I live forever in the world of cultivation.

Along the way, He Song had no accidents.

Soon, the escape light transformed by He Song left the jurisdiction of Yuheng Immortal City and returned to the jurisdiction of Tianquan Immortal City.

However, even after returning to the jurisdiction of Tianquan Immortal City and arriving on his own territory, He Song was still as cautious as before.

Although this place is the hinterland of Houtu Sect, we are not afraid of ten thousand, just in case.

It's better to be cautious.

Moreover, He Song was constantly adjusting his flight direction as he continued to fly forward.

On this return trip, he did not want to return directly to Tianquan Fairy City, but wanted to go to Lianshan Fairy City.

Lianshan Fairy City borders Tianquan Fairy City.

Not far or near from Tianquan Fairy City.

And it is also located in the hinterland of Houtu Sect, so safety is guaranteed.

He Song has just harvested a large amount of elixirs, which are the main ingredients for refining various elixirs.

But for things like refining elixirs, only the main medicine is not enough.

It is also necessary to add auxiliary drugs before it can be refined into an elixir.

Under such circumstances, He Song naturally needed to go to other places to buy auxiliary medicines for refining various elixirs.

Only when all the main medicines and auxiliary medicines are gathered together, can He Song start the alchemy furnace and try to refine the foundation-building elixir.

But if you buy the auxiliary medicine directly in Tianquan Fairy City, I am afraid it will arouse suspicion.

Therefore, He Songcai had no choice but to make this strategy. After harvesting the elixir, he went to Lianshan Fairy City to buy auxiliary medicine, and then returned to Tianquan Fairy City.

In this way, He Song will stay in the area under the jurisdiction of Yuheng Fairy City for a while when he goes to harvest the elixir.

At other times, you are in the hinterland of Houtu Sect, so your safety will naturally be guaranteed.

This is the safest way and also the safest way.

Although the journey was longer, He Song didn't care too much.

Keep going.

He Song quickly passed through the jurisdiction of Tianquan Immortal City and entered the jurisdiction of Lianshan Immortal City.

It's dozens of miles outside the Immortal City in Lianshan.

A ray of aqua blue light fell from the sky and soon fell into a valley.

After confirming that there was nothing unusual in Lianshan Fairy City in the valley dozens of miles away from Lianshan Fairy City.

He Song then put on a black robe and changed his appearance and figure.

He also suppressed his own breath until the late stage of Qi training.

Then Shi Shiran walked out of the valley and headed towards the mountainous fairy city dozens of miles away.

soon.

He Song then entered the city.

Purchasing auxiliary medicines does not cost too many spirit stones.

Even though He Song needs to refine more pills, they are also more complex.

But every time after He Song bought an auxiliary medicine, he would go to the inn, change his appearance and start buying again.

Therefore, when He Song continued to purchase various auxiliary medicines and shuttled between major shops, no one was keeping an eye on him.

Maybe someone is targeting him.

But He Song was very cautious. Every time he bought an auxiliary medicine, he would change his appearance to throw away those who were targeting him.

In this way, after He Song changed his appearance several times and bought all the auxiliary medicines he needed, he did not find anyone targeting him.

But even so.

After He Song purchased the last auxiliary medicine, he entered an inn and walked out after changing his appearance.

It wasn't that he was afraid of the Qi-training monks who were eyeing him.

It's just that he is cautious by nature, and he has developed this habit from a very early age.

Therefore, even if his cultivation has reached the middle stage of foundation building.

For some monks in the Qi training stage, they could kill them casually, but He Song was not arrogant.

Caution is the boat.

What if there is a foundation-building family standing behind those monks in the Qi training period?

What if the younger one is beaten and the older one comes?

just in case......

With this idea in mind, He Song was naturally cautious when going out.

After a makeover.

He Song left the Lianshan Fairy City.

After leaving Lianshan Fairy City dozens of miles away, He Song restored his cultivation aura to the middle stage of foundation building, and turned into a ray of aqua blue light, heading towards Tianquan Fairy City.

Soon, outside Tianquan Immortal City, a ray of light fell from the sky and fell directly into He Song's mansion.

When the light dissipated, He Song's figure also appeared.

Until he returned to Tianquan Immortal City and landed in his own mansion.

He Song breathed a sigh of relief, and a stone fell from his heart.

Fortunately.

This time when I left Tianquan Fairy City, I did not encounter any crisis or any minor incidents.

Moreover, he also harvested the elixirs he had planted ten years ago.

And purchased many auxiliary medicines for refining elixirs.

In this way, He Song's purpose of leaving Tianquan Fairy City this time has been achieved.

Next.

It's also time to start trying to refine the foundation-building elixir, so that your alchemy skills can start to improve by leaps and bounds.

With such thoughts flashing through his mind, He Song quickly stepped into his alchemy room.

In the alchemy room.

A high-grade magic weapon, an alchemy furnace, has been quietly placed in it.

This high-grade magic weapon, the alchemy furnace, was purchased by He Song a few years ago when he was trying to refine the first furnace of foundation-building elixir.

Its name is Lieyang Furnace.

The entire body is made of flame copper, which has excellent thermal conductivity and has many other wonderful uses.

This Fierce Sun Furnace cost He Song tens of thousands of spirit stones, which is very precious.

At that time, He Song, in order to try to refine the foundation-building elixir, was not stingy at all with the various things needed for the elixir.

The alchemy furnace is a high-grade magic weapon needed to refine the foundation-building elixir.

Refining various elixirs, auxiliary medicines, etc. required for the foundation-building elixir.

The environment required to refine the foundation-building elixir.

As well as everything else needed to refine the foundation-building elixir, they were all created by He Song.

The alchemy room he was in now was specially built by him for the purpose of refining the foundation-building elixir.

However, He Song's alchemy skills at that time were not as advanced as they are now.

Naturally, the alchemy room built was of little use after the failed attempt to refine the foundation-building elixir.

Normally when refining elixirs, one does not need those things specially arranged for refining foundation-building elixirs.

It can be said that if the things in this alchemy room are not used to refine foundation-building elixirs, a large part of them will not need to be used.

Only when trying to refine the foundation-building elixir can this alchemy room really come into use.

Like now.

Stepping into the alchemy room, He Song waved his hand, and several jade boxes suddenly appeared in front of his eyes.

When trying to refine the foundation-building elixir, it is natural to start with the simplest one.

Earth Spirit Pill.

It is made from the main medicine of Tu Ling Ginseng, supplemented by many other elixirs.

It can increase the cultivation level of Foundation Establishment monks.

Among them, the higher the earth attribute affinity, the more mana will be added after taking it.

He Song possesses the four spiritual roots of metal, wood, fire and earth, and his earth attribute spiritual roots also have the best affinity.

Therefore, after He Song established the foundation, he mainly took the earth spirit pill.

As for other monks with higher spiritual root affinity, the pills they take are naturally of another kind.

However, they do not have He Song's means to become alchemists, and now they are even ready to try to refine earth spirit pills.

As a foundation-building elixir for improving cultivation, the difficulty of refining the earth spirit pill is relatively low among the foundation-building pills.

He Song worked hard to study the first explanation of the alchemy method, and he also had an understanding of the difficulty of refining each elixir.

Naturally, when I learned that the refining difficulty of the Earth Spirit Pill was relatively low, and I already had its recipe.

It was natural to choose the Earth Spirit Pill as the breakthrough point.

Sitting in the alchemy room.

He Song looked focused.

However, various precautions for refining the earth spirit pill kept flashing through his mind.

At the same time, He Song selected the elixirs needed to refine the earth elixir one by one and placed them where he could easily get them.

After doing all this, He Song looked at the high-grade magic weapon alchemy furnace in front of him.

There was a glint in his eyes.

Next.

Just try to refine the earth spirit elixir.

Hope it works!

After cheering himself up in his heart, He Song waved his hand casually.

A spiritual fire suddenly ignited beneath the Fierce Sun Furnace, quickly burning the surrounding air.

At the same time, a hot breath also circulated on the Fierce Sun Furnace, and soon the entire alchemy furnace was burning red.

Even the entire alchemy room seemed to be on fire.

However, after seeing this scene, there was no trace of surprise on He Song's face. On the contrary, he was very calm.

The reason why the Burning Sun Furnace is called the Burning Sun Furnace is because once it is heated, it will turn red all over, just like the burning sun.

However, such discoloration is not because the melting point of the casting material is too low, but because of the particularity of the material.

This is what the blazing copper used to cast the blazing sun furnace is like.

Moreover, its color change will not reduce the quality of the elixir.

On the contrary, it will slightly increase the chance of becoming a pill.

Only when the whole body is red is when the Fierce Sun Furnace is truly effective.

The Fierce Sun Furnace had begun to take effect. He Song made a casual move, and the jade box on the side suddenly opened automatically and quietly without any wind.

Under the control of He Song's spiritual consciousness, each medicinal material fell into the Fierce Sun Furnace at the right time, just like a swallow returning to its nest.

As a burst of medicinal fragrance spread, He Song's expression remained unchanged, but there was a hint of solemnity in his eyes.

The elixir has been given.

The next step is to burn the impurities inside and fuse the pure medicinal liquid together when its medicinal effect is strongest.

When the medicinal liquids are truly fused together, and the effect of one plus one is greater than two, greatly increasing the efficacy of the medicine, then the technique of condensing pills can be supplemented.

When the elixir is condensed into an elixir in the elixir furnace and bursts out of the sky, it is the time when the elixir is completed.

However, the real difficulty in refining alchemy lies here.

It is actually not difficult to burn off the impurities and find the time when the medicinal effect is strongest.

The difficult thing is to fuse the medicinal liquid and stimulate the best medicinal power to greatly increase its efficacy.

This kind of thing requires the alchemist to have enough care, observation, and other qualities.

Only in this way can we seize this fleeting opportunity and perfectly refine a furnace of elixirs.

Without a very long period of practice, the success rate may be disastrous.
