ps: Reading the book review, it seems that many book friends think that biogas is a bug, in fact, dig a deep pond underground, dilute the Xiang with a little water, add some river bottom, swamp silt or something into it, and then close the pool cover, leaving only one pipe, a week to a month or so can produce gas, there is no need for a valve system or something like a book friend said.

The soil naturally has the effect of thermal insulation, as long as you pay attention to the closure, the temperature of the outdoor and the pool can be very different, if the temperature is still not up to standard, you can pass another pipe, to pull the bellows to pour hot gas into the pool, the pipe can be replaced by bamboo, as long as the gas is deflated on time, it will not burst. Therefore, it is not too advanced to talk about anything, and it should not be confused with the biogas production system under the management of modern technology, which is a modern process, and it can be done with the same method as soil.

———— the following text————

When the time enters Layue, on the battlefield of the West Road, whether it is the Wei army or the Chu army, it seems that they have completely stopped cooking, and they can hardly see any movement anymore.

Even in the snowfields around Juyang County and Bingcheng, there was almost no shadow of the scouts of the two armies, and there was a white expanse everywhere.

Although Zhao Hongrun was quite depressed about the ice and snow, after all, it made him have to postpone the process of attacking Juyang County, but aside from this factor, he actually liked such spectacular snow scenes very much.

No, on the first day of December, on a sunny day, Zhao Hongrun once again climbed an ice-made watchtower in the ice city and looked at the seemingly endless snow scene outside the ice city.

During this period, Zhao Hongrun and the guards encountered Yan Mo and Nanmenyang, who were patrolling.

"Your Highness seems to be very fond of snow?"

Nanmen Yang asked curiously, because since he had temporarily suspended the attack on Juyang County, he had noticed more than once that His Royal Highness King Su had ascended to the top and looked out at the snowfields outside the ice city.

"Ah, this king has rarely seen such a magnificent snowy scene before."

Zhao Hongrun replied casually, after all, in his memory, when he was born, Jiangdong was almost impossible to see such a spectacular snow scene. When I was a child, there were thousands of tons of snow every winter, sometimes only half a palm's thick, sometimes no snow at all, or snow at night, and when I woke up in the morning, the snow had already melted, and I couldn't even build a snowman.

It is like the snow on the snowfield outside the city at this moment, which is enough to reach the big crotch of an adult man, causing the entire snowfield to be white and boundless, how spectacular it is.

"Is there very little snow in Dawei in winter?" Nanmen Yang looked at Zong Wei Chang Wei Jiao in confusion, but saw that the latter also shrugged his shoulders in confusion.

It's no wonder, after all, sometimes the talents of His Royal Highness are incomprehensible even to Wei Jiao, Lu Mu and other sect guards.

Of course, I believe that at this moment, I am afraid that only Zhao Hongrun is the only one who really has the heart to appreciate this snow scene, after all, for the people of this era, especially the Chu people, snow is not a beautiful appreciation, but a disaster, a great disaster.

For example, Yan Mo, at this moment, when he looked at the snow field outside the ice city, he was slightly distracted.

It's no wonder, after all, Yan Mo's younger brothers and sisters died of hunger and cold in such a cold environment.

After this snowfall, I don't know how many civilians in Chuxi and Chudong died of hunger and cold......

Yan Mo sighed faintly.

And the rest of the generals didn't know why, looking at the snow outside the city one by one, they were quite a little unwilling.

It may be that they thought of their families, whether they were in the State of Wei or still in the State of Chu.

This is not surprising, after all, for the generals in the army, either they are not idle, and they tense their nerves day and night, otherwise once they are idle, they will inevitably miss their families, which will have a certain impact on morale, which is inevitable.

"Your Highness?"

With a soft shout, Wu Ji of the Shangshui Army also came here with a few personal soldiers and hugged his fists towards Zhao Hongrun - he had just finished inspecting the situation of the soldiers under his command.

"What is the condition of the soldiers?" Glancing back at Wu Ji, Zhao Hongrun asked with a smile.

"Heating is not a problem." After ascending the watchtower, Wu Ji briefly reported the results of his inspection, and then added with a smile: "It's just that a little too idle, one by one hiding in ......the military house (mud hut)" Saying, he thought about it, hugged his fists and pleaded: "Your Highness, anyway, there will be no war this month, why don't you pull the soldiers out to practice drills?" ”

"Drill in this kind of weather?" Nanmen Yang had a strange expression on his face when he heard this.

And in this regard, Yan Mo seems to be surprised, after all, the Yanling army, like the Shang Shui army, is trained in accordance with the requirements for training the Wei infantry, and the training of the Wei infantry has always been rain or shine, not to mention the heavy snowfall, even if it is a knife in the sky, the training still has to be trained, do you really think that the strength of the Wei infantry is innate?

For the sake of his compatriots, Yan Mo briefly introduced the drill outline of the Wei infantry to Nanmenyang, only to hear Nanmenyang dumbfounded.

He finally understood why the predecessors of the Yanling Army and the Shangshui Army were obviously just peasant soldiers temporarily recruited when Xiong Tuo, the Emperor of Xuancheng, attacked the Wei State, but now their combat effectiveness can surpass the main army of the Chu State, the reason is that these two armies have undergone strict training.

Thinking of this, Nanmen Yang said with a smile: "This is good, why don't you count me in?" ”

Hearing this, Yan Mo and Wu Ji glanced at Nanmenyang with a smile, after all, they all knew that at present, Nanmenyang also had a number of troops under his hands that was no less than that of the Yanling Army and the Shangshui Army.

"Drill soldiers?" Listening to the conversation between the three generals under his command, Zhao Hongrun chuckled and shook his head.

To be sure, he was not a cold man towards his loyal subordinates, and since he knew that his soldiers would be bitter enough in such a cold winter, why should he burden them any more?

But then again, it is undeniable that Wu Ji's concerns are also reasonable, after all, let the soldiers hide in the barracks for a month or two, during which they have not fought or practiced, and in the spring of next year, whether the Wei army can still maintain the previous level, this is not guaranteed.

After thinking about it, Zhao Hongrun, who looked at the snow in the wilderness outside the city, suddenly moved in his heart, and a few smiles hung on the corners of his mouth.

I saw him nod and say, "Okay, drill!" …… But let's practice in a different way. ”

As he spoke, under the puzzled gazes of several generals, he reached out and grabbed a handful of snow, pinched it into a snowball in his hand, and then threw it out of the city.

Seeing this, Zong Wei Weijiao, Lu Mu and the others suddenly had a deep meaning in their hearts, and their faces showed a look of great interest.

At this time, I saw Zhao Hongrun turn around and say with a smile: "Pass the order, and the Wei army in the city will conduct drills." ”

Half an hour later, the soldiers in the many barracks in the ice city were all called out by their respective thousand generals and two thousand generals.

I have to say that when these soldiers heard that they were going to perform, they complained and lamented, after all, no one was willing to carry out any drills in such cold and freezing ghost weather.

But when the heralds shouted out the specific items of the drill at the top of their voices, the grievances of the soldiers gradually subsided, and they were replaced by a wave of excitement.

The venue of the drill was set up on the open snow field outside the ice city, and the 5,000 Yanling army led by Yan Mo and the 5,000 merchant army led by Wu Ji stood in their own ranks outside the city, while the rest of the soldiers crowded inside the city and outside the city to watch.

With the order of Zhao Hongrun, who was standing on the wall of the ice city, the five thousand Yan Ling army and the five thousand Shang Shui army quickly leaned over and grabbed a ball of snow from the ground, kneaded it into a snowball, and threw it towards the opposite side.

For a time, nearly 10,000 snowballs came and went, smashing at their respective targets, only to see the 5,000 Yanling army or 5,000 merchant and sail troops tossing and turning, dodging the snowballs of the "enemy" while quickly rubbing the snowballs to counterattack, making this exercise enter the white-hot from the beginning.

"Damn, that bastard on the other side, just staring at Lao Tzu and smashing it?"

"Big eyes six, Lao Tzu knows it's you, don't hide!"

"Ahh......h

The soldiers on both sides, some scolded angrily and some provoked, although they fell to the ground from time to time, or were smashed by the opposite snowball, but this enthusiasm became more and more high.

Gradually, the Wei soldiers who fought outside the city were also itching, and successively joined the camp of the Yanling army and the Shangshui army, and even later, even the newly surrendered 50,000 Chu soldiers under the command of Nanmenyang also joined the fateful battle between the Yanling army and the Shangshui army.

Nearly 100,000 Wei soldiers were running in the snowfield outside the ice city, sweating profusely one by one, their brains were hot, and they no longer looked like they were wilting.

Subsequently, under the guidance of Zhao Hongrun, this snowball battle gradually became high-end, and the Wei troops of the two camps no longer fought as they did at the beginning, and gradually knew how to build snow walls and dig snow roads.

Seeing this, Zhao Hongrun then instructed the guards to invite the military flags of the Yanling army and the Shangshui army, and planted them in the positions of both sides, and told the Wei soldiers on both sides that whoever grabbed the banner on the opposite side would win, and the reward was an extra cent of the spoils after the capture of Juyang County.

Hearing this, the soldiers on the side of the Yanling army camp and the Shangshui army camp were even more morale-boosting, after all, the two were originally rivals competing with each other, plus the victory and defeat and the rewards, they were even more excited, where would they care about the cold.

It's just that no matter which camp the Wei soldiers are, it is not so simple to snatch the opponent's military flag.

Because during this period, there were many reckless and impulsive soldiers who rushed out from behind the cover of the snow wall, only to be greeted by thousands of snowballs on the other side, and almost the whole person was drowned, and finally had to flee back in embarrassment while spitting snow.

This made it difficult to distinguish between Yan Mo and Wu Ji and other generals.

"Your Highness is ...... wise"

Looking at the morale of the two Wei soldiers outside the city, and the heat was bubbling all over his body, Nanmen Yang admired the young King Su beside him more and more.

Just a little trick boosted the morale of the army, and at the same time played a role in training the soldiers.

And the next day, there was no need for Zhao Hongrun to organize it, and the Wei soldiers in the ice city walked out of the city one after another to continue this snowball battle that had not been won or defeated yesterday.

However, today, more than a dozen Chu army scouts from Juyang County saw this scene from afar.

"Huh? The whole Wei army is dispatched, is it to attack my Juyang County? Hurry back to the Shrine ......"

"Wait a minute, this Wei army ...... What are you doing? ”

What appeared in front of the scouts of this Chu army was a snowball battle of 100,000 Wei troops at every turn, and the intensity was so intense that they were only dumbfounded. (To be continued.) )
