Lu Yao opened the medicine refining cauldron in front of him, and then put the first herb into the medicine refining cauldron.

After the medicine refining cauldron was covered, the power of Qi and blood began to be transferred into the medicine refining cauldron.

The rune pattern on the cauldron was lit up, and the temperature inside the cauldron was getting higher and higher.

From the very beginning of the refining process, Lu Yao already felt that it was more difficult.

"This herb is really hard and difficult to refine. This first herb put into the medicine refining cauldron is the least tough among the five herbs." Lu Yao thought to himself.

He felt that the difficulty of refining this first herb put into the medicine refining cauldron was no more than that of the toughest herb among the five herbs used to make bigu pills.

This was much more difficult to refine than he had predicted before.

I originally thought that it was also the first herb, and that the first herb used to refine the Blood Qi Pills should only be 20% tougher than the first herb used to refine the Bigu Pills. Three achievements would be pretty good.

But now after trying it, I found that the toughness and strength are almost doubled.

When Lu Yao once again increased the output of his energy and blood, the first herb began to be refined.

After more than 5 minutes passed, Lu Yao started to open the medicine cauldron and put in the second herb.

His energy and blood force also split into two streams.

As more and more herbs were placed, the load on his Qi-blood relay also became greater and greater.

It was also the step of fusion of herbs. Lu Yao felt that the consumption of his own energy and blood was more than twice that of refining Bigu Pills before.

A group of dark green liquid appeared in the medicine cauldron, which was the product of the fusion of five kinds of herbs.

But not until Lu Yao started to remove the impurities in the liquid medicine.

There was a burning smell coming from inside the medicine refining cauldron.

This means that the pill refining failed this time.

"It failed! It really failed." Lu Yao sighed.

"Obviously they are all elementary levelless pills, but why is it so much more difficult to refine the Blood Qi Pills!"

"This is just the Blood Qi Pill. The Chaoyi Pill is more difficult than the Blood Qi Pill."

He could feel that his qi and blood power was being consumed a lot. He had just completed the fusion step, and 70% of his qi and blood power had been consumed.

This was already more expensive than the time it took him to complete the refining of Bigu Pills.

Of course, he also understood in his heart that the reason why he had such consumption was because he was not very skilled in refining blood energy pills and was still very unfamiliar with the entire refining process.

However, Lu Yao was not discouraged. After the power of qi and blood was restored, he tried refining the blood qi pill again.

This time it still ended in failure.

"If I continue at the current pace, I'm afraid it will take me another two months to complete the refining of the Blood Qi Pill. After two months, the semester will be over." Lu Yao thought to himself.

"If we use a high-level stepless medicine refining cauldron, we should be able to complete the refining time of the Blood Qi Pills by about half a month earlier."

"But it's still too late. I want to complete the refining of the blood energy pill as soon as possible."

It was already 5:00 pm, and Lu Yao stopped refining pills.

He and his friends left the dormitory and headed to the cafeteria to have dinner.

After dinner, everyone returned to the dormitory.

Lu Yao took out the medicine refining cauldron from the room again and began to refine the blood energy pills.

After trying the refining twice more, it still failed.

But he can already start trying the impurity removal steps.

"That's it for today. After I exchange the stepless advanced medicine refining cauldron tomorrow, I will continue to try to refine the blood energy pills." Lu Yao thought to himself.

"If you use a stepless advanced medicine refining cauldron to refine pills, the efficiency should be improved very quickly."

I tried to refine blood energy pills twice, and it was only around 8pm.

In the following time, Lu Yao began to practice elementary sword skills and water source combat skills.

After using the water source in the water bag as a medium, he could now barely perform the seventh form of the water source combat technique.

But it's just barely.

He needs to continue to practice a lot to become more and more proficient in this set of water source combat skills, and also to consume less energy and blood in the process of performing water source combat skills.

After completing another practice of water source combat skills, the power of Qi and blood was exhausted again.

He sat cross-legged on the ground and began to practice breathing techniques to restore the consumed energy and blood.

In the process of practicing the breathing method, the bottleneck period of Qi and blood will also slowly loosen, but the speed of this loosening is very slow.

Lu Yao's current training intensity is actually very intense, and he has the support of the intermediate blood energy pills provided by the academy.

Even if he continues to train like this, he is confident that he will break through the 50-power bottleneck period and reach the level of a high-level trainee warrior within half a year.

But it was still too slow for him.

After completing a breathing exercise, Lu Yao's energy and blood power had almost recovered.

He began to practice the second and third water source combat skills.

By the time the three water source combat skills exercises were over, it was almost eleven o'clock in the evening.

"It's almost 11:00 now. Let's stop training. Our training session ends here." Lu Yao reminded loudly.

We are about to reach the last key class challenge of this semester, and everyone is accustomed to increasing the intensity of training and increasing the training time.

All the partners stopped training.

"Tomorrow morning, I need you to accompany me to the ghost-slaying team." Lu Yao said to several people.

"The number of bigu pills I have refined now is enough. I am going to exchange these pills for points tomorrow. Then you can lend me some points, so that I can exchange them for the high-grade medicine cauldron I want.

Already."

"I can also start trying to refine blood energy pills."

"I believe that if you give me about a week, I should be able to complete the refining of the Blood Qi Pill."

"Then you won't have to worry about lack of pills."

"No problem, of course we hope you can refine the Blood Qi Pills as soon as possible." Lei Ming said with a smile.

"After all, if you can refine the Blood Qi Pills sooner, we can benefit sooner."

"The remaining points we have will be used to redeem pills anyway."

"It's twice as cheap to exchange pills with you. Speaking of which, we still make a profit!"

Lu Yao's goal is to successfully refine the Blood Qi Pills in about a week.

Of course, it is definitely not possible to complete this step just by relying on the stepless advanced medicine refining cauldron.

There is still gray airflow in Luyao.

If the gray airflow is consumed, it should be possible to complete this step.

"Then you go and have a rest early. You have to get up early tomorrow." Lu Yao said to several people.

Several friends said goodbye to Lu Yao, left his dormitory, and returned to their own dormitories to rest.

After everyone left, Lu Yao also went to wash up and rest.
Chapter completed!
