Unfortunately, before the cards are revealed, no one thinks that they will lose everything. Even the smartest people always want to take a gamble.

Moreover, those who can enter the core have their own pride. Shangguan Yi's age and experience make it impossible for him to surrender easily, so Wang Zheng's suggestion is not even within his consideration.

"Thank you for your concern, Chief Steward. I will go back and think about it before giving you a reply, okay?"

Looking at Shangguan Yi, who appeared respectful but had a disappointed look in his eyes, Wang Zheng smiled indifferently and did not continue to persuade him. Good advice is often difficult for people to accept.

"I haven't bothered much. I can't do anything about the situation. As for what to choose, it's up to you, Lord Shangguan."

"I'll take my leave."

"Sir, please go slowly."

Looking at the melting snow, Wang Zheng turned and walked into the greenhouse. He took a brush and gently brushed the flowers next to a row of cucumber racks.

Chen He nodded in agreement and said, “Well, in the past, Confucianists measured wealth by land, and always thought that the wealth in the world was fixed, but our ancestors measured wealth by productivity.

Zhang Xin looked at Liu Hui speechlessly and said with a smile: "Do you think these fruits and beans are produced by themselves?"

This is a job that requires a lot of patience. Fortunately, Wang Zheng has a lot of patience. After all, he was the one who managed to be trapped in Yuzhou for six or seven years. If he didn't have enough patience, he would have rebelled long ago.

The voice came from outside the greenhouse. It was said by Chen Yu who had just stepped over the threshold.

Liu Hui and Wang Min looked at Xiao Yuehua with questioning eyes.

Chen He shook his head and explained, "What Zhang Xin meant is that there is a trick here. Ordinary people simply cannot make fruits and vegetables bear fruit in a greenhouse. This must be some secret method our ancestors used to make these fruits and vegetables bear fruit in a greenhouse."

Today is February 30th. After Xiao Yuehua got home from school, she excitedly took her friends to the greenhouse of Chen Yu's house. Looking at the fingertip-sized cucumbers, eggplants, and small sprouts of various beans, she couldn't help but exclaimed.

Although this job is boring, it is still quite fulfilling to watch the fruits and vegetables grow. This is the joy of harvest.

Xiao Yuehua waved her hand nonchalantly and replied, "It's okay. My father has plenty of secrets like this. He never thought of keeping them secret back in Yuzhou. My father once said that as long as it is not a destructive secret, it does not need to be kept secret.

Xiao Yuehua nodded and smiled, "Daddy did say there is a way to make these fruits grow in the greenhouse, so he persuaded me to plant these things. As for the specific method, I didn't ask, but now that they are blooming in large quantities, we must do something. Daddy will naturally teach us tomorrow."

Wang Min said with some doubt: "In the past, even the people in Chang'an could hardly earn one guan of money a month, but now the people in ordinary counties can earn three or two guan of money a month as long as they have something to do.

"Class teacher."

After all, she is his favorite youngest daughter. Since Xiao Yuehua is willing to do something serious, as a father he naturally has to support her.

Zhang Xin hesitated for a moment and said, "It would be bad if we knew this secret method, right?"

Looking at Shangguan Yi's desolate back, Wang Zheng smiled and sighed, then let the matter go. What was there to worry about with an inevitable ending?

Now, when Wang Zheng has nothing to do every day, he wanders around the various greenhouses in the Fifth Courtyard, helping Xiao Yuehua and the others pollinate various fruits and vegetables.

The more these methods that can improve productivity are spread, the better. After all, wealth comes from creation. After everyone knows the methods, the Tang Dynasty will become richer. If the whole world is rich, why worry about not having a way to make money? If the whole world is poor, no matter how powerful the skills are, it is impossible to make much wealth. It was because of my father's words that Your Majesty spread many secret methods of Yuzhou. "

Now Zhang Xin was completely speechless, Xiao Yuehua just smiled and said nothing, and Wang Min looked confused.

Chen Yu shook his head and said with a smile: "This is a huge subject, I don't know the details, but your majesty has a group of specialized people doing the calculations.

Greenhouses have spread widely in the north. Now that we have winter vegetables, winter fruits should also come into being.

Then Wang Min asked: "How should wealth be measured?"

Zhang Xin nodded and sighed, "Only a saint like our Grandmaster, who has the world in his heart, can see things so clearly. The fact that the Tang Dynasty has become increasingly wealthy over the years is indeed largely due to the secret methods of our Yuzhou family.

Liu Hui was stunned and asked, "Did you make them bear fruit?"

Liu Hui said in confusion: "I never thought that the fruits and beans in the greenhouse can really bear fruit. Why didn't those guys who used to run the greenhouse sell these fruits and beans?"

"Class teacher."

Wealth has indeed increased a lot, but according to our productivity, it seems that there shouldn't be so much wealth? This seems a bit strange?"

"That's because wealth is not measured in a simple way of adding or subtracting."

Apart from other things, the use of various secret methods of water power alone has increased the productivity of the Tang Dynasty by several percent. The same number of people can do more things, so production will naturally increase, and with more surpluses every year, the world will naturally become richer and richer. "

Several little girls came out of the greenhouse and greeted each other.

But I can explain it to you in a simple way. For example, we used to exchange silk, tea, porcelain and other things with the places west of the Western Regions for glass, wine and other things.

Generally speaking, we still make money every year, but not much. However, our own glass, wine and other products are now better than those in the Western Regions, and all the good products we had in the past, such as porcelain, are sold to the Western Regions.

In this way, the people in the Western Regions will have to exchange good things with us, such as gold, silver, and iron. In this way, with only money coming in and not going out, our Tang Dynasty will naturally become richer and richer.

In addition, our fleets continue to gain wealth overseas. As money increases, houses, antiques and other things become more and more valuable, further pushing up wealth, and naturally wealth increases."

"It sounds a bit confusing, but it seems pretty impressive."
