Cang Yongning was indeed an opponent worthy of respect.
This was Cang Yongning's most difficult battle. So how was it also not Ye Yuan's most difficult battle?
Although this guy was haughty, one had to admit, he was absolutely an alchemy path genius!
In alchemy, Ye Yuan had never been unduly humble, he knew that he himself was a peerless genius.
But Cang Yongning was no less inferior to him from any angle.
This guy was remarkable!
But that was also more worthy of victory.
This battle, the harvest that Ye Yuan obtained was inestimable!
Three months of fierce fighting had stimulated all the potential in his body.
If he still could not break through like this, then Ye Yuan would also be too much of a failure.
In reality, what was hard was not refining true grade.
The truly difficult thing was refining true grade under the suppression of your opponent!
That needed your strength to truly overwhelm your opponent!
