Chapter 539 Refining the Life-Extending Golden Pill

It is important to understand that birth, aging, sickness, and death are the natural cycle of the universe, which is beyond human control.

Su Yi maintained his lifespan to 180 years old through cultivation and elixirs, living through three cycles of sixty years, which is an extremely rare skill.

Cao Erdan said he could extend his life, but he was somewhat skeptical.

After all, Cao Erdan is only a twenty-year-old kid.

Cao Erdan said, "I once passed through the Shennong Secret Realm, where there is a legendary prescription called the Longevity Prescription. With this prescription, one can refine the Longevity Pill, thereby regenerating the body's functions and preventing aging!"

Su Yi's eyes lit up, but he immediately shook his head: "This is just a legend, isn't it? Has anyone actually managed to get their hands on this formula?"

Cao Erdan shook his head: "Not for now, but as long as we have this prescription, there is hope. So General Su, you don't need to rush to give me your power. I can help you prolong your life. Give me some time, and perhaps we can find this prescription!"

Even without the formula for immortality, Cao Erdan could still refine elixirs to prolong Su Yi's life for a period of time.

When Cao Erdan took out the Shennong Cauldron and the rare and precious materials in his storage ring, Su Yi was amazed.

Who would have thought this young man was also a master alchemist!

Cao Erdan asked Su Yi if the Imperial Family had any rare and precious medicinal herbs that they could use.

Su Yi led Cao Erdan to his underground warehouse.

Su Yi was able to live to be 180 years old not only because of his abundant internal energy, but also because of the help of some elixirs.

However, he did not have the Shennong Cauldron, nor the Six Ding Divine Fire, nor Cao Erdan's miraculous medical skills, so naturally the purity of the pills he refined was much lower.

When the warehouse door was opened, Cao Erdan was also surprised.

Su Yi's warehouse actually contained quite a few rare and precious materials.

Among them are not only dozens of wild ginseng and lingzhi mushrooms, but also rare ironwood leaves and nine-tailed dragon sunflower flowers.

Cao Erdan nodded and said, "Using your rare and precious materials, along with the living coral in my hand, we can indeed refine Qi-replenishing pills. However, to refine life-extending elixirs, we are still missing one ingredient."

Su Yi hurriedly asked, "What kind of medicinal ingredient?"

"We need to find ten virgin boys and girls."

Upon hearing Cao Erdan's words, Su Yi waved his hands repeatedly: "As a general who protects the country, I can bring benefits to the people, but how can I do something immoral that goes against the natural order for my own benefit! Absolutely not!"

The stubborn old man's angry expression amused Cao Erdan.

However, Cao Erdan also felt that Su Yi was even more admirable.

As someone in a high position of power, how many people would sacrifice the lives of others to preserve their own status, let alone their own lifespan?

Cao Erdan quickly explained, "General, I didn't mean using the lives of young boys and girls to refine elixirs. I just need to extract hematopoietic stem cells from them; it won't harm their lives!"

Next, Cao Erdan explained to the old general how to extract stem cells.

Stem cell extraction surgery is a minimally invasive procedure with a relatively quick recovery, so there is no need to worry too much.

Extracting hematopoietic stem cells may lead to a decrease in the body's immunity, but there is generally no risk as long as the donor is a healthy person.

Only after hearing this did Su Yi agree.

This task was entrusted to Liao Kai, who found everything in less than three days.

For the past few days, Cao Erdan has been staying with the old man, Su Yi.

They could be said to eat and sleep together.

Every day after they woke up, the two of them would talk about everything.

Although Cao Erdan excelled in medicine, the old man was a learned man with extensive knowledge, which Cao Erdan greatly admired.

During this time, Su Yi also shared his understanding of the Dragon Clan with Cao Erdan.

When Su Yi's master was alive, he talked about the Dragon Clan.

Long ago, there was a continent in the East Sea called Tian Tan Continent, inhabited by a race called the Dragon Clan. Their leader was known as the Dragon God.

Later, for reasons unknown, the dragon race fell into internal strife, a great war that lasted for ten years, leading to the decline of the dragon race to the point that no one ever heard of any descendants of the dragon race remaining.

Now, almost no one knows that there is a continent called Tiantan, let alone the existence of the Dragon Clan.

If Su Yi's master hadn't been a renowned scholar of history, he wouldn't have known so much.

Hearing this didn't offer Cao Erdan much help in understanding his own background.

It also didn't mention that Huang Benchu ​​claimed to be the reincarnation of the Dragon God.

Three days later, the stem cell precursors were gathered.

Cao Erdan began using rare and precious materials to refine pills at Su Yi's house.

This time, the elixir was refined even more meticulously, requiring more than three days of gentle simmering.

After the elixir was put into the furnace, Cao Erdan would continue to spar with the old man whenever he had free time.

It was supposed to be a friendly exchange, but in reality, Su Yi was teaching Cao Erdan.

Based on this Heavenly Realm expert's more than 100 years of cultivation and combat experience, Cao Erdan has indeed met a good teacher!

Cao Erdan gains a lot from every conversation with Su Yi!

However, it was tough on the nanny.

Every time the two sparred, they left a mess that was impossible to clean up, so she had to call workers to come and fix it.

In six days, the two almost demolished the general's mansion.

Finally, the yard was full of construction workers, and the two of them squatted in the basement to continue their conversation.

This pair of friends, despite their age difference, truly felt like they had known each other for a long time.

The way out was through the elixir; there were a total of thirty small red pills.

Cao Erdan called it the "Life-Extending Pill".

If Su Yi takes one pill every day, it should extend his life by two or three years!

However, if one wants to live even longer, one needs to find the elixir of immortality.

Looking at Cao Erdan's pills, Su Yi couldn't help but feel deeply moved.

"Brother Cao, you are a rare and divine doctor in the world. Is there any longevity formula that is more effective than your life-extending pill?"

Cao Erdan had never seen the real formula for immortality, so he couldn't give a proper answer.

He simply said, "Perhaps it's a recipe left behind by the gods!"

Looking at Su Yi, he asked, "General, I know that when Taoists cultivate to a certain level, they can shed their mortal bodies and walk on the wind. Does that mean they become immortals? Or are there really immortals in the heavens, like those in Journey to the West?"

Su Yi couldn't help but smile.

In fact, almost every child, or rather, almost everyone, has asked this question.

Are there ghosts in the world? Are there gods in the world?

Su Yi said, "No one has ever seen a real immortal, but there must be cultivation techniques that allow one to surpass ordinary people."

What you mean by "flying on the wind" is actually about mastering the art of lightness to the extreme, to the point where you can make your body as light as a feather.

Moreover, there is an even more advanced technique than the lightness skill of leaping and bounding, which is the mental movement of the sky!

When a person's skill is cultivated to its peak, that is, when they transcend the Heavenly Realm, they can control everything with their will.

You've heard of flying on a sword, right? That's a type of sword control using mental power.

Upon hearing this, Cao Erdan hurriedly asked, "General, do you know how?"

Su Yi glared, and the wine glass in front of him flew up.

It flew higher and higher, and then, with a "crack," it shattered.

Cao Erdan couldn't help but clap his hands in praise.

Remembering how Su Yi had made his move earlier, he simply waved his hand, and the sword flew directly out of his house—wasn't that mind control?

Only then did he realize that Su Yi's physical confrontation with him was merely a way of guiding him through instruction, not an attempt to determine victory or defeat.

It's clear he wasn't using his full strength.
