Immortal cultivation starts with copying.

After a while, an elderly cultivator in his sixties who was at the foundation-building stage walked into the secret room.

"My dear friend, I heard that you want to exchange for the Foundation Establishment Pill?"

"I have a five-hundred-year-old spiritual medicine here, and I want to exchange it for your foundation-building pill."

Chen Yunhao nodded. This was his purpose and there was nothing to hide.

He doesn't have to worry about anyone stealing his elixir here, as the Medicine King Pavilion is not so despicable.

After Chen Yunhao finished speaking, he slapped the storage bag at his waist and took out the jade box containing the elixir.

"The jingji grass is old enough, but it's just a supplementary herb. It can only be exchanged for a low-grade foundation-building pill. My friend, do you want to exchange it..."

Of course, foundation-building pills are divided into four types: high-quality, medium-quality, low-quality and top-quality. At the auction of the Five Elements Sect, the foundation-building pills that appeared were all medium-quality.

If what Chen Yunhao brought today was the main ingredient of the Foundation Establishment Pill, at least he could exchange it for a mid-grade Foundation Establishment Pill.

In fact, it is not necessary to use spiritual medicine that is more than 500 years old to refine low-grade foundation-building pills. Any foundation-building pill refined with spiritual medicine that is 500 years old can almost reach the level of high quality.

Besides, these five hundred year old elixirs are not only used in refining foundation-building pills, but are also used in many other elixirs.

Although it was a low-grade foundation-building pill with much weaker medicinal power, it was enough for Chen Yunhao to break through given his dual spiritual roots.

"Change……."

Chen Yunhao nodded and agreed without hesitation.

Even a low-grade foundation-building pill is still in short supply in this market, and some can cost tens of thousands or even twenty thousand low-grade spirit stones.

For cultivators who are not born with good spiritual roots, such as four or five spiritual roots, if they want to break through the foundation-building stage, the foundation-building pill is an indispensable part, and it is best to use a high-quality foundation-building pill.

For cultivators with natural spiritual roots and dual spiritual roots, the lower quality ones are enough and are just an introduction at most.

The old monk threw a jade bottle to Chen Yunhao, which contained a low-grade foundation-building pill.

Chen Yunhao saw what the Foundation Establishment Pill looked like at the Five Elements Sect's auction, and he wouldn't make a mistake.

He poured the Foundation Establishment Pill from the jade bottle into his palm and examined it carefully. From its color, smell and medicinal power, it was undoubtedly the Foundation Establishment Pill.

As soon as the transaction was completed, the old monk left alone.

The young monk who brought Chen Yunhao here had been waiting outside the door.

Chen Yunhao followed the young monk into the hall of the Medicine King Pavilion again.

He already had the foundation-building pill, but Zhen Yunhao still wanted to buy some pills for daily practice.

He had taken a lot of Xiao Peiyuan Pills before, and he wanted to see if there was any elixir with similar medicinal properties.

"Do you have any elixirs for sale at Yaowang Pavilion that are similar in potency to the Xiao Peiyuan Pill?"

"There are two types: Qi Condensation Pills and Great Spirit Pills. Which one do you want, sir?"

Chen Yunhao had never heard of the Qi Condensation Pill, but he knew about another tonic pill.

This is an advanced elixir of the Bu Ling Dan. To put it simply, it is another elixir made by an alchemist by modifying the recipe of the Bu Ling Dan.

The effect of this great tonic elixir is similar to that of the small nourishing elixir, and it is considered one of the special elixirs of the Medicine King Pavilion.

As for the Qi Condensation Pill, I think even if it is not well-known, its effect should be almost the same as that of the Great Tonic Pill.

Chen Yunhao asked about the price. The price of these two elixirs was the same, thirty low-grade spirit stones per pill.

It is true that the price is a bit higher than that of ordinary stores, but when Chen Yunhao saw the elixir, he could understand it.

As expected of a professional alchemy sect, the quality is impeccable and well worth the price!

"I need one hundred Qi Condensing Pills and one hundred Great Tonifying Spirit Pills each. Do you have any Heart Purifying Pills? I'd like to buy two sticks of Tranquilizing Incense!"

"This customer is very lucky. A batch of Qingxin Pills were just delivered to us yesterday. We should have two or three left now..."

The young monk from Yaowang Pavilion replied with a smile on his face.

These young cultivators in Yaowang Valley have no background in the sect and are disciples with relatively poor qualifications.

After serving in the Medicine King Pavilion for a full year, you can return to the Medicine King Valley.

Of course, they are not on duty in vain. They all have points. The more they sell, the more points they accumulate. When they return to Medicine King Valley, they can exchange them for the resources they need for cultivation.

"Are there two or three left? Then I'll take them all..."

Qingxin Pills are not always available for purchase in Yaowang Pavilion; it depends on one's luck.

Moreover, what can be bought in the Medicine King Pavilion are only low-grade Qingxin Pills. The Medicine King Valley does not sell Qingxin Pills of medium grade and above to the public.

A pill of Qingxin Pill is worth one hundred and fifty low-grade spirit stones. A stick of Jingxin Incense can be used for three days, and each stick is worth three hundred low-grade spirit stones.

Adding all these items together, Chen Yunhao spent about seven thousand.

Fortunately, I sold some magic weapons along the way, and I emptied my storage bag immediately.

Walking from the North City to the South City, Chen Yunhao sold some of his most valuable magic weapons and received more than 20,000 low-grade spirit stones in return.

When Chen Yunhao walked to a crossroads near the south city, he saw a group of monks gathered by a wall at the crossroads.

In Chen Yunhao's impression, most monks like to be alone. Although there are some who travel in groups, they are basically brothers from the same sect.

At this intersection, dozens of monks were crowded together, whispering to each other. Not to mention Chen Yunhao, all other monks passing by were attracted over.

Chen Yunhao took two quick steps, squeezed into the crowd, and looked forward.

It turned out that there was a notice posted on the wall, which was issued by the Five Elements Sect.

Recruit a large number of cultivators in the Qi Refining and Foundation Establishment stages and go to Zhenhuang City.

Zhenhuang City is also a force under the Five Elements Sect, just like Lingyu City.

However, Zhenhuang City is located on the border of the wild area of ​​Beiyuan Road. It guards the wild area and monitors the monsters in the wild area.

There are six cities like Zhenhuang City around the wilderness area, belonging to the six major forces on the Beiyuan Continent.

The wild area is vast and boundless, occupying 40% of the area of ​​the Northern Yuan Continent.

It can be said that most of the Beiyuan Continent is the world of human cultivators, and a small part is the world of demons.

Every hundred years, a beast tide will appear in the wild area, and this has happened countless times since ten thousand years ago.

Even though Chen Yunhao had never seen a beast tide, he had long known from various channels that every hundred years there would be a beast tide that would sweep across half of the continent.

After experiencing countless beast tides, both human cultivators and demons actually understand what is going on.

No matter how big the Beiyuan Continent is, it has boundaries. There are limited resources for cultivation. The human race needs them, and the demon race naturally needs them as well.

In addition, the demon race and the human race are the two fastest reproducing races, so the resources for cultivation are even more scarce.

To put it bluntly, every beast tide is a planned cleansing operation.

Every beast tide will wipe out millions of monsters and hundreds of thousands of cultivators.

There would be no high-level demons or cultivators above the Nascent Soul stage in every beast tide, as if both sides had already discussed it.

Those fighting in the front are almost all cultivators in the Qi Refining and Foundation Establishment stages. To put it bluntly, they are just cannon fodder.
