Perhaps because Wu Ming was too famous in the Inner Courtyard, the result of Wang Nan's battle with her spread throughout the Inner Courtyard within half a day.
The next day, the Inner Courtyard's ranking list was updated. After his battle with Wu Ming, Wang Nan's rank in the Inner Courtyard jumped to fifteenth place. Now, most of those ahead of him were Inner Courtyard Disciples with Spirit Douluo or Spirit Saint cultivation.
Fortunately, not everyone witnessed that battle, so many Inner Courtyard Disciples didn't know what Wang Nan looked like, which prevented him from attracting too many stares when he went out.
Wang Nan made his way to the Soul Guidance System in the Inner Courtyard. As soon as he entered, he saw Ye Xiaosheng mysteriously approaching. As a future official participant in the Soul Duel Tournament, Ye Xiaosheng had also successfully entered the Inner Courtyard.
"Hello, Senior Brother Wang," Ye Xiaosheng greeted with a peculiar tone.
Hearing Ye Xiaosheng's words, Wang Nan couldn't help but smile. The two had interacted frequently when they were in the Outer Courtyard, and now that they were in the Inner Courtyard, Ye Xiaosheng's address of "Senior Brother" held more of a teasing meaning.
Lin Xiao, who had made the spirit tool thruster for Wang Nan, had passed the sixth-grade promotion assessment but ultimately failed to enter the Inner Courtyard. After that, Wang Nan would always consult Ye Xiaosheng for any matters regarding spirit tools.
Now that Wang Nan's cultivation had reached Spirit King, he was no longer quite satisfied with the speed of a Rank 3 spirit tool.
"Alright, stop fooling around and help me take a look at this," Wang Nan said, pulling out the spirit tool thruster he always wore.
"Ah, I remember this. You 'whooshed' past me with this thing and defeated me back then," Ye Xiaosheng said, turning the spirit tool thruster over and over, a little emotional. "But it doesn't seem to have any problems. What do you want me to look at?"
"See if you can help me upgrade it, or make another one just like it, preferably at the level of a Rank 5 spirit tool."
Ye Xiaosheng glanced at Wang Nan. "Simply increasing the speed isn't difficult, but you have to understand that the stronger the thrust of a spirit tool thruster, the more it tests your physical strength. Otherwise, you might not be able to withstand even a slight acceleration yourself."
Wang Nan nodded. Although he hadn't learned to make spirit tools, he knew some basic things.
"Don't worry, it's no problem."
"Sigh, sometimes I really envy you Spirit Masters. Don't look at me, I'm a Rank 5 Soul Master now, but without Spirit Ability bonuses, I'd have to be very careful using a Rank 3 spirit tool thruster like this." Ye Xiaosheng put away Wang Nan's spirit tool thruster.
"Upgrading this spirit tool thruster will definitely be better than making a new one, especially since you've used it for so long. A new spirit tool might not be fully adaptable in a short amount of time. So, leave it with me for now, and I'll find you once the upgrade is complete."
"Okay, then I'll look forward to your good news." Wang Nan nodded, then suddenly remembered another matter. "How's the research coming along for that spirit light ray I told you about last time?"
Ye Xiaosheng shook his head. "You only told me its effect. I can't recreate it based on just that. And from what you said, being able to track targets and having considerable power, it sounds like it's in the realm of Rank 7 spirit tools. Even if you put its prototype in front of me, I might not be able to figure it out."
"And it's not just me; even the academy's teachers would find it very difficult to make the kind of spirit tool you're talking about. Where exactly did you see that kind of spirit tool? You didn't run off to the Sun Moon Empire, did you?"
Ye Xiaosheng looked at Wang Nan with some confusion.
What Wang Nan had told Ye Xiaosheng about was the spirit light ray used by the Spirit Douluo who had pursued Dai Yueheng last time. Now, from Ye Xiaosheng's words, that Spirit Douluo should have come from the Sun Moon Empire.
Could it be that the White Tiger Duke had fought too fiercely on the battlefield between the Star Luo Empire and the Sun Moon Empire, so the Sun Moon Empire was seeking revenge on the White Tiger Duke's child?
"No, I didn't see it in the Sun Moon Empire." Wang Nan shook his head, saying no more.
"That's good. The Sun Moon Empire has never been very friendly to our Shrek Disciples." Ye Xiaosheng didn't press further, but instead changed the subject, talking about other things. "However, I tried making some of that other spirit tool you mentioned."
Ye Xiaosheng said, pulling out a strange-looking spirit tool. The very front was a solid piece of rare metal that Wang Nan didn't recognize, with two dials fixed on it. One was somewhat similar to a compass, and the other had some markings.
"This is the preliminary spirit tool detector I made based on your idea. It can detect spirit power fluctuations within a one-kilometer radius. From these two dials, you can see the direction and approximate distance of the spirit power source."
Ye Xiaosheng then sighed, "The type of detection spirit tool you described is actually not difficult to make. The only challenging part is this rare metal that's sensitive to spirit power. It's just that no one would use a spirit tool for this purpose like you do."
"This is the most legitimate use, okay?" Wang Nan looked down. The pointer on it was constantly shaking, but the general direction pointed towards the Soul Guidance System's spirit tool testing area. This indicated that the spirit power fluctuations in the spirit tool testing area were the strongest.
On the Douluo Continent, aside from Spirit Masters of the mental force system who could use mental force detection, other Spirit Masters rarely could sense spirit power fluctuations in unknown areas in advance.
Wang Nan himself could slightly perceive his surroundings with his powerful mental force, but it wasn't as effective as a mental force system Spirit Master, and it consumed a lot of energy. If this type of detection spirit tool could be upgraded further, he wouldn't be completely blind in some unknown areas.
"This is the initial version. I'll find a way to upgrade it to increase its detection range and make the detection results more accurate."
"No rush, take your time. By the way, no one else knows about this, right?" Wang Nan asked.
"Who do you take me for?" Ye Xiaosheng's expression was a bit exaggerated. "Every Soul Master's exclusive spirit tool is top secret. Although you're not a Soul Master, I already treat you as one. I will absolutely not let your unique ideas get out."
Wang Nan and Ye Xiaosheng had known each other for a long time, so he naturally knew his character. Although he talked loosely, he was quite responsible, otherwise, Wang Nan wouldn't have entrusted him with making spirit tools.
In fact, Wang Nan had many other creative ideas. When Ye Xiaosheng's Soul Master Rank was higher, he planned to ask Ye Xiaosheng to help create a spirit tool detector that could be remotely controlled and capture images from a distance.
In Wang Nan's opinion, the Sun Moon Empire's spirit tool detectors still required a Spirit Master to personally sit inside and operate them, which was still a bit too backward.
