Qi Xiao believes that heating is not the only way to melt ice, there are other methods.
For example, use table salt appropriately.
Under the action of salt, ice and snow will slowly melt into water. He has verified this result many times in the laboratory and is guaranteed to be 100% effective.
The purpose of studying this method is mainly to simulate deicing projects on roads to provide academic theoretical support.
However, a theory is still a theory and may not be applicable in reality.
Take the current Dafeng as an example. The purchase and sale of salt are strictly controlled by the government. Therefore, the cost of salt is not generally high. Using it to de-ice roads is definitely a waste of money!
Therefore, this kind of knowledge only exists at the academic level and has no practical value at all.
But now, Qi Xiaotong wanted to move here and give it a try.
So, she was so moved that she decided not to act.
First of all, she had to solve the problem of the source of salt. This was not a problem for her, and it was easy for her to do.
She took advantage of the enemy's lack of attention to steal their army's salt, and then secretly sprinkled it at a key point on the fortification.
If one time is not enough, we will come a few more times. Anyway, we have to use up their salt store.
While I was busy, I suddenly saw Hong Tao's troops coming to attack the city.
Due to the situation, it is not appropriate for her to appear in public, otherwise all her efforts will be wasted.
In this way, she secretly witnessed the entire process of his shelling, burning, and forcible attack.
In order to prevent unnecessary casualties as soon as possible, she could only try her best to speed up her actions in order to shorten the time.
Finally, it's done.
Just when she stopped, she saw that Hong Tao was in danger. In desperation, she hurried over and reached out to rescue him.
However, it was still a step too late, and he was unfortunately hit by an arrow.
However, the good thing among the misfortunes is that this encounter was a near miss, otherwise, she would regret it for the rest of her life.
Then, why didn’t Xiaotong take action from the beginning?
From a military perspective, that is not allowed.
No matter how big or small things are, justice should be put first, and the love of children should be put second.
Therefore, Qi Xiaotong's approach was not only heartily understood by Hong Tao, but also received repeated praise from him.
"Miss, does your trick of spreading salt to melt ice work?"
"Whether it works or not, I don't know. However, my brother's knowledge in science and engineering is very profound, which is definitely not comparable to that of an ordinary bachelor. He said that this method can work, and it should be close to it."
"You mean...this method is not particularly reliable?"
"Whether it's reliable or not, we'll find out later."
That's true!
It won't be long before we can see how effective it is.
Thinking of this, Hong Tao hurriedly took out his telescope and looked towards the fortress where Xiaotong was blocking him.
Faintly, there seemed to be liquid ice water slowly flowing out. If you didn't distinguish carefully, it would be difficult to find this slight clue.
Is it difficult to detect?
In fact it is.
Although the ice there has melted, it is covered by the white snow on top. It is for this reason that the Tatar army can pay attention.
Of course, this is also related to their bravery and lack of strategy. Once they lose the analysis of counselors, they become blind like primitive people.
"Don't tell me, the ice actually melted there!"
"Really? Show me quickly."
"Um……"
From the perspective of combat division of labor, the role of the vanguard is not to destroy many enemies, but to clear obstacles for the large forces behind them.
The obstacle here refers to it in general.
For example, traps, roadblocks, ambushes, etc. on the way all need to be cleared by the vanguard one by one. If you encounter an encounter, you must have the courage to boost your morale.
Therefore, how to destroy the enemy's newly built ice and snow city wall has become the top priority of today's mission.
However, now, there are loopholes in the enemy's defense. From this perspective, the mission has been completed.
Next, there are two options to choose from.
First, start the siege. Second, wait to rendezvous with the large army.
Hong Tao, who was eager to make meritorious deeds, decisively chose the former. However, he was strongly opposed by Xiaotong.
"It is not wise to use small things to make big things."
"Then... we can't just wait?"
"If you don't want to wait, why not do something more meaningful than killing enemies?"
"Well……"
Hong Tao really couldn't understand. What else could be more meaningful than killing the enemy?
Seeing Qi Xiaotong giggling there, he quickly made a very humble request for advice.
"Miss, have you thought of some wonderful idea?"
"You guessed it right! However, I won't tell you unless you can ask me."
What?
Do you want me, a grown man, to beg you?
Then...of course no problem!
Hong Tao first glanced at the soldiers not far away, and then he cupped his hands in a cryptic manner and said: "I am sorry that Tao is stupid, but I hope the eldest lady can give me some advice."
"Well, that's pretty much it!" Qi Xiaotong smiled politely and said: "Since you are so good at talking, I will tell you about another piece of news I found!"
Hong Tao's face straightened when he heard this and asked: "What's the news?"
“It’s about the terrain!”
"terrain?"
Xiaotong nodded and said in detail: "The Tatars are currently occupying a place with their backs to the mountains. Although such a location is conducive to defense, it also puts them in a situation with no way out. Once they are defeated, they will
The only option is to flee to the mountains and then find other ways out to survive. But the so-called way out is only a narrow valley about ten feet wide..."
At this point, she stopped talking and looked at him with a smile.
Hong Tao tasted it and was suddenly enlightened.
His eyes flashed and he asked: "The eldest lady, do you want me to block this escape route before the war starts?"
Xiaotong couldn't help but praise and said: "You are getting smarter and smarter, you can guess right!"
Hong Tao, who was praised, smiled happily, but the next second, his expression became embarrassed again.
Blocking the valley is a time-consuming project, but it can't be done with just a few clicks.
Even if there are enough manpower, corresponding building materials will still need to be transported there. But now in the ice and snow, how easy is it to transport materials?
"I said, why don't you try and treat the other person the way he wants?"
"Oh? How do you say this?"
"The Tatars can turn water into ice and build a city in a moment, why can't you? When you get to the valley area, you can melt the snow into water and mix it with sand and gravel to build the high walls you need. This method uses local materials and does not
No transportation required."
This method is wonderful!
Hong Tao couldn't help but clapped his hands and screamed after hearing this.
At the same time, he was also thinking: Why didn't he think of such a simple method?
