Huan Dan laughed, his footsteps getting farther and farther away from his laughter.

Luo Shixin's eyes were closed, and he didn't know what the situation was with this fire escape technique, but he smelled a stench of burning carbon nitrate, Huan Dan's strange behavior at this time, and also in his senses, he couldn't help but be secretly shocked, and his heart shouted: "It's not good!" "He made a fatal mistake.

He has absolute confidence in his martial arts, and has a strong interest in the mysterious and unpredictable Five Elements Escape Technique, which is also the cause of this battle. But the belligerent man overlooked the fact that there was no need for Huan Dan to fight against him. As long as he escapes with the "smelting experience" and escapes from his control, he will be able to achieve his goal.

With the help of the principle of refraction of light, Jin Dunshu blocked Luo Shixin's line of sight, forcing him to go blind and escape.

"Bastard!"

Luo Shixin scolded secretly and opened his eyes, but there was a vast expanse of smoke around him, and the visual range was only a stone's throw away, and he rubbed his eyes: when he opened his eyes, his eyes, which had not yet recovered from stinging, were attacked by thick smoke again, and they were jerky and uncomfortable.

"Shame on you!"

Thinking in his heart, Luo Shixin was trying to rush out of the smoke circle with his head bored, looking for the direction of Huan Dan to catch up.

As soon as he took a step forward, the Luo Shi believer felt a strange feeling, held his breath and condensed, transcendent and outside, the long knife cut through the sky, and slashed towards the left hand side.

This knife is silent, fast or fast, slow or slow, plain, but it gives people a feeling of full strength. According to the common theory, the harder you push, the faster you will go, and vice versa. Luo Shixin's knife violates the principle of mechanics.

"Huh!" There was a cry of horror from the mist.

The knife turns faster in an instant!

In an instant, the cry of horror turned into a miserable cry, and the whole body flew upside down out of thin air. Thick smoke rushed out, and there was a "pop". He fell heavily to the ground.

Luo Shixin secretly pinched a cold sweat, if he hadn't reacted in time. I'm afraid that Zhonghuan Dan's calculations will really suffer at his hands.

Huan Dan didn't plan to escape at all, but thought about the playing tactics from the beginning. He knew that he was far from being Luo Shixin's opponent, and he fought with real swords and guns, and had almost no chance of winning, so he could only outwit him. deliberately made the illusion of escaping, forcing Luo Shi to be anxious and not care about anything else, and hurriedly pursued, so that he had a successful sneak attack on the side.

"Beautiful!" Luo Shixin pinched a cold sweat. gave a very high evaluation to Huan Dan's play: from the beginning, he was setting up the game until he was led into the urn. This calm and resourceful mentality is truly remarkable.

Covering his mouth and nose, Luo Shixin strode out of the smoke area, Huan Dan received a blow from Luo Shixin, although he was merciful to his subordinates, but he also suffered a lot of trauma, and he couldn't get up for a while.

"I ...... Hiss, lost! Huan Dan had a sharp pain in his chest. It was a little difficult to speak, and he took out the smelting experience from his arms gloomily and threw it away to Luo Shixin.

Luo Shixin carefully stretched out his hand to take it and put it in his arms. Glancing at the smoke that had dissipated behind him, a small crater appeared not far from him, and the surrounding exploding dirt and fallen leaves were everywhere.

Look at the scene clearly. Luo Shi's confidence moved, and he exclaimed: "This is black powder? ”

Black powder is one of their four great Chinese inventions. It was a revolutionary prelude to war, precisely because of the emergence of black powder. Only then did the firearms and even the guns in the back make the cold weapons begin to transform into hot weapons. However, he has the impression that black powder first appeared in the late Tang Dynasty and was invented by alchemists. From the Warring States period to the early Han Dynasty, the emperors and nobles were intoxicated with the fantasy of immortality, and drove some monks and Taoists to refine the elixir, and they inadvertently invented it with saltpeter sulfur, the main ingredient of black powder.

"What black powder?" Huan Dan was confused.

Luo Shixin said: "I am friends with the girl in Tsing Yi in life and death, and I also learned the key meaning of the Five Elements Escape Technique from her. Jin Dunshu has already seen it...... I take the liberty of asking, what props are borrowed from this fire escape technique? Sulfur saltpeter, or what? ”

Huan Dan looked surprised, and said after a moment's silence: "I didn't expect Lord Shangshu to be so knowledgeable...... This is a matter of my Five Elements Sect's secrets, and I can't say the details. I don't know what the principle is, so I'll just tell you something. In the early years of the Sui Dynasty, a Taoist priest named Du Chunzi went to visit an old man who was alchemist. Stayed there that night. In the middle of the night, Du Chunzi woke up from a dream and saw a large amount of purple smoke suddenly coming out of the alchemy furnace for no reason, piercing the house, and sparks were ignited. Du Chunzi is an ancestor of my Five Elements Ancestor, he used this as a study, drawing on the research experience of his ancestors in Danshu, and found that sulfur, nitrate, and carbon can constitute a very flammable medicine, and mixing some key things from it can raise a large amount of dust and mist, obstructing people's vision. ”

As a descendant, Luo Shixin easily understood what Huan Dan said, and sighed: "The name of hidden killing is worthy of its name!" You started walking with your feet on the floor, and every step made a loud noise, which made me think it was your unique footwork, but you were already laying it out. Then you borrowed the golden escape technique to seal my eyes and force me to close my eyes and fight. This is the second layout, and then use the fire escape technique to create a smoke sound, pretending to escape. Your steps were heavy, and the sound of your footsteps was suddenly gone, giving me the feeling that you had gone far away. In fact, the way you have changed your walking, you have made a light way to go around to my left, intending to surprise me with a fatal blow. The girl in Tsing Yi described it appropriately, the Five Elements Escape Technique is actually the Five Elements Eye Blocking Technique, but playing this Eye Blocking Method to the extreme, playing to the point that the weird Cheng dù is magical, it becomes an illusion Escape Technique. ”

De Luo Shixin praised him so much, and Huan Dan was also proud, but then he looked gloomy: "It's a pity that in the end, the general still saw through it." ”

Luo Shixin said: "That's because the blinding method is always a blinding method, and I was really confused at first, but I can think about it. In order to prevent your strange Five Elements Escape Technique, I specially chose this place where there is no terrain around you to hide and use. A clever woman can't cook without rice, and there is no place to cover, how can your Five Elements Escape Technique exert its power? How far can you escape in a short moment? Therefore, I judge that you have not left, and everything is your calculation. ”

Huan Dan said bitterly: "What the adults said is right, what is fake is always fake...... My Five Elements Sect is looked down upon by the Daomen, just because every qiē is fake, bluffing things. ”

"Can't say that!" Luo Shixin said: "Maybe in the eyes of people, the means you have mastered are a trick to deceive people, but in my opinion, it is science, the most real and real thing. The Golden Escape Technique uses the principle of refraction of light, and the Fire Escape Technique uses the knowledge of chemistry. Don't ask me what chemistry is, I can't tell you clearly, but you must know that if you continue to develop this skill, it will achieve value and significance across the ages. As for the wooden shield, water escape, and earth escape, I have never seen it, and I don't know the reason, but I am sure that there must be a sense of meaning. In fact, I personally feel that if you want to revitalize the Five Elements Sect, there may not be only one dead end. He pointed to the hole in the ground and said, "This is the power of your fire escape technique, have you thought about it?" You've developed something that can blow a small hole in the ground. What if this fire escape technique blew up not a small pit, but a huge deep pit? ”

"How is this possible?" Huan Dan listened attentively, the Five Elements Sect belongs to the sect, Zhang Daoling's ghost sect branch, but their status in the Dao sect is a liar, and they have always been despised by their peers. It is precisely because of this that Huan Dan, who was cold-eyed in Longhu Mountain, would be so persistent in revitalizing the Five Elements Sect. Luo Shixin did not discriminate against the skills of the Five Elements Sect, but praised him greatly, which made him particularly moved. But Ro's words were beyond his comprehension, and he really couldn't imagine that the smoke bombs they had invented would be so powerful.

"Why can't it be?" Luo Shixin was a little saddened, China has many cultures that once surpassed the top of the world, because of the lack of open-mindedness and limited restrictions, and in the end it was surpassed by the West. A clear example of this is black powder, an invention of the Tang Dynasty that could change the pattern.

However, because although the alchemists who invented black powder mastered certain chemical methods, their direction was to seek the elixir of immortality, so the invention of black powder had a certain degree of chance. It was not taken seriously, and for a certain period of time it became an acrobatic performance of the circus of the armies, as well as a prop for fireworks acrobatics in puppet shows.

It was not until the Song Dynasty that gunpowder was used in large quantities in military affairs, and the Song Dynasty also became the first country in history to use "hot weapons", but unfortunately in the course of the war with the Song, the Jin and Mongols also learned the use and production of firearms. The Mongols were defeated in the war against Syria, and the Arabs seized gunpowder weapons such as rockets, poison canisters, artillery, and earth-shattering thunder, thus mastering the manufacture and use of gunpowder weapons.

As a result, gunpowder was introduced to Europe and became one of the important pillars of the European Renaissance.

As a traverser, Luo Shixin knows the power of thermal weapons, but it is useless, he has never been exposed to this knowledge, he can't make sulfur saltpeter and other messy things, let alone rockets, poison fire cans, artillery, and earth-shattering thunder.

The times need a process of progress, not seedlings to grow.

As a time-traveler, he believes that he can promote the progress of this era, and without arrogance, he will come to a great leap forward, and directly ascend to the age of steel.

Now Huan Dan's fire escape technique made him see the emergence of an opportunity.

Luo Shixin said: "In the Xia Shang Dynasty, did you ever think that there were iron tools that were harder than bronze? In the Qin Dynasty, who ever thought that there would be steel tools that cut iron like clay? Times are advancing, and nothing is impossible. You can use a little thing to make such a terrible smoke, and you can blow a small hole in the ground, why don't you want to think about blowing a hole out of this place? (To be continued......)
