Why do we say that ordinary heroic spirits are arbitrary for eternity?

Chapter 49 The legend of the one-handed lightning technique spreads! (Seeking for further reading)
  that day.

The great virtuous master asked Lu Yu what reward he needed for such a heavenly achievement.
  Lu Yu said without thinking that he wanted to learn talismans and thunder techniques!
  When these words were spoken, everyone fell silent.

No one thought that this young man was so simple and believed in such things as talismans and thunder methods.

At that time, everyone wanted to laugh, but did not dare to laugh out loud.

Because the righteous master Zhang Jiao is here. If anyone dares to laugh, they can pack their things.

Later, when everyone heard the conversation between Lu Yu and Han Zhong, they realized that Lei Fa was just an excuse, and his real intention was to become a disciple and become the ninth direct disciple of the great sage!
  In this way, things become reasonable.

Lu Yu could develop a magic medicine to cure the plague, how could he believe in talismans and thunder methods?

How could Fu Lu and Lei Fa be real?
  At least... that's how it was viewed at the time.

But here we are today.

Everyone looked at the explosion in front of them, heard the deafening thunder, and looked at the mushroom-shaped smoke, and they were all shocked.

Rafa!

The ninth direct disciple of this great virtuous master has actually learned the thunder method? !
  And in just a few days, he has already reached the level of Dacheng!
  This kind of talent is truly unprecedented and unprecedented!

Even Tang Shigui, who had spent a lot of time with Lu Yu, was stunned by the scene in front of him.

This scene was completely beyond his cognition.

After the violent explosion, the scene became very quiet. No one dared to speak casually, for fear of angering Lu Yu and being struck by lightning!
  Even people like Qu Shuai Zhang Mancheng have become cautious.

He had been dissatisfied with Lu Yu before and felt that Nanyang should not have a second Qu Shuai.

But now, Zhang Mancheng's face has turned blue. Even though he has achieved great mastery in martial arts and can be regarded as a top master, who can withstand this rolling thunder?
  I can’t stand it, I really can’t stand it!

Lu Yu looked at the explosion effect in front of him and nodded with satisfaction. Listening to Zhang Mancheng's words, he knew that he had misunderstood.

This is normal. Although gunpowder originated in the Spring and Autumn Period as an unexpected product of alchemy, it would have to wait until the Sui and Tang Dynasties for gunpowder to be truly popularized and applied, and even appear on the battlefield.

At this moment, he got the gunpowder out in advance, and it was a perfectly matched gunpowder. He even got the explosive pack directly and blew up the boulder!
  In this situation, it is naturally impossible not to shock everyone.

But what Lu Yu wants is this shocking effect!
  If we don't broaden everyone's horizons and let them realize the power of this new thing, how can they be taken seriously?

Lu Yu shook his head and said, "This is not a thunder method."

Zhang Mancheng frowned and asked, "Why is that?"

Lu Yu explained: "This is the power of gunpowder!"

"Gunpowder?" Zhang Mancheng felt that this word was a bit new and waited for Lu Yu to continue explaining.

Lu Yu said with a smile: "Fan Li, the Shang sage, once wrote "Fan Zi Ji Ran". The book said: 'Saltpeter comes out of the Long Road', 'Combine saltpeter with sulfur and realgar, and mix it with honey. Burn it.' 'When the flames rise, it will burn your hands and face.'" And burn down the house'."

"Some alchemy techniques from earlier periods also recorded gunpowder formulas, but they were too incomplete."

"I extracted various recipes, improved them, and studied them for several days, and finally got the best ratio of gunpowder."

"The thunder that hit the ground just now was the explosive effect caused by a sufficient amount of gunpowder being ignited."

"My cooperation with Zhang Shuai is this gunpowder."

After listening to Lu Yu's story, Zhang Mancheng realized that it was really not Lei Fa.

Zhang Mancheng quietly breathed a sigh of relief, wiped the sweat from his forehead without leaving any trace, and said calmly: "This thing can be used to dig mountains and quarry rocks, and even attack cities and lands. Who can stop it under the thunder of heaven? However, With such power, it would probably cost a lot of money to produce..."

"That's not the case." Lu Yu shook his head slightly and began to explain this gunpowder industry to Zhang Mancheng in detail!
  Because it involved confidentiality, his voice was not loud, and only Zhang Mancheng, who was nearest, could hear clearly.

The ratio of gunpowder is the key, and the raw materials are even more critical.

The output of folk method of making saltpeter is very low.

If you want to produce in large quantities, you must go to deep mountains, old forests, caves and dangerous places to search for raw materials, and then extract the output through cooking.

The nitrate thus produced is usually very pure nitrate.

In addition, in addition to nitrate, you will also get a by-product, salt!     As long as you find a way to sell the salt, you can make a lot of profit.

As for the more precious saltpeter, all of it is naturally saved and does not need to be sold at all.

As for the source of sulfur, because it is rare to find high-purity sulfur ore, it is usually pyrite, also known as pyrite.

Taipingdao can be blasted with gunpowder and then refined on a large scale.

In this way, not only sulfur can be obtained, but also by-product iron and some associated ores can be obtained.

As long as there is enough iron, Taipingdao's equipment and weapons will be greatly upgraded.

There is no need for Lu Yu to explain the benefits and benefits this can bring.

Of course, there are risks as much as there are benefits.

Salt and iron were a project exclusively owned by the imperial court.

Selling private salt is a serious crime and will cost you your head. As for privately mining iron ore, this is even more of a game for the Nine Tribes!
  Once discovered, the consequences are unimaginable!
  Zhang Mancheng was so frightened by Lu Yu's business deal that he kept blinking his eyelids.

"Lu Qushuai, you are too courageous." Zhang Mancheng couldn't help complaining: "Young people are really not afraid of death."

Lu Yu shook his head and said, "It's not that I'm not afraid of death, brother, but the time is about to come."

"You mean..." Zhang Mancheng was stunned and said subconsciously: "It won't be so fast."

"Originally, it wasn't so fast, but because I developed a medicine that can cure the plague, Taipingdao's sermons have become faster. I'm afraid this process has been greatly accelerated." Lu Yu explained: "So, leave it to us Time is running out, we must move faster, even if this move is a little bolder."

As soon as these words came out, Zhang Mancheng was silent for a moment, but did not refute again. It was obvious that he agreed with Lu Yu's view.

Zhang Mancheng pondered for a while, thought for a while and said: "I will release the news, saying that the ninth direct disciple of the Great Master of Taiping Dao is extremely talented. In just a few days, he has achieved great success in thunder skills..."

"The explosion caused by the pyrite mined by gunpowder is all credited to you. It was you who was using the thunder method."

"how do you feel?"

Lu Yu thought for a while and nodded: "Okay!"

The shadow of the famous tree, if these news really spread, it is not entirely a bad thing.

And if this kind of news is true or false, just when everyone thinks it is false, Lu Yu may be able to show off his real thunder skills!

In fact.

There is no need for Zhang Mancheng to specifically promote it.

So many people at the scene saw this scene with their own eyes and heard the deafening explosion, and since Zhang Mancheng and Lu Yu did not give orders not to tell anyone, everyone would naturally regard today's incident as a source of conversation.

This kind of thing, whether it is bragging while drinking, or bragging vividly after dinner, is very honorable!
  They have seen the big scene and witnessed the existence of Leifa!
  The legend about Lu Yu's thunder skills spread rapidly, spreading from one to ten and then to one hundred.

The people behind also added all the details of this story.

"That day, the great virtuous master came to Nanyang in person and saw Lu Yu, the god of medicine. He secretly marveled at his unique talent and was moved to accept him as a disciple on the spot."

"He decided to test Lu Yu first. He first transformed hundreds of thousands of taels of gold, then hundreds of stunning beauties, and finally gave Lu Yu a book of lightning techniques to choose from."

"How can the God of Medicine Lu Yu be mediocre like us? He didn't even look at anything else, and without any hesitation, he directly chose Thunder Method!"

"In fact, if you choose the other two, it will be all in vain!"

"The Great Master was very pleased. He accepted him as his ninth personal disciple and taught him his unique thunder method."

"That Medicine God Lu Yu is truly a gift from heaven. He has mastered the Thunder Technique that others have not been able to learn for decades, but he has mastered it in just a few dozen days!"

"On this day, he invited Zhang Qushuai to visit the thunder method. He recited the words, "Lei Gong helps me, pinch it with his hand, stretch out his finger!"

"Unexpectedly, the boulder weighing millions of kilograms was hit by a thunderbolt and exploded into pieces in the blink of an eye. That scene..."

The story became longer and longer, with more details, and with Zhang Mancheng adding fuel to the flames, soon almost the whole of Nanyang knew about it!
  The legend of Lu Yu, the god of medicine, who is good at thunder magic has spread completely!
