Han Yi got dressed and nodded, if he was attentive, he could feel a cool thin line on his back, like the feeling of water droplets crossing his skin.

His eyes lit up at this time, he didn't expect that there would be such an operation, it was amazing.

"Just now, the teacher took a pencil and drew a line behind my back, but it was pure yang qi?" Han Yi asked.

"Yes, the Pure Yang Qi is infinitely useful, but there is also a time limit, within a few days, this line will disappear, you have to hurry!" Sun Yushu told Han Yi.

"I will!"

Han Yi nodded, knowing that such an opportunity was a once-in-a-lifetime opportunity, thinking that the third ancestor had been extremely poor all his life, it was just to get through Xiao Zhoutian, and the price he paid in this way was to scatter his family wealth.

"Teacher, is there anything you need me to do for you?" asked Han Yi.

He knew that Sun Yushu didn't need to do his best to teach him the method of opening up the life gate acupoint, not to mention that he had just used the pure yang qi to tattoo a short section of the route of the Du Pulse on his body, and in doing so, he must have something to ask for.

"Yes, but not now, in the future, you will be successful in cultivation, I'm telling you. Sun Yushu said with a smile.

"Good!"

Han Yi nodded.

Saying goodbye to Sun Yushu, it was dinner time, Han Yi didn't go to the cafeteria to eat, nor did he go back to the fourth shift, but returned to the dormitory.

Why not strike while the iron is hot?

At this time, the dormitory building is closed, and it will only be opened after the lunch break and evening self-study class.

Han Yi naturally has a way to get in, he often runs out of the small window of the toilet in the morning for morning exercises, and he is already familiar with the road, at this time he came to the toilet position of the dormitory building, swept left and right, and found that there was no one, and then he flashed into the dormitory building.

After entering the dormitory, Han Yi didn't hear that the dormitory uncle opposite was in the house, so he should have gone out to eat, so he walked back to his dormitory generously.

When he came to his bed, Han Yi directly took off his shoes, sat cross-legged on the bed, and began to impact his waist and Yu acupoints.

The breath settled, Han Yi's mind quickly entered the dantian qi sea, at this time Han Yi's dantian, the qi sea was already full of pure yang qi, Han Yi felt that as soon as his consciousness approached the dantian, he was wrapped in a very warm breath, he seemed to be wandering naked in a hot spring, very comfortable.

As soon as his mind moved, he went directly to the tail pass, at this time, the tail pass was like a spring, the pure yang qi turned into nourishing spring water, and constantly came out through the ten sacral canal holes, and when Han Yi's consciousness came here, it was as if he had added heat energy to the spring water, and all of a sudden the pure yang qi boiled.

With this feeling, Han Yi immediately urged the pure yang qi to rush towards the waist Yu acupoint, and at this time, Han Yi was able to thoroughly understand the importance of Sun Yushu's painting of the Du Mai acupoint behind him.

The pure yang qi was like hot water under the urging of his consciousness, but the meridians of the Du Mai Acupoint drawn by Sun Yushu behind him were like ice crystal chalcedony, so that Han Yi's pure yang qi was involuntarily attracted to it, and then burst out all the way up from the tail Lu Pass along the Du vein.

Han Yi didn't expect things to be so simple, the pure yang qi went all the way up, and directly arrived at a pass, that is, the location of the waist Yu acupoint.

Click!

If the tail acupoint is opened like a big drum and thunder, then the waist Yu acupoint is like pushing to the fence, the sound is very small, and the pure yang qi penetrates the obstruction of the waist Yu acupoint like a sharp sword, and rushes in.

Han Yi was overjoyed when he saw this, and without thinking about it, he urged the pure yang qi to rush towards the waist yang pass, and rushed open this acupoint in one go.

The pure yang qi came out directly under the command of Han Yi's consciousness, but Han Yi still noticed that the amount of pure yang qi was much less than when it gushed out from the tail Lu pass.

But Han Yi thought that this should be a normal loss, just like pumping water to water the vegetable garden at home, and the water has watered the vegetable field, it will inevitably reduce the loss, and the soil potholes will inevitably intercept and absorb some, and the reason should be the same.

Han Yi thought about it slightly, and the pure yang qi had already rushed up along the meridians of the Du Mai from the waist Yu acupoint, and the waist yang pass.

The lumbar yang is located on the posterior midline of the lumbar region, in the depression under the spinous process of the 4th lumbar vertebra.

Han Yi had already felt the pain, different from the way the Waist Yu acupoint was opened, the moment the Waist Yang Pass was rushed open, Han Yi felt a tingling sensation in his body that flashed away, similar to the feeling of Sun Yushu stabbing his acupoint with the tip of a pencil, but by the time the pure Yang Qi poured into the acupoint, this stinging sensation had disappeared.

What followed was a feeling of refreshment that the pores of the whole body were transparent, as if the dust on the body had disappeared all at once, the whole person was as neat as new, and the whole body was overflowing with a sense of satisfaction.

"Unexpectedly, the opening of the two acupuncture points actually made me feel as light as a swallow, but this should be a physical illusion, after all, when a person is born, the acupoints of the whole body are open, and my body has opened up the dantian, the sea of qi, the tail lu, the waist Yu, and the waist Yang The whole five acupoint passes, especially this one, is to open up the two acupoint passes one after another, so I have an illusion. ”

"I remember that when the third ancestor was alive, he said a sentence, called Xiao Zhoutian, and Da Zhoutian is returning to the innate nature, and this should be the case. ”

Han Yi still thought about the pure yang qi and rushed towards the life gate acupoint, but somehow, after the pure yang qi rushed through the waist yang pass, he just arrived at the door of the life gate point, as if he had no strength, no matter how Han Yi urged, he failed to break through the life gate point.

"Anyway, the two acupuncture points have been opened one after another, and I should also take a rest, and I can't be in a hurry. ”

Han Yi also calmed down, opened his eyes and saw that the sky was already dark and he couldn't see his five fingers, and after waiting for a while, his eyes adjusted to the darkness and saw the things around and outside clearly.

Suzu!······

"Unexpectedly, when I opened the two acupoints, it was already the end of the three evening self-study, and three hours had passed, and I really didn't know that I was a guest in my dream······"

Han Yi heard the sound of the dormitory building door opening, and the sound of the dormitory building's uncle's footsteps echoing in the corridor.

"Forget it, go to sleep!"

Han Yi pulled the quilt and fell asleep directly.

······

In the art classroom the afternoon of the next day, Han Yi walked in front of Sun Yushu with a smile on his face.

"Oh, I didn't expect you to be so fast, Waist Yu Acupoint, Waist Yang Pass was opened so quickly, I thought it would take you two to three days to get through, it seems that I underestimated you. ”

Sun Yushu saw that Han Yi's breath was circulating, and the pure yang qi was rising and falling in the lower half of his body, and he could naturally sense that Han Yi had just opened the two acupoint passes, and he couldn't help but look surprised and slightly stunned.

"Come with me to the office after class!" Sun Yushu said to Han Yi for a while, then put away his eyes and continued to arrange the still life.

Han Yi continued to draw horizontal and vertical diagonal lines on the drawing board, and after class, he followed Teacher Sun Yushu to the office of the art group.

After entering the classroom, Sun Yushu searched for his office for a long time before he pulled out a thick kraft-colored paper roll of a textbook.

"Huh?" she handed it to Han Yi directly.

The kraft paper handed by Sun Yushu had two very obvious dividing lines on it, one side was pressed into the pile of books, and the other was covered with dust, very light in color, gray and gray.

"What is this?" Han Yi asked Sun Yushu with the dark-colored side.

Sun Yushu clapped his hands, knocked off the dust and said: "This is the Xiuzhen Diagram, the rubbings of Baiyunguan's "Xiuzhen Diagram"!"
