"Iron Bull Gong" is a book of internal strength, which looks a bit like "Supreme Breath Internal Strength Method", but the two not only have different emphasis, but also have completely different essences.

The latter is mainly to strengthen the internal organs, strengthen the qi and blood by the way, and develop it in the direction of inhuman, but in terms of classification, it is actually more inclined to be a health preservation kung fu similar to primary martial arts, but the effect of this health martial arts is too powerful.

On the other hand, "Iron Bull Gong" is clearly written on the title page, and it is an extremely masculine hard skill, the kind of hard skill that has the ability to resist the enemy, but has no magic in controlling the enemy!

If it is said that the "Supreme Dragon's Breath Internal Strength Method" is to strengthen the five internal organs, then the "Iron Bull Gong" is to put another layer of armor on them, and even connect them into a whole, including all the organs, and even the entire chest cavity, and jointly build a steel and iron castle, so that there is no longer any danger of damage from some ruthless and tricky penetrating strength.

Li Yun even suspected that once he practiced the "Iron Bull Gong", coupled with Dacheng's "Supreme Dragon's Breath Internal Strength Method", not to mention the strength, he might even be able to resist the true qi of a martial artist in the Qi Condensation Period.

However, this skill is powerful, and it can be regarded as making up for one of his shortcomings, but it can make up for his physical strength-

"Obviously they are all ordinary, and the practice method is also clearly written, but once they are all practiced, they will suddenly turn into wonderful superb martial arts, giving birth to unbelievable characteristics. ”

Li Yun put down the cheats and couldn't help but sigh in his heart.

Although he was still puzzled, in view of his martial arts knowledge at the level of a middle school student, he could only choose to temporarily believe in the power of the "Dragon Roaring Tiger Roaring Internal Hard Body Protection Skill".

And now—

He looked at the spirit core on the table, his eyes showing exploration and expectation, and reached out and twisted one.

This is a second-order spirit core, which looks crystal clear, round and full.

And unsurprisingly, the prompt sound of morning light instantly sounded in Li Yun's ears.

[Ding, an unknown energy reaction has been detected, can it be absorbed, can it be absorbed?]

"Absorption. ”

Li Yun replied in his heart.

As soon as the thought fell, the palm of the hand immediately cooled, like a trickle of spring flowing through it, and then disappeared in the arm.

After three breaths, Li Yun's fingertips loosened, and the spirit core turned into flying ashes.

And throughout the process, his eyes were always firmly fixed on the small frame of the morning light, looking at the energy bar below it.

After absorbing the spirit core, there were naturally changes, but this change did not exceed Li Yun's expectations, but it was far lower than his expectations.

"Ten more energy. ”

Disappointment inevitably flashed in his eyes, Li Yun retracted his gaze and couldn't help muttering, "Could it be that there is only a gap in energy level between high-level spirit cores and low-level spirit cores?"

The first-order spirit cores are all a little bit of energy each, and the second-order has directly increased tenfold, which seems to have improved a lot, but the essence has not changed.

You must know that although Li Yun spent a lot of energy in the crazy accumulation of primary martial arts, there were still hundreds of thousands of gold coins and golden tickets collected by Zhang Li, because of the huge amount, all of them were sent by first-order spirit cores a few days ago, so the last thing he lacked at this time was energy.

"Could it be that I am insatiable and think too much?"

"Or is that the function of the morning light is only that, and it has nothing to do with what level of spirit core it absorbs?"

Or ...... The second-order spirit core is still too low, and there is no essential difference with the first-order spirit core?"

Thinking of this, he immediately looked at the only third-order spirit core on the table, and without any further hesitation, he directly grabbed it and began to absorb it.

Suddenly, a clearer and cooler energy poured in from the palm of his hand, like a turbulent mountain stream and a small river, quickly spreading from his right hand to the entire upper body, although it was also disappearing rapidly, but in such a short period of time, it also made Li Yun feel a few points cold on his body, and his pores subconsciously closed.

And the original unchanged morning light small frame, at this time finally there is a significant change!

"It's—"

Li Yun's eyes widened.

I saw that under the morning light, on the right side of the energy bar, a light blue number bar appeared again, showing 10 inside, because of the background, as if the number was frozen in the ice, looking quite dreamy.

The original energy bar also changed, but the energy increased by ninety points again, and the total number of numbers on both sides was exactly one hundred, which immediately made Li Yun perceive the connection.

"The increased energy is a total of one hundred points, this is the energy transformed by the third-order spirit core! After the morning light absorbs it, it decomposes a part of the new energy! These ten points of energy should be the difference between the second-order and the third-order cultivation in essence!"

Li Yun immediately determined the origin of the new number column, but while he was excited, he also wondered, "What does it do?"

Since the new energy is displayed separately from the original energy, it naturally has different effects, and the old energy is used to improve the skill level, but what about the new energy?

Li Yun thought excitedly, and at the same time, his gaze kept sweeping on the skill bar.

You must know that in the previous life, Chenguang's only role was to modify skills, and now, he doesn't think that the role of new energy will have nothing to do with skills.

In the end, his gaze paused, and stopped at a primary martial art that was already at the full level, which was the first martial art he had learned in this body, "One Qi Green Pine Immovable Pile", and he tentatively said in his heart: "Raise one level of One Qi Green Pine Immovable Pile?"

When the words fell, Li Yun couldn't help but hold his breath, but after two or three breaths, the morning light did not change in the slightest.

"Raise the Bull Fist by one level?"

He didn't give up immediately, but said again.

But the morning light remained the same.

"Isn't it breaking the level cap? ”

The brilliance in his eyes faded, and Li Yun muttered.

He wasn't much disappointed, but thought about it again, and when his eyes scanned, the dense skill bar continued to move up and down with his thoughts, showing more than a hundred martial arts skills inside.

Among them, almost all martial arts are already gray icons, which means that they have reached the full level, and the only one that does not have a full level of the "Supreme Dragon's Breath Internal Strength Method", the words "Level 3" displayed on it are also blurred, after all, it has just been upgraded, and there are still many days before the cooldown ends.

Li Yun had already discovered that like this kind of hard skill or internal strengthening method, the cooldown time of each upgrade increases with the level, while the ordinary yellow-level body refining martial arts will not be like this, whether it is the Brute Bull Fist or the Sweeping Leaf Leg Method, the cooldown of the upgrade is very fast, basically not more than three days.

This may be related to the fact that the body refining martial arts can directly pry the cultivation and carry out linkage promotion, as long as the skyrocketing cultivation can be consolidated, the cooldown can be restored immediately.

Hard skills and the like focus on strengthening, and each upgrade cannot strengthen the body in place at one time, and it will take a while to transition.

The situation on the skill bar made the "Supreme Breath Internal Strength Method" like a little green among thousands of flowers, and it immediately fell into Li Yun's eyes, which also made his mind turn sharply.

At this time, there are two types of martial arts on Chenguang, even if you use the elimination method to speculate, that's-

"Is this really the case?"

Li Yun suddenly thought of some possibilities, hesitated slightly in his heart, and still said silently: "Ascension-Supreme Breath Internal Strength Law Level 1?"

And the next moment.

I saw that on the right side of the Supreme Dragon's Breath Internal Strength Method, the originally vague words "Level 3" had really changed......
