The shuttle hovered in the low sky for a while, and slowly landed at the gate of the city.

As it gets closer, Liubo City looks more majestic, and its prosperity and excitement are even more extraordinary.

It was clearly noon when the sun was shining brightly, but the gate of the city was still full of traffic and crowded.

"It is said that 1,500 chaotic epochs ago, there was an extremely powerful thunder beast Kui Niu entrenched on Liubo Shenshan, and its power shook the entire thunder field, almost supreme."

"Later, Emperor Shenxiao rose up, flattened Liubo Shenshan, and cut off Kui Niu's skull with a single stroke. Since then, he has exclusively enjoyed the thunderous luck between heaven and earth, and has been promoted to one of the seventy-two heavens."

"The skull of Kui Niu fell here, and over time, this city of Liubo was formed."

"Liubo City is so majestic and majestic, it's hard to imagine how elegant the Minglei Saber was in Emperor Shenxiao's hand back then, it could cut off Kui Niu's head with one stroke."

Yue Hongyu looked ahead and couldn't help admiring.

Of all weapons, she likes knives the most, followed by guns.

Don't look at the long spear on her back, part of the gun is used to confuse the enemy, and often the fatal blow of her thunderbolt is the knife hidden on her body.

"Ming Lei Knife? I threw it away in the White Night Evil Palace back then. This knife is just so-so."

The dark crow transformed by Gu Chen stood on Yue Hongyu's shoulder, he had no impression of Minglei Saber, but instead remembered the old servant who held the saber for him.

"Senior Gu is here again, bragging."

Yue Hongyu curled her lips. This senior indeed has great powers, but sometimes she can see through the nonsense she brags even with her experience.

Although Emperor Shenxiao died in battle in the White Night Evil Palace, his Thunder-Crying Saber is said to have been lost a long time ago. Before his fall, he should have held another Thunder-Crying Spear from the Emperor's Army. How could it be the Thunder-Crying Saber?

Senior Gu obviously wanted to say that he was the mysterious human emperor again, but unfortunately he didn't know enough about Emperor Shenxiao and Lei Yu, and ordinary monks could see through the lies he told.

"Ha ha."

Gu Chen didn't bother to explain, and looked at the giant city ahead.

Although thousands of chaotic epochs have passed, with his soul state, he can still feel a trace of the fierce aura belonging to that Kui Niu.

This fierce air permeated the ground in the city, as if its resentment was lingering.

Gu Chen felt it carefully, and suddenly narrowed his eyes slightly.

Is it his illusion?

He seemed to have sensed something else from that fierce air.

It seems to be, vitality? !

Gu Chen couldn't help closing his eyes, feeling more carefully, while Yue Hongyu walked into the city.

Flowing Wave City is divided into outer city, inner city and upper city.

The inner city and the upper city are mainly inhabited by local aristocratic families, while the outer city is populated by merchants, which shoulder the huge economic functions of the world.

It can be said that if Liubo City cannot find the last material that Gu Chen needs, then he will walk through the entire minefield, and there is a high probability that he will only return empty-handed.

Yue Hongyu has been by Gu Chen's side for two years, and she already has some experience on what to do when walking outside.

When she was in a small place, she would pretend to be a foreigner and try to avoid attracting attention from others.

But in a big city like Flowing Wave City, she didn't hide her identity.

Because since the death of Emperor Shenxiao, many places in Leiyu have been hostile to the human race.

In small places, people can't see that they are human races, which can avoid harassment.

But in a big city like Liubo City, if she continued to pretend as a human race, it would be easier to attract the attention of some big forces.

With her current cultivation, there are still many strong people who can see her disguise, so in order to avoid attracting attention, she should show her real face in such a big city.

The same is true for Gu Chen, when he was in a small place, he would often not follow Yue Hongyu, but would hide in the dark and only show up when necessary.

And in Liubo City, although a dark crow is inconspicuous, it sometimes attracts the attention of some experts. It is just beside Yue Hongyu, like her spirit beast, but others will think it is commonplace.

According to the usual habits, Yue Hongyu found a small inn in the outer city to stay in an inn near Fangshi.

During the whole process, Gu Chen didn't speak, and kept his eyes closed, Yue Hongyu felt a little strange.

Gu Chen didn't speak until he was about to go out to look for materials in the market.

"Go find it yourself, I have something to do."

Yue Hongyu asked curiously, "What's wrong?"

"nothing."

Gu Chen made a fool of himself, Yue Hongyu didn't ask any more questions, and went out obediently alone to inquire about the news.

After Yue Hongyu left, Gu Chen looked at the sky outside the window and frowned slightly.

"Nowadays, the coverage of spiritual consciousness is still too small. It is not easy to accurately capture the location of that ray of breath."

Gu Chen had some guesses, and if the guesses were true, the source of that breath might be able to be used by him.

However, although the soul state of his sub-soul is the same as that of the deity, his strength is too weak. Although it has increased in the past two years, it is not much, and the scope of his spiritual consciousness is very limited.

He sensed it carefully for a long time, and he could probably determine the location of the source of the breath in the upper city. As for the specific location, he might have to get closer to sense it.

Gu Chen thought about it for a while, and the body of the crow trembled for a while, as if it was a double image, and two other crows appeared.

The biggest difference between these two crows and the real one is that their eyes are red instead of golden.

Two black crows flew out of the window without a sound, merged into the shadow of the street corner, and cautiously moved towards the upper city.

In the process of advancing, their shapes gradually changed, one turned into a black cat, and the other turned into a divine eagle.

The black cat is on the ground, and the eagle is in the air. Through their perspective, Gu Chen radiates his spiritual power and carefully searches for the breath.

Passing through the outer city, the number of people in the inner city suddenly decreased, but there were still many.

When they approached the border between the inner city and the upper city, the flow of people suddenly decreased significantly, and the number of high-rise buildings in the city became smaller and larger.

Inside and outside those luxurious mansions, the restrictions on vigilance and protection began to increase, and the number of patrolling guards also increased. A cat and an eagle became eye-catching.

Gu Chen stopped carefully, knowing that he was not good enough to move forward.

"It should be almost here."

The black cat lay on a corner, and Gu Chen began to sense it with his heart.

When I was in the outer city, I could clearly feel the direction of the breath in the upper city, but when I arrived in the upper city, I felt that the breath seemed to be everywhere.

This is a good thing, it means that it is very close to the location of that ray of breath, if the distance is too close, it will make the lake sense.

The black cat lay at the base of the wall for half a day, Gu Chen searched and became confused.

"What's going on? No matter what, I can't capture the exact location. It seems to be not far away, but I can't find it."

Gu Chen suspected that his mental state had dropped, wouldn't this be a waste of time?

"What a poor kitten."

Suddenly, Gu Chen felt a burst of softness and picked him up, opened his eyes, and in front of him was snow-white like steamed buns.
