Returning to Lingyuan Mansion, Tong Yu took out the drop of thunder source liquid sealed in the jade.

Tong Yu's cultivation on weekdays is mainly based on the strong Heaven and Earth Yuan Qi of the Ling Yuan Mansion and the Qi and Blood Yuan Qi in the refining blood marrow.

He cultivated the Five Thunder Fa, and there were very few things in the True Demon Palace that could assist him in his cultivation.

Unlike other True Demon Palace disciples, there are True Demon Pills, as well as demonic qi and so on that can speed up cultivation.

In order to achieve a perfect Dao foundation, he tried not to take pills to improve his cultivation as much as possible, so as to avoid an unstable foundation.

Step by step, the biggest problem is that the cultivation speed is slow.

What's more, he also cultivated the Red Yuan Bronze Body, which was a form refining technique, which even dragged down his progress in qi refining.

Now, among the new disciples, except for him, almost all of them have broken through to the Refining Yuan Realm.

"Although I want to achieve the Infinite Dao Foundation, I can't be too slow than others in terms of cultivation speed, otherwise I still won't be able to achieve it after the prime of life, and my body's qi and blood will start to decline, and it will be even more hopeless. ”

Tong Yu took the jade that sealed the Thunder Source Liquid with a serious expression, and with the special technique taught by Elder Nie, he began to open the ban with the vitality in his body.

When the breath of Lei Yuanye leaked out, the thunder spirit in his dantian suddenly became excited, and Tong Yu could clearly feel the joy and beating of the thunder spirit.

When a trace of thunder source liquid was introduced into Tong Yu's body, it suddenly turned into a rolling heavenly thunder essence, filling his meridians.

These Heavenly Thunder Essence Qi is not violent, on the contrary, it is relatively docile, because the Thunder Source Liquid is condensed after the Heavenly Thunder Essence Qi is refined.

Of course, there are also natural thunder source liquids, but this drop is obviously not.

Tong Yu guided the Heavenly Thunder Essence Qi that entered the body to operate in the body according to the Five Thunder Righteous Method, while the Thunder Spirit in the dantian greedily absorbed these pure thunder and lightning essences.

Unconsciously, Tong Yu fell into a deep level of cultivation.

The huge Heavenly Thunder Essence Qi provided by the Thunder Source Liquid became the unique Five Thunder Essence Qi in his body after refining it over and over again.

And the thunder spirit plays an extremely crucial role in it, after these thunder essence qi is absorbed by the thunder spirit, it will be more smoothly transformed into the vitality in Tong Yu's body.

I don't know how long it took, Tong Yu's meridians were completely filled with a huge amount of five thunder vitality.

He could no longer absorb even a little bit of Thunder Source Liquid, or Heavenly Thunder Essence, this was his limit.

Not only the meridians, but even the whole person had a feeling of swelling.

When Tong Yu opened his eyes, he found that he had absorbed less than one-fifth of the Thunder Source Liquid, and there was still most of the Thunder Source Liquid, which had been re-sealed in the jade by him.

"Is it possible to break through the fetal yuan aperture in one fell swoop and step into the realm of refining yuan, it is here. ”

Tong Yu took a deep breath and slowly closed his eyes.

Opening the Fetal Yuan Aperture and stepping into the Refining Yuan Realm is the first level on the path of every monk's cultivation.

When the vitality is full enough, the monk will try to impact the fetal yuan and step into the realm of refining yuan.

It's just that not many people can be as extravagant as Tong Yu, relying on Lei Yuan Liquid to let the vitality in their bodies reach the limit and fill to the extreme.

With the strange cold power of the black mist, he made his soul clear, and operated the vitality in his body over and over again, and when his state reached its peak, Tong Yu began.

The huge vitality in his body was guided by his mind, and he rushed towards an unfamiliar meridian acupoint.

This is exactly the fetal element that gradually closes after being born from innate breathing to acquired breathing.

No matter how docile the thunderbolt attribute energy is, it is more violent than other vitality.

When Tong Yu had the heart to guide the impact fetal element, the vitality in his body immediately rushed away like a torrent, and the rolling torrent rushed away, unstoppable all the way.

"Boom!"

Tong Yu only felt a shock all over his body, as if the torrent had encountered an iron dam, the fetal yuan was also shaking, but it was not opened once.

However, as soon as the head of this wave went down, a steady stream of flood peaks followed.

A ** thunderbolt energy continued to impact, and in the end, Tong Yu only heard a silent explosion.

The fetal element aperture was opened, like opening the floodgate, and the vitality in his body suddenly poured into the fetal aperture.

At the same time, some strange vitality also overflowed from the fetal elemental aperture, which gradually merged with the thunder and lightning vitality in his body.

This is the innate vitality, after he was born, the innate vitality escapes, and these are the innate vitality that has not yet dissipated.

The innate vitality is extremely wonderful, although the amount is very small, but after fusing with those thunder and lightning vitality in Tong Yu's body, it is dominated by innate vitality.

And the vitality that was originally filled to the extreme in Tong Yu's body gradually began to condense and began to decrease, as if it had shrunk.

He stepped into the Refining Yuan Realm!

Refining the Yuan Realm, as the name suggests, is to condense the Yuan Qi.

Although the vitality in the body is full, these vitality is scattered, scattered but not condensed, and cannot penetrate the body.

Refining the Yuan Realm is to remove the scattered vitality and condense it into one, so as to achieve condensation but not dispersion.

Therefore, the vitality in the body of a cultivator in the Yuan Realm is far from being comparable to that of the Yuan Cultivation Realm, and it is much more condensed, which is the gap in essence.

After the breakthrough, although the vitality in Tong Yu's body shrank, the quality was much higher than before.

"The Yuan Refining Realm has something in common with the Blood Refining Secret Technique. ”

After Tong Yu opened his eyes, he said thoughtfully: "The secret technique of blood refining is to condense qi and blood, let one's own qi and blood condense, and initially achieve the initial level of dripping into the water without dissipation, but this is more difficult than refining qi." ”

Tong Yu couldn't help but sigh, he could be said to have cultivated for the longest time in the blood refining secret technique, and the cultivation conditions were the best.

There is no better condition than the drop of blood marrow provided by the blood man, the qi and blood are endless, and it does not consume itself.

But even so, he still hadn't yet preliminarily practiced the secret technique of blood refining, and he hadn't been able to make a drop of blood drop into the water and not disperse.

"Refining the Secret Technique is much more difficult than refining Qi. ”

Tong Yu shook his head, not only the secret technique of blood refining, but also the cultivation of the Chiyuan Bronze Body was also very difficult.

Except for when he first got the Blood Crystal Copper Heart, the progress was extremely rapid, and he became a small success in a short period of time, but then his cultivation speed slowed down.

Although it is said that the skin of his whole body is already brass-colored when he operates, it has not yet reached pure brass, and it is not yet a complete achievement.

"Let's try to see what the difference is in the Refining Yuan Realm first. ”

Tong Yu ran the thunder and lightning vitality that fused the innate vitality in his body, and then used the method of five thunder palms to make a palm.

"Zz!"

Seeing this palm hit, his palm was no longer the previous thunderbolt, but a beating arc.

Although it was the void that slapped its palm, the air made a zizzle sound when it touched the thunder arc.

Although he had just entered the Refining Yuan Realm, Tong Yu had not yet been able to injure the enemy through the air, but the power of the Five Thunder Palms was much greater than before.

"It's much stronger than I expected, and this is just stepping into the Refining Yuan Realm. ”

Tong Yu was pleasantly surprised, and tried the Five Thunder Seals again, and found that the Five Thunder Seals were also very powerful.

And when it came to the realm of refining yuan, the five thunder seals also had some more complex changes.

"The Five Thunder Fa is worthy of being one of the top foundation laying exercises, although the old fox of the Dharma Transmission Hall Master is cunning, but the Five Thunder Fa has not deceived me. ”

Tong Yu had a bright smile on his face, although he also knew that the reason why the Five Thunder Righteous Method he cultivated had such great power had a lot to do with Lei Luo and Lei Yuanye, but the power was real.

In addition to the changes in the Five Thunder Palms and the Five Thunder Seals, when you reach the Refining Yuan Realm, you can also use several other methods recorded in the Five Thunder Rectification Method.

For example, the Thunder Finger, after the condensation of the Yuan Qi in the body of the Refining Yuan Realm, as soon as it is pointed out, it can pierce the golden cracked stone in the air, which is extremely powerful.

There is also a thunder knife, which binds qi as a knife, and condenses a thunder knife with thunder and lightning vitality, not only the ferocity of the knife, but also the fury of thunder and lightning, which is extremely difficult to resist.

Tong Yu found that most of the methods recorded in the Five Thunder Rectification Methods were powerful, giving full play to the characteristics of thunder and lightning, and far surpassing the ordinary foundation building techniques in terms of attack power.

After breaking through the Refining Yuan Realm, Tong Yu quietly cultivated in the Lingyuan Mansion to consolidate his cultivation.

On this day, when he was cultivating, a demon butterfly passed through the prohibition of Lingyuan Mansion and arrived in front of him.

"Demon Butterfly?"

Tong Yu's eyes suddenly tightened, staring at the demon butterfly dancing around him.

The last time because of the Demon Butterfly's arraignment, he was late and was sent to the blood prison, and I still remember it vividly.

This was the second time he had seen the Demon Butterfly, and his heart couldn't help but rise.

After a little groaning, Tong Yu stretched out his hand, and the demon butterfly stopped in his palm.

"Three months of entry, the first trial?"

Tong Yu muttered.

The news brought by the Demon Butterfly was very simple, these new disciples had been initiating for three months and were about to start their first trial.

At the mention of the trial, Tong Yu's heart couldn't help but beat.

Not for anything else, it's just that the trials in the True Demon Palace are very cruel, and there may be deaths and injuries for disciples in every trial.

The identity of Tong Yu's true disciple is not very useful in the trial, and it is even a burden, he, a true disciple, still has to work hard in the trial, and he may also die.

True disciples have received so many benefits, so naturally they have to prove their worth.

On weekdays, Tong Yu cultivates in the True Demon Palace, and the Gongfa Cave Mansion is the best, but he also thinks that the True Demon Palace is very good.

But when encountering trials and tasks, the True Demon Palace, as a major faction of the Demon Dao, suddenly manifested the ferocity of the Demon Dao.

The next day, Tong Yu arrived at the Heart Washing Hall early, he didn't want to be framed twice in the same way.

When he arrived, there were already a few disciples in the Heart Washing Hall who had arrived first.

They were discussing this trial with excitement or worry, and when they saw Tong Yu coming, a disciple named Yan Feng asked, "Senior Brother Tong, do you know the details of this trial?"

Tong Yu shook his head and said, "I also got the news yesterday, and the situation of each trial is different, who knows how it will be arranged this time." ”

Several people were a little disappointed when they heard this, but Yan Feng still said: "I heard that the first trial of a new beginner disciple is the easiest to complete somewhere in the sect, and there are the fewest casualties. ”

"The most unlucky thing is to go down the mountain, and fight with the disciples of other sects who are enemies of my True Demon Palace, in case of some accidents, we may even suffer heavy casualties, I hope we will not be so unlucky. ”

When Tong Yu heard what he said, his heart couldn't help but feel a little heavier.
