Through Tian Shu's account, Feng Qi gained a detailed understanding of why he had chosen to seal himself inside the underground prison.
Back then, Tian Shu had pursued Domain Creatures back to the human world while in an out-of-control state, yet he did not possess Mu Yao's ability to return to the Road to Heaven.
At that point, he was undoubtedly a ticking time bomb.
He could lose control at any moment, and while out of control, he had no way to restrain his own actions.
More importantly, the duration of those episodes was completely unknown.
They might last only a few hours, or several days. Nowhere was necessarily safe.
He might even charge into a human city while out of control.
For the major cities, which had only recently established their Cultivation Studies systems, that would have been a horrifying disaster.
Faced with this situation, Tian Shu, who had never managed to find Mu Yao, could only choose to seal himself away.
Only that could resolve the series of crises he might bring upon human civilization.
After learning the reason, Feng Qi could not help asking:
"Uncle Tian Shu, I understand why you chose to seal yourself, but can the metal used to make this prison withstand the power you unleash when you lose control? Did humanity already have the ability to produce this kind of special metal back then?"
As he spoke, Feng Qi turned his gaze toward the metal bars.
"The origins of this special metal are far from simple. It was a precious treasure I acquired while guarding Main Route 32. Not only can it absorb power, it also possesses sealing properties."
At that point, Tian Shu looked at Feng Qi and said:
"You can try touching it. Then you'll understand what I mean."
Without hesitation,
