I studied abroad in modern times

In a nursing home.

As night fell, the chef had also left with his team. Zheng Fa and the four of them moved a few more deck chairs and laid them side by side in the courtyard.

The ecological environment here is very good.

The weather is sunny today, the stars are twinkling in the night sky, and the grass and trees are sending fragrance.

The breeze blew slowly on the mountainside, and the four of them talked endlessly but happily.

"Their condition is that they come to purchase every day, and I will send you the price." Old Man Bai turned his head and said to Zheng Fa.

Zheng Fa nodded. He also looked at the other party's bid.

He also knows some prices - on weekends during his three years in high school, he would always go to the vegetable market and buy some roast chicken or something.

But the other party's offer was a bit generous.

The same tomatoes may cost a few yuan per pound in the vegetable market, but the price quoted in this quotation is several hundred times higher, more than a hundred times higher.

This is still a relatively low increase.

For some vegetables, the price increase is even more extreme.

Seeing that Zheng Fa was silent, Old Man Bai seemed to think that he was too low, and explained: "This should be the most sincere offer from the other party."

"Huh? Are you so sincere from the beginning?"

This is a bit contrary to the way of doing business...

"Not yet..." Old Man Bai pursed his lips towards Zheng Fa and pointed at Tang Lingwu.

Tang Lingwu smiled sheepishly: "I asked my dad about the restaurant's turnover and ingredient costs, and also checked the other party's supply channels. After calculation, they should not have lowered the price."

"This...should be a trade secret, right?"

Zheng Fa was stunned.

This almost took off the other person's underwear.

"Many times, the word "confidential"..." Old Man Bai sighed with emotion when he heard this: "It's just another expression of your lack of qualifications."

Zheng Fa was speechless when he heard this, and then Old Man Bai continued: "But they still have demands."

"What?"

"Exclusive supply, and they even want to put demands on us - that is, we will grow whatever they want. They say we can increase the price."

This is not surprising. For a restaurant of this level, the word exclusive may be more important than delicious food.

As for the lower demand, it is natural to want more initiative.

"A lot of extra money." Old Man Bai clicked his tongue: "The extra money in one week may be more than what I made in the previous year."

That's a bit much.

Although there are not many fields where you can make money by doing mathematics, as a professor at Beijing University, Old Man Bai can still earn millions in salary plus sideline income per year.

Zheng Fa thought for a while and said, "If we don't agree, how much will our monthly income be?"

Old Man Bai glanced at him and said: "Ling Wu has calculated that their prices are high, but the demand is actually not large - about 600,000 a Friday."

Zheng Fa then understood why Old Man Bai was a little moved.

If you agree to the other party's conditions, the income of the nursing home will be at least twice as much.

"Teacher Bai, I have mentioned the three principles of nursing homes before." Zheng Fa was silent for a while and said: "This business... is just a by-product of our research - our energy should not be affected too much by it."

Old Man Bai smacked his lips and already understood Zheng Fa's thoughts. He just sighed: "At my age, I am confused when I see this money...but you..."

Tang Lingwu on the side nodded slightly, smiling, and agreed with Zheng Fa's expression.

"You girl, you have this expression no matter what Zheng Fa says, this business is obviously your idea..." Old Man Bai muttered, as if he couldn't stand it.

"It was my idea, but... Zheng Fa is Zheng Fa."

Zheng Fa was stunned and looked at Tang Lingwu, wondering why she said that.

Tang Lingwu lay on the rocking chair, looked at the starry sky, and said softly: "He knows what he wants. He always walks in the same direction. He just wants to see what it is like to cultivate immortality. Isn't that why we got together?"

Old Man Bai was stunned and suddenly laughed.

Teacher Tian on the side patted him and said with a smile: "I think you can't see clearly as well as two other children."

…

The matter was finished in a few words, but the next thing made several people think a little.

"Thunder and lightning? Spiritual plant?" Old Man Bai frowned: "To put it simply...this thing is too rough."

Zheng Fa understood what Old Man Bai meant.

This is simply an idea.

"Changes in the magnetic field can trigger and promote the production of spiritual plants. What kind of changes in the magnetic field? Big or small? Big and small changes? In which direction and how long?" Old Man Bai muttered: "There are so many things. We don’t know where to start.”

"I do know a kind of thunder method. According to legend, it can promote the growth of grass and trees." Zheng Fa suddenly said: "It should be said that there are three imperfect thunder methods, the heavenly tribulation thunder, the cloud and rain thunder, and this - I Call it Lingmu Lei.”

At this point, Zheng Fa was helpless.

The three thunder methods in the Monument World are so crude. The names are all chosen from scratch.

For example, the Heavenly Tribulation Thunder and Yunyu Thunder were taken by Yan Wushuang and the others.

But he didn’t take the Lingmu Thunder—mainly because he couldn’t see any hope of mastering it, so out of sight was out of mind!

"Three types of lightning techniques?" Tang Lingwu on the side asked: "What are the differences between the three types?"

"The Heavenly Tribulation Thunder pursues power control."

"Yunyulei is the pursuit of controlling rainfall."

"And Lingmu Lei controls the growth of vegetation."

Zheng Fa slowly concluded.

"This sounds more difficult than the other." Old Man Bai said: "We can think of power as current intensity or voltage intensity, and the other two are different."

"Yes." Zheng Fa also had his own thoughts on this matter: "Clouds, rain and thunder, if we consider the process of rainfall, it may be to change the polarity of water molecules, use electromagnetic fields to aggregate them into raindrops, or to allow the raindrops to dissipate and vaporize—— This is relatively simple large-scale electromagnetic field control."

"And Lingmulei is even more difficult to understand, even if Teacher Tian's conjecture that the magnetic field changes plants is true." Zheng Fa wanted to sigh even more when he talked about this: "The changes of water molecules or raindrops in the electromagnetic field are clear. "But how plants change is unclear, and the required magnetic field changes may be more complex and microscopic."

The faces of Old Man Bai and others were a little serious.

Obviously the difficulty can be seen.

"So I said these are three thunder methods that are not perfect at all." Zheng Fa explained: "It can be said that they are three brand-new topics. Of course they are a bit difficult, but the experiment on the tribulation thunder is quite simple."

Zheng Fa did not mean to despise these three thunder methods. It can be said that there are many monks from the Xuanwei world who are good at thunder methods gathered in the monument.

Facing these three thunder methods, they were also clueless.

Without the modern world, Zheng Fa would not have the confidence to have a better understanding of Lei Fa than these people...

"Don't be afraid of difficulties." Teacher Tian smiled at this time: "If you have a direction, you can always get there..."

"That's really a good thing to say." Old Man Bai smacked his lips: "Why do I suddenly feel that cultivating immortals is a perfect match for scientific research..."

Zheng Fa also wanted to sigh.

He had already considered this matter...

If there is a scientific civilization in the Xuanwei world, hundreds of thousands of years can be used to explore the world.

I'm afraid it's no longer what it is now.

But on the other hand, scientific civilization is not inevitable...

…

A few days later, a long metal pole was placed in front of Zheng Fa. The metal pole was connected to several sensors - current sensor, voltage sensor and infrared sensor. The sensors were connected to optical fibers, and the optical fibers were connected to Tang Lingwu's computer in the room.

A high-speed camera was placed dozens of meters away from him.

Zheng Fa admitted that Yan Wushuang and others may be more savvy than him in thunder methods...

But he has never been in the field of understanding...

Isn’t it fun to experiment?

For safety, Old Man Bai and the three of them were watching him in the house.

This was the first experiment conducted by several people on the Heavenly Tribulation Thunder.

To prevent the aura from interfering with electromagnetic fields and signals, these items are placed outside the aura's range.

The spiritual power in Zheng Fa's body surged out of his body, and under the control of his divine consciousness, it operated according to the patterns of the Heavenly Tribulation Thunder on the Book of Gods.

It was not the first time he used magic, but he did use it very rarely.

In his view, the magic and talismans of the Xuanwei world are two things of the same coin.

For example, now, his consciousness controls his spiritual power, and the way it operates in the void is very similar to runes - but the difference from runes is that he is controlling his spiritual power to "capture" things in the void. Talisman diagram.

This method is very inefficient. In fact, the power of the spell is more determined by the intensity of the spiritual power used.

The talisman method is to gather the talismans in the air onto the talisman paper, and the spiritual power injected by the monks becomes a small head.

There are other differences between the two - for example, the spell takes too long to move forward, while the magic talisman is extremely fast.

Therefore, spells were gradually replaced by talismans.

Senior Sister Zhang's "Yuan Fu Foundation Building Method" goes a step further, is faster, and does not require talisman paper and spiritual ink.

Now this Heavenly Tribulation Thunder is not even a spell.

Zheng Fa can feel that many of the trajectories of his spiritual power in the air are useless, and some seem to absorb the runes in the air, but he doesn't know what they do.

The difference between the Heavenly Tribulation Thunder and the thunder method in Xuanwei Realm is that it is extremely powerful, even too powerful to be measured.

It is not that Zheng Fa has never used thunder talismans, but they rarely reach the power of the Heavenly Tribulation.

For many cultivators in the Xuanwei Realm, it is easier to say whether they are weak or powerful, and everyone can understand it.

But it is difficult to accurately measure the difference between extremely powerful and extremely powerful.

When the thunder went down, everyone turned into ashes, and it was hard to tell whether they were familiar...

Even if it is felt, it is difficult to measure accurately.

But with the help of modern instruments, Zheng Fa was able to - to a certain extent, the progress of modern science is based on the progress of observation methods.

…

As Zheng Fa's spiritual power circulated, suddenly, a bolt of lightning appeared in the air and landed on the metal pole.

"How are people?"

Before Zheng Fa said anything, Old Man Bai and others in the house rushed out and asked.

"It's okay." Zheng Fa shook his head slightly and said to Old Man Bai: "I will draw the pattern of my spiritual power just now. Please help me take a look."

"OK."

that's all.

Lightning bolts struck the metal pole one after another.

A trace of the movement of spiritual energy appeared in Old Man Bai's notebook.

The relevant data such as current, voltage, temperature and even the length and width of the lightning were recorded on Tang Lingwu's computer.

They didn't stop the experiment until Zheng Fa's spiritual power was exhausted to a certain extent.
