This..." Huo Yuhao realized that he had overlooked such an important issue.

Xuan Ziwen continued: "Second, let me ask you, if the energy of heaven and earth is condensed to a certain extent and compressed within a certain range, what will happen when the equipment used to compress it has limited endurance?"

"This..." Sweat began to flow from Huo Yuhao's forehead.

Xuan Ziwen sneered: "With a 'bang', it will be blown up. You will also be blown up together. Don't you know how much heaven and earth energy is contained in the treasures of heaven and earth? You haven't tasted it, so you can't imagine it."

Really? Do you think you can make medicine with just any stove? It’s really ridiculous! If you don’t solve these two problems, you will only be wasting things."

With that said, he threw the drawing in his hand directly at Huo Yuhao's face, turned around and left.

"Hey! Teacher Xuan, please don't leave! I was wrong, please tell me quickly!" Huo Yuhao couldn't think of how to solve these two problems for a while, so he hurriedly chased after him.

Although Xuan Ziwen was walking in front, there was a strange smile on his face, and he thought to himself: Brat, let me see what else you can do now. Hehe.

When Xuan Ziwen heard Beibei say that Huo Yuhao was going to use heavenly materials and earthly treasures to refine medicine, he guessed that there was going to be a problem in the alchemy furnace. The reason was very simple - when Xuan Ziwen was in the Sun and Moon Empire, he had a connection

The better soul mentor friends are those who are specifically responsible for refining medicine for the royal family.

There are so many soul masters in the Sun and Moon Empire. Why? It's because they can refine a large amount of elixirs for those soul masters who have awakened their soul power but are not very talented, to speed up their cultivation.

In this regard, the Sun and Moon Empire is the authority.

Xuan Ziwen's talent in martial arts was not good either, and he had continuously improved it by taking elixirs.

Some time ago, his cultivation reached the ninth ring, which was also assisted by drugs. Xuan Ziwen discovered that in terms of drugs, although the drugs provided by Shrek Academy were all good, they were all unrefined drugs.

This is undoubtedly a huge waste.

But because he had very important research and was not good at alchemy, he didn't say much.

This time when he heard that Huo Yuhao wanted to refine medicine, he rushed over immediately. He knew that if he wanted to refine medicines of the level of heavenly materials and earthly treasures, the alchemy furnace used must be a high-level soul guide. The higher the level of the medicines refined, the higher the level of medicine.

The higher the level, the higher the requirements for the alchemy furnace. This was the experience told to him by the alchemy soul mentor of the Sun and Moon Empire.

Although Xuan Ziwen didn't know what the heavenly materials and earthly treasures Huo Yuhao brought back were and how high their quality was, he could roughly guess from Beibei's simple description that it would probably take a level nine alchemy furnace to complete the refining!

With Huo Yuhao's current ability, it is obviously impossible to make a ninth-level soul guide. Therefore, no matter how good his drawings are, they will still be dismissed as worthless by Xuan Ziwen. Because the alchemy furnace drawn by Huo Yuhao cannot solve the fundamental problem.

The problem is the suppression of the heaven and earth energy released by the fairy grass. Without enough suppression, the alchemy furnace will only explode.

Huo Yuhao didn't know that Xuan Ziwen had such experience. He was scolded so badly that he chased him out with a smile. Xuan Ziwen killed two birds with one stone.

"Why are you chasing me?" Xuan Ziwen stopped and looked at Huo Yuhao coldly.

Huo Yuhao hurriedly said respectfully: "Teacher Xuan, I was wrong. I will definitely learn how to make soul tools with you seriously in the future." He is a smart man and understands that Xuan Ziwen is doing this for him. And Xuan Ziwen's final result

Can he still not understand the purpose?

Xuan Ziwen snorted disdainfully and said: "If you are willing to learn, do I have to teach you? Aren't you very good at being a soul master? Twin martial souls, ultimate ice, go ahead and be your soul master.

!" With that said, he turned around and left again.

Huo Yuhao quickly blocked Xuan Ziwen's path and said with a smile on his face: "Mr.

Give me a chance to make a new start. Don’t worry, I will study hard with you this time, and I will definitely work hard to become a ninth-level soul engineer in the future, and I will never give up halfway again. Do you think it’s okay?"

Xuan Ziwen's face looked better now, and he snorted and said: "That's pretty much it. Since you are somewhat sincere, I reluctantly agreed. But remember, I want to train you.

This is not to make you a ninth-level soul master. Although the number of ninth-level soul masters is small, it is not the limit after all."

Huo Yuhao said in surprise: "What do you want?"

There was a look of fanaticism in Xuan Ziwen's eyes, which made Huo Yuhao's body get goosebumps.

"In my lifetime, I hope that I can train a tenth-level soul master and truly stand at the pinnacle of soul masters! My talent is limited, and I will never be able to become a tenth-level soul master in this life. But your qualifications are unique, and I believe in you.

You will definitely be able to become a tenth-level soul master in the future. You have to work hard for me. This time, at least until you become a ninth-level soul master, you are not allowed to leave the Tang Sect easily. I will refuse anything you do."

"This..." Huo Yuhao's face suddenly turned ugly and he looked at Xuan Ziwen with a wry smile.

How can it be that easy to become a ninth-level soul master? He must first cultivate to the level of Titled Douluo. That cannot be accomplished in a day or two.

Xuan Ziwen sneered and said, "Don't want to? Then you can do whatever you want." With that, the old man walked away leisurely.

"Teacher Xuan, don't leave!" Huo Yuhao hurriedly followed and said with a wry smile, "Look, I have just touched the door of the eighth ring. How easy is it to cultivate to the ninth ring? What's more, I have to become a ninth-level soul master.

, your requirements are too high, right? I promise to work hard, but can you relax your requirements? Or, an eighth-level soul engineer?"

Xuan Ziwen didn't even pay attention to him and walked forward as if he didn't hear him at all.

Huo Yuhao was helpless. He knew that without the help of Teacher Xuan, he would never be able to complete the alchemy furnace. However, he could not leave the Tang Sect before he became a ninth-level soul master. This condition was too harsh. What if he was lucky?

No, what should I do if it takes ten or eight years to practice?

“Mr.

Shrek City, but if there is something special, especially if the academy requires it, I still have to go."

Xuan Ziwen knew that he could not force him too much, so he nodded and said: "This is okay." Shrek Academy has great support for his research and has a very harmonious relationship with him, and he also knows that Huo Yuhao is a member of Shrek Academy.

One of the members of Poseidon Pavilion, if Shrek Academy wants Huo Yuhao to do something, it's really hard to stop him.

With Xuan Ziwen's words, Huo Yuhao breathed a sigh of relief. Just when he was about to say something, Xuan Ziwen said: "You brat, don't think that I don't know what you have in mind. If you take advantage of Shi in the future,

If you run away from Lake College, don't blame me for being rude to you. I didn't do anything else at that time. I left Tangmen the same way I left Mingde Hall."

"Uh... Teacher Xuan, am I that kind of person? How could I sneak away in the name of the academy? Don't worry, I will study hard with you this time." Although Huo Yuhao felt guilty, he immediately expressed his attitude

.At this time, he didn’t dare to offend Xuan Ziwen at all!

Xuan Ziwen nodded with satisfaction and said: "Okay, then you come with me. We need to design your alchemy furnace carefully. It must be designed to be nine levels in order to be safe."

"Level 9!" Huo Yuhao was really shocked.

Xuan Ziwen sneered and said: "Do you think it is so easy to refine heavenly materials and earthly treasures? This alchemy furnace does not have level nine, and it simply cannot withstand the breath of so many good things. This alchemy furnace must not only have a good sealing effect

, you also need to have a compression effect, and all the details must be taken into consideration. Because you have no chance of failure at all. Can you use Tiancai Dibao for experiments?"

Huo Yuhao really wanted to answer "yes" because he brought back a lot of good things this time, but he didn't dare to say it. How rigorous Xuan Ziwen was!

Huo Yuhao humbly asked for advice: "Teacher Xuan, what should we do?"

As Xuan Ziwen walked, he said: "Let's perfect the design in the past few days. I had a friend who was an alchemist before, and I heard him talk about how to make an alchemy furnace. However, at that time, he didn't

I have made a level 9 alchemy furnace, which is just some ideas. When designing, you must be fully involved. Although your current cultivation level and experience are a little behind, your mental strength is strong enough and you will not be able to read some complicated drawings.

Any questions? When I start casting the alchemy furnace, you will be my first assistant."

"Yes!" Looking at Xuan Ziwen's serious look, Huo Yuhao couldn't help but feel secretly moved in his heart. He knew very well what a precious asset it was to be able to accompany a ninth-level soul master to make a ninth-level soul guide and participate in the whole process!

Zi Wen will definitely guide him carefully throughout the entire process. This kind of experience will be of great benefit to him in becoming a ninth-level soul master in the future.

Huo Yuhao followed Xuan Ziwen to the research room. Xuan Ziwen always worked vigorously and resolutely, especially in the research of soul guidance devices.

He took out the white paper and immediately began to sketch briefly.

If you want to make a complex soul tool, the first step is to list the requirements; the second step is to list the solutions; the third step is to build all the required magic arrays according to the solutions; the fourth step is to make the magic circle

Match each other, and in the process of matching, streamline as much as possible; the fifth step is to run in the drawings.

After these five steps, the soul master can try to make the core array, and then conduct research on the outer shell. The whole process is quite complicated.

Although Huo Yuhao successfully produced the eighth-level decomposition cannon, he was actually still far behind from the eighth-level soul master. This was first reflected in the blueprints. At that time, Xuan Ziwen provided him with the blueprints.

Xuan Ziwen said to himself while drawing the drawings: "The first is material selection. Since our alchemy furnace is level nine, we must fully consider the load-bearing problem of the material. Although using the core array can produce energy compression and

barrier, but the outer material must be tough enough and have good insulation properties, and it must also be good at heat conduction..."

Huo Yuhao stood aside, looking at Xuan Ziwen's drawings and listening to him carefully. Xuan Ziwen's words were obviously meant for him.

In research, time always flies by.

Xuan Ziwen is worthy of being a ninth-level soul master. At the end of the day, Huo Yuhao's mental intensity made him feel a little dizzy, and he had to meditate to regain his energy. However, Xuan Ziwen still devoted himself to research without sleep or food. It was just a draft.

There is already a thick stack.

The complexity of the ninth-level soul guidance device far exceeded Huo Yuhao's expectations. The ninth-level soul guidance device itself is composed of multiple eighth-level soul guidance devices, which not only involves the knowledge of the space system, but also the time system.

Every detail is very different from Huo Yuhao's previous understanding.

Moreover, in the process of making the ninth-level soul guide, all the rare metals used are treasures, and each type of carving is very difficult. It not only requires soul power, but also the combination of soul power and spiritual power. That complex core

Even if Huo Yuhao possessed strong mental power, just one look at the magic circle filled his heart with shock and made his brain completely dizzy.

Not everything Xuan Ziwen told him could be understood. But Xuan Ziwen didn't seem to care about it. He told it like a spoonful without repeating it. He let Huo Yuhao understand it and only asked Huo Yuhao occasionally.

Yuhao asked one or two questions. If Huo Yuhao answered correctly, he would continue talking. If he answered incorrectly, he would be scolded immediately.

In the blink of an eye, three days have passed, and the prototype of the drawing has been born. Xuan Ziwen has already begun the fourth step of the drawing - the streamlining and combination of all core formations.

This step is not just to finally produce a core array, but to make the core array as simple as possible and reduce the difficulty of production through streamlining.

Of course, this is only relative. The production of any level nine soul guide is extremely difficult.

It would be even more difficult to make level 9 fixed soul guided artillery shells. In addition to the complexity of the level 9 fixed soul guided artillery shells, in order to pursue the ultimate level 9 fixed soul guided artillery shells, all core arrays must be set to

limit, so that it can produce the maximum power when it explodes. Therefore, during the production process, the ninth-level fixed soul-guided cannonball may explode at any time.

"Yuhao." A low voice came from outside. Huo Yuhao, who was standing next to Xuan Ziwen, turned around and saw He Caitou waving to him at the door.

Huo Yuhao glanced at Xuan Ziwen, and Xuan Ziwen waved his hand to him, indicating that he could go alone. Xuan Ziwen's eyes were always focused on the drawing.

Huo Yuhao hurriedly ran over, came to He Caitou, lowered his voice and asked, "Second senior brother, what's the matter?"
