624 Speed

There were simply too many things for Lin Mu to do and he felt a bit overwhelmed. But eventually, he decided that since he had started with the formation creation first, he would stick with them. All the other occupations needed formations in some way or the other anyway and thus it would be helpful to him later.

~shua~shua~shua~

Little Shrubby's speed kept on increasing, and Lin Mu realized they were now faster than ever before. If it were not for his enhanced vision due to a higher cultivation, he would not have even been able to see things going by, as it would have all just been a blur.

"And the speed is still increasing…" Lin Mu muttered.

With every little step, Little Shrubby accelerated even more. Looking at the area, Lin Mu was sure they had already left the territory of the Ripple mist sect by now. Even though Little Shrubby had only been running for about five minutes now, they had quite likely went past at least a hundred kilometers.

Lin Mu looked back and could not see any signs of the Dao Shell realm cultivator at all.

"Seems like we left him far behind," Lin Mu said.

"With the speed you two are going, it would have been a joke if he was able to catch up." Xukong said. "Do you even know the speed at which you are traveling?" he asked.

"No… I can't really estimate it…" Lin Mu said.

"You two are traveling at nearly the same speed as sound." Xukong replied.

"The speed of sound?" Lin Mu repeated.

"If you go any faster your voice would be left behind if you talk." Xukong explained shortly. "Try it, try speaking."

"Ok-ay..?! wh-at?" Lin Mu spoke in a shocked tone.

To him, it felt like his voice was lagging behind him. And then it happened.

~BOOM!!!~

Lin Mu felt a shock wave emitting from around them as Little Shrubby's speed increased once more.

"Now you're moving faster than sound. That was a sonic boom. It happens when you break the sound barrier." Xukong explained.

Lin Mu and Xukong were talking using their connection and thus didn't actually need to speak verbally. All they needed to do was thinking and their thoughts would be transmitted to each other. Though Xukong had said to Lin Mu that it wasn't exactly that, as that thing would be called telepathy instead.

What actually happened was that both Lin Mu and Xukong's thoughts came to a common place that was made from a fragment of both their minds. In this 'shared space' their thoughts would appear and interact.

This was also where Xukong would be able to 'see' Lin Mu's memories when he shared it with him. Usually Lin Mu directed all his current memories to this place unfiltered because of which Xukong was able to see and experience the real world without causing problems.

But Lin Mu could also simply talk, and Xukong would be able to hear him. But now it was obvious that speaking was of now help as his voice would be transmitted but would be left behind. The only sound that Lin Mu heard while speaking was his own voice in his head that echoed in his skull.

But even then, he could clearly hear the difference between the sound that echoed in his head and the sound he heard externally. This was Lin Mu's second time experiencing this technically, but the first time he was not conscious.

The first time this happened was when Little Shrubby used the Seven Beasts Burst for the very first time. But now Little Shrubby could achieve the same speed without needing to use that innate skill.

"How fast would he be once the Seven Beasts Burst is used now?" Lin Mu couldn't help but wonder.

Lin Mu turned back to see if there was anyone following them and did not see the Dao Shell realm cultivator anymore. It was obvious that they had left him in the dust. Though, when he looked to the upper side, he saw none other than Jing Luo.

The man's long hair was blowing back due to the wind and every step he would soar forward. The boots that he was wearing allowed him to step onto the air and created a strong jet of wind from them.

As for the belt that he was wearing, it continued to emit spirit Qi fluctuation and had several points on it that glowed. Though when Lin Mu looked at it, he found that after a few seconds, one of the glowing points stopped glowing.

And after another minute, one more point stopped glowing.

"What is that…?" Lin Mu muttered to himself as he focused on the belt.

Still, it was hard to do so when they were moving at a great speed and thus he decided to improve it a bit. He chanted the calming heart sutra and felt everything slowing down a bit. He opened his eyes and gazed at the belt again, and finally understood what those glowing points were.

"High Grade spirit stones?" Lin Mu recognized.

Each of the glowing point was a high grade spirit stone, that had been embedded into a socket around which a small formation was inscribed. The glow that he saw was actually coming from the formation itself rather than the high grade spirit stone.

And the reason why it stopped glowing was that the high grade spirit stone was depleted of its spirit Qi. Once that happened, the high grade spirit stone would crumble to dust and scatter, deactivating the formation.

Lin Mu couldn't really tell how this all functioned just from seeing and decided to ask Jing Luo once they stopped.

"How long can you run at this speed for Little Shrubby?" Lin Mu questioned the beast.

"I don't know. I feel like I can just keep on running." Little Shrubby answered.

"Hmm… keep on running till Jing Luo can run. Once his speed is reduced and he needs to rest, we shall stop as well." Lin Mu replied.

"Okay~" Little Shrubby said and kept on running at the same speed.
