In the vast dead air, Nie Fan and Nangong Yeming cautiously walked towards the depths of the valley, surrounded by a thick and deep dead air, completely unable to distinguish the direction, and these dead qi contained a strong sword power, even the power of spiritual ideas can be completely isolated, Nie Fan's Heaven and Earth Changing Dafa can only reach a distance of two zhang, so he is powerless.

This is an astonishing data, you must know that as Nie Fan's cultivation has deepened, his sea of knowledge has also grown amazingly, and the power of his spiritual intent has skyrocketed, and now the Dafa of Changing Heaven and Earth has been able to envelop a radius of hundreds of miles, which shows how thick the sword death qi in this Burial Sword Valley is.

Fortunately, Nie Fan had buried the spiritual imprint on Sun Da's body before, as long as it was no more than a thousand miles, then Nie Fan would be able to find Sun Da following the trajectory left by the spiritual imprint, so he didn't worry about getting lost in this sea of dead air.

"Nie Fan, this place seems to be a bit weird!" Nangong Yeming looked at the gray dead air that was constantly rolling around and said, "How do I feel like we've been circling all the time?"

"That's right, we are indeed not walking in a straight line, but going around and moving forward!" Nie Fan looked at the faint edge of the sword in front of him, and said in a detour: "It should be some trap in this fog, the one before us only went around, it should be something like a forbidden formation, and my Heaven and Earth Transformation Dafa can faintly feel the threat coming from ahead." ”

"Oh!" Nangong Yeming nodded, and on the way, Nie Fan told him the mystery of the Dafa of Changing the Heavens and the Earth and the part of the involvement with Sun Da, and there was also some faint speculation. At this time, he asked just to get a positive answer from Nie Fan.

In this way, without saying a word all the way, the two of them kept changing directions in the direction of Sun Da's advance, moving forward in this vast sea of dead mist, constantly avoiding those faint forbidden traps on the road.

Fortunately, thanks to the guidance of Sun Da's spiritual imprint, Nie Fan and the others were able to avoid countless dangers, and even after the two of them bypassed and avoided several large formations, even Nangong Yeming, who was completely suppressed by the power of his spiritual mind and could not leave his body, could faintly feel the danger hidden in the sea of fog.

This also made them secretly glad that Sun Da led the way, otherwise. Even if the two of them are strong. It is estimated that it will not be able to survive these bans without a little injury like now, and a lot of time will be wasted.

Time passed like this, and Nie Fan and the two of them walked all the way to stop and stop, twisting and turning, and quickly walked through the sea of dead qi all the way, just when Nie Fan and the two were ready to follow the spiritual imprint on Sun Da's body all the way to the depths of the Burial Sword Valley. Ao Bai, who had been recuperating in his sea of knowledge, suddenly spoke.

"Nie Fan boy. Are you really going to just go all the way down like this?"

"Huh?!" Nie Fan was stunned. Standing still, he knew that Ao Bai would not be without purpose, and now he must have something to tell him.

"Nie Fan, what's wrong?" Nangong Yeming behind him saw that Nie Fan suddenly stopped and was silent. Pressing the hilt of the long sword with his hand, he asked vigilantly.

"I don't know! Dafa faintly felt a sense of threat coming from ahead!" told Nangong Yeming that Ao Bai was dead, and at this moment, it was naturally difficult to say that Ao Bai's speech made him feel faintly bad, so he made up another set of rhetoric.

It's not a deception, he did feel a faint sense of threat from the sea of fog in front of him, but the feeling of this threat was very weak, and he was in the blind obedience to Sun Da's route before, and he didn't detect this warning in time, but he was a little lax.

"Huh?!" Nangong Yeming was stunned when he heard this, and then thought of the key point: "Did Sun Da also pass through the front?"

"Hmm!" Nie Fan nodded heavily, and then shook his head: "It shouldn't be that Sun Da discovered something, but that this layer of fog should have been crossed like this, and Sun Da was able to come and go to this layer of fog so freely, he must be very familiar with this layer of fog, and it is likely that he has some kind of token to pass this layer of fog!"

Nangong Yeming nodded, this is the most reasonable explanation: "Can you go around and avoid it?"

"I don't know, you can give it a try!" said that, Nie Fan didn't have great expectations for this method of detouring, since Sun Da chose to go through directly, it means that there is only one way to go through directly or the most efficient way to go through this place.

Nie Fan had more expectations for Ao Bai in his mind than going around, and this old guy must have seen something.

"Senior, do you already know the origin of this sea of fog?" Nie Fan asked respectfully in the middle of the sea of knowledge.

Ao Bai didn't answer Nie Fan's question immediately, but asked with interest, "Oh, how can you be sure that I know the origin of this sea of fog?"

Hearing this, Nie Fan was reassured: "Since the seniors questioned the juniors before, then they must have a certain understanding of this secret realm in their hearts, please give us advice!"

"Heh, what a slippery boy!" Ao Bai scolded with a smile: "That's right, I did guess some of the origins of this secret realm, but I don't know everything, I can only say that I guessed a little!"

"According to my perception of this secret realm, if you had walked into that sea of fog by inertia so stupidly before, I am sure that you will definitely suffer a big loss, and it is unknown whether you can even save your life!"

"So serious?!" Nie Fan's eyelids jumped, although he felt a faint sense of threat coming from the layer of fog in front of him, but he didn't expect it to be so serious.

"That's right, boy, this is not my old man's alarmist! If my prediction is correct, this sea of fog should be a maze as a whole, with countless killing arrays embedded in it, and this layer of fog in front of you should be the last layer of this sea of fog maze, as long as you pass this layer of maze, you will be able to escape from this sea of fog maze. ”

Ao Bai looked at Nie Fan with a smile and continued: "And according to my guess, this last layer of the sea of fog should be the most powerful in the entire sea of fog maze, you recklessly broke into it, and you didn't have a little preparation, who would die if you didn't die?"

Thinking that he almost broke into a powerful maze like this, Nie Fan was also in a cold sweat: "Thank you seniors for your advice, so how should the juniors break into the formation?"

Ao Bai accepted Nie Fan's salute with a big grin, and said, "If you want to break into the battle, it's not difficult!" (to be continued......)

PS: If you want to break into the battle, as long as you smash the tickets down, the maze will naturally be broken
