Long ago, Jiang Chen had a doubt about the Immortal Slaying Sword Array. That is, the power of the Immortal Slaying Sword Array had a huge disparity.
When Demon Ancestor Luo Hou laid out the Immortal Slaying Sword Array in the past, four unparalleled figures led by Hongjun Daizu, holding the four Innate Treasures, went to break the formation. Although the formation was broken, two of the four great experts fell.
Despite being outnumbered four to one, Demon Ancestor Luo Hou managed to counter-kill two before being defeated by the Daizu. Thus, the formidable reputation of the Immortal Slaying Sword Array was established.
However, when Leader Tongtian also set up the Immortal Slaying Sword Array, it was easily broken by the four Saints.
The contradiction was glaringly obvious.
