Qin immediately didn't believe it. After all, this was too much of a change in just a few hours. And, not to mention, this wasn't even a true realm. It was called the foundation realm because it was like the foundation of a building.
And, having such strength with just a foundation realm cultivation felt more like a dream. He couldn't wrap his head around this for a moment but soon, he decided to trust it. First, he trusted his own instinct. Second, he believed this cultivation technique could give him this strength considering that it didn't even have the cultivation realms.
So, he finally settled on that strength but he wasn't satisfied with this improvement. Rather to say, he knew he would need to face off against the stronger opponent, so he didn't want to go out with this much of the strength.
