At this moment, the speed of the imperial sword is not much faster, it is still several times that of before, but after half an hour, it still came to the mass grave five hundred miles away. Dong Yichen looked at the sky in the distance, only to see that the sky was still clear behind him, the wind and the sun were beautiful, and when he got there, it was still covered with dark clouds, faintly full of lightning, and the miasma surrounded a radius of more than three hundred miles, and Hengyuan Tangting Mountain was only a range of dozens of miles.

"I heard my father say...... This used to be a lively and prosperous city, called Decheng. However, it suffered a natural and man-made disaster, and tens of thousands of living beings were buried here, resulting in thousands of years of yin and energy. Dangerous ...... Isn't it just a Hengyuan Tangting Mountain that can be compared? Yun Yanrou said.

Dong Yichen deeply felt Yun Yanrou's nervousness and fear at this time, because her nails were still about to grab her shoulders, and she was helpless for a while, she was obviously afraid of dying, but she had to follow alone, and then turned around and held her hand tightly, and said, "Don't be afraid, I'm here! Get ready...... We're going to break in!"

The black gas of the mass grave is flying unscrupulously, those guys who are scurrying around are the yin spirits, and the faint howling sound, which makes people sweat all over the body, the yin qi is only heavy, so that the sun can not shine, people are still far away, but they still smell a foul smell, at this moment the two are still close to the two hundred miles of the mass grave, at this time it has been completely isolated from the outside world of the sunshine aura.

Yun Yanrou had already experienced shortness of breath and a dull feeling in her chest, and then hurriedly mobilized her whole body to resist. "Make a pact with me...... Otherwise you'll die!" Ling Changji's voice suddenly appeared.

"I ...... I can. Yun Yanrou just said resolutely, in her opinion, there are still many unknowns behind the contract with her, in case of a little accident, she can't afford it, if she is another identity, it's okay to say, but she started the blood spirit clan thousands of years ago, and once this Kyushu continent was in a temporary predicament because of them.

Dong Yichen naturally felt the weakness in her body, she had a purple bead breath to protect her body, plus the fire spirit vein was already like a spirit vein, both of which could resist this evil miasma, not to mention that her current strength was in the Ten Thousand Spirits Realm. Yunyan is not more than a big spiritual realm, and there are no extra treasures to resist,

While the palm of her hand was constantly transmitting aura for her, she hurriedly took out the star copper from the space ring with one hand. Star Bronze is one of the materials used to create the Wheel of Destiny.

"Girl...... Hang this bronze-stellar around your neck!"

Yun Yanrou first felt a warm current in her palm, which was the breath in Dong Yichen's body, a powerful and reassuring power. Looking at the star bronze he was holding in his hand, this star bronze was still indomitable even in this miasma place, exuding dazzling starlight, although it was only the size of a fingernail, but after all, it had been condensed for thousands of years. Then he hung it around his neck, and in an instant, the oppression caused by the huge miasma was still much gone, and even a thousand words of gratitude at this moment only turned into an indifferent smile.

Dong Yichen is also full of admiration and spoiling, "evil girl...... Hold it steady, it's about to land!" Yun Yanrou heard this, and hurriedly grabbed it tighter.

Then the two of them landed, the surrounding area under the mass grave was dark, as long as you took a slight breath, you would feel as if you had eaten a dead mouse, there was also a jungle here, but they were all trees without leaves, the trees emitted a strong stench, and there were many corpse birds on the trees like cow hair, even if it was a long time...... There will still be some new corpses here.

In this dimly lit environment, the stars lit up the road ahead, and in the blink of an eye, they saw corpses all over the ground, still rotting. The whining and howling of the wind through the narrow cliffs made this horrific mass grave feel a little more permeating. Yun Yanrou didn't care about any demeanor at the moment, and hugged Dong Yichen's arm in embarrassment, even though she was very scared, she also accompanied him.

"Girl, don't be afraid!" Dong Yichen turned around and touched her delicate face, to be honest, he was a little scared in the face of this environment.

"You...... Say something. Yun Yanrou shouted with a slight tremble, and if she didn't have such an environment, she couldn't feel how safe that hateful person was. Dong Yichen also smiled helplessly, maybe only in this environment could he see Yun Yanrou's panicked appearance, and muttered: "The mass grave is big...... I wonder where the underground palace is?"

"I ...... I do not know. Let's look around!" said Yun Yanrou tremblingly. Dong Yichen just clenched his hand helplessly, and gave her the power of the light like a spiritual vein, and Yun Yanrou was not trembling for a while, "Hold on to me, don't get lost!"

The sound of babbling wailed all around.

Boom!

There seemed to be several figures behind him, and I didn't know if it was a human or a ghost, or a livestock. Then the two of them also quickened their pace, and slowly walked inside, although it was a miasma place, but there were still a lot of withered yellow withered grass, and the withered grass still almost submerged the two people, just holding a sword in one hand and slashing at the grass.

The two of them walked aimlessly, and they didn't know how long, and they couldn't feel the time in it, and the boundless darkness made people breathe short. The sound of the wind swishing was accompanied by a rustling sound.

Flutter.

"Who?" Dong Yichen turned around and looked at vigilantly.

But there was only the sound of the wind.

"You...... Did you find anything?" asked Yun Yanrou.

Dong Yichen smiled slightly: "No...... No, I guess I'm overthinking!" he just lowered his head, his attention still behind him.

Suddenly, there was a strange sound behind it. Dong Yichen just pretended not to hear it, because he still felt a lot of breath slowly approaching, and walked for a long time, and the sword in his hand was ready to swing out at any time.

Da-da-da-da.

Rustle.

Dong Yichen squinted slightly, and the sword he held in his right hand was still thrown out, hmph! The blazing flames of the Holy Spirit Sword were particularly dazzling in this pitch-black mass grave, and when he looked at it in a blink of an eye, he found that the sword was on a cloud of black gas, and as soon as his mind moved, the sword turned around and stabbed at another black gas, and the two black gases disappeared in an instant. "Run!" Dong Yichen noticed that something was wrong, so he hurriedly pulled Yun Yanrou and ran, "What's wrong?"

"I feel a force approaching us, be careful not to get into your body by those black gases, or you will be controlled!"

The sound behind him was also constant, and the two yin spirits that were killed slowly turned into four, eight, and sixteen, and they split more and more, and a cloud of black qi was raging after the two. Dong Yichen would be cut in half with just one sword slashing out those breaths, but no matter how he scattered them, the final result would only increase.

"They...... Why can't they finish killing them?" shouted Yun Yanrou.

"Silly, this is a mass grave with boundless yin qi, how can it be killed?" Dong Yichen said, just feeling that the purple beads in his abdomen seemed to be struggling, and the three dark purple beads wanted to resist, and wanted to absorb the yin qi like when they were in Hengyuan Tangting Mountain. At this moment, the power of the red and purple beads is still strong, plus his heart has long been no longer with Gu Tianmo, Jun Hao suppressed it to death, if it is broken free, it will not be fun.

But not long after they ran, the two of them were wrapped in those yin spirits. "Stubborn, is it really a young master who can't do anything about you?" Dong Yichen said, just stretching out his right hand, and a dazzling light was emitted, and the appearance of this light Those Yin Spirits who did not cultivate enough were directly wiped out by it. "You...... When did you cultivate the light like a spiritual vein?" Yun Yanrou said curiously.

"Yesterday night. But...... The effect of this light like a spiritual vein on this kind of yin is really good!" Dong Yichen was a little proud, and finally left the weeds jungle, but he didn't expect that there was a swamp outside this weed, so he simply dragged Yun Yanrou in time, otherwise, ...... It's not fun to fall, but the swamp is about thirty feet wide.

"What now?

"Girl, has your IQ also been sealed by this mass grave? It must be the past of Edgeworth! What's more, isn't your light skill very good? There is so much driftwood on it!" Dong Yichen said, and put the Holy Spirit Sword in front of him, but he didn't expect that just halfway through the flight, a figure suddenly appeared in front of him, and he was kicked off the sword before he could see what this thing looked like.

The two were just taken aback.

Yun Yanrou reacted in time, turned forward, spotted a wooden stake, and planned to jump over it. And at this moment, the stake was shattered by the black shadow, and it was about to fall into the swamp without focusing for a while. Dong Yichen suddenly rushed over, hugged his thin waist, stepped on a skeleton again and again, jumped and jumped out of the swamp, but suddenly a black aura split into the air, the two were forced to separate, Yun Yanrou fell into the swamp, no matter how hard her feet worked, she couldn't move, she could only watch herself slowly sink down.

Dong Yichen was kicked onto the grass, and a backflip also stabilized his footing, and hurriedly shouted: "Don't move!" As soon as the words fell, two figures rushed over again, and when they saw this, they just hurriedly retreated. The fists of the two figures smashed to the ground, and the ground was directly slammed away by the swift fist.

At this moment, I can see their faces clearly, they are actually skeletons, one tall and one short, they have no flesh and skin, and they are wearing black robes, and the same is true for the two. "Skeleton man?" Dong Yichen was slightly surprised, he didn't expect this skeleton to be able to move, not only is his strength not low, but the two of them together can at least be comparable to the master of the Ten Thousand Spirits Realm.

One of the tall skeletons held in his hand what looked like the loin behind the human bones, and the bone sword was about three feet long, and the whole body was white. I saw him striding with a bone sword in his hand, and with a swing of the sword, he howled and screamed, a deafening ghostly sound. Seeing this, Dong Yichen hurriedly turned his body to the left slightly, at this time he needed to solve them quickly, otherwise Yun Yanrou would be completely trapped in the swamp, and when he turned around, he held a spirit seal in his hand, which seemed to be hitting the taller skeleton man, but it was actually hitting the short skeleton man not far away, and immediately a golden and white formation rippled out under the feet of the short skeleton man, and a light prison appeared immediately, trapping it.
