Liu Jinyu came once in the middle, said a few words to her, and left in a hurry.

Tranquility replied to him in a daze, but she had forgotten what she had said, and she had been so confused for two days, the fever subsided, and she got used to the pain, and finally felt like she was alive, and her spirit improved.

Then she noticed the muffled sound of shells and bullets in the distance, and the occasional buzz of bombers in the sky overhead.

The spectre of war hangs over everyone's mind.

Tranquility's heart sank, and she was unusually worried.

But she couldn't do anything.

Fortunately, two days later, Mingqing came to accompany her and told her about the progress outside.

Mingqing was wearing men's clothes this time, with a coat and a hat, and her hair was all coiled in, which was more handsome, but also more nervous.

She came in with the cold outside, and there were small snowflakes on her shoulders and hat, which were turned into droplets by the heat of the room.

Tranquility realized that it was snowing outside.

"How's it going out there? You weren't in danger when you came, were you? ”

She has been in good health for the past few days, but she has been lying in bed all the time, basically unable to move, very boring.

Mingqing put down her clothes and hat and walked over, looking at her face with concern, and her face softened slightly.

"The situation has become more and more tense in the past few days, but at present, it is still Liu Dashuai who has the upper hand, the British troops are all stationed on the warships on the sea, and when the weather is cold, the consumption on their side will be large, and the supply will also be affected by the weather and it is not good to send it over, on the contrary, we have hoarded a large amount of food in the city before, and the supply is sufficient, and when the weather is colder in a few days, it is best if the sea is frozen, they will be trapped on it and will not be able to go anywhere, and they can only be captured when the time comes."

Mingqing was afraid that she would be worried, and what she said was all positive, but Ning Ning thought that if it was really so easy, Liu Jinyu would not have come back for so long.

Besides, it's hard to do such a thing as freezing on the sea.

It's not an ordinary lake or river, Jinling City belongs to the south, and the temperature is not particularly low even in winter, so how can it freeze?

If before, when she practiced the Ice Condensation Palm to the ninth level, she could have quietly lurked over and froze the water around the boat, but now, she has only practiced the Ice Condensation Palm to the first level, and she really can't do it.

If only there were chemicals that can freeze water quickly.

A flash of inspiration flashed through Tranquility's mind, if memory serves, that ammonium salt will take away a lot of heat when dissolved in water, and if the amount is large enough or the amount of water is small enough, the water can freeze in an instant.

But she didn't know where to get it, and she was a little worried that if she said it, others wouldn't understand what she was talking about.

She asked Mingqing, and after Mingqing heard it, she looked at her in surprise.

"When you say that, I remember, I also studied a little bit of chemistry when I was abroad, and this seems to be knowledge from the West, right? How do you know. ”

Tranquility snorted in confusion.

"Really? I think I saw it in some book, you know that I am more studious, and my memory is good, and I thought it was amazing at the time, so I remembered it. ”

She was vague, then re-emphasized, and asked Mingqing if this was okay?

Mingqing also believed her words, others can't see this kind of book, can't Liu Jinyu get it?
