Taking out the blank paper, he immediately began to sketch simply.

If you want to make a complex soul guide, you must first list the requirements, and then list the solutions, the third step is to build all the required magic circles according to the solutions, and the fourth step is to let the magic circles match each other, and in the process of matching, try to keep the effect as much as possible and streamline it. The fifth step is to run in the drawings.

After these five steps, you can start trying to make the core circle. Then, according to the core circle, the shell is made and studied, and the whole process is quite complicated.

Although Huo Yuhao successfully made the eighth-level decomposition cannon at the beginning, in fact, he was still quite far from the eighth-level soul master, first of all, in terms of drawings, but Xuan Ziwen provided him with the drawings at that time.

Xuan Ziwen muttered to himself while drawing the drawings, "First of all, the material selection, since our alchemy furnace is level nine, we must fully consider the material bearing problem of the alchemy furnace itself." While the core circle can generate energy compression and blocking, the materials on the outside also need to be tough enough and have good insulation. At the same time, it is also necessary to be good at thermal conductivity ......"

Huo Yuhao stood aside, looking at Xuan Zi's drawings and listening to him carefully. These words were obviously spoken to themselves.

In research, time always flies.

Xuan Ziwen is worthy of being a ninth-level soul master, but at the end of the day, with Huo Yuhao's mental strength, he felt that he was a little dizzy, and he had to meditate to recover his energy, but Xuan Ziwen still devoted himself to research, and the drawings were already thick with drafts.

The complexity of the ninth-level soul guide far exceeded Huo Yuhao's expectations, the ninth-level soul guide itself was composed of multiple eighth-level soul guides, which not only involved the knowledge of the space system, but also the time system and so on. Every detail is very different from Huo Yuhao's cognition in the past.

Moreover, in the process of making a ninth-level soul guide. The rare metals used are all treasures, and each one is very difficult to carve, not only requiring soul power, but also a combination of soul power and spiritual power. The complex core circle. Even with Huo Yuhao's strong mental power, his heart was full of shock when he saw it, and his brain was completely dizzy.

What Xuan Ziwen said, he couldn't understand everything. And Xuan Ziwen didn't seem to care about this, he told it like a cramming, and he didn't repeat it, leaving it to Huo Yuhao to understand. Only occasionally would he ask Huo Yuhao a sentence or two, and if Huo Yuhao answered correctly, he would continue to speak, and the answer was wrong. The dog's blood spray that will be scolded immediately.

In the blink of an eye, three days have passed, and the prototype of the drawings has been made. Xuan Ziwen has already begun the fourth step of making the drawings, the streamlining and integration of all the core circles.

This combination is not for the sake of making a core circle in the end, but to streamline it. Make the core circle as simple as possible. The difficulty of making zuò is reduced.

Of course, this is also only relative. The production of a ninth-level soul guide is all painstaking and painstaking.

It will be even more difficult to make a ninth-level custom-installed soul guide cannonball, because in addition to the complexity of the ninth-level soul guide projectile, in order to pursue the ultimate, the ninth-level fixed soul guide cannonball also has to set all the core magic circles to the limit. Let it generate maximum power when it erupts. Therefore, in the process of making zuò, there is a possibility of an outbreak at any time.

"Yuhao. There was a low call outside. Huo Yuhao, who was standing beside Xuan Ziwen, turned his head to look, only to see He Caitou waving to him at the door.

Huo Yuhao glanced at Xuan Ziwen, and Xuan Ziwen waved his hand at him, motioning for him to go by himself. But Xuan Ziwen's eyes were always on the drawings.

Huo Yuhao hurriedly ran over. came to Hecaitou, lowered his voice and said, "Second senior brother, what's the matter?"

He Caitou said in a low voice: "I came to see you, you and Teacher Xuan have been in for three days." You should also pay attention to rest when you should take a break, and you should also remind Mr. Xuan. This is the senior brother who asked me to sue you. And there is. Don't forget that you're going back to the academy the night after tomorrow, and Senior Sister has sent someone to remind you today. ”

"Oh, oh. Huo Yuhao remembered that he also promised Zhang Lexuan to attend the blind date conference, and at the same time to get a graduation certificate.

Patting his forehead, Huo Yuhao said: "Fortunately, you came to remind me, otherwise I really forgot, thank you! ”

He Caitou smiled and said, "My brother, thank you for what." What are you and Teacher Xuan studying?"

Huo Yuhao said: "Alchemy furnace." "Although Bei Bei didn't let him talk about refining pills, this refining alchemy furnace was nothing.

He Caitou said curiously: "What is the alchemy furnace for?"

Huo Yuhao said: "To refine the elixir, Teacher Xuan wants to make a high-level alchemy furnace. In the future, refine the elixir for our Tang Sect disciples to take to enhance everyone's cultivation speed. ”

He Caitou's eyes lit up, and he said, "That's really good, seeing that your cultivation has improved so fast, I'm in a hurry!"

He Caitou is a food-based battle soul master, and the more a food-based soul master cultivates in the later stage, the more difficult it becomes, and the improvement of soul power is much more troublesome than that of ordinary soul masters. But if there is a combination of drugs, it will naturally be easier. In this regard, He Caitou is not excluded at all, he himself is a soul master, and most of the soul masters rely on drugs to improve. Of course, it's a good thing to have medicine to eat. If he doesn't have enough cultivation, it will also affect him to become an eighth-level or even a ninth-level soul master in the future.

Huo Yuhao smiled slightly and said, "Don't worry, when the alchemy furnace is ready, we will start trying." ”

He nodded and said, "Then I'll go back first." I've been so tired of the past few years. However, looking at the finished soul guides, I still have a sense of accomplishment. You and Teacher Xuan should study hard. Little junior brother, your talent is better than mine, you must work hard!"

"Definitely!" Huo Yuhao agreed.

After leaving with Caitou, Huo Yuhao honestly returned to Xuan Ziwen and continued to study the drawings with him.

In the past few days, Xuan Ziwen is still very satisfied with Huo Yuhao, for three days, he has almost never left, and although he often scolds Huo Yuhao, in fact, he is very satisfied in his heart, Huo Yuhao's understanding is extremely high, even more than before, he can always draw inferences from his narration, and sometimes he can even put forward some good ideas that he will be surprised by.

Xuan Ziwen was still very satisfied with having such a smart apprentice, but in order not to make him complacent, his attitude was always not good. For genius, you have to suppress a little, otherwise it is easy to be arrogant.

Huo Yuhao's current comprehension is indeed better than before, and the reason is very simple, because of Wang Qiu'er's sacrificial fusion. Wang Qiu'er gave him the Three-Eyed Golden Lion Fate Skull. The fusion of this skull not only had the effect of improving Huo Yuhao's spiritual power, but also had a great effect on his spiritual development and comprehension. These are all subtle, and Huo Yuhao himself is not completely clear.

In fact, if it weren't for the great increase in his comprehension, even if he took the Heavenly Treasure and fused a large amount of vitality, it would be impossible for his cultivation to be so solid even though he had improved so quickly.

In the blink of an eye, another day passed. Research is too easy to make people forget to sleep and eat, and it wasn't until He Caitou came to Huo Yuhao again that he remembered that he had to go to the academy again.

In this regard, Xuan Ziwen did not stop him at all, and let him go. You always have to get a diploma. The drawings have entered the final stage of integration, this stage is not yet incomprehensible to Huo Yuhao's ability, Xuan Ziwen himself has to think about it, this can not be the slightest mistake, as long as there is a problem in one aspect, it is possible to lead to the loss of all the heavenly and earthly treasures.

Out of Xuan Ziwen's real room, Huo Yuhao took a deep breath, and the fresh air rushed into his lungs, which was indescribably comfortable.

"Second Senior Brother, then I'm leaving, you help me tell Senior Brother, I'll come back tomorrow morning." "It's dawn outside, but after staying in Xuan Ziwen's underground laboratory for several days, he can't even tell the difference between morning and afternoon when he comes out.

He Caitou grabbed him and said, "I said junior brother, are you going to go like this?"

Huo Yuhao said as a matter of course: "Yes! Otherwise, how can I go?"

He Caitou was speechless, "Little junior brother, senior sister said that you have to participate in the Seagod Pavilion blind date meeting this time." You are now the façade of our Tang Sect, look at you, you haven't changed your clothes since you came back, you haven't taken a shower for a few days, and your hair is unkempt. If you just go, I guess I'll let the senior sister call back. Pack up and eat something to refresh yourself. ”

"Uh......" If it weren't for the reminder from Caitou, Huo Yuhao really wouldn't have noticed that there were so many problems on his body, but he hadn't taken a bath for several days, and he had forgotten to sleep and eat every day to study with Xuan Ziwen, and the whole person was immersed in the world of soul guides.

With a red face, Huo Yuhao said, "I'll go back now, thank you Second Senior Brother for reminding me." ”

He Caitou smiled and said: "You, hurry up, senior brother has asked people to prepare clothes for you, you go out, the representative can see our Tang Sect, in order for more students to be willing to invest in our Tang Sect in the future, you also want to be more beautiful this time, remember?"

"Oh, okay. Huo Yuhao agreed, his heart was warm, the senior brother took care of Teacher Xiaoya so hard every day, and he didn't forget his own affairs, this care was really like a brother.
