Shi Xiaoshu's soul was rapidly rising, and the soul power transformed into the Soul Awakening Pill was like a storm, tearing apart Shi Xiaoshu's soul like a storm.

"Woo......"

Shi Xiaoshu gritted her teeth and let out a whining sound.

She kept resisting, and her soul kept growing because of this.

Soon, he broke through to the early stage of the Sand Soul Realm, then the middle stage, and finally, stayed in the late stage.

The whole process lasted five hours, and the pain that Shi Xiaoshu endured in these five hours was endless.

However, the effect is also huge.

Originally, Mu Hai thought that she would only break through to the early stage of the Sand Soul, but she didn't expect that the whole breakthrough to the late stage of the Sand Soul was far more than Mu Hai expected.

"It seems that I also want to learn from her, put her to death and be reborn, and my soul will continue to grow in tears. Mu Hai nodded secretly.

"Brother, what kind of pill did you give me, it hurts me to death. Shi Xiaoshu said.

Hearing this, Mu Hai's head grew for a while, "What do you still say, you swallowed it all without asking, you know, when you are refining, you can swallow at most one at a time, otherwise it will be extremely painful." ”

"What? only one at a time?"

Shi Xiaoshu showed a look of embarrassment, and couldn't help but stick out her tongue.

"Fortunately, you are firm, if you can't, my brother may not be able to save you back. Mu Hai said.

Shi Xiaoshu showed a look of fear for a while, "Brother, I will never cultivate like this in the future." ”

"That's the best, come, here are 20 pieces, you can eat slowly in the future." Mu Hai said.

"Good. Shi Xiaoshu took the jade bottle and carefully received it into the space ring.

Then, Shi Xiaoshu stood up and looked at Mu Hai seriously again, "Brother, can you teach me now?"

"Don't worry, I'll confirm one more thing. ”

After speaking, Mu Hai's mind moved, and he took out a piece of Demon Yuan Crystal.

The moment he saw Mo Yuanjing, Shi Xiaoshu was stunned.

"Hoo ......"

Shi Xiaoshu quickly pounced, snatched the Demon Yuan Crystal from Mu Hai's hand, and then swallowed it in one gulp.

The whole process, done in one go, flowed smoothly, making Mu Hai stunned for a while.

After swallowing it, Shi Xiaoshu showed a look of satisfaction, "Brother, I'm sorry, I forgot that I had it." ”

After speaking, Shi Xiaoshu took out a handful of Demon Yuan Crystal from the space ring, and just as she was about to swallow it in one gulp, Mu Hai quickly stopped it.

"Xiaoshu, eat more leisurely in the future. Mu Hai grabbed her hand and said seriously.

"Brother, I'm sorry, I'm used to it, in order to save time to learn mechanical manufacturing, when I eat, I swallow it in one bite. Shi Xiaoshu said embarrassedly.

"Xiaoshu, this is not rice, this is the Demon Yuan Crystal, you swallow dozens of pills in one bite and don't want to die?" Mu Hai shook his head for a while.

"Brother, I'll pay attention to it later. ”

Shi Xiaoshu said with a look of grievance.

"Hmph, this is no joke, with your current cultivation, you can bear up to 5 at a time, understand?" Mu Hai said.

"Yes. ”

Shi Xiaoshu nodded, grabbed 4 of them, and swallowed them in one gulp.

In her dantian, the number of demon yuan is increasing rapidly, and if it goes on like this, it won't take half a day for the demon yuan to fill her body.

However, she is still an immortal and demon dual cultivator, it's just that the immortal cultivation physique is very ordinary, as long as she continues to cultivate according to the cultivation method given by Mu Hai, her strength will not be too weak in the future, and it is not impossible to comprehend a great avenue.

"Okay, now let's learn mechanical engineering with me. Mu Hai said seriously.

"Brother, you're so good, you're finally willing to teach me. Shi Xiaoshu looked happy, grabbed Mu Hai, and kept jumping.

"Alright, sit down first. ”

Mu Hai said seriously.

"Yes. ”

Shi Xiaoshu showed an extremely serious look and sat opposite Mu Hai.

"This is the mechanical manufacturing I realize, you first have a good understanding, and then, I will seriously teach you to make a war gun. Mu Hai said.

"Yes. Shi Xiaoshu nodded heavily.

Then, Mu Hai's mind moved, and he used his mechanical manufacturing related memories to use his divine sense to directly transmit them to Shi Xiaoshu's mind.

Sensing Mu Hai's divine sense, Shi Xiaoshu was stunned.

It turns out that this is machine building.

What she had learned before was nothing compared to these.

No wonder, my brother said that those mecha in the country were garbage, and I was still disdainful at the time, if I hadn't thought about revenge at that time, I might have counted my brother hard.

Thinking of this, Shi Xiaoshu broke out in a cold sweat, and the secret road was dangerous.

If that's the case, I'm afraid that I'll get embarrassed and have no face to see people again.

It took a long time for Shi Xiaoshu to come back.

She looked at Mu Hai in surprise, her face was full of joy, admiration, and surprise......

"How do you feel?" Mu Hai asked.

"Brother, I've only skimmed it a little, but I have a good impression of the Xianyuan battle gun. Shi Xiaoshu said.

"That's good. ”

Mu Hai nodded, "The aura battle spear I refined is the same principle as the immortal yuan battle spear, but the immortal materials needed in this world cannot be found, so I can only replace them with other materials." ”

"Yes, I understand. Shi Xiaoshu nodded heavily.

"Before we begin, I'll pass on to you a set of methods for portraying the transformation formation, which is the most crucial step of the Aura Battle Spear. Mu Hai said.

"Yes. Shi Xiaoshu nodded.

"The formation is ......"

Then, Mu Hai began to explain the formation method to Shi Xiaoshu in detail, and handed over some of the formations he felt to Shi Xiaoshu for mechanical manufacturing.

Shi Xiaoshu listened carefully while feeling it.

When Mu Hai practiced, he studied with him, and he looked extremely serious.

"You see, this is a transformation array, and there are many formations in it, including the Transformation Spirit Pattern, the Gathering Mighty Pattern, and ......"

Mu Hai took a carved formation stone and handed it to Shi Xiaoshu.

Shi Xiaoshu held this formation stone and kept looking, her face was full of light.

"Now that the core components of the Reiki Gun are ready, it's time to build the basic structure.

The aura battle gun, every time it fires, it will make the barrel produce a terrifying high temperature, so it is necessary to have heat-resistant materials.

......”

Then, Mu Hai practiced in person while instructing, and Shi Xiaoshu was dumbfounded.

This process lasts two hours.

"It's done!"

Mu Hai's eyes lit up, looking at the aura war spear in his hand, and nodded again and again.

The Reiki Gun, from the outside, is similar to a sniper rifle, measuring 1.5 meters long, but the difference is that this gun does not have a mount, and in addition, there is a small magazine.

This magazine is used to hold spirit stones, and it can be loaded with 1 kg each time.

The weight of the entire gun added up to less than 100 kilograms, which can be said to be insignificant for Mu Hai.

Finally, it's a little heavier, the Aura Gun has no recoil, and the probability of missing is very low.

"Brother, how powerful is this aura battle spear, do you want to give it a try?" Shi Xiaoshu said with a full of surprise.

"Yes. ”

Mu Hai nodded, picked up the aura battle spear and walked out with Shi Xiaoshu......
