After half a month, he was promoted to the fourth level of fighting Qi, and after a month and a half, he was promoted to the fifth level. I'm afraid that even Xiao Yan in the past could not catch up with this unparalleled speed of cultivation.

Although it is said that the difficulty of promotion will increase with each level of fighting Qi, judging from the current speed, it should not be too difficult for Xiao Yan to cultivate the seventh level of fighting Qi in one year.

Of course, under this premise, there must be sufficient base building spirit liquid. Otherwise, before Xiao Yan can reach the seventh stage of fighting Qi, he will be seriously injured and die in the training of old Yao. After all, if there is no repair effect of base building spirit liquid, there is no other way for Xiao Yan to go except for death due to excessive blood clotting.

Therefore, what Xiao Yan needs to do now is to buy materials again and then refine the base building spirit liquid. It seems very simple to say, but Xiao Yan has encountered a big problem... He doesn't have much money.

Sitting on the bed, Xiao Yan's small face was full of bitter smile. He didn't expect that he would be forced to look like this by money. He stretched out his fingers and calculated little by little... There are more than 900 gold coins left over from the last purchase of materials. It is obviously not enough to use this money to purchase the materials of those grades.

Holding his chin for a moment, Xiao Yan turned his eyes and suddenly asked: "teacher, can you use purple leaf orchid or bone washing flower with a lower year?"

"Yes, but the medicine will be weak. The base building spirit liquid I prepared for you is made with the best combination." In the ring, the sound of old medicine came out.

Blinking his eyes, Xiao Yan chuckled: "it doesn't matter. I'll use the worst materials this time."

"The worst? The effectiveness is poor. In that case, you may need half a year to break through the next period of fighting." Old Yao's voice was slightly discontented. He must have frowned at this time.

"Not enough money? Go to find that little girl. With her background, it's just a small matter to give you tens of thousands of gold coins. If you can't, ask your father for it. Why should you reduce the medicine to delay your cultivation..."

After listening to the advice of old Yao, Xiao Yan shook his head helplessly: "you can't think that my boring self-esteem is causing trouble. How can you go to a girl to borrow money again and again? My father has forgotten it. I have been hiding from him for two months. Besides, if I ask him for money, he will inquire after the truth. Wouldn't you tell the teacher about you?"

"Teacher, can someone else configure this base building spirit liquid?" It seems that he remembered something. Xiao Yan suddenly frowned and asked.

"Hey, little fellow, there are countless medicinal materials on the mainland of fighting Qi. If you want to configure pills with different effects, you must select medicinal materials that can neutralize the rage energy in the magic crystal you need to refine from among the countless materials. Only in this way can you successfully refine the pills you need. If you make a random patchwork, it will be a small matter to destroy the pills. In case of a counterattack, hey..." at this point, the old medicine Yin smiled, Then he continued: "this Zhuji Lingye is a prescription that I have refined after several years of experiments. Of course, maybe other people can make this prescription by mistake, but the probability is too small."

"Moreover, in the process of refining, the fusion degree and weight of the three materials and the concentration of the flame need countless experiments and super soul perception to grasp. Otherwise, why do you think that every pharmacist needs a teacher's hand-in-hand guidance? It is basically impossible to become a powerful pharmacist without the guidance of a famous teacher. Otherwise, the experimental prescriptions alone will cost your generation The time of the child. "

"Therefore, I dare not say about the whole mainland of fighting spirit, but I can guarantee that no one can refine the same base building spirit liquid as me in the gama empire!" At this point, there is a sense of pride in the words of old Yao.

Some people were shocked by the complexity of the base building spirit liquid. Xiao Yan subconsciously licked his lips. When he saw the old medicine refining, he seemed to realize that it was very simple. Now, he knows that the refining of the pill is much more than what he saw on the surface.

The world of medicine refining is indeed vast and unpredictable. No wonder it will become the most noble profession on the mainland.

After the shock, Xiao Yan felt a little happy. He pursed his lips and said with a smile: "teacher, I'm not going to use the worst base building spirit liquid for cultivation. I'm going to auction it. I'm not rich now. We'll buy better materials when the money is available. Anyway, it's just a piece of cake for you to make the base building spirit liquid. How about?"

"Well... It's up to you. It's not unusual for a pharmacist to auction his own elixir. Besides, the base building spirit liquid is only the lowest level of cultivation medicine. It's OK to sell it." After a little silence, yaolao said nothing.

Listening to the old black nodded and agreed, Xiao Yan smiled and packed up his things. He rushed out of the room in a hurry.

Because he didn't need too good medicinal materials this time, Xiao Yan just randomly selected the lowest year purple leaf orchid and bone washing flower from the medicinal materials store. As for the wood magic crystal, he also bought the cheapest green wood mouse magic crystal after several checks.

After buying the necessary materials, Xiao Yan found an inn and hid in it. He asked the old medicine master to refine Zhuji spirit liquid.

This time, the base building spirit liquid is not only less powerful than last time, but also its color has changed from crystal clear jade to mottled green

Put the base building spirit liquid with Xiao Yan's half fist into the previously bought white jade vial, and Xiao Yan was relieved.

After putting the jade bottle close to him, Xiao Yan left the Inn and went to the largest auction house in the city.
