Gu Huaiwei pulled the cart and wiped the thin layer of sweat from her forehead.

On it were placed a five-liter oxygen cylinder and two five-kilogram buckets of mineral water.

Xiao Youqi opened the door and saw these things. A gleam of light flashed in his gray eyes: "Please come in, Miss Gu."

He helped Gu Huaiwei pull the cart into the room.

"Here are five-liter oxygen tanks and ten kilograms of fresh water."

"You have to ensure that these things won't disappear once you take them out." Xiao Youqi still clearly remembered the last time he smoked the free air in the hotel and almost suffocated to death when he went out.

He didn't want to experience again the pain of having difficulty breathing, his lungs squeezed by lack of air, and every cell in his body lacking oxygen.

Gu Huaiwei glanced at him and said, "Of course, paid things are more reliable than free ones."

Xiao Youqi caressed the iron can of the oxygen cylinder with his hand, saying, "If these things can be used normally in the outside world, I will want more."

"Sure, but I'm going to raise the price."

Xiao Youqi frowned: "How much is the increase?"

Mineral water costs eight yuan per barrel, and the shipping cost is a little more expensive.

An oxygen cylinder costs 2,000 yuan each, which is a relatively high cost price.

“Mineral water costs one gold coin per bucket, and one bucket is five liters.

Oxygen cylinders are ten gold coins each..."

"Fresh water is reasonably priced, but oxygen is too expensive." Xiao Youqi interrupted her, "The oxygen in the dungeon is only one gold coin a can. With a ventilator, one can is enough for seven days."

"Well, so I mainly sell water here." In order to reduce costs and maximize profits, Gu Huaiwei decided to sell oxygen cylinders only to people who need short-term emergencies.

As for those who have enough oxygen to last back to the dungeon, they don’t need to buy from her.

Xiao Youqi didn't want to give up the oxygen business, so he persuaded her: "Your air is free here, why don't you lower the price a bit? That way, we can both make money."

Gu Huaiwei flatly refused: "No, I have to consider the purchase cost."

Xiao Youqi didn't know what to say.

"I need ten more barrels of fresh water. I'll pay you in three days. Please prepare the supplies first."

"Can."

"Miss Gu..." Xiao Youqi hesitated to speak. He shouldn't meddle in other people's business, but for the sake of the deal, he still gently reminded her, "It's very windy and dusty outside. Be careful and don't go out alone."

"Are you worried about me?" Gu Huaiwei smiled faintly, "Even if you say something nice, I won't give you a discount."

Xiao Youqi couldn't see through her.

It is said that the eyes are the windows to the soul.

But the girl in front of him was wearing thick glasses and her sparse bangs were a little long. He could not see her eyes, nor could he understand her inner thoughts.

After Gu Huaiwei finished discussing business, she did not leave immediately. Instead, she stood at the end of the corridor and looked at Room 301 silently.

Ten minutes later.

Room 301 was quietly opened a crack.

The pink-haired girl had two small pigtails on her head. She stuck her head out and looked at Gu Huaiwei who had not left yet, unable to dodge.

Gu Huaiwei winked at her and signaled her to go downstairs.

Return to the first floor lobby.

Qian Duoduo followed with some hesitation.

"How did you know I was eavesdropping?" Qian Duoduo took off his disguise, the smile on his face disappeared, and he stared at Gu Huaiwei with a fierce look.

"intuition."

Gu Huaiwei's five senses have been sharp recently.

On the surface, Qian Duoduo is a young girl.

In fact, Qian Duoduo was not wearing protective clothing. Gu Huaiwei saw the rough lines on the back of her hands, and the skin below her neck was like a weathered tree. Except for the face where time had stopped, the rest of her body was gradually withering and dying.

"Don't you want to discuss business with me?" Gu Huaiwei offered an olive branch. "Instead of thinking about selling me to that Black Spiral Research Institute, why not start from reality and cooperate with me?"

"How do you know about the Black Spiral Research Institute?!"

Qian Duoduo instantly drew his gun and pointed it at Gu Huaiwei.

The hotel alarm was triggered.

Countless infrared sniper points are aimed at Qian Duoduo.

Qian Duoduo's whole body was stiff.

A drop of cold sweat slid down her forehead.

Can't beat him.

Before she could even pull the trigger, the hotel security robots would have shot her to pieces.

She suddenly remembered Xiao Youqi's warning.

It's been too long since I suffered any loss, so I'm a bit blindly confident.

The hotel's defenses were even stronger than she had seen!

Gu Huaiwei leaned leisurely against the front desk, folding her arms: "It's not polite to point a gun at someone."

"I..." Qian Duoduo didn't want to push the situation to an extreme. Seeing that she couldn't win, she silently put the gun away and shamelessly played dumb. "How about we talk business?"

"Of course, but you have to show me your sincerity, otherwise I won't be able to trust you."

Special environment creates special people.

Gu Huaiwei quite likes the residents of this world.

Ambitious, but also aware of the times.

If you can win, you will just want to tear your opponent into pieces and eat them without even spitting out a bone.

If they can't win, they will just act like a grandson and fight for other interests.

The security in the hotel disappeared.

Qian Duoduo regretted his impulsiveness and missed a good opportunity to buy water from Gu Huaiwei.

She raised her head and said, "I will prove that I am more useful than that kid Aqi."

After saying that, she turned and ran upstairs.

In the afternoon, Lin She came back exhausted after distributing all the flyers.

Five minutes later, six customers came in.

"Welcome!"

Gu Huaiwei immediately stood up to greet the guest.

Great, we finally have guests.

Linshe's work efficiency is truly commendable.

However, before Gu Huaiwei could be happy for long, a scene she had never expected appeared before her.

The tall man kicked the man whose protective suit was the most torn on the knee.

The man howled like a cow about to be slaughtered, kneeling heavily on the floor with his hands supporting the ground.

The remaining people stepped forward and stripped the protective suit off the person who fell to the ground.

"No! Ahhhh! I don't want to die! I don't want to die!" The man screamed as his mask was mercilessly taken off.

After coming into contact with the dust on the protective suit, he suffered from ulcers all over his body. Even so, he still covered his mouth tightly until his face turned the color of pig liver, and he refused to breathe.

The person next to him pulled his hands down and twisted them behind his back.

The man couldn't bear the pain any longer.

His face was covered with tears and snot, and he was gasping for air with his mouth open.

Once, twice...

Fresh air was poured in in big gulps, flowing down the trachea into the lungs, without any burning or corrosive pain.

He was overjoyed, crying and laughing, dancing with joy as he spoke to the people around him: "I'm not dead! Hahaha! The air here is really breathable... No need for a ventilator, no need for protective clothing, I'm not dead! I'm still alive!"

"Bang!"

Accompanied by a burst of gunfire, the man fell straight to the ground before the joyful expression on his face faded.

Blood flowed from the small bullet hole in the head, staining the hall floor.

Murder!

Gu Huaiwei's eyes darkened.
