Xuanyuan Hong didn't know, but judging from the vision of heaven and earth that was triggered, once Princess Yuefei's cultivation was successful, the power was shocking, but this extraordinary exercise, most of the cultivation conditions were very harsh, and those who were qualified to cultivate might not be able to practice, and even if they did, they would have to pay a high price.

After a full quarter of an hour, the vision of heaven and earth on the mountain peak disappeared, and this quarter of an hour was enough time for Xuanyuan Hong to determine the location of the retreat, and he immediately unfolded his body and rushed towards the place where the vision of heaven and earth appeared, although it seemed to be very close, but the actual distance was very far.

Syllable!

When Xuanyuan Hong was advancing, a ball of blood exploded in the distance in front of him, it was a small red snake that had been one foot long, and its head was cut off by a sharp sword, the red little snake he knew, it was a mutated poisonous snake, even if a strong person in the longevity realm was bitten, it would be paralyzed for a long time.

Of course, it won't be a demonic beast with a sword, Xuanyuan Hong immediately restrained his breath, fortunately, the little snake appeared in time, otherwise he would have been discovered.

Xuanyuan Hong moved forward cautiously, with the assistance of the martial arts light brain, the vitality did not leak at all, if he could not be seen directly, on the scanner or in the divine induction, he was a lifeless object, but the position would move.

Of course, this method can conceal some people, but it can't hide people whose cultivation is much higher than him, and of course, it doesn't matter if the gap in cultivation is not too big.

"As I expected, Princess Yuefei's sentry has stretched so far. Soon, Xuanyuan Hong found that the person who killed the snake with his sword just now was wearing a camouflage coat, hiding on the branch of a big tree, constricting his breath, and motionless as if he had grown on a tree.

The little red snake just now, if it hadn't climbed on him, he wouldn't have killed it with his sword at all, and he wouldn't have been discovered by Xuanyuan Hong.

Found a secret sentry, Xuanyuan Hong began to be very vigilant, you will not have only one secret post, there must be other people nearby, if you rashly pass through here, or take the secret sentry abruptly, there is a ninety percent chance that his whereabouts will be exposed, and he cannot be killed.

Xuanyuan Hong thought quietly for a while, and decided to sneak over quietly, ignoring the dark whistle in the tree.

The dark whistle on the big tree would never have thought that when he was quietly lurking, he had already walked on the edge of life and death.

The cultivation of the dark whistle is not high, only the Soaring Realm Ninefold, and on the way when Xuanyuan Hong came, he had already rushed to the Longevity Realm Sevenfold with nine drops of divine spring, and the huge cultivation gap made Xuanyuan Hong very easy to deal with these dark whistles, and passed through the peripheral area.

"It seems to be close to the core area!" When Xuanyuan Hong advanced, he found that there were actually some secret sentinels in the main positions, and the cultivation had been promoted to the Longevity Enhancement Realm, even if it was only a powerhouse in the early stage of the Longevity Enhancement Realm, it was a very extravagant and wasteful behavior to use them as secret sentinels.

Only a person like Princess Yuefei, who was born in a wealthy royal family, could do so and have the ability to do so.

However, Xuanyuan Hong's current cultivation has risen sharply, and although there are people in the early stage of the Longevity Enhancement Realm as a secret whistle, he still didn't have much effort to pass.

In the map, there is no detailed information about Princess Yuefei's retreat, probably for the sake of safety, only the most trusted people of Princess Yuefei know the details of the retreat, and these details will not form any records until the end of the retreat.

Xuanyuan Hong could only slowly grope forward, but he believed that even if he couldn't find a place to retreat, Princess Yuefei's retreat would be difficult to gain, and Princess Yuefei's retreat was an important resource that Xuanyuan Ling'er contained in the blood of the power of the ancient black jade phoenix, and it was impossible to provide it anymore.

Even more seriously, the lack of necessary cultivation resources will even lead to going mad, and the cultivation will not only not improve but will decline.

However, compared to this kind of probabilistic event, Xuanyuan Hong prefers to do it himself, in case of various accidents.

Xuanyuan Hong believed that he was close to the place of retreat, because the secret sentinel of Minggang in front of him had all been replaced by powerhouses of the Longevity Realm.

Even if he had the sevenfold cultivation of the Longevity Enhancement Realm, the many Longevity Enhancement Realm powerhouses in the face had to be careful to avoid the crisis of being discovered.

"What's going on?" Xuanyuan Hong had just flashed to a tree, and he noticed that the scene in front of him had changed, and he immediately realized that he had been hit by the trap.

Xuanyuan Hong did not panic, a large part of the casualties after being hit by the enemy's organs were caused by panic, as a strong man with rich combat experience, he would not make such a mistake, immediately raised his vigilance and stood in place, quickly reviewing the surrounding situation.

It's a teleportation trap that has been teleported from the same place to another place, but generally the teleportation distance is not too far, otherwise the cost of setting up the trap will skyrocket, and in most cases, the teleportation trap will teleport people to a dangerous environment.

The place where Xuanyuan Hong appeared was a cave environment, and in the dim light, there were caves that did not know where to go.

The environment is very similar to the mine, but ...... How do you get out?

Xuanyuan Hong explored and advanced little by little, it was difficult to guarantee that there was no killing mechanism here, he had to be cautious at every step.

Xuanyuan Hong had just advanced less than twenty steps when he felt a very slight vibration, and immediately realized that something was wrong, and as soon as he left the place and shot out, the stone above his head burst open, bursting out of a dark red faint smoke.

With the help of the force of the explosion, the dark red smoke instantly enveloped a ten-meter-long section of the cave, dyeing the cave a pale red.

Suddenly, Xuanyuan Hong was very shocked by the scene, under the pale red smoke, the rock cave wall was rapidly sandy, and the hard rock turned into fine sand, which flowed down from the stone wall and the top of the cave, obviously these sand were fresh goods that had just formed.

How is sand formed, and is it natural in an instant?

Of course not, Xuanyuan Hong noticed that the area formed by the sand was the same area that was enveloped by the pale red smoke.

In other words, the reddish smoke turns the hard rock into fine sand, what a terrifying ability?

If Xuanyuan Hong's reaction was a little slower just now, he would also be shrouded in reddish smoke and turned into a pile of broken sand.

Xuanyuan Hong immediately made a detour, although the dark red smoke quickly dissipated, and the fine sand no longer continued to form, but he still made a detour, who could guarantee that the red smoke would not have a little residue, in case it was inhaled into his lungs, or stained his eyes, the consequences would be unimaginable.

Bypassing the extremely dangerous area of red smoke, Xuanyuan Hong just continued to advance, and the environment in the cave was very monotonous.

"According to the analysis, we are on the rise, and it is possible that this is a way out. "When Xuanyuan Hong was advancing, Wu Xueguang was not idle, constantly conducting various analyses of the cave, trying to find a way out, and at the same time, he was also monitoring the cave and trying to find traps in advance.

Suddenly, Wu Xueguang Brain issued a warning, and a metal reaction was found thirty meters ahead, and the stone wall contained pure metal objects.

"Pure metal?" There are not many pure metals in nature, except for gold, most of the other metals exist in the form of compounds, and metal reactions have been found behind the rocks, and they are arranged in a regular manner, obviously, this is also a mechanism.

Xuanyuan Hong immediately stepped back, and at the same time picked up a stone, the weight of which was not far from his weight, and rolled forward.

The rock rolled all the way over, and Xuanyuan Hong's spirit was highly concentrated, although he guessed that it was a mechanism, but after all, it had not been triggered and had not been seen.

As the rock rolled to the point where the metal reacted, a sudden sound of breaking through the air was heard, and a cold light flashed away.

Looking at the rocks he rolled past, there was no change at all, no, there was a change, there was a little white green smoke, and then a little spot began to appear on the hard rock surface, and these spots quickly expanded, becoming a regular arrangement of small holes, each of which was the thickness of a mung bean.

At this time, the rock is already full of holes, if replaced by a person...... The body is full of holes, and even if you don't die, you have to peel off your skin.

The hidden weapon, Xuanyuan Hong speculated that the cold light just now was a needle-type hidden weapon, and he didn't see it clearly because the speed was too fast.

With such a rapid firing speed, even if he hadn't prepared in advance, he would have been shot by these needle-type hidden weapons, and the consequences would be unpredictable.

"Replay the scene just now!" Xuanyuan Hong ordered Wu Xueguang Brain, the whole process just now has been recorded by Wu Xueguang Brain.

Replayed, under the display of slow motion, a row of steel needles shot out from the left stone wall and the stone wall under the foot, blocking the ten-meter-long cave in front and back, because the speed was too fast, resulting in an inch-long super-strong alloy metal needle, which had an extremely powerful penetrating ability.

The rock that Xuanyuan Hong rolled past was pierced by these metal needles, and the poison that broke through the metal needles corroded the rocks.

If it weren't for the corrosive poison, the rock would not have appeared in such a short period of time, and the metal needle was only the thickness of a human hair, and even if it penetrated the rock, the pinhole left behind was only a little bit, and it would not have been found at all if you didn't look closely.

It's dangerous!

Based on the two traps he had encountered, Xuanyuan Hong had every reason to conclude that this was for masters who could infiltrate.

The ferocity of the organ, any one who hits him Xuanyuan Hong is very dangerous, and at least a layer of skin must be pulled out before he can leave.

"You must leave this place as soon as possible, the two mechanisms you encounter are so powerful, who knows what else is more weird and powerful?" Xuanyuan Hong immediately made up his mind, but some things are obviously not in a hurry, especially in such an underground, it is impossible to find a way out.

Boom Boom!

There was a low roar from the depths of the cavern, which didn't sound very far away, but it could also be a trap.

What to do?

Xuanyuan Hong was a little hesitant, go out, he didn't have a clue at all, he was stepping up to find a way, if he walked around in the cave, it was likely to trigger more powerful mechanisms, but if he didn't move, he would also be trapped here, so it can be said that there are pros and cons to whether he can go or not.

Roar!

The sound came from the depths of the cave again, and it sounded clearer, like a kind of demonic beast roaring, but the sound source was a little far away, and the change of the sound in the cave had caused it to be seriously distorted in Xuanyuan Hong's ears, and it was not enough to identify the species.

To go or not to go?

Xuanyuan Hong had to make a decision, and the sooner the decision was made, the better it would be for him, and of course, it was possible to die early.
