Nie Chen saw that Xu Cheng's expression was very mysterious, and there seemed to be a hint of smugness, so he asked curiously, "Where is it?"

"Good place, hehe, you'll know when you go with me. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info "Xu Cheng said in a mysterious way.

"But I can't get out, and if I find out, I'm afraid it will be a bit of trouble. Nie Chen was a little difficult to ask, he was still in a tight period, and there were still twenty days before he could get out of this phaselessness, if he rashly followed Xu Cheng at this moment, I was afraid that he would inevitably be arrested and locked up for a few more months.

"Hehe, you come with me. Xu Cheng didn't say much, just walked straight towards the depths of Wuxiangd.

Nie Chen followed closely.

Wuxiang D is hundreds of meters deep, and when the two of them walked nearly 100 meters inside, it was already pitch black, Xu Cheng took out a fire fold from his body and polished it, and D was suddenly illuminated by the dazzling firelight.

Nie Chen looked to both sides and found that the depths of this phase were not simple, there were traces left by Dao Dao swords on the stone walls on both sides, but these huge and profound traces were not directly left by weapons, but sword qi and sword qi.

Xu Cheng mysteriously said to Nie Chen: "Idol, you try to punch these stone walls." ”

Hearing this, Nie Chen casually blasted a turquoise Yuan Force towards the stone wall.

"Bang!"

After a crisp sound, there was no trace left on the stone wall!

With Nie Chen's Yuan General's fourth-rank strength, although it was a casual Yuan Force training, this power was enough to injure a Yuan General First-rank martial artist like Xu Cheng. But when this Yuan Force was bombarded on the stone wall, the stone wall in D was unscathed, which revealed a trace of strangeness.

"Huh, what a hard rock!"

Nie Chen couldn't help but blurt out.

"Try it with all your might!" Xu Cheng suggested.

As soon as Xu Cheng's words fell, Nie Chen nodded deeply, and then two earthy brown and golden spirit seeds appeared in the space out of thin air, and radiated light!

"Is this the Spirit Seed?"

Xu Cheng's eyes widened, staring blankly at this wonderful scene.

"What, how can it be two spirit seeds?!" Obviously, Nie Chen's hand had surpassed Xu Cheng's cognition.

Immediately after, the two spirit seeds were tightly entangled and fused, and after a while, a small figure with a brown body and a golden halo on his head was condensed, like a little angel, floating in the air.

"Wow......"

Xu Cheng had already lost his words, and he only had time to let out an exclamation.

Below, the little man floated towards the stone wall on the side after going around in front of Nie Chen's eyes!

"Boom!"

"Bang Bang!"

The stone wall suddenly shook, as if a giant hand held the stone D and shook violently, and then a stream of golden light swept towards the stone wall like a meteor shower in the sky.

After a few breaths, a two-foot-deep depression appeared on the roaring stone wall, and next to the depression, countless visible traces appeared on the stone wall!

But Nie Chen and Xu Cheng shook their heads at the same time, because although these traces were obviously left on the stone wall, the depth and strength were too far behind the original traces, and it was not an exaggeration to say that the gap between children and adults was not exaggerated.

"The people who leave these traces are far higher in cultivation than us!"

Nie Chen said leisurely.

"When I first discovered this stone wall, I tossed around in it for half an hour, but there was not a trace left. Xu Cheng looked at Nie Chen with envy, and then waved his hand and walked inside with Nie Chen.

"Look there!"

When he walked to the bottom of this stone d, Nie Chen was reminded by Xu Cheng to look at the latter's finger, only to see that on the top of the stone wall, there were three lines of characters written impressively, and these fonts seemed to be written by someone on the stone wall with his fingers!

With the power of his fingers, he can leave handwriting on this hard and perverted stone wall, this strength is really a bit terrifying!

Nie Chen read them in turn, only to see the words written on the left: "Leaning on the sword and laughing at Hongchen"

The handwriting on the right reads: "Cut the world with a knife!"

Nie Chen carefully discerned and found that the handwriting of these two lines of words was unexpectedly different, the handwriting of those words on the left was very smooth, like flowing water, revealing an ethereal dust, while the handwriting on the right was a golden iron horse, full of domineering!

But the aura revealed in these two lines is proud, as if even this world is not in their eyes!

And in the middle of the two lines of words, there are four big characters written horizontally: "A smile captivates the city".

"What does this mean?" Nie Chen touched his chin and pondered carefully.

"I don't know. Xu Cheng spread his hands and raised two sharp eyebrows.

Nie Chen looked towards the five big characters of "Leaning on the Sword and Laughing at the Red Dust", and found that the strokes and structure of this font seemed to have been seen somewhere, thinking of the martial arts he had learned in the Sword Sect Library, Nie Chen found that these strokes seemed to have some connection with those sword moves, and those words seemed to contain a sword intent......

Standing there and studying it carefully for a while, Nie Chen faintly had a hint of enlightenment, but this realization was too profound and too mysterious, like a gust of wind, you obviously felt its existence, but it was difficult to grasp it, stretched out your hand, it slipped away from your fingers, Nie Chen simply stopped meditating, anyway, there will be time to slowly comprehend in the future.

Then he turned around and asked Xu Cheng, "This is the place you brought me here?"

Who knew that Xu Cheng waved his hand even more mysteriously, and said excitedly: "The place I want to take you to is still far away, this is just a gate leading there!"

As he spoke, Xu Cheng touched a raised stone at the bottom of the stone, and then twisted his right hand, and with the sound of "boom", a stone door more than a foot wide suddenly opened, and a more hidden secret passage suddenly appeared in front of Nie Chen!

"Where does this secret passage lead?"

Nie Chen wondered.

"I don't know. Xu Cheng shook his head: "It should lead to a place far away, you follow me first." As he spoke, he walked in front and led the way, letting Nie Chen follow closely behind.

The two of them walked for about an hour, and Nie Chen suddenly found that the Heaven and Earth Yuan Qi around him was extremely rich, and the air he breathed almost didn't need to be filtered before it directly turned into Yuan Force and entered his dantian. Of course, this kind of vitality will still go through a process of condensation and condensation in Nie Chen, which is the effect of the third-layer Saint King's gathering qi.

However, such a strong Heaven and Earth Yuan Qi still made Nie Chen feel a burst of excitement, and cultivating in this place was at least three times faster than outside.

Nie Chen suddenly remembered that when he was in the Northern Liang Kingdom, Misha had mentioned to himself that this Northern Underworld City was established by Ren Fanchen, the king of Baoxiang, on a dragon vein, could it be that this place where the vitality of heaven and earth was so strong had something to do with that dragon vein?

While he was thinking, Xu Cheng, who was beside him, patted Nie Chen's shoulder again, pointed his thumb to the back of his shoulder and said, "It's nothing, follow me." ”

Nie Chen hurriedly followed Xu Cheng's footsteps, and the two of them walked forward for a thousand meters, and suddenly a vast space appeared in front of them, only to see that this space was a thousand zhang square, and there were three roads leading to three different directions, but Xu Cheng did not take Nie Chen forward, but pointed to the stone walls on both sides, his chest rose and fell violently, and said excitedly:

"What do you see here?!"
