…

Sometimes Li Cun has to admit that genetics are really magical.

Qian Guifei gave birth to these children to Li Cun, she is really smart.

Especially Qian Guifei gave Li Cunsheng's first son Li Huan.

This kid is not yet fifteen years old, and he already has more than a dozen inventions.

Be.

Li Cun admits that many of Li Huan's inventions and creations were ideas given to him by himself.

Like a solar heater, like a hand-cranked corn threshing machine, and so on......

And one of Li Cun's most impressive inventions is the improvement of the biogas digester.

In this era, there is no natural gas, which is both convenient and energy-saving and environmentally friendly, and the development of electrical appliances is far from the time when household appliances appear (after all, there is only one small hydroelectric power station in the world, and ordinary people have no access to electricity at all), so people need a lot of firewood for cooking and heating.

If the family has domestic animals such as ploughing cattle, rice and wheat straw, and keep them for cooking, the ploughing cattle will lack forage in winter, and they will lack firewood for cooking.

The invention of the biogas digester can undoubtedly improve this situation to a great extent.

Using biogas for cooking not only saves a lot of firewood, but also saves all the trouble of burning firewood, which is clean and hygienic and convenient.

Biogas can be produced by taking some livestock manure and household waste generated around the house and pouring it into the digester.

At the same time, this has also changed the environmental hygiene, making the home more clean and hygienic and beautiful, raising livestock, and the forage is also sufficient, which can save a lot of firewood.

However, after the biogas digester has been used for a long time, and the pipes and equipment are aging, it is prone to gas leakage, and it is repaired here and there.

And once the biogas is mixed with some air, there is a danger of explosion when it burns.

The most troublesome thing is that the biogas digester has to constantly add raw materials and water, so the garbage in the digester accumulates day by day, and then it has to be cleaned once a month, and every time it is cleaned, it is very laborious, and if it is not operated properly, it may die in the biogas digester, because biogas is toxic.

Also, the amount of material added to the biogas digester is too small, then the gas production is small, when using biogas, the biogas is not enough, the fire power is reduced, the use effect is affected, the feeding is excessive, the gas is sufficient, the air pressure increases, and some aging air pipes are easy to break, and there is air leakage.

At the beginning, when Li Zheng and Qian Guifei and other researchers from the Royal Research Institute proposed the concept of biogas digester, they explained the problems of biogas to Qian Guifei one by one, and asked them to find a way to solve these problems.

In addition, Li Cun also gave a preliminary solution, that is, collective production.

But even in collective production, biogas digesters have the same problems that Li Cun said.

But then again, in this period when there is no natural gas, electrical appliances have not been developed, and cutting wood is too laborious, energy-saving and environmentally friendly biogas digesters are still very valuable.

Therefore, Li Cuncai told Qian Guifei and other researchers from the Royal Research Institute about the biogas digesters, and wanted them to see if they could find a way to solve the hidden dangers of these biogas digesters.

As a result, the speaker is unintentional, and the listener is intentional.

Li Huan, who was only eleven years old at the time, actually used a cantilevered inclined tank with high and low spans that Li Cun did not expect at all, and even in the previous life, which perfectly solved the problem of cleaning up the garbage in the biogas digester.

In addition, other researchers at the Royal Research Institute have picked up the slack, and the Daqian Imperial Court will send professional people to centralize the management of the biogas digester.

Biogas began to be used on a large scale.

In Nanjing, for example, almost 10% of people now have access to biogas.

Moreover, this number is growing.

Of course, Li Cun also knows that biogas must be just an excessive item.

In the future, whether it is the development of electrical appliances or the development of natural gas, it will definitely replace biogas.

But it is undeniable that at this stage, biogas is still relatively practical.

The key is that Li Huan can solve a huge drawback of the biogas digester at the age of eleven, and Li Cun can see that Li Huan, like his mother Qian Guifei, is a genius inventor.

After that, as long as there is a chance, Li Cun will talk to Li Huan and inspire Li Huan.

As a result, Li Huan really lived up to Li Cun's high hopes and helped Li Cun develop a lot of useful things, including greatly facilitating life, and at the same time making people's daily life more colorful, no longer sunset, and promoting the production efficiency and working hours of various industries and accelerating the development of various industries and service industries.

It can be said that Li Huan is the Edison of this era.

The key is that Li Huan is only fifteen years old now, and his future still has infinite possibilities.

Li Cun's children who came by train this time did not have Li Huan, they were Li Huan's younger siblings, and Li Huan was now preparing to demonstrate the latest generation of trains to Li Cun with his mother Qian Guifei.

Qian Guifei gave Li Cunsheng's third son Li Wei, and after meeting Li Cun, she pulled Li Cun's sleeve and said, "Father, go, get on the train, we will take our father to the test site." ”

Before Li Cun could say anything, Li Cun's pro-army leader, that is, the Tiger Ben Army, was in charge of Yang Yizhong, so he decisively stopped him: "Official, no, the gentleman does not stand under the dangerous wall, after all, this train is still in the experimental stage, it is difficult to guarantee that there will be no problems, and if the official family takes the train, it is not conducive to our guards, so it is better to take a carriage to go." ”

I think that at the beginning, when Li Cun transferred Yang Yizhong to be the leader of his pro-army, everyone felt that Li Cun was just a delaying tactic, and Li Cun would never hand over the Tiger Ben Army, which was related to the safety of his life and even the safety of the Daqian Dynasty, to the hands of a general, and even Yang Yizhong himself felt that Li Cun was a bright rise and a secret descent, and his career was completely over.

What made everyone's eyes shatter was that Li Cun really handed over the 100,000 tiger army to Yang Yizhong.

In that year, after the military reform, Li Cun selected the elite of the 100,000 elites from the more than 1.5 million troops in the country at that time, formed his own pro-army, and used the "Tiger Ben Army", which was crucial to the Daqian Dynasty, as his pro-army name.

- The rest of the cadre army, although in order to flaunt the exploits of their army in the War of Founding of the People's Republic of China, also retained some of the original names, such as the Beiwei Army, the Tabai Army, the Youyi Army, etc., but the official titles are actually all replaced by numbers, for example, the Youyi Army became the Ma First Army, the Beiwei Army became the Ma Second Army, and so on.

In addition to being composed of elite soldiers and strong generals, the Tiger Army was also the only one among all the armies of the Daqian Dynasty, with two armies (that is, 20,000 men) equipped with the most advanced firearms such as flintlock muskets, red-coated cannons, and improved tiger squat cannons, as well as a group army of 50,000 elite cavalry.

It is no exaggeration to say that the Tiger Ben Army is the strongest army in the world, and there is no one.

And Li Cun did not hand over this world's strongest army to Yue Fei, Han Shizhong, Wu Jue, Liu Qi and other generals, or to Zhao Han'er, Kong Xuanzi, Erpolezi, Zhang Goudan, Sun Sandu and other his absolute cronies, as well as Wu Lan, Zhao Li, Li Yanxian is also a good choice, but handed over the tiger army to Yang Yizhong.

Undoubtedly, this must have reassured the hearts of those generals, whether it was Zhang Jun, Liu Guangshi, or anyone else who had joined the Zhao and Song dynasties, since then, all of them have served in the Daqian Dynasty with peace of mind.

But in this way, on the contrary, the civil and military officials of the Daqian Dynasty could not sit still.

Seeing that Li Cunzhen was going to hand over his safety and the Tiger Ben Army to Yang Yizhong, a second-line general who had just surrendered from the Western Song Dynasty, the civil and military officials of the Daqian Dynasty advised Li Cun to think twice before acting.

There are radical ones, like Yue Fei, who bluntly said that Yang Yizhong is unreliable and must not accompany the official family.

Like Kong Er, he was stunned, and he directly asked for orders to Li Cun as the leader of the pro-army.

Also having the same idea as Kong Erzi are Wu Luan, Yan Guangxiao, Zhang Goudan, Erpolezi, Wang Sheng and other Li Cun's original pro-army leaders.

But Li Cun took into account:

In history, Yang Yizhong had a very good performance in the suppression of thieves, the Pingmiao Liu Mutiny, or the battle against Jin.

Yang Yizhong has experienced more than 200 large and small battles in his life, and he has charged forward in almost every battle, and has rarely been defeated.

It is precisely because of this that after the Miao Liu Mutiny in history, Yang Yizhong was finally favored by Zhao Gou and gradually took charge of Zhao Gou's Su Wei pro-army.

After Yang Yizhong took charge of Zhao Gou's pro-army, he not only completed the defense work excellently, so that Zhao Gou was never as displaced as in the first half of his life, making people chase like a lost dog, but also often assisted other generals to fight against the puppet Qi or the Jin army.

In this way, Zhao Gou, who did not trust the generals and was extremely suspicious, handed over the Sanya (that is, the Zhao and Song Dynasty's palace divisions, infantry divisions, and horse military divisions in charge of the world's soldiers and horses) to Yang Yizhong, and Yang Yizhong, who was in charge of the central military and political power, stood for nearly 20 years.

After the Jin people broke the alliance, Yang Yizhong participated in the famous Battle of Zhegao, and he became one of the few Song generals who defeated the Jin Wushu with his long axe soldiers.

Of course, because of Zhang Jun's greed, he was ambushed by the Jin army when he marched into Haozhou, and Yang Yizhong also suffered a big defeat, which made his resume stained.

But on the whole, Yang Yizhong is definitely one of the few generals in the Southern Song Dynasty who are good at fighting, brave to fight, well-deserved generals, and first-class commanders.

Later, Wan Yan Liang killed Wan Yan and usurped power, and in order to stabilize his regime, he led the army to invade the south.

Yang Yizhong, out of consideration for resisting the enemy, put forward the "Ten Strategies for Preparing for the Enemy".

But this was framed by Yang Yizhong's old comrade-in-arms, that is, Zhao Mi, who was also a general under Zhang Jun, as "happy success".

Yang Yizhong knew that Zhao Gou was suspicious, and he had been in power for a long time, which was easy to arouse Zhao Gou's suspicion, so he took the initiative to resign.

But in the following years, Wanyan Liang continued to invade the south, and Song and Jin began to fight again.

In this process, the Song army had many defeats, and those literati who did not understand military affairs in the small court of the Southern Song Dynasty invited Yang Yizhong out several times to help the emergency.

Yang Yizhong can fight well, has a very good view of military affairs, and is also familiar with the military situation of the Song and Jin dynasties, and he is the oldest (at that time, the generals of the same period as Yang Yizhong were basically all abolished by Zhao Gou and Qin Hui), and the generals obeyed orders, so they played a great role.

Yang Yizhong finally worked in the Song army until the second year of Xiaozong's reign before he died of illness at the age of sixty-four.

This can be said to be a huge miracle in the small court of the Southern Song Dynasty, which had a high degree of distrust of military generals.

Yang Yizhong's strategy is conservative and more defensive, but he often takes the lead in battle and performs very bravely. He has strong coordination skills and is good at handling relations with the imperial court, and is very suitable for a position such as defense minister.

In addition, Yang Yizhong also has a lot of experience in ordnance manufacturing, and once invented the Mahuang crossbow to make up for the lack of the enemy's bow, in other words, he is also a general who can accept and even take the initiative to research new weapons.

Regarding Yang Yizhong, the biggest controversy is estimated to be his performance in the Yue Fei case and the peace negotiation in history.

Yang Yizhong is the supervisor of Yue Yun and Zhang Xian, and he is Zhang Jun's favorite general, and he has a good relationship with Zhao Gou, so many people suspect that he was also involved in framing Yue Fei.

In addition, after the Song and Jin Dynasty negotiated peace, due to the persecution of Qin Hui, many generals of the Southern Song Dynasty were transferred from active duty, and only Yang Yizhong was able to take charge of the front division of the palace for more than ten years without falling, which has to make people suspect that he had an ambiguous relationship with Qin Hui.

Whether Yang Yizhong is really a traitor and a "eunuch", Li Cun is not sure.

But what Li Cun knows is that

Yang Yizhong opposed the killing of prisoners, and this kind of thing was very common in the Song army at that time, including Han Shizhong, only a very small number of generals such as Yue Fei did not kill prisoners, and Yang Yizhong was one of them;

Yang Yizhong did not agree with the diplomatic policy of cessing land and seeking peace advocated by Zhao Gou and Qin Hui's monarchs, and he strongly opposed the cession of the strategic place of Shangyuan, and hoped to negotiate with Jin on the basis of "returning the old soil, losing the coin, and restoring the boundary of Baigou";

Yang Yizhong loves talents very much, and has defended Li Xianzhong, Dong Xian and other generals, it can be said that the small court of the Southern Song Dynasty later had the strength to fight with the Jin State, and Yang Yizhong contributed a lot.

The above facts show that Yang Yizhong is unlikely to be a despicable villain like Qin Hui, and the reason why he is on the side of the official is likely because of his close relationship with Zhang Jun and Zhao Gou, as well as the limitations of the situation at that time.

Even so, what Yang Yizhong did in the group led by Zhao Gou and Qin Hui was more of a "plotter" than a "plotter".

The history of the Song Dynasty did not put Yang Yizhong and Zhang Jun and Liu Guangshi in the same category, which seems to explain this.

Generally speaking, Yang Yizhong was a more successful political soldier than Yue Fei, Han Shizhong, and Zhang Jun, and he was able to do a good job in army building to the greatest extent without touching the ruling faction of the imperial court, and retained the strength of the first war for the small court of the Southern Song Dynasty.

Moreover, Yang Yizhong has been by the side of Zhao Gou, who has been extremely distrustful of military generals and unsympathetic, for more than ten years, whether it is his loyalty or his scheming, Li Cun admires.

The Tiger Army is different from those armies of the old era, it is a new-age army dominated by firearms.

To be the commander of the Tiger Army, you must be the kind of general who has a very flexible mind and can accept new weapons and equipment and new tactics.

At the same time, as Li Cun's army, whether it is Li Cun or the Tiger Army, nothing can happen, so as the commander of the Tiger Army, he must not be rash forward, and he must be extremely steady.

Yang Yizhong undoubtedly met all of these conditions.

And Yang Yizhong has proved in history that he is definitely a loyal person, even if the object of his allegiance is an extremely bad emperor like Zhao Gou, and even later he has resigned because of Zhao Gou's suspicion, when the small court of the Southern Song Dynasty needed him, he also came back to serve without hesitation, and did not make a petty character.

At this point, I have to say that Yang Yizhong is indeed much more mature than Yue Fei.

In this life, because Li Zheng Miao and Liu destroyed the Western Song Dynasty and arrested Zhao Gou before the mutiny, therefore, Yang Yizhong and Zhao Gou did not have much intersection, and Zhao Gou did not appreciate Yang Yizhong as he did in history, and the person who really appreciated Yang Yizhong was Li Cun, and Li Cun was the Bole of Yang Yizhong who had not been reused before.

In addition, Li Cun is now the only emperor in China.

In this case, Li Cun believes that Yang Yizhong will definitely be loyal to him as he was loyal to Zhao Gou in history.

No.

Li Cun asked himself, his own personality charm of building a unified dynasty from scratch is not the same as Zhao Gou, and he is more popular than Zhao Gou, and he has never been as merciless as Zhao Gou, and he is not as unkind as Zhao Gou, so Yang Yizhong should be more loyal to himself.

Therefore, despite the advice of many people, Li Cun still insisted on handing over the Tiger Ben Army to Yang Yizhong to be under control.

But then again, in the end, the Tiger Ben Army is the foundation of Li Cun's life, and it is also related to the safety of the Daqian Dynasty, and the civil and military officials who advised Li Cun are all well-intentioned.

Based on these, Li Cun finally adopted the compromise suggestion put forward by the civil and military officials, and transferred Sun Sandu, who had completed the reorganization and teaching of the Western Song Dynasty army, back to serve as the capital supervisor of the Huben army, and at the same time, he transferred Zhang Goudan who repeatedly asked for his life back to serve as the chief of staff of the Huben army, and transferred the second pole who would rather be a small soldier by Li Cun's side than return to Li Cun's side to serve as the deputy commander of the Huben army, giving the Huben army sufficient insurance.

However, although Li Cun transferred back three cronies and generals to help Yang Yizhong control the Tiger Army, Li Cun mainly discussed the training and tactics of the Tiger Army.

Moreover, even if Li Cun does not bring his favorite two generals, Yang Zaixing and Yao Xing, he will definitely take Yang Yizhong with him to protect him.

It even appeared when Li Cun was only guarded by Yang Yizhong alone.

Li Cun's trust and importance to Yang Yizhong are seen by everyone, and Yang Yizhong can feel it.

Yang Yizhong didn't say anything on the surface, but while training the Tiger Ben Army to scream, he also arranged Li Cun's defense work to the ground, never letting Li Cun be in the slightest danger.

Just like now, although he knew that it was not risky for Li Cun to take the train to the test site, Yang Yizhong still insisted that Li Cun take a carriage that he could control any danger, even if Li Ao and other princes and princesses fought with Yang Yizhong, Yang Yizhong would not give an inch.

Although Li Cun also felt that there was definitely no danger in taking the train to the test site, it was Yang Yizhong who was too careful, but Li Cun still chose to follow Yang Yizhong's arrangement.

Li Cundu spoke, and Li Wei and the others could only glance at Yang Yizhong, who was in the ancient well, and then prepared to follow the carriage to the test site.

However, Li Cun saw that Zhu Fengying and other women were very interested in the train, so he asked Li Wei and them to take Zhu Fengying and other women to the test site by train, leaving only Zhu Lian and Yun Erzong Ji to accompany him to the test site in a carriage......
