Ignoring the pungent and spicy taste, Jiao Yi picked up a heart cultivation elixir and put it into his mouth.

The medicinal power quickly dissipated, and there was a pinprick pain in the heart, but compared to the pain when taking the Huayang Pill, it was nothing.

When the stinging sensation was about to disappear, Jiao Yi immediately sent in another Heart Cultivation Elixir to open the central channel, and a total of eight Heart Cultivation Pills were needed.

After taking all the eight heart cultivation elixirs, Jiao Yi could clearly feel that there were more than ten meridians around his heart, each of which was connected to the eight Ming veins, and a single meridian was not too long, but it was better than the number.

Jiao Yi was ecstatic, he knew that his central channel was opened!

When the central channel was opened, Jiao Yi naturally wanted to improve his strength first, firstly, he also wanted to verify how powerful the fourth hidden vein was, and secondly, only by improving his strength could the parasitic soul remember the Danfang of the Heavenly Fury Pill, and the old guy's memory was gradually restored with the improvement of Jiao Yi's strength.

In addition, the parasitic soul also said that Jiao Yi's current primary immortal qi is not stable enough, and only when the middle channel is opened can the primary immortal qi be truly cultivated, and it is possible to cultivate the intermediate immortal qi.

Putting away the rest of the Heart Cultivation Pill, Jiao Yi took out ten Qi Gathering Pills in one fell swoop.

One by one, the Qi Gathering Pill entered Jiao Yi's abdomen, and a large amount of dense heaven and earth aura spread out in Jiao Yi's dantian meridians, Jiao Yi ran the internal strength method at full speed, and all the heaven and earth aura was incorporated into the newly opened central channel.

The ninth Qi Gathering Pill went down, and Jiao Yi felt that more than ten central channels connected to the eight Ming Pulses were gradually saturated, and he did not forcibly inject true qi into the central channels.

However, Jiao Yi was already very satisfied, the opened mid-channel was more powerful than the spiritual vein and the suspension vein combined!

Moreover, Jiao Yi could feel the air flow around him, which was thicker and tougher than before, and with the faint light in Shennong's tomb, he could see that it was a pale yellow halo.

Intermediate Immortal Qi!

When the central channel is opened, not only is the primary immortal qi completely stable, but the intermediate immortal qi is also out!

The middle vein is already so powerful, Jiao Yi is even more looking forward to opening the mad vein, according to the parasitic soul, the last four veins and the first four veins of the eight hidden veins are qualitatively different, starting from the mad vein, the number of open vein pills needed will skyrocket.

Just by opening the mad vein, it will cost eighty-eight sixty-four Heavenly Fury Pills!

In the future, every time you open a pulse, the number of Pulse Opening Pills required will double!

If in the past, every time he refined the Open Pulse Pill, Lao Junding would have to strike for several months, and refining a large number of Open Pulse Pills was indeed not an overnight thing, but now with the Eclipse Sun Burst Yan Ding, the number of pills refined each time is more, not to mention, the Danding does not need to rest, and the opening of the eight hidden veins has become within reach.

There is no shortage of alchemy materials, and Danding also has it, so what are you waiting for!

"Senior, my midrib is open. Jiao Yi immediately communicated with the parasitic spirit.

"According to the method I said, refining the heart cultivation elixir and opening the central channel is a logical thing, what's so strange?" the parasitic soul said angrily.

"Uh, senior, I mean, the midrib is open, and the internal structure of the Eclipse Sun Burst Flame Ding has not been destroyed, and you can start refining the Heavenly Fury Pill. Jiao Yi didn't dare to argue with the parasitic soul.

"Oh, if you want to refine, then refine. "Parasitic souls are understated.

Jiao Yi was stunned for a moment, and then he felt the urge to scold.

Lao Tzu wants to refine the Heavenly Fury Pill immediately, but what spiritual herbs and immortal elixirs do the Heavenly Fury Pill Lao Tzu doesn't know, and there is no Dan prescription, refining your old mother?

It's just that Jiao Yi's dissatisfaction didn't dare to let the parasitic soul know, so he kept silent at the moment, and he didn't believe that the parasitic soul could really calm down.

To Jiao Yi's surprise, for a long time, the parasitic soul did not communicate with Jiao Yi, as if he had fallen asleep, but Jiao Yi knew that the parasitic soul at this time would never have the heart to sleep.

After all, if the parasitic soul wants to connect with Shennong himself, he must guide Jiao Yi to refine the Open Pulse Pill, open the eight hidden veins, and cultivate into a Mahayana True Immortal.

"Senior, what spirit herb immortal elixir do you need to refine the Heavenly Fury Pill?" In the end, Jiao Yi couldn't help it.

"Don't bother me, I have to think carefully about the materials and pills of the Heavenly Fury Pill. "The parasitic soul is still awake.

However, the parasitic soul's words surprised Jiao Yi quite a bit: "Senior, you haven't even remembered the pill recipe of the Heavenly Fury Pill?"

In the past, every time Jiao Yi's strength increased, the parasitic soul would immediately be able to remember something new, but this time the parasitic soul was unable to recall the pill recipe of the Heavenly Fury Pill, which was really unusual.

"Starting from the Heavenly Fury Pill, the Dan recipe and refining method are much more complicated than the previous Open Pulse Pill, and the materials of these high-grade Open Pulse Pills are very precious, and there can be no mistakes. The parasitic soul's tone became serious.

The parasitic soul hadn't yet remembered the Danfang of the Heavenly Fury Pill, no matter how anxious Jiao Yi was, he could only wait, and asked carefully: "Senior, how long will it take for you to recall the Danfang?"

"I can't tell. For the first time, the parasitic soul had no confidence, "Then don't bother me again, I'll let you know when I think clearly." ”

Then, the parasitic soul was silent, and Jiao Yi didn't dare to ask rashly.

Idle, Jiao Yi simply cultivated the "Chao Song Day Method", although cultivating the qi aperture is far less than opening the hidden vein, but opening up all the qi apertures, the strength improvement brought by it is also considerable.

The stronger the strength, the greater the certainty of facing Genno Sato in the future.

In fact, after leaving the high-level ancient martial arts realm, Jiao Yi has been trying to cultivate qi techniques, but the effect has not been very significant.

He had also used the Quenching Tendon Spirit Pill, but it had no effect on his meridians at all, and it was no wonder that his meridians had been quenched in the Blood River Great Array, and the tempering strength was much stronger than the Quenching Tendon Elixir.

But it's not in a hurry to think about it, under normal circumstances, it takes four or five years to cultivate the Qi Aperture, even if you have the Quenching Strength Elixir, you have to cultivate for several months, and Jiao Yi doesn't expect to complete a few months in a few days.

But this time, as soon as Jiao Yi ran "The Secret of the Song of the Sun", he obviously felt the difference.

First of all, there are three bags bulging on the tendons of the Yin Pulse Vein, each of which is the size of a thumb, and then, five bags appear on the tendons of the Yang Pulse Vein!

Next, the Yang Dimension Pulse, the Yin Dimension Pulse, the Chong Pulse, and the Belt Pulse ...... There are a different number of bulges on the tendons of each vein!

Breath of the air!

It's finally time to cultivate the Qi Aperture!

Although each qi point is still very small, as long as the qi point appears and continues to cultivate, it won't be long before you will be able to store true qi!

It's just that Jiao Yi didn't understand for a while, even if he had the best tempering elixir, he had to cultivate for at least three months before his qi trick appeared, and it was less than ten days since he got the "Chao Song Chasing the Sun Technique", how could he cultivate the qi knot?

After thinking about it for a long time, Jiao Yi still didn't dare to be completely sure, it is estimated that in addition to the more clever "Chao Song Chasing the Day", the main reason is that he opened the central channel!
