It turned out to be this matter, Huo Yuhao suddenly said gratefully: "Thank you, Qiuqiu." Then I'll go back and ask the senior brother if he can allow me to go. ”

Nan Qiuqiu nodded and said, "Okay, then I'll go find my mother too." Ask her if she has had time lately. Hey, the territory of our sect has been occupied by the Sun and Moon Empire, so if you go back, you have to be careful. ”

Huo Yuhao smiled and said, "It's okay, it's not Longtan Tiger's Den." We've even broken through the Death Soul Guide, are we afraid of the ordinary army of the Sun and Moon Empire?"

Nan Qiuqiu smiled and said, "Senior Brother just finished teaching you, and you got carried away again, aren't you afraid that I will sue you?"

Huo Yuhao smiled: "Don't be afraid, you are not that kind of person." Qiuqiu is the most righteous. ”

Nan Qiuqiu snorted and said, "It seems that I can only be a brother with you in this life." ”

Huo Yuhao laughed and said, "It's good to be a brother! You see, I'm very good to my brothers." Okay, I'll go find Mr. Xuan first, and we'll talk about it later. ”

In the next few days, Huo Yuhao completely entered busy mode, and the discussion between him and Xuan Ziwen took more than three hours, and then he devoted himself to the development of the customized soul guide shell. This task Xuan Ziwen handed over to him directly, and in Xuan Ziwen's words, with his ability, it couldn't be easier to complete this task.

As for going to the Earth Dragon Gate, Bei Bei explained that after he completed this task, he could go.

During the break between the practice, Huo Yuhao wanted to go to Seagod Island again and ask Xuan Lao about the problems he had encountered in his previous cultivation. It's just that after committing himself to the real yàn, he can't extricate himself. It wasn't until half a month later, when the whole practice was completed, that he could be regarded as freeing up his time.

The low-cost fourth-level customized soul guide cannonball is completed. Compared with the normal fourth-level fixed soul guide projectile, its power is only about two-thirds, but the range is almost the same. This is determined by the material itself. And. To be able to do this, even Xuan Ziwen is already amazed.

Huo Yuhao used some small tricks, among them. The most important point is to install the delayed trigger device of the soul guide projectile.

When firing a fixed soul guide projectile, it generally relies on the jet of its own tail. Reach a long-distance explosion. Among them, the push device and the power device should be distinguished, separated by high-strength rare metals. The more powerful the Soul Guide Projectile, the more precious the rare metals that need to be used to isolate it.

However, in Huo Yuhao's design this time, he did the opposite, and he used a new trigger technology.

First of all, because this kind of fixed soul guide cannonball is specially designed for the Zhuge God ballista, so. Huo Yuhao made full use of the jetting ability of the Zhuge God Ballista.

The Zhuge God Ballista itself can push the fixed soul guide cannonball out of a distance of about two kilometers, and within this distance, if the fixed soul guide cannonball is triggered. There is no doubt that energy is wasted.

Huo Yuhao did not use dual regions to make soul guide shells, but purely single regions. At the bottom of the custom-installed soul guide shell, he used some principles of the machine to make a delayed trigger device.

When the fixed soul guide cannonball is fired by the Zhuge God Ballista, it will be triggered by itself. But because there is no push device, then it should be a power device explosion.

However, with the delayed trigger, the speed of departure from the power device is slowed down. This process took about a few seconds, and within a few seconds, the fixed soul guide shell itself was pushed out more than two kilometers away. Then when the power device is detonated, the triggering device in the middle of the machine bracket has a function, and inside the power device, it is divided into two stages, part of which is the secondary push device. This secondary push device will push the fixed soul guide projectile to accelerate again, reaching the speed of the original fourth-level fixed soul guide projectile, and fly into the distance. Because with the initial ejection velocity, it only needs to complete the acceleration. In this way, there is a huge energy saving. Although the power of the final power device has been weakened due to the reduction in size, don't forget, the shell and bracket of this custom-installed soul guide cannonball are all made of iron spirits! It is extremely difficult to be able to do this.

The power of such a fourth-level fixed-fit soul guide cannonball is two-thirds of the normal, but the cost is only one-tenth. This is still without considering the premise that rare metals have a price and no market. It is indeed possible to promote production on a large scale.

Of course, Huo Yuhao's research is nothing more, and it is difficult to achieve more powerful fixed-mounted soul guide shells above level five with this method, because the power is too great, and rare metals are still needed as shells. However, borrowing from Huo Yuhao's method, it can undoubtedly also save materials for higher-level custom-mounted soul guide shells on a certain course.

Finally finished, Huo Yuhao reported his achievements to Bei Bei with a disgraced face, and sat on the chair in front of Bei Bei with an excited face and drank water. In the past half a month, he has been exhausted.

Looking at Huo Yuhao's excited face, Bei Bei couldn't help but smile slightly, after Huo Yuhao and the others came back, they shared a lot of workload for him, and he was a lot more relaxed in the past half a month.

"Yuhao, since it has been completed. When are you going to leave?" asked Bebe.

"Where are you going?" asked Huo Yuhao suspiciously.

Bei Bei was speechless for a while, and said, "Your memory has a tendency to deteriorate! Have you forgotten to promise Qiuqiu? It can't be delayed again and again. You go and see, if it's a high-grade rare metal, just get it back. ”

Huo Yuhao remembered the conversation he had with Nan Qiuqiu that day, scratched his head embarrassedly, and said, "Okay." Senior brother, then I'll go in two days. ”

Bei Bei said: "Okay, then two days later, you can also take a break in the past two days." In the future, I can't study day and night. Look at Mr. Xuan, now the whole thing is a soul guide maniac. ”

Isn't it, Xuan Ziwen has now become the busiest person in the entire Shrek City, but it is strange to say that in this busyness, he has finally broken through the Title Douluo level, and is currently developing his unique ninth-level soul guide, once his development is completed, then, he will be an official ninth-level soul master, and he is also a more powerful existence than the average ninth-level soul master.

Huo Yuhao smiled and said, "You can't rest, but you can't rest." I had some questions in my cultivation before, so I just went to ask Xuan Lao in the past two days. Senior brother, if there is nothing to do, I will leave first and go directly to the Poseidon Pavilion. You're going to find me, and someone should call me over there. ”

After saying that, he ran out in a hurry. Every minute counts so much to him right now.

In the past half month, his soul power has increased by another level, and he is now a seventy-fourth-level control zhì system battle soul saint. This improvement is the result of his accumulation, coupled with the research on the soul power of the beast god these days.

Because he has been doing real things, Huo Yuhao didn't take a closer look at the previous cultivation experience, and now that the real yàn is over, it's time for him to work hard in that direction.

"Yuhao, wash and change your clothes before you go. Bei Bei shouted behind Huo Yuhao with a smile.

"Got it. Huo Yuhao agreed, and the person was gone.

Bei Bei smiled and shook her head helplessly. Lean gently on the back of the chair. Suddenly, as if he remembered something, he opened the drawer in front of him and took out a small jade box from it.

In the jade box, there was a faint pink light circulating. This was given to him by the Youxiang Qiluo Immortal at the beginning. It is one of the two key natural treasures to save Xiaoya. It's just that, to this day, there is still no trace of the Blue Silver Emperor.

Xiaoya, where are you and how are you now?

As soon as she thought of Xiaoya, Beibei's eyes became gentle, but in the gentleness, there was still deep worry. There had been no news from Tang Ya for such a long time, and there was no doubt that she must have been completely affected by those evil soul masters again and lost her mind.

Bei Bei really wanted to look for Xiaoya regardless of it. He had secretly decided in his heart that after the equipment of the three soul master groups was completely built this time, he would leave the Tang Sect to find Xiao Ya, no matter what the price was, even if he couldn't find the Blue Silver Emperor, he would have to bring Xiao Ya back first.

Out of the Tang Gate, Huo Yuhao went straight to Shrek Academy, and now the academy can be said to be in the inner city. Although Shrek City has expanded, Shrek Academy has not, but the Soul Guide Department has added a real space outside.

At present, the continental war has appeared, and even Shrek Academy is no longer absolutely safe, and the number of new students is decreasing except for the students who are already studying in the academy. This is true even for Shrek Academy, let alone other academies.

Entering the academy, Huo Yuhao went straight to Poseidon Island. When I arrived outside the Poseidon Pavilion, after bowing to the Golden Tree first, I went to find Xuan Lao.

Xuan Lao's complexion seemed to be a little better than the last time they met, and asked Huo Yuhao to meet him directly in his room.

"Xuan Lao. Huo Yuhao came to Xuan Lao excitedly, "My real yàn has succeeded." We can now start making low-cost fourth-level custom soul guide shells. If this thing is mass-produced, we will definitely be able to bring a big surprise to the Sun and Moon Empire. ”

"Oh, did you really succeed? You kid is really a genius!" Xuan Lao said in admiration, it has only been a few days, Huo Yuhao has completed such a feat of research. And it can't be copied by the Sun and Moon Empire.

After Huo Yuhao began to study, Bei Bei reported to Xuan Lao at the regular meeting of the Seagod Pavilion.

At the beginning of the war, Shrek Academy was no longer calm, and the Poseidon Pavilion meeting, which was rarely held once a year, was now held once a month, and if there were special circumstances, it would be increased-

Ask for a commuter pass or a recommended ticket.
