Flying all the way, He Song can be regarded as thrilling and dangerous.

Soon, He Song's retreat left the jurisdiction of Yuheng Immortal City and returned to the jurisdiction of Tianquan Immortal City.

However, even if he returned to the jurisdiction of Tianquan Immortal City and arrived at his own territory, He Song was still as cautious as before.

Although this place is the hinterland of the Houtu Sect, it is not afraid of 10,000, just in case.

It's better to be cautious.

Moreover, in the process of constantly flying forward, He Song is also constantly adjusting his flight direction.

On this return trip, he didn't want to go back to Tianquan Immortal City directly, but wanted to go to Lianshan Immortal City.

Lianshan Immortal City borders Tianquan Immortal City.

It is not far from Tianquan Immortal City.

And it is also in the hinterland of the Houtu Sect, and its safety is guaranteed.

He Song had just harvested a large number of elixirs now, and these elixirs were the main medicines for refining various elixirs.

But for such a thing as alchemy, only the main medicine is not enough.

It is also necessary to add auxiliary drugs before it can be refined into a pill.

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

Only by getting together all the main drugs and auxiliary medicines can He Song open the furnace for alchemy and try to refine the foundation building elixir.

However, if you buy auxiliary medicine directly in the Heavenly Power Immortal City, I am afraid it will arouse suspicion.

Therefore, He Song had to make this decision, after harvesting the elixir, he went to Lianshan Immortal City to buy auxiliary medicine, and then returned to Tianquan Immortal City.

In this way, in addition to going to harvest the elixir, He Song would stay in the area under the jurisdiction of Yuheng Immortal City for a while.

The rest of the time is in the hinterland of the Houtu Sect, and the safety will naturally be guaranteed.

It's the safest road, and it's the safest one.

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

All the way forward.

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

Dozens of miles outside the mountain immortal city.

An aqua blue light fell from the sky and soon fell into a valley.

In the valley dozens of miles away from Lianshan Immortal City, after confirming that there was nothing abnormal in Lianshan Immortal City.

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

He suppressed his own breath to the late stage of qi training.

Only then did Shi Shiran walk out of the valley and head towards Lianshan Immortal City, which was dozens of miles away.

Soon.

He Song entered the city.

It doesn't cost too many spirit stones to buy auxiliary medicines.

Even if He Song needed to refine more pills, it was more miscellaneous.

But every time He Song bought an adjuvant medicine, he would go to the inn and set off to buy it again after a makeover.

Therefore, when He Song continued to purchase various auxiliary drugs and constantly shuttled among the major shops, no one was eyeing him.

Maybe there are eyes on him.

But He Song is very cautious, and every time he buys an adjuvant drug, he will change his appearance and throw away the people who are eyeing him.

In this way, after He Song changed his appearance several times and bought all the excipients he needed, he didn't find anyone eyeing him.

But even so.

After He Song bought the last excipient, he still entered an inn and walked out of it after a makeover.

It's not that he's afraid of those Qi cultivation cultivators who are eyeing him.

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

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

For some Qi cultivation period cultivators, it is even easier to take their lives, but He Song is not arrogant.

Be careful to sail the ship of ten thousand years.

What if those Qi cultivation monks were standing behind a foundation building family?

What if you hit the small one and the old one comes?

in case of

With such thoughts, He Song was naturally cautious when he went out.

After a makeover.

He Song left the Lianshan Immortal City.

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

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

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

Until he returned to the Heavenly Power Immortal City and landed in his mansion.

He Song breathed a sigh of relief, and a stone in his heart also fell to the ground.

OK.

Leaving Tianquan Immortal City this time, he did not encounter any crisis, and there were no minor episodes.

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

And purchased many auxiliary medicines for refining pills.

In this way, He Song's purpose of leaving Tianquan Immortal City this time was all achieved.

Next.

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

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

Inside the alchemy room.

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

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

It is called the Burning Sun Furnace.

Cast from flaming copper, it conducts heat very well and has many other wonderful uses.

This Burning Sun Furnace cost He Song tens of thousands of spirit stones, which can be described as very precious.

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

The high-grade magic weapon alchemy furnace required to refine the foundation building elixir.

All kinds of elixirs, auxiliary medicines, and so on needed to refine the foundation building elixir.

The environment required to refine the foundation building elixir.

As well as all the other things needed to refine the foundation building elixir, all of them were created by He Song.

The alchemy room where he is now was specially built by him and set up for refining the foundation building elixir.

However, at that time, He Song's alchemy was not as advanced as it is now.

The alchemy room that was built was naturally no longer of much use after the failure of that attempt to refine the foundation building elixir.

In ordinary times of alchemy, there is no need for those things that are specially arranged for refining the foundation building elixir.

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

It was only when he tried to refine the foundation building elixir that this alchemy room really came into use.

Just like now.

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

Trying to refine the foundation building elixir is naturally starting with the easiest.

Earth Elixir.

It is made of earth ginseng as the main medicine, supplemented by many other spiritual medicines.

It can increase the cultivation of the Foundation Realm monks.

Among them, the higher the affinity of the earth attribute, the more mana will increase after taking it.

He Song has four spiritual roots of gold, wood, fire and earth, and the affinity of his earth attribute spiritual roots is also the best.

Therefore, after He Song built the foundation, the pill he took was mainly the Earth Spirit Pill.

As for those other cultivators with a higher affinity for spiritual roots, the pills they took were naturally different.

It's just that they don't have He Song's means to become alchemists, and now they are ready to try refining the Earth Spirit Pill.

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

He Song worked hard to study the first solution of the Dan Dao, and he also had an understanding of the difficulty of refining each pill.

Naturally, when he learned that the difficulty of refining the Earth Spirit Pill was relatively low, and he already had its own pill formula.

Choosing the Earth Spirit Pill as the breakthrough point is naturally logical.

Sit upright in the alchemy room.

He Song's face was focused.

However, all kinds of precautions for refining the Earth Spirit Pill kept flashing in his mind.

At the same time, there were elixirs needed to refine the Earth Spirit Pill, which He Song also selected one by one and put them in the place where he could get them the most.

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

There was a gleam in his eyes.

Next.

It's an attempt to refine the Earth Spirit Pill.

Hope it succeeds!

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

A spiritual fire suddenly ignited under the Sun Furnace, scorching the surrounding air and quickly heating it up.

At the same time, a scorching aura also circulated above the Burning Sun Furnace, and soon the entire Alchemy Furnace was scorched red.

Even the entire alchemy room was reflected as if it was on fire.

However, after seeing this scene, He Song did not show a trace of surprise on his 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 the body, just like the burning sun.

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

This is the case with the flaming copper used to forge the Sun Furnace.

Moreover, its color change does not detract from 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, like today, is when the Burning Sun Furnace really comes into play.

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

Under the manipulation of He Song's divine sense, all kinds of medicinal materials also fell into the Sun Furnace at the right time, just like the milk swallow returning to its nest.

With a burst of medicinal incense coming out, He Song's expression remained unchanged, but there was already a trace of solemnity in his eyes.

The elixir has been placed.

Next, the impurities within it are cauterized, and when the medicinal effect is at its strongest, the pure liquid is fused together.

Wait until the liquid medicine is really fused together, and the effect of one plus one is greater than two, so that the medicinal effect is greatly increased, and then supplemented with the technique of condensing pills.

When the pill is condensed into the pill in the pill furnace and breaks out of the air, it is the time to become a pill.

However, the real difficulty of alchemy is also here.

It is not difficult to burn impurities in front of you and find the time when their medicinal effects are the most intense.

The difficulty is to fuse the liquid medicine 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 the opportunity in this fleeting opportunity to perfectly refine a furnace of elixir.

If you don't practice for a long time, I'm afraid the success rate will be miserable.
