Can I go?

You know what?

I didn't know the situation before. If Fang Xuanling invited me, it would be too much. Now Zhang Feng has made everything very clear. If anyone dares to intervene in this matter, what is it?

That's death!

And no one is guilty of Farah's death.

After all, the emperor likes things that he doesn't dare to mess with. Who dares to step in?

What's that? It's the granary of the people!

At this time, Fang Xuanling said nothing.

Baobaoquan was ready to leave. He also understood why Zhang Feng went down the mountain at this critical moment.

And I don't even go home.

This is to find a solution to this thing!

But Zhang Feng hurriedly grabbed Fang Xuanling and said, "don't go, old Fang, I told you to take you to be natural and unrestrained. What's the hurry?"

Seeing Zhang Feng's look now, Fang Xuanling was cold.

"The little old man is really not suitable for any kind of place. After all, that place is really not suitable for aging!"

Zhang Feng glanced at Fang Xuanling's thin body and said, "what do you think?"

"Let's take you to a place to relax, but I didn't say to take you to drink flower wine!"

Fang Xuanling: "

Half an hour later, Zhang Feng and Fang Xuanling came to Shilipo outside Chang'an city.

After the last locust fire, the trees here are more lush. Through the woods, we come to the Grange area located on Shilipo.

Guanzhong is mostly plain landform, so when you look at the ten mile slope at this time, there is a vast expanse of loess land. At this time, there are cries everywhere. A yellow cow and the people are galloping in the field, while the yellow and scorched land still emitting a trace of black smoke is dancing under the plowshares.

Zhang Feng finally knows why there are so many smogs in Xi'an.

I don't know if it's caused by burning straw in a large area.

Zhang Feng pointed to the people who were burning straw in the distance, or dumping fallen leaves on the burning land with baskets of tree leaves in their arms from the woods, and asked in great shock, "old house, what are these people doing? Is this what you are doing now?"

Fang Xuanling didn't know what Zhang Feng meant and asked, "is there any other way?"

"Alas!"

Zhang Feng sighed bitterly.

He finally knew why the output was low.

Because of this, the alkalinity of the soil increases year by year. If it can have a good harvest, it's bullshit.

"I said Lao Fang, this is your mistake. In this way, if I can be a dealer, I Zhang Feng will write backwards tomorrow!"

Fang Xuanling is a little confused.

"It's been planted like this for thousands of years. First it uses fire ash, and then it gets some farm manure and other things. Isn't it all good?"

"Why can't I come to you?"

Zhang Feng shook his head: "no, I can't... forget it. I told you you you don't understand. Come on, come on, you come to the old house."

Fang Xuanling squatted down suspiciously. Zhang Feng grabbed a handful of soil and handed it to Fang Xuanling. "Taste it."

While talking, Zhang Feng threw a little soil into his mouth and said, "try it."

Fang Xuanling is very tangled, but seeing that Zhang Feng has eaten, what can he do?

Learning from Zhang Feng's appearance, he picked up a piece from the ground without looking at it. He threw it into his mouth. In an instant, a sour smell and a rotten smell made Fang Xuanling almost spit it out.

Seeing this, Zhang Feng spit out the sediment in his mouth and rinsed his mouth with the wine from the wine bag he carried with him. Then he handed the wine pot to Fang Xuanling and asked, "how about it? Now you know the taste?"

Zhang Feng ignored Fang Xuanling, turned back into the forest, searched for a piece of dry white soil from the root of the tree, and handed it to Fang Xuanling again.

"You're tasting the soil."

Fang Xuanling didn't speak at this time. She picked up the soil from Zhang Feng and threw it into her mouth. In an instant, the look on Fang Xuanling's face solidified.

It's the same mud, but the smell is very different. The smell of the soil here is a little fishy. There is a bitter smell of dead tree leaves, but there is no salty and astringent taste.

Now, he couldn't help being shocked.

Zhang Feng smiled and said, "you also found it? Look, it's less than five feet away from the field, but why is the soil like this?"

Fang Xuanling asked in horror, "is it because of this salinity?"

"Yes!"

"But my phosphate fertilizer can neutralize the saline and alkaline components in the soil. Think about it. What will happen if you soak someone in a vinegar jar one day?"

"Everyone gets sick, not to mention the dealer?"

"Only by neutralizing the acidity and alkalinity in the soil and allowing the nutrients to volatilize completely, can the farmers grow better, so that the output of grain can increase sharply!"

Although Fang Xuanling doesn't understand the way.

However, this thing made him gradually understand something, such as the fine salt, white paper and marinated meat. However, after passing through Zhang Feng's hand, earth shaking changes took place in an instant.

The original things of these things are very common, but

On this thought, Fang Xuanling had a bold idea.

Can this boy turn stone into gold?
