I'm adding some immortality to my life, how should I respond?

After successfully renting the cave, the two moved in immediately. Su Bai looked at the surrounding environment, and the place was well maintained. Except for being a little expensive, there were no disadvantages, and each time it was rented, it would be rented for at least ten years. "It's a bit of a waste." Xu Changge didn't care when he heard Su Bai's words. "It's not a waste. If we don't find the spiritual medicine for foundation building, we can come back to live here after we go to the Zhenyi Secret Realm. This spirit gathering array can't be wasted." Xu Changge took a breath of enjoyment while speaking. Su Bai also took a breath. Although it's not a third-level spiritual vein, it's close to the third-level spiritual vein after all, and there is a spirit gathering array. In terms of spiritual energy, it is much stronger than Ebony Island. Su Bai didn't even want to go out to participate in the auction, but started practicing immediately. Xu Changge didn't care about the spiritual stones used to rent the cave. Compared with the opportunity to build the foundation, these spiritual stones are not even a drop in the ocean. "Want to go out for a walk?"

After Xu Changge looked around the cave, she was very satisfied and invited Su Bai to go out for a look.

Su Bai naturally agreed.

She was a country bumpkin, and it was her first time to come to such a cultivator city, so of course she wanted to broaden her horizons.

Otherwise, it would be a wasted trip.

After the two of them left the rented cave, they both wore a veil to hide their faces.

Xu Changge was quite familiar with Tianyun City.

With Su Bai in her arms, the two of them strolled around slowly.

At first, Su Bai was very interested in all places in Tianyun City. After getting familiar with it, she calmed down and started to do business.

Inquire about the news of foundation-building spiritual objects.

Xu Changge took Su Bai in and out of different spiritual medicine stores, which had cooperation with Tianyun City.

Generally, when there was news about foundation-building spiritual medicine at the auction, they would also tell them and spread it to the independent cultivators through the stores to stir up the heat and increase the price of foundation-building spiritual medicine.

While Xu Changge was talking to the owner of the pharmacy, Su Bai was not idle either.

She was buying pill recipes.

Although the Spiritual Medicine Store mainly sells spiritual medicines, they also have pill recipes for sale.

Su Bai's goal was very clear, which was the recipe for the Foundation Building Pill.

Over the years, countless casual cultivators have come to Tianyun City. Not only does everyone have a copy of the Foundation Building Pill recipe, but anyone who needs it can also buy it.

It's just that the recipe is easy to get, but the spiritual medicine is hard to find.

When Xu Changge finished talking to the store manager and came over.

Su Bai looked at the other person's expression, and could not see any joy or disappointment, it was very calm.

"Any news?"

Although he knew the result, Su Bai still asked.

Hearing Su Bai's concern, Xu Changge reached out and played with her hair, shaking her head slightly.

"It's just an ordinary spiritual medicine store, and it doesn't even have the auxiliary medicine for the Foundation Building Pill."

Xu Changge was used to it. After all, she had been preparing the Foundation Building Pill ten years ago.

In fact, apart from the main ingredients of the foundation-building pill, chalcedony, purple monkey flower, and heavenly spirit fruit, the only auxiliary medicines she lacked were black ice flower and illusion heart grass.

She was not disappointed if she couldn't find it here, she just came to collect information.

It was Su Bai.

"Sister Su, I saw you bought a pill recipe just now?"

Su Bai nodded without any hesitation.

"I bought the recipe for the foundation-building pill."

"Sister, I have it here, why do you want to buy it?"

Xu Changge was a little surprised. She had the recipe for the foundation-building pill, so why did Su Bai buy it?

Did she not want to trouble herself?

So Xu Changge said again:

"Just tell me the recipe, I won't show it to you."

Then Xu Changge didn't understand what Su Bai was thinking.

Su Bai just shook his head and didn't explain.

Later, Xu Changge took Su Bai to another pharmacy.

They also went to Wanbaolou, which was rumored to be a mysterious organization spanning multiple countries.

Not only are there a lot of goods, but the reputation is also good.

As soon as Su Bai entered, he was dazzled by the various items inside.

In this Wanbao Building, there are not only spiritual medicines and magic tools, but also various exercises for sale.

Then Su Bai bought another recipe for the foundation-building pill under Xu Changge's strange eyes.

Before, Su Bai would buy a recipe every time she went to a pharmacy.

Now, she bought it from Wanbao Building. She has at least 20 recipes for the foundation-building pill in her hand!

Although Su Bai has never explained.

But Xu Changge roughly guessed the purpose of Su Bai's doing so.

This made Xu Changge shake his head and sigh at Su Bai's caution.

Foundation building is a big deal.

You can't be careless.

Su Bai bought multiple recipes for the foundation-building pill to compare them from multiple sources.

Seeing that the recipes are roughly the same, he knew that there was no problem with the recipes he bought.

It's just that some auxiliary medicines will be slightly different.

However, as a first-class alchemist, Su Bai can also see that the effects of different auxiliary drugs are different.Almost.

They are basically related to removing blood stasis, promoting blood circulation, unblocking meridians and reducing fever.

Even if these auxiliary medicines are missing, if the efficacy of other auxiliary medicines is sufficient, they can be successfully refined.

And according to these pill recipes and Xu Changge's introduction.

Let Su Bai understand three methods of foundation building.

The first is the foundation building pill based on spiritual medicine. This method is the safest. You only need to buy spiritual medicine and then ask the alchemist to refine the foundation building pill.

The second is the foundation building pill based on monster pill.

This method is a bit difficult, after all, it requires at least the monster pill of the second-level monster.

That is the monster beast equivalent to the foundation-building cultivator.

How can ordinary casual cultivators have the ability to hunt and then take the monster pill.

Even if the foundation-building family wants to obtain the foundation-building pill for the younger generation, they rarely consider this path.

The monster mountain range is long and the environment inside is complex. The place where the second-level monster beast is located is already very dangerous for cultivators.

Even some second-level monsters do not live alone. If you encounter a group of second-level monsters, you will die miserably, and no one will help collect the bodies.

Therefore, this method is generally considered by some desperate people or cultivators who are extremely confident in their own strength.

The third method is to break through hard without using the foundation-building pill.

But this method is no different from committing suicide in Su Bai's opinion.

There are spiritual root restrictions for hard breakthrough.

If you have a high-quality spiritual root, you have a 50% success rate without relying on the foundation-building pill.

If you have an earth spiritual root, you can have a 90% success rate!

Even if the skills are more powerful, the probability is 100%!

Not to mention the heavenly spiritual root.

That kind of legendary existence, Su Bai's small place has never even heard of it.

Of these three foundation-building methods, Su Bai thinks that the most cost-effective is naturally the first one.

Buy spiritual medicine and then refine the foundation-building pill.

But this method has a difficulty.

Too many cultivators are competing for these foundation-building spiritual medicines.

The growth environment of auxiliary medicines does not require too much, so there is no shortage of them.

But the main medicine of the foundation-building pill not only has a harsh growth environment, but also has age requirements.

If you don't have spiritual medicine that is hundreds of years old, you will only get a furnace of useless pills if you refine it.

It's all pill poison. If you eat it, you will ascend to heaven on the spot, and you don't have to think about building a foundation.

Su Bai just hopes that he and Xu Changge will have better luck this time.
