After breakfast, Ling Jiang made an excuse and walked towards Pinghai Town.

Perhaps because the tidal anomaly was fading, Ling Jiang found that there were many fewer outsiders in the town than in the previous two days. It is estimated that as Xi Yao said, the tide is high, and the possibility of wanting to touch the baby is even lower, so naturally no one wants to spend time here.

He traveled to the school with ease.

"Mr. Su?" The school was still open, but Ling Jiang walked in and found that Su Qiuhe was not inside.

He came behind the statue of Confucius and found that the small door was also tightly locked, and it was obvious that Mr. Su was not in it.

Ling Jiang then walked to the bookshelf to the side, rummaging through the books. Su Qiuhe had told him before that as long as he wanted to read, he could come to the school at any time, but the books in the school were naturally not as rich as the books in the bookstore.

It is said that the ancestor of the bookstore shopkeeper was also a reader, but he was not from Pinghai Town, but migrated from other places, came here to sell books, and lived an ordinary life, and this bookstore has been passed down from generation to generation.

Although the business is bleak, after all, the family is rich, and there are many scholars in the town, and life is quite passable.

Ling Jiang went to the bookshelf and rummaged through it, and accidentally caught a glimpse of an old yellowed book, which, unlike the others, was obviously old.

Ling Jiang took down the book, and even the title of the book was blurred, and he couldn't help but feel a little strange.

It stands to reason that this kind of book should be placed in a bookcase for good collection, how can it be placed in the school for anyone to read? What if it is accidentally broken?

He cautiously turned the first page, only to see two big and exciting words revealed: washing the marrow.

"Isn't it, is that okay?" Ling Jiang looked stunned.

"The so-called marrow washing is to remove the impurities accumulated in the human body for many years. People are born like white jade, but once contaminated with meat, white jade will no longer be pure, over the years, if the impurities in it attack the heart together, it is enough to make people die. Therefore, the ancients tried in every possible way to create a medical technique called marrow washing......"

Ling Jiang flipped through it carefully, and on the first page of this book, he explained clearly what it means to wash the marrow, how to wash the marrow, and what will happen to the marrow. The most commonly used of these are pharmacology and Tongmai.

It is quite difficult to open up the meridians around the body by a master, so that the impurities can be turned into turbidity and eliminated from the body.

Therefore, most people who say pulp washing refer to pharmacology.

"No wonder Miss Xi Yao is reluctant to mention the marrow washing to me, there are more than a dozen kinds of medicinal materials listed on it that I have never heard of, let alone can be found in this town. Ling Jiang smiled bitterly, it seemed that washing the marrow would not work.

Ling Jiang then turned the next page, and the first line of words on the tree made him feel whim.

"It is quite difficult to find the above medicinal materials, so it is not necessary to follow this recipe to find medicine. Since it is pharmacological, the efficacy of the medicine will also affect the degree of marrow washing, if the conditions do not allow, you can also reduce the quality of the medicinal materials to wash the marrow, of course, so that the effect of marrow washing is naturally not as good as the former. ”

Then, the book lists three different kinds of medicinal herbs, which are divided into excellent products, good products, and defective products.

Ling Jiang glanced at it and found that with his current financial resources, he could only scrape together enough inferior medicinal materials at most.

"Defective products are defective products, it is better than nothing. He muttered to himself, carefully putting the yellowed old book back in its place, and then left the school and hurried to the pharmacy.

Xi Yao left twenty taels of silver, and before going out, he brought one tael, which was enough to buy the next batch of medicinal materials. As for good products, even if they can be bought for twenty taels, they must be sold in Pinghai Town.

Ling Jiang went to the pharmacy, spent 700 wen to buy the medicinal materials one by one, and returned home with the medicine bag apprehensively.

He pushed open the thatched hut, Ya'er was not at home, and guessed that he had gone out to buy vegetables.

He couldn't wait to get the casserole, cleaned the herbs, and put them on the stove to fry them slowly over low heat.

According to the book, it takes two hours of decoction for the medicinal effect to come out.

Ling Jiang waited from midday to sunset.

"It's strange, it's so late, why hasn't Ya'er come back yet?" Ling Jiang couldn't help but feel a little worried as he looked at the sun setting in the west.

He looked at the country road and was a little flustered, until he saw the white-clothed figure walking briskly, Ling Jiang breathed a sigh of relief in his heart.

"Childe, are you hungry?" Ya'er came to Ling Jiang's side and said apologetically, "Ya'er will cook for you." ”

"Where have you been, why did you come back so late?" Ling Jiang asked.

Ya'er hid her hand behind her back and looked down to think about something. Ling Jiang grabbed Ya'er's little hand, only to see that blisters had formed on this slightly rough palm.

"Tell me honestly, what have you done?" Ling Jiang asked.

Ya'er thought for a while, and said with a smile, "Ya'er, I'm going to wash people's clothes, and I'll give you 500 wen a month!"

"Mess around!" Ling Jiang couldn't help but scold.

Listening to Ling Jiang's scolding, Ya'er was a little scared, bowed her head and said, "Childe, Ya'er is not afraid of being tired, Ya'er still has to save money for you to get a daughter-in-law." ”

Listening to Ya'er's words, Ling Jiang suddenly felt that he was a little unprofessional. is a big man, and he actually wants to let the maid work to support the family.

"Obedient, don't go in the future, stay at home honestly, and make money, I will find a way. Ling Jiang said.

"Hmm......" Ya'er replied with her head down and a vague nod.

She suddenly looked at the casserole on the stove, and a smell of medicine wafted from it, "Childe, are you decocting medicine?"

"It's a conditioning prescription written to me by Miss Xi Yao. Ling Jiang said lightly.

"Miss Xi Yao. Ya'er muttered in a low voice, and walked towards the hut.

Ling Jiang pinched the sweat in his palms, but fortunately he got this matter over. He found a porcelain bowl and poured out the decoction in the casserole, only to find that there was only one bite left.

"That's a bit too ruthless. Ling Jiang looked at the medicinal herbs that had been squeezed dry and said with a wry smile.

According to the book, after drinking this decoction, he will vomit and diarrhea, and black stains will grow all over his body, and the whole body will stink, so as to eliminate impurities, so Ling Jiang drained the bitter decoction in one gulp, and ran to a stream, so as not to let Ya'er see his embarrassing appearance for a while, and take a bath and go back by the way.

When Ling Jiang came to the stream, he didn't feel any discomfort except that he felt some bloating in his stomach.

"Strange, could it be that I drank a fake medicine?" Ling Jiang couldn't help but wonder, "Maybe the effect of the medicine hasn't taken effect yet, I'll wait and see." ”

He wandered for a while, for about a quarter of an hour, but nothing unusual happened.

"What the hell is this......" He was stunned, looking at the sun slowly sinking into the west in the distance, a little confused.

"By the way, this should be going to be low tide. Ling Jiang thought to himself.

When the tide is low, it is the time when the tidal aura overflows, and now that the tidal vision is about to recede, Ling Jiang recalled the set of roads Xi Yao took today, and took a horse step.

Inhale, punch, close, exhale......

When he had completed this set of Naling paths, he returned to his place and let out a long breath of turbidity.

Then take a breath.

"Huh?" Ling Jiang couldn't help frowning the moment he inhaled.

The breath he inhaled seemed to be a little cold, like the smell of the sea breeze, a little fragrant, and there was no trace of fishy smell.

This feeling is like the qi that is inhaled in the body on a normal day, and it is a little different.
