The Central Continent Immortal Treasury.
The clang of hammering iron rang out in waves.
Throughout the valley, the sounds of hammering rose and fell.
Xu Qingxiao quietly watched it all.
At that moment, tens of thousands of fiend beasts were hammering immortal gold in the valley.
Some of the fiend beasts were also fighting one another, transforming toward the first rank.
After his earlier simple experiments, Xu Qingxiao understood that the Three Demon Mark could control these fiend beasts perfectly.
Whatever he told them to do, they would do.
There would not be the slightest hesitation.
Thus, an extraordinarily bold idea occurred to Xu Qingxiao.
Take them outside.
However, when he told the Pill Deity Ancient Scripture about this idea, it met with vehement opposition.
"Young friend, I mean nothing else by this. These fiend beasts are certainly powerful, but they also pose an enormous danger."
"If you take them all outside, it will be fine as long as you can control them. But what if you lose control once they leave?"
"I am not raising an alarm merely to frighten you. One careless mistake, and these fiend beasts could unleash a great purge. Even the whole of Central Continent could not withstand them."
The Pill Deity Ancient Scripture did everything it could to dissuade Xu Qingxiao. It knew how much pressure he bore.
But no matter how much pressure he bore, it did not want him taking such a risk.
"I understand."
After some thought, Xu Qingxiao nodded. He knew what worried the Pill Deity Ancient Scripture.
These creatures were like ticking time bombs. Used well, they could indeed work wonders and help him sweep across the world.
But if he mishandled them, or someone else also controlled the Three Demon Mark, he would be the one to suffer.
