage Tower.

Ten minutes later, Henry connected to the water elemental world, and many water elements were attracted to him. He carefully communicated with the elemental creatures, and it took him a while to come to an agreement. After opening the portal, these water elementals were summoned, and he took the guys to the vicinity of the dam. Seeing that the water elementals began to patrol the river, Henry returned to the Mage Tower to continue his research.

As soon as Debra returned to the Mage Tower, she plunged headlong into the library, finding all the books on electricity hidden on the last shelf. In the past, she had never looked down on these books that could not raise the level of a mage. However, since seeing the increase in the energy reserves of the Mage Tower, she has become interested in this knowledge.

With an abundant supply of energy, everyone, including the apprentices, increased the number of trials themselves. Henry even plunged headlong into the notes of the black robe of Hylast, and began to study how to increase his casting speed. As the days passed, his casting speed increased dramatically. Now it has been recognized by the system, and the cast speed is -1. After reading all the books about electricity, Debra would go to the dam every day to observe how the generator was working.

Just as autumn was approaching, Robert had the news that the harpists had established a secret base in the city of Bluvent. After getting the news, Henry immediately put down everything and went straight to the location of the thieves' union. As soon as he saw Robert, he immediately asked, "Where are the harpists' strongholds, how many of them are there, and what is the specific purpose?" ”

The leader of the thieves pulled out a map from his body, pointed to a building, and replied, "Right here, all half-elves." There weren't many of them, probably less than ten of them. I didn't make any big moves after I came here, just occasionally inquired about news. I think these people might just be tasked with spending, and I'll be able to kill them all tonight if you need to. ”

Henry shook his head at Robert's words. The Harpists League is a huge organization, and their backstage is made up of the Goddess of Magic's elect. Being hostile to it is clearly the most stupid option and is not in one's own interests. After thinking for a while, Henry said to Robert, "Don't act rashly for the time being, just spy on their movements." I'll find a time in the next few days to visit in person and see what the purpose is. ”

Robert looked at him with some concern. "Master, you'd better bring more people with you when you go, I'm afraid they may be unfavorable to you."

Henry nodded when he heard this, and he felt that Robert had a point. You must know that any large organization like the harpist is a mixture of all kinds of spies. Although he has a little friendship with Kelburn and Layla, he can't stand the deliberate instigation of someone behind him. After making up his mind, he said to Robert, "Come with me tomorrow morning, and I'll see what these guys are up to." ”

"Rest assured, I've arranged for quite a few people to be around this building. If they dare to do it, they can kill them all in a matter of minutes. I've arranged two of the giant crossbows you gave me, facing the gate of the house. ”

Henry patted him on the shoulder with satisfaction. "I'll leave the security issue to you tomorrow, I hope nothing goes wrong." (To be continued......)
