After this stunned effort, the green worm had already flown away, and Yu Sheng looked at the blood stains on the ground again, and followed without hesitation.

Three hours later.

Yu Sheng looked at the frog hovering in mid-air, thoughtfully, glanced at the surrounding ground casually out of the corner of his eye, squatted down, and tapped on the ground with his index finger, making a "dong dong" sound.

"Empty!" The corners of Yu Sheng's mouth curled up slightly, and his palm lightly slapped on the ground, but he was bounced ten meters away, looking at the original place in horror, frowning.

"The ground here seems to be forbidden, and with my current formation attainments, I can't even see the slightest clue......" Yu Sheng touched his chin and gradually fell into contemplation, and after a long time, he returned to the same place, his hands kept groping around, and he still found nothing with such a stick of incense.

"How so?"

Yusheng's face was low, the ground under his feet was undoubtedly empty, and judging by the performance of the frog, the early autumn must be under his feet......

"Oh no!" Yu Sheng patted his head, as if he thought of something, his face became extremely ugly, and he couldn't help but put the frog into the wooden box, and ran back all the way back according to the same way.

The frog will only choose the shortest distance to lead the way, but it can't be sure of the route that the other party has walked, at this time the other party is circling, which means that early autumn is at his feet, and there is no entrance to the ground, it can only mean that the other party entered the underground from somewhere else, and walked here, I am afraid that the previous blood stains were not deliberately left by early autumn, and what it refers to is the direction of the entrance......

Yu Sheng was clever this time but was mistaken by cleverness, this time and again, to say the least, it would have to be delayed for six hours, and he was not sure if the blood stains would be buried like footprints......

Outside the snowy region, the demon clan big man stepped into the snowy region with firm steps, and his figure quickly disappeared into the wind and snow......

When Yu Sheng returned to the same place, the blood stains on the ground had turned into red ice slag, seeing this scene, Yu Sheng finally breathed a sigh of relief, but think about it, the yin qi in this place turned into snow, and it melted when it landed, so naturally it could not bury such conspicuous blood stains, but how was it injured in early autumn?

Yu Sheng suddenly had a bad premonition, and he didn't spare his strength anymore, and walked along the bloodstains, but the bloodstains stopped abruptly in front of a snow bag.

Yu Sheng looked up and looked around, except for the white expanse, there was nothing outstanding, let alone a human figure, not even a little other color, but the bloodstains were quite strange, without any signs at all, as if they had disappeared out of thin air.

In that case......

Yu Sheng suddenly squinted his eyes, stared straight at the snow mound in front of him, stretched out a hand and poked in front of him, a surprised scene appeared, half of his palm seemed to disappear out of thin air, as if stuffed into the air.

"Is this ......?!" Yu Sheng was stunned and fell into deep thought.

I remember when I was planting Sword Mountain, Yusheng accidentally broke into a cave halfway up the mountain, and saw an incomparably beautiful scene, and the entrance of the cave, because of the natural magic and the effect of light, can only be seen from one angle......

The snow hills in this place couldn't help but make him think of a similar natural formation, but this place was obviously more perfect, and no matter how far he looked, he wouldn't find the existence of the entrance.

Yu Sheng hesitated for a moment, and finally stepped into the invisible entrance, and the flowers in front of him seemed to have arrived from one world to another, just one step away, but the scenery on both sides was very different.

What is certain is that this is an underground cave, without any traces of artificial carving, and there are crystal clear blue ice blocks everywhere, including the feet of Yu Sheng, which are also ice blue crystals of unknown depth.

Yu Sheng tentatively released his divine sense, and in an instant he was dizzy and his head was swollen, as if his head had been pricked by a needle, and he didn't dare to release any more divine sense.

"The cold aura of this place can actually invade people's divine sense!" Yu Sheng was surprised in his heart, but his eyes looked at his feet, at his feet, there was a pool of blood-red ice crystals, which only continued for dozens of steps, and it was the other party who stopped the bleeding in the future.

Now that he has found the entrance, a stone in Yu Sheng's heart has finally been put down, although there is a large space here, there is only one way in front and back, and there is no need to look for it like a headless fly.

Yu Sheng simply walked and observed the scenery on both sides of it, and one of the phenomena that caught his attention was that among these blue ice crystals, he could occasionally see some points, including the ground under his feet, and the deeper he went, the more black spots became larger and larger.

After walking for dozens of miles, Yu Sheng finally couldn't help but stop, squatted down, squinted and looked intently at a black spot directly below, and only after a long time did he suddenly move, and quickly got up and walked to a wall, and looked intently again.

"There are so many unknown demon beasts frozen in these walls and grounds!" Yu Sheng looked away, his eyes still flickering, one can imagine how shocked he was by these frozen demon beast corpses.

If it were some ordinary demon beasts, whenever Yu Sheng saw these demon beasts clearly, he always felt that those cold eyes were looking at him, and none of the demon beasts were the kind he had ever seen, and some of them made people shudder just by looking at their body shapes.

Yu Sheng became more and more convinced that this Zhong Mountain was related to the Candle Dragon, and even if it was not related, it was a forbidden place that could not be easily set foot in, and perhaps there were many secrets in it that he did not understand......

Yu Sheng had already pressed his palm to the hilt of the sword, and walked forward nervously, taking every step carefully, because he suddenly discovered one thing, is the blue ice crystal here also transformed by Yin Qi? If so, I don't know how many times more dangerous it is here than outside?

I don't know how big the underground rock crystal is, and I don't know how long it is, Yu Sheng can't tell the difference between night and day here, and he doesn't even have the concept of time, he just feels that he has walked a long, long way, but there is still no end in sight, and he doesn't know how to persevere in early autumn.

Yu Sheng counted his steps, so as not to get lost in the confused concept of time and space, which was the inspiration given to him by Cao Benshan with the timekeeping of Buddhist beads, and it was really useful to put it here.

"I wonder if the old guy has been lost......

Yu Sheng thought so, after staying here for a long time, it was easy for people to lose themselves and make some crazy moves, but at this moment, he finally saw the figure that he was thinking about.

Without thinking about it, Yu Sheng suddenly sped up, and in the blink of an eye, he had already come to the side of the figure that caught his eye, and immediately changed to a look of surprise and uncertainty.

This person was indeed in early autumn, but there was a hole in his chest that ran through his back, and there were burnt marks on the wound, and the blood should have flowed from this wound along the way......
