Xu Ning couldn't take a moment to rest, the qi in his body continued to pour out, the birds attacked too fiercely, as long as he slackened a little, he would be broken through.

Even if it is the most powerful martial vein cultivation, no matter how strong the internal force is, it will not be able to maintain a stable output for a long time. And Xu Ning had been holding on for a long time, and the corpses of the evil birds that had been swept out by the Demon Slayer Lock were piled up around the two of them, and the smell of fish was extremely strong.

It's just that the air is still overwhelming, and I don't know when I will kill.

Gradually, the original smoky chain flame light also weakened, and there was even black dirty blood dripping from the chain, it was obvious that Xu Ning's internal strength was about to be exhausted, and if he didn't do pranayama, he would be exhausted sooner or later. However, the attack of the evil bird has not weakened in the slightest, and if it relaxes, it will inevitably die in the belly of the bird.

Xu Ning can only continue to persevere, even if he has reached the end of the crossbow now.

Yan Bing didn't know how many times she had recited the incantation, and the fragrant sweat trickled down from her head, and she let out a long breath when a soft purple light met her eyes.

The purple light on the "Purple Light Night Talisman" reflected her face clearly, and Yan Bing held it between her two fingers and pointed it into the air.

Under the illumination of purple light, the demon slaying lock in Xu Ning's hand also vibrated and disordered, Xu Ning hurriedly retracted it, only to feel that the true qi in his body was clogged and his meridians were blocked.

The purple light formed a circle of light, and before the black strange birds could touch it, they all turned around and fled in panic, and returned to gather far away in mid-air.

"Works?" As soon as Xu Ning relaxed, he suddenly felt weak under his feet and sat on the ground.

Yan Bing slowly let go of her fingers, and the "Purple Light Night Talisman" suddenly flew from the tips of her fingers, twisted and rolled in the air, and then changed into countless purple talismans, shooting out in all directions, and the light was so bright that people couldn't open their eyes.

It took a long time for the two of them to open their eyes at the same time, and the surroundings fell into darkness again, the purple light disappeared, and the black shadow in the air was nowhere to be found.

The two looked at each other, still unable to believe what they had just done, and were stunned for a moment.

There was no noise from the strange birds, there was silence, only the whimpering and wailing of the dying owl in the rubble, intermittent.

"We survived!" Yan Bing said weakly, slowly walked to Xu Ning's side, and sat on the ground limply.

Xu Ning barely squeezed out a smile, he was really tired, and the purple light just now seemed to affect the power of his demon slaying lock, and said strangely: "This talisman is so powerful, it's obviously just a purple strong light, it actually dispersed these ferocious strange birds, and my chain was also shaken." ”

Yan Bing also had a blank face: "I only know that this 'Purple Light Talisman' is used to dispel illusions, but I didn't expect to save your life at a critical moment." ”

Xu Ning shook his head again and sighed: "You are really, if it were a little bit of time, you and I would have been bitten to death by life." ”

Yan Bing was a little sorry, and said: "Alas, I can't remember the spell that the patriarch grandfather taught me just now, so I can only watch those obscure words read from the script, do you know, most of these words are now lost, and I look quite struggling." ”

It can be seen that the ancient people really have their own unique skills, and this kind of talisman just now is similar to the 'Pure Spirit Talisman' that Xu Ning saw Chen Jinshi exhibiting in Zhenmo Mountain that day, but the power is obviously much stronger.

Xu Ning was about to meditate and pranayama on the spot, when there was some faint sound in his ears, which sounded like the sound of the wind, and like someone muttering in the dark night.

"It's not appropriate to stay here for a long time, Brother Xu Ning. Let's find a hidden place and rest again. Yan Bing stood up and pulled Xu Ning up, finding that he was now heavy and had no strength.

Xu Ning shook his head and smiled bitterly: "Just now I struggled to support and used my strength to eat, and I was shocked by your 'Purple Light Night Talisman', and now I am really powerless." ”

Yan Bing listened carefully this time, and was puzzled: "You will be injured by my purple light talisman like this, how is this possible?!" ”

Xu Ning leaned on her and said softly: "It doesn't matter, it's just that I was shocked, and it doesn't get in the way, this chain in my body is an unusual weapon, and the soul absorbed is also very different, probably because of mutual restraint." ”

Yan Bing seemed to understand whether he understood or not, knowing that this place was full of dangers, and there was no place to hide, so he helped Xu Ning to continue walking forward.

The cobblestone road was full of dead birds of strange birds, and the smell of fish was so bad that it was disgusting, so I had to endure it.

After holding on for a while, Xu Ning gradually eased up, so his pace quickened, and after walking for a while, he was lucky and ran along this easily recognizable pebble road.

The demon mist became thicker, Yan Bing took out the "Concentration Dew" from his arms as usual, and after the two of them smelled it, they were not afraid of the invasion of demon qi.

The cobblestone road also came to an end, and some tall buildings appeared in the fog in the distance, and the two slowly approached, and these buildings in the dense fog slowly took shape like gargoyles and appeared in front of them.

Most of the buildings have collapsed, but there are still broken buildings, like huge tombstones standing on top of tombs.

Compared to the buildings I saw earlier, this ruin is too striking, like small hills, and like a giant beast lurking in the dark.

The two looked at each other and knew that this place must be the royal palace in ancient times.

When I walked into the ruins, I felt more and more that the glory of the heyday was magnificent, there was a huge high wall that still stands, and the holes in the windows and doors were still there, as high as a dozen storey buildings, even if you look at the current Central Plains buildings, except for the towers, it is difficult to see.

After carefully passing through this high wall, which could fall down at any time, he entered an empty field, presumably this must be the square compound of the palace, and the human bones under his feet have increased, and they have to be kicked from time to time.

This time, Yan Bing stopped talking, and it was important to quickly find a place for Xu Ning to recover his body, and the bones of the dead would be put aside first, and if the dead had a spirit in the sky, they would not be blamed.

"Look!"

Xu Ning's eyes were like torches, and he pointed to a tall building not far away and said.

Yan Bing exclaimed, "That's the Underground King's dormitory, you see there's a winged serpent sign on it." ”

Xu Ning took a closer look, and sure enough, on the round vault, there was a snake-shaped shape with its wings outstretched and its head upright, which was very similar to the pattern he had seen in the corridor before.

The fog here was even thicker, and Xu Ning followed Yan Bing through the square, through the collapsed wall, and into the underground palace built thousands of years ago.

The reason why the royal palace did not collapse and is quite well preserved is because of the different materials used to build it, and the three floors are built with black boulders, which is simple and solid. Visually, the main body of this palace covers an area of no less than 10,000 square meters, and the rooms and halls are densely packed, and there are messy items scattered on the ground everywhere, and it is extremely difficult to walk.

It was also very quiet inside, and there was not even the sound of the wind.

The two of them found the spiral stone staircase that was still intact and climbed to the second floor, where the situation was slightly better, there were not so many clutter bones on the ground, and the air was much fresher.

After going around and around, he finally stopped in a corner room far from the stairs, and the windows and doors were naturally all rotten, and only a few large holes remained.

Xu Ning sat down, meditated quietly, carried the mantra of the heart, and cultivated and recuperated.

Yan Bing opened the ring space, took out the food, and ate it quietly on the side, both of them were stained with some strange birds' dirty blood, especially Yan Bing, she felt very uncomfortable at a girl's house, but now she is in the underground ancient city, full of dangers, where is there still leisure to find water to wash, so I have to endure it.

She also helped Xu Ning to be vigilant at first, but it didn't take long for her to fall asleep on Xu Ning's lap in a daze, she was tired and scared just now, but now she relaxed and fell asleep.

Xu Ning meditated in the dark, and after two hours, he had fully recovered.

As soon as his body moved, Yan Bing was awakened, and he sat up straight like an electric shock, his dark eyes kept rolling.

"Did I die of sleep?" Yan Bing said to herself, like a whisper in a dream.

Xu Ning was noncommittal, took food from her arms, and ate it.

"I fell asleep to death?" Yan Bing stretched his waist and yawned. Smelling the fishy smell emanating from the two of them again, he hurriedly took out the potion and dripped it on the handkerchief, I sniffed it with Xu Ning.

"What's next?" Xu Ning asked, since the two fell in love, he had become unassertive and inert.

"Of course, I'm looking for the 'Soul Searching Furnace'." Yan Bing propped his chin with his hand, thoughtfully, "Let's turn the bottom in this palace first, if not, then find another way." ”

Xu Ning looked embarrassed and said, "However, there are no less than two hundred rooms on this floor, and if you look carefully, a few days will not be enough." ”

Yan Bing smiled, and quickly covered his mouth with his hand, for fear that the movement would be too big, and said in a suppressed voice: "Fool, I teased you, how could this stove be hidden here, I slept just now, and in my dream I faintly felt that the stove was definitely somewhere else." ”

Xu Ning's face changed greatly when he heard this, and he quickly asked, "Could it be that someone has stolen it from the underground ancient city?" ”

"That's impossible." Yan Bing said, "It's just not in the palace, after all, it is impossible for such an important thing to be placed in such a conspicuous place so casually." ”

Xu Ning nodded in agreement: "It's just that if it's not here, it's even more difficult to find, and I don't know how big this underground ancient city is, and finding a stove is tantamount to looking for a needle in a haystack." ”

"You don't have to look for it yourself, someone will take us there." Yan Bing's eyes flashed and he said slyly.

Xu Ning suddenly realized: "Yes, why did I forget this, I thought about luring the demon master out before I came, and as soon as the demon master appeared, the furnace was naturally nearby." ”

"You've got a good idea to lure the snake out of its hole." Yan Bing smiled, and suddenly changed his mouth again, "But it's too reckless and dangerous, I have other ways." ”

Xu Ning was about to ask a clear question from her mouth, when the demon slaying lock in her body trembled inexplicably, and she hurriedly covered Yan Bing's mouth with her hand, signaling not to make a sound!
