"This poison's toxicity has actually increased!" Master Gongsun exclaimed, his face filled with shock as he examined the poison in Su Keqing.
Upon hearing this, Murong Xue also stated dazedly, "Not only that, but the toxicity is still increasing. It will soon surpass the level of potent poison!"
Everyone present was greatly astonished by this statement.
Generally, poisons maintain a stable toxicity. After a person is poisoned, the toxins are affected by the body's immunity and might weaken, but they would never strengthen!
Yet, the poison in Su Keqing was growing stronger and continuing to do so, which was unprecedented.
Hearing this, Ye Feng continued, "Keep observing."
The two continued to observe silently. Soon, the poison's strength surpassed the potent poison level, nearing the super potent poison level, which frightened them both.
The thought that they had considered using poison to counter poison to detoxify Su Keqing instantly turned their faces ashen.
If Ye Feng hadn't appeared to stop them, either of them using the poison-to-counter-poison method would have undoubtedly harmed Su Keqing.
Seeing this, Ye Feng raised his hand and waved. The silver needles on Su Keqing's arm instantly flew back.
This once again shocked everyone present.
After Ye Feng retrieved the silver needles, the toxicity of the poison in Su Keqing slowly weakened, returning to its original state.
At this moment, Ye Feng continued to ask, "Do you now feel that your previous methods were appropriate?"
Master Gongsun shook his head. "No, they were not appropriate! Thank you, Master, for stopping me, or I would have harmed Miss Su!"
Murong Xue also hurriedly asked, "Why is this poison so peculiar?"
Hearing their words, Ye Feng smiled and explained, "This is a very ancient poison. On the surface, its toxicity is not very strong, only equivalent to a standard potent poison! However, once this poison is stimulated by other toxins, its toxicity will immediately strengthen!"
"One could say that this poison superficially meets the conditions for using poison to counter poison, and it doesn't seem very difficult to resolve. But in reality, once stimulated by other toxins, its toxicity will grow to the level of super potent poison, even far surpassing many super potent poisons!"
Hearing Ye Feng's explanation, the two suddenly understood.
In fact, Ye Feng had only recently learned about this poison. If he hadn't glanced at the ranking of potent poisons while researching Xiao Hei's toxins, he probably would have thought it was just an ordinary poison.
In reality, after being stimulated, this poison's maximum toxicity surpasses many super potent poisons, ranking ninth on the list of potent poisons.
At this moment, Murong Xue asked again, "Then how can this poison be resolved?"
Hearing this, Ye Feng replied, "There are two ways to resolve this poison. The first is to find the corresponding medicinal substances, but this is very troublesome and requires extremely precious medicinal materials. The other method is what you were attempting, using poison to counter poison!"
Upon hearing the first method, the two immediately nodded, finding it very reasonable.
After all, for any poison, finding the corresponding antidote would naturally resolve it.
However, upon hearing the second method, they were once again confused.
They asked, "Didn't you say its toxicity would continuously increase, and the poison-to-counter-poison method couldn't be used?"
Master Gongsun also showed a look of confusion, staring at Ye Feng with a puzzled expression.
Ye Feng then explained, "It's not that the poison-to-counter-poison method cannot be used, but rather that the poison you used was not strong enough, and therefore could not be used to counter this poison!"
This confused Master Gongsun, who asked, "Master, the poison I used before was only at the upper-middle level of potent poisons, indeed no match for this one! But Miss Murong's Five-Colored Poisonous Centipede is a super potent poison, is that also not effective?"
Ye Feng nodded. "Of course not! Although the Five-Colored Poisonous Centipede's toxicity has reached the level of super potent poison, it is still inferior to this poison!"
The toxicity of the Five-Colored Poisonous Centipede ranks in the nineties on the "Poisonous Ranking" in "Medicine Immortal," while this poison ranks ninth. To use it to counter this poison, it is still far from sufficient.
Only a few poisons ranked higher than it on the list could surpass its toxicity. Therefore, to use the poison-to-counter-poison method to resolve this poison, one must use one of the poisons ranked higher.
Hearing this, the two asked, "Then what kind of poison should be used?"
Hearing this, Ye Feng smiled and said, "It's right before your eyes, yet far away. Guess!"
This statement left the two confused. However, the next second, they saw the small black snake in Ye Feng's hand and spoke in unison, "The poison of the Myriad Poisonous Snake?"
Hearing this, Ye Feng smiled. "That's right! Alright, I've explained enough to you. It's time to detoxify Keqing!"
Saying this, Ye Feng signaled for everyone to make space, then prepared to detoxify Su Keqing.
"First, when using the poison-to-counter-poison method for detoxification, it is crucial to protect the patient's vital areas, such as the heart, brain, liver, and so on!"
"Because when the two toxins confront each other during this method, they might harm the patient's heart, brain, and internal organs! In mild cases, it can lead to becoming an imbecile or a vegetative state, and in severe cases, immediate death..."
As Ye Feng explained to the people present, he opened three other unused sets of silver needles.
The next second, he waved his hand again, and those silver needles flew out once more.
This time, it made everyone's eyes widen even further, because with a wave of Ye Feng's hand, all three sets of silver needles flew out.
The silver needles seemed to have eyes, accurately piercing the areas around Su Keqing's heart, near her forehead, and even her limbs.
More importantly, when Ye Feng had previously inserted needles into Su Keqing's arm, he had rolled up her sleeve.
Now, with Su Keqing fully clothed, Ye Feng, with a wave of his hand, accurately inserted the silver needles into the various acupoints through her clothing.
This miraculous scene caused everyone present to stare with wide eyes.
Among them, Master Gongsun's mouth hung open in shock, his face filled with disbelief.
Ye Feng had taught him a little about acupuncture, and he believed he had mastered eighty percent of it.
Now, seeing Ye Feng's technique, he knew he had only learned a superficial aspect.
As for Su Keqing, she stared at Ye Feng's acupuncture technique with wide eyes and exclaimed excitedly, "Master Gongsun, is this, is this the genuine Nine Palaces Needle Technique?"
Master Gongsun nodded. "That's right, this is the genuine Nine Palaces Needle Technique. I thought I had learned eighty percent of it, but now I see I've only learned a mere fraction from Master!"
Putting aside other things, just Ye Feng's technique alone, Master Gongsun estimated he wouldn't be able to learn it in eight to ten years.
After all, to accurately insert silver needles into acupoints with just a wave of his hand, and even through clothing, required such profound experience and skill.
Master Gongsun's admiration grew with every passing moment.
Meanwhile, Murong Xue, standing beside them, kept her gaze fixed on Ye Feng, her expression shifting between excitement and daze as she murmured, "Wonderful, it's the genuine Nine Palaces Needle Technique! It's the genuine Nine Palaces Needle Technique..."
After Ye Feng finished inserting the silver needles, he checked Su Keqing's condition again. Then, his subsequent actions made everyone's eyes widen even further...
