The improvement of the realm made Nie Fei gradually see the simplicity of the swordsmanship he had cultivated before.

"Although the original swordsmanship is good, but after all, it is simple, and the swordsmanship is simple, and the power it exerts is a lot lower, maybe now I think my swordsmanship is perfect enough, powerful enough, but with the improvement of the realm and vision, the current swordsmanship may also be considered simple in the future. This is Nie Fei's latest realization, just a momentary exercise, Nie Fei has a feeling of sudden enlightenment, and with the emergence of this feeling, Nie Fei's stable realm has improved again.

In this year, the demon plague still kept stimulating Yang Li with various poisons, making him feel painful, and then rescuing him, maybe after experiencing too much poisonous stimulation, Yang Li's will gradually condensed like a knife, and in the end, even if the body pain was a hundred times stronger than before, he still stood there, as if nothing had happened.

Inside the Qingquan Sword, looking at Yang Li's state, Nie Fei absolutely admired Yang Li, this apprentice was too hard, so powerful in pain, just biting his lip and standing there proudly, the trembling of his body made Nie Fei look a little distressed.

However, Nie Fei was also thinking, with Yang Li's cultivation state, if he really entered the Demon Dao, then he would still be his opponent?

Of course, while Nie Fei was observing Yang Li, the most time he spent was cultivating within the formation created by Yang Xun'er.

Yang Li could see that the demon plague really regarded Yang Li as an apprentice, during this period of time, in addition to guiding Yang Li's cultivation, he was also guiding Yang Li's cultivation, and the original state of wandering around harming people was completely gone, and it could be said that all his efforts were condensed on Yang Li's body, which made Nie Fei's nervous heart completely relieved, and he knew that he could concentrate on cultivation again.

In fact, cultivating the method of the immortal realm in the demon realm made Nie Fei's improved realm even more different from the simple cultivation of the immortal realm, Nie Fei didn't know what the consequences would be, but he could feel that the speed of cultivation progress in a specific environment was advancing by leaps and bounds, in order not to be distanced by his apprentices, Nie Fei also entered the realm of hard cultivation.

Probably because of reading the scriptures, Nie Fei and Yang Xun'er's hearts were also quieter and calmer than ever, and they gradually entered the realm of selfless cultivation.

Within the formation, spring went to autumn, summer solstice and winter had been cultivating for three years, and Nie Fei and Yang Xun'er finally woke up when the formation was broken.

Nie Fei opened his eyes, he could feel the abundance of immortal power in his body, and his sense of the sword was even more keen, and Yang Xun'er also had the same feeling, not only did her strength reach a new realm, but at the same time, in the past three years of penance, she had formed a divination formation in her mind that could deduce the changes of events, and many things could be deduced by the deduction in her mind without throwing divination coins.

"Three years is not a long time, Nie Fei's realm has been raised to the state of the nineteenth layer, but for those cultivators who have cultivated for hundreds of years and it is difficult to soar to the first level, this speed is not something that can be described as terrifying.

"How about creating another formation?" Nie Fei asked.

"Wait a minute, I'll see what's going on lately. Yang Xun'er felt that something was about to happen in the depths of her mind, and she began to deduce.

After a while, Yang Xun'er's face changed greatly, and she said directly: "Quick, Sister Zi Yan is in danger on the seventeenth floor of the Immortal Realm! ”

"What. Nie Fei's face changed greatly when he heard this, and he immediately summoned the Smurfs.

"Quick, hurry up and find Zi Yan, there's a problem on Zi Yan's side. Nie Fei commanded.

"Yes!" For Nie Fei's instructions, the Smurfs directly followed, and flew directly towards the outside of the Demon Realm under the control of Nie Fei's divine sense and the Smurfs.

"Whoosh. The Qingquan Sword turned into a streamer of light and flew towards the outside of the Demon Realm.

When the demon plague was looking at Yang Li who was cultivating, he suddenly felt a fluctuation in the space, and then looked at it and found that the Qingquan Sword next to him was actually flying outside?

"What's the situation?" Demon Plague's body moved, and he quickly tracked down his Clear Spring Sword.

"Master, wait for me. Yang Li was also very anxious when he saw it, he was worried that the master would find something, so he also stopped directly from the state of cultivation, and then followed the flying figure of the demon plague closely.

"What are you doing with you?" Demon Plague noticed that the sword had left so fast that he had disappeared from the Clear Spring Sword in mid-air.

"Isn't this helping you chase that sword?" Yang Li said.

"Hmph, with you chasing, it's a waste for you to suddenly interrupt today's cultivation time while you're still cultivating, and besides, the speed of the sword flying is so fast that even I can barely find any trace of him, how can you find it?" Demon Plague said as he used his mana to completely seal off the entire Demon Realm, he didn't believe that under the effect of his mana, the sword could escape anywhere.

Sure enough, when the Qingquan Sword flew to the boundary of the Demon Realm, it was immediately given by a powerful magic force and couldn't move.

"The demon plague is strong, we can't get out. The Smurf's face also changed greatly, and he couldn't help but say nervously.

"My strength has reached the peak realm of the nineteenth layer, can't it?" Nie Fei didn't believe in evil, and directly urged his immortal power to the extreme, preparing to control the Qingquan Sword to fly away.

"No, this is the territory of the demon plague, he has basically controlled the entire nineteenth layer of the territory now, if we boldly use mana, not only can we not open this demon realm, but we may also directly provoke the demon plague, when the time comes, if he discovers the mystery inside the Qingquan Sword, if he strikes in a targeted manner, I am worried that he will not be able to protect it." Smurfs said.

"What then?" Nie Fei was very anxious now, he was in a hurry to go out and save Zi Yan and them.

"Hide it now, I'll figure it out later. The Smurfs' mind was racing, trying to figure out how to get out.

"Master, how could this sword fly?" Over there, Nie Fei and the others thought about how to escape after discovering that the space was bound, and here Yang Li asked about the demon plague that they were searching everywhere.

"It may be that the sword spirit has been generated, so this treasure is very likely to be used by me, haha. "The Demon Plague was extremely happy, which meant that if he subdued the sword spirit, he would be able to understand the true attributes of the sword after he couldn't see through the inside of the Qingquan Sword.

Let's not talk about anything else, but the Qingquan Sword, which he couldn't break, was stronger than any weapon he had ever seen, and now that he had a sword spirit, it was definitely a divine weapon.
