Lei Zhen saw that Yuan Shu was only concerned about rubbing his thighs and didn't care about his explanation at all, so he asked, "Did your leg hurt just now?"

Yuan Shu heard Lei Zhen's light voice, and immediately stopped the movement in his hand, "It doesn't hurt, it doesn't hurt at all!"

"It really doesn't hurt?" Lei Zhen pretended not to know if Yuan Shu was in pain, and deliberately asked Yuan Shu.

Yuan Shu hurriedly said, "It doesn't hurt!" He was afraid that Lei Zhen would not be able to get used to him rubbing his legs and deliberately find fault, so he stopped what he was doing and pretended not to hurt at all.

"It's strange, I work so hard, how can it not hurt?" Lei Zhen pretended to say to himself, "There must be something wrong, I'll try a little harder!"

Yuan Shu was frightened when he heard this, and hurriedly said, "It hurts, it hurts!

Lei Zhen said in a 'sudden realization' tone, "It turns out that there is no mistake, you still feel the pain!" and then he changed the subject, "What is pain, how do you feel the pain?"

Yuan Shu wants to cry without tears now, he is not afraid of the sky, and he is not afraid of the earth, he is afraid that people will give him the truth! Yuan Shu was completely restrained by Lei Zhen, and now he is very well-behaved and obedient! But the problem still arises, he doesn't know how to answer Lei Zhen's question at all!

What do you mean, 'What is pain, and how do I feel pain?' It's not what you tossed? Yuan Shu secretly cursed in his heart! But he didn't dare to say this big truth, so he could only hum and chirp, but he didn't say a word!

"I don't know what the pain is, a pain will kill someone!" Lei Zhen didn't seem to know Yuan Shu's embarrassment, "I didn't hit you, I didn't pinch you, why do you feel pain?"

Yuan Shu squeaked, he really didn't know what to say! Just when he rubbed the sore spot with a sad face, he suddenly found that he didn't seem to feel the pain anymore!

"Do you still feel pain?" asked Lei Zhen at the right time.

Yuan Shu touched the sore spot twice more and found that it really didn't hurt at all, "I don't feel any pain." ”

"Why don't you feel pain again?" Lei Zhen then asked.

Yuan Shu felt very embarrassed: What is this, can't you ask some simple questions? Before he could make up an answer, he heard Lei Zhen say, "Bear with it!"

Then Yuan Shu felt a burst of 'pain' ten times more than just now, and a hundredfold pain appeared everywhere in his body! That kind of pain was not the kind of pain that was fatal with a blow, but the kind of stinging pain like a needle prick!

Yuan Shu wanted to use his hands to soothe the pain points in various parts of his body. However, the stinging pain appeared all over the body, and it was irregular. Therefore, in an instant, Yuan Shu became a 'monkey' dancing with his hands and feet, jumping in place non-stop.

After a while, the pain on Yuan Shu's body disappeared instantly, and he also fell to the ground due to exhaustion!

"Is it fun?" asked Lei Zhen as he looked at Yuan Shu, who was lying on the ground exhausted.

"What the hell do you want to do?" Yuan Shu was furious!

"Tell me, what is pain?" Lei Zhen threw out the question again.

"I don't know!" Yuan Shu yelled.

"Feel it with your heart!" Lei Zhen ignored Yuan Shu's anger. Said lightly.

As Lei Zhen's words fell, the bursts of pinprick-like pain swept through Yuan Shu's body again.

Yuan Shu rolled around on the ground in pain, and cursed Lei Zhen at the same time, "I'll grass you go wild!"

Three minutes later, the pain on Yuan Shu's body disappeared again! At this time, Yuan Shu was like mud, sticking to the ground.

"Tell me, what is pain?" Lei Zhen threw the question again.

Hearing this question, a tear slipped from the corner of Yuan Shu's eyes, "What do you want to do?"

"I'm telling you, what the hell is a living being!" Lei Zhen said lightly, "Tell me, what is pain?"

In the past, Lei Zhen would always tell Yuan Shu the answer when he couldn't support it! However, this time, Lei Zhen was determined to let Yuan Shu experience it and find out the answer himself, so he was very vicious.

The pain struck again, but Yuan Shu was no longer able to struggle, just lying on the ground. The pain hit one after another, Yuan Shu gradually felt numb all over his body, and suddenly the pain disappeared again!

"Tell me, what is the pain?" asked Lei Zhen again.

At this time, Yuan Shu was no longer possessed by his body, he only felt that his whole body was fluttering, his mind was in chaos, and when he heard Lei Zhen's question, he said unconsciously, "I don't feel pain!"

"That's right!" Lei Zhen heard the answer he wanted to hear, and finally let Yuan Shu go!

At this moment, Yuan Shu suddenly felt a heaviness in his body, and then, he also regained his clarity, thinking of everything that had just happened, he hurriedly asked Lei Zhen, "What happened just now?"

"Nothing!" Lei Zhen said, "just to give you a taste of the out-of-body feeling!"

Yuan Shu was stunned, "What do you want to do?"

"There are some things that no one will believe when they say it!" Lei Zhen explained, "but when they experience it for themselves, they will be convinced!

Yuan Shu looked confused, "What do you mean?"

Lei Zhen began to explain, "In this world, there is no pain, and there are no seven emotions and six desires, there is only one thing, and that is the 'stress response'! To put it simply, it is stimulated by the outside world, and then react! This is the essence of living beings!"

Yuan Shu carefully experienced what Lei Zhen said, and found that everything in the world can be summed up in terms of 'stress reaction'! Just like two strangers, if one of them doesn't speak, then the two will never get acquainted one day. However, he couldn't see what this so-called 'stress response' could do, so he asked, "So what?"

"Do you feel pain in your soul state?" asked Lei Zhen.

"No!" Yuan Shu said affirmatively.

"Then do you think, when you feel pain, is it because your soul feels pain, or does your body feel pain?"

"It should be the physical body!" Yuan Shu thought for a moment, "After all, when the soul was out of the body, I didn't feel any pain in the body!"

"So, why does your body have a 'stress response'?" Lei Zhen's questions one after another.

When Yuan Shu heard this, he had completely collapsed, he really wanted to open Lei Zhen's skull to see what was in it, and why there were so many problems! Yuan Shu sighed in confusion, "I don't know!"

Just when Yuan Shu thought that Lei Zhen would teach him a lesson, he heard Lei Zhen ask him, "Do you remember the general outline of the Tao Sutra? Tai Chi gives birth to two yi, which is for yin and yang! What does it mean that two yi give birth to four images?"

As soon as Yuan Shu heard Lei Zhen's reminder, he hurriedly used his brain, "Yin and Yang are the opportunity for movement and stillness, and the four images are the changes of Yin and Yang!"

"Then do you understand why there is a 'stress reaction'?" Lei Zhen asked the original question again!

Yuan Shucai couldn't understand it, but he suddenly thought of a phenomenon - slapping!
