Another day passed, early in the morning, Lin Jiayi took Huo Yuhao and slowly walked towards the sixth-grade teaching building.

"Huo Yuhao, congratulations. You are very honored to be appreciated by the Hall Master, and in view of your Soul Guide Machine, the Academy has made an exception to allow you to enter the sixth year, and will arrange for you an excellent teacher of the eighth level of the Soul Master. ”

"When you pass his assessment, you will be eligible to enter Mingde Hall to study."

Lin Jiayi said with a smile.

"However, all these resources are not given to you in vain, you have to assist him in the in-depth study of the subject of the soul guide machine, if you can have relevant research results, the academy will provide you with a rich reward."

Huo Yuhao replied: "Thank you, Director Lin. ”

Although he said yes, no one knows what he thinks in his heart.

There are only two teaching buildings in the sixth grade, but there are only dozens of students, and they can use various metal materials in the experimental area at will, which shows that the college attaches great importance to them.

Lin Jiayi took Huo Yuhao straight to the fifth floor of one of the moves, and stopped in front of a gate marked "Third Laboratory".

He stretched out a nameplate and sensed it in front of the door, and the door opened automatically, revealing a spacious laboratory in front of him.

The laboratory was large, with a variety of soul guides and metal materials, and a large lab table in the center of the room.

At this time, a young-looking, but thirty-year-old teacher was sitting at the experimental table, observing the soul guide in his hand, frowning and meditating, deaf to Lin Jiayi and Huo Yuhao who entered the laboratory.

Lin Jiayi coughed: "Teacher Xuan, good morning, this is the classmate Huo Yuhao I mentioned to you last night." Huo Yuhao, this is Teacher Xuan Ziwen, you will study with him in the future. ”

Lin Jiayi didn't mention the exchange student, Jing Hongchen instructed him to temporarily regard Huo Yuhao as a Sun and Moon student, but he still had to keep monitoring in the short term until he confirmed that Huo Yuhao was no longer suspicious.

Hearing Lin Jiayi's words, Xuan Ziwen didn't look back, but just said indifferently: "Director Lin, you know that my recent research has fallen into a bottleneck, and I don't have the energy to bring new students. ”

Xuan Ziwen and Lin Jiayi are both eighth-level soul masters, although Lin Jiayi is the teaching director, Xuan Ziwen did not give him the slightest face.

Lin Jiayi smiled and said: "Teacher Xuan, you must know that this Huo Yuhao is the student who designed the fourth-level soul guide and the soul guide machine tool, and you should have seen the replica of the design drawings last night." ”

Hearing this, Xuan Ziwen put down the test item in his hand, and turned his head to glance at Huo Yuhao.

He stopped his gaze on the fourth-level soul master badge on Huo Yuhao's chest for a while, and said, "Director Lin, I admit that the drawing is very exquisitely designed, are you sure that he has the ability to design it?" ”

Lin Jiayi affirmed: "That's natural, the hall master and I have already confirmed it face to face." ”

"The hall master assigned him to you, and he also wants you to lead him to conduct an in-depth study of the soul guide machine."

Xuan Ziwen looked Huo Yuhao up and down, deep in thought.

Lin Jiayi had actually come to the door to talk to him last night, and he couldn't help but be stunned for a while when he first heard about it.

Huo Yuhao spoke out at the right time and said respectfully: "Teacher Xuan is good." ”

Xuan Ziwen nodded and looked at Lin Jiayi: "Okay, I know, Director Lin, you can leave him here." ”

"I hope you get along." Lin Jiayi didn't stay long, turned around and left the laboratory.

Xuan Ziwen took out a copy of the drawings of the soul guide machine tool, and then took out the real machine tool that Lin Jiayi handed over to him last night, and looked at Huo Yuhao with interest.

He asked, "Very good design, Huo Yuhao, I'm quite optimistic about you." You must know that the current young soul masters are almost all stupid people who can only copy. ”

"Even many sixth-level soul masters can only make them, and they can't design a new fourth-level soul guide at all."

"Can you tell me why you came up with the idea of using a bottle as a power source for your soul guide?"

Huo Yuhao replied naturally: "Teacher Xuan, isn't the soul power in the bottle originally imported by people?" I'm just lazy and don't want to stay with the soul guide all the time, so it's just too much. ”

Teacher Xuan scolded with a smile: "It seems that you seem to be a little guy who likes to be lazy." ”

Huo Yuhao smiled calmly: "If you want to be lazy and want a more convenient life, isn't it one of the driving forces that promote the development of science and technology?" ”

Xuan Ziwen was stunned for a moment, nodded and smiled: "You are right, you have done this too much for a while, but in the future, you may have the conditions for future generations to be lazy." ”

"I'm working on a technique to seal the bottle, so that the soul power can be stored in the bottle and never dissipate."

"As long as I realize this technology, then I can unconditionally charge the soul guide, so even ordinary people can use the soul guide and enjoy the portability brought by the soul guide."

Huo Yuhao looked at him with some surprise and said, "Teacher Xuan, I have always believed that in the future, the threshold for the use of soul guides will definitely be lowered to the point that even ordinary people can use them. You will succeed! ”

Xuan Ziwen was stunned for a moment, and a smile appeared on his originally stray face: "I didn't expect that you, this little guy, could understand me." Okay, then I'll take you as a student. ”

It is undeniable that although Mingdetang has indeed developed many soul guides for war and combat, in the research and development process of these military science and technology, many scientific research results will inevitably flow to the civilian field.

The end result is a higher standard of living for all people.

Yesterday, when he heard that Mingdetang had such an original intention, and today he saw Xuan Ziwen who had such an idea, Huo Yuhao couldn't help but praise them a few words in his heart.

Huo Yuhao and Xuan Ziwen started a conversation, mainly because Xuan Ziwen asked questions, asking Huo Yuhao's design concept and soul guide concept.

Like yesterday's Jing Hongchen, Huo Yuhao's many thoughts and decrees he couldn't help but be amazed.

Xuan Ziwen took off the milk bottle inserted in the soul guide machine and injected his soft soul power into it. After two days of placement, the soul power in the bottle has long been empty.

Soon, Xuan Ziwen reinserted the filled bottle into the soul guide machine, and put an ordinary piece of metal against the tip of the carving knife.

"Genius idea." Xuan Ziwen looked at the soul guide machine tool that was running again, and commented nonchalantly, "It's a pity, I'm not very optimistic about it for the time being, if you want to study it in depth, there are too many problems that need to be solved." ”

Huo Yuhao frowned and asked, "Why?" ”

"It's quite simple, you've all underestimated the complexity of the high-level core circle." Xuan Ziwen said calmly, "Although your fourth-level soul guide can already engrave a simple core array, just in order to engrave this simple core array, you have embedded dozens of core arrays in this machine tool. ”

"If you want to increase the level of the core circle to be inscribed, such as superimposing five different core circles, then the core circle to be embedded must be far more than five times."

"Because the density of these core circles is too high, if you want not to make mistakes, you must carry out very complex and rigorous planning."

"Either increase the volume or reduce the number of core circles, in short, the difficulty must increase exponentially. In the short term, it will definitely not be solved. ”

Hearing Xuan Ziwen point out his shortcomings, Huo Yuhao fell into deep thought.
