Xu Qing tied skate shoes to his boots. The so-called skate is actually a piece of thick iron that can be sharpened quickly. The skate is set at the bottom of the board and can be used when tied to his feet. They made skates to check the situation on the lake, and now it has become one of their entertainment.

"Qing'er, wait for me for a moment. I'll hold you."

"It's OK. I'll take two steps myself."

Xu Qing put on his skates and walked cautiously to the ice. Just after two steps, he heard a bang. He turned his head and saw Li Changting fall.

Xu Qing:???

Li Changting coughed lightly, stood up and said calmly, "it's OK. I slipped."

Xu Qing shakes his feet and slides slowly on the ice. He gradually finds the feeling of skating in those years and goes steadily step by step.

"Bang!" There was a fall again behind him. Xu Qing looked back and saw Li Changting slide out several meters with a posture of falling to the ground.

Xu Qing resisted the impulse of laughing and went to help him: "can't you skate?"

Li Changting slightly embarrassed: "did not slip."

Xu Qing held his hands: "come on, I'll teach you. It's very simple."

On the other side, the beards were already competing with each other. A group of people quickly glided past Xu Qing and Li Changting and circled around the ice lake. Whoever got to the end first was the winner.

Little by little, Li Changting is like a baby learning to walk. He slowly finds his balance on the ice, but once he is too fast, he will fall down accidentally. When he falls down, Xu Qinggen can't hold him, so he can only follow him to the ground.

As Xu Qing taught him skills, he let go of his hand. After falling several times and being ridiculed several times by the beard beside him, Li Changting was able to stand firm and slide for a distance.

Experience is accumulated through repeated practice. Li Changting practiced alone for two hours in silence. In the end, he was able to skate well.

Xu Qing himself played with them, sweating.

A morning spent in happy skating, Xu Qing and Li Changting are going to leave, they had come to see, since there is no matter, there is no need to stay.

But just as they were about to leave, another group of people came to the village.

There are not many people who can find this place. At first, they saw a large group of men dragging wooden carts, which really scared the people in the stronghold. Later, when they saw some familiar faces, they found that they were acquaintances.

The other side was so cold along the way that he couldn't even speak quickly when he opened his mouth, and his mouth fell several times.

Beard quickly took people into the cave to keep warm.

After a long time, after these people recovered, they slowly explained their intention.

"I'm Xu Gao. We've seen him before." The first man said.

Beard nodded: "well, I know you. You are the Deputy General of General Zhao Jian. What's the matter with you coming to us?"

Bearded heart beat drum, the other side but drag several cart to come, should not be to ask for food? If he wants food, will he agree or not?

They don't have much grain in the stockade. They just have to survive the winter. If they take it out, it's not a small amount. Beard doesn't want to take it out.

But Thanks to Zhao Jian's help, they can't help them all the time. But now when Zhao Jian asks for their help, they don't agree. It's a bit too unkind.

Mustache was fighting between man and nature in his heart, with obvious worry on his face.

"We came from Xinghu to ask you a little help." Xu Gao probably saw his worry and said frankly, "it's not about food, it's about water."

"Water?" Everyone present was stunned.

Li Changting asked, "you don't have any water there?"

Xu Gao frowned: "it's frozen. You know what we're digging is an artificial lake. The water is from an underground river. But half a month ago, the river was frozen and the whole lake was frozen!"

"As you know, there are a lot of people over there, 250000 people. We have to use a lot of water every day. After the river freezes, we can only dig ice, but it's gone. The upper reaches of the river are frozen and can't pass. We don't even have ice now."

Li Changting nodded clearly: "so you are here to ask for ice?"

Xu Gao nodded: "yes, beard, your lake is so big and there are so few people. You can't use so much ice and water, so can you give us some? If we don't have any way, we're sorry to ask you..."

Beard patted him on the shoulder: "what's so embarrassing about that?! Isn't it ice? You just chisel it away. You don't have to be polite to such a trifle if it's too big! "

As soon as he heard that he didn't come to ask for food, he felt relieved. Water is a small matter. Anyway, they can't use up the lake. Why not help others.

Xu Gao said with a smile, "I knew that beard was loyal. Thank you."

Beard also said: "Hey, you take such a big risk to bring us salt, but you only charge some hard work. If I don't help you, who am I!Zhao Jian helps bearded cottage to bring salt. The freight charge means that he doesn't want more bearded salt.

Beard said with emotion: "the more difficult it is, the more we need to help each other."

Xu Gaoshen thought he nodded: "so I'm not bringing people to dig the ice. The ice is easy to take. I'll load five cars to go back to meet the emergency."

Beard: "it's a fine day today. You have a rest. In the afternoon, I'll take my brother to help you dig the ice. Anyway, we are idle."

Xu Gao nodded and asked, "is there any water under your lake?"

If there's no water, or if it's frozen through, the ice will be used a little less.

"There's water." The beard affirmed, "you'll know when you chisel it. The lake is deep. If it's frozen through, how can the fish under me live?"

Xu Gao laughs: "that's good."

Xu Qing also said: "it won't be completely frozen. Don't worry, this is a natural lake. The thickest ice layer can't be more than two meters. Star lake is an artificial lake. It will be completely frozen only when water level drops too much due to frequent water use and climate change. But the lake here is very deep, so don't worry."

After listening to Xu Qing's analysis, beard and Xu Gao nodded in agreement.

Although the lake here won't freeze through, it's hard to say that the tributaries flowing to Changxi village. Originally, the underground river was so deep that the temperature would not change with the outside world.

However, Xu Qing did not think that the river in his village would be cut off or even frozen.

Because of their sudden arrival, Xu Qing and Li Changting stayed here for another day.

Ice digging is a dangerous thing. If you are not careful, you may fall into the water. So everyone tied a long rope around his waist, and the other end of the rope was tied to a big tree. If someone accidentally fell into the water, you can quickly pull the rope up.
