This kind of wholehearted devotion can be said to be extremely hard, even the Yun family was frightened by Yun An, but in fact, Yun An really did it.

Tonight is the moment when he is going to break through the foundation building period and enter the Jindan period, the Yun family hopes that Yun'an can succeed, and he is looking forward to it.

But now everything is ready, and even the most difficult purple silver pill Yun'an has been successfully refined.

In the middle of the night, feeling the silence outside, Yun'an began a breakthrough in the Jindan period.

After three years of hard cultivation, he was finally about to break through a big realm, and Yun An was naturally very excited.

He took out the purple silver pill that had been refined and swallowed it directly, and the air flow in his body came out of the dantian again, flowing along the meridians.

Yun An felt that the air flow in his body had completely changed, becoming more active and more abundant than before, and two small True Qi rivers had formed in the dantian, and these two True Qi rivers formed two whirlpools under Yun An's control.

Yun An controlled these two whirlpools, rotating slowly, as the whirlpools rotated, the air flow in the dantian continued to inject into these two whirlpools, and Yun An's true qi became stronger and stronger.

Gradually, the dantian in the body seems to gradually become a solidified state, and the solidified state is getting more and more rounded, looking like a golden pill.

"Jindan period, isn't this Jindan?" Yun An's heart was ecstatic, because as this air flow continued to converge, he could feel that the golden pill formed by this was originally the kind of illusory golden pill similar to liquid, but now it was forming a hard golden pill that was becoming stronger and stronger.

"Jin Dan Cheng, that is the Jin Dan stage, and if you want to cultivate into the Jin Dan stage, that is, you must let the Jin Dan be completely solidified." The Yun family reminded directly on the side.

Yun An also understood that he was almost at a critical period of cultivation now, and if he wanted to make the Jin Dan completely solidify again, the energy needed was indispensable.

It is far from being able to absorb the surrounding energy alone, even if the meridians of Yun An's body have all been opened, it is still not enough to absorb the energy to the maximum, and at this time, the role of the purple silver pill is extremely important.

With Yun'an's cultivation, the purple silver pill in the body also released powerful energy, and along Yun'an's meridians, it quickly gathered in Yun'an's dantian like a torrent, and the reinforcement condensed layer by layer in the dantian position.

Soon, Yun'an's dantian position was gradually full, and Yun'an continued to exert his internal strength and mental method to continuously compress the illusory golden pill formed.

Jin Dan solidified a little bit every time he pressed a layer, and it was constantly pressed and solidified repeatedly.

Finally, after compressing continuously for a full hour, Yun An stopped the compression action just now.

Because it was really irrepressible, what he had to do now was to transport the energy released by this purple silver pill to various parts of the acupuncture points in his body and store it.

Then make a final breakthrough, everything was ready, and Yun An's whole body was like an inflated balloon inflating wildly.

"It's time for a breakthrough." "Bang!" The power in Yun An's body erupted vigorously, spurting out in all directions.

The internal force is overflowing, which has reached an extremely high level.

With the dispersion of the internal force, the golden pill in the Yun'an Dantian was also peeled off layer by layer, and the golden pill body inside released an incomparably bright brightness.

Yun An suddenly opened his eyes, and then looked around, only to see that his gaze seemed to be farther away than what he could see before.

The whole body is in an extremely comfortable state, and the control of the surrounding energy seems to have reached a higher level.

"This is the Jindan period, it is really full of internal strength, and it is extremely refreshing." Yun An and the Yun family said directly.

"Haha, you really didn't disappoint me, now that Jin Dancheng is complete, you can continue to cultivate more high-level exercises, so that your strength will be stronger, and cross-level combat is a certainty." The Yun family said with great joy.

"Then according to what you said, how many levels of masters can I fight against now?" Yun An asked directly.

"You are now at the first layer, and there is no problem in fighting against the fifth layer of the Jindan period, of course, if you cultivate a higher-level exercise, then there is no problem in fighting against the seventh layer." The Yun family said immediately.

Hearing him say this, Yun An knew that he was one step closer to his goal of becoming a powerhouse.

Then, before he could say anything, a book appeared in his mind.

When I opened it, it was "One Hundred and Eight Swords for Demon Slaying".

This set of sword techniques is an enhanced version of the previous sword techniques, and at this time, countless sword qi is constantly surrounding Yun An's mind.

Just looking at this flying sword qi, Yun An knew that the exercises he was cultivating now were several times stronger than before.

It is worthy of the swordsmanship given by the Yun family, and this swordsmanship has reached a more advanced level.

"Tell you that the swordsmanship I gave you can be continuously upgraded, and you can really upgrade to the heaven-level exercise in the end, and when your strength reaches the end, I will teach him to you, of course, you don't have to worry about anything else, even if I die, these swordsmanship will become your memory, and it will automatically teach you." The Yun family said again.

Listening to what the Yun family said, Yun An was shocked in his heart, this swordsmanship can still be upgraded, and every change is an increase in his corresponding strength.

If your strength increases, then a new sword technique will come out.

"Thank you!" Yun An thanked the Yun family from the bottom of his heart.

"You're welcome, I have a request for you, so I can only go all out to teach you, if you can't be strong, then who else can I teach, there is no point in teaching these!"

"Uh-huh!" Yun An continued to go all out in the next few days to familiarize himself with the newly acquired swordsmanship.

In the Demon Beast Mountain Range, a teenager kept chasing the fleeing beasts below.

Dozens of beasts were running and looking back in great panic, there were hundreds of them.

When they met Yun An, they originally thought that it could become a delicacy, but it turned out that they hadn't eaten it yet, and Yun An directly activated the sword array over there.

To be exact, it is the swordsmanship formed by the "One Hundred and Eight Swords of Demon Slashing", which is full of more than a hundred swords, and attacks them at the same time.

As a result, dozens of beasts died at once, and the beasts were extremely shocked, and some of the beasts also had the function of speaking, and they were about to evolve into demon beasts, but Yun An's attack directly broke their defenses.

"Mom, the master of the Jindan period!"

"Then what are you waiting for, hurry up and run." Countless beasts were running in front, while Yun An in the back continued to fly in the sky, and his mood was much better at the moment.

The growth of the Jindan period is not only the internal force, but also the most important thing is that the flight speed has reached a higher level.
