Back then, when Liu Zixuan was at the Early Stage of the Imperial Realm, he used the Seventh Transformation of the Nine Transformations of Qiankun to gravely injure Shi Kui, who was at the Middle Stage of the Imperial Realm.
The current Nine Dragon Qiankun Array is a combination of the Eighth Transformation of the Nine Transformations of Qiankun and the Nine Dragon Array, and is many times stronger than the Seventh Transformation of the Nine Transformations of Qiankun.
If he were to encounter Shi Kui at the Middle Stage of the Imperial Realm now, he could completely erase him with this array!
Therefore, trapping Liu Qianfeng, who is at the Half-Step Emperor Realm, is naturally very easy.
Of course, after all, it's not an easy task to obliterate a strong figure at the Half-Step Emperor Realm.
If Liu Zixuan reached the Peak of the Imperial Realm, maybe he could, but for now, he has to think of some other plan.
