"Lord Hui, this is only the outermost part of the underground battlefield, usually there is only one demon king stationed here, there are 100,000 demons under his command, they are responsible for resisting some people from the human world from entering the deepest part of the underground battlefield, and this time the door of the underground battlefield suddenly opened, our demon clan was summoned by the demonic energy, and the demon king here seems to have rushed out, so there should be almost no demons here!" Ling Tian explained.

"Where is the exit from the underground battlefield!?" Han Yi was most concerned about how to get out now.

"I don't know, it's been a long time since I've been here!" Ling Tian didn't dare to lie.

"What?!You don't know!?" Han Yi asked loudly.

Ling Tian was stunned, he didn't know why Han Yi was so impatient, and he had just felt Han Yi's aura, without any demonic energy, it was completely the rebirth realm of the human realm for cultivating immortals, and it was not even as good as a demon, but although he was puzzled in his heart, he didn't dare to squeak, after all, the Heavenly Demon Sword just now was not fake, and the demonic aura that passed through the sky was also very terrifying.

Han Yi walked forward helplessly, and continued angrily: "Then tell me, where are you from? Is it the deepest part of the underground battlefield you are talking about, where is it!?"

"I haven't been to the deepest part of the underground battlefield, and I'm in the middle, but each of our demon kings has their own territory, and each demon king has a big demon king to lead, and then the demon emperor leads dozens of big demon kings, and I've never heard of it before. ”

Ling Tian now told Han Yi everything he knew.

Han Yi listened to Ling Tian's explanation all the way, and at this time he finally understood why Xuan wanted to leave him, if it wasn't for Ling Tian, Han Yi might really get lost here, or meet a more powerful existence and die here directly.

Originally, he thought that with the Heavenly Demon Sword, he would be able to restrain all the demons, but Xuan reminded him very seriously that now the power of the Heavenly Demon Knife can only deter the demon clan at the level of the Demon King, and if he encounters the Demon Emperor or even the Great Demon King, he will not be able to use that kind of restraint at all, which makes Han Yi feel very lost.

Going all the way, he really didn't meet a large number of demons, just a little bit, Han Yi didn't let any of them go, and now he doesn't need to do it himself, Ling Tian may be the number one master in the entire periphery, if he comes forward, all the demons will surrender, these few demons can't see it, but as a small person, Han Yi will not waste any bit of vitality that can make the Heavenly Demon Knife more powerful.

Han Yi's divine sense gently swept over the Heavenly Demon Knife, and at this time, inside the Heavenly Demon Knife, tens of thousands of demons were nervously busy, the entire Heavenly Demon Knife was like a mountain range, and many demons seemed to be piling up an invisible array inside, and Han Yi couldn't understand it.

"Xuan, you said that you want to teach me the Jade Qing Technique, I think it's okay now, you can cultivate, and it is estimated that the door of the underground battlefield will be opened next month, right?"

Although Han Yi was a little depressed, his optimistic personality was his best side, although he vaguely guessed that such a big thing had happened, and it would be difficult for the door of the underground battlefield to open in a short period of time.

"Yuqing Jue is to condense the aura of heaven and earth, gather the essence of the sun and the moon, turn the aura of the entire universe into your own spiritual power, replenish your vitality, and let your mana be endless, and at a critical time, you can give the enemy a fatal blow!" Xuan explained slowly.

"You mean you can absorb it endlessly?!" Han Yi was a little excited when he heard this, in this way, he didn't need to condense the elixir to maintain his mana, and through the transformation of the aura, he had many advantages in controlling the enemy.

"No, I taught you the Jade Qing Recipe so that you can condense the aura of heaven and earth and maintain the concentration of aura in the Heavenly Demon Knife, so that the demons inside will not die in it because they can't get the aura, so our plan will fail, so even if you learn it now, it will be almost difficult to use it on yourself. Xuan gave Han Yihao a blow.

"Okay, that's fine, the Heavenly Demon Sword will improve its strength as soon as possible, and we will be able to protect ourselves in the underground battlefield!" Han Yi said disappointedly.

"Listen carefully, I will naturally flow into your mind through the Heavenly Demon Sword, and it will never dissipate!" Xuan finished speaking and disappeared.

Han Yi suddenly stopped and stood there quietly.

Originally, he was in an earthly yuan realm, and it was impossible to condense his divine sense, but under the impact of the Heavenly Demon Knife, his entire bloodline had been opened, and the blood of his whole body could circulate indefinitely, and even if he was condensed together, even if he was injured, he could also condense his blood in a short period of time, so as to get respite, and the channeling of divine consciousness could also make Han Yi more empty when cultivating against the enemy, and Han Yi could occupy a huge advantage in the duel of masters of the same level.

Ling Tian almost bumped into Han Yi behind him, he didn't know why Han Yi suddenly stopped, but he also stopped immediately, after all, in his heart, Han Yi Ke was an unfathomable existence, just with his disdain for the Demon Emperor, his strength should be in the Demon God ranks!

Ling Tian thought about it, and he shuddered.

Han Yi seriously comprehended the essence of Yuqingjue in his mind, and soon, his whole mind integrated Yuqingjue into his sea of knowledge, and Han Yi's spiritual sense became more clear, and he couldn't help but be overjoyed.

Half an hour passed, Han Yi finally regained consciousness, and suddenly he remembered that there was a Ling Tian behind him, and he couldn't help but be a little afraid, he actually forgot about him, if he suddenly killed himself, the consequences would be unimaginable.

"Let's go!" Han Yi walked straight forward.

Ling Tian followed closely behind him, although he didn't understand what was happening just now, he knew that this Han Yi was very mysterious, and it was not something he could provoke.

"My lord, go any further and enter the territory of the Great Demon King of Bidan!" Ling Tian said cautiously behind him.

"Oh?!"

Han Yi couldn't help but stop his steps, Xuan had told him that now the demonic energy of the Heavenly Demon Sword could only compete with the Great Demon King, and he was hesitating whether to enter his territory or not.

"Roar! This is a great opportunity!" Xuan kept watching.

"What do you want!?" Han Yi asked, he didn't want to continue to walk recklessly like this.

"One of the Jade Qing Techniques I taught you is to collect the aura of heaven and earth, and also, that is, devouring! You can devour infinite demonic qi! Your strength wants to be reminded in a short time, it is absolutely impossible! So you have to use the supreme demon dao! Roar!" Xuan roared.

"What do you say?' Martial Arts is also similar to 'Soul Formula'?" Han Yi was puzzled.
