Time passed day after day.

As Mu Ganxin expected, three days later, all the auxiliary medicinal materials were successfully refined.

Of course, there were two or three failures along the way.

However, the medicinal materials of the heaven-level elixir itself are extremely difficult to refine, and it is already quite powerful to have this success rate.

Subsequently, Mu Ganxin put all the medicinal liquids of the auxiliary medicinal materials in the bottles that had been prepared long ago.

After a short rest, when the spiritual power in his body had almost recovered, Mu Ganxin entered the state of refining again.

After the auxiliary medicinal materials are refined, the next step is naturally the refining of the main medicinal materials.

There are three main types of medicinal herbs.

They are: Millennial Soul Liquid, Tong Flexible Bone, and Ninth Order Emperor Beast Core.

For these three medicinal materials, Mu Ganxin's face was extremely solemn.

There is nothing about the failure of auxiliary medicinal herbs, after all, there are alternative medicinal herbs to replace.

But these three herbs are different.

Because, it is all unique.

Fail, and there will be none.

It will have to take a long time to find it again.

This situation is obviously not what Mu Gan wants to see.

He didn't have so much time to search for medicinal herbs all over the world.

Moreover, he couldn't wait that long.

Liu Bingxuan, who is in the state of soul body, must be very lonely, this loneliness, he has endured for thousands of years.

He didn't want Liu Bingxuan to bear it.

So, this time, he had to do it right the first time!

"!!"

With a low roar, the pressure was released, and then Mu Ganxin released the flames.

"Whoosh-"

Then, along the two furnace holes, it was drilled into the medicine furnace.

It wasn't until the temperature reached almost 1,000 degrees that Mu Gan's eyes fell on the incomparably black droplet.

This drop is the thousand-year-old soul liquid.

According to legend, this drop of liquid was condensed after thousands of years of souls squeezing each other.

Within, there are countless resentful spirits.

And what Mu Ganxin has to do is to remove all the resentful spirits in this thousand-year-old soul liquid.

Make it incredibly pure.

Only in this way can it be suitable for refining the 'Soul Revival Elixir'.

As long as there is a little bit of resentment in the thousand-year-old soul liquid, it will lead to the failure of the Soul Rejuvenation Pill.

This is one of the reasons why shepherds are so cautious.

"Go. ”

With a wave of Mu Gan's hand, the drop of the thousand-year-old soul liquid that was extremely black and full of resentful spirits immediately came out of his hand and fell into the red medicine furnace.

"Zizi-"

As soon as the thousand-year-old soul liquid entered the medicine furnace, there was a burst of crackling sounds.

The thousand-year-old soul liquid is a liquid, and when it encounters flames, it will naturally make this sound.

But.

To the surprise of Demu's willingness.

The sound was loud enough, but on its own, it didn't change at all.

"Thousands of degrees of flame temperature, isn't enough?

Thinking so in his heart, he immediately raised the temperature of the flame again.

In the blink of an eye, it reached a terrifying 2,000 degrees.

In the face of the high temperature of 2,000 degrees, the heat emitted by the entire medicine furnace was quite terrifying.

Even Mu Ganxin himself was sweating profusely in an instant.

But.

Fortunately, his back was against the rockery, and in the rockery, the cold air that was constantly emitted made him feel a lot better.

"Sure enough, it is the holy land of refining, this time, I must not fail!"

Mu Ganxin nodded secretly, his eyes looking at the medicine furnace in front of him intently.

The entire medicine furnace was already quite terrifyingly red, but fortunately, his soul power was strong enough, otherwise, he would definitely not be able to see through the thousand-year-old soul liquid inside.

As the temperature rises, the thousand-year-old soul fluid finally has some changes.

Although this change is extremely small, it does exist.

"In less than two days, this thousand-year-old soul liquid can't be purified. ”

After observing it again for a while, Mu Ganxin said secretly in his heart.

The terrifying thing about the heaven-level elixir is that here, it takes an extremely long time just to refine the medicinal materials.

If you don't have enough concentration, you can't help it for a long time.

After making sure that there would be no problems, Mu Ganxin closed his eyes.

The medicinal materials for refining the heaven-grade elixir were extremely terrifying for his consumption.

He had to refine and reply at the same time.

Otherwise, exhaustion will occur.

As the thousand-year-old soul liquid continued to be scorched by the high-temperature flames, the resentful spirits inside suddenly let out a wailing sound.

This kind of voice is quite miserable.

Even in the voice, there is extreme unwillingness.

However, Mu Ganxin has never opened his eyes.

Two days passed, and the thousand-year-old soul liquid was successfully purified under this situation.

It turned into a drop of immensely pure liquid.

"Next, it's the turn of the bone. ”

After a short rest, Mu Ganxin's gaze fell on a crystal clear bone.

This bone is the flexible bone.

If you look closely, you can clearly perceive that this bone has a faint strong vitality.

It's like being alive.

Without too much hesitation, Mu Gan directly threw it into the medicine furnace and began to refine.

The sign of successful refining is to turn the flexible bones into liquid medicine like auxiliary medicinal materials.

This difficulty is more than two or three times higher than that of the thousand-year-old soul liquid.

After all, the thousand-year-old soul liquid is only to eliminate the resentful spirits in the liquid.

In the case of living ossified fluid, this is a process of solidifying liquid.

It's also one of the hardest processes.

However, no matter how difficult it is, the shepherd willingly will not run away from it.

"Zizi-"

Inside the medicine furnace, there was a constant sound.

Under the high temperature of more than 2,000 degrees, Mu was willing to warm up again.

In the blink of an eye, it was close to 3,000 degrees.

Although it is more difficult to refine the flexible bone, compared to the thousand-year soul liquid, the operation is obviously much easier.

There is no need to have too many scruples.

Just burn it.

After three days, the flexible bone finally turned into a drop of incomparably pure white liquid.

"The last herb has been refined. ”

Seeing that there was only one ninth-order emperor beast core left, Mu Ganxin breathed a sigh of relief.

Although the ninth-order emperor beast core was also quite precious, it was not impossible to find it.

With his strength, coupled with Xiao Jiu's strength, it was quite easy to kill a ninth-order imperial beast.

However, Mu Ganxin still hopes that it can be refined successfully in one go.

After all.

He was not willing to spend this time any longer.

"Come on. ”

With a light snort, Mu Ganxin entered the refining state again.

After refining for more than half a month, he was a little numb.

Fortunately, his mind and mind were strong enough, otherwise he would have lost his way long ago.

(The fourth update was finally written, and it took two hours...... It's not easy, ask for tickets, four more guarantees every day!!)
