Further down, there is also a record of everyone's home addresses, where they went to school as a child, and where they later went to work, and he has everything he wants.

Jiang Cheng couldn't help but admire Li Ke's ability to do things from the bottom of his heart, if she became his assistant, she would definitely greatly help him improve his work efficiency, so as to carry out his tasks more smoothly.

She is a good seedling suitable to be an assistant.

After the completion of the division, Jiangcheng began to concentrate on the production of organic hydrogen.

However, scientific research is a very time-consuming and energy-consuming work, especially in chemical research, and some experimental accidents are prone to occur in the process of long-term concentration.

In order to avoid injuries, Jiang Cheng decided to let everyone take a break every hour, and in between the breaks, he also prepared a variety of snacks, fruits and drinks for the doctors of chemistry, and set aside the most comfortable rest area for them to rest.

Jiang Cheng is undoubtedly the most tired person among them, with his super mental and physical strength, even if he doesn't rest, he won't make mistakes in his work day and night, it's just a lot of mental effort.

Li Ke saw it in his eyes, admiring and distressing Jiang Cheng.

One night, everyone had already rested, and only Jiang Cheng was still working overtime.

Li Ke looked at the bright and huge laboratory, only Jiang Cheng was alone, wearing protective equipment, and seriously and no one else added experimental reagents to the test tube, so that Li Ke did not feel Jiang Cheng at all when he arrived.

Jiang Cheng finally finished his work, and as soon as he turned around, he saw Li Ke sitting behind him, not knowing what he was writing.

"Why haven't you slept so late?"

Jiang Cheng walked to the automatic disinfection room, took off the protective clothing, and carefully disinfected the poison before coming out of it.

Li Ke put down the pen in his hand and looked at the tall and handsome man who walked towards her.

I have to say that in addition to his ability, Jiang Cheng's appearance is also a very eye-catching handsome guy, tall, fair-skinned, a pair of long legs straight and thin, if you look at the face, high nose bridge, big eyes, long eyelashes, it is impeccable.

Unconsciously, Li Ke looked at Jiang Cheng's face and lost his mind.

"What's the matter, looking at me like that?"

Jiang Cheng put down the coat on his arm and sat on the chair opposite Li Ke.

Li Ke came back to his senses at this time, and found that he was actually looking at Jiang Cheng distracted, and he couldn't help but blush.

“…… It's nothing. ”

Li Ke looked away with a weak heart.

Jiang Cheng is a very straight man, so naturally he doesn't understand the thoughts of Li Ke and these little girls, so she just thinks that things are out of her mind, and she doesn't think much about it, and instead picks up the notebook on Li Ke's desk.

"What were you just writing about?"

Jiang Cheng glanced at the contents of the notebook and unconsciously secretly exclaimed.

The notes are full of steps and equations for making organic hydrogen, as well as the principles and processes of the reaction, and some of the steps are even simpler and faster than what they are using now.

Jiang Cheng excitedly took the notebook in his hand, the content in it is of high value, and if it is published in the universe, it will definitely cause a sensation in the entire scientific community.

"You did all your own research?"

Li Ke shook his head, not understanding why Jiang Cheng looked so excited.

"I was fortunate enough to get an ancient book with a method for making organic hydrogen, but I saw today that the method on the notes taken by other chemistry doctors was a little different from what I saw, so I thought I would write it down and study it to see what the difference between the two different methods is."

Jiang Cheng nodded, understood.

"Isn't this way I wrote better?"

Li Ke asked suspiciously.

Jiang Cheng nodded, looking at what was written in the notebook, while distractedly explaining to Li Ke.

"Like the methods we usually make, there are mineral combustion conversion hydrogen production method, as well as water electrolysis hydrogen production method, or the method of hydrogen production through semi-water gas production, which can make pure hydrogen, but these methods have some drawbacks, such as high power consumption, high pollution, slow speed, etc., but your method greatly improves this drawback, and combines all the advantages, the person who invented this method must be a genius!"

The more Jiang Cheng talked, the more excited he became, he was so excited that he couldn't wait to find the author of that book now, and wanted to discuss methods with him and exchange experiences.

Li Ke was also very surprised by this, she didn't expect that an ancient book she saw by chance turned out to be such an advanced book, she only thought it was an inconspicuous little book, after all, when she found this book, the book had become unrecognizable, the cover was tattered, there was no title and no author's name, even the content inside was missing a page and a page missing, and the font slowly faded over time, and it was difficult to see clearly, only the content of these chapters could barely be seen clearly, so she recorded it.

Jiang Cheng heard Li Ke say this, although he was a little disappointed, but the excitement still diluted the disappointment.

"It's okay, but with this method, we can shorten the time considerably, at least in a week."

Li Ke looked at Jiang Cheng's smile and was also infected by his emotions.

With Lee's notes, after a week of unremitting efforts, we were able to produce the amount of organic hydrogen that could be used for the complete flight of the spacecraft.

As soon as this news came out, everyone was very happy and excited, and after a week of hard work, they were naturally very happy to see their research results.

"Next, we just need to inject all the organic hydrogen into the spacecraft and we're done."

Jiang Cheng ordered people to put all the organic hydrogen into the container, and then worked with Li Ke to inject all the organic hydrogen into the spaceship through a special air duct.

Although this work seemed easy, it was not easy to do, Jiang Cheng and Li Ke were busy for more than two hours before injecting all the organic hydrogen into the spacecraft, and checked up and down to confirm that it was correct.

After this week, Jack saw the whole process, admired Jiang Cheng very much in his heart, and apologized for his unreasonable behavior before.

"It's okay, I can understand what you did before, and I would do the same if I did."

Jiang Cheng generously accepted Jack's apology.

"No, I really feel very guilty, and in order to apologize, I am willing to contract all the expenses you spent during the renovation process, and I will invest 20 billion in your research laboratory."

Jiang Cheng naturally won't shirk the two billion, after all, no one will have trouble with money, so after thanking Jack, he went to the bank with Jack to go through the transfer procedures.
