To a Dou Huang expert, the Tianxin Mountain Range was not particularly dangerous. Some Fifth-Tier Demonic Beasts sensed the presence of humans, but with a Dou Huang expert like Xiao Shuang present, none of them launched an attack.
Of course, Xiao Shuang's aura deterrence only affected those Fifth-Tier Demonic Beasts. Lower-tier demonic beasts could not sense the aura he had deliberately released, while Sixth-Tier Demonic Beasts would not feel intimidated by it.
That did not mean Sixth-Tier Demonic Beasts feared Xiao Shuang. They simply did not want trouble. If they truly fought, each of those Sixth-Tier Demonic Beasts possessed its own pride.
Because of this, the demonic beasts Xiao Shuang's group encountered blocking their path were only Third-Tier and Fourth-Tier Demonic Beasts, which were not difficult for Ning Xiyao and Ning Zhiyan to handle.
Working together, the two killed three Fourth-Tier Demonic Beasts and nine Third-Tier Demonic Beasts along the way. These demonic beasts all contained magic cores, and together with the herbs guarded by some of them, their gains were quite plentiful.
Suddenly, Ning Xiyao's body stiffened. An inexplicable suction force abruptly emerged from within her body, and the energy of heaven and earth around her began rushing in rapidly.
After sensing her own condition, Ning Xiyao turned to Xiao Shuang and softly asked, "Teacher?"
"Breaking through?" Xiao Shuang's expression remained calm. After surveying the surroundings, he said, "Enter a cultivation state. Opportunities like this are hard to come by, so don't waste it."
"Your teacher will stand guard here. Break through without worry."
After speaking, Xiao Shuang stepped back two paces and leaned against a large tree.
"Yes!" Ning Xiyao did not hesitate in the slightest. She immediately sat cross-legged on the ground and circulated her cultivation technique, accelerating her absorption of the energy of heaven and earth.
