"I told you the price in my heart, you can bargain. How much is it reasonable? It's not easy to develop my medicine. And I often give you new medicines. It's very tiring."

Gu Jing glanced at her and said that it seemed like it was very hard to study drugs. Every time he saw her, he was happy, okay?

Researching drugs and making drugs are all a hobby of Gu Lin, and she likes them very much. He has never seen her tired before. He only often sees her happy and happy when she is trying drugs on others.

"One gram of $10." Gu Jing said the price.

"Brother, do you think my medicine is garbage? $10 per gram? That's the medicine that I, a genius girl, can alarm the whole world. Is it good? It has a high value!" Gu Lin boasted that she sold herself.

Gu Jing gave her a big roll of eyes, "Okay, genius girl, I'll give you 1 gram of USD. This is the limit. Besides, I'll ignore you."

Seeing that Gu Lin had mentioned this idea, she no longer forced herself.

"Okay, we'll make a deal!" Gu Lin nodded vigorously.

Gu Jing breathed a deep breath. It was helpless to meet such a weird sister!

"However, you can't tell your mother and others about selling my pistols, do you know?" Gu Jing asked again.

"I know this." Gu Lin suddenly leaned on Gu Jing's shoulder and whispered in his ear: "Brother, tell me. How much have you made in selling pistols over the years?"

Gu Jing turned his eyes and refused to say, "Secret! I won't tell you."

"Brother, you are not honest! After making money, you don't even give your sister money? You are such a bad brother!" Gu Lin accused Gu Jing unhappily.

Gu Jing slowly wiped the cold sweat from his forehead and found that Gu Lin was so angry that it was really difficult to deal with!

"Actually, it's not a lot."

"How many? Be honest!"

"Well, it's about a few million." Gu Jing said casually.

"Millions of dollars??!!!"

"Yes." Gu Jing nodded slowly.

"Wow! Brother, you are so awesome!" Gu Lin raised a big female finger to Gu Jing, held Gu Jing's hands very intimately, and his eyes were shining: "Brother, I recently came across a pair of pink boots, which are so beautiful. Unfortunately, they are so expensive."

"How much?"

“3,000.”

"Brother bought it for you." Gu Jing nodded helplessly.

"There is also a set of pink skirts that match one."

"How much?"

“6,000.”

"No problem, I'll buy it for you." Gu Jing bit his lip and said.

"Thank you brother!" Gu Lin rushed over and gave Gu Jing a loud kiss, which was very loving.

“…”

"I haven't had enough funds for drug research recently." Gu Lin murmured.

"How much does it cost?" Gu Jing sighed.

"Not much, just 50,000."

"Okay, I'll give it to you." Gu Jing replied to her expressionlessly.

"elder brother--"

"Gu Lin, don't be too arrogant!" Gu Jing gritted his teeth and warned Gu Lin.

"Haha..., brother, you misunderstood. I just said, I'm so happy! I have a brother as good as you." Gu Lin immediately said with a flattering look on his face.

It's considered tactful! Gu Jing glared at Gu Lin, and when Gu Lin discovered his secret later, he would be threatened by Gu Lin for the rest of his life.

However, she is smart and he is not stupid. Now that his pistol has used her medicine, they are considered a cooperative relationship.

One day later, my mother accidentally discovered him and Gu Lin was also punished by him.
