That is indeed a big flaw.
At this time, batteries are limited, and Qiao Xuejun has stockpiled a lot of No. 5 batteries. This type of alkaline battery has a shelf life of more than ten years, but it is disposable and will be gone once used up.
According to the consumption rate Zhao Yun described, if she uses 6 batteries in an hour, the batteries she has stockpiled will only be enough for three to five days.
In comparison, it is more cost-effective to use it to replace batteries for radios and flashlights.
Qiao Xuejun picked up the wristband on the table.
This wristband has not yet been equipped with any electronic components. It is just a simple wristband, a little bigger than the one she is wearing now, and it looks like it is made from a glove.
Zhao Yun said, "These gloves are a pair that my brother specially collected. They are called Winter Scale Armor. It took a lot of effort to buy them. Now he can tear them apart just like that."
After a brief sigh, he went back to talking about technology: "Just put a PT heater in a wristband and connect it to a thermostat. But the thermostat and heater are a bit large and not very portable."
Qiao Xuejun: "No need to bring it."
Zhao Yun looked at Qiao Xuejun: "No need to carry it? My brother said it would be best if it could be used anytime, anywhere."
Qiao Xuejun's eyebrows softened. "No, just use it before going to bed tonight. It only takes 20 minutes. No need to carry it around."
Zhao Xian has been giving her hot compresses every night these past few days. He has tried a kettle of hot water and a hot towel.
Hot towels are not very effective. They are troublesome and they lose heat quickly and become cold again. You have to change them frequently and you may accidentally get your cuffs wet.
It is difficult to control the temperature of a kettle, and it is often too hot.
Perhaps because of this, Zhao Xian customized this controllable electric heating wrist band.
Qiao Xuejun didn’t really take the matter of her wrist too seriously, but Zhao Xian always cared about it.
It's almost become a knot in my heart.
Zhao Yun suddenly realized: "The expert my brother was talking about is you, Teacher Qiao?"
Before Qiao Xuejun could answer, Zhao Yun suddenly realized, "I was wondering why you took off all the gloves."
Qiao Xuejun raised an eyebrow: "Just to take off a pair of gloves, isn't it worth it for an expert like me to contribute a pair of gloves?"
Zhao Yun said without hesitation: "That's totally worth it!"
Zhao Yun said, "If it doesn't need to be portable, the technical difficulties will be reduced. After all, if we're protecting the components of the sled, they don't actually need to be portable, because the components can be fixed to the vehicle."
Qiao Xuejun: "Well, report to your brother again."
Zhao Yun: "Okay."
After getting a rough understanding of the progress of the sled, Qiao Xuejun left again. She returned to the shelter in the afternoon. Before leaving, she specifically found the horse herder and told him to pay special attention to the pregnant mares and to contact her at any time via walkie-talkie if there was anything abnormal.
There are special patrol guards around the experimental fields, and they all have walkie-talkies.
After making the arrangements, Qiao Xuejun returned to her shelter. She would try to come back whenever she was free these days to take care of the breeding farm and plantation.
The cotton is growing normally and has already bloomed in large areas.
The same goes for the farm. Rudyard Kipling chickens are also being bred recently. Her goal is to expand further and hope that eggs can be supplied on a large scale like spinach.
You don't have to eat it every day, once every three days is good too.
Because she came here almost every day and the work was not much, it took her six hours in the afternoon to finish her work here and return to Hongmei Mountain.
Since the Engineering Department started working on the sled, the road between the shelter and the base has been built.
It is called a road, but it is actually very simple. There are some tree stakes in the middle to mark the location. It is the flattest and easiest road to walk on.
Walking back to Hongmei Mountain along that road, Qiao Xuejun looked around and saw that everyone who was supposed to be off work had already left, there was no one in the greenhouse, and the horses had all returned to the stable.
Qiao Xuejun went to the small, isolated room in the stable to check on the condition of the pregnant mare.
Changes in the reproductive area are more obvious, and the due date is imminent.
She gave the mare more feed.
The feed is now richer. In addition to the original straw, forage and corn kernels, there is also pumpkin seed meal.
The richer the nutrition, the better the mare's physique and the smoother the pregnancy and delivery.
After finishing her work, she returned to the base, washed up, and then returned to the small igloo next to the stable. She sat in the igloo, lit the blue oil lamp, took out her notebook and began to record data.
I was too busy today and didn’t have time to record the data.
She hadn't been doing this for a while when she heard some movement outside the door.
She didn't need to look up; she knew it was Zhao Xian just by the sound of his footsteps.
Zhao Xian entered the snow house and patted the snow particles off his body.
"Are you still busy?" he asked Qiao Xuejun.
Qiao Xuejun: "It's almost over. We just need one last set of data."
Zhao Xian was busy with something nearby, and it took Qiao Xuejun a while to finish the data in her hands.
She put away her notebook and looked at Zhao Xian.
Zhao Xian got a small portable stove from somewhere. It was smaller than the one Qiao Xuejun had seen before, about the size of a basketball.
There was water boiling on the stove, and a small kettle on top of it.
She came over and squatted beside Zhao Xian, looking at the stove. She reached out to warm herself by the fire, feeling the warmth of the stove. "It's quite warm. I hope it won't collapse the igloo."
She could feel that the temperature of the igloo had risen a little because of the stove.
Zhao Xian said, "It's minus 40 degrees Celsius now. It won't collapse."
The melting speed is not as fast as the solidification speed.
It's like the saying goes, the warmer, the stronger.
Zhao Xian took the kettle down, picked up a towel from the side, and wrapped the kettle tightly.
After holding it for a while, he felt the temperature of the towel and found it was neither hot nor cold. He stretched out his hand and said, "Give me your hand."
Qiao Xuejun extended her hand to him.
Zhao Xian held her wrist, removed the wristband first, and then put the kettle and hot towel over her.
