"How big is the play?"

Equation, who was going to rest, knew that he didn't want to leave in a short period of time since he entered this door.

The sky is big, the earth is big, and it is no bigger than the wartime that happened on the front line.

Smart people know how much benefit it will bring to the Wu Dynasty if they can end this war before the snow melts.

The name of the "forbidden land" in the northern part of the harsh winter will completely turn from theory to reality.

As a result, if other countries want to carry out a "Northern Expedition" against the Wu Dynasty, the original eight-month window will be completely reduced to six months.

Six months......

With the power of one country, nothing can be done, unless it can win over the Liao State, the Ming Dynasty, and the Later Tang Dynasty like forty years ago, and many countries unite to encircle the Wu Dynasty with absolute superiority.

Otherwise, no one in Hexi will be able to take it.

Such a situation will end with the development of history, but as long as it can exist for seven or eight years, the Wu Dynasty itself will be able to develop, and then it will not be passively beaten, but the Song Dynasty will consider how to defend.

"What is this, just a young son of the Cao family, there are two or three princes who died under my Chao Tie cavalry in history!" Xia Heng sneered.

Big things are small, but big things should also be done.

Whether there is a solution to the equation or not, whether people are needed or not, it is not clear for the time being, but at the beginning of the year, the second generation of the group around the equation has now been packed and thrown into the western suburbs.

"In that case, let's get started!"

No matter how big a thing happens, this year's Hundred Flowers Banquet should not be excited, and he clapped his hands with a little excitement in his heart, "The first question, when will the single-day output of the hand stove explode, and how much can it burst up to?" ”

There are many cold protection methods in later generations, but none of them were developed in a short period of time.

Especially in the next cold winter, there is no specific data, but the equation that the body has already told is that the down jacket is not to say anything, and it can't withstand the cold of falling below minus ten degrees.

In terms of cold protection, about zero degrees, down jacket is the best, lightweight, warm, comfortable, can fall below minus ten degrees, the fluffy structure of down can not bear it at all, the best choice is fur, sweaters, and other animal and plant fibers, but these are obviously not made in a short period of time, and it is better to peel a few more sheepskins to send to the front line.

"Those craftsmen in Xuanbai Building have been pressed over, with this group of people, plus the blacksmiths and coppersmiths we transferred from the city, skilled hands should be able to get out of eighty groups, and it should be no problem to scatter a little one hundred groups, four thousand pieces a day is not a big problem."

Huang An looked serious, "Over there in the blast furnace, the messy demand has been scrapped, one furnace has been produced this morning, and there will be two furnaces later, polishing this piece of carpenter, stonemason, jade craftsman can also do it, the number has been adjusted, the key is the mold, the mold is done, and it is not a big problem to produce 6,000 embryos a day!" ”

"As for the time, if everything goes well, it will start to explode in three days, and it will reach the highest in six days!"

This is almost the era of artisanal, the capacity is at its limit.

In later generations, many operations are very simple, that is, they are borrowed from abrasives and sophisticated tools, and now there are not so many craftsmen in their hands, and everything is delicately worked through hammers and tongs to run in little by little.

The first thing to solve in tool improvement is the material, iron is definitely not good, it must be steel.

And steel, which is not enough for weapons, to create tools for craftsmen, when the time comes, the first to jump out against it is probably the craftsman.

"For the matter of the hand stove, you pick one person to be fully responsible and cooperate with the people Yang Yingzhi!"

"No problem!"

Huang An is already in the manufacturing library, there are not thirty officials under him, there are still more than a dozen, just pick one out, and it is not a big problem to be in charge of the hand stove.

"And we're going to do something else now!"

Equation stretched out a finger, "Developed a new, easy-to-carry thermal product!" ”

"Master Fang, do you really have an idea?"

"What are you talking about, I have long said that Master Fang must have a way!"

"Can you still develop?"

Invite the equation over, that is, the bigwigs want to see if the equation that is good at creating miracles can create miracles, but everyone does not look at the probability of the birth of this miracle.

Miracles, they can appear at will, so can they still be called miracles?

But who would have thought that just after getting the news equation, he threw one out directly, and it was inevitable for a while that people would think, was the equation already planned?

"I already have an idea, but whether it can be achieved in the end, no one can say, it takes a lot of experiments, if it succeeds, it is naturally the best, vice versa......"

Equation shook his head, "Anyway, let's do it first!" ”

For a while, the equation could think of using lime heating to make a simple heating package, which would definitely not be stuffed on people's bodies.

But once the departure hot pack is made, it will solve the problem of the sergeant's supply in the field.

Don't underestimate a bite, a hot one.

In addition to protecting from the outside in, the means of keeping warm from the inside to the outside are also a way out, and a bite of food that can provide calories without ignition in the wild will also avoid the possibility of being discovered as much as possible while providing heat.

"You think first!" Yang Yingzhi said.

"Saltpeter can make ice, lime can generate heat, you should have seen this situation!"

Kyushu does not produce cement on a large scale, but it has obtained semi-quicklime through various wild roads, and lime water itself is an important material for rainproof at the moment, and the amount may not be much, but there must be a lot of it.

"Lime can indeed heat up, but the heat of lime is not easy to control, and one carelessly ......" Yang Yingzhi wanted to say and stopped.

If you haven't eaten pork, who hasn't seen a pig run.

"So we need to experiment, through the experiment to find a way to control, our demand is not high, just a hot food!"

"Imagine that the lime heats up, heats the food, the originally cold steamed buns become soft, and the cold water in the mouth becomes warm water, what kind of layout will this bring to the cavalry who have been active in the field for a long time, and as long as it is small, the amount is controlled, and it can be used anytime and anywhere, then it is not a problem to replenish the body temperature through warm water!"

With the current process, the corresponding heating package must be manufactured, but the equation does not need to be heated thoroughly, it can cut away the snow water, and the entrance feels warm.

As for the boiling water, it is also drunk by the Northland warriors in winter, and it is not the direct entrance of well water on weekdays?

Nowadays, it is snow water that needs to be melted, and how to find clean and drinkable snow in the field is itself a subject of military investigation, and the equation to be done is to heat it.

"If this method can be realized, it may have a greater impact on the war than a hand stove!" Yang Yingzhi was selected from the army, so he naturally understood the difficulties of supply in the wild, and he understood the benefits of eating a mouthful of hot food in the wild in winter.

In the final analysis, it is the lack of portable heat source, the furnace solves the external, the hot food solves the body, and the field will no longer be as cold as it is.
