Dongfang Xiuzhe waited for more than an hour, and just when he was about to run out of patience, a light crisp sound suddenly came out of the keyhole.

"Kaka!"

This sound is particularly prominent in this silent passage, and it is difficult to hear it.

"It's finished!" said Flo with a low cheer, as if he was afraid of waking someone up.

Dongfang Xiuzhe hurriedly came over and said, "It's finally opened, the speed at which you open the door is too slow......

The sound stopped abruptly as he saw Flo repeat the lock-picking steps again.

His brows furrowed slightly, and Dongfang Xiuzhe hurriedly asked, "Isn't the door already open, what are you doing?"

Flo didn't look back and said: "Only the first secret lock has just been opened, and there are eight hidden locks left, which will be opened soon." ”

Dongfang Xiuzhe slapped his forehead and spoke in his heart: My God, do you have to wait a few more hours by yourself?

He could no longer believe Flo's "soon", and he didn't want to spend hours waiting for it.

Patting Flo's shoulder, Dongfang Xiuzhe said with a serious face: "You dodge it, I'll figure out a way for this door, if you follow your method, it's too slow." ”

"Are you coming?" Flo was obviously stunned, and turned his head to stare at Dongfang Xiuzhe suspiciously, "This is not an ordinary door, and it is not a simple matter to open it. ”

Back then, Flo wanted to open the door to find out the secrets inside, but it took him years of hard work to finally create such a key that could barely open the door.

Dongfang Xiuzhe stood in front of this metal door, his yin and yang eyes were running at high speed, and after analyzing the "Formation Solving Technique" for a while, he secretly said with some sighs: "I really didn't expect that there are still composite formation groups hidden in the formations, and I don't know when I want to analyze these formations." ”

With his yin and yang eyes, he realized that this door could not be opened just by having a key. The slightest negligence can trigger the mechanism, so it's no wonder Flo is so cautious in the process of opening it.

Flo stood aside and prepared to watch how Dongfang Xiuzhe opened the door, at this time, seeing Dongfang Xiuzhe's solemn expression and a sad look, he hurriedly said: "How about it, there is no way, I just said, this is not a simple door, if it is so easy to open." I wouldn't have been so time-consuming and laborious back then, so I'd better continue the way I did. ”

Shaking the key in his hand, his face showed a little smugness.

Dongfang Xiuzhe had no intention of getting out of the way, and after a short silence, he suddenly said: "The ordinary method is no longer working, it seems that it can only be opened violently." ”

Flo looked stunned and asked strangely, "Are you planning to destroy it?"

"That's good!" Dongfang Xiuzhe nodded his head and looked directly at Flo, "If you don't have an opinion." I'm about to get started!"

Unexpectedly, Flo, who heard this, actually laughed: "It's useless, if it can be destroyed, why should I bother to get this key out of the time, effort and effort." ”

The key in his hand was the result of no less than 10,000 failures. When I think of my efforts back then, I still feel bitter now.

Fortunately, the discovery inside the door did not disappoint Flo and opened a new door to refining for him. Let him touch a higher level of refining.

Since Flo did not speak out against it, then Dongfang Xiuzhe could start unscrupulously.

A scorching flame burst out of his palm. Instantly, the temperature in the channel rises in a straight line.

Looking at Dongfang Xiuzhe's method of controlling the flames, Flo's old eyes suddenly lit up.

He was also lucky to be able to appreciate the "Fire Melting Technique" and "Alchemy" so closely.

Dongfang Xiuzhe's eyes released a sharp light, and without any hesitation, he controlled the flames in his palm and stamped towards the metal door that blocked the way.

"Poof!"

The result was a big surprise, the moment Dongfang Xiuzhe's palm touched the metal door, an incredible scene appeared, and the flames disappeared mysteriously.

Suddenly, Dongfang Xiuzhe was stunned on the spot.

This kind of thing has never happened before, and it is really incomprehensible.

What's going on, the fire melting technique and the alchemy technique have failed?

For a long time, Dongfang Xiuzhe maintained the same posture, as if recalling the details of what had just happened.

Flo's voice sounded next to him: "What do I say, this door is very strange, if the flame was useful to him, it would have been gone for a long time." ”

Dongfang Xiuzhe turned a deaf ear to Flo's words, and after thinking to no avail, he decided to try again, making sure to find out the reason.

The flames that emerged from the palms of his hands were even hotter, and with the blessing of the alien element "Red Lotus Flame", the temperature of the flames was still rising, as if it was about to ignite the entire passage.

Seeing this scene, Flo had to admire in his heart: "Such a powerful flame, if it is used in the process of refining weapons, it will definitely get twice the result with half the effort, tsk, I really didn't expect this young man to have so many amazing things." ”

The flame in Dongfang Xiuzhe's hand was once again imprinted on the metal door, and the result was the same as just now, the flame disappeared in an instant, as if a stone had sunk into the sea.

"How can this be?" Dongfang Xiuzhe opened his mouth in surprise.

Just now, he used the Yin and Yang Eyes to pay special attention, and it turned out that the formation inside the door had the ability to absorb flames.

He then tried five or six more times, but the flames disappeared abruptly.

"I really didn't expect to be able to encounter such a thing!"

After knowing that no matter how much he tried, there would be no results, Dongfang Xiuzhe finally stopped and stood up, and looked thoughtful.

This metal door is no longer able to melt with ordinary flames, and if you want to destroy it, you can only think of other ways.

At this moment, Flo muttered to herself: "It seems that if you want to melt this door, only the once every ten years 'Heavenly Fire' can do it, but unfortunately this door can't be moved, otherwise, I really want to melt it to relieve my anger." ”

"Tianhuo, what is that?" Dongfang Xiuzhe turned around with a curious expression.

"Why? You haven't even heard of 'Skyfire'?" Flo looked surprised.

Seeing that Dongfang Xiuzhe really didn't look clear, he sighed again and said, "Forget it, since you are curious, I can give you a brief introduction." ”

Coughing slightly, Flo walked in place, as if organizing the language.

"You must have heard of the 'Refining Ceremony' once every ten years, so do you know why the 'Refining Festival' is held every ten years?"

"Could it be that it has something to do with 'Heavenly Fire'?" Dongfang Xiuzhe's brows furrowed slightly.

"Yes, every 'Refining Celebration' is when 'Heavenly Fire' is born, and the real intention of the Refining Celebration is to gather aspiring refiners to draw out the 'Heavenly Fire' together, and then show their magical powers and borrow the power of the 'Heavenly Fire'. ”

At this, Flo paused, and a pair of eyes brightened, as if he was expecting something.

"Borrowing the 'Heavenly Fire' refining weapon, you said so much, I still don't understand what the 'Heavenly Fire' is?" Dongfang Xiuzhe frowned, already realizing that there seemed to be a big secret hidden behind this.

He had a feeling that if he could learn this secret, he might have something unexpected.

"'Heavenly Fire' is just an abbreviation for the people of this empire, in fact, it has many names, such as 'Earth Demon Flame', 'Samadhi True Fire', 'Melting the Lotus of All Things', etc., and some people call it an anti-heaven element!"

"Alien elements against the sky?" Dongfang Xiuzhe's body shook.

"It's really against the sky, every time you draw a fire from the sky, I don't know how many outstanding refiners die. Flo let out a long sigh.

"Tell me about this 'heavenly fire', why it only appears once every ten years, and where does it appear?"

Dongfang Xiuzhe asked with some excitement, as long as it was an alien element, he would be interested in capturing it, and the more against the sky, the better.

"It's a long story, so let's wait until you're inside, you can't waste a lot of time chatting. ”

Flo didn't want to continue the conversation on this topic, which made Dongfang Xiuzhe a little itchy.

And this may be the result that Flo wants.

Dongfang Xiuzhe originally planned to use his powerful destructive power to smash this metal door open, but at the moment of his attack, he suddenly changed his strategy again.

Before Flo could react to what had happened, a huge cavern appeared in front of him.

"This method is much simpler, this cave can lead directly to the inside!" Dongfang Xiuzhe jumped into the cave first.

Flo was stunned on the spot for a long time and didn't move, just staring at the cave that had been made out by Dongfang Xiuzhe in a daze.

"Smack!"

Flo actually slapped himself and muttered: "Why didn't I think of this method back then, it's really stupid!"

Jumping into the cave, Flo soon caught up with Dongfang Xiuzhe, who was one step ahead.

However, halfway through the journey, the unexpected happened.

The poisonous gas of the fragrance also came in out of nowhere, directly sealing the exit and entrance.

This kind of poison is really evil, Flo only took a small breath, and he felt that his whole body was weak, and there were faint hallucinations in front of him.

"It's not good, this poison can't be touched!"

Flo shouted, hurriedly stuffed a pill into his mouth, and transported the fighting qi to force the poison.

Fortunately, he was not deeply poisoned, and under the effect of the elixir, it took a lot of effort to finally force out all the toxins.

At this time, Flo was already sweating like rain, and what had just happened was as if he had walked on the edge of death.

Flo had to be afraid that even if he inhaled one more puff of this poison, the consequences would be unimaginable.

"What kind of poison is this, and how can the world still have ......?"

Before Flo could finish his sentence, his eyes widened in horror.

He was shocked to find that the fighting qi protection he had exerted was being weakened by this strange poisonous gas at an alarming rate. (To be continued......)
