Lei Ting said: "Your Majesty, you might as well think about it, if a whole platoon of soldiers were all equipped with lever-type flint and fired together, what would be the result?" -- This is how the country was opened at the end of the Qing Dynasty, and the Opium War was also opened in this way......

In an instant, Hongli's entire momentum changed, and the entire study room was like a low air pressure. His parents died early, and he was sent by the state to study abroad, and went to the most developed and freest country in the world, and also the most preach human rights and democracy, but in that country, he really saw the racial discrimination that he had never seen before, even if he obtained a doctorate with the highest honors, he could already feel the discrimination hidden under those white skins - so he chose to return to China, but unfortunately after returning to China, he was betrayed by his most trusted girlfriend and his mentor......

Thinking of this, Thunder couldn't help but feel a gloom in his heart. Immediately, he became energetic again, but he came to the Qing Dynasty! If he didn't change history, what would he do? I was simply sorry for God's favor!!

Thinking of this, the spirit of thunder explained these industrial revolution materials to Hongli a hundred times, "This is a steam train and a railway, once it comes out, its speed can reach up to half an hour, and it can run a hundred miles!"

Hongli was shocked, he traveled 100 miles in half an hour, and couldn't he travel 2,400 miles in that day?

Hongli hurriedly asked: "How many soldiers, how many ordnance, how much grain and grass can this car hold?!"

Lei Ting thought for a while, and then said: "The steam train can have at least twenty or thirty carriages, and one carriage can carry a maximum of ten tons!"

"Ten tons??" Hongli frowned, how much is this? Our Emperor Xià, I have never heard of this modern unit of measurement.

Lei Ting hurriedly said: "One ton is equal to two thousand catties!"

Hongli's eyes lit up in an instant, one ton and two thousand catties, and ten tons is not 20,000 catties? Isn't twenty or thirty carriages more than 100,000 catties of grain? Based on the calculation of five catties of grain per soldier per day, a steam train can carry 50,000 troops for a day's food?

Thunder hurriedly added: "But if you have the maximum load, the speed will not be the fastest." ”

Hongli nodded slightly, this is not difficult to understand, "What Qing Zhi said, I know it in my heart." "--There are too many good things on it, and it needs to be digested slowly--and the cost of this steam train is also very expensive, and the train itself is just that, the railway ...... It requires a large number of wooden rails and migrant workers, and it is undoubtedly a huge project to be laid! It will take many years to complete, and it will take extremely laborers and material and financial resources. In particular, the railway from the capital to the southwest will not be able to start construction within five years. However, you can try to build a short section of the railway first.

Hongli had an idea in his mind......

This **, Thunder's mouth is like a river, and his mouth is almost dry.

Even the black technology invented during the first industrial revolution is really not a small number, steam-powered land and sea vehicles, textile machines represented by the Jenny spinning machine, various strafing on the principle of flint and the proportion of gunpowder on the principle......

However, our Emperor Xià is obviously more interested in various black technologies that can be used in military warfare, but all kinds of things in the field of people's livelihood have also shown enough attention.

Of course, Hongli seems to be more interested in the steel carriage brought by Ming, because after all, those flintlocks, steam trains, and steam ships are only stored on paper and in theory, but the steel carriage is indeed there! Moreover, Hongli has also seen with his own eyes the powerful ability of the steel carriage -- Lei Ting personally stepped on the accelerator and drove the "steel carriage" in the mouth of His Majesty the Emperor to Qingyan, Kyushu.

However, Lei Ting cautiously said that it is too difficult to think about cars now, although as a doctor of physics, he understands the principles here, but it does not mean that he can come out! Rubber and fuel These two major problems will take a long time to solve, and the steel used in automobiles is not ordinary steel, especially the engine part, which must be a sufficiently developed heavy industry to smelt the steel needed for the engine. The iron burned in the kilns of the Qing Dynasty was used to make engines? That's a joke!

The tech tree has to climb from the bottom! If you want to climb to the sky in one step, it is simply a fool's dream!

Of course, these "big disrespectful" words, Thunder didn't dare to say. He just euphemistically said that if the development of Qiē is smooth, it should be possible to produce a car with use value in 20 years -- and it is only with use value! If you want to compare it with his military-level off-road vehicle, the performance must be very different!!

However, Thunder still tells about several "carriages" that can be quickly released - that is, bicycles, and human-powered tricycles, all of which are the same in principle. However, without rubber, the comfort will undoubtedly be greatly reduced...... There is also a brake device, although it can be done by hand, but it undoubtedly requires a relatively high level of blacksmithing. However, it should be possible to come out with a rudimentary version of a bicycle and a tricycle -- but these two things, in the opinion of modern people, can only be used in the field of people's livelihood.

However, Hongli does not think so. He felt that these two things could almost replace horses! And these things didn't need to eat grass and drink, and they wouldn't get sick! The cost of silver was much cheaper than raising horses!!

Lei Ting is different from Hongli, he is not a warmaker, and he also believes that it is important to improve the people's livelihood in the backward feudal era. In terms of clothing, food, housing and transportation, he proposed four hackers, spinning machines, hybrid rice, cement bricks, and the bicycle tricycle just mentioned.

As a Ph.D. in physics is equivalent to a Ph.D. in biology level of Thunder, these are easy for him to do, oh...... Hybrid rice is also a little time-consuming, and although there are ready-made results in modern society, it will take two or three years to replicate them.

Hongli is also quite interested in this so-called hybrid rice that can increase the yield of rice by several times, why is there a rebellion in the world? Is it not because some people can't have enough to eat? If we can solve the problem of eating for the people of the world, this is even more important than what I said before! Moreover, what is the most important thing in fighting a war is logistics, and the most important thing in logistics is grain and grass! A hungry person cannot fight.

This ** monarch and minister played right, which made the history of the Qing Dynasty turn a huge turn!

The rise of an empire starts today, from the twenty-third year of Qianlong!!

On the same night, there was also a terrible scream in Haiyan Hall, a terrible scream like a cat being stepped on by its tail - Humming was so distressed that she couldn't help it! )
