Mu Lao was silent for a long time, it is true that his strength in the underground has improved a lot back then, but that has long been in the past.

"Sect Master Chu, I don't know about Chen'er"

"Hehe, you can rest assured about this old man, even if I don't need to say more, that old guy will do things beautifully. Chu Yu dragged his chin and looked thoughtful.

"You mean too old?"

"Naturally, if the other two factions know that our Qingchen Sect has such a talented person, hehe, then I'm afraid the ending won't be too good. ”

Mu Lao glanced at Xie Chen, and also felt that what the other party said was right, after all, Xie Chen's talent was too demonic, and it was not impossible to reach a higher level than Taishang Lao, of course, it was just that the hope was relatively small, after all, they had been in the north for too long, so long that even Mu Lao himself had forgotten how many thousand years they had not been out of such a realm.

"Xie Chen, this is for me, it is for you personally, not from the sect, I hope you can go far on this road. Chu Yu flipped his hand, only to see that a small cyan sword suddenly appeared in it. "This sword is a human weapon, it can deliver a powerful blow that is not weaker than the Heavenly Machine Realm, and it can still play a key role in times of crisis. ”

Chu Yu said that he handed the cyan sword in his hand to Xie Chen, for him, the master of a sect, the value of a human weapon can be said to be insignificant, after all, the sect often rewards some disciples who are not weak, so his move is also to leave a good impression on Xie Chen.

"Thank you, Sect Master. Xie Chen played with the small sword in his hand, and he couldn't put it down, he didn't have a decent weapon on him, this little sword could be described as a send-off in the snow.

Bidding farewell to Chu Yu, Mu Lao took Xie Chen back to his own peak, and along the way, Mu Lao also looked at Xie Chen, a talented and demonic guy, from time to time to see what was the difference between this supreme talent and their six-star talents.

However, Mu Lao's wish was obviously about to be frustrated, and at this time, Xie Chen kept holding the cyan sword in his hand, looking very happy.

"Look at your point, an ordinary human weapon will make you happy like this, you don't know that there are heavenly weapons above the human machine, earth weapons, mysterious weapons, yellow weapons, and mysterious weapons are really earth-shattering treasures, and the human weapons in your hands are just this gadget, and they really don't play any role in the comparison above the heavenly machine realm. Mu Lao looked disdainful, he didn't expect that a guy with such amazing talent would have a soft spot for a human weapon, and Mu Lao began to wonder if Xie Chen was a lost child in a big family in the Eastern Regions before, and he would be so easily satisfied.

"Hehe, Mu Lao, what you said is not right, you also said that this thing is useless to people in your realm, but for those of us who are only in the initial realm of cultivation, it is all a treasure. ”

Xie Chen's words made Mu Lao not know what to say for a while, and the two of them arrived at the peak of the mountain with only three houses in a blink of an eye.

"Okay, you go and rest, three days later, our Dust Clearing Sect will give you talented disciples a grand prize, I hope you can break through to the Great Perfection of Body Casting in it. Mu Lao said leisurely.

Xie Chen was also interested when he heard the reward, and the fact that he had heard Mu Lao and the Qingchen Sect Master talk about the underground underworld fire before made him very curious, thinking that what Mu Lao was talking about now was this.

"Reward? I don't know what the reward is, can it really make me cultivate to a breakthrough?" Xie Chen was puzzled, you must know that he had actually tried many ways to get his body closer in Tianyu Academy, but in the end, he didn't see a breakthrough at all, but he didn't expect Mu Lao to say that there was a way to make him break through, which made him who was eager to become stronger, how could he not be excited.

"Hehe, that's nature. When the heavens and the earth first opened, there were many things that existed before this heaven and earth, such as the Nine Shadows, the Xuanying, and other unexplained territories. ”

"Nine Shadows, Xuan Ming?" Xie Chen felt that his brain was a little insufficient, he had never heard of this.

"Naturally, you don't know, if it weren't for the fact that our Qingchen Sect has such a place, I wouldn't have known that there is such a mysterious place in this world. ”

Before Xie Chen could continue to ask, Mu Lao continued: "Nine Immortals, Xuan Ming is an extremely special place in this world, some great powers may not be able to find it for thousands of years, but there are mortals who are inexplicably attracted to this place when they are inadvertent. The land of the Nine Shadows is the habitat of thousands of living beings, there are no living creatures, there is no life, and the legend says that as long as everything related to the Nine Shadows is contaminated, then this person will soon mysteriously disappear from this world without a trace. And the place of the underworld refers to places that people can't understand with common sense, and I have never heard anyone describe all kinds of things there, because no one can come out of whoever goes in. ”

"Could it be that there is one of these two places under the Qingchen Sect?" Xie Chen was a little surprised, Elder Mu's words had already made it very clear to him that these two places were good places.

"How is this possible, if that's the case, my Dust Clearing Sect won't be like it is now, it has long been a land of ruins. ”

"What Mu Lao said is this" Xie Chen was a little puzzled, since he didn't, Mu Lao still said it in such detail.

However, Mu Lao's later words made Xie Chen understand that the origin of this so-called dark fire was not very simple. "Back then, a disciple of our Qingchen Sect somehow accidentally broke into a cave on a mountain peak, the cave was very long, reaching deep underground, but this disciple did not rush to go, but told the news to one of his elder teachers, and then when the elder went, he found something that existed in this condensed earth, and when the sect mobilized most of its strength, it was discovered that there was a large amount of dark fire in the depths of the earth, the kind of thing that existed before the beginning of the heaven and earth, which can make people's physical strength go further when the physical realm reaches perfection, of course, the most important thing is that when they break through to the heavenly machine realm in the future to absorb the essence of heaven and earth, the speed will be faster than that of people who have not refined the dark fire。 ”

"Then why didn't the Qingchen Sect become the first sect in the Northern Kingdom, since there are such natural conditions?" Xie Chen was a little puzzled, since it allowed the monk to have such benefits in the Heavenly Machine Realm, then the Qingchen Sect should have already been the first sect in the Northern Kingdom, why was it still the same as the other two sects.

"What you think is simple, this dark fire alone is at most refining a small wisp, and this kind of existence between heaven and earth can be used a little less. And it's only a slight improvement, and the Qingchen Sect has only allowed disciples with talents above six stars to go in previous years."

Xie Chen sighed, and then realized that this so-called dark fire was not inexhaustible.

"When the time comes, all you have to do is refine the underground fire with more energy, you know?" Mu Lao said in a deep voice. "It's about whether you can break through to perfection, and you must be up to 12 points of spirit. ”

"Got it, you won't be disappointed when the time comes. Xie Chen waved his hand and walked into his room, he cared more about his strength than anyone else, naturally there was no need for Mu Lao to say more, Xie Chen would definitely go all out.
