Using this characteristic, she can not only build a powerful intelligence network in the capital, but also quickly establish an intelligence network anywhere in the world where cockroaches exist.

As for the reason why Tianya was trained in the first place, it was naturally to find the wind chimes and some things left behind by its master.

Unfortunately, for various reasons, it wasn't found at the beginning.

Later, even the crow gave up.

Now, this little sweetheart has finally come in handy.

Upon hearing this, Feng Ling realized that although this little sweetheart was a bit disgusting, her skills were very reliable.

"Then let's not delay, I'll have to trouble you, young... senior."

"Oh, Patriarch Feng, there's no need to be so polite. Lord Tianya is my benefactor, so you are the patriarch of my benefactor. Just call me Little Sweetie."

Wind Chime's Inner Thoughts:

It's not that I don't want to shout, it's that I really can't...

Then, Little Sweetie asked Wind Chime to take her to the nearest place so that the search area could be covered more thoroughly.

So, taking advantage of the Wind Clan's unique ability to remain invisible in another world, Feng Ling slowly approached the southwestern border that was occupied by the demon race.

The Dark Spirit Butler controls the entire process, and will immediately stop if there is any risk of being discovered.

It turned out that the other party was clearly on guard against the Feng family's invisible Yin-Yang realm. Energy fluctuations from various otherworldly detectors filled the air, and the Dark Spirit Butler was very sensitive to them.

Even from a great distance, the Dark Spirit Butler had already stopped.

Is this place okay?

The wind chime asked, but Little Sweetie shook her head:

"That's not enough. I can only cover 10% of the outside of that city, which is far from sufficient."

Fengling glanced at the distance; it seemed they still needed to travel about 20 kilometers...

So Fengling had Tianya take the little sweetie and head straight ahead, just like a patrol. Tianya had been patrolling for the past few days, and the other side probably didn't expect that Tianya was carrying a cockroach.

To make it easier to carry, Little Sweetie's body shrank to the size of an ordinary cockroach before she crawled into the crow's pocket.

Be careful not to touch my cigarette.

Tianya gave his instructions.

"Rest assured, Lord Tianya."

Thus, under the watchful eyes of everyone, the Sky Crow left the Feng family's otherworld, soared over the group of spirit masters, and flew towards the distant southwestern border.

Yan Dingyun noticed it immediately. At first, he didn't pay much attention, but gradually he realized that the route the Sky Crow was taking was much deeper than before. He narrowed his eyes and wondered what the Wind Chime was up to.

As the Sky Crows ventured deeper into the region, the demons on the southwestern border became more vigilant.

"Why are those crows getting so close this time!"

"What should we do? Does he want to start a war? Should we take the initiative and attack?"

"Take the initiative? Are you out of your mind? Report to the magistrate immediately."

The arrival of just one crow caused some panic among the demons in the city.

After all, those were celestial crows, and probably only a few demon kings in the city could stop them; they would be reborn in an instant.

But the crow suddenly stopped; the distance was right, and Little Sweetie immediately unleashed her power.

But in order to conceal its demonic energy, the Sky Crow also unleashed its own domain and ventured into the night!

Endless darkness surged toward the border, but the domain stopped on a certain plane.

The other party actually has a way to stop the spread of the Sky Raven Domain.

Even Tianya couldn't help but be somewhat surprised, wondering to himself:

"Can you still use your skill?"

"No... my sorcery can't penetrate that barrier either."

Upon hearing this, Tianya didn't linger and immediately turned and left.

As darkness vanished, the demons in the city immediately cheered.

"Hahaha! Even the Sky Crow can't do anything about it!"

"Even the crows can't get in. As expected of the Demon King!"

This wave of enemies was in high spirits, but it was all for naught. No matter how high their spirits were, they dared not cross the newly built defensive line of China.

After returning home, Tianya apologized to Fengling, saying that he hadn't been able to help.

"It's alright. Since they dared to be there so openly, they must have been on guard. I guessed it."

"So what's our next step?"

Given the situation, it's impossible for Little Sweetie to transform into her; she would definitely be discovered immediately.

The only option now is to sneak into the southwestern border. Fengling thinks that as long as she can get Xiaotian into the occupied city, she will be able to quickly find the place where Chiye is being held.

But how to blend in without being detected is too difficult.

While pondering, the Dark Spirit Butler reminded the Wind Chime:

"Master, Yan Dingyun has arrived."

Upon hearing the mention of Yan Dingyun, Fengling suddenly had a flash of inspiration:

"Please come in quickly."

Before that, he quickly told Little Sweetie to hide.

After Yan Dingyun entered, he immediately asked:

"What did Sky Crow do just now? Test the waters?"

Wind Chime nodded:

“I originally wanted to send Sky Raven to probe and see if we could get any useful information, but the other side has a strange barrier that even Sky Raven’s domain cannot break through.”

"Do you need my help? I can break that barrier."

"That would alert them. However, I do need your help with something."

"What?"

The wind chimes whispered a few words in Yan Dingyun's ear, and Yan Dingyun immediately refused:

"Absolutely not! It's too dangerous!"

"Don't worry, I'll be fine."

"I'm not saying you're in danger! It's those freshmen who are in danger."

Fengling hoped that Yan Dingyun could set a new task for the new students, to conduct the assessment as close as possible to the city, and to lure the demons in the city to make a move.

Meanwhile, Fengling and the others mingled among the students, using his unchanging skills to pretend to be the students who had been arrested.

Of course, doing so carries great risks. The Wind Chime's incarnation time is only half an hour. Once inside, it must find Akeno within a very short time. Otherwise, if it is discovered, it will alert Akeno, and Akeno will be taken into custody immediately.

At that point, the wind chimes will be at a disadvantage.

However, Yan Dingyun disagreed with this.

Since the other side has already captured enough hostages, isn't doing this just sending hostages away?

Feng Ling carefully explained her plan to Yan Dingyun. With the presence of the Feng family's otherworld and the Dark Spirit Steward, she could ensure that the new spiritual masters would not be captured, and that only the Feng family and a few other demon clans would be captured in the end.

But Ding Yun did not believe this statement:

"I see, you're trying to use this opportunity to snatch someone else, right?"

Wind chimes: ...

"I'm doing this to save lives! What other way do you have?"

"How much longer do you want those hostages to be held captive? Do you really think those demons won't kill them?"

"They must first stimulate their fear and despair to their strongest point before killing them and cultivating them into powerful demons. That despair and fear will only make those demons stronger and stronger. The longer it drags on, the more it is the result they want to see."

"They can restrain us while simultaneously improving their own strength."
