However, Huo Yuhao has been sitting here for a long time, and Xuan Ziwen is still very satisfied. At least this kid is not impetuous, and the basic rules are still very clear. With his mental strength and intelligence, he can understand the ninth-level soul guide.

The core magic circle should not be too difficult, which is also an improvement for him.

Observing Huo Yuhao who was sitting there, it was okay for a while, but Xuan Ziwen couldn't bear it as time went by. He almost didn't sleep all night last night, and now he was really sleepy.

So, before he knew it, he fell asleep leaning on the experimental table.

This sleep was quite sweet. The Tang Sect Soul Guidance Hall is now completely on the right track. All Xuan Ziwen has to do is some research of his own, which is a lot easier than before. But even if it is easier, he still has a lot of confidence in his own research.

The requirements are also very high. This is the first time in many years that I sleep like this during the day.

Sleep well and be in good spirits.

When Xuan Ziwen woke up from his sleep, he felt refreshed and very comfortable.

However, when he opened his eyes, he found that there was no one in the laboratory. Yes, Huo Yuhao had gone somewhere long ago.

"Did this little bastard run away?"

In shock, Xuan Ziwen jumped up and rushed out to find Huo Yuhao.

At this moment, the door of the laboratory opened, and Huo Yuhao walked in from the outside leisurely.

"You brat, what did you do? You turned a deaf ear to what I said, didn't you? Didn't you say you're not allowed to go out if you don't do well?"

Huo Yuhao said angrily: "Mr.

, you are still in adolescence, and you need to supplement your nutrition. I just went out to get food, and I brought some food back from the cafeteria, and you have a share."

As he said that, he put the lunch box in his hand on the experimental table, took one box, and ate it.

Xuan Ziwen also immediately took the lunch box and ate happily. Not to mention, the food in Tangmen has always been very good. He slept all morning and then had this delicious meal. It was really comfortable!

Soon, the ladles and bowls were cleaned. In order to show that he was a man who could take things and put them down, Xuan Ziwen took the initiative to clear away the dishes.

While cleaning up, he asked Huo Yuhao: "Have you looked at it all morning? Do you see any clues?"

"Well, it's okay. I'm about to look at the second core array." Huo Yuhao said.

Xuan Ziwen glared at him and said: "If you don't want to bite off more than you can chew, let's finish the first one thoroughly first, and then try to make one. Each of these thirteen core arrays is different, each one..."

As soon as he said this, he couldn't continue because Huo Yuhao had already put a metal ball that looked only about the size of an orange into his hand.

This metal ball is completely hollow, with a faint flash of light inside, and the extremely complex structure seems to be quietly operating in accordance with the principles of heaven and earth.

"This...the first core magic circle, have you already made it?" Xuan Ziwen's voice changed with excitement, just like the sound made by a teenage boy when his voice changed.

Huo Yuhao said matter-of-factly: "Yes! It's not that difficult. I'll look at the second one." As he said that, he picked up the second drawing and started reading it.

Xuan Ziwen held the core array in his hand and quickly searched for it on the experimental table. Sure enough, he found a piece of fine powder, which was exactly what was left when making the core array of the soul guidance device.

In one morning, Huo Yuhao understood one of the core formations of the ninth-level soul guide and completed its production.

This time it was Xuan Ziwen who wanted to vomit blood. Making the core array did not consume as much soul power as making the shell, but the level of precision required was many times higher. Even Xuan Ziwen did not have this ability.

Complete such a core array in a short period of time.

Huo Yuhao actually completed it. This is absolutely impossible!

Xuan Ziwen quickly raised the core array in his hand and used all the methods he knew to explore the status of the core array, sparing no effort to find flaws and problems.

An hour has passed, and there is no problem with this core array!

How can this be?

What happened to Huo Yuhao has completely violated the conventions for the development of soul masters, yes, it completely violated it.

Xuan Ziwen could not believe that this was true. Looking at Huo Yuhao who was carefully studying the drawings of the core array of the soul guide, his heart was twitching. However, this time Xuan Ziwen decided that no matter what, he could not miss Huo Yuhao again.

The process of making the core array. He must see how his apprentice completed such a complex core array. Huo Yuhao must have some special method.

Xuan Ziwen had made up his mind and was very perseverant. He sat there and looked at Huo Yuhao with wide eyes, not missing any small detail.

Huo Yuhao was a little embarrassed by him and couldn't help but glance at him occasionally. However, in Huo Yuhao's eyes, it was obviously the drawings of the core formation that were more charming.

He didn't put down this second drawing of the core formation until the evening.

He stood up, moved his body vigorously, and stretched.

"Have you finished reading?" Xuan Ziwen asked.

Huo Yuhao nodded.

Xuan Ziwen said: "Do you understand?"

"I understand." Huo Yuhao nodded seriously and replied.

"Then what are you waiting for? Why don't you start making it while it's still hot!" Xuan Ziwen roared in a low voice.

Huo Yuhao said with aggrieved expression: "But it's time to have dinner! I'll go get some food first and cook it after dinner."

Xuan Ziwen said anxiously: "Leave the cooking to me!" As he said that, he transformed into a man like the wind and went out with his lunch box.

However, both the master and the apprentice had some deviations in their judgment of meal time. Xuan Ziwen waited in the cafeteria for a full fifteen minutes and urged him for a long time before returning with a meal. In addition to the time spent on the road, he left

It took a full thirty minutes.

Xuan Ziwen was a little depressed, thinking: If I had known it would take so long, I would have let the boy go get food by himself, which would also allow him to relax. I wonder if he has started to make the core magic circle, just start it, that's all.

Lazy, hum!

Xuan Ziwen came back with a lunch box. As soon as he entered the door, he happened to see Huo Yuhao sitting there, shaking his head as if thinking about something, but there was nothing in his hands, which were completely empty.

"Okay, you brat, you really treat the teacher as a coolie, and you didn't even move at all." Xuan Ziwen was furious and threw the lunch box in his hand directly towards Huo Yuhao.

Huo Yuhao was startled and quickly caught it: "Teacher, what are you doing?"

Xuan Ziwen said angrily: "I went to prepare food for you to give you more time to make the core array, not to let you rest here!"

"I did it!" Huo Yuhao said innocently.

"Did it? Where is it?" Xuan Ziwen asked in disbelief.

Huo Yuhao grabbed a metal ball from the table next to him and brought it to Xuan Ziwen: "It's here!"

Xuan Ziwen subconsciously took the metal ball and looked down. It didn't matter. His eyes suddenly widened again. This was...

Not caring about scolding Huo Yuhao anymore, he quickly walked to the side and sat down, carefully observing the metal ball in his hand. A sly smile appeared on Huo Yuhao's face, he put the lunch box on the table and started eating. At the end of the day, he spent

There is really a lot to worry about.

After he quickly ate his lunch, he said naturally: "Teacher Xuan, I've almost finished today's work, so I'm going back to rest. Goodbye!"

"Yes." Xuan Ziwen concentrated on the metal ball and subconsciously agreed. Huo Yuhao ran away as if he was flying.

Xuan Ziwen never remembered that he had said before that he would not let him leave and would always study here. He was really shocked by the metal ball in his hand.

This is the second of the thirteen core arrays of the alchemy furnace.

The complete second core magic circle! As soon as he got it, the soul power fluctuations in this core magic circle clearly told him that there was nothing wrong with this thing and it was exactly what he wanted. He checked the details carefully, hoping

Find a flaw in it. But just like last night, all attempts are in vain. This core circle is done flawlessly, on the same level as the previous one.

How is this possible? How is this possible! This is the second core array of a level nine soul tool!

Although the alchemy furnace is definitely not complex among the ninth-level soul tools, and is only an entry-level ninth-level soul tool at most, it is still a ninth-level soul tool.

Generally speaking, even if a ninth-level soul engineer makes a ninth-level soul guide, it will take three months to half a year to complete if sufficient preparations are made. Because the core formation of the ninth-level soul guide is made.

It is too complicated to make, and mistakes are inevitable during the production process. Once reworked, materials and time will be wasted. Therefore, before making each core magic circle, the soul master must calm down and rest for a long time to ensure as much as possible.

Only when you are in perfect condition can you succeed.

Xuan Ziwen hadn't had time to teach Huo Yuhao this point yet. He originally planned to let Huo Yuhao fail once, and then teach him based on the lessons of this failure, so that he would remember it more deeply. But who knew that Huo Yuhao didn't teach him at all?

This opportunity. Failure? Where is the failure?

The entire core array was made almost flawlessly, and two of them were made in one day. Xuan Ziwen considered himself extremely talented, but he knew that he would never be able to create two completely different core arrays in one day.

.When he is in his best condition, it would be great if he can complete one. After completing it, he still needs to rest for a long time.

Is this kid really human?

Hey, by the way, how did he make it? The process of making rice only lasted thirty minutes, but he actually finished it in such a short time?

Thinking of this, Xuan Ziwen raised his head and shouted: "Yuhao, tell me the truth, how did you do it..." Just when he said this, he realized that there was no one in the laboratory.

Only then did he remember that he had just casually promised Huo Yuhao that he could leave, and he suddenly became angry. This kid really knows how to seize opportunities!

Xuan Ziwen was an activist. A few minutes later, he appeared at the door of Huo Yuhao's room and banged on the door.

It was Tang Wutong who opened the door.

Seeing Xuan Ziwen, she immediately made a silent gesture.

Xuan Ziwen was stunned for a moment and asked in a low voice: "Where is Huo Yuhao?"

Tang Wutong whispered: "He fell asleep. He seemed very tired and fell asleep as soon as he came back." As she said that, she pointed towards the room and opened the door.

Xuan Ziwen glanced inside and saw Huo Yuhao lying on the bed, sleeping soundly and soundly.

It seemed that he was overusing his brain. For some reason, seeing Huo Yuhao in a comatose state, Xuan Ziwen felt a little more mentally balanced.

"Forget it, let's talk about it tomorrow." Xuan Ziwen turned around and left helplessly. There were two people living together, what would happen if he went in? Although he is a research madman, he still knows some human nature, and he can't do it anymore.
