Lin Mu opened his eyes and let out a breath. He had been refining his spirit sense for the entire day and now it was nighttime. He extended his spirit sense and saw that it had now reached a maximum range of eight meters.
In this entire day, Lin Mu was able to increase its range by one whole meter. He also failed multiple times, which caused him to lose a certain amount of spirit qi. But he didn't falter and was able to replenish it rather fast.
Now that he had reached the late stage of the qi refining realm, Lin Mu's speed of replenishing his spirit qi had increased two-fold. Previously it would take him over four hours to replenish the entirety of his dantian. But now it only took him two hours to do the same.
