Soar by day!

Taihuazi came to Qingniuguan for this matter.

"As long as you don't care about the merit being obtained by the old man, what does the old man care about!"

Xu Hao's proposal is of the greatest benefit to Taihuazi, he can share Xu Hao's merits, so naturally he will not have an opinion.

Taihuazi was already the world's top monk, and it was not difficult for him to create his own spells at all, after absorbing Xu Hao's knowledge of chemistry in the periodic table! After a month of retreat, he had improved the art of making food, so that the Monk could cast it.

After the spell was improved, he looked for Xu Hao and said: "The grain making technique has been transformed, and the monks of the Condensation Realm can learn it in a few days, but the Condensing Cultivators' divine thoughts are too poor, and the vitality they control is not much, and they can create a few taels of millet at most, this efficiency is too low, this is no longer something that can be solved by spells, and the old man can't do anything." ”

The space that can be controlled by the Divine Mind of the Contemplation Monk is only between 10 meters and hundreds of meters, taking the distance of 10 meters as an example, it can control about 300 cubic meters of space, and the carbon dioxide content in the air is only between 0.03% ~ 0.04%. Xu Hao remembers that the air quality of one cubic meter is about 1.29 kilograms, and the mass of carbon dioxide is a little higher than that of air, that is to say, the carbon dioxide in the cubic meter of air content is about half a gram, and the air of 300 cubic meters is only three taels of carbon dioxide.

Although the Condensing Cultivator is the cannon fodder at the lowest level of the cultivation realm, he is a golden collar to the people of Daqi, and he can earn 100 taels of silver a year, which is enough to buy 1,000 stones of food.

This Lianlian technique can only make a few or two taels of rice at a time, and the benefit is too low, basically it is impossible for monks to learn, and even if they learn, it is impossible to use this spell to save the people!

Xu Hao asked, "Taihuazi's predecessors have thought of a solution?" ”

Taihuazi pointed to the pressure vessel of the fertilizer factory not far away and said: "You can use the method of making chemical fertilizer to make food, compress that carbon dioxide into the container, such a container can make tens of thousands of stone of grain, but the only trouble is that nitrogen occupies most of the air, and carbon dioxide is too little, Lao Dao can't think of a way to compress them into the pressure vessel." ”

Xu Hao said: "That is to say, there is a way to make carbon dioxide industrially, and I will solve this problem!" ”

There are many ways to make CO2 industrially.

1. Calcination method: The industrial production of carbon dioxide is to produce carbon dioxide by calcining calcium carbonate at high temperature.

2. Fermentation gas recovery method: the carbon dioxide gas produced in the process of ethanol fermentation is produced, and carbon dioxide gas is prepared by washing, removing impurities and compressing with water.

For Xu Hao now, it is natural to find a limestone mine to calcine to produce carbon dioxide, which is the cheapest and most convenient!

However, Xu Hao found that the reason why the chemical fertilizer technique can be popularized, the concentrating monk can easily produce chemical fertilizer, because nearly eighty percent of the air in one cubic meter is nitrogen, which weighs almost two catties, and still takes the 10-meter divine perception distance of the contemplation monk as an example, 300 cubic meters of space can produce 600 catties of chemical fertilizer, which is equivalent to the weight of 10 stones in this world, and this is also the reason why the chemical fertilizer spell can be easily popularized. The production of chemical fertilizer can directly test the spells of the monks to achieve abundant food and clothing, without complex machine production lines, but the production of food must have an industrial production line to be produced in large quantities.

Xu Hao and Taihuazi Bing split into two ways, Xu Hao went to find a way to build a carbon dioxide production line (went to Hyundai to ask experts to help design it), while Taihuazi taught the outer disciples of Qingniuguan to learn the art of making grain!

Then the two sides converged and created an artificial food production line in Sanshui Village again!

The people and monks around couldn't believe it when they heard that this machine could make food, but Taihuazi performed several times out of thin air in front of everyone, (this is what the people think of!) In front of them, everyone naturally had to believe that this machine could really make food, and then it turned 180 degrees and became superstitious, after all, in the eyes of the people of this world, magic is omnipotent, and making a little food is nothing!

Then it caused a sensation among the people of Yuzhang County, and everyone sang and danced to celebrate this event.

After the war with the Sea Clan, everyone's life is not easy, although Yuzhang County here because Xu Hao opened a warehouse to release grain, stable food prices, but everyone also knows that Yuzhang County has become a troubled time, tens of millions of people have become starving, everyone is afraid that such a day will befall them, out of fear of the future, everyone is desperately hoarding food, and the world can not see the excitement of the past, after all, the survival rules of the troubled times are different from the prosperous times.

And now with this kind of spell that can make food out of thin air, everyone naturally doesn't have to worry that they will starve to death, the victims of Daqi can be resettled, and the prosperous era they are looking forward to will come back again, everyone is naturally happy, and for a while, the people of Yuzhang County have returned to the lively scene of the past!

On the first day of the opening of the grain production line, everyone rushed to Sanshui Village to see how the grain was made from the organs!

"Hongyuan, can this machine really make food?" Li Defeng was skeptical. His knowledge is higher than that of ordinary people, even if he hears the people say that Taihuazi can create things out of thin air, but he still doesn't believe that if machines can make food, what will happen to the people who farm in the future?

Hongyuan showed his grain-making skills to Li Defeng.

Li Defeng looked at the few taels of rice in Hongyuan's hand in surprise, maybe he didn't believe it, he even tried it before saying: "The taste is really bad, it's worse than the rice in the southern Xinjiang country, but it's really food!" ”

Hongyuan said: "This is called the grain making technique, it is a spell created by Xu Hao, it is said that it is made with a kind of vitality called carbon dioxide that is ubiquitous in the world and is the same as chemical fertilizer, but this kind of vitality that can make food is too little, and you can only use the mechanism to collect this gas, and then let the monk cast a spell to make food!" ”

At this time, the production line is opened, and countless carbon dioxide are compressed into a pressure vessel by the compressor, and then the carbon dioxide and other gases are synthesized into artificial starch under the spell of the monk, and when these starches come out, they become grains of rice!

"Wow!" Everyone exclaimed when they saw the rice coming out, and it was the first time that rice could be made without farming!

And Chu Chengjun, who came here early, was the first to come to the machine and eat the rice he made.

It's true! Chu Chengjun finally saw the hope of Daqi to stop the decline!
