Chapter 556: Ice

This was a dusty, ordinary-looking exhaust fan of the subway's air conditioner.

The moment he saw this thing, a chain of thought popped up in his mind — exhaust fan, air conditioner, low temperature, ice!

Ice!

His eyes were bright. In this ruined city, all the things from the old era had been corroded or destroyed by the weather. It was almost impossible to find a bag that could seal the smell of Haisha's blood. But there was one thing that could do this, ice!

"It's the black snow season now. The temperature is low, so it's easy to get ice..." Dean's eyes flashed slightly, looking out of the subway as a gust of cold wind blew in from the broken window. Haze was slowly filling the sky. It was estimated that it would snow heavily soon.

However, he had no intention of waiting for the snow. Leaving his fate to the God's arrangement had never been his first choice. Moreover, the black snow contained too much nuclear dust. Not to mention the nuclear radiation, the black snow was like loose sand, could not be mixed with each other like a normal snow.

"I can only make the ice myself. I could use the low temperature of the black snow to freeze the water if it snows now, but looking at the weather, the snow would probably start falling tomorrow or the day after tomorrow. I can't wait that long." Dean's eyes swept around the collapsed walls outside the subway and did not find what he wanted. It should be because the humidity here was not low enough.

He glanced at Haisha that was lying down on the seat, and took a deep breath, saying, "I hope your luck won't be so bad."

No longer hesitating, he jumped out of the window and flew away.

He flew out of the collapsed subway and soared high in the sky, turning his head around looking at the surrounding buildings. He set his eyes on a collapsed building near the subway. The building was covered with a thick layer of moss and entwined with large vines.

Dean's eyes were bright. He quickly landed while still paying close attention to the surroundings near the subway. Once a monster appeared, he would immediately rush back to defend.

"It's here!" He landed outside the building, and when he pushed the vines aside, he immediately saw a crust of snow-white crystalline stones at the corner of the building, sticking to the wall like frost. His eyes were shining, and he quickly took the crystalline stones off and loaded it into his backpack, then collected the remaining crystalline stones that existed in the building.

"Lucky," Dean said in his heart. He did not expect to find so much potassium nitrate so easily. Potassium nitrate usually formed naturally in the shady corners of caves.

This was one of the ingredients for making gunpowder. With sulfur, it could be made into powerful gunpowders. But what he wanted was its powerful heat absorption characteristic!

It was an excellent material for fast ice making!

He soon collected all of the potassium nitrate in the building, filling his backpack full. Due to the collapse angle of the building, the corners inside the building were not exposed to the sun for years. This was why so much potassium nitrate would form.

The reason why he had the thought of making the ice himself was that he had seen the potassium nitrate growing on the ruined buildings' walls many times before.

Whoosh!

He quickly returned to the subway and jumped into the broken window. He sighed in his heart when he saw that Haisha was still in a coma. He knew that she was suffering, and her body was slowly eroded by the poison.

He raised his hand, reaching out for a rusty metal sheet that was sticking out of the carriage's body and tore it away. He put the potassium nitrate on top of the metal sheet and rolled the metal sheet into a ball. This tough metal was like a paper in his hand and could be kneaded at his will. Soon, the metal sheet became an airtight metal ball, wrapping the potassium nitrate in.

He stuffed the metal ball into his backpack, then picked Haisha up with both hands and quickly rushed out of the subway.

Although the ice-making material had been found, the smell of her blood had already permeated throughout this place. They had to get away from here and find a new hiding place.

Moreover, he had to find one that was close to a water source.

When he was searching for a hiding place for the Shadow Hunter eggs, he flew over a lot of places and saw several places where a water source was present. He immediately went to the nearest place.

Rumble!

Flying high in the sky, Dean heard rumbling sounds from the ground. He saw several three meters tall, bulky, wolf-like monsters running on the street, and their direction was the subway he had just left.

He secretly rejoiced in his heart. Fortunately, it did not take much time to find the potassium nitrate; otherwise, Haisha would be in danger.

These monsters were not aware that Dean was flying in the sky when they were passing below him.

After seven or eight minutes, Dean finally arrived at the place near a water source. This was a plaza, and the pavements had completely collapsed. There was a large hole at the bottom of the plaza. The hole had accumulated years of rain and became a big pool.

Dean's thermal vision saw that there were only finger-thick, red heat sources in the pool. It should be the insects that fell from the monsters' bodies while they were drinking from the pool, then grew through the radiation inside the pool. He shrank his pupils, and the pool in his eyes seemed to become semi-transparent. He looked into the pool carefully and found an underground drainage channel.

He looked at the direction leading to the channel and did not see any heat source. No longer hesitating, he covered Haisha's nose and mouth with one hand and held her body with his other one hand, then dove down headfirst into the pool, making the water splash high.

He rushed at full speed while holding Haisha closely. His body was straight, his legs were kicking, and his wings were not retracted, still fluttering hard. His wings were not feathers, but a kind of hardened skin that resembled hard-shell wings. It could be used as a booster in the water.

Whoosh!

His speed was so fast that even ordinary fish was slower than him.

The small heat sources that were scattered all over the pool seemed to feel his movement and quickly swam in his direction. But their speeds were slower and could not catch up with his speed. Soon, the heat sources behind him gathered together and followed behind him, seemed to be sucking the blood that was seeping from Haisha's wound and diffused along the way.

Dean quickly entered the underground drainage channel and swam along the channel. His pupils were always in the shrinking state, making the things in front of him semi-transparent, so he could see the situation ahead.

He swam fast, passing through several junctions, and finally arrived at a cave-like dark channel.

Splash!

Still holding Haisha closely, he leaped out of the water and landed ashore.
