As Xuan Hao arrived at the ascension platform for those trying to breakthrough to the Nascent Soul Realm together with Bai Ning, he didn't give him any chance to escape, as he directly sealed off the area. Kindly reminding this little disciple of his that he would be able to leave after he broke through to the Nascent Soul Realm.
Of course, as a reward for breaking through to the Nascent Soul Realm, he also promised him that he would teach him in the Dao of Blacksmithing after his breakthrough. Making sure to demonstrate a bit of the knowledge he had gained after comprehending the Dao of Blacksmithing to the Small Success Realm to encourage him.
And unsurprisingly, Bai Ning didn't waste much time after this, as he directly began the process of breaking through to the Nascent Soul Realm in a simple yet smooth manner. Easily passing through the cloud tribulation without any real problems before starting the process of consolidating his cultivation base.
