As soon as Xu Feng finished speaking, Xian Lieyang suddenly staggered forward, as if he was hit by something invisible from behind.

He turned his head suddenly and swung his sword, but found that he had hit nothing. When he was alertly putting away his sword to defend himself, a hand like a phantom had already hit his back.

However, Xian Lieyang was not surprised by this move. Instead, he grinned and resisted it as if he had expected it. While spitting out blood, he let out a low roar and actually threw the golden knife in his hand forward.

The moment the golden knife left his hand, it let out a whistling sound and flew towards the space where the phantom was, transforming into a sky full of knife shadows that enveloped and strangled that entire space!

However, Xu Feng and the others all shook their heads. Yan Yi said, "This is the way of ghosts, right?"

"Not bad." Xu Feng nodded.

In a place where Xian Lieyang could not see, Wang Li had actually been hiding in the void since just now and had never made a move. The one attacking Xian Lieyang was the ghost general that Wang Li had summoned before. That ghost was invisible, so Xian Lieyang had always mistaken it for the invisible Wang Li.

At the moment when the golden blade light was about to strangle the ghost general, Wang Li suddenly rushed out from the void, his whole body surrounded by flames, like a fire lion, roaring and crashing into the slightly distracted Xian Lieyang. Countless iron feathers from the wings behind him turned into sharp blades and madly penetrated into Xian Lieyang's body.

Xian Lieyang turned into a bloody man. Just as he was about to fight back, Wang Li punched him hard. While using the force to retreat, he said coldly in the air: "Explode!"

boom!

Under the gaze of everyone, Xian Lieyang exploded in mid-air like a ignited barrel of explosives!

I won.

"Huff--huff--" After Wang Li fell to the ground with a pale face, he lay on the ground in a husky manner, breathing in the fresh air with deep gulps, his mind full of thoughts about the battle just now.

Realizing that Xu Feng and the others were walking towards him, Wang Li struggled to stand up and looked at everyone: "Let's go."

Xu Feng shook his head slightly, and saw Ba Tuoying behind him appear at the place where Xian Lieyang died. A big hand emitting a faint golden light actually grabbed a translucent purple little man from the void.

"Boy, you're still a little short of the mark," Ba Tuoying glanced at Wang Li, who had a grim expression on his face, "The spirit of this evil immortal is somewhat different from ours."

As he said this, he glanced at Xu Feng.

Seeing him nod, Batuo Ying grinned grimly, stuffed the purple man into his mouth while roaring, chewed it a few times, and swallowed it.

"Delicious." Batuo Ying said somewhat intoxicatedly.

Wang Li's eyes widened. It was the first time he saw someone stuff this thing into their mouth like eating something. Is this edible?

Seeing his surprised look, Xu Feng said, "The Qingtian Sect is full of these rough guys. If you see them often, you will know that there are also those who eat Yuanshi."

Wang Li laughed when he heard this, but when he thought that this was what Xu Feng said, his face suddenly darkened: "You don't need to talk nonsense."

Everyone was speechless, but Xu Feng didn't care: "Okay, let's go see how Xiaoshui and the others are doing in breaking the formation."

After cleaning up the battlefield, everyone headed straight into the clouds and mist deep in the swamp.

The plan is as follows: Xu Feng and Nan Tianxing are in one group, and are responsible for dealing with the possible Daoxue Realm immortals; Qingshanjun and Ba Tuoying are in one group; and Yan Yi and Wang Li are in one group, and are responsible for the remaining two strongholds.

Wang Zhishui, Qingdan and Zi Buyu were responsible for breaking the formation that covered this secret realm.

Wang Zhishui and Qingdan brought with them the items that the sect's great men had deduced and made to break the formation, as well as some special magic weapons, such as the ancient forbidden shuttle and other treasures used to break the formation.

Zi Buyu was quite familiar with the art of formation. As long as the formation could be broken, this place would no longer be secret, and Xu Feng and others would be able to enter the formation.

As for how to find the seniors from the three sects after entering the formation, the sons of gods naturally have their own ways.

However, it is hard to say whether this formation can be broken.

Since the immortals were willing to pay such a high price to do this, they must have considered various factors, including the possibility that someone might break the formation, etc. So what kind of trouble would they prepare? It is still unknown.

When everyone met up with Qing Dan and the others, they saw Wang Zhishui standing in front of an invisible barrier with an anxious look on his face. There, there was a palm-sized hole that was shrinking rapidly. When Xu Feng and the others arrived, the hole had disappeared.

"What problem have you encountered?" Wang Li frowned first.

Wang Zhishui ignored him and looked directly at Xu Feng: "The Forbidden Shuttle can only make a hole as big as a human head, but we found that this formation has not only one layer, but three layers, blocking all energy, sound, divine thoughts, and vibrations. It is almost like opening up another space."

"But it's not another space, it's just pure isolation."

Just then, Zi Buyu came from the other side holding a black forbidden shuttle and spoke to everyone.

His attainments in formations were almost on par with Xu Feng's. Back then at the Human King's Tomb, the two already knew each other's abilities.

"I made the same discovery here." Qingdan came from the other side holding another forbidden shuttle.

"You're going to let such a person of unknown origin use our forbidden shuttle?" However, Wang Li frowned and questioned Qingdan.

Without waiting for Qingdan to reply, a slap came directly on Wang Li's shoulder. Wang Li was horrified to find that the energy in his body had disappeared in an instant and he was unable to move. When he turned his eyes, he realized that it was Xu Feng who had attacked him.

"Stop making so much noise. Be quiet for a while." Xu Feng glared at him, then looked at everyone and said, "Master Zi Buyu is a master of formations and has a wide range of knowledge. What he says can be trusted."

Everyone nodded and looked at Wang Li with amusement.

Zi Buyu snorted and laughed: "I have broken more formations than you have eaten salt. We have used many methods to break this formation, but we can't break it. The structure is complicated, and what is running is immortal energy instead of ordinary energy. This makes many of our methods directly ineffective."

"We used the Burning Spirit Array developed by the seniors from the three sects to make the immortal essence circulating in the array burn on its own, and then used the Breaking Ban Shuttle to break it together, but we could still only open a hole the size of a human head, and this is only the first layer of the array."

"After all, if the Yuanli leaves our body, there will be no blood heart to protect it."

Xu Feng nodded: "Let me try."

He took the Forbidden Breaking Shuttle from Qing Dan and said to Zi Buyu, "Master, please give me the process of breaking the formation and the detailed experience."

Upon hearing this, Zi Buyu took out a jade slip from his arms, imprinted it on his forehead, and handed it to Xu Feng after a while.

After reading the jade slip, Xu Feng pondered for a moment, then called Yan Yi and Nan Tianxing, along with Zi Buyu. The four of them squatted on the ground and started discussing and calculating.

Seeing this, others could only step back and not disturb them.

Although the Northern Fire Sect is not good at formations, Yan Yi is a great formation master. His research on fire has enabled him to dabble in formations as well, and he has made considerable achievements.
