The imperceptible breath paused outside the castle for a moment and slowly entered the castle.

The ancient saint was shocked.

If it passes quickly, it means that it is taking advantage of the sentry to slacken, and there is no need to worry.

There was only one possibility to be able to enter calmly, and the sentry did not find him.

Being able to pass through safely under everyone's noses, among the people that the ancient saint was super familiar with, only Xiang Hongji, who had broken away from the Poison Sect, and Gan Rongrong, the immortal rat protector of the Dark Moon Hall, could do it.

However, these two men could not have been here anyway.

Could it be her?

Gu Shengchao thought of a person, but he didn't dare to confirm it.

Outside the city of Fanzhou, who killed the Fu King of the Wuwang Palace, the master of the Dark Moon Hall Yuan Hall was present at that time, and he saw Gu Shengchao's phoenix sword technique, and learned that his sword technique came from Phoenix Castle, so he left in a hurry.

Later, Gu Shengchao inquired that the name of the master of Yuan Hall was Yuan Luochen, and everyone knew that she was middle-aged, but no one had seen her true face.

It is rumored that it is those young men who have been favored by her and survived by luck, and it is also said that she is covered with black veils all year round and does not know her true appearance.

Thinking of this, Gu Shengchao couldn't help but break out in a cold sweat.

He locked onto the breath and crept closer to it, not daring to make a sound.

The breath stopped inside the castle, as if waiting for something.

At this time, there were more than 20 breaths in the castle one after another, and groups of three or five walked towards different city walls.

Now it's time for the sentry to take over.

Gu Shengchao suddenly understood that this person was waiting for an opportunity, waiting for the opportunity of the person who was on the way back to the house after the shift and was alone.

It was close to that aura, and it could be seen as long as he turned the alley, but Gu Shengchao stopped.

He can't guarantee that he will see the other party, but he knows that as long as he shows his head, the other party will definitely find out.

Sticking to the wall, Gu Shengchao silently crawled under the dilapidated eaves and hid his figure with the help of the night.

After the change of guard, everyone happily returned together.

One person broke away from the team and walked into the alley where Gu Shengchao was hiding.

"Hey, what are you going to do?" Someone stopped and asked.

"I can't hold back the peeing, you go back first, I'll be there soon." The man said as he lifted up his robe and relieved himself.

"Be careful, don't let that vampire get your eye on you." People laughed and walked away.

"Raven's beak." The man cursed.

After a small relief, he shook and tidied up his robe, turned around and just took two steps, when a strong wind rushed in front of him.

In his fright, he saw a black figure less than five steps away from him.

"!" He subconsciously shouted and turned to run, a hand already on his shoulder.

"Bang!"

There was a sound behind him, and the hand nudged him, leaving his shoulder.

With just a slight push, he fell forward.

When he got up and turned around tremblingly, the monster with sharp teeth and sharp mouth in his imagination was no longer behind him, and the two black shadows not far away were already fighting together.

Gu Shengchao saw someone sneak attack, jumped down from the eaves and waved a palm, catching the person who sneaked up by surprise.

The man hurriedly slapped Gu Shengchao into his hand, and immediately made a decision, and ran out of the alley to escape.

The moment it flashed from Gu Shengchao's side, Gu Shengchao smelled a faint aroma of fat powder.

How could the cooked duck fly away, Gu Shengchao then chased after it, and slashed at the back of the man's heart with a wave of his palm.

His life was at stake, and he had to be guarded, so the man turned around and parried, but was dragged by Gu Shengchao and couldn't escape.

The few people who had just walked away were also worried about their companions when they heard the movement, so they ran back with their respective knives and guns, just surrounding the two of them.

Gu Shengchao was unhurried, and used the Nine Heavens Biluo Palm to trap the other party, the greater the movement, the more people came, and the more stable he was.

But the person on the other side was flustered and exposed to everyone, and the more time passed, the unlucky person could only be himself.

As the moves of the two accelerated, the unique fat powder on each other's bodies

The smell spreads and becomes stronger at night.

Gu Shengchao slashed it with one palm, just waiting for the person to parry and then raise his foot and kick the opponent's knee, just when he was ready for everything, the person opposite disappeared inexplicably.

After a short hesitation, Gu Shengchao suddenly woke up, and the person opposite was in front of him, and he just used the stealth technique just now.

Even so, he didn't dare to act rashly, summoning his sword and slashing forward. It's late at night, and it's already a trance to see things, and you can't take it lightly.

However, the opportunity was fleeting, and that person was completely gone in full view, and no one knew where he went.

Gu Shengchao was annoyed, he sensed everything around him, and found nothing else.

Suddenly, two miles away from Phoenix Fort, a rapid gasp was briefly perceived.

The ancient saint flew over, and the breath was nowhere to be found.

On the way he and Lu Jin escorted Yunzhou Taishou back to the capital of the Dawu Dynasty, He Qiaocong, the Canglong Protector of the Dark Moon Hall, used the method of holding his breath to deceive his perception, and was almost successfully attacked by her.

Now it seems that this person also used the same method, using stealth to escape quickly.

Gu Shengchao's perception detection range is wide, but he can only search for the breath of living creatures, and cannot judge the specific shape, which is the only flaw.

By the time he sensed the other party's aura again, he was already five miles away.

And for a short moment, the other party held his breath again, and could no longer be searched.

The target that was close at hand, and finally retreated, and Gu Shengchao returned to Phoenix Fort in frustration.

Tian Mang had already rushed to hear the movement, countless torches were lit on the city wall, and he was listening to his subordinates report what had happened.

"Brother Gu has worked hard, have you found out the origin of the other party?" Tian Mang saw that Gu Shengchao was displeased, and asked softly.

Gu Shengchao sighed: "It should be a woman, good at stealth techniques, and her internal strength is good, I guess she is the hall master of the Dark Moon Hall, but there is no evidence."

"I've heard of the Dark Moon Hall of the Dawu Dynasty, is that possible?" Tian Mang also felt that this guess was a bit outrageous.

Gu Shengchao shook his head: "I'm not sure either, so I'm just suspicious, maybe, the Hidden Dragon Crouching Tiger of the Xilang Kingdom is a certain sect."

Tian Mang asked, "Whose class is it tonight?"

"Me." One person stepped forward.

Tian Mang ordered: "Now is an extraordinary period, starting tonight, we must send more people, no matter what we do, we must be accompanied by three people, and there must be no phenomenon of being alone, so as not to give the other party a chance to take advantage of."

"Yes." The man went down and arranged.

Looking at the dark night outside the castle, Tian Mang said: "I've also heard of some stealth techniques, but I've never seen them, according to what happened tonight, since we can't see her, do we have to think about some ways and can only outwit her?"

"It's the first time I've faced such a situation, so I'll go back and think about it later." Gu Shengchao didn't have a better way to deal with it for a while.

Tian Mang patted him on the shoulder affectionately: "It's the first time we've met, don't worry about getting tired, take your time."
