There are four roads in this square, and at the end of each road there is a Zhenyuan Palace, and each Zhenyuan Hall has a different test.

Sun Shan and the other disciples of the medical hall pushed open the door of the Zhenyuan Palace, and they found that there were actually a lot of Dan furnaces in this room, and each Dan furnace had different Dan recipes and even pills.

And if they want to get these pills and pills, they want to refine such pills.

This may seem like the simplest and safest test, but it can also be life-threatening.

There is only one medicinal material needed to refine the pill in front of the alchemy furnace, and if the refining fails, they will be swallowed by the flames in this alchemy furnace.

"Ahh

A miserable scream resounded in the Zhenyuan Hall, causing the disciples of the other medical halls to feel a chill in their backs.

"Senior Brother Sun, Senior Brother Lin has failed."

Sun Shan looked at the man who was swallowed by the flames in the alchemy furnace, and said bitterly: "It's a pity, if Senior Brother Lin can refine this Liangu Dan, then he will definitely become a master of alchemy in the future!" ”

Even Gu Dan and they have seen its effect, the grade of this elixir is naturally in the elixir, but it is a rare elixir among the elixir.

It's just a pity that the disciples of this medical hall failed to pass this test and were directly swallowed by the flames in the alchemy furnace.

"Senior Brother Sun, if we leave here, we must refine one of these pills, otherwise we won't be able to get out of this room."

This is the rule of leaving this Zhenyuan Palace, if they want to leave here, then they need to refine one of the elixirs in these alchemy furnaces.

Sun Shan looked at these alchemy furnaces, and then said: "The alchemy furnaces in this room all correspond to one of the elixirs, and if you want to leave here, you want to refine a kind of elixir here, but it's just ......"

Sun Shan didn't say it explicitly, these elixirs were all very difficult to refine, and even Sun Shan was not half sure of refining one of them.

"Senior Brother Sun, it's better for you to go out in person."

Many of the disciples of the medical hall were a little afraid, after all, Senior Brother Lin had just died in front of their eyes.

Sun Shan couldn't shirk it, and said, "I'll try it." ”

If it was possible, of course Sun Shan didn't want to refine this elixir, after all, he could let other disciples refine it, and then snatch the formula of this elixir from their hands, wouldn't it be better?

However, these pills in the alchemy furnace only have one chance to be refined, if Sun Shan gave almost all of these to these disciples, then of course it would be good to succeed in the end, if not, Sun Shan would have to lose his life.

Sun Shan looked at all the alchemy furnaces in the entire room, and then selected an elixir called Huanglong Dan.

The medicinal effect of this Huanglong Pill is also very practical, that is, it can make people gain divine power, just like the power of the Yellow Dragon, it is really not uncommon for such a pill to increase strength, but this Huanglong Pill is naturally placed here for his reason.

Sun Shan said: "Although this Huanglong Pill is the one with the most herbs among these elixirs, it is the simplest and easiest pill to refine. ”

Sun Shan is worthy of being a disciple of Master Zhang, although he lost to Lin Xiaoyi, but he does have some opinions of his own on the way to this elixir, and he recognized this Huanglong Pill at a glance as the best refining among these elixirs.

"Senior brother, be careful."

Sun Shan sat down cross-legged, and then began to pick up the pills in front of the alchemy furnace, and then put them into the alchemy furnace one by one.

"It's really a good Dan furnace, it's even better than the purple gold tripod of the master!"

This alchemy furnace seems simple, but it is actually a spiritual treasure, if Sun Shan can really refine this Huanglong Pill, then he can get this spiritual treasure alchemy furnace.

Sun Shan put the herbs into this alchemy furnace and refined them one by one into medicinal powder.

This process seems complicated, but it is actually the simplest step, and after doing this, Sun Shan put these medicinal materials into the alchemy furnace.

"That's the most problematic fusion."

When Sun Shan fused the elixir, he was also a little worried, because this was the most problematic step in refining the elixir, if there was a problem in this step, then he would be swallowed up by the flames in this alchemy furnace just like the previous Senior Brother Lin.

Sun Shan used all his spiritual power to control the flames in this furnace, ensuring that he would not let the flames in this alchemy furnace destroy the elixir.

"Looking at Senior Brother Sun's operation, there should be no problem, right?"

Sun Shan also has a lot of prestige among these disciples, and it was only because of Lin Xiaoyi's appearance that Sun Shan lost some face.

But at this critical moment, only Sun Shan could take them out of this Zhenyuan Palace.

And just when everyone thought that Sun Shan was about to succeed, they didn't think that there was a strange sound in the Dan furnace.

"Listen, what is the sound coming from Senior Brother Sun's alchemy furnace?"

The disciples of the medical hall listened attentively, and there was indeed a strange sound coming from the alchemy furnace.

"It's a dragon!"

Hearing this, everyone finally determined that the sound coming from the alchemy furnace was the sound of the dragon's groan.

The disciple of the medical hall was overjoyed and said, "It is worthy of Senior Brother Sun, he has really refined this Yellow Dragon Pill!" ”

The reason why this Yellow Dragon Pill is named after this is because when this pill is turned into a pill, there will be a dragon's roar, as if there is really a dragon formed.

Sun Shan didn't have any joy, when the sound of the dragon's chant came out, he felt that his spiritual power was disturbed by the sound of the dragon's groan.

The dragon clan is born to know how to use coercion to deter, even if there are only a few drops of low-grade dragon blood grass in this elixir, but when the sound of the dragon's groan comes out, it still makes Sun Shan's control decrease.

"This can't be done, if this continues, this Yellow Dragon Pill will not be able to be refined!"

Sun Shan used all the spiritual power in his body to control the Yellow Dragon Pill in this alchemy furnace strongly, but this Yellow Dragon Pill was indeed magical, and it turned out to be a sign of opposing Sun Shan's spiritual power.

Sun Shan was ruthless, he bit the tip of his tongue, and then a mouthful of essence blood sprayed on this alchemy furnace, and finally suppressed the Huanglong Pill in the alchemy furnace.

After a long time, the sound of the dragon's groan coming from the alchemy furnace finally became weaker and weaker, and finally calmed down.

And at this time, a stream of danxiang came out of the alchemy furnace, and everyone's hanging hearts could finally be put down.

"Senior Brother Sun has succeeded!"

Sun Shan's whole person was a little depressed at this time, in order to refine this Yellow Dragon Pill, he did not hesitate to put his cultivation into a big drop, so that he could control this Yellow Dragon Pill.

Sun Shan got up from the ground, and then slapped the medicine tripod, and there was a golden pill flying out of the alchemy furnace, it was the Huanglong Pill!
