Huan Dan laughed loudly, his footsteps getting farther and farther away.

Luo Shixin's eyes were closed, and he didn't know what was going on with this fire escape technique. He just smelled the stinking smell of carbon and nitrate. Huan Dan's strange behavior at this time was also in his senses. He couldn't help but be shocked and shouted: "No!" He made a fatal mistake.

He had absolute confidence in his martial arts and had a strong interest in the mysterious and unpredictable Five Elements Escape Technique, which was also the cause of this battle. But he was warlike, ignored one thing that Huan Dan had no need to fight with him. As long as he escaped with his "smelting experience" and escaped from his control, he could achieve his goal.

With the help of the refraction principle of light, the Golden Escape blocked Luo Shixin's sight, forcing him to blindness and escape.

"asshole!"

Luo Shixin cursed inwardly and opened his eyes, but there was a vast area around him, with smoke, and the visible range was only a short distance away. He rubbed his eyes: When he opened his eyes, his eyes, which had not recovered, which had not recovered, were attacked by thick smoke again, which was awkward and uncomfortable.

"It's so embarrassing now!"

Thinking of her mind, Luo Shixin was about to rush out of the smoke circle and chase after Huan Dan in the direction he was away.

Just as he took a step forward, Luo Shizhe felt strangely, held his breath and focused, and detached from the object. The long sword cut through the sky and slashed towards his left hand.

This knife is silent, saying that it is fast or not, slow or slow, it is dull, but it gives people a feeling of full strength. According to the theory of constant theory, the more force it is, the faster the speed is, the slower it is. Luo Shixin's knife violates the principles of mechanics.

"Huh!" A horrifying cry came from the fog.

The knife instantly turned faster!

In the flash of lightning, the horror turned into a miserable cry, and the whole body flew backwards out of thin air, and thick smoke rushed out. With a "click", it fell heavily to the ground.

Luo Shixin secretly broke into a cold sweat. If he hadn't reacted in time, he would have to have Zhong Huan Dan's plan and would have suffered a loss at his hands.

Huan Dan had no intention of escaping at all. Instead, he had thought of a tactic of playing from the beginning. He knew that he was far from Luo Shixin's opponent, and he had no chance of winning when fighting with real swords and guns, so he had no chance of winning, so he could only win with wisdom. He deliberately made the illusion of escaping, which forced Luo Shixin to be anxious and not care about anything else and pursued hastily. This made him have a side-strike successfully.

"Beautiful!" The man Luo Shixin was sweating coldly, and gave a very high evaluation of Huan Dan's move: from the beginning, he was setting up a plan until he was trapped in the trap. This kind of smart mentality of being calm and appropriate in dealing with things is indeed amazing.

Covering his mouth and nose, Luo Shixin strode out of the smoke area. Huan Dan was hit by Luo Shixin. Although he showed mercy, he was also suffering a lot of trauma and could not get up for the moment.

"I... hiss, I lost!" Huan Dan's chest was so painful that he was a little difficult to speak. He took out his smelting experience from his arms and threw it from Luo Shixin from afar.

Luo Shixin carefully reached out to take it. He put it in his arms and looked at the smoke that dissipated behind him. A small hole appeared not far away. The surrounding areas were full of broken mud and broken leaves.

Seeing the scene clearly, Luo Shixin moved his heart and exclaimed: "Is this black gunpowder?"

Black gunpowder is one of their four great inventions in China and is the prelude to the transformation of war. It is precisely because of the emergence of black gunpowder that there are firearms and guns and cannons that lead to the transformation of cold weapons to hot weapons. However, in his impression, black gunpowder 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 immersed in the fantasy of immortality and immortality, and drove some alchemy priests to refine elixirs. They invented it inadvertently with the main component of black gunpowder, saltpeter sulfur, as medicine.

"What black gunpowder?" Huan Dan looked confused.

Luo Shixin said: "I am a friend of life and death with the girl in Qingyi. I also learned the key secrets of the Five Elements Escape Technique from her. I have already seen the Golden Escape Technique... I took the initiative to ask what props did this Fire Escape Technique borrow? Sulfur saltpeter, or what?"

Huan Dan looked surprised and pondered for a moment: "I didn't expect that Lord Shangshu is so knowledgeable... This is related to the secrets of my Five Elements Sect, and I can't tell you the details. I don't understand the principle, so let's talk to you. In the early years of the Sui Dynasty, a Taoist priest named Du Chunzi visited an old alchemy man. He lived there that night. Du Chunzi woke up in his dream in the middle of the night and saw a large amount of purple smoke suddenly popping out of the alchemy furnace for no reason and sparks ignited. Du Chunzi is a ancestor of my Five Elements Sect. He used this as a research and borrowed the experience of his predecessors' alchemy research. He found that sulfur, nitrate, and carbon can form an extremely flammable medicine. If some key things are mixed into it, it can raise a large amount of dust and mist and block people's sight."

As a later generation, Luo Shixin easily understood the knowledge Huan Dan said, and sighed: "The name of hidden killing is well-known! You started walking with your feet and made a huge sound every step, which made me think that this was your unique footwork, but in fact you were already planning. 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 used the Fire Escape Technique to create the sound of smoke and pretend to escape. Your steps were heavy, and your footsteps were gone at once, which made me feel like you had already walked away. In fact, you have changed your walking method, and used the light body method to get around me, intending to give me a fatal blow unexpectedly. The girl in blue described it just right. The Five Elements Escape Technique is actually the Five Elements Escape Technique, but playing this trick to the extreme, and playing it to the level of superb weirdness, it became an illusion escape Technique."

When Luo Shixin praised this, Huan Dan also looked proud, but then he looked sad again: "It's a pity that the general was able to see through it in the end."

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

Huan Dan said bitterly: "What the lord said is right, false things are always false... My Five Elements Sect is looked down upon by the Taoist sect because everything is false and is a bluffing thing."

"You can't say that!" Luo Shixin said seriously: "Maybe in the eyes of people, the method you master is a trick of fooling people, but in my opinion it is a science, the most real thing. The golden escape technique uses the principle of refraction of light, and the fire escape technique uses chemistry knowledge. Don't ask me what chemistry is, I can't explain it clearly to you, but you must know that if the technique you master continues to develop, it will achieve value and significance across the era. As for the wooden shield and water escape,

I have never seen the earth escape, I don’t know the reason, but it is certain that there must be a meaning. In fact, I personally think that if you want to revitalize the Five Elements Sect, there may not be only one dead end to you." He pointed to the pit on the ground and said, "This is the power of your fire escape technique. Have you ever thought about it? The thing you developed can blow a small pit on the ground. If the fire escape technique is not a small pit, but a huge deep pit, what is the situation?"

"How is this possible?" Huan Dan was so enchanted. The Five Elements Sect belonged to the sect and Taoist ranks, and Zhang Daoling's Ghost Dao branch, but their status in the Taoist sect is a liar and has always been despised by his fellow disciples. It is precisely because of this that Huan Dan, who was cold-eyed in Longhu Mountain, was so persistent in revitalizing the Five Elements Sect. Luo Shixin did not discriminate against the Five Elements Sect's skills, but he was particularly moved by praise. However, Luo Shixin's words were beyond his scope of understanding, and he could not imagine that the smoke bombs they invented would have such power.

"Why is it impossible?" Luo Shixin felt a little sad. Many of our cultures in China have been above the world because of their lack of openness in their minds and limited limitations. In the end, they made the West surpass it. Black gunpowder is an obvious example. Black gunpowder was an invention invented by the Tang Dynasty that could change the pattern.

But it is because the alchemists who invented the black gunpowder mastered certain chemical methods, but their direction was to seek immortality. Therefore, the invention of the black gunpowder was a certain accident. It was not taken seriously and became a prop for the acrobatics of the military circus and the fireworks acrobatics in the puppet show for a certain period of time.

It was not until the Song Dynasty that the gunpowder was used in large quantities in military use. The Song Dynasty became the first country in history to use "hot weapons". Unfortunately, during the battle with the Song Dynasty, the Jin and the Mongols also learned to use and make firearms one after another. Mongolia was defeated in the battle with Syria, and the Arabs seized gunpowder weapons such as rockets, poisonous fire pots, artillery, and thunder to master the manufacturing and use of gunpowder weapons.

Gunpowder was also introduced to Europe and became one of the important pillars of the European Renaissance.

As a time traveler, Luo Shixin knew the power of heat weapons, but he knew it was useless. He had never been exposed to this knowledge. He could not create sulphur saltpeter or any messy things, let alone rockets, poisonous fire pots, cannons, and thunder.

The times need a progressive journey, not to encourage growth.

As a time traveler, he believes that he can promote the progress of this era. Without arrogance, he will directly elevate to the Iron Age.

Now Huan Dan's fire escape technique has allowed him to see the opportunity.

Luo Shixin said: "During the Xia and Shang dynasties, did you think of iron tools that are harder than bronze? During the Qin dynasties, did you think of steel tools that are as sharp as mud? The times are progressing, and there is nothing impossible. You can use a little bit of small things to make such terrifying smoke and blow a small hole into the ground. Why don't you think of blowing a hole into the ground?" (To be continued)
