The two of them breathed for more than two hours, Lei Xiaotian's strength and spiritual power have all recovered, and they have improved slightly, after Lei Xiaotian stopped pranayama, he saw that Nangong Ling was already waiting for him next to him, and then said politely to Nangong Ling: "Miss Lao Nangong has been waiting for a long time, let's go in." ”

Hearing Lei Xiaotian's polite words, Nangong Ling pouted, and said politely a little unhappily: "You are really, we are so familiar with each other, just now it can be regarded as living and dying together, why are you still so polite? I call you Brother Murong, you can just call me by my name, otherwise, my grandfather and father and mother both call me Ling'er, and you can also call me Ling'er." I'll call you Brother Murong, is that good. Saying that, Nangong Ling also curled her lips cutely.

Looking at Nangong Ling's cute appearance, Lei Xiaotian smiled slightly, and replied in a kind manner: "Okay Ling'er, let's go in and have a look, but you have to follow behind me, be careful, and the matter of my demonic and martial arts double cultivation, you can't tell anyone, not even your closest relatives, you just know it yourself, it's a secret between the two of us." After saying that, Lei Xiaotian stood up and walked towards the stone gate, ready to open the stone gate.

At this time, Nangong Ling's voice came from behind and said: "Brother Murong, I know the severity, I will definitely keep the secret for you, the rotten wood will be destroyed by the forest wind, although your current strength is already very strong, if people know that you are a demon martial arts double cultivator, there will definitely be someone who is not good for you, Ling'er still knows this, I will not say anything, you can rest assured!" Saying that, Nangong Ling followed closely behind Lei Xiaotian and walked towards the stone gate.

After listening to Nangong Ling's words, Lei Xiaotian smiled at Nangong Ling and said, "Thank you Ling'er, let's go, let's go in!" When he said this, the two had already come to the stone gate, this time Lei Xiaotian stretched out his hand, first put up a protective shield on his body, and protected Nangong Ling behind him, then carefully stretched out his finger and pressed the red button on the door, and at this time, the golden words on the stone door had long disappeared, and sure enough, Lei Xiaotian's hand pressed lightly on the red button, and saw that the stone door slowly separated to both sides, and made a huge sound of surging organs, after the stone door was opened, Lei Xiaotian found that there was a long passage in the door, and there were stone walls on both sides of the passage, there was no other way out, the passage was arc-shaped, and it gave people the feeling that it was constantly declining, I don't know where it leads, Lei Xiaotian no longer hesitated, so he pulled Nangong Ling behind him with one hand, and Ling took out the streamer sword from the space ring, held it in his hand, and walked into the stone gate with vigilance.

After entering the stone gate, Lei Xiaotian did not find any danger, but Lei Xiaotian did not dare to slack off, and then pulled Nangong Ling while guarding, and moved forward carefully, the two walked for a long time, and they couldn't walk out, and there was no danger, Lei Xiaotian could obviously feel that the passage was circling, but it had been going down slowly, Lei Xiaotian estimated that he had gone deep into the ground at this time, and the vertical distance was one hundred meters away, and the passage continued to extend, but Lei Xiaotian was more cautious, and he was always on guard while moving forward carefully。

After walking for a long time, Lei Xiaotian found that there was a bright light not far in front of him, Lei Xiaotian knew that the two of them should have walked to the exit, and then sped up a little, sure enough, just after walking for a while, Lei Xiaotian found that a stone cave appeared in front of him, the stone cave was open, Lei Xiaotian knew that this must be the exit, Lei Xiaotian pulled Nangong Ling to the exit quickly, Lei Xiaotian first adjusted his true qi, ready to shoot at any time, and then stepped out of the passage.

Lei Xiaotian and Nangong Ling finally walked out of the passage, but saw that they came to a stone room, the other end of the stone room is obviously a stone door, exactly the same as the stone gate seen in the thunder and lightning space, but there is a behemoth lying on his stomach in front of the stone gate, Lei Xiaotian and Nangong Ling both know this behemoth, it is a fire dragon, the dragon wings hang down, lying on the ground and closing his eyes, as if sleeping, the whole body will be tightly blocked by another stone door, from the size of the dragon, this should be an adult dragon, the dragon is the most powerful monster in this world, as soon as the dragon egg comes out, there is the strength of a sixth-level monster, an adult dragon, generally at least an eighth-level demonic beast, with a little cultivation, it is a saint-level demonic beast, or even a divine beast.

And now Lei Xiaotian's strength is only at the level of the Great Dou Ling, which is equivalent to a sixth-level demonic beast, and Nangong Ling is just a junior magician, at most it is equivalent to a fourth-level demonic beast, with the weak strength of the two of them, when they encounter an adult dragon, it is certain death, Lei Xiaotian's head began to break out in a cold sweat, and then whispered to Nangong Ling: "Ling'er, this time it's troublesome, that giant dragon is at least an eighth-level demonic beast, with the strength of the two of us, it is a hundred, and it is not the opponent of this dragon." ”

At this time, Nangong Ling whispered to Lei Xiaotian: "I heard my grandfather say that the bigger the size of the dragon, the stronger the strength, this dragon looks more than ten meters long, five or six meters high, it is estimated that it is at least the peak of the eighth level, and even the nine-pole demonic beast, my grandfather has an eighth-level wind dragon as a mount, I have seen that dragon, it is not as big as the dragon in front of us, so I feel that the power of this dragon is definitely not as simple as the eighth level." ”

Listening to Nangong Ling's words, Lei Xiaotian sighed and said: "The predecessor who left this tomb is really powerful, he actually used an eighth-level dragon to guard the door, where can we break in, I think we can leave quickly while the dragon has not woken up!"

After Lei Xiaotian finished speaking, he immediately pulled Nangong Ling to exit the stone room and return to the passage, Lei Xiaotian knew that with the strength of the two of them, if this giant dragon woke up, the two would definitely die, but Lei Xiaotian looked back and was directly dumbfounded, because Lei Xiaotian saw that the passage that he and Nangong Ling walked into had disappeared, at this time Lei Xiaotian secretly complained in his heart, and then said to Nangong Ling: " It's too bad now, this senior is really thoughtful, stay and test, it's simply to open the bow and don't turn back, either pass the test, or die here, there is no way back at all, just like the last time, you woke up from the illusion, want to return to the fog channel, but can't go back at all, now the passage behind us is blocked again, it seems that we can only take advantage of the fact that the dragon has not woken up, quietly bypass, open the stone door behind may have a chance to pass, or die. ”

Nangong Ling was just about to speak, when she saw the giant dragon move slowly, and then opened her eyes.
