After Yu Fei rushed into the dense fog, he felt that the aura in it was not bad, and his heart was also a lot more steady, presumably there should be spiritual grass in this place.

But in this, the same as in the desert before, once you come in, you have no sense of direction, and you can only find a random direction to fly, but after flying in, you don't relax at all, and you have been paying attention to the spirit grass and the unknown dangers.

Since this is known as a forbidden area by others, there is definitely a danger, not the influence of the dense fog here.

"Alas, I'm a little bit thinking about Langlang now, if that little guy is here, it will be able to help me smell the location of the spirit grass, which is much easier than finding it myself!"

After Yu Fei came in for a long time, he didn't find a single spirit grass, and suddenly thought of Langlang, he remembered that Langlang's nose was very sensitive to spirit grass, and it would be much easier to find it with its help.

Until half a day passed, Yu Fei didn't find a single spirit grass, and what was even more exaggerated was that he was originally flying in the sky, and suddenly felt that the true qi in the dantian stopped violently, and his whole person fell from the sky.

Bang!

Yu Fei fell to the ground, splashing all the dust on the ground everywhere, but he was confused: "What's the situation?"

Immediately sensed the dantian, and found that the true qi and demonic qi were still there, but there was no way to mobilize them, which made Yu Fei even more shocked in his heart, why couldn't the true qi be used?

He quickly stood up, and was about to use his divine sense to probe the surrounding situation, but then he was even more dumbfounded, because even his divine sense could not reach out, at most he could only reach a distance of more than ten meters around him.

"It seems that the place called the forbidden area is really not simple, and it can't even use true qi and divine sense!" Yu Feipo also figured it out, presumably because of the forbidden area, his true qi and divine sense were restricted.

In other words, he can only rely on his instinct and eyes to judge the danger and find the spirit grass, and even when he encounters danger, Yu Fei can only use ordinary moves to deal with it, and he can't use true qi and demonic qi.

But Yu Fei still didn't quit, because the more this happened, the more other cultivators didn't dare to come in, and the aura here was not bad, it was very likely to find the spirit grass, the only thing Yu Fei didn't understand was, why couldn't the true qi be used here?

After looking around for a while, he couldn't see the reason, Yu Fei walked forward, but this time he was too vigilant, after all, he couldn't use his divine sense to sense from a distance, and if he encountered any danger, he couldn't take precautions in advance.

It wasn't until he walked forward for another half a day, at this time the sky had completely darkened, and the visibility was too low, Yu Fei couldn't continue to look for it at all, so he had to sit down and rest on the spot, he tried again, and he couldn't run the exercises at all.

"It's really strange, since there is aura here, why can't you cultivate?" Yu Fei raised his eyebrows, and then didn't care about anything else, anyway, he has beads, and whether he can cultivate here or not has nothing to do with him, just go to the beads to cultivate.

Ruolan, who had been following him, was in trouble, because when she was here, she couldn't use her true qi and divine sense, and she couldn't even sense the mark left on Yu Fei's body, and now that Yu Fei got into the bead, she couldn't find it.

"I heard that there are desolate beasts here, but I can't use my true qi now, in case I really encounter desolate beasts...... I'm afraid it's a lot of bad luck, where did Yu Fei go? Obviously not far away, but why can't you even see a figure?"

Ruolan said anxiously, although she had never been here before, but she had already heard from the Demon King that there was something called the Desolate Beast in this forbidden area, this thing would not be cultivated, but its attack power was very strong, if it was outside, it would not be afraid of it, but in this there the cultivators could not use the True Qi, so it was easy to be killed by the Desolate Beast.

And Yu Fei didn't know that Ruolan was coming, he counted the time and practiced in the beads for nearly ten hours, and then came out and continued to look forward, although the sky was already bright now, but due to the dense fog, the visibility was still very low, so Yu Fei's eyesight could only see a hundred meters around.

"Hey, there's really a spirit grass!"

As he was walking forward, Yu Fei suddenly sensed a stream of spiritual power, although he couldn't use his divine sense to sense it now, but his own sensitivity to spiritual power, and the spiritual power of the spirit grass was different from the spiritual energy in the air, so Yu Fei still found the spirit grass.

Excitedly walked over, and then pulled out the grass next to him to take a look, it was really a thousand leaf flower, and Yu Fei also needed this kind of spirit grass, because he wanted to refine the Pei Ying Pill, and then strengthen his Yuan Ying again, this kind of thousand leaf flower is the spirit grass for refining the Pei Ying Dan.

However, this thousand leaf flower is not yet ripe, so Yu Fei picked it and put it into the bead space, allowing it to grow quickly in it by itself.

Now that he found the spirit grass, Yu Fei had the confidence to continue searching, and he sped up his search at the moment, but when he walked a few miles forward, he suddenly saw a stone moving in front of him.

This made Yu Fei dumbfounded: "The stone will still walk on its own?"

Feeling a little strange, Yu Fei slowly walked towards the stone, after all, he could only watch with his eyes now, but when he was less than fifty meters away from the stone, the corners of his mouth twitched, and he exclaimed, "I'll go...... It turned out to be a monster!"

At first, I thought it was a stone, but when I got closer, I realized that it was actually a monster like a stone, and this thing was bare without a trace of hair, and it looked like a stone from a distance.

It also found Yu Fei, and looked back at Yu Fei violently, and when Yu Fei saw its face, his heart jumped again, the eyes of this thing were actually blood-red, with fangs like wild boars in its mouth, and its limbs were tightly clasped to the ground, which made people's backs chill.

Yu Fei subconsciously wanted to mobilize his true qi to be vigilant, after all, this thing is probably not a simple thing just from the appearance, this body shape is more than one zhang high, and it is just lying on its stomach and walking, if a person stands up, it is at least two zhang high, and the whole appearance looks somewhat similar to a wild boar, but the color is different, and there is no hair.

But Yu Fei reacted at this time, he couldn't mobilize his true qi at all, and then he had to take out the divine sword, planning to use ordinary sword moves to deal with it.

And this thing, after seeing Yu Fei, also made an attack posture, his limbs were clasped to the ground, his body was slightly arched, originally it was still looking at Yu Fei, but after seeing Yu Fei take out the divine sword, it took the lead in swooping and rushed towards Yu Fei.

Yu Fei also realized that this thing looked as stupid as a stone, but it was not slow, just a pounce, and it was in front of him, and Yu Fei took a few steps back and stabbed it with his sword.

"Whew......"

When Yu Fei stabbed it with a sword, it actually let out a scream like killing a pig, and the sound was extremely harsh, which shocked Yu Fei's eardrums painfully, but Yu Fei's movements were not slow, after stabbing it with a sword, he quickly withdrew and retreated, and this guy slapped it with one claw, shooting a pit on the ground.

"This thing has a lot of strength, and it doesn't have a trace of spiritual power fluctuations on its body, it shouldn't be a demon beast, but if it's just an ordinary animal, it's even more terrifying!"

After Yu Fei retreated, he was even more surprised, because he didn't sense a trace of spiritual power fluctuations on this thing, so since it was not a demon beast, it could have such a huge force, which was simply shocking, because the claw it slapped just now had at least a thousand kilograms of strength.

Before he was surprised, Yu Fei noticed that the sword he had just stabbed this thing had only broken a scratch on it, but it hadn't hit it hard.

The corner of Yu Fei's mouth twitched fiercely: "Oh my God...... Even the sharpening of the iron sword can't hurt it without the infusion of true qi?What the hell is this?"

According to Yu Fei's calculations, if the divine sword does not use true qi and stabs out a sword, even the cultivators in the early stage of the god transformation can't stop it, and this thing is actually just a piece of skin, which shows how thick its skin is.

Now Yu Fei can understand why this place is called a forbidden area, it turns out that not only can this place not use true qi and divine sense, but also has such a monster with a strong physique.

After this monster was stabbed by Yu Fei, he was even more furious, howled again, and pounced towards Yu Fei, and Yu Fei had to continue to meet it, fortunately, Fei's own body is not slow, otherwise a dignified mid-stage peak powerhouse will be shot to death by a stone monster......
