"You're right?!" Han Yi was about to answer Xuan's words, but suddenly became confused.

"What's going on?!" Xuan sensed Han Yi's doubts.

"I seem to have been promoted!?" Han Yi said with some excitement.

"What do you mean to reach the Boundary Breaking Realm?!" Xuan was also very happy, after all, the stronger Han Yi's strength, the more powerful he could exert himself.

"Well, I've reached the realm of breaking boundaries!" Han Yi almost jumped up in excitement.

Endless life and death, endless war will, endless time and space, breaking the boundary, even if thousands of generations sleep, can not resist the footsteps of the peak, the destruction of this life, only for the return date of the next life.

"Roar, your progress is very fast, I believe that in the near future, you will definitely be able to reach the Triple Rebellion!" Xuan couldn't help but sigh.

"What!??When will I reach the Boundary Breaking Realm!" Although Han Yi was very excited, he still felt a little lost in his heart.

"Your progress has been very fast, you remember how unattainable Chen Du was in your eyes when you didn't come to the Immortal Sect, but now, I guess, you don't have any feelings for him, right? Hyun said as he encouraged.

"Okay, I'd better cultivate it first, the Yuqing Jue hasn't been fully comprehended, the demons in the Heavenly Demon Knife have all dried up, I don't think they have any action, how can they consume so much aura!" Han Yi said helplessly.

Now, Han Yi has been able to see everything that happened in the Heavenly Demon Sword through spiritual induction, and now there are nearly 40,000 demons in it, who are meditating almost every day, as if they are cultivating with humans.

However, the aura consumed every day is very amazing, and now Han Yi will cultivate the Jade Qing Jue as soon as he has time, collecting infinite spiritual energy, but once it stops, the demon begins to be a little weak, and after a long time, he will even fall, and there are a few times when he actually dies.

Han Yi was shocked at first, but after Xuan's explanation, Han Yi realized that if he couldn't get the replenishment of the aura, the Heavenly Demon Knife would drain the demonic qi of the demon, leading to the death of the demon, and if the spiritual energy in the Heavenly Demon Knife was exhausted, then the entire demon would die, and their demonic qi would be drained by the Heavenly Demon Knife.

Jade Qingjue, pay attention to the concentration of essence, the heart is clear and transparent, must have a strong spiritual strength, otherwise it is difficult to extract the aura of heaven and earth.

But now, in the underground battlefield, it is difficult to extract the aura of heaven and earth at all, but the demonic energy of the underground battlefield is soaring, so supplementing the aura with demonic qi, Han Yi has no effort, and the Heavenly Demon Knife itself will not reject the demonic qi, and even has a feeling of attraction, and now it is almost barely able to maintain the normal survival of these 40,000 demons, if the number of demons continues to increase, I am afraid it will be difficult to continue.

At this time, the demonic qi of the entire underground battlefield began to concentrate towards Han Yi, like a whirlpool, constantly whirling.

Suddenly, the Heavenly Demon Order Banner in front of Han Yi flew up, floating quietly in mid-air, revolving around Han Yi.

Han Yi's eyes opened instantly, and after stepping into the Boundary Breaking Realm, his senses were also enhanced a lot, and he was able to be more thorough in terms of discernment.

"What's going on?" Han Yi couldn't help but wonder as he watched the Heavenly Demon Order Flag float in the air.

"Roar!" Xuan roared, and an old man jumped up and down in Han Yi's mind like a child.

"What's going on!?" Han Yi asked in a deep voice.

"This Heavenly Demon Order Banner can actually mobilize the demonic energy of the underground battlefield!" Xuan roared.

"What do you mean?!"

Han Yi was still puzzled, he was like a child now, he didn't understand anything, and what he said was that he had only stepped into the immortal cultivation realm for more than half a year.

"In other words, the Heavenly Demon Order Banner is included in the Heavenly Demon Knife, as the center of the Heavenly Demon Knife's condensation, it can invisibly gather a large amount of demonic energy, which can replenish more demons and condense the body of the Heavenly Demon Knife faster. ”

Xuan said happily, as long as the Heavenly Demon Knife is condensed, he can use the Heavenly Demon Knife to re-enter the world, although it can't reach his strength back then, but after all, it is a very happy thing to be able to resurrect.

"But why is that?!" Han Yi likes to dig into the root of problems, which is why he has improved so quickly.

"This, I don't know now, but you don't care so much, as long as you can condense the Heavenly Demon Sword body, it's good for us!" Xuan simply began to get carried away.

"Okay, but you'd better figure it out, there is no protection of the Immortal Gate here, we will be wiped out if we are not careful, I don't want to die in this hellish place!"

Han Yi stood up quietly and held the Heavenly Demon Order Banner floating in the air with his right hand.

The Heavenly Demon Command Banner did not reject Han Yi, without any intention of breaking free, Han Yi looked at it coldly, he was still a little hesitant, he didn't know what would happen if he integrated the Heavenly Demon Command Banner into the Heavenly Demon Knife, but after an inner struggle, a sword shadow instantly erupted in his right hand, swallowing the entire Heavenly Demon Command Banner.

The Heavenly Demon Order Banner was instantly submerged in the Heavenly Demon Knife, and directly came to the center of the Heavenly Demon Knife, and at this time, the demons inside instantly had a trace of commotion, and they were a little afraid of the Heavenly Demon Order Banner.

Han Yi's divine sense swept over the Heavenly Demon Sword, and at this time, the spiritual energy within the Heavenly Demon Knife instantly surged towards the Heavenly Demon Order Banner like a storm.

Han Yi was stunned: "Xuan, what's going on?!"

Xuan didn't answer, but the demons inside the Heavenly Demon Knife began to struggle, began to convulse, and some directly collapsed, and the whole person was evacuated by the Heavenly Demon Order Banner.

"Roar! I see!" Xuan was silent for a long time before finally speaking.

But at this time, more than 10,000 demons in the Heavenly Demon Knife had collapsed, and now this number was still increasing, although it could not cause any substantial damage to the Heavenly Demon Knife, but this heart-pounding feeling still made Han Yi's heart palpitate.

"What the hell is going on!?" Han Yi asked anxiously.

"It's okay, the body of this Heavenly Demon Order Banner has also caused some damage, if you want to use it, you must repair it, otherwise it can't be used at all, now the Heavenly Demon Order Flag is recovering on its own, I believe that it won't be long before it can recover as before, becoming a powerful magic weapon!" Xuan smiled and soared into the sky.

"But if you continue like this, the demons will be consumed!"

Han Yi said worriedly, he is a typical little family, since it is his own, he has lost so much, of course he will be heartbroken.

"What's this, after tens of thousands of years of life and reproduction, the demons in the underground battlefield are estimated to have exceeded tens of billions, and there are many more demons in the demon world than here, so we will collect them when the time comes!"
