"Well, this thing is simple and simple, but it's actually difficult to say, if I don't put the finished product in front of you, you probably can't think of it for decades and only need two crystal pieces to achieve this effect, but as long as the finished product is disassembled in front of you, it can be made at once. But the role of this thing in the march and war is too great, if our army has it, and the enemy army does not, it can play a huge role and effect, so this thing is still hidden first, if too many people know, others are likely to copy it, and we will not have an advantage. Cao Yi explained.

"Indeed!" Wang Zhiyuan said with emotion, as an old Zhending army commander who once commanded the army and horses to destroy the two countries in the battle of the Great Yan Dynasty to unify the world, he can realize the strategic significance of this Qianli Divine Mirror and the important role of the enemy's first opportunity. However, marching and fighting is not just a simple addition or subtraction of numbers, it is often one step ahead, one step ahead, and the lagging side will generally be pressed to the ground and chased and beaten until defeat.

"Last time, Gongye Yuanzhou was attacked, it's hard to say that next time the Xinghuo secret camp was attacked by someone, so the secret camp must be equipped with this clairful mirror, the two guard towers at the main gate, and the three guard towers on the other three sides, all of which must be equipped, so that it is more convenient for the sentry to observe and guard, and it can also expand the sentry's vigilance range and reconnaissance ability, and can detect enemy attacks or sneak in in advance. If there is an ambush or attack in front of the guard, it can also directly burn wolf smoke to warn in advance, and the camp can also go to the rescue immediately. Cao Yi said seriously to Liu Baiqing, indeed, this Thousand Miles Divine Mirror can play a great role in defense, reconnaissance and early warning. This can also improve the safety of the transport fleet.

Liu Baiqing nodded heavily, sighed and said, "If Yuanzhou had a Thousand Miles Divine Mirror on the day he was ambushed and killed last time, it would probably be able to minimize our losses." ”

Cao Yi smiled bitterly: "Actually, I already know how to make this thing, but I have always felt that our territory in the Great Yan Dynasty is quite safe, and it is far away from the border, so I don't have the idea of being prepared for danger in times of peace, this is my dereliction of responsibility, there are a total of ten Thousand Miles Divine Mirror made this time, it should be enough, Uncle Wang, you take one over, Qingyun Pavilion I will keep another one here, and the remaining eight Starfire Secret Camps will be taken over first, be careful not to lose it or be snatched away, at least for now, This is a strategic resource that only we have, if someone with ulterior motives obtains this thing, and then observes the Spark Secret Camp on the high mountains on both sides, then we have no secrets at all, everything will be seen in the eyes, then we can't call it the secret camp, change it to the Spark Ming Camp! After speaking, Cao Yi couldn't help laughing at himself, but the facts were indeed as he said.

Liu Baiqing was quite happy when she heard that the remaining eight would be given to the Xinghuo Secret Camp at first, but after hearing Cao Yi say this, she unconsciously became solemn, and said seriously: "Don't worry, Childe, I naturally know the terrible things about this Thousand Miles Divine Mirror, and I will definitely take good care of this thing!" ”

Cao Yi smiled indifferently: "But sooner or later, this thing will be known and familiar to others in the end, but if we can delay it a little later, it will be more beneficial to us, so let's try our best." ”

Liu Baiqing nodded, but then Cao Yi's face became serious, and he said to Liu Baiqing: "Bai Qing, the training of our Spark Secret Camp should be accelerated and aggravated, and when appropriate, stimulate them a little, and on the premise of not hurting the fundamentals, they will be stuck on the edge of the maximum amount of training they can bear, and add tonic medicine to their diet to replenish the vitality they have lost due to training." I have already reported to Governor Yang yesterday, and he also said that if he finds anything, he will give us the information and address of those gangsters as soon as possible, and will issue a reward notice, and then we will be able to become famous and personally go to kick these gangsters, so the training in the secret camp must keep up in time. ”

Liu Baiqing said with an embarrassed face: "Childe, there is nothing wrong with increasing the amount of training or anything, but if you add tonic and other big supplements to your diet, it is okay for one person, but there are five hundred in the camp, and they eat like livestock, and the appetite is too big, I am afraid that this will be a bottomless pit at that time, and we are currently in such a short supply of funds......

"You don't have to worry about the financial problem, before you came, I found a way to make a fortune, No, these things in the yard, called soap, will be an important source of income for us in the future, and then this thing will be directly sold and operated in the name of the Taibai Chamber of Commerce, but in the early stage, you can use the Zuixian Building to enhance popularity and open the market."

Wang Zhiyuan looked at these things in the yard, that is, the soap that Cao Yi said, and didn't know what he was thinking, while Liu Baiqing was more direct and asked: "Childe, this is just a thing to clean the body and hair, will it really be an important source of funds for us?"

Cao Yi smiled confidently and said: "Don't look at this thing is inconspicuous, but it is a profiteering item, if we do a good job of secrecy, this will also be our unique product, the entire Great Yan Dynasty can not find a similar item better than it, and since ancient times, it has always been a woman's thing to make the best money, rouge gouache, silk and satin, gold and silver jewelry, why are these things always so in demand, just because women like these three things, and our soap, I want to think of it as something that is popular throughout our Great Yan Dynasty, and all famous ladies and rich ladies like it. As for the specific effect, it's up to you to try it yourself. ”

Cao Yi waved his hand and asked the old mother in the yard to bring two basins of hot water, then took out the cooled and solidified soap from the mold and put it aside, and stretched out his hand to show it to Liu Baiqing and Wang Zhiyuan, "You see, in order to make it more lubricated when it expands and contracts, this clairmile mirror is greased, I think you all have stains on your hands, right?" ”

Liu Baiqing and Wang Zhiyuan both nodded, and at this time, the red sleeves no longer needed to look into the distance with the clairglass mirror, and turned to look at Cao Yi, indeed his hands were now greasy.

Cao Yi washed his hands with hot water, and after washing it, he showed them his hand again and said, "You see, because of the grease, it can't be washed clean just by washing with water, and it is still covered with grease." Usually, if you don't use anything, you have to wash it several times or a day or two before it is completely clean. Either soap, plant ash or pancreas can be cleaned quickly, right? ”

As everyone nodded again, Cao Yi continued: "But the three things I said are not very easy to store, especially when bathing and washing, I always feel very strange when there are these three things next to them, and the smell is not very good after washing." ”

Then Cao Yi rubbed the soap on his hands under the gaze of the three of them, and after rubbing out a foam, he cleaned the grease at once, and washed it in another basin of clean water, and wiped it well, smelled his hands, the taste was not bad, there was a good smell of flowers, in addition, there was a faint aroma of milk, but the smell of honey did not smell.

Then Cao Yi motioned to the three of them to clean it according to the action and process he had just demonstrated, and found that it could be cleaned quickly, and it was indeed very fragrant on their hands after washing.

The key is that this thing is easy to store, such a small piece, whether it is carried or transported is very convenient, if the mold is made a little more beautiful, like what lotus, peach, crescent moon and the like, and then carved on the surface of the pattern or poetry, make it more exquisite, it can definitely be sold at a good price.

After Red Sleeves and Wang Zhiyuan realized the effect of this soap, they and Cao Yi entered the house and began to discuss how to package and operate this soap in the later stage.
