For Yang Fan, Liu Qiankun is already a very important person in his life. Of course, Yang Fan didn't want Liu Qiankun to be in any danger.

The "Yang's Twelve Needles" that Yang Fan got is indeed extremely effective. But I don't know which ancestor of the Yang family who lacks heart and eyes, and recorded the "Yang's Twelve Needles". Can't you have a snack?

Each set of acupuncture, not to mention any effect, what sequelae. Even the acupuncture points of the needle are not recorded.

Yang Fan has to follow the distance ratio of several acupuncture points on the acupuncture point map, and then follow the order of the ground branch of Zi Chou Yinmao, and then compare the correspondence between the ground branch and the human body parts, and after careful comparison, he can confirm the acupuncture points.

And only confirming the acupuncture points is only the first step. The effect of the later acupuncture, and even the sequelae, are not recorded at all in "Yang's Twelve Needles".

So Yang Fan can only rely on observation.

Before, the first object of the Ziying Needle was Liu Qiankun. It has been a long time since Liu Qiankun was first cast with the Shadow Needle.

Judging from such a long period of observation, there should indeed be no serious sequelae here. That is, according to the person's physical fitness, he is weak for a period of time. But after this period of weakness in the past, it didn't make any difference.

Liu Qiankun was the first person to be cast with the effect of the Shadow Needle, but Yang Fan was the first person to be cast with the Shadow Needle three times. But judging from the shorter and shorter period of weakness in the back, Yang Fan can almost confirm the sequelae of the Ziying Needle, and there is really no need to worry too much.

However, the situation of the Lying Cow Needle is not the same as that of the Shadow Needle.

First of all, the difficulty of applying the needle is directly two heights higher than that of the shadow needle.

Secondly, the effect of the Lying Cow Needle is really too strong.

The effect of the shadow needle is indeed very strong. But in the end, some high-end stimulants can actually achieve similar effects to Ziying needles.

And the sequelae of these high-end stimulants are actually much stronger than the sequelae of the shadow needle.

The effect of the shadow needle is far away, and Yang Fan can still understand it. At that time, after using the shadow needle on Xiao Jieyu in desperation, Yang Fan paid close attention to Xiao Jieyu's follow-up situation.

To put it simply, the Shadow Needle can make people burst with more strength and speed. It is still related to adrenaline, and Yang Fan has determined that the secretion of adrenaline after the Ziying needle has indeed reached a peak quickly. The secretion of adrenaline decreases until it arrives between sustained spikes.

Moreover, the whole process of the shadow needle, the change of the human body shape, is actually a continuous process. In other words, Yang Fan can actually see Xiao Jieyu losing weight step by step from her original perfect figure.

An outburst of adrenaline, coupled with the consumption of nutrients in the body. In exchange for this, the target affected by the shadow needle was a result of a short-term explosion of combat effectiveness.

In the final analysis, these are all within the scope of science and can be explained.

So Yang Fan doesn't have too many worries here.

But the situation is different.

The bullet pierced through, and in less than half a minute, the wound had completely healed.

What the heck!

Yang Fan has always boasted of his extraordinary medical skills, but the effect of the Lying Niu Needle is really beyond the scope of common sense.

The frantic healing of wounds is one thing, and secondly, even the outbreak of sequelae is very tangled.

Before, Peng Yang and Liu Qiankun had not changed at all in the previous second, but when the time that the Lying Niu Needle could last was up, it was a situation where their body size was rapidly reduced.

Liu Qiankun is only a little thinner, but Peng Yang is directly skinny here.

The reason Yang Fan understands that the three energy substances of the human body are rapidly consumed, so it will cause such a result.

But what about the process?

Consuming energy and substances, Yang Fan understands. But how did your body hold up during the previous period, and how did you suddenly change in the last few seconds?

Yang Fan did not study any modern medicine, but received a traditional Chinese medicine education. It is a modern course, and it is a little bit of research on biology and chemistry and biochemistry.

But at the end of the day, it's really too easy for people to embrace modern ideas. As long as the Internet is not completely abandoned, all aspects of literacy can be quickly improved.

If you want to say how deeply Yang Fan suddenly has a deep understanding of the discipline of physics, it is not enough. But to put it simply, Yang Fan can almost identify which situations have violated scientific principles.

Now, the effect of the Lying Cow Needle has exceeded the scope that normal science can explain.

The Shadow Needle is only a stimulant-level effect, so the sequelae are very easy and nothing incomprehensible.

But you, the effect of the Lying Cow Needle is on the same level as the genetic mutation. Yang Fan is really worried about the sequelae of such a method.

For the killer at that time, Yang Fan tried such a technique, and he didn't have any burden in his heart. In the final analysis, this Peng Yang, as the killer of Poison Wind Valley, may not have done many bad things before. Who knows how many people he has assassinated at the behest of Poisonwind Valley?

And even if this is just speculation, there is no basis. To put it simply, Peng Yang is here to deal with Yang Fan, and Yang Fan has nothing to worry about.

In addition, Yang Fan was indeed a little curious about the effect of the Lying Cow Needle, so he used the Sleeping Cow Needle on Peng Yang. But if Liu Qiankun was here, there was really no other way at that time. Yang Fan explained that he didn't know the specific sequelae of the cow needle, but Liu Qiankun still insisted on giving it a try.

Under such circumstances, Yang Fan used the Lying Niu Needle on Liu Qiankun.

The effect of the Lying Cow Needle is too strong, even according to the conservation of energy theorem, Yang Fan is a little suspicious that the sequelae of the Lying Cow Needle may not be so simple.

If it weren't for the fact that the situation was really urgent at that time, Yang Fan might not want to use such a technique on his friends a few years later.

But since the Crouching Cow Needle has been used on Liu Qiankun, regret is useless.

What Yang Fan can do is to closely observe Peng Yang's situation here. If Peng Yang doesn't have any serious sequelae here, Liu Qiankun will still let him live freely. Liu Qiankun finally walked with Xu Lili, and Yang Fan didn't want to affect the quality of life of the two.

But if there is something wrong with Peng Yang here, if Yang Fan pays close attention, he will be able to find the problem as soon as possible. The first is to try to treat Peng Yang, even if the treatment of Peng Yang fails. Here in Liu Qiankun, Yang Fan has also accumulated more experience.
