"You can sense us using voice transmission?" Lu Xin was somewhat surprised.
Li Mulin replied via voice transmission: "Outside, I might not notice, but here, divine sense is suppressed, and I can feel the fluctuations."
"Impressive."
Lu Xin knew this was the other party's method; he couldn't sense it himself.
However, he certainly couldn't reveal the content of their conversation. If she knew that Tian Zijin was teaching him to freeload off her, he wouldn't mind, but Tian Zijin would probably give him a cold shoulder.
It could even lead to a falling out.
He wasn't someone who would betray a teammate.
So, he casually brushed it off: "It's nothing, just discussing some private matters."
"Is it related to me?" Unexpectedly, Li Mulin persisted, sending another voice transmission.
Lu Xin was surprised again, not expecting her to be so perceptive, able to guess some of it. He prevaricated: "Daoist Li, you should know that the more curious one is, the closer they often get to danger."
"Oh? Are you saying that if I knew the content of your conversation, you would kill me to silence me?" Li Mulin said.
Lu Xin was stunned, somewhat speechless, "It wouldn't come to that. I'm just telling you a principle, like telling you not to make yourself so fragrant."
Li Mulin didn't reply for a long time. Just when Lu Xin thought she had given up on probing, she suddenly said: "Then I'll also tell Daoist Huanglong a principle: you'll never have a chance."
Lu Xin was momentarily stunned upon hearing this, "So, she knows the specific content of our voice transmission?"
Judging by this, she definitely knew. What he couldn't understand was, since she already knew, why was she deliberately asking him what it was all about?
"Could it be that she's curious as to why I don't have the intention to freeload off her?"
Lu Xin suddenly recalled his perfunctory "instigation" to Tian Zijin.
Forget it, he was too lazy to think about it if he couldn't understand. Anyway, Huanglong had no chance; what did it have to do with him, Lu Xin?
Besides, he didn't have any thoughts in that direction.
This matter came to an end. The four continued forward, soon reaching the middle section of the valley. At this time, another wave of ghost fire torrents erupted, and the three once again tried their best to resist.
Having experienced the previous event, Lu Xin focused intently on the top of his head, waiting for the torrent to pass.
However, at this moment, a sudden change occurred. It turned out that this time, the surging torrent was mixed with snake-like creatures, densely packed, as if ten thousand snakes were emerging from their lair, mouths agape, heading towards them.
"Not good, these ghost fires have nurtured fire spirits. There are too many; we probably can't withstand them. Retreat quickly!"
Tian Zijin's expression changed drastically, and she controlled the Fire Avoidance Pearl to retreat quickly.
The other three didn't dare to be negligent either.
However, they still underestimated the speed of these fire spirits. They had only flown a short distance before they were about to be caught up by the fire spirits.
"Defend with all your strength!"
Tian Zijin shouted loudly, fully activating the Fire Avoidance Pearl while also summoning the Heavenly Heart Plate.
The three also summoned their respective spiritual treasures.
"Boom!"
Just as their protective barriers rose, the fire spirits arrived, crashing into their barriers.
The immense impact caused the faces of the four under the barrier to turn pale, though Lu Xin was faking it.
This bit of impact didn't cause any harm to his physical body.
However, his mana was still a bit weak, and the Five Elements Formation was compressed to within a few feet around his body.
And it was somewhat precarious.
The other three were in similar situations.
"This is troublesome!" Tian Zijin's expression was unsightly.
These fire spirits weren't like those ghost fires, which simply flowed away. Instead, they were like a group of eels finding raw meat in the water, surrounding their barriers and constantly colliding and gnawing at them.
If this continued, they definitely wouldn't be able to hold on for long.
"Do you have any ideas?"
He looked at the three.
Nalan Zhizhu and Li Mulin shook their heads, indicating that they couldn't think of any solutions for the time being.
"Daoist Huanglong, what about you?" He then turned his gaze to Lu Xin.
Lu Xin didn't answer but instead carefully looked at those fire spirits, thought for a moment, and said: "These fire spirits aren't individually strong, just numerous. Perhaps we can use offense as defense and fight our way out."
The three's eyes lit up upon hearing this. Then, Nalan Zhizhu raised a question: "But these fire spirits are harder to resist than ordinary ghost fires. How can we free up our hands to kill them?"
After she finished speaking, everyone looked at Lu Xin, because among the four, only he didn't need to control fire avoidance items.
They just didn't know if Lu Xin had this ability.
Lu Xin was wondering whether to take out the Divine Fire Cauldron to collect these fire spirits, after all, although these ghost fire spirits were powerful, his Divine Fire Cauldron was their natural enemy.
After thinking about it, he took out five formation flags and said: "I have a Five Elements Sword Formation, which is a proactive killing formation. It should be able to help us fight our way out."
This formation was inspired by the Five Elements Formation and had never been used. Today was a good day to test its power.
"Didn't Daoist Huanglong say that he lacked offensive means?"
Nalan Zhizhu recalled what Lu Xin had said when dealing with Xiang Liu earlier.
Lu Xin smiled and explained: "The reason why I, Huang, have been able to get to where I am today is because I know a little bit of everything. This set of sword formations was something I figured out myself, and I've always been afraid to show it off."
The three were even more surprised upon hearing this, not expecting that the other party not only understood formations but could also create them himself.
They just didn't know how powerful it was.
"Alright, I'm going to withdraw the Five Elements Formation. You guys help me block for a bit." Lu Xin didn't plan to reveal his ability to control two formations at the same time, after all, the more trump cards he kept hidden, the better.
"Daoist Huanglong, feel free to act."
Tian Zijin said. Although he didn't know if the other party's sword formation would work, he could only let him try now. If it really didn't work, he would have to give him the Fire Avoidance Pearl and use his own methods.
Then, Tian Zijin and Nalan Zhizhu expanded the range covered by the Heavenly Heart Plate and Yellow Bell as much as possible towards Lu Xin's side.
Upon seeing this, Lu Xin withdrew the Five Elements Flags, then waved his hand and flung them out. The five small sword formation flags flew out, and similar to the Five Elements Formation, the five flags were arranged in five directions, each in charge of one position.
"Activate!"
Seeing the five flags in position, Lu Xin solemnly shouted, and with a point, five beams of mana light shot out, injecting into the formation flags. The five flags immediately fluttered in the wind, shooting out countless mysterious sword lights, covering the sky and sun.
In an instant, the sound of metal entering flesh rang out around them, endlessly.
"It works!"
The three people next to them showed joy as they watched the ghost fire spirits being constantly crushed by the sword light.
"Daoist Huanglong, well done!"
Tian Zijin praised. He had been somewhat skeptical of whether the formation created by the other party would be powerful, but now it seemed that he had been overthinking it.
Nalan Zhizhu and Li Mulin also didn't expect that the other party was really a formation master. Although this Five Elements Sword Formation seemed simple, its ability to easily crush these ghost fire spirits had already reached the standard of a seventh-order killing formation.
Lu Xin also felt a sense of accomplishment. In the past, he had always practiced other people's things, but now he could also create some of his own things, and they were very powerful.
"Alright, while the formation is effective, let's fight our way out." Calming down, he spoke.
"That's exactly what I intend."
Then, the four cooperated, with three controlling the fire avoidance treasures and supporting the protective shields, while Lu Xin focused on controlling the Five Elements Sword Formation to clear the way forward.
Soon, they fought their way to the end of the valley, braving the torrent formed by the ghost fire spirits.
"We're finally about to get out." Nalan Zhizhu looked at the exit ahead and breathed a sigh of relief.
Lu Xin's expression changed upon hearing this. The most taboo thing to do is to celebrate prematurely, because this often foreshadows an accident. He quickly shouted: "Daoist Nalan, be careful with your words. Let's speed up and rush out in one breath."
"What's wrong?"
Nalan Zhizhu asked in confusion, the other two also looking puzzled.
Lu Xin was too lazy to explain and took the lead in speeding up. However, it was still too late. The stone wall at the end of the valley suddenly cracked open a huge gap after a burst of shaking.
