Due to the shortage of food, Datang even suspected that Datang would not survive this winter.

But under Lin Zifan's Zhongzhong measures, not only was the food problem solved, but even the two kingdoms of Chen and Wu were defeated and the land of the two counties was taken, which was not happy, when should I be happy?

Moreover, if it weren't for the fact that it was winter at the moment, Datang could be called a thin population, and General Huo Da, Bi Xia and others would even have to go all the way north to fight the two countries.

However, due to various reasons, even if they continue to attack the city at this moment, no one can defend it, and the supplies cannot keep up, so they can only give up.

However, even so, Chen and Wu Erguo are in danger at the moment, and the court is up and down, and there is a lot of noise!

The civil and military officials of the two countries were all trembling, and the emperor was furious!

But this is useless, this fiasco has caused a lot of losses to the two countries, and even the generals have been captured alive, and it is difficult to find people to fight in the middle of the country, how can this be fought?

Especially, when the news came that the Tang army had broken through one city after another, the emperors of both countries almost fled!

Fortunately, in the end, the army of the Tang Dynasty only took a county, and then began to defend it allegedly, otherwise the two emperors would really be ready to run away.

After all, in a short period of time, they have no way to organize a reliable army to fight against the Tang Dynasty, especially under the 'bombardment' of unknown things, the city cannot be defended at all, and there is no way to fight!

Now that the Northern Army of Tang Town and the Praetorian Guard have no choice but to stop at the same time, the two countries also have a little respite, and while frantically recruiting troops, they have also begun to build fortifications within the country......

After all, in the past, it was the county town that was captured at this moment to fight against the Tang Dynasty, so the main fortifications were in Qingbei County and the Weiwu County of Wu State.

But now that Qingbei County and Weiwu County have become the territory of the Tang Dynasty, they naturally want to rebuild the border defense line.

As for sending troops to regain lost territory...... For a short time, they didn't dare to think so.

It's already good not to be attacked by the Tang army again!

Even, the people of several counties bordering Qingbei County and Weiwu County began to flee their ancestral lands where they had lived for generations......

There's no way, the barbarians have already hit the doorstep, who is not afraid?

In order to prevent accidents, it is better to run away first......

......

The northern border has won a complete victory, and the halls are full of confidence! The officers and men in the east, west, and south directions have also gained confidence in their hearts, and they have started a battle with great momentum!

After gaining a firm foothold in Qingbei County and Weiwu County, General Huo Da and other generals began to return to the DPRK one after another, while the Zhenbei Army was directly divided into two, taking over Qingbei County and Weiwu County respectively, and opening up the land of the two counties to build a defense line together!

After all, the Praetorian Guard is the empress's personal guard, and it is also the existence of guarding Chang'an on weekdays, so it is impossible to hang around on this border all the time......

The tension of the war eased, and Lin Zifan also breathed a sigh of relief, at least he didn't have to worry about the war in the north often, which was already commendable.

The promotion of the clay kang is also very fast, after all, this thing is not difficult, and you can learn it after watching it twice normally.

If one person learns, he will soon be able to learn all the people in the village, because the problem of being too cold in winter and freezing to death for many 'single' men will be gradually solved.

Therefore, for the next period of time, in addition to flirting with the empress and acting as a teacher at the Lily of the Valley Academy, the rest of his time was spent researching new gadgets......

Smoke!

The tobacco has been back for a while, but Lin Zifan has never had time to get the cigarettes out.

But in this winter, apart from teaching and accompanying the empress, it seems that there is nothing to do! In addition, the weather is cold, in addition to drinking wine and the earthen kang can be warm, many times, smoke can also refresh the mind and relieve the cold!

So, Lin Zifan decided to take the time to get the cigarettes out!

Cigarettes are mainly composed of three parts, tobacco shreds, cigarette butts, that is, cigarette butts, and paper wrapped in cigarettes.

Of course, if you want to look high-end, you need high-end packaging.

Tobacco and paper are not difficult, Lin Zifan has this thing in his hands, and there is no problem with the paper mill specializing in producing a batch of paper used to make cigarettes, and even the paper shell of the packaging can be solved!

But there are also problems, that is, cigarette butts, and plastic ......

As we all know, smoke is the most afraid of moisture, after the humidity, the texture and taste will all change, and even after a little longer, it will become moldy!

Therefore, outside the packaging of cigarettes, there will be a thin layer of plastic seal. In order to prevent moisture......

There is another problem, that is, the pattern problem, such as making a cigarette packaging box, but the result is white, and there is no pattern for anything, so it is too unforced?

In Lin Zifan's opinion, the cigarettes he made must be high-end products, high-end goods, how can they not look a little forced?

Another is cigarette butt, which is generally made of organic fiber cotton material, which can be regarded as a kind of treated cotton, or sponge.

In addition to being more convenient when smoking, another is to filter some harmful substances, for this reason, some brands of cigarette butts will also add some activated charcoal, the purpose is to further block the intake of harmful substances.

Cotton, Datang has it, but ordinary cotton is not easy to use, as for the sponge...... That thing, Datang's craftsmanship can't be made!

Therefore, these problems need to be overcome by Lin Zifan.

As for why Lin Zifan makes cigarettes...... Sorry, this thing is actually not difficult, and the structure is very simple, as long as there are materials, normal people can make it.

What's more, even if you don't have a cigarette butt, you can smoke it by chopping and frying it directly, wrapping it in paper, and then inserting it on a bamboo tube!

You can even smoke it directly without using a bamboo tube, but this is contrary to Lin Zifan's original intention of wanting to make high-end cigarettes.

Come to think of it, plastic can barely be made out of rubber, but it's not as tall as the outer cover of a modern cigarette.

It's not impossible to have a pattern, such as carving a batch of stamps or something, and then stamp the imprint and pattern on the package.

But Lin Zifan really has no clue about the material of the cigarette butt.

Therefore, his eyes rolled: "Salted fish system, you come out! After diving for so long, it's time to come out and bubble, the starting point works, right?"

"Otherwise...... What do I want you for?"

[Don't look for me, I need to be quiet lately......]

"Do you still need to be quiet?" Lin Zifan raised his eyebrows, sensing that something was wrong: "What's wrong with you?"
