Since Lanny, probably one of our finest XAJH resident experts, has arrived at Spcnet, and knowing the opinions of several other XAJH fans, I thought I'd compiled a list of all the 'special' feats which were performed by people in XAJH, in an effort to create an aggregate comparative list showing the XAJH skill level vis a vis other works.
1) Sealing accupoints through the air:
A fourth tier fighter, one of the Peach Blossom freaks was able to seal the accupoint of Lu Dayou through the air, without physical contact. From Lanny's translation, chapter 10, "He didn’t even bother turning around and simply pointed backward with his finger. In a whistling sound, he had sealed Lu Dayou’s Mute Point with a beam of energy."
2) Striking with lethal force with LDA.
It was stated in TLBB that only the greatest masters were able to strike from far distances: from CC's translation, "What was known amongst martial artists as 'Striking Oxen over Mountains' referred to various Masters who could use invisible palms and fists to strike over thin air, but even the greatest of fighters could not transmit their inner force much more then 20 feet away."
Yet, in Chapter 18, yet another 4th tier fighter, Yue Hou, was able to strike LHC from 'an extreme distance'. From Lanny's translation, "At the time Yue Hou was at a good distance from him. When Yue struck out with his two palms remotely, he had no way of warding the attack off using his long sword [.....] Succeeded with his remote palm strikes, You Hou figured that his opponent would at least drop down with severe injuries if not drop dead."
The actual hanzi used were "相距甚远", at an extreme distance, so if anything, Lanny played down on this. At least, we can assume 10 or so feet.
3) Really strong legs:
A third tier fighter, Xiang Wentian was able to, without effort, boot a heavy horse weighing 500 pounds into a ravine. If even his kicks manage to have that much force in them, how much more would his palms? From Lanny's translation, Chapter 18, "Linghu Chong gasped with astonishment. The horse, a large beast, weighed at least five hundred pounds. He almost couldn’t believe his eyes when he watched Xiang Wentian booting it into the ravine with such a casual kick."
4) Even stronger legs:
Later on, the infamous scene at the Plum Manor, where Xiang Wentian, a third tier fighter, without moving, was able to press a DEEP imprint of his feet down on the stone simply by shifting his internal energy towards it, showing perfect control of inner force as he didn't damage or crumble any of the bricks surrounding it. This has been argued to death, and I'm not going to go into it in more depth, but the fact remains that a 3rd tier fighter did something similar, at least, to what we have only seen first tier fighters do.
5) Strong fingers too!
Fang Zhen and Chong Xu of Shaolin and Wudang were able to easily write on wood with their fingers at great fight at Shaolin, in Chapter 27. This was something that Qiu Chuji said that would even probably give Yideng, using Yi Yangzhi, a hard time. It's been suggested that he wasn't in an accurate position to judge how easily or how difficult it actually would've been for Yideng, but the fact remains, it's clear that doing something like that was far beyond his own level, and by saying it would be "hard for Yideng with the best finger skill in the world", he directly implies that it probably would've been impossible for his own master to do as well. Again, this isn't necessarily definitive proof, but it's definitely something to ponder.
6) Even stronger fingers as well!
Ren Woxing was able to write words on STEEL; in the cage under the Western Lake, he managed to carve out the instructions for practicing his Xixing Dafa onto the steel plate he slept on. "There were words marked on his skin everywhere he felt. Each character was about the size of a copper coin. The strokes were very deep, but the handwriting was hasty and careless."
It's been argued that Ren Woxing probably wrote the words with his own chains after he sharpened them, but I find that improbable. For one, the strokes were 'very deep'; the only possible way he could've written deep with blunt chains would've been to sharpen them to an extreme degree. These weren't huge, fat words; each word was about the size of a copper coin. If Ren Woxing was able to sharpen his chains that much (and they were made out of a special material), one would imagine he'd be able to snap them as well, for one.
For another, the handwriting was described as being 'hasty and careless'. If he had sharpened his chains for many months or years, would he have written that hastily and carelessly? It's strongly implied by the way JY describes the carvings that RWX wrote it down on a sudden whim, which doesn't jive well with all the time spent sharpening/wearing down the chain (if that was even possible) he would've had to spend.
7) Sword Qi
Mr. Paint, at best a third tier (probably fourth) fighter, was able to use sword qi against LHC in Chapter 19. "Before he even recomposed to a firm stance, he had drew three circles in front of him with his long sword, which magically changed into three circles of light. The three circles of light looked as though they’d actually materialized. After freezing in the air for a moment, they began moving toward Linghu Chong gradually. At the first look, these sword energy turned circles of light did not appear as swift or fierce as the “Straight Line Lightning Sword,” but the energy released easily filled the entire room and everyone felt the chilling force coming from them."
That's sword qi, straight from Jinyong's own writing, in a 3rd or 4th tier fighter. Where's the only other place we've actually SEEN sword qi?
That's right, TLBB's Liumai Shenjian.
8) Music and Internal Energy
Huang Zhong, a third tier fighter, in Chapter 20, was able to infuse the music of his zither with his own internal energy, to control that of his opponent's. "He had actually infused superior inner strength into the zither sounds in order to disrupt his opponent’s concentration. Once the opponent’s internal strength resonated with the zither sounds, then he would be controlled by the zither sounds involuntarily. When the zither music slowed down, the opponent’s movement would also slow down; when the zither music hurried, the opponent’s movement would also hurry."
Sound familiar? It should. The other time you've probably encountered something similar was with Huang Yaoshi, in dealing with Li Mochou (and much earlier, with Zhou Botong).
I'm sure there's many more examples that can be given by the likes of Lanny and bliss, who's knowledge of XAJH probably far exceeds mine. Feel free to add and discuss them here
