In addition to changing one's own appearance and aura, the Transformation Breath Technique can also spy on the true appearance and spiritual pressure of other monks.

Song Shubai had already cultivated this technique to the Dacheng realm, and he could already exert many abilities of this technique, plus his own divine sense far surpassed that of monks of the same level, so he would be able to perceive the existence of those two foundation building monks so quickly.

If those two foundation building monks were just hiding their cultivation and mingling in Barter Street, it wouldn't make Song Shubai have a bad premonition.

The main reason why he had a bad premonition was because the aura exuded by these two foundation building monks was extremely similar, which proved that the two foundation building monks must have known each other.

Moreover, they have been spying on the formation power of Huoyunfang City, obviously wanting to do something in Huoyunfang City.

Zhou Xiong's wife, Zhao Jiao, in addition to having a mid-stage foundation cultivation, is also a second-order low-grade spirit array master.

She spent a lot of money to purchase a second-order high-grade Nine Phoenix Fire Spirit Array from elsewhere, and with her cultivation in the middle stage of foundation building and the attainments of a second-order lower-grade spirit array master, she was almost able to exert the full power of this second-order high-grade spirit array.

Therefore, in this Huoyunfang City, even if there are monks in the late stage of foundation building who make a move against Zhao Yao, Zhao Yao can resist the attack of the monks in the late stage of foundation building with the help of the second-order high-grade Nine Phoenix Fire Spirit Array.

Now that there are two foundation-building realm monks mixed in this Huoyunfang City, they are spying on the Nine Phoenix Fire Spirit Array in Huoyunfang City, and it is very likely that they are going to make a move against Huoyunfang City.

And the monk who made the move has a high probability that his cultivation has reached the late stage of foundation building.

After suppressing the chaotic speculation in his mind, Song Shubai wiped out the aura left by himself in the room, and prepared to leave Huoyunfang City now.

Song Shubai got off Huoyun Mountain, walked less than two miles, and then turned around and galloped towards Huoyun Mountain.

"It's a demon cultivator! What I spied on in Huoyunfang City before was the demon cultivator of the foundation building realm! Song Shubai's face turned pale, his feet were extremely fast, and he soon came to the foot of Huoyun Mountain.

Demon cultivators are monks who are completely different from monks like Song Shubai, and they also adopt the aura of heaven and earth to cultivate like Song Shubai, but in order to speed up their cultivation and promotion, they often use some extremely brutal means to kill a large number of monks and ordinary people, so as to cultivate magic techniques and exercises.

Such a monk is called a demon cultivator, and in the world of cultivating immortals, everyone shouts and fights at it.

Song Shubai had also heard of the notoriety of demon cultivation before, and he had also thought that he might encounter demon cultivation one day in the future, but he didn't expect to meet demon cultivation now.

Song Shubai's mind was full of thoughts, if he expected it to be true, the surroundings of Huoyun Mountain would probably have been surrounded by this unknown demon cultivator, and the monks who had left Huoyun Mountain before would probably have already been poisoned by those demon cultivators.

If he continued to choose to leave Huoyun Mountain, there was a great chance that he would be besieged and killed by the demon cultivators around Huoyun Mountain.

"But it's not safe to go back to Huoyun Mountain, Huoyunfang City has already mixed into the demon cultivation of the foundation building realm, and they will definitely do something to Huoyunfang City next."

Song Shubai's brows furrowed tightly, his brain was racing rapidly, and he wanted to find a way to save himself.

After a long time, Song Shubai re-entered Huoyunfang City, and he did not tell Zhou Xiong and his wife the news of the demon cultivation.

First, he didn't have a channel to see Zhou Xiong and his wife, and they might not believe him, and the most important thing was that if he told Zhou Xiong and his wife the news now, it might cause the hostility of those demon cultivators.

At that point, the chances of his death will be greater.

Rather than this, it is better for him to do nothing now, and when the demon cultivator and Zhou Xiong and his wife fight, he still has a certain chance to escape from the chaos.

Time flew by, and two days passed quickly.

Song Shubai's mood had been extremely anxious for the past two days, and after two days of his apprehension, he suddenly heard a monstrous noise coming from Huoyunfang City.

"It's the demon cultivator who has infiltrated Huoyunfang City who is destroying the Nine Phoenix Fire Spirit Array!" Song Shubai spoke out in horror.

Ever since he got the formation book in the Zhuji Cave Mansion, he had been consulting and comprehending that formation book, and now his attainments in the formation have risen rapidly.

Although he may not have reached the level of a second-order lower spirit array master now, it should be about the same.

"You are so bold that you dare to sneak into the Fang City!"

As soon as Song Shubai came out of the room, he saw a woman dressed in a fiery red shirt with an extremely plump figure standing in the sky above Huoyunfang City with a fiery red magic sword.

This woman is Zhou Xiong's wife, Zhao Jiao, she is a cultivator in the middle stage of foundation building, and she is also a second-order low-grade spirit array master.

The moment Zhao Yao's imperial sword flew out, his eyes were locked on the bodies of the two foundation building demon cultivators.

The moment these two foundation building demon cultivators destroyed the formation, they had already revealed their identities.

They are all cultivators in the middle stage of foundation building, and Zhao Yao's strength in this Nine Phoenix Fire Spirit Array is extremely strong, and these two demon cultivators in the middle stage of foundation building cannot be Zhao Yao's opponent at all.

"Zhao Yao, your opponent is not our brother!" The two demon cultivators smiled coldly, and then a bloody aura erupted from their bodies.

The Qi Refining Realm cultivators around them were attacked by this bloody aura, and a terrible scream suddenly came out of their mouths, but in a moment, their flesh and blood were refined by that bloody aura.

At this time, the aura around the two Demon Cultivators of the Foundation Building Realm rose rapidly, and they directly reached the standard of the middle stage of Foundation Building.

After Zhao Jiao saw this scene, a surging fire appeared in her eyes, and when the spiritual light flashed in her hand, a fiery red phoenix seal emerged.

A crisp cry came from the phoenix seal, and then it roared and poured down on the bodies of the two demon cultivators.

At this moment, a stronger spiritual pressure appeared outside the Nine Phoenix Fire Spirit Array, and the owner who exuded this spiritual pressure was a woman in a purple-black dress.

This woman's figure is plumper than Zhao Yao, and the purple-black dress on her body is half-exposed, and when she walks, large areas of snow-white skin are revealed from time to time.

This woman stepped on a dark purple lotus platform under her feet, and she stood outside the Nine Phoenix Fire Spirit Array suspended in the air, standing opposite Zhao Yao in the Nine Phoenix Fire Spirit Array.

"Demon cultivation in the late stage of foundation building!" After Zhao Yao saw the woman in the purple and black dress, a dignified look suddenly appeared on her face.

This woman is a late-stage foundation building cultivator, and now there are still two early-stage foundation building demon cultivators in this Huoyunfang City, and now she is not sure if there are other foundation building realm demon cultivators hidden in this secret.

"Zhou Xiong shouldn't hurry up and get out to meet the enemy!" Zhao Jiao's heart was extremely anxious, and she let out an angry shout from her mouth, asking Zhou Xiong to appear quickly to meet the enemy.

It's just that after a while, Zhou Xiong's figure still didn't appear.
