The moment the Tool Soul Avatar appeared, its terrifying might swept across the entire field.
The Seven Kill Sword hurtling toward Tang San was instantly knocked away, spinning back to Sword Douluo's side to hover in midair.
Seeing Tang San suddenly unleash a Tool Soul Avatar, Yu Xiaogang stood frozen beside the battlefield, his heart shaken beyond measure.
He knew the Seven-in-One Fusion Skill he had developed would give the Shrek Seven Devils an enormous boost, but he had never imagined it would be this great.
According to his deductions, if the Shrek Seven Devils worked together to unleash the Seven-in-One Fusion Skill and concentrated all their soul power in Tang San, Tang San's strength would surpass the Soul Emperor level.
Now, that deduction seemed rather conservative.
Clearly, the Seven-in-One Fusion Skill could not only raise the Shrek Seven Devils' collective strength beyond the Soul Emperor level, but even bring it to the Soul Saint level.
In fact, according to Yu Xiaogang's original deductions, the Seven-in-One Fusion Skill would give the Shrek Seven Devils strength beyond the Soul Emperor level, but would not reach the terrifying heights of a Soul Saint.
On that point, he had been correct.
The reason it had reached the Soul Saint level in practice, allowing Tang San to use a Tool Soul Avatar without a seventh spirit ring,
was that Ning Rongrong had incorporated the Ring Fusion Secret Technique while releasing her soul power, raising the total amount of the seven members' fused soul power another one or two steps above its original foundation.
Only then had it become enough to support Tang San in unleashing the Tool Soul Avatar.
Of course, Yu Xiaogang knew none of this, but that did nothing to diminish his shock, excitement, and elation.
That was a Martial Soul Avatar!
