Jian Si Ning was so angry that she laughed. It was her boyfriend who was harassing her, and she couldn't see it?

Women only make things difficult for other women?

She pushed Zhang Chi's arm away and said in a cold manner: "We have already formed a team, and there is no need to change teams. If you want to change people next time, you'd better discuss it with your partner first."

When Jian Sining took Wu Qiong away, she could still feel a pair of cold eyes staring at her from behind.

"Si Ning, you are in trouble now. Zhang Chi was flirting with you just now and was seen by Lin Meiyue. Lin Meiyue is a petty person, especially when it comes to things related to Zhang Chi, she is a psychopath."

Jian Si Ning didn't care much: "It's okay, I'm a lunatic anyway."

"Why are you looking for her?" As soon as Jian Sining left, Lin Meiyue expressed her dissatisfaction with Zhang Chi.

Zhang Chi said with a cynical and wicked attitude: "She is quite interesting, beautiful, with a good figure, and most importantly, she is smart."

Lin Meiyue was furious: "What do you mean? I'm your girlfriend!"

Zhang Chi's eyes revealed dissatisfaction as if he was smiling: "You are my girlfriend, not my wife, you are just playing around with her, what are you making a fuss about?"

"I don't care, just stay away from that woman..."

After Jian Sining arrived, he began to prepare the spare parts needed for the oxygen concentrator by drawing the blueprints himself.

Only then did she realize a problem. No matter how perfect her drawings were, many mechanical parts could not be made with the current productivity.

The industrial chain cannot keep up with her pace, and everything is just wishful thinking.

[Shu, the things you need are already available in the system mall, so you can just buy one~]

Jian Si Ning felt depressed when he thought of the prices in the system mall: "You black shop are trying to cheat me again..."

But she did have a new idea: "System, do you have mechanical parts for sale in your mall? Aren't they much cheaper than the whole machine?"

[Su, Tongzi just checked for you and found that there are indeed mechanical parts for sale in the mall. Taking the home medical oxygen concentrator you are currently researching as an example, the price of all the parts is only one tenth of the price of the whole machine~]

When Jian Si Ning heard this, she was immediately delighted. She only needed to purchase the parts that were not currently produced in China through the system and then assemble them. Wouldn't that save her a lot of money?

"Hurry, hurry, I need to buy a compressor, a silencer, a four-way valve, a molecular sieve, and an oxygen storage tank. The model should be according to this..."

Two days later, Jian Sining took out his theoretical research and design drawings for a small home medical oxygen concentrator and discussed them with several other team members.

Her research design was the most detailed and meticulous among all the team members, and it impressed the other team members at first sight. Not surprisingly, her home medical oxygen concentrator was identified as the common research goal of the entire team.

Jian Si Ning also specifically inquired and found out that the research topic of Lin Meiyue and Zhang Chi's group was the human heart.

This reminded her that around next year, the world's first permanent human heart will be successfully transplanted abroad, but that heart is made of aluminum and plastic, so the patient's survival period can only be maintained for a few months.

Once she has made the oxygen concentrator, her next target might be the human heart. As long as she can successfully implant it in China before the first human heart surgery is performed abroad, that would be another advantage.

Soon the day for testing the results arrived, and each group took turns sending out their team leaders to introduce their respective research plans.

Lin Meiyue and Zhang Chi's group was ranked just ahead of Jian Si Ning and his group, and their team leader was Zhang Chi.

"The research topic of our group is the application prospects and design solutions of small home medical oxygen concentrators..."
