"Hypoxic fire extinguishing method?"

Not everyone will pay attention to Yan Yuan's nonsense, but it is clear that Ruan Yin is not in the team that will not pay attention to Yan Yuan! She was very curious and asked, "What is the hypoxic fire extinguishing method?" ”

"To be precise, this trick is called suffocation fire extinguishing." Yan Yuan snapped his fingers, "The flame seems to burn out of thin air in the air, but in fact, it needs an accelerant, that is, the oxygen component in the air!" If the oxygen in the air is evacuated instantaneously, the air in this oxygen-deficient space will be extinguished instantly! ”

"Huh?" Ruan Yin was stunned, with scientific knowledge at the average level in the world, it was difficult for her to understand what the hell Yan Yuan's "oxygen" and "accelerant" were in his mouth, in fact, Yan Yuan himself didn't know anything about it, he just relied on the gourd to draw a scoop and copy his cheap father's statement as it was! He frowned, vaguely recalling his adoptive father's words, and continued with difficulty: "Remember...... Generally speaking, a large amount of carbon dioxide is used to expel oxygen to achieve the effect of isolating oxygen to extinguish fire and stop ignition. But, to be honest, I don't know what carbon dioxide is......"

"Carbon dioxide?" Ruan Yin repeated this strange word with difficulty, and then said with a big brain: "Isn't it two mutton made into meat flowers and grilled on top of the charcoal fire?" ”

"I ...... I don't think so, right? ”

"Haha! That's right! ”

Although Ruan Yin proposed a way to produce a large amount of carbon dioxide from a certain point of view, Yan Yuan and Ruan Yin themselves did not know about this matter, and naturally it was impossible to make any articles from it—even if they knew, this article was not very easy to write.

But Yan Yuan naturally couldn't have thought about anything, so he pretended to introduce his "new fire extinguishing method"! Because the principle of this suffocation fire extinguishing method is extremely simple, even if Yan Yuan can't get a large amount of carbon dioxide to expel oxygen, he can use this principle to extinguish the fire!

"If you can't drain the oxygen alone, then why not just drain the whole air out?!"

Facing Yan Yuan's sudden whimsy, everyone present was stunned, and Ruan Yin frowned first and shook his head very seriously: "It is difficult for the human body to survive in a vacuum environment!" There are still people in here! Ordinary people are afraid that they will not be able to support sixty breaths in a vacuum environment, and even a cultivator will be severely injured if he enters the vacuum environment without protection! ”

"You don't need to drain all the air in the entire Yamen Mansion, you just need to put out the fire a little bit!" Yan Yuan said with a smile, "After encountering someone and rescuing them alone, continue to extinguish the fire!" You and I can do it! It's just pumping out a portion of the space, you should be able to do it, right? ”

"I can." Ruan Yin nodded, turned his head to look at Xi Fan, "You can too, right?" ”

"I haven't tried it, but I guess it will." Xifan nodded, and then showed a wry smile, "Of course, I'm a little too weak now to be able to do it." ”

Ruan Yin is an existence at the peak level of the ground level, a cultivator of this level can completely influence the world with his will and soul, and it is not difficult for her to control the flow of air at all, and Xifan is also a high-grade existence of the ground level, even if he can't compare to Ruan Yin and some cultivators who can manipulate the weather, it is not difficult for him to drain the air in the limited area without interference!

However, this kind of thing is not difficult for the upper grade of the ground level, but it is not necessarily for Yan Yuan!

After Ruan Yin looked at Xifan, who was smiling bitterly, he looked at Yan Yuan with a frown, and asked with some uncertainty, "Can you do it too?" What are you doing? Aren't you just a low-level product? ”

The lower grade of the ground level has just opened the door of the spiritual world, and when it reaches the middle grade of the ground level, the spirit, will and soul can really affect the real world! Ruan Yin knew Yan Yuan very well, and as far as she knew, there didn't seem to be any moves in Yan Yuan's arsenal that could do this!

"Of course you can, you haven't really watched my special training on the Snow Wind!" Yan Yuan smiled evilly, and then took the initiative to walk towards the burning Yamen Mansion!

Ruan Yin looked at Yan Yuan, who was extremely confident, curiously, only to see that the pace under his feet was getting slower and slower, and his right hand was holding on the hilt of the gem knife, and the momentum on his body was also increasing little by little!

"Cold Spring, Midsummer, Golden Autumn, Warm Winter ......"

The words like self-hypnosis sounded, Ruan Yin was stunned, she still remembered what these words were—many of Yan Yuan's knife techniques needed to hypnotize herself by reciting poems to help her adjust her physical condition to the best state! And this sentence...... Remember the prelude to using the Instant Slash, right?

- But what is the use of the magical knife technique that can make time go against the current at this moment?! Could it be that he would be able to restore the building in front of him to the state it was in before the explosion and burned?! But didn't his instant slash only last for a few seconds to go against the current?

Ruan Yin frowned, but he didn't ask, just hugged his chest and quietly watched Yan Yuan's movements!

I saw that the pace under his feet was getting slower and slower, and the aura on his body was getting more and more dignified! The last time he used this instant slash, he hadn't been able to break through the spiritual portal and advance to the ground level! The hole cards that were forced out to avoid the attack of the Iron Heart Hunting Head! At that time, Yan Yuan had not completely completed this move, Wu Xian's moment could last so long, he could go back to such a distant past, and how could the moment slash he created through Wu Xian's moment be such a cheap move?!

The true perfection of this move can only be fully displayed until Yan Yuan reaches the Heavenly Level, but now its completion has gone further than that of himself!

“…… The journey of the four seasons flows backwards into a river in a blink of an eye. ”

A brilliant sword light slashed away in an instant against the raging flames of the flames!

Under the flickering light of the fire, it slowly retreated like a miracle, as if time had begun to rewind, the fire was quickly extinguished from the extreme, and the burned building was instantly restored to its original state!

"Oh my God! Mr. Yan, this and this, this ......"

In front of this miraculous scene, McDells was a little shocked and incomplete! And Wu Lei and Xifan, who were also seeing the instant slash for the first time on the side, were also stunned to see Yan Yuan's magical slash! Both of them are members of the Six Gates Headquarters from the capital, and they are naturally extremely familiar with the incident of the God of Humanity in the capital that was hyped up more than a month ago! (Although Wu Lei did not participate in the prelude and afterplay of the God of Humanity incident because of some "accidents", he at least read the intelligence file!) At this moment, Xifan suddenly realized that this move was similar to the knife that played with His Highness the Chief Catcher that day......

- That bloody rose is really Yan Yuan! Damn, that guy really guessed right?!

Obviously, the information of the six doors for Yan Yuan was originally only obtained from His Majesty the Emperor, "This man is good at disguise, especially likes women's clothes", and they didn't know that Yan Yuan was the bloody rose who "played with an iron heart and always caught his head" and "rode alone into the Forbidden City"! However, Yan Yuan didn't know this, he also thought that all his information had been sold to Six Doors by Cui Ang, so he naturally had no worries about making a move at this time!

I saw him stretch out his hand to the small part of the building that had been restored to its original state, then fanned his palm, sniffed the "strange and fishy water vapor", and then said with a subtle expression: "It's really gasoline......

"Yan Yuan, can you go back so long ago?"

"Well, you can locate the past within a stick of incense, but it can only affect inorganic matter." Yan Yuan smacked his lips and moved his right arm holding the knife, and then the effect ended in an instant, and the restored building burned again in an instant! "Now that it's decided, let's get started!"

Then he raised his hand and pointed the magnificent gem knife in his hand at the raging fire! His eyes revealed a strange light, and the fate of cause and effect suddenly opened, and while slowly inputting his true qi into the long knife in his hand, he explained to the people around him: "I am indeed still a low-level grade, and I really can't use my spirit and soul to affect the real world when I stay in this realm, but my special ability Karma can help me see all the details of this real world, and my soul can help me better control my power!" Yes, I can't affect the real world with my soul, but I can do it in a real way! ”

"The way it actually exists...... No way? Why don't you plan to ......" Ruan Yin was the person who knew Yan Yuan best in the end, she was stunned for a short moment, and then reacted quickly, casting her eyes on the long knife in Yan Yuan's hand, her face suddenly fell, and she shouted with residual thoughts: "Mom, I thought you were going to take out some amazing and glamorous moves!" Didn't you break the bottom all of a sudden?!

Yan Yuan ignored Ruan Yin's strange words, and thought that this girl was jealous that she had such an excellent and all-powerful weapon! I saw him staring at the part of the building in front of him that needed to be extinguished while running the karma and staring at the gem knife in his hand waving there! A cyan gem on the gem knife shone brightly, and as this gem flickered, the air next to the blade gradually flowed!

In other words, Yan Yuan's so-called method of "draining the air" used the gem knife in his hand as a magic staff, and used the gems inlaid on the gem knife as a spell casting medium to release a spell to create a vacuum on the designated area! He couldn't do this before, but after being promoted to the lower rank of the earth, his spiritual power increased greatly, so much so that he could completely control the five elements with the help of the gem knife, so as to cast some original spells!

To be honest, the forcing is a bit low......
