Jiang Ziya forcibly suppressed the joy in his heart, no matter whether what the Northern Underworld Daoist in front of him said was true or not, he was the first to assist himself in presiding over the matter of sealing the gods, and it was related to Yun Zhongzi, so he should not be neglected.

"Dare to ask the Northern Underworld Daoist, can you tell me more specifically!"

If it is really as the Northern Underworld Dao people themselves say, for the human race, the role is almost no less than that of a Great Luo Jin Immortal.

There is no shortage of great supernatural powers under the sect, but for those who are proficient in human affairs, except for Jiang Ziya himself, he can no longer find any disciples, so it makes the people of the Northern Underworld Dao more and more rare and valuable.

"Haha, don't hide it from Brother Ziyadao, poor Dao knows how to make farming tools, which can increase grain production, and can also smelt metals, and can make weapons. The Northern Underworld Daoist said with a chuckle.

During the Shang Dynasty, the common people of the human race already knew how to plant five grains, that is, rice, millet, millet, wheat, and soybean, but the grain produced per mu was very scarce, and sometimes it was difficult to eat and dress after being busy for a year.

In the event of a bad year, there will be only 100 catties of grain per acre of land, and even if the wind and rain are smooth, it will only be 1200 catties of grain at most.

Moreover, there are no high-yielding crops such as corn and sweet potatoes.

Unlike the previous life of the Northern Underworld, the yield of corn per mu is generally 1200~1400 catties, and the yield of wheat is 800~900 catties, and the yield per mu is scary.

Farming implements!

"Oh, I don't know what kind of farming tools you know!"

Jiang Ziya's eyes immediately flashed, and if he wanted the wind and rain to be smooth, he could cast a magic spell.

But farming tools are a thing, and I'm afraid even the saints are helpless.

The Northern Underworld Daoist thought for a moment and said a kind of waterwheel in the historical records of his previous life.

The waterwheel is an ancient tool for lifting water for irrigation.

The waterwheel, also known as the sky crane, slowly rotates the spokes by the inertia of the movement of the water potential, filling the bucket with river water and lifting it up step by step.

At the top, the bucket slopes naturally, pumping water into the aqueduct and into the farmland in need of irrigation.

In the previous life, there were waterwheels in the Eastern Han Dynasty.

As for the desolate world, is there a waterwheel?

The people of the Northern Underworld Dao were not sure, at least he and Yun Zhongzi came all the way to Chaoge, and they didn't see the waterwheel.

Waterwheel!

No magic spells required!

It doesn't take any human effort!

As long as you choose a riverside and build a waterwheel, you can continuously send river water into the fields without human care or animals, which can be described as saving time and effort.

For a while, Jiang Ziya couldn't wait to build the waterwheel immediately, and try to see if it was really as magical as the Northern Underworld Dao people said.

"Daoyou is really knowledgeable, but Ziya is far inferior. ”

"However, Ziya still has one more thing to worry about Daoyou, so when the materials are ready early tomorrow morning, I will also ask Daoyou to build a waterwheel. Jiang Ziya showed a hint of shame.

It is really a matter of great importance to the waterwheel, and if he does not see the real thing for a day, Jiang Ziya will have trouble sleeping.

Regardless of the period of the gods, or the ancient times in the previous life, farming is better than any major event in the court.

During the Han Dynasty in the previous life, even the emperor and concubines had to go to the fields to farm, and even Emperor Wu of the Han Dynasty always paid attention to the face of the royal family and never backed down in case of trouble.

Only when encountering the incident of Nongsang will they choose to back down regardless of their face.

In this regard, the people of the Northern Underworld Dao are naturally very clear.

"It's not difficult, as long as there is enough timber and craftsmen, the watermill can be built early tomorrow morning. ”

If it was in his previous life, he naturally didn't dare to say it, and he could build a waterwheel in one day.

But now, he is a qi practitioner, and the drawings of the waterwheel seem to be engraved in his mind, not to mention a day, but half a day to build the waterwheel.

"Good, good, good. ”

"With the words of a Taoist friend, Ziya is relieved for the most part. ”

"Let's go have a glass of water and wine and celebrate. ”

After speaking, Jiang Ziya pulled the Northern Underworld Daoist to stand up and walked towards Song Yi's house.

Ignoring the falling fish baskets and fishing rods.

Not long after, the two walked into Song Yi's house together, Jiang Ziya laughed loudly and shouted: "Brother Xian quickly prepare wine and food, Ziya is going to entertain a distinguished guest today." ”

Hearing this, instead of showing a trace of dissatisfaction, Song Yiren immediately ordered to go down and let people prepare more wine and food, and he got up and walked towards Jiang Ziya.

"Come to think of it, this is the distinguished guest that Brother Ziya said!"

As soon as Song Yiren saw the face of the Northern Underworld Daoist, he was immediately shocked, he was so extraordinary that he was really a distinguished guest.

"That's right, it's the distinguished guest that the poor Dao said, you can't be stingy for a while. Jiang Ziya and Song Yiren were not polite at all.

"The poor Dao Lishan Qi Practitioner Northern Underworld Dao is a person who has seen the head of the Song family. The Northern Underworld Daoist bowed slightly and said politely.

"The head of the Northern Underworld Dao doesn't need to be polite, please come in for a while. ”

Song Yiren invited the Northern Underworld Daoist into the house, and glared at Jiang Ziya at the same time.

In the past few days, he has been pulling strings for Jiang Ziya's media everywhere, wanting to choose a good family.

But Jiang Ziya was good, he went out early and returned late every day, and hid out directly, and there was no one to see.

In this regard, Jiang Ziya didn't see it, and walked inside by himself.

After a while, a family brought up food, wine and food, a large table full of fish and meat, and the style was very rich.

The people of the Shang Dynasty were not wealthy, and sometimes they couldn't even eat green vegetables, and the meat could only be tasted during the New Year's holidays.

It shows that Song Yiren is very generous, and there is no shortage of money and food at home.

However, looking at the wine and food on the table, the people of the Northern Underworld Dao were not interested at all.

The green vegetables look good, but they are too greasy, with a smell, as if they are cooked with mutton fat, and the meat is only fish and mutton.

As for pork, no.

At least during the Shang Dynasty, almost no one in the human race ate pork, not even a pig breeder.

On the contrary, there are a lot of cattle, but cattle are an important labor force in the human family, even more precious than human life, even high-ranking officials and nobles can't afford to eat it, and at the same time dare not eat it.

Therefore, the only meat is fish, sheep, chickens, ducks, hares, etc., some common beasts.

The wine is also muddy, with a little bit of alcohol mixed with bitterness, somewhat like dark beer in the previous life, but it is not delicious.

The people of the Northern Underworld only tasted it a little, and then stayed away.

"Dao Chief, but I don't think the food and wine are to taste!"

Seeing that the people of the Northern Underworld Dao barely touched a drop of water, Song Yiren couldn't help but ask a little strangely.

"It's not that the wine and food of the Song family are not in line with the taste, but that the poor road is dedicated to pure cultivation, and he has long stopped eating human grains. The Northern Underworld Daoist explained.

Qi practitioners can eat and drink dew, swallow and breathe the purple gas of the morning glow, and they have long stopped eating cereals.

Of course, if it was some spiritual objects or immortal spirit drinks, he would not be able to taste one or two of them.

Although the people of the Northern Underworld Dao have not yet set foot in the Immortal Dao, there is still a long way to go before they can practice the Void Combination Dao realm.

But after all, he is extraordinary, and he is not a qi practitioner in the human race.

Besides, at this time, there is no appetite, and I can't have the slightest interest in the wine and food in front of me.
