Song Li's physique is originally different from that of ordinary people. With the help of healing pills, it took only more than two hours before Song Li treated the injuries in his body.

Seeing that Qingying and the other two were still conditioning their injuries, Song Li did not disturb him. After closing his eyes and resting for a while, he took out a roll of black jade slip from the storage bag.

This black jade slip was the spoils obtained after killing Huoshan when Song Li went to the Shiyan City controlled by the Demon King Huoshan to snatch the corpse of the Xuanbing Dragon King before heading to the Wan Yao Mountain Range.

What is recorded is a method of refining called Marrow Cleansing and Bone Refining Pill, as well as the medicinal materials needed for refining. When Huo Shan was killed, he obtained along with this black jade slip, and there was also a nine-leaf fire lotus. The nine-leaf fire lotus is one of the medicinal materials needed for refining Marrow Cleansing and Bone Refining Pill.

Because in addition to the Nine-Leaf Fire Lotus, there are also two other extremely precious medicinal materials needed to refine the marrow washing and bone refining pill. At that time, Song Li did not have the other two medicinal materials, so he could only put away the black jade slip and the Nine-Leaf Fire Lotus first, and planned to collect all the medicinal materials needed for the marrow washing and bone refining pill in the future, and then start to refine them.

This time, Song Li defeated Yin Zhenyu and got the storage bag that Yin Zhenyu carried with him. The three-heart grass and Yin-Yang Body Forging Flowers were the two extremely precious medicinal materials that were missing for the marrow washing and bone refining pill.

At this time, when he was free, Song Li began to check the contents in the jade slip. If he could successfully refine the marrow-cleaning bone pill with the existing medicinal materials in his hand, then he believed that with the medicinal effect of the marrow-cleaning bone pill, he could not only improve his body to the greatest extent, but also take this opportunity to try to attack the Linghai Realm.

To be honest, this time when fighting with Yin Zhenyu made Song Li deeply realize how powerful a strong man with a cultivation level above the seventh level of the Linghai Realm was. If he hadn't taken the huge risk to swallow 30 or forty pills to fight Yin Zhenyu at once, I'm afraid he would have been very difficult, let alone capturing Yin Zhenyu alive.

It is precisely because of understanding this that Song Li hopes to break through to the realm of the Linghai Realm as soon as possible, and taking the marrow-cleaning bone refining pill is undoubtedly the best way.

"I didn't expect that the marrow-cleaning and bone refining pill would be so cumbersome to refine! Now the medicinal materials in my hands are only enough to refine them once. If the refining fails, the loss will be great!"

After reading the content recorded in the jade slip in detail, Song Li couldn't help but feel hesitant.

The steps for refining this marrow-cleaning bone pill are very complicated. You need to extract the most essence of the Nine-Leaf Fire Lotus, Three Heart Grass and Yin-Yang Body Forging Flowers, and then add some other medicinal materials to help them. Finally, you can refine them successfully.

Even with Song Li's alchemy technique, he could not guarantee that he could successfully refine the marrow-cleaning bone refining pill in one go. At this time, Song Li couldn't help but he hesitate. Now the medicinal materials in his hands are only enough for him to refine them once. If this refining fails, he will not only not be able to obtain the marrow-cleaning bone refining pill, but also the three extremely precious medicinal materials in his hands will be destroyed.

For alchemists, as long as it is a very high-quality pill, it will be accompanied by a significant chance of failure when refining. No one can guarantee that the first time you can refine a certain elixir of extremely high-quality pill will definitely succeed.

Generally, when alchemists refine some extremely high-quality elixirs, in order to be on the safe side, they will prepare medicinal materials that are at least enough for him to refine them. In this way, he has two chances of failure and can find the reason, and then strive to successfully refine the elixirs during the third refining.

However, the problem facing Song Li is that the medicinal materials he has only enough for him to refine them once. If the refining fails, he will not even have the chance to refine them for the second time.

The nine-leaf fire lotus, the three-heart grass and the Yin-Yang Body Flower are all hard to come by. It has been more than a year since the Nine-leaf fire lotus and the Jade Shop were left by Song Li, but he has not been able to get these three medicinal materials. From this we can see how difficult it is to obtain these three medicinal materials.

So if you want him to collect enough medicinal materials for him to refine three times, it may not be enough to give him another ten years, but if you use these medicinal materials in your hands that can only be refined once, the risk is too great.

"Forget it! Why do you think so much? If the refining fails, you can't find other pill recipes for pills or find these three medicinal materials in the future! After capturing Yin Zhenyu this time, I don't know how the people from the Demon King Palace will retaliate against me. I must break through to the Spirit Sea Realm as soon as possible, otherwise I might die in the hands of the Demon King Palace that day!"

After weighing the pros and cons in his mind, Song Li decided to use the existing medicinal materials in his hand to refine the marrow-cleaning bone refining pill.

When he captured Yin Zhenyu, in addition to two or three hundred human powerhouses, there were also some escaped demon generals in the valley. In this way, the fact that he captured Yin Zhenyu alive could not be concealed. With the vengeful personality of the Demon King Hall, he would definitely continue to send people to kill him next.

I believe that the next time the Demon King Palace sent him to assassinate him will never have a cultivation level below the seventh level of the Spirit Sea Realm. If he does not want to be killed by the Demon King Palace, he must break through to the Spirit Sea Realm as soon as possible.

Although there are certain risks in refining marrow-cleaning and bone refining pills with the existing medicinal materials in your hand, how could it be possible to improve your cultivation without taking any risks? Thinking of this, Song Li put away the jade slip in his hand, took out a hundred pieces of spiritual jade, arranged a formation to prevent the spread of breath, and directly sacrificed the Yin-Yang Star Gathering Furnace.

Bang!

Song Li raised his fingers upwards, and a dark flame suddenly appeared on Song Li's fingertips. Song Li bounced his fingers, and the dark flame shot into the Yin-Yang Star Gathering Furnace suspended in the air.

The terrifying temperature contained in the imperial fire instantly emanated from the Yin-Yang Star Gathering Furnace. If Song Li had not set up a formation to prevent the breath from leaking, he might have probably been healing the wounded in the cave with Song Li, the three Qingying and others who had to condense their protective true energy to continue to stay in the cave.

After calling out the Emperor Fire, Song Li did not rush to start refining the pills, but carefully recalled the steps recorded in the jade slip for refining the marrow-cleaning bone elixir.

Song Li had never been so careful when he refining elixirs before, but because the marrow-cleaning bone refining pills he refined this time was not only of higher quality than the elixirs he had refined in the past, but the medicinal materials in his hand were only enough for him to refine them once, so Song Li had to be careful.

After recalling the steps of refining the marrow-cleaning bone pill in my mind, and after confirming that there were no missing, Song Li took out the Nine-Leaf Fire Lotus from the storage bag.

Song Li suddenly waved his arm, and the Nine-Leaf Fire Lotus instantly flew into the Yin-Yang Star Gathering Furnace. The pitch-black Emperor Fire Lotus wrapped the Nine-Leaf Fire Lotus, and a hot breath came from the Nine-Leaf Fire Lotus. The Nine-Leaf Fire Lotus emitted a strong light, just like trying to resist the Emperor Fire in the Yin-Yang Star Gathering Furnace, firmly protecting the Nine-Leaf Fire Lotus from refining it.

As a saint from the fog, Song Li has refined very high-quality elixirs before, so Song Li knew that he should not be impatient if he wanted to refine the Nine-Leaf Fire Lotus. He needed to use the Emperor Fire to burn the strong light that protected the Nine-Leaf Fire Lotus first, and then he could refine the Nine-Leaf Fire Lotus and extract the essence of the Nine-Leaf Fire Lotus.

With his hands changing rapidly, Song Li made a spell, and the imperial fire, which seemed a little violent, instantly began to become softer.

However, although the Emperor Fire is not as violent as before under Song Li's control, it does not mean that the high temperature contained in the Emperor Fire has also decreased due to it.

It took nearly a stick of incense to refine the strong light that protected the Nine-Leaf Fire Lotus. Without the protection of the strong light, the Nine-Leaf Fire Lotus began to melt slowly under the burning of the Emperor Fire.

"Fortunately, I did not put the three medicinal materials, such as Nine-Leaf Fire Lotus, Three Heart Grass and Yin-Yang Body Forging Flowers, at the same time, otherwise just refining these three medicinal materials and extracting the essence in them would be enough for me!"

Seeing the Nine-Leaf Fire Lotus gradually turning into a drop of golden liquid under the burning of the Emperor Fire, Song Li let out a long breath and reached out to wipe the sweat from his forehead.

Although the process of refining the Nine-Leaf Fire Lotus is a bit troublesome, Song Li finally successfully extracted the essence from the Nine-Leaf Fire Lotus. Song Li waved his arm again and threw the Sanxin Grass into the Yin-Yang Star Gathering Furnace. According to the method of refining the Nine-Leaf Fire Lotus just now, the essence from the Sanxin Grass was also extracted.

After taking a pill to restore true qi, Song Li took action again and extracted the last main medicinal material, the essence from the Yin-Yang Body Forging Flower. Seeing that the essence from the three main medicinal materials had been extracted, Song Li breathed a sigh of relief and put all the remaining dozen ordinary medicinal materials into the Yin-Yang Star Gathering Furnace.

It took more than an hour for Song Li to complete the step of purifying all herbal medicines. After such a long time, if you were to refine ordinary elixirs, you should have successfully refined the elixirs at Song Li's speed.

However, Song Li had known for a long time that he should not be impatient to refine pills of marrow washing and bone refining, so after a short rest, he began to take action and start to merge the essence of the medicinal materials in the Yin-Yang Star Gathering Furnace.

Buzz! Buzz! Buzz!...

Song Li controlled the Yin-Yang Star Gathering Furnace and slowly merged the essence of the medicinal materials in the furnace together. At this time, there were buzzing sounds in the Yin-Yang Star Gathering Furnace. From the furnace hole of the Yin-Yang Star Gathering Furnace, you could see a colorful ball of light that was constantly flashing dazzling light in the alchemy furnace.

Feeling that the medicinal essences in the alchemy furnace were gradually fusion, Song Li calmed down and carefully controlled the Yin-Yang Star Gathering Furnace and Emperor Fire. This step of the medicinal essences fusion is a very critical step. If there is a slight mistake, the medicinal essences that have just been extracted in the alchemy furnace will be destroyed.
