Underestimation of Xuan Ming Elders?

[CC]

Another example of possible inconsistency is when You Tanzhi met palms with Ding Chunqiu, You was only able to force Ding back one step per palm. How can Ding receive it so well when even Xiao Feng found You Tanzhi's palms unbearable, and Xiao has 3+ times more internal energy than Ding?

Ermm, at this point, YTZ was severely hampered by his inner injury (he was spitting blood!). With massive internal injury, his power was still strong enough to push Ding back while recovering from his injury with each successive blow. That shows a big power difference.

Emmph what about this..

Everybody turned their eyes toward this person; he was none other than the Cult Leader of the Ming Cult, Zhang Wuji. His entrance was so sudden like he descended from the sky; everybody was shocked. Even masters like the Xuanming Elders did not expect anything like this that they were caught off guard.

Lu Zhangke heard the window burst; immediately he rushed to the front of Zhao Min’s body to protect her. He used all his strength to strike Zhang Wuji; but to his surprise his legs wobbled and he staggered back two steps. He was about to attack in anger when suddenly he felt an unbearable dry heat on his body, as if he was entering a hot furnace.

Zhang Wuji recognized He Biweng’s voice; anger welled up his chest. He roared, “You captured me when I was small and made my life nearly gone. Today you still have a face to speak to me? Take this!” With a loud grunt he sent out a palm toward He Biweng.


Lu Zhangke had just suffered a defeat; he knew He Biweng’s strength was not Zhang Wuji’s match. Rushing forward he shot a palm toward him. Zhang Wuji’s right palm was still moving toward He Biweng, his left palm moved underneath his right arm to block Lu Zhangke’s palm. Pure internal energy met pure internal energy, there was not the slightest margin of error. Three people, four palms. As soon as they met, they all staggered back.

While the Xuanming Elders were still stunned Zhang Wuji’s third palm strike arrived; as if by prior agreement each of them lifted a palm to block. Three people’s pure energy collided; the Xuanming Elders felt their opponent’s ‘yang’ [positive] energy surge in, it was difficult to block. Zhang Wuji’s palm technique was like the wind; he recalled his many years of sufferings when he was little and was struck by He Biweng’s Xuanming Divine Palm. For that reason his palm strike was a little bit lenient toward Lu Zhangke, he did not give any leeway to He Biweng.

Twenty or so palms later He Biweng’s greenish face had turned completely red. Seeing the opponent’s palm strike, he raised his left palm trying to fend it off, while his right palm is slanting down heavily. ‘Slap! Slap!’ He Biweng’s palm fiercely hit Lu Zhangke’s shoulder. In the end he still failed to fend off Zhang Wuji’s palm, which hit him squarely on his chest. Luckily Zhang Wuji had never had any intention to take his life; thus he only used 30% of his strength. With a ‘wah’ noise He Biweng spurted a mouthful of blood. His face from red turned to purple, his body swayed; if Zhang Wuji took advantage of this situation and launched another palm strike, his life would be gone right there and then. Lu Zhangke’s shoulder was also so painful that his face greatly changed and his lips bleed from his own biting.

If fight palm to palm 1 on 1 The Xuanming Elders only 30-40% of Wuji "strenght" but their "combined force" nearly as strong as Wuji or perhaps Wuji still held back at that time..
