"Of course, it's the promotion of the root and the promotion of the root." The system replied.

"What about the upgrade?"

"You need to be in the exercise bank first." The system replies to the message.

"Okay, Shenggen Dan and Shenggen Decision will help me get into the exercise bank."

Soon, there were two exercises in Root Bone Science, which were Ascending the Root Pill and Ascending the Root Decision.

Niu Buyi didn't waste time to create and upgrade it himself, but directly checked the analysis.

"The analysis of each question requires ten yuan stones, are you just for these twenty yuan stones, did you let me upgrade to the Ascending Root Pill and Ascending Root Decision?" Niu Buyi was suspicious.

The system didn't reply.

Niu Buyi had no choice but to check the analysis with peace of mind, and the difficulty of ascending to the root really increased. Shenggen Danzhong's main medicine has changed a few flavors. According to the medicinal materials he saw at the pharmacy, the price of the main medicine that was replaced was much more expensive. However, this time, the system directly prompted that an upgraded Ascending Root Pill can upgrade the root bone from the ground to the middle grade. It is equivalent to the old version of Shenggen Dan starting to eat from Huang and other inferior products, and the number of pills required for each liter of one product is still doubled.

"These main medicines, each of which is worth at least a hundred taels of silver, it seems that it is still an expensive thing that works well!" Niu Buyi sighed.

He practiced the upgraded version of the root ascension technique again, and found that it was too difficult, with his current ability, he was only able to practice this set of root ascension techniques, but he was also tired and sweaty, but the effect was also very good.

He is now a middle-grade Xuan-rank, and he has only practiced the Root Ascension Technique once, which can actually make him reach the top-grade of Xuan-rank, and he feels that he will soon be able to upgrade to the ground rank.

This made him a little impatient to use the upgraded Shenggen Pill, but was reminded by the system that it was best to wait until the ground before using it, otherwise it was prone to unknown consequences.

The days continued, but Niu Buyi only refined some Ascending Root Pills every day, and the Blood Qi Pills were left for the six little beggars to refine.

The cultivation of the six little beggars was also very fast, although at the beginning they were not suitable for using the Blood Qi Pill, because the Qi and blood produced by the Blood Qi Pill were too strong for their bodies to bear.

But Niu Buyi created a method, which was to let them hold a Blood Qi Pill in their mouths when they cultivated every day.

In this way, the medicinal effect of the Blood Qi Pill only entered the body a little bit, just enough for their body to bear, and after doing so, their cultivation speed would be very fast.

Occasionally, in his spare time, Niu Buyi went to Yunlou to listen to songs and dances, which also made him feel inconvenient, if there was something or a computer, or a mobile phone, would he be able to listen to music and dance at home.

More than ten days later, Niu Buyi was listening to music in Yunlou when he was found home by Liu Po. It turned out that his grandfather replied to the letter, and Lu Caici asked Niu Buyi to go back to discuss the matter of the Blood Qi Pill.

Lu Caici did not say in the letter that the Blood Qi Pill was refined by Niu Buyi, but only said that he had encountered this kind of Blood Qi Pill, and asked his father if he needed it, if he needed it, she could help order it, and the price had already been set, one inferior Yuan Stone and one pill.

Niu Buyi's grandfather replied that he was really very satisfied with the Blood Qi Pill, and said that he wanted as many as he wanted, so that Lu Caici must set this Blood Qi Pill for him.

"Buyi, shouldn't you increase the production of some Blood Qi Pill?" After seeing his father's reply, Lu Caici pulled Niu Buyi and said.

"Mother, the output has increased, and the number given to Sister Xiao Qing has not changed, and now I have a lot of blood qi pills in my hands." Niu Buyi said, there are six rats, and Niu Buyi arranged for them that each person can refine four pots a day.

But those six guys were very desperate, every day Niu Buyi was not there, and they were also crazy about refining pills.

As a result, they refine at least five pots every day, that is, each person makes fifty pills every day, a total of three hundred.

But what he gave Xiao Qing was eighty pills a day.

The only thing that made Niu Buyi a little restricted was that there were not many medicinal materials in the pharmacy, and he had such a large amount that he had bought several of the pharmacy stores in the entire city.

"How many do you have? I'll get a batch for your grandfather first. ”

"More than two thousand." Niu Buyi said.

"So much?" Lu Caici didn't expect the output of the Blood Qi Pill on Niu Buyi's side to be so terrifying.

"Grandpa has been replying so slowly, it's been more than ten days, and I've saved more than 2,000 pieces, which is not much." Niu Buyi said.

"More than 8,000 miles, a round trip for more than ten days is not slow, I use the military's post station, flying monsters to send messages, more than 1,000 miles a day.

If you want to be faster than that, unless you're a true realm master like your grandfather, you can fly thousands of miles a day. Can be transformed into a master of the real realm, who can specialize in running errands and delivering letters. ”

Niu Buyi wants to say that he uses a mobile phone! It's a pity that there are no mobile phones in this world.

"Well, it seems that the distance is a problem. Mother, the saved blood qi pills are all in my room, you can get them later. Niu Buyi said.

"Well, take the things in a while, let the old knife go to the northern frontier and send the blood qi pill to your grandfather."

"Daobo?"

"That's right, he was originally a soldier under your grandfather, although he was injured, he was still a master of the mountain realm, your more than 2,000 blood qi pills are not a small amount, you can't just mail it by post station, even if it's a military post station."

"That's going to toss Dao Bo once, by the way, mother, I have a set of martial arts to teach you." Niu Buyi said.

"You teach me martial arts?" Lu Caici smiled, "It's been almost a month since you started saying that you want to learn martial arts, and you've only learned a few moves in total." ”

"Mother, this is written in ancient books, and it can also improve the root bones." Niu Buyi said.

"What?" Lu Caici was stunned for a moment, "You mean really?" How to improve the root bones to you is the same as playing. No, alchemy is the same as playing. ”

Niu Buyi has already begun to move.

"It's a bit difficult!" Lu Caici looked at Niu Buyi's movements and said with some surprise, "You can actually make such difficult movements?" ”

After Lu Caici finished speaking, he remembered that Niu Buyi was eating Shenggen Dan every day, and the root bones were now improving a lot, and it was possible to be able to play difficult movements, but it was only possible, "Could it be that the root bone improvement can really make people make a lot of martial arts movements that can't be done?" ”

Of course, she didn't know that Niu Buyi could make such difficult martial arts movements, the main reason was because he had learned the content of martial arts, otherwise even if the roots were high, this kind of action would need to be practiced often.

"Mother, this set of martial arts has a total of twenty-four movements, and it can also increase the root bones, and the effect is a little better than the Shenggen Pill in your hand, I haven't practiced it well in the previous paragraph, but now I can play it completely, so I came to teach you." Niu Buyi found a reason and said.

"It's also from the ancient book you said?" Lu Caici asked suspiciously.

"That's right, it's with Shenggen Dan." Niu Buyi said.

"Then I'll try, if there's anything wrong, you can point it out to me."

The twenty-four movements are not very cumbersome, and Lu Caici read it and memorized a rough one.

After teaching it three times, Lu Caici was able to memorize all the movements.

As a martial artist of the Yuan Sea Realm, the difficult movements are not very difficult for her, and she can complete them all.

"This set of martial arts movements is really strong, although there is no vitality running, but it can make the flesh and bones of the whole body vibrate, and the most amazing thing is that the meridians seem to be widened, and there are more vitality that can be accommodated." Lu Caici said in surprise.

"Mother, just practice this set of movements every morning and evening in the future." Niu Buyi said.

"Okay." Lu Caici agreed very happily.

Then he went to get the Blood Qi Pill and asked the old knife to take it away.

Niu Buyi started his own beautiful life again.

After the old knife came back, he brought back more than 2,000 yuan stones, plus the 3,600 yuan stones that he had traded with Xiao Qing three times, he got more than 5,000 yuan stones in total.

The fire yuan stones and medicinal materials needed to refine the elixir did not use up a total of five hundred yuan stones.

Niu Buyi had money, and directly returned the system's 5,000 yuan stone. It didn't take two months in total, and the interest was naturally not much.

The life of Niu Buyi without debts has become more nourishing, and several courtyards adjacent to the beggar's courtyard have been bought by him and renovated, and now the beggar's courtyard has changed greatly.

Buying a small courtyard is not a forced purchase and a forced sale, but a price much higher than the normal price. The neighbors were also happy to sell the yard.

As for the neighbor's new home that sells the house, you can just find a dilapidated courtyard to live in, you don't need to spend money at all, in Zhiyun City, there are really some dilapidated and uninhabited courtyards, but they are all in remote locations, and no one usually occupies them.

After the new courtyard of Niu Buyi was built, there were more houses, and the five little beggars also had their own rooms, and the food and clothing were no longer the same as before.

Niu Buyi not only provided food and clothing, but also taught them various pharmaceutical knowledge, and paid them a salary every month. The lives of the five little beggars have also changed from the earth to the sky.

In fact, Niu Buyi has already stipulated for them that there are two hours in the morning, two hours in the afternoon, and rest at other times, if they are taught some knowledge, the alchemy time will be shortened.

But they just didn't listen, and they always worked overtime secretly at night, which made Niu Buyi very helpless.

Niu Buyi naturally didn't understand the little beggars' thoughts. They just hoped to help Niu Buyi refine some pills to repay Niu Buyi for these benefits they had given them.

After more than a month, the root bones of Niu Buyi were finally upgraded to the top grade.

"System, I've arrived at the heavenly grade, what is the secret of this heavenly grade? You have to wait for the root bone to reach this level before you can improve the realm? Niu Buyi didn't go to Yunlou today, but lay on the recliner in the beggar's courtyard, asking about the system in his mind.

"This secret can only be known when you have ascended to the realm."

"Okay, but how do I improve? Will you help me improve? Niu Buyi asked.

"You cultivate by yourself, of course, you improve by yourself."

"But how can I ascend to the next realm, I don't have the cultivation method for the next realm."

"Upgrade your subject knowledge." The system replied.

"Okay." Niu Buyi has forgotten to improve the subject.,It's been too comfortable lately.。。

Discipline improvement requires 100 points in after-class exercises, and Niu Buyi has scored 100 points in each subject.

"Ah, so expensive!" Niu Buyi wanted to improve the principle of exercises, and found that it took 10,000 lower grade yuan stones to improve the second-level discipline, and 5,000 lower grade yuan stones to improve the third-level discipline.
