Could he go?
Was there a need to ask?
He didn't know the situation before, so it was reasonable for Fang Xuanling to invite him. Now that Zhang Feng had made everything clear, whoever dared to intervene in this matter, what would that be?
That was simply courting death!
And it was a capital offense that no one could escape.
After all, who would dare to intervene in something that even the Emperor didn't dare to mess around with?
What was that? It was the people's granary!
At this moment, Fang Xuanling didn't say anything.
He made a fist salute and was ready to leave. He also understood why Zhang Feng went down the mountain at this critical moment.
And he didn't even go home.
He wanted to find a way to solve this problem!
However, Zhang Feng hurriedly pulled Fang Xuanling back. He winked and said, "Don't go, Old Fang. I said that I'll take you to have fun later. Why are you in such a hurry?"
Seeing Zhang Feng's expression, Fang Xuanling felt a chill.
"I really don't suit that kind of place. After all, that place really doesn't suit me!"
Zhang Feng glanced at Fang Xuanling's thin body and said, "What are you thinking about?"
"Let's go. I'll take you to a place to relax. I didn't say that I'll take you to drink wine!"
Fang Xuanling: "…"
Half an hour later, Zhang Feng and Fang Xuanling arrived at the Shili Slope outside Chang 'an City.
After the fire caused by the locust plague, the woods here were more lush and green. After passing through the woods, they came to the field area located at the Shili Slope.
Guanzhong was mostly a plain, so at this time, the Shili Slope was an endless stretch of yellow land. At this time, there were shouts everywhere. Cattle and people galloped in the fields, and the yellow and black land that was still emitting black smoke was flying under the plow.
Zhang Feng finally knew why there was so much haze in Xi 'an.
They didn't know if it was because of the large area of burning straw.
Zhang Feng pointed at the people who were burning straws further away, or who were throwing leaves from trees onto the burning land. He asked in shock, "Old Fang, what are these people doing? Could it be that your farming is like this now? "
Fang Xuanling didn't know what Zhang Feng meant. He asked, "Is there any other way?"
"Alas!"
Zhang Feng sighed painfully.
He finally understood why the output of the people in this era was low.
Because of this, the alkalinity of the soil increased year by year. It would be ridiculous if they could have a good harvest.
"I say, Old Fang, this is where you guys are wrong. If this really works, I, Zhang Feng, will write it backwards tomorrow!"
Fang Xuanling was a little confused.
"Since ancient times, it has always been like this. First, we use fire ash, then we add some farm manure and stuff like that. Isn't it all good?"
"Why can't it work when it comes to you?"
Zhang Feng shook his head, "It's not that it doesn't work … Forget it, you won't understand even if I tell you. Come, come, come, Old Fang."
Fang Xuanling squatted down suspiciously. Zhang Feng grabbed a handful of soil and handed it to Fang Xuanling, saying, "Try it."
As he spoke, Zhang Feng dipped a bit of soil into his mouth and said, "Try it."
Fang Xuanling was very conflicted, but seeing that Zhang Feng had eaten it, what else could he do?
He copied Zhang Feng and picked up a piece of soil from the ground and threw it into his mouth without looking. Instantly, a sour taste and a rotten smell made Fang Xuanling almost vomit.
Seeing this, Zhang Feng spat out the soil in his mouth and rinsed his mouth with the wine in the wine bag he carried with him. Then, he handed the wine bottle to Fang Xuanling and asked, "How is it? Now you know the taste, right? "
Zhang Feng ignored Fang Xuanling and went back into the forest. He searched for a piece of dry white soil under the roots and handed it to Fang Xuanling again.
"Try this soil."
Fang Xuanling didn't speak at this time. He took the soil from Zhang Feng's hand and threw it into his mouth. Instantly, Fang Xuanling's expression froze.
It was the same kind of mud, but the smell was completely different. The mud here had a fishy smell, and there was a bitter smell of dried leaves, but it didn't have the salty and astringent taste.
This time, he couldn't help but be a little shocked.
Zhang Feng smiled and said, "You noticed it too? Look, the distance from here to the field is less than five feet, but why is the soil like this? "
Fang Xuanling asked in horror, "Is it because of the salty alkalinity?"
"Yes!"
"But my phosphate fertilizer can neutralize the salty alkalinity in the soil. Think about it, if I soak you in a vat of vinegar all day, what will happen to you after a long time?"
"Everyone will get sick, not to mention the farmers."
"Only by neutralizing the salty alkalinity in the soil and letting the nutrients completely volatilize can the farmers grow better. Thus, the grain output can increase dramatically!"
Although Fang Xuanling didn't understand the principles behind it, he gradually understood.
However, this incident allowed him to gradually understand something. For example, the fine salt, the white paper, and the braised meat were all similar things. However, after passing through Zhang Feng's hands, they had undergone an earth-shattering change in an instant.
These things were originally very common and common items. But …
Thinking of this, Fang Xuanling had a bold idea.
Could it be that this kid could turn stone into gold?
