bedrooms, in the midst of accelerated space.

Lin Meng sat cross-legged, his eyes slightly closed, the Refining Gang Secret Book was divided into four layers, and the cultivation methods of each layer were different.

The first layer is mainly to absorb the aura in the space, which is involved in the abdomen, constantly refined, tempered and polished, and created Gang Qi.

The moment the first wisp of Gang Qi was generated, the first layer of the Tiangang Secret Archive was considered an entry.

However, Lin Meng didn't need that, he had spiritual energy beads in his body, so he didn't need to spend a lot of time swallowing spiritual energy.

Sitting cross-legged on the ground, concentrating, sensing the aura bead suspended in the lower abdomen, Lin Meng followed the method of refining and polishing the Gang Qi in accordance with the Gang Secret Classic, prompting the aura bead to vibrate at a special frequency.

The inner force has a spirit and will respond to the master's thoughts.

In his mind, he imagined the refining method of refining the Gang Secret Codex, and the aura beads obeyed Lin Meng's thoughts, and they kept vibrating again and again.

The tinkling sound reverberates crisply, like a blacksmith in a blacksmith refining pig iron.

Made of ferrotechnic steel!

The process was not long, and the aura beads were vibrating again and again, shrinking in size, and the density of the internal force wrapped around the surface of the aura beads was constantly increasing, and the power was becoming more and more powerful.

The sound of concussions continued again and again, about half an hour later.

There was a slight shock in the lower abdomen, and there was a wisp of darker white mist on top of the spiritual energy bead.

Far deeper and more powerful than the internal force!

The first wisp of gas is formed!

The powerful power of the thick white patch, even if Lin Meng can't look inside, he can feel the power of a wisp of qi inside, far above the internal force.

And this is just the beginning, the birth of the first wisp of Gang Qi represents the introduction of the Gang Refining Secret Codex, but if you want to step into the second layer of the Gang Refining Secret Codex, you need a hundred wisps of Gang Qi.

This is a long cultivation time, but Lin Meng has a foundation!

The acceleration space time is constantly passing, and the sound of tinkling and tempering in the spiritual energy beads is continuous.

With the help of the first wisp of Gang Qi, Lin Meng tempered Gang Qi faster and faster.

Ten minutes later, the spiritual qi beads in the lower abdomen shook, and the second wisp of Gang Qi formed.

....

Twenty minutes later, the third and fourth wisps of Gang Qi formed.

....

An hour later, the tenth wisp of Gang Qi...

....

Two hours later, the thirtieth wisp of Gang Qi...

....

...

..

Four hours later, when the last wisp of internal force of the spiritual qi bead suspended in the lower abdomen shook violently and transformed into gangqi, at that moment, Lin Meng's body was filled with a strong momentum, like a diamond, indestructible and thick, lasting for a few seconds and then gradually disappearing.

Lin Meng, who had been concentrating, breathed a sigh of relief slightly,

"The Gang Qi Bead is done."

Through the continuous polishing of the blacksmith's tempering method, the aura beads suspended in the lower abdomen completely disappeared, and the slowly internal force all turned into gang qi beads!

The energy stored by the Gang Qi Bead is more than twice as much as that of the Spiritual Qi Bead, but the strength is also much stronger!

"Overall, my strength should have increased, but it didn't last as long as it used to be."

Lin Meng, who was sitting cross-legged on the ground, clenched his palms into fists, feeling the fierce power contained between the fists, as well as the total amount of gangqi, and slowly made an evaluation.

I'm afraid that if I burst out with all my strength, my strength will be exhausted in ten minutes.

Next, he had to fight Wu Long, a first-class martial artist, and the duration of ten minutes of Gang Qi was not safe.

Need more gang!

Lin Meng closed his eyes and felt the Gang Qi beads in his body, and the total amount of Gang Qi was currently seventy-three wisps.

There are still twenty-seven wisps of Gang Qi left to be able to save up to one hundred wisps and break through to the second layer.

At that point, a person without any martial arts skills is enough to fight with a first-class martial artist for a long time, and a person like Lin Meng, who has a lot of actual combat experience, is not afraid of being a first-class martial artist!

The hour hand of the gold pocket watch keeps turning, and the time acceleration continues.

Without any stops, Lin Meng started a new cultivation!

The internal force in the aura bead has all been converted, and if you want to get a new Gang qi, you can only extract the aura from the air for conversion, which will take a long time, but it doesn't matter, Lin Meng has room to accelerate!

Breathe, breathe, breathe, breathe...

And so on and so forth.

The aura contained in the air in the city is too thin, Lin Meng is practicing the top exercises here, and he always feels like he has half the effort, but there is no way, he has no better place, so he can only insist.

Tempering, consolation, and so on,

After about six hours, the seventy-fourth ray of Gang Qi merged into the Gang Qi Bead.

.....

After about twelve hours, the seventy-fifth wisps of Gang Qi took shape....

....

After about thirty hours, the seventy-eighth wisp of Gang Qi was formed....

....

Fifty hours later...

....

Sixty hours later....

....

Eighty hours later....

....

The acceleration space was quiet, the hour hand of the golden pocket watch kept rotating, Lin Meng repeated the breathing and exhalation concussive action, and the qi between the chest cavity accumulated strongly, and it lasted for hundreds of hours, and his body was faintly swollen.

This is the discomfort caused by the body's ability to increase too much power in an instant, and the physical body cannot keep up.

But in the same way, the ninety-ninth wisp of Gang Qi has been integrated into the Gang Qi Bead!

"It's just the last wisp left."

Lin Meng whispered in his heart, only the last wisp was missing, and he could step into the second layer of the Gangqi Secret Classic, and from then on he would be among the first-class!

But in the same way, Lin Meng knew very well in his heart that the formation of the last wisp of Gang Qi was more difficult than the previous ninety-nine wisps.

Breaking through the realm and breaking the bottleneck is never an easy thing.

But...!

The palm of his hand pressed against his chest, and the corners of Lin Meng's mouth opened a little, he deliberately stored the blood sacrifice energy until now, just for this time!

In an instant, the cold energy hovering in the chest, under Lin Meng's will, quickly rolled into it and merged into the lower abdomen qi beads.

The majestic blood sacrifice energy was injected into the Gang Qi, constantly transforming and fused, turning into a part of the Gang Qi Bead, and the total amount of Gang Qi contained in Lin Meng's body soared rapidly, and at the same time, the Gang Qi Bead, which had been stuck in the ninety-nine wisps, easily broke through to the hundredth wisp.

A hundred wisps of Gang Qi are formed in an instant!

In that moment....

Rumble!!!

There seemed to be a thunderous explosion in his ears, and faintly, the young man's body seemed to be surrounded by cotton white wadding.

The real world.

Lin Meng, who was leaning on the chair, suddenly opened his eyes, and when he fell into his eyes, it was a flickering table lamp, which seemed to be about to break.

But Lin Meng paid attention to those in every mood, and at this moment he clearly felt that there was a strong force in his body, like a volcanic eruption, powerful and boundless, making it difficult for him to adapt!

Lin Meng, who had several experiences, knew that this was the embodiment of a large increase in strength in an instant.

"At least up 30 percent, no! Maybe even more..."

Lin Meng whispered, estimating that his strength had increased, and this was only an increase in physical strength, and the increase in Gang Qi was even more difficult to calculate.

And, most importantly...

The Gang Qi Bead is split!

The surging power was suspended in the lower abdomen, and Lin Meng could clearly feel that there were two Gang Qi beads there.

This represents greater power, longer combat time.

"It seems that there are new abilities."

Lin Meng stretched out his palm, and with a movement of his mind, the majestic Gang Qi surged out, turning into a thin film attached to his arm, compared to the thin film formed by the spiritual energy beads, the Gang Qi film at this moment was simply like a diamond, calm and unshakable!

Sitting on the chair, Lin Meng felt the explosive power in his body, and he could clearly see that his strength had completed a qualitative leap this time.

That's a good thing!

But...

opened the drawer, took out the mirror in the drawer, and put it in front of him, reflecting Lin Meng's appearance.

In the mirror, the black-haired young man, with black eyes and white eyes, I don't know when, wisps of bright red loomed.

The side effects of the Blood Sacrifice Energy are here again!
