This is an exhaust fan on a subway air conditioner, full of dust, ordinary and unremarkable.
The moment he saw this thing, Du Dian immediately thought of several things, exhaust fan, air conditioner, air conditioner, low temperature, ice cubes! That's right, ice cubes!
His eyes are bright. In this ruined city in the wilderness, all the things of the old era are either rusted and rotted or weathered and destroyed. He wants to find an airtight bag that can seal the smell of blood on Hailisha. It is almost impossible, but there is one thing that can do it, and that is ice!
"It's the black snow season now, the temperature is low, and it's easy to get ice cubes..." Du Dian's eyes flickered slightly, looking outside the subway car, gusts of cold wind blowing in from the broken windows, and he could vaguely see the hazy sky outside, probably Soon there will be a heavy snowfall.
However, he has no intention of waiting for this snow. He has never considered it as his first choice to leave his fate to God to arrange. Moreover, the falling black snow contains too much nuclear dust, which contains nuclear dust. Not to mention the radiation, due to nuclear fallout, the black snow cannot accumulate into ice like ordinary white snow, but will be like loose sand, which cannot be kneaded.
"I can only make ice myself. If it snows now, I can use the low temperature of the black snow to freeze the water into ice, but judging by the weather, even if it snows, it may be tomorrow or the day after tomorrow. I can't wait that long. "Du Dian glanced around the collapsed wall outside the subway, but didn't find what he wanted, probably because the humidity here is not heavy enough.
He glanced at Hailisa who was lying flat on the chair, took a deep breath, and said, "I hope your luck won't be so bad." After saying that, he didn't hesitate anymore, and quickly got out of the window and flew over out.
He quickly came to the outside of the collapsed subway, flapped his wings, took off, turned his head to look at the surrounding buildings, and suddenly saw a collapsed building near the collapsed subway, with large vines wrapped around the building, covered with thick A layer of moss.
Du Dian's eyes were slightly bright, and he landed quickly, while keeping some attention on the vicinity of the subway. Once a monster appeared, he immediately rushed back to block it.
"Yes!" He landed outside the building, and when he pushed aside a vine, he suddenly saw a cluster of snow-white granular stones at the corner where the building was in contact with the ground, adsorbing on the building like frost. His eyes lit up, he quickly snapped it off, threw it into his backpack, and then quickly collected along the corner of the wall, taking out all the white granular stones adsorbed on the building.
"Good luck." Du Dian thought to himself, he didn't expect to find so much saltpeter so easily.
This substance is one of the ingredients for making gunpowder. Combined with sulfur, it can be made into powerful gunpowder. The principle of this is its powerful heat-absorbing properties!
This saltpeter generally grows in shady corners, caves and other places. It is a natural ore and an excellent material for quick ice making!
Soon, Du Dian collected a full backpack, holding a handful of saltpeter in his hand, and took all the saltpeter under the collapsed and overturned building. Due to the rollover angle of the building, the corner of the wall is not exposed to sunlight all year round. , This is how so much saltpeter grows.
The reason why Du Dian thought of making ice by himself was because in this wilderness, he had seen these saltpetres growing on the walls of the ruins many times.
Whoosh!
His figure quickly returned to the front of the subway car, and he dived into it. He glanced at Hai Lisha who was still in a coma, and knew that her body was suffering from severe poisonous erosion. Rusty metal skin, put a handful of saltpetre in his hand into it and roll it into a ball. This tough iron skin is like paper in his hand, knead it at will, and soon knead it into a completely sealed metal ball, wrapped in With saltpeter.
He stuffed the object into his backpack and clamped it, then picked up Hailisa with both hands, and quickly rushed out of the subway car.
Although the ice-making material has been found, there is already too much blood smell escaping from this place, and it must be far away as soon as possible. It is not suitable as a hiding place.
Also, he had to find a place near a water source.
When he took Shadow Hunter Eggy to find a hiding place, he flew over many places, and several of them had water sources. He immediately rushed to the nearest water source hiding place.
Whoosh!
When flying high in the sky, Du Dian suddenly noticed that there was a rumbling sound from the ground, but he saw several monsters with a height of nearly three meters, a strong body, and a figure like a wolf rushing rapidly on the street, and their direction was the same as his previous one. Hidden subway directions.
He secretly rejoiced that it didn't take much time to find the saltpeter, otherwise Hailisha would be in danger.
These few monsters hunting in groups did not notice Du Dian passing by in the sky, and the two quickly staggered and drove away from each other.
After seven or eight minutes, Du Dian finally arrived at this place with sufficient water source. This is a collapsed square. a large pool.
Du Dian's thermal vision saw that there were only some finger-thick red heat sources in the sunken square pool, which should be water bugs grown by radiation from germs that fell into the water from the monsters that drank water over the years. He stared at it. After taking a second look, the pupils shrank slightly, and the pool in his sight seemed to become much more transparent, and an underground drainage channel was seen under the pool.
He looked in the direction of the aisle, and saw no reaction from the heat source. He stopped hesitating immediately, covered Hailisha's nose and mouth with one hand, and hugged her body tightly with the other. He swooped down quickly and crashed into the pool in the square. .
With a splash, high water waves splashed, and he rushed into the water at full speed with Hailisha in his arms. His legs swung, his wings were not retracted, but were still flapping vigorously. His wings were not feathers, but a layer of skin The wings, which are hardened like a hard shell, can also be used as a booster in water.
Whoosh!
His body swims straight and fast, even ordinary fish may not have his current swimming speed.
The small heat sources scattered everywhere in the pool seemed to sense movement, and quickly swam towards Du Dian, but the speed was relatively slow, failing to catch up with Du Dian, just following the water he swam through, and soon gathered in groups , chasing after Du Dian passed by the water, as if sucking the blood diluted from Hai Lisha's wound along the way.
Du Dian quickly swam to an underground drainage channel connected to the pool, and swam along the channel. His pupils remained in a miniature state, so the things in front of him became somewhat transparent, and he could see the scene in front of the channel.
He swam quickly, rounded the corners of several passages, and suddenly saw a dark passage similar to a cave.
With a crash, he jumped out of the water with Hai Lisha in his arms, and landed on the shore by the water.
