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

Chapter 29 Heavy rain, big plan to make a fortune!
  Before, Lu Yu had no money and no one, so he could only focus on cultivation without having many ideas at all.

Now I have some spare money and some subordinates. Although they are not many, they can at least do something.

For example, by clicking on the technology tree, you can create some products that are ahead of the times, earn more profits, have more funds and influence, and can do more things.

Lu Yu had no intention of hiding his clumsiness.

When he first joined Taiping Dao, he had a humble status, no connections and no influence. No matter what he did, he needed to think ahead and think again.

Nowadays, he has a small foundation, and there is no need to restrain his hands when doing things.

In fact, as an ordinary person.

Lu Yu didn't know much knowledge and was originally unable to engage in scientific research and development in ancient times.

But he was summoned to the future as a heroic spirit.

Although the only things that can be brought back are spiritual stones for cultivation, nothing else can be brought back.

However, the knowledge gained from the future can be firmly remembered and brought back!
  It is not a bad idea to use this method to develop science and technology in ancient times!
  Take advantage of items that were ahead of their time.

Whether it is to make a fortune, expand your influence, or strengthen your own power, it will become very simple.

After you become rich and powerful, it will be much easier to find the true method to practice.

Now, all we have to do is wait for Bai Yuyao to call again.

Due to the time difference, more than a month has passed here, and she has not yet summoned again.

Lu Yu was not strong enough to take the initiative and could only wait slowly.

‘Crackling…’

'Crash...'

The heavy rain was like broken beads, crackling on the roof and the blue bricks on the ground, causing splashes of water.

The rainwater flowed down the eaves again, like a waterfall, and gradually gathered into a puddle in the courtyard.

There is so much water that it cannot be drained away. The street outside has turned into a creek. I heard that many people's homes have been flooded.

Lu Yu's residence is on a higher ground, so this situation has not happened yet.

Lu Yu glanced at the gloomy sky, looked at the dense rain, and couldn't help but sigh.

"It's been raining for a month, and it still hasn't stopped."

Since the bandits came back last time, the rain has started to fall intermittently. I thought that after a long drought, God would finally give the people a way to survive.

Who would have thought that the sky felt like a hole had been drilled through it? The rain had not stopped since it began, and it was getting heavier and heavier. Many places had already suffered from waterlogging.

First came the drought, then the flood. It is really difficult for the people these days. It is really dire straits.

The rain kept falling, making people a little irritable.

Lu Yu had nothing to do and could only practice in the house with his head covered.

His cultivation level is too low now, he doesn't even have the second level of Qi training, and his mastery of the secret technique of Feng Shui is also progressing slowly. The only thing that makes him happy is that he is making rapid progress in martial arts.

Over the past month, Lu Yu's progress in martial arts has been almost as fast as the naked eye.

According to Master Ruan, one month of effort can take several years longer than others!

I don't know if Lu Yu has talent in martial arts, or because he is cultivating immortality and feeding martial arts back, which leads to extremely rapid progress.

Lu Yu felt that it might be both.

While Lu Yu was practicing, he suddenly felt something.

He couldn't help but smile slightly.

"coming."

Just like last time, it took a month, and finally I waited for the call again.

……

In Bai Yuyao's boudoir.

There are various delicacies on the table.

There were a lot of things she liked to eat, and she thought Lu Yu would definitely like them, so she personally ordered the kitchen to prepare them.

A phantom slowly reappeared. This time, Lu Yu didn't change much, not much different from a month ago.

"You're here, I've prepared a lot of delicious food for you!"

Looking at her heroic spirit, the little rich woman had a smile on her face.

Lu Yu nodded, glanced at the delicious food on the table, and looked at the smile on the little rich woman's face. For some reason, he felt much more relaxed.

"I need to ask you to help me collect some information." Lu Yu said directly.

"What information?" Bai Yuyao asked curiously.

Lu Yu thought for a while and then said: "I need a book called Tiangong Kaiwu. You can help me find it. If I can't find it, I can collect some technological products that can be manufactured manually before the spiritual energy is revived. "

"Tiangong creates things?" Bai Yuyao listened to the name of the book and the words behind it, but for a while she couldn't understand what Lu Yu wanted to do.

But since it was Lu Yu's request, Bai Yuyao didn't ask any more questions and just nodded in agreement. "okay, I get it!"

"You should eat first and try the food this time. There are a lot of things I like, and I think you should like them too."

"I'm going to collect this information now."

"Okay." Lu Yu couldn't help but move his index finger as he looked at the delicious food in front of him.

Although after becoming the deacon of Taiping Road, he has a million-dollar fortune and can eat a lot of good food, but in terms of the taste of the food, it is definitely not as good as the delicacies prepared by the little rich woman!
  Lu Yu picked up a fried shrimp and bit into it. The shrimp shell was fried to a crispy texture and could be chewed directly.

Bai Yuyao also began to collect information in this area for Lu Yu.

Because she didn't know much about this, even if she found information books on this, she couldn't tell whether it was true or false.

If fake goods are given to Lu Yu, that will definitely not work!
  However, although I don’t know this knowledge.

But Bai Yuyao clearly understands one truth, that is, professional things should be done by professional people.

Not everything is best if you do it yourself.

Bai Yuyao immediately used her connections to contact several scholars specializing in ancient times and presented her requirements to them.

Although these ancient research scholars are very curious about what the eldest lady of the Bai family needs these information for, is she playing in the wilderness to survive?

But they still tried their best to collect it, and at the same time, they had to ensure the authenticity of the information.

After a while, some information came one after another.

"Come over and take a look to see if this is the information you need." Bai Yuyao turned her head and glanced at Lu Yu, smiling.

"Okay." Lu Yu immediately floated over after hearing this.

On the clear light screen in front of you, there are modern technological products that can be built in ancient times.

[Saltpeter Ice Making Method]

[Purification of coarse salt]

【Soil cement】

【Soap Making】

[Production of transparent glass]

【…】

Lu Yu looked at the information in front of him seriously.

The first one is a bit unreliable.

Making ice from saltpeter may seem promising, but in fact it is completely outweighed by the gains.

This thing requires a lot of saltpeter.

Rather than using this thing to make luxury goods like ice, it is better to use it to make gunpowder and make earthen flintlocks, matchlocks, explosive bags and other things.

Gunpowder was discovered very early in ancient times, and can be traced back to the alchemy of the Spring and Autumn Period.

But because there is no perfect ratio, the burning speed is very slow and the combustion is not complete enough.

For a long time, the so-called gunpowder was just a simple mixture of charcoal, sulfur and nitrate. It was very difficult to store and transport. It had many impurities and low power, so it was more suitable for use as fireworks.

But in fact, just having a ratio is not enough.

Purification is the key among the keys.

Sulfur purification, saltpeter purification.

By making the purity of these materials higher and following the optimal ratio, more powerful gunpowder can be produced.

This requires more information, such as new methods for preparing potassium nitrate (saltpeter), and how to purify sulfur and charcoal more conveniently.

Lu Yu shook his head, ignored this useless option, and continued to look at others.

Coarse salt purification method.

This method even mentions how to make coarse salt in large quantities.

Seawater drying method.

Seawater is introduced into the salt field for drying. When it is almost dry, the salt is changed to another pool. After crystallization, it becomes coarse salt.

Purification of coarse salt is also very simple. Mix coarse salt into water and then add lime milk made from limestone, and impurities will appear.

After repeated filtration and distillation, refined salt without bitter taste can be obtained.

This method is very simple and convenient, but it can produce quite exquisite salt, which is really a huge profit.

The only risk is that in ancient times, selling illegal salt was a serious crime.

However, the more business is included in the criminal law, the more profitable it is!
  Throughout the ages, people selling private salt have been banned repeatedly.

Even though there are many risks, this path can still be considered.

Lu Yu then looked at other information.

Seeing that Lu Yu was looking at it seriously, Bai Yuyao glanced at the food on the table, hesitated for a moment, but couldn't hold it back and secretly took several bites!
