After time travel, the system allowed me to keep learning

Gong Hetong immediately knew what Gong Ruixue wanted to do, said "wait" and went out.

Ling Jing was as curious as Xiao Yu'er, weren't they talking about Bing? Why do you need saltpeter all of a sudden?

"What do you want saltpeter for?" Ling Jing asked.

Gong Ruixue raised her eyebrows: "You'll know in a moment! Xiaoyu'er, help me find a big wooden basin and a small iron basin. Fill both basins with water. I'll show you something fun later. of!"

"Okay, I'll go right away!" Xiao Yu'er responded and ran away.

"Tell me, why did Qi Huxu allow you to accompany Miss Xia?" Gong Ruixue looked at Ling Jing who was sitting aside.

Ling Jing looked at Gong Ruixue. She was probably the only one who dared to call that person a fox, but it was quite appropriate. But Ling Jing didn't quite understand the benefits she mentioned: "What benefits?"

When Gong Ruixue saw Ling Jing acting like this, it was obvious that she had been sold by Qi Huhu and had to count the money for him.

"He asked you to take care of such a difficult person, and you didn't ask him for any benefits?"

Ling Jing shook his head. He agreed to take care of Xia Jingxue because Qi Xinghai told him that Xia Jingxue was his cousin's daughter. The most important thing is that her cousin is already on her way and will arrive in two days. She just needs to stabilize her mood before Xia Jingxue's father comes.

Gong Ruixue was furious when she saw Ling Jing acting like this. After that, she had to go to Qi Xinghai to get the benefits back.

"By the way, while there is no one around now, I want to tell you a secret. Come here."

Gong Ruixue waved to Ling Jing mysteriously, and Ling Jing squatted beside Gong Ruixue and put her ear close.

Gong Ruixue blocked it with one hand and lowered her voice to tell him that the man in red robe she saw during the sacrifice was the one who originally chased Ling Jing.

Ling Jing frowned: "Are you sure?"

Gong Ruixue nodded: "His voice is very distinctive. I am sensitive to sounds. Even if he speaks with a high voice, it is impossible to escape my ears. In addition, the black-robed man next to him has a killing method, so I feel very similar to when I rescued you. But I didn’t come into contact with the body, so I can’t be sure that it is.”

Ling Jing was deep in thought, but Gong Ruixue didn't interrupt his thoughts again.

If you can't help but talk about it, you were talking about Qi Xinghai just now. Now Gong Hetong, who came back with a few bags of saltpeter, was followed by a familiar wheelchair.

"Why are you here?" Gong Ruixue now saw that Qi Xinghai's nose was not a nose or an eye.

Qi Xinghai originally heard that Gong Ruixue was injured, and felt inexplicably anxious, so he followed Gong He. But now looking at the way Gong Ruixue looks at her, it's obviously very good.

"I heard that my exclusive doctor was injured, so I came here quickly to see her. After all, the doctor who costs me five hundred taels a month, I have to ensure that she can continue to serve me."

Qi Xinghai confirmed that Gong Ruixue was fine, and then he relaxed and teased Gong Ruixue.

When Gong Ruixue heard this, she was furious.

Gong Ruixue put her hands on her hips and said aggressively to Qi Xinghai: "Isn't it because of you that I got injured? You still have the nerve to say it, but I can tell you, this is called a work-related injury. As the main person in charge, you need to compensate me for the loss!"

Qi Xinghai raised his eyebrows: "Oh? I haven't even been out to Zhuangzi, how can it be because of me?"

"You hired my Ling Xiaojing to take care of Xia Jingxue, and you haven't paid him hard work. And I was injured by Xia Jingxue. As a client, you need to be responsible for her actions. Therefore, my compensation The total employment fee from Ling Xiaojing is one hundred taels, Mr. Qi, please settle the account as soon as possible."

Gong Ruixue stretched out her hand towards Qi Xinghai and rubbed her index finger and thumb.

Gong Hetong approached Gong Ruixue and said, "Daughter, this can't be called a work-related injury, right? Besides, your hundred taels are a bit suspected of blackmailing someone."

"Hiss, he doesn't understand. Besides, what I do is called robbing the rich and giving to the poor. I rob his rich and give to my poor. Now I can cheat as hard as I can, but when he can stand up and walk, he will be beaten if he cheats again. "

Gong Ruixue also moved closer to Gong Hetong. The father and daughter were biting their ears thinking that no one else could hear. However, for a martial arts practitioner with internal strength, the volume was not much different from talking normally.

Qi Xinghai showed a doting smile: "You are right, I will ask Mincai to send you the money tomorrow to calm your shock."

Then Qi Xinghai glanced at Ling Jing meaningfully: "But how do you know that taking care of Miss Xia is not Ling Jing's choice?"

Ling Jing, who was still indulging in what Gong Ruixue said about "my Ling Xiaojing," saw Qi Xinghai's obviously indulgent and doting expression, and his eyes darkened.

Just as Gong Ruixue was about to refute Qi Xinghai, Xiao Yuer and two servants came back with a basin.

"Miss, I didn't find the iron basin. It took me a long time to find this small iron pot from the kitchen. Do you think it's okay? If not, I'll look for it again."

Xiao Yu'er asked the servant to put the big wooden basin filled with water on the ground. Then he saw Qi Xinghai was there and hurriedly saluted.

Gong Ruixue took the iron pot from Xiao Yuer's hand. Fortunately, it was not too thick and could conduct heat.

"Okay, just this. Fill this with water and put it in a tub filled with water."

Xiao Yu'er put it away according to Gong Ruixue's request. Gong Ruixue glanced at Gong Hetong, who opened a bag of saltpeter powder and poured it into a large wooden basin.

Gong Hetong stirred it with a wooden stick and waited quietly. After a while, the water in the iron pot formed a layer of ice.

Ling Jing stood up and stared at the water in the iron pot freezing little by little. He looked at Gong Ruixue in shock: "Is this... ice?"

When Qi Xinghai heard this, he didn't even have time to ask Mincai to push the wheelchair. He turned himself to the edge of the basin and reached out to touch the ice formed in the iron pot.

"It is indeed ice. Can ice be made from saltpeter?"

For a moment, everyone in the room looked at Gong Ruixue and Gong Hetong, and they both nodded at the same time.

Qi Xinghai looked at Gong Ruixue seriously: "Do you know what this means?"

Gong Ruixue also nodded seriously: "Ice is expensive, and you can get rich by making ice. So, are you interested in doing business, Boss Qi? I'll leave this ice-making method to you, and I only want % profit. How about that?"

"You know how to make ice, why don't you do this business yourself? And how can I be sure that you won't tell others about this method?"

Gong Ruixue rolled her eyes: "I'm young, but I'm not stupid. Now that saltpeter can be used to make gunpowder and ice, why don't you tighten the control over saltpeter? Do I have to use my mind to make ice if I don't have saltpeter?" ? Why don’t we happily make money together? I have to think about offending you, the prince of the dynasty."

Qi Xinghai smiled, not knowing who just said that before he could stand up, he robbed the rich and gave to the poor.

"Okay, then let's happily make money together! Tomorrow morning, let Mincai bring the deed with him."

Gong Ruixue nodded with satisfaction: "Dad, hurry up and get me some ice for a cold compress. It hurts so much."

Ling Jing looked at Gong Ruixue and Qi Xinghai talking happily, and secretly determined that his progress would be accelerated.
