On the way to the pharmacy, I absorbed more than ten wisdom crystals.

After inquiring about the price of medicinal materials in the pharmacy, Niu Buyi was very satisfied, he didn't expect that a payment of Shenggen Dan's medicinal materials would only cost three taels of silver.

After directly buying three medicines, Niu Buyi walked into the distance until he came to a civilian area in the northwest corner of Zhiyun City, which was three or four miles away from his house. Because they are all poor people in this area, and the houses are all dilapidated, it can also be regarded as a slum. In one corner, there was a small courtyard with a collapsed wall, and the houses inside were also dilapidated.

At the moment, there are a few children playing inside.

The gate of the courtyard was gone, only the walls on both sides remained, and Niu Buyi walked in from the courtyard gate.

"Ah, the boss is here." A child shouted happily when he saw Niu Buyi.

Several other children also gathered.

The eldest of these children was only 11 years old, and the youngest was 6 years old, the same age as Niu Buyi.

"Boss, didn't you give us food in the morning? Why did you bring food again? The eldest child came up and said.

"Da Niu, don't look at everything to eat, this is not rice, it is something I use. Go and wash your pot for me, I'm going to boil the medicine. ”

There was not even a stove in the house, it was originally there, but it had collapsed. The so-called pot is a casserole with a broken piece.

The fire was lit in the courtyard, the casserole was filled with water, and Niu Buyi sorted and put a portion of medicinal herbs into it according to the prescription.

There are two ways to refine Shenggen Dan, one is that it can be used by simple boiling, but what comes out is only the medicinal liquid, in which the loss of medicinal effect is relatively large, and one medicinal liquid can only be drunk for one day. If you want to refine the pill, you should take at least four pills at a time, and you can eat one pill a day.

That is, a medicinal herb, if it is made into a medicinal liquid, it can only be used for one day, if it can be refined into a pill, it can be eaten for four days, and the difference is that it is lost when boiling the medicinal liquid.

It's just alchemy, you need a Dan furnace, you also need a fire spirit stone as fuel, and more importantly, you need to learn alchemy. Although there is a method of alchemy in the prescription, Niu Buyi now has no vitality in his body, and he can't even ignite the fire spirit stone, so he can only boil the medicinal liquid to drink it first.

It took more than an hour for a liquid to boil.

"There is still a crystallization of wisdom in this potion?" Looking at the numbers above the liquid medicine, Niu Buyi was really a little surprised. There are quite a few wisdom crystals contained in the liquid medicine, and there are seventy-three points.

Niu Buyi stretched out his hand to absorb the wisdom crystals before drinking the medicinal liquid.

After drinking the medicinal liquid, Niu Buyi felt that his body was hot, and the effect was much stronger than that of practicing the root promotion technique.

After a while, the feeling of the medicinal effect dissipated, and Niu Buyi made a few movements to probe his roots.

"It works so well?" Niu Buyi was extremely surprised, and now his root bones had directly reached the lower grade of Huang.

Niu Buyi practiced the root ascension technique yesterday, and he practiced it again this morning, and he could feel that the root ascension technique had improved his root bones, but it was not enough to reach the lower grade of Huang, but after drinking a medicinal liquid, he actually improved directly.

"The prescription says that the higher the root bone level, the slower the improvement, maybe it is also because my root bone level is too low, so the medicine has been upgraded by a grade."

At noon, Mrs. Liu came to her family and brought lunch.

In the afternoon, Niu Buyi lay on the only small wooden bed built in this small courtyard, creating his own exercises and brushing up on post-class questions. In the evening, I went home for dinner, and this was the case for three days in a row.

When he went home that night, his father Niu Hong and second brother Niu Hengyi had already arrived home first.

Seeing Niu Buyi coming back, Niu Hengyi handed Niu Buyi a porcelain bottle.

"Third brother, you have started to practice martial arts, this is a gift from the second brother." Niu Hengyi handed over the porcelain vase.

"What is this?"

"Blood Qi Pill, when you are in the Blood Qi Realm, you can use the Blood Qi Pill to assist, which can increase Qi and blood, making the speed of cultivation faster." Niu Hengyi said.

It happened that Lu Caici passed by, took the bottle casually, opened it and looked at it.

"Ten Blood Qi Pills? Hengyi, who gave this to you? ”

"Mother, this is my classmate's sister heard that the third brother learned martial arts, and gave it to me, and said that to learn martial arts, you must have the assistance of the Blood Qi Pill to enter the realm quickly." Niu Hengyi said.

"He's right, but the third brother hasn't really tempered his qi and blood, and he doesn't need this thing yet, if he really needs this thing, can I still buy it for your third brother!" Lu Caici said, "The Blood Qi Pill is a military material, because it needs demon beast meat as raw materials, so the supply is mainly for the army, and the people are often out of stock.

The Blood Qi Pill is not cheap, a bottle of ten Blood Qi Pills is worth ten low-grade Yuan Stones. Your classmate is really generous...... isn't it, it's the sister of a classmate? ”

"So expensive?" Niu Hengyi stretched out his tongue, and the focus of his attention was the price of Qi and Blood Pill.

Niu Buyi's eyes lit up, and he finally heard Yuanshi's message. In addition to Yuan Shi's information, he also finally saw the elixir.

Shenggen Dan only has the pill formula, and he can only boil out the medicine liquid now, and he can't refine the pill at all, and the blood qi pill in front of him at this moment is the real pill.

Could this thing be the elixir in fantasy novels? In the novel, it is said that alchemists earn money, it seems to be true, if I also learn to refine pills, will I be able to earn spirit stones to repay the loan of the system! Niu Buyi began to think about it.

"Which of your classmates' sister is so generous?" Lu Caici's face showed an inexplicable smile.

Niu Hong also came to the front at this moment, he also heard the conversation between Lu Caici and Niu Hengyi just now, and he also looked at Niu Hengyi with a curious face at this moment.

"Xiao Qing, the sister of my classmate Xiao Han, her grandfather is the state lord Xiao Wuji." Niu Hengyi hurriedly said.

"Who's his father?"

"You know, Xiao Feng." Niu Hong said beside him.

"It turned out to be that kid, I was beaten many times when I was young." Lu Caici smiled, "Just like him, what can a girl look like." ”

"I've seen that girl, she's beautiful." Niu Hong said.

"That's okay, no wonder he can give a bottle of Blood Qi Pill casually, but his family background is stronger than ours. As the vice president of the academy, although you are stronger than Xiao Feng, you are a little worse than Xiao Wuji. However, you are younger than Xiao Wuji, and you may not be able to have a higher status than Xiao Wuji in a few years. It is quite appropriate for his granddaughter to accompany Hengyi. ”

"Mother, we are just ordinary friends, not the kind of relationship you said." Niu Hengyi said with a flushed face.

"What kind of ordinary friend can casually give a gift worth ten low-grade yuan stones. I want that kind of friend, too. Lu Caici said jokingly.

Niu Hengyi's face turned even redder.

"The Xiao family except Xiao Han is all learning martial arts, so this little girl is learning martial arts, she should follow the Xiao family to learn martial arts in the state city, why did she come to Zhiyun City?"

"I do know about this matter, Xiao Han, as the only child of the Xiao family to learn literature, was originally here alone, but a few months ago, the army in charge of Xiao Feng was transferred to our western trilateral city, because the place where he was stationed was relatively not too far from us, so he moved his family to Zhiyun City." Niu Hong said.

"What are you doing in Trilateral City? Poor and out-of-the-road. Lu Caici said curiously, "No, Sin City is next to it, Xiao Feng wants to fight Sin City?" ”

"I don't know, Xiao Feng's army has been gone for three months, and there is no movement, I don't know what he is thinking." Niu Hong said.

"Hey, whether or not to fight Sin City has nothing to do with us, what do I worry about this?" Lu Caici reacted suddenly, "Second child, how old is Xiao Qing's little girl, when will you bring your family to play?" ”

Niu Hengyi's face turned even redder.

"Sixteen years old, martial arts cultivation is not bad, I think there is a bit of your youthful demeanor." Niu Hong said.

"Mother, I'm still young, I really didn't think about what you said." Niu Hengyi said.

"It's okay, you deal with it first, and in a few years, my mother will find someone to propose." Lu Caici said, "It doesn't matter if you don't have a good impression of her, just return this bottle of Qi and Blood Pill to her." I will have less contact with her in the future. ”

"I, mother, such a valuable thing, let's return it." Niu Hengyi said hesitantly.

"If you want to return it, she will definitely be angry, and she may not be able to deal with you in the future." Lu Caici and Niu Hengyi said.

"Mother, what should I do then?" Niu Hengyi asked anxiously.

Up to now, even Niu Buyi can see that Niu Hengyi is interested in other people's little girls.

"It doesn't matter if you don't return it, my mother will prepare a gift for you as a return gift." Lu Caici said, and then turned his head to look at Niu Hong, who was watching the play next to him, "You have to work hard, at least if you are in the realm of great sages, you can compare to the old man Xiao Wuji, and you can be regarded as a good person."

If you don't fight for it, your son's daughter-in-law may be yellow, even if it is not yellow, Hengyi has no status in his father-in-law's family, and in the end, the relationship with their family is very stiff like the two of us. ”

"He's a martial artist......" Niu Honggang said here, and found that his wife's face had changed, and hurriedly changed the topic, "The food is ready, let's eat quickly." ”

Niu Hengyi still wanted to explain, but he was pulled by Niu Buyi to eat, and he didn't say anything.

"Mother, the Qi and Blood Pill is a gift from the second brother, should it be given to me?" After dinner, Lu Caici didn't give Niu Buyi the Qi and Blood Pill, so Niu Buyi had to ask for it.

He didn't need the Qi and Blood Pill, but when Lu Caici opened the porcelain bottle, he had already seen the number on the Qi and Blood Pill, more than one hundred and ten! That's the crystallization of wisdom, and it's almost all the wisdom crystals in his body now.

"You haven't officially tempered your qi and blood, it's a bit early to take the qi and blood pill now, wait a few more days, wait until you have practiced all the movements taught by the old knife, and then practiced a simple set of martial arts to temper qi and blood, before you can eat this."

"Give it to me sooner or later, give it to me today, I won't eat it, I'll eat it when you let me eat it." Niu Buyi said, "I just look at the novelty and want to take it back to play." ”

"This is an elixir, not a toy!" Lu Caici patted Niu Buyi's head dotingly, "If you accidentally eat one of these things, at least it will bleed from the seven orifices, and if it is serious, you may die." ”。

"Mother, if you don't give it to me, you can take out one and let me see it." Niu Buyi said.

"Okay." Lu Caici poured out one and handed it to Niu Buyi.
