A spiritual herb that refined the foundation-building pill was put into the reddish elixir furnace that had been burned by the ground fire, and it didn't take long to turn into a small pool of green spiritual liquid.

Then, when refining impurities, only the most essence of the spiritual herb is preserved.

after.

It is to melt one by one according to the order on the foundation-building pill recipe.

But.

As the alchemy steps progressed steadily, Gu Changsheng still discovered the difference between the foundation-building pill and the Qi training stage pill he had refined before.

Perhaps because the spiritual herbs that refine the foundation-building pill contain more spiritual energy, Gu Changsheng's more true energy was consumed during the smelting and refining process.

Generally speaking, because of the strong true qi, Gu Changsheng consumed only 50% of his true qi after refining a furnace of elixirs in the later stage of qi training.

But now, after just smelting and refining all the spiritual herbs of the Foundation Building Pill one by one, he has consumed 30% of his true energy, and this consumption is not small.

The elixir fusion and fire control are still a long time in the middle, which consumes true qi and mind.

But now that the alchemy has begun, there is no reason to give up halfway, so I can only continue to refine it.

One hour later.

After Gu Changsheng looked at the alchemy liquid in the alchemy furnace that had not yet shown signs of elixir condensation, he realized how reckless it was to try to refine the foundation-building pill.

He did not refine the elixirs in the later stage of Qi training for more than one stick of incense. Now it took more than an hour for the foundation-building pill to fuse from the elixir liquid to the elixir condensation, which Gu Changsheng did not expect.

More than half an hour passed.

When only 20% of the true qi was left in Gu Changsheng's body, the elixir liquid in the elixir furnace finally showed signs of elixir condensation.

Gu Changsheng did not delay and quickly drove the only two percent of the true qi in his body to use the alchemy technique.

"Puchi!" After a slight sound.

Immediately afterwards, a pungent and unpleasant white smoke came out of the alchemy furnace, instantly filling the small stone chamber.

Obviously, the alchemy failed this time.

Gu Changsheng was not surprised by the pungent smell and the white smoke. He used a small spell to absorb the white smoke into a small water ball the size of a fist, and then he looked at the residue in the alchemy furnace.

Since Gu Changsheng refining the alchemy, he failed hundreds or thousands of times, so he also figured out his own set of ways to check the reasons for the failure.

His method is to observe and analyze the elixir residues in the failed elixir furnace.

The same is true for the foundation-building pill that failed to refine this time.

While recalling all the details of the foundation-building pill just now, I observed the residue of the foundation-building pill in the elixir furnace.

It was found that among the many residue powders, several grains of rice-sized particles attracted Gu Changsheng's attention.

After careful observation and feeling, I found that these are all ingredients of the main medicine for refining the foundation-building pill.

Gu Changsheng knew that this was a manifestation of the fact that the main medicine for refining the foundation-building pill was not completely melted, or that it was not completely fused with other spiritual liquids.

Although there are specific procedures in the elixir recipe for Foundation Building Pills, they will not be copied completely when the elixir is refined, because the years of the spiritual herbs are refined, the size of the earth fire used will be slightly different when the spiritual herbs are melted.

The earth fire is smaller and may not be able to completely melt the old spiritual herbs.

When the earth fire is too big, the essence of the spiritual herb may be directly extracted.

so.

Past experience is very important for alchemy.

Gu Changsheng is not short of this. During the two and a half months in the alchemy workshop on Changqingdao, he has never helped to refine pills day and night. Not only has the alchemy skills improved by leaps and bounds, but his experience in refining various pills has also improved by leaps and bounds.

so.

After carefully checking the residue in the alchemy furnace, Gu Changsheng adjusted the direction of the next alchemy after discovering the existing problems.

However, before refining the next foundation-building pill, Gu Changsheng had to restore his true energy to his best state.

The ordinary spiritual energy absorbed in the spirit stone was somewhat inconsistent, so Gu Changsheng could only temporarily take some pills in the storage bag to restore cultivation.

Fortunately, he is an alchemist, and he has prepared a lot of such elixirs, at least enough for him to make alchemy.

......

After one stick of incense.

After Gu Changsheng completely restored his true energy and adjusted his mental state to the best, he began to open the furnace and refine the foundation-building pill for the second time.

Even though Gu Changsheng had confidence in his alchemy, he still successfully refined a foundation-building pill for six failures for various reasons.

At this time, a day and a night have passed outside.

Master Wang, who was guarding outside, was a little anxious.

Fortunately, no one discovered this stone chamber built underground, which made him feel a little relieved.

As for what Gu Changsheng did in the stone chamber, Master Wang didn’t know.

He guessed all the alchemy, weapon refining, qigong, etc., but there was no positive answer.

I thought the other party was just in seclusion and practiced for a few hours, but who would have thought that he would not come out after one day or one night.

If it weren't for the fear of angering Gu Changsheng, Master Wang would have wanted to forcefully open the stone door of the stone chamber where Gu Changsheng was.

Thinking that Gu Changsheng was his nobleman, and the powerful strength exposed by Gu Changsheng when he killed the two evil spirits of the Black Wind, Master Wang could only wait patiently.

......

Half a day later.

Gu Changsheng took advantage of the successful refining of the foundation-building pill and then refined the last three furnaces, which was very successful.

Not only did he obtain more than a dozen foundation-building pills, but his experience in refining foundation-building pills has been consolidated.

It can be said that it has gained a lot.

The key is.

Among the dozen foundation-building pills that were successfully refined, there is also a top-grade foundation-building pill with cloud patterns.

You should know that this top-grade foundation-building pill has an increased chance of 50% from the breakthrough foundation-building period, which is a more precious existence than the general foundation-building pill.

This foundation-building pill with cloud patterns was produced in the refining of the last furnace of foundation-building pills. When other successes were successful, it only refined one.

Gu Changsheng was also overjoyed. If he could have the help of ordinary foundation-building pills, he would be confident that he would break through the foundation-building period.

Now that we have the best foundation-building pill, it is almost certain to break through the foundation-building period.

It’s just that how to break through the foundation-building period when taking the top-quality foundation-building pill becomes a problem.

The true qi that Gu Changsheng cultivated is all yin-attribute true qi refined from corpse qi or yin evil energy. Therefore, when breaking through the foundation-building period, it is best to find an environment containing a large amount of corpse qi or yin evil energy.

Otherwise, when you break through the foundation building period, you need to absorb a large amount of corpse energy or Yin evil energy when you need to absorb it, which will bring unpredictable trouble to Gu Changsheng's breakthrough.

The problem is here.

Now Gu Changsheng is in the enclosed space of the undersea island, and there are only ten days left.

So it is difficult to find a place that matches the breakthrough.

But in order to break through the foundation-building period as soon as possible, Gu Changsheng still has to try his best.

then.

Gu Changsheng walked out a day and a half after entering the stone room.

"Master Wang, can you tell me where there is a strong yin aura on the island?" Gu Changsheng said first without waiting for the other party to speak.

actually.

Finding a place containing corpse energy is the most suitable situation for Gu Changsheng.

However, the underwater island where he is located has been covered with dust for a long time. Apart from hundreds of cultivators in the late stage of Qi training, there may be no other living creatures, so Gu Changsheng did not expect a place with rich corpse energy to appear.

If you kill hundreds of late-stage cultivators in Qi training just to break through your cultivation, Gu Changsheng would be unbearable.

Only then did we settle for the second best and chose to find a place with strong Yin and evil spirits.

Master Wang was also speechless. Gu Changsheng asked him to protect outside the stone chamber for a day and a half, and began to direct him to do things without even saying a word of thanks.

But now he is a man under the roof and has to bow his head.

"I can't guarantee it, but I can try it."

Although Master Wang was a little complaining, he was not vague at all.

Immediately afterwards, he took out his exquisite copper coins and threw them upwards, starting a new round of divination and calculation.

Master Wang said a while and then calculated his fingers before he said:

"I have to count it. There is really a place on this island that is in line with the rich and yin aura that Fellow Daoist said, but it is not in the center of the island, but in a valley five or six miles northwest of us."

When Gu Changsheng heard this, his eyes flashed.

This is exactly in line with Gu Changsheng's wishes. He can stay away from the central area of ​​the island and can reduce unnecessary trouble when he breaks through.

only.

Master Wang’s oil bottle has become another big problem.
