Immortality begins with equipping a worn-out talisman pen.

A few days later, after careful consideration, Li Mufeng finally rented a street-front shop in the inner city and named it Fuyuzhai.

The shop mainly sells first-tier low-grade and mid-grade talismans, and occasionally sells a few high-grade talismans as its prized possessions to attract customers.

As for all the affairs of the shop, large and small, they were all handled by Shen Yuan.

Time flies like water.

In the blink of an eye, half a year has passed.

On this day, Li Mufeng was in seclusion in Fuyuan Residence cultivating when he suddenly sensed something and slowly extended his divine sense into the courtyard.

The ground rippled slightly, like waves spreading across a calm lake.

A moment later, a furry little head popped out from the ground; it was the Niffler.

It also had a letter in its mouth and a finely crafted storage bag.

Upon seeing this, Li Mufeng couldn't help but smile.

This little guy's earth-遁术 (earth-遁术 is a term used to describe a technique or method of escaping through the earth) is becoming more and more exquisite. If my divine sense were not far superior to that of other cultivators of the same level, I might not have been able to detect its presence.

It's obvious without even guessing that this letter was most likely sent by Chen Jingyuan.

Li Mufeng opened the letter first.

The letter was filled with joy, and he first congratulated him on his further progress in the art of talismans.

"It is truly a great thing that you have broken through to the second-tier talisman master. This will give us more opportunities to interact in the future."

Chen Jingyuan had clearly put in a lot of effort regarding Li Mufeng's inquiries about his Foundation Establishment experience and the Foundation Establishment Elixir formula.

Not only did he record his own insights into jade slips and store them in his storage bag, but he also collected the foundation-building insights of other fellow disciples from Danxia Peak and sent them over in his storage bag as well.

In addition, there are two Foundation Building Pill recipes.

The letter mentioned that after thousands of years of development in the cultivation world, the Foundation Establishment Pill has long since spawned many different schools of thought.

There are orthodox pill formulas made primarily with the spiritual herbs of heaven and earth, as well as unorthodox methods that utilize the inner cores of demonic beasts; as for the demonic path, there are even evil techniques that use the essence, blood, and soul of cultivators to refine human pills, which are despised by the righteous path.

The two pill formulas sent by Chen Jingyuan included one of the most common orthodox Foundation Establishment Pills in the cultivation world today, which uses rare and precious materials as the main ingredients and has a mild medicinal effect. It is also the most commonly refined pill by the vast majority of second-level alchemists.

The other one is a secret method for building a demon core, passed down by an elder of Danxia Peak.

This method uses the inner core of a second-tier demon beast as the main ingredient. Its medicinal power is no different from that of an ordinary Foundation Establishment Pill, but its medicinal properties are extremely domineering.

Chen Jingyuan even added a special note next to it:

"If you do not have a body refinement level comparable to the late stage of Qi Refining, do not attempt this lightly."

Seeing this, Li Mufeng couldn't help but feel a warmth in his heart.

This time, Chen Jingyuan truly put in his best effort.

These foundation-building insights and pill formulas may not be priceless, but they are certainly not things that ordinary cultivators can easily access.

What's consumed more is personal relationships and time.

The Qingxuan Sect is hundreds of thousands of miles away from the Tianque Immortal City, and it would take half a year for a letter to travel back and forth.

Clearly, after receiving his letter, Chen Jingyuan immediately began to run around gathering information for him.

Of course, Li Mufeng understood as well.

Besides our long-standing friendship, there is another reason.

I have successfully drawn a second-tier talisman.

Even if he only barely managed to create a talisman, and the quality wasn't outstanding, it was enough to prove that it was only a matter of time before he became a second-tier talisman master.

A future Tier 2 Rune Master is someone anyone should befriend in advance.

Thinking of this, Li Mufeng silently kept this sentiment in his heart.

Then, he took out the two Foundation Establishment Pill formulas and began to study them carefully.

The two formulas require almost the same auxiliary ingredients, totaling thirty-six, most of which are rare and precious medicinal herbs that are over a hundred years old, such as Star Moon Grass, Dragon Pattern Vine, and century-old stalactites.

What truly distinguishes the two formulas is the main ingredient.

The orthodox Foundation Building Pill requires two second-tier main ingredients—Xuan Yuan Bao and Jade Marrow Lingzhi; while the Demon Core Foundation Building Method directly uses the inner core of a second-tier demon beast instead of the main ingredients.

After reading it, Li Mufeng finally breathed a sigh of relief.

Fortunately, most of the auxiliary ingredients in both formulas are interchangeable.

Otherwise, even with his current wealth and the earning power of a second-tier talisman master, he would likely struggle to prepare two completely different foundation-building materials at the same time.

Even so, Li Mufeng still faces considerable challenges.

Although the Foundation Establishment Pill formula has been obtained, the real difficulty has never been the formula, but the spiritual materials needed for refining the pill.

According to his understanding, the vast majority of the auxiliary ingredients in the two formulas are firmly controlled by major sects and aristocratic families, and rarely enter the market. Even when they do appear, they are often bought up at high prices as soon as they appear.

As for second-tier main medicines like Xuan Yuan Bao Shen and Yu Sui Ling Zhi, they are extremely rare and hard to come by.

There are only three ways to obtain these materials.

Firstly, there are large shops with sect backgrounds, where a small number of quotas occasionally flow out; secondly, there are top-tier auctions like Tianbaolou; and finally, there is the black market, which is a mixed bag.

While the black market offers the most opportunities, it is also the most dangerous.

Murder and robbery, counterfeit goods traps abound, and given Li Mufeng's consistently cautious nature, he naturally placed them as the last option.

However, having the prescription at least gave them a clear goal.

Li Mufeng quickly made a plan.

From now on, he will try his best to attend the monthly auctions held by Tianbao Tower, and take advantage of the ample time to collect all the spiritual materials needed for Foundation Establishment.

After clearing his mind, he finally focused his attention on the three jade slips in his storage bag.

A quick scan with his divine sense revealed a reaction in the equipment inventory.

[Equipment - Foundation Establishment Experience Jade Slip (Chen Surname Foundation Establishment)]

[Effect: After comprehension, the success rate of Foundation Establishment increases by 2%]

Upon seeing this line of information, Li Mufeng was startled.

Li Mufeng never imagined that he could increase his Foundation Establishment experience so simply and directly. Wouldn't that make his chances of achieving Foundation Establishment even greater?

It should be understood that for a cultivator with a mid-grade spiritual root, even with ample preparation, the chances of successfully establishing their foundation are slim without the aid of Foundation Establishment Pills.

A Foundation Building Pill of normal quality can usually increase the success rate by about 20%; if the quality reaches the premium level, the effect can even approach 30%.

Li Mufeng believed that he didn't have the luck or background to get a high-quality item, but at the very least he had to get a genuine one.

But now, the equipment slots can directly absorb the foundation-building insights of predecessors and turn them into a real success rate.

This means that as long as one continues to collect jade slips containing insights into Foundation Establishment, one's grasp of Foundation Establishment can gradually improve.

Thinking of this, a resolute look gradually appeared in Li Mufeng's eyes.

"If it's not a 100% chance of achieving Foundation Establishment, what's the difference between that and suicide!"

He quickly made up his mind that when collecting Foundation Establishment materials in the future, he would also collect Foundation Establishment experience jade slips.

With that thought in mind, he no longer hesitated and devoted all his attention to the experience jade slip.

A moment later, a massive amount of information entered his mind.

About three hours later, on the panel...

Foundation Establishment Success Rate +2%, Current Probability 2%

Li Mufeng didn't stop, and soon took out the next Foundation Establishment experience jade slip.
