Unwilling to give up, Gu Qingfeng took out another pill and swallowed it. After a while, the vitality in his body began to replenish.

Then he poured all his vital energy into his five internal organs once again.

No response!

Still no response!

"Fuck, this is unscientific. Others use so much energy to refine their five internal organs, and they can stimulate some life essence. Why is it that when it comes to me, even after two peak Qi gathering Qis have been put in, there is no reaction at all? Moreover, my Qi has undergone the transformation of the Black Dragon Immortal Body, and its quality far exceeds that of ordinary Qi gathering..."

At this point, Gu Qingfeng suddenly reacted.

The black dragon is immortal!

He instantly understood why he couldn't refine his five internal organs even with so much energy. It was because the Black Dragon's Immortal Body was too strong!

The combat capability of the Black Dragon's Immortal Body at an advanced level alone is enough to rival that of a sixth-level Dragon Transformation.

Please note that it is the physical strength that is comparable to the sixth level of Dragon Transformation, and the strength of the sixth level of Dragon Transformation is mainly composed of two parts: true essence and physical body.

This means that in terms of single-round physical strength, Gu Qingfeng's body is much stronger than that of the sixth level of Dragon Transformation, and even the body of a peak Dragon Transformation cannot compare to his.

It is conceivable what level the strength of Gu Qingfeng's five internal organs will reach.

When others cultivate the Inner Qi realm, they all refine the five internal organs at the peak of Qi Gathering, but Gu Qingfeng refines the five internal organs beyond the peak of Dragon Transformation.

The difference between the two is like the contrast between a stream and the sea.

Therefore, this is why Gu Qingfeng consumed a lot of his energy but was unable to refine his five internal organs in the slightest.

Just because the body is too strong, the five internal organs are also too strong.

Gu Qingfeng, who had figured everything out, suddenly exploded.

"Is this God's will? God is jealous of talented people, and doesn't want me to break through to the Inner Energy Realm, and doesn't want the system to give me cheats?"

But Gu Qingfeng thought about it again. This might not be a bad thing. It might even be a great thing. Although it was difficult to achieve the inner energy realm and required a huge amount of energy, once it was achieved, how terrifying would the inner energy be?

To what extent would the internal energy refined from the five internal organs that surpassed the peak of dragon transformation be strong?

Will it be directly comparable to the true essence of the Dragon Transformation Realm?

The future is promising!

Gu Qingfeng's heart was burning with excitement, and he started to take drugs like crazy. He kept taking drugs to restore the vitality in his body, and then infused it all into his five internal organs and began to practice.

Although his five internal organs had not responded at all, he was not discouraged. Instead, he became more excited the harder it became.

Because the more difficult it is to refine, the stronger the internal energy will be after success!

By then, I'm afraid that without relying on the physical body, the cultivation of the inner energy realm alone will be able to defeat the grandmaster, right?

......

Time flies, and three days are gone in a flash.

This is the longest retreat Gu Qingfeng has ever had!

It was also the time with the greatest gain!

Because he finally reached the inner energy realm!

After eating most of the pills, he was able to refine a trace of life essence.

Just this trace of life essence, combined with a vast amount of vital energy, finally condensed into a strand of internal energy as thick as a hair.

This strand of internal energy is as black as hair, and really looks like a strand of hair.

But anyone who sees it will be shocked by its thickness. Although it is only the size of a hair, it gives people the illusion that it can crush mountains.

Of course, it's just an illusion, and there's still a little gap between it and reality.

This is the internal energy condensed from the life essence that surpasses the physical body at the peak of dragon transformation, combined with the vital energy contained in the elixir worth tens of thousands of taels of gold.

Gu Qingfeng had fought against both Grandmaster and Dragon Transformation Realm masters, so he naturally understood their levels of power.

So he roughly sensed the quality of this trace of internal energy, and it was actually comparable to the master's innate internal energy.

(The power of the Qi Gathering Realm is Yuan Qi, the power of the Nei Qi Realm is Nei Qi, the power of the Zhen Qi Realm is Zhen Qi, the power of the Gang Qi Realm is Gang Qi, the master's Xiantian Gang Qi, and the Dragon Transformation True Yuan.)

You have to know that this is only the Inner Qi Realm! The Inner Qi Realm is comparable to a Grandmaster.

When one reaches the realm of true Qi, the internal Qi in the body will be transformed into its true form and undergo a qualitative change, with the quality being raised to another level. By then, it will probably be comparable to the true Qi of a dragon.

What about the Gangqi Realm? What about the Grandmaster Realm?

Once you reach the above level, how strong will the power in your body be?

Gu Qingfeng couldn't even imagine it anymore. This was like a little cow taking a plane...

Of course, the above refers to the quality of internal energy, not the quantity. Although the quality has reached the level of a grandmaster, in terms of quantity, it is far behind the grandmaster.

However, the increase in quality also means an increase in the difficulty of cultivation. Just in order to cultivate this trace of internal energy, Gu Qingfeng almost exhausted his medicine reserves, and almost forced him to eat the rare treasures he just took from the national treasury.

If I continue to practice this in the future, I don’t know how much resources will be needed.

Fortunately, demons can help with cultivation, otherwise even if Gu Qingfeng is rich, he would still feel the pain.

Suddenly, Gu Qingfeng stood up with a look of joy on his face, stretched his muscles which had not been moved for three days, and felt indescribably refreshed.

"Swallow a wisp of internal energy into the stomach! My life is in my own hands! Hahaha..." Gu Qingfeng laughed loudly.

Suddenly, Gu Qingfeng's expression changed and he stopped smiling.

Because he sensed that the formation seal of the Yangxin Palace had just fluctuated, and it was obvious that someone had come in.

Sure enough, a moment later, Situ Kong appeared in front of him.

"Has the elixir of immortality been refined?" There was a rare hint of urgency in Situ Kong's tone.

Gu Qingfeng didn't waste any time and directly threw a small jade bottle into Situ Kong's hand.

"Isn't it just a matter of having hands for this thing?"

Situ Kong didn't pay attention to Gu Qingfeng's arrogant words, but his expression was obviously relaxed, and then he asked: "How much life can this immortality pill increase?"

"One year."

"One year!?" Situ Kong was surprised. "The immortality elixir that Qiu Yulong refined back then could extend the life by at least ten years! Why is yours only one year?"

"Qiu Yulong was already a master of alchemy when he created the Divine Refining Method, and I am just a novice who has just started to learn the Divine Refining Method. Shouldn't you be surprised that I made the elixir of immortality on my first try? Rather than being surprised that the effect of the medicine only lasts for one year!"

Situ Kong frowned and didn't say anything more. He turned around and left, obviously not daring to delay for even a second.

"Hey! The elixir of immortality has been made. When will you let me out?"

"Wait a little longer." Situ Kong said without replying.

Gu Qingfeng looked at Situ Kong's hurried back and smiled silently.

It's you who don't let me go out, so don't beg me to go out when the time comes.

"Okay, the mission is accomplished, and I have made significant progress in my cultivation. It's time to relax." Gu Qingfeng muttered.

Then he shouted outside: "Come quickly, the king wants to eat."

"Yes, Your Highness." The palace maid outside the door hurriedly said yes, and then went to prepare the meal.

Gu Qingfeng had no idea how many pills he had taken in the past three days. Now his mouth was full of the taste of medicine. He really wanted to eat some delicacies to suppress the stench.

After finishing eating, take a bath to get rid of the smell, and do a massage to relax your muscles. It feels really good.
