As for why he could not detect Mu Qing's aura, Emperor Mo Luo did not pay it much mind.
He merely assumed that Mu Qing had cultivated some special divine ability that allowed him to completely conceal his aura.
Emperor Mo Luo had in fact been pursued by the experts of Heartless Hall all this time. Though he was not worth the Heavenly Emperor personally making a move, the Heavenly Emperor's avatar—the one who served as the master of Heartless Hall and was known as the Heavenly Dao—would occasionally hunt him down.
However, Emperor Mo Luo truly was no ordinary figure. During this period, he had evaded pursuit while cultivating with the supreme treasure he had obtained from the Eternal Emperor, successfully reaching the half-Supreme realm!
He had even successfully condensed both a Supreme Dao and a supreme artifact. Like Mu Qing, his next step was to undergo a great self-collapse and break through to the Supreme realm!
Emperor Mo Luo had been hiding all this time and knew absolutely nothing of the outside world. He normally did not even have the leisure to visit those peak races and gather intelligence, so his understanding of Mu Qing remained stuck in the past.
He believed that no matter how talented Mu Qing was, at most he could have cultivated to the peak of the extreme rank.
How could he possibly be a match for him?
Then, looking at that top-grade divine stone mine vein, Emperor Mo Luo's heart burned with desire.
If he obtained it, his chances of successfully breaking through to the Supreme realm would rise greatly!
"Since that's the case, I'll kill you first, then seize the top-grade divine stone mine vein!"
Emperor Mo Luo roared. Blazing fire suddenly ignited around his body, forming gaseous flames that burned fiercely.
