Even while just flying level, Sword Essence was still continuously scouring his Dao Vein.
This feeling of getting stronger just by idling, without any conscious effort, was truly captivating.
He flew like this for a tedious hour.
[Innate Sword Body Tempering Progress: +1.]
[Current Progress: 35/10000.]
A line of small text appearing in his vision stunned Han Feng for a moment.
Other than the Foundation Establishment Empowerment, this was the first time he'd ever received a notification about his Innate Sword Body progress increasing.
This notification made him realize he could improve his Innate Sword Body by practicing the Sword Control Technique while piloting the fighter jet.
However, the rate of improvement was painfully slow.
'Only one point per hour?'
And upgrading the Innate Sword Body to the Middle Level required ten thousand experience points.
In other words, he would have to fly the Hunting Falcon in the sky for ten thousand hours.
