"Your Highness, this old man has already studied your martial soul and soul ring configuration in detail."
"The soul rings of your third martial soul began at ten thousand years. According to this old man's deductions, this fourth soul ring should at least be over thirty thousand years, and ideally be kept within sixty thousand years. I wonder, Your Highness, do you have any soul beast in mind?"
As Thousand Machines Douluo spoke, he and Xu Tianyao moved through the dense forest.
Each of them held a palm-sized, notebook-like precision Soul Detection Instrument.
This was the latest detection Soul Tool developed by Mingde Hall. It could sense the surrounding Soul Power fluctuations and calculate a soul beast's approximate age, attribute, and location, greatly improving the efficiency of searching for a target soul beast.
Xu Tianyao nodded slightly. "My requirements are about the same as before."
"For the fourth soul ring, the age would ideally be between thirty thousand and sixty thousand years. It should primarily be fire attribute, and the stronger its bloodline, the better. As for exactly what kind of soul beast to choose, that can only come down to luck."
The Star Dou Forest was vast and boundless, with countless varieties of soul beasts.
But those that truly met Xu Tianyao's requirements were few and far between.
After all, his standards were too high. Not only did the age have to be suitable, it also had to possess top-tier fire-attribute talent and a powerful bloodline. Neither could be lacking.
A soul beast like that, even looking across the entire Star Dou Forest, was absolutely not something one could find anywhere.
Therefore, searching for several days, or even ten days to half a month, was perfectly normal.
Sure enough, after the first few days, they had found almost nothing.
