Everyone was having a great time drinking and eating meat, and chatting happily. The whole hall was filled with an extremely harmonious atmosphere.

The banquet lasted until the afternoon and everyone was satiated.

After the show ended, everyone said goodbye and left Liuquanju.

Li Xuanfeng and his daughter sent off many guests with thoughtful etiquette.

Su Yuan also drank a lot of wine, and even the use of magic power could not relieve the drunkenness, so he hurriedly said goodbye to his master and senior sister, returned home and fell asleep while he was drunk.

…………

The next day.

Su Yuan came to the Alchemy Hall for duty. After handling the daily affairs, he went to his alchemy room and took out the materials for refining the Foundation Establishment Pill.

According to the proportion, Su Yuan prepared five parts of the materials for refining the Foundation Establishment Pill, and each part can be used to refine ten Foundation Establishment Pills.

Su Yuan placed the spiritual firewood under the alchemy furnace, cast a spell, and burned a hot flame.

After preheating the alchemy furnace, Su Yuan put in the spiritual herbs and water in order and refined the Foundation Establishment Pill.

Since the process of refining the Foundation Establishment Pill is relatively complicated, Su Yuan is careful in every step and does not dare to slack off at all.

Three days passed like this.

"Open!"

Su Yuan opened the alchemy furnace, and ten gray elixirs floated out, and a strange medicinal fragrance hit his face.

Seeing this scene, Su Yuan was not only not happy at all, but also frowned.

The finished Foundation Establishment Pill should be a pure white color, but the one in front of you is gray.

There is no doubt that Su Yuan's refining failed.

Su Yuan had never failed in the art of alchemy before, and all ten pills were scrapped.

"No wonder Foundation Establishment Pills are so rare. Even with my level as a senior alchemist, I failed!"

Su Yuan is extremely confident in his talent, but every spiritual herb that passes through his hands will become a panacea.

However, this failure did not dampen Su Yuan's confidence.

On the contrary, it made Su Yuan fall into thinking.

There must be a reason for the failure of alchemy, which is related to many factors and needs to be investigated.

Su Yuan patted the storage bag, and several alchemy books appeared in his hand, and he started browsing the information on the spot.

After some searching, Su Yuan found that both the materials for refining the Foundation Building Pill and the temperature of the flame were very consistent with the descriptions in most of the elixir books.

Even the quality of the alchemy furnace used to refine the Foundation Establishment Pill meets the specified standards.

However, the methods of refining the Foundation Building Pill are different in each elixir book.

Based on his own habits, Su Yuan combined the refining method that he thought was the most reasonable, but errors still occurred.

"Is it because my method of refining the Foundation Establishment Pill didn't work correctly?"

Su Yuan finally came to the conclusion that every alchemist has different experience and skills, so there are many different methods for refining the foundation-building pill.

Therefore, the world of cultivation does not have the most standard teaching materials for refining the Foundation Building Pill.

Su Yuan believes that if all conditions are met, even a blind man can still refine various miraculous medicines.

Most of the reasons for the failure of elixir refining are errors in the method. Once there is a mistake in a certain link, the elixir will be useless.

"It seems that I can only explore by myself."

Su Yuan took out a pen and paper and displayed the processes of various spiritual herbs. Based on his understanding of the characteristics of each spiritual grass, he made subtle modifications to some of the processes.

"This time, maybe we can do it."

Su Yuan made a draft and continued refining it in his own way.

Three more days passed like this.

When Su Yuan opened the alchemy furnace again, ten gray and white elixirs emerged.

This time it still failed, but it made great progress, because this time the color of the elixir began to change from gray to white.

Su Yuan picked up the elixir and examined it carefully. He saw that it was 30% gray and 70% white. This showed that his guess was completely correct. There must have been an error in a certain process, so this situation occurred.

"Right..."

Su Yuan took out the gray foundation-building pill that he had made for the first time, smelled the smell of the two waste pills, and became thoughtful.

"This smell...could it be..."

Su Yuan hurriedly opened the alchemy book and looked up the information.

Not long after, Su Yuan slapped his thigh hard and laughed loudly: "So that's it! That's what happened! There is a problem with the order of the fusion of the spiritual herbs. Every time a kind of spiritual grass is fused, the properties of the spiritual elixir will change.

, so the drug reaction must be taken into account and the heat must be readjusted!"

"The fusion reaction of these spiritual herbs is not calculated in the elixir book, so there are many different refining methods. Although there are not many mistakes, they are not pharmacological in nature, so there is an element of luck. Good luck.

If you can succeed, if you are unlucky, you will fail."

Su Yuan was so excited that he quickly wrote down his thoughts and modified the key steps and sequence in detail.

"This time, we will definitely make it!"

…………

It’s the ninth day in a blink of an eye.

Su Yuan gently opened the alchemy furnace, and seven snow-white elixirs finally appeared. Both in color and aroma, they were no different from the finished Foundation Establishment Pills.

The other three pills are gray and white waste pills.

This shows that Su Yuan has figured out the most correct way to refine the Foundation Building Pill. As long as he continues to refine it in this way and sums up experience, he can increase the success rate.

"Success! I succeeded!"

"I have overcome the real problem of refining the Foundation Building Pill, haha..."

Su Yuan felt comfortable and happily accepted the Foundation Establishment Pill. Then he recorded his successful refining process, constantly analyzed and summarized it, and improved the most error-prone key steps.

"Keep up the good work!"

Su Yuan was full of fighting spirit and continued to refine the fourth and fifth foundation-building pills.

In the next six days, Su Yuan successfully refined these spiritual herbs into foundation-building pills. Such an incredible success rate was beyond the reach of even those masters who are famous for their alchemy skills.

You must know that the Foundation Establishment Pill is an extremely difficult elixir to refine in the world of cultivation. However, in Su Yuan's hands, after mastering the most precise method, there is a 70% to 80% success rate.

While refining the last Foundation-Building Pill, Su Yuan accidentally exploded a high-grade Foundation-Building Pill, which made Su Yuan excited for a long time.

The top-grade foundation-building pill is the most effective. After a cultivator in the Qi-refining stage with the three spiritual root attributes takes it, the success rate of foundation-building will be as high as over 90%!

Su Yuan believed that it would not be difficult to sell this high-grade foundation-building pill for a high price of two to three thousand spiritual stones.

According to statistics, Su Yuan harvested twenty foundation-building pills from his own elixir refining.

It is really scary for a cultivator in the Qi refining stage to possess such a large number of foundation-building pills.

However, from another perspective, how bad a person is to have to use so many Foundation Building Pills?
