Back in his room, Mu Yun hurriedly climbed into bed and began to work his mind to recover his true qi.

"The consumption of this 'Nine Dragons Tiangang Fire' is really not covered, this is only one dragon, I will collapse, how much true qi does it take to send out nine dragons" Mu Yun thought, and at the same time, Mu Yun also felt the importance of true qi.

"Alas, it's still not good for your own strength, it would be nice if you could store more true qi in the dantian, upgrade, break through, yes, you have to break through" Mu Yun secretly made up his mind, he must break through to the second layer of "Pure Yang Gong" within a month.

In the next few days, except for going to the back mountain to cultivate at sunrise, Mu Yun was always in his own small courtyard at other times, never leaving a step, and his cultivation was also going on all the time. Mu Yun never triggered the "Nine Dragons Tiangang Fire" again, because Mu Yun decided to test it again on the day of the breakthrough, and he might surprise himself at that time.

The days passed like this, and the time of a month was fleeting. Mu Yun's real test is also coming......

Early this morning, Mu Yun woke up from his cultivation and slowly opened his eyes, perhaps it was the credit of 'Pure Yang Gong', Mu Yun felt that his perception was much stronger than before, even in cultivation, he could feel every move of the things around him. Mu Yun got off the bed and stretched out, feeling the pure and strong true qi in his dantian day by day, not to mention how refreshing his heart was.

"Hmm, it's been almost a month since I started my own cultivation, and recently I feel that the speed at which true qi enters my body has slowed down, as if my dantian has been filled, and I can't absorb more true qi, is this a precursor to a breakthrough......" Mu Yun guessed wildly, and finally decided to ask the old man in the back mountain later, although the old man went to the back mountain every day like Mu Yun, there was no change.

However, Mu Yun always felt that the figure of the old man was becoming more and more illusory, as if he was about to disappear. Mu Yun shook his head vigorously, deciding to leave these things behind for now, and it was important to go to the back mountain for now. After washing, Mu Yun, who was neatly dressed, walked towards the back mountain, somehow, Mu Yun always felt that something was going to happen today, I hope it was a good thing.

After a while, Mu Yun came to the back mountain, and the old man was still waiting for Mu Yun there early, judging from Mu Yun's performance this month, the old man was still quite satisfied. Not only is his cultivation hard, but his comprehension is also good, but whether he is the person he is looking for or not, he has to wait for Mu Yun to really break through before he can draw conclusions.

"Senior, early," Mu Yun greeted the old man.

"Hmm" The old man nodded, signaling Mu Yun not to waste time and start cultivating immediately.

Mu Yun hurriedly came to the big stone where he usually sat for cultivation, and cultivated cross-legged.

The old man also seemed to close his eyes and recuperate, and the two of them sat cross-legged for about an hour.

After an hour, the old man slowly opened his eyes, and what made the old man strange was that according to Mu Yun's daily time, at this moment, it should have already ended, but why did it take so long today, the old man couldn't help but wonder secretly......

Just when the old man was thinking about it, a sudden change abruptly appeared, and he saw that the true qi in Mu Yun's body was overflowing crazily.

"Not good" the old man shouted and hurriedly came to Mu Yun's side, "Boy, listen well, keep the dantian, guide the true qi back, you must not overflow again, otherwise your month's hard work will be in vain" The old man said in a deep voice.

Although Mu Yun couldn't speak, he had consciousness, and he heard the old man's words, but it was not easy to channel his true qi back, now his dantian was like a big tank full of water, and if he wanted to fill it with water, how could it be possible?

"Boy, I'll tell you the truth, you are the precursor of a breakthrough, pure yang ** is different from others**, the upgrade of ** is not to increase the reserves of true qi in the dantian, but to improve the purity of the true qi, what you have to do now is to compress the true qi back into the dantian, the more compressed, the greater the benefits you will bring after the breakthrough, if you keep expelling the true qi from the body like this, it will only fall short, don't you want to get rid of the title of 'waste', don't you want to rank in the immortal class? Have you forgotten all the humiliation you have endured over the years? The old man roared.

The old man's words completely woke up Mu Yun, "Yes, what are you cultivating so hard for, isn't it just waiting for this day, now that you see that the upgrade is in sight, but you give up because you can't stand this pain, how can this work?" And have you forgotten your original intention? Mu Yun shouted loudly in his heart.

Mu Yun clenched his teeth, endured the surging pain of the dantian, and slowly guided the surrounding true qi back into the dantian little by little, and every time he compressed a trace of true qi, the green tendons on Mu Yun's head trembled, which showed how much pain Mu Yun was enduring to endure. Time passed like this, and Mu Yun gradually felt that the true qi in the dantian was not as violent as before, and the true qi was compressing it vigorously, and there was actually a little space in his dantian, which made Mu Yun very happy, and it seemed that he had succeeded.

Just when Mu Yun was a little careless, the true qi in the dantian once again raged uncontrollably, and this time almost half of the true qi overflowed out of his body, and Mu Yun's heart instantly cooled a lot.

"It's over, it's over, it's all my own carelessness, I thought that my true anger had begun to give in, but I didn't expect that 'they' were just waiting for an opportunity, I was completely fooled, and my efforts were in vain...... "Mu Yun thought in frustration.

"Drink" At this critical moment, the old man finally made a move, only to see the old man stretching out one palm against Mu Yun's back, and the other palm was slowly rotating with his wrist as the axis, as if condensing the true qi that had just overflowed. It turned out that the old man used himself as the medium to transmit the true qi, forcibly poured the true qi into Mu Yun's body, and then Mu Yun himself reintroduced the true qi into the dantian, which was really well-intentioned.

"Boy, don't give up, continue to do what you just did, hold on," the old man shouted.

Mu Yun didn't dare to think about it, and directly focused on guiding the true qi according to the method he had just done, now Mu Yun didn't dare to be careless, for fear that there would be any more accidents, Mu Yun compressed the true qi little by little, and the crisis was resolved.

With Mu Yun's concentration and the help of the old man, after about a quarter of an hour, Mu Yun finally broke through, the moment Mu Yun broke through, he felt that the true qi in his dantian was less than two-thirds at once, but the purity of the true qi was two or three times stronger than before, and this result made Mu Yun very happy. Mu Yun, who opened his eyes, felt that his whole body was soaked with sweat, thinking about the previous situation, Mu Yun still had some fears, if it wasn't for that old-timer, he might be...

After thinking about it, Mu Yun quickly got up and bowed deeply to the old man, "Thank you seniors for helping, otherwise the juniors may lose their anger."

"Forget it, it's good to break through" The old man seemed to be very weak, and said weakly, "You can quickly see if anything appears behind the first layer of 'Pure Yang Gong', quickly" The old man gasped very seriously.

"Oh" Mu Yun hurriedly flipped through the 'Pure Yang Gong' mental method in his mind, and sure enough, he saw a text at the end of the first layer, and Mu Yun clearly remembered that it wasn't before. Taking a closer look, Mu Yun was stunned.

I saw that it said "Unrelated Martial Arts, Pure Yang Nine Styles First Form - Pure Yang Devouring Heaven Finger"
