Lin Mu knew that if they went any fast, they would leave behind Jing Luo as well. And it was better for them to run alongside for now, just in case anything happened that they had not expected. They continued for about twelve more minutes before finally stopping.
An audible crack was heard as Jing Luo slowed down and stopped. Lin Mu and Little Shrubby stopped along with him and looked at him.
"Ran out of power?" Lin Mu questioned.
"Indeed..." Jing Luo said as he took a look at the belt he was wearing.
All of the high grade spirit stones that were embedded in them were broken and now there were only empty sockets left in their stead.
"So this was why you were assured you would be able to keep up with Little Shrubby?" Lin Mu questioned.
Little Shrubby was also looking at Jing Luo in intrigue and felt a bit threatened. He was the fastest being right now, and he didn’t want someone else to be faster than him, especially not Jing Luo.
"Yes, these are the spirit tools I made in case we needed to escape and they did end up coming in handy." Jing Luo replied as he took off the belt from his waist.
"So what are these exactly?" Lin Mu questioned.
"Hmm... you can think of the belt as a disposable high grade spirit tool while the boots are just normal high grade spirit tools." Jing Luo answered.
When Lin Mu heard the word disposable High grade spirit tool, he didn’t know what to think of it. Perhaps in this world, only Jing Luo and a few handful of people would say the words Disposable and High grade spirit tool in the same sentence.
"I see. So the belt functions as a battery?" Lin Mu asked, remembering some of the concepts from the jade slip Jing Luo had given him.
"Yes. But a very high powered one. I had to use high grade spirit stones to make this work for the boots. While I can make a lower quality version of this as well, I finally found out the upper limit of what the belt can handle as of now." Jing Luo replied.
Lin Mu felt quite a bit intrigued by this and wanted to know more. His curiosity had always been high and every time he got to learn something new, he would benefit from it. He definitely wanted to know how these two worked.
"How do they work?" Lin Mu questioned.
"I’ll tell you, but I think we should find a place to rest first. I don’t know about you, but using these two spirit tools put a bit of a strain on my body. I don’t know how you two can keep up with a speed like that." Jing Luo said as he massaged his neck.
"Oh! Okay, let’s find a place to rest for a bit." Lin Mu said and the two men looked around with their spirit sense.
It didn’t take them long to find a dense thicket of trees some distance from them. The crown of the trees completely covered the sky while the bushes and smaller trees around, blocked the view of what was hidden within it.
Of course, a location was quite unusual and Little Shrubby told them that this was the nest of a beast. Currently, the beast was not there thus they could go there and would not need to bother with it... hopefully.
And if the beast came back before they were done resting, it would be unfortunate... for the beast.
Jing Luo didn’t rest right away though. He first threw out four flags, that implanted themselves into the four cardinal directions around the thicket. Once that was done, a thin barrier appeared around it and a few runes floated around.
Jing Luo scanned it over with his spirit sense and they all faded away into nothingness as if they never existed. The flags also went deeper into the ground, completely disappearing from their view.
"This should be a bit safer," Jing Luo said as he sat down with his back to a tree.
Lin Mu could see the visible fatigue in the man and knew that he was truly affected by the spirit tools.
"Why are you so tired from that?" Lin Mu asked curiously. "Being at the Adolescent Soul Stage of the Nascent Soul realm, you should be stronger than that."
Jing Luo had a bitter expression on his face after hearing Lin Mu’s question.
"Not everyone has a body like you and cultivates all the way to the thirteenth stage of the Body tempering realm. I don’t even know how the hell you accomplished that." Jing Luo said, feeling a bit insulted.
But then he saw the look on Lin Mu’s face that showed pure curiosity and understood that Lin Mu didn’t really mean to insult him like that.
’What kind of a master does this guy even have? How did he train him ?’ Jing Luo wondered.
"The speed at which we ran... you must have seen that we outrun the Dao Shell realm cultivator, as well. From that, you should be able to tell, how much power it would require to do the same for a normal cultivator." Jing Luo hinted.
Lin Mu went over it in his mind and realized that it was truly far more than should have been possible for any normal cultivator, even if they were at the Dao Shell realm.
"Ah, no wonder your body hurts." Lin Mu said in an understanding tone.
"Exactly. While the Wind strider boots are extremely fast, they need an equally strong spirit Qi supply. And while I can provide it with my body as well, the speed of infusion that it needs would not be enough. Thus I ended up adding the spirit Qi infusion belt to the combination." Jing Luo said and took a pause.
He took out a couple of alchemical pills from his spatial storage treasure and ate them.
