Comprehensive Video: Daily life from the courtyard

"Very good, it looks very tall, but there is a problem, the system, what do you think I can do with this technology at this point in time, is it practical to leave the laboratory?" Lin Nan stared at the screen on the board. Chemical Industry ([-]) Ask the system.

"Ding~~ Host, you have to believe that there are only people who can't use technology, there is no technology that can't be used, and chemical engineering is a relatively practical technology.

Such as oil refining, metallurgy, energy, light industry, petrochemical. These are all inseparable from the technology of chemical industry. You think it is not practical for the host because the level is too low, or the original owner learned relatively simple in this period of time, and it is not as good as when the original owner became an expert later. amount of knowledge.

You can spend points to upgrade the host, the upgrade is more cost-effective and can be used in the mission world in the future, or you can choose to buy the blueprints or recipes required by the host, but this is for one-time use. "

Lin Nan opened the bathroom and walked to the sink. While turning on the faucet to wash his hands, he asked the system: "How do you increase the points for upgrades, and how do you count points for one-time blueprints or recipes?"

"Ding~~ There are eight levels of chemical engineering, and the host is now at the level of basic theory and conjecture.
180 points each time before the skill upgrade to level [-], and [-] points for special items to upgrade to the next three levels, but since the host is upgrading for the first time, [-] points can be discounted for only [-] points.

The blueprints purchased at one time were invented in the 60s where the host is located. For all the new technological products related to chemical engineering, the host can choose three kinds of blueprints to buy and use, and each blueprint is [-] points."

Lin Nan thought, no wonder the first two worlds didn't allow him to spend points, so they kept them for himself!But he still gritted his teeth and asked: "Does the second level include all modern chemical new technology products, or only 60s blueprints or recipes?" Lin Nan wanted to compare which is more cost-effective. If upgrading is similar to buying blueprints, then There's no point in upgrading.

"Ding~~Includes all the new chemical materials and technology products from the 80s to the [-]s, not trapped in the region"
"Well, let me think about it first." Ouyang Yi has been in contact with energy in the Beijing Research Institute, but now he has boarded the train back to Qingdao. Although he also works in the Qingdao Research Institute, the funds for technical equipment But heaven and earth are different.

In addition, I still have the status of a returnee. Forget it, forget it, wait for a while, and make a decision according to the situation.

"Ding~~Okay, host."

Lin Nan dried his hands and returned to his seat. Not to mention, compared with the crowded seat car in front, his sleeper in the room of four is quite comfortable.

Seeing that none of the other three people in the carriage said a word, they lay on the berth and closed their eyes to rest their minds. Lin Nan followed suit.

Woo woo,
Lin Nan got off the train with his briefcase and suitcase, and saw An Xin in a long green dress waving to him on the platform.

"What are you looking at?" An Xin asked seeing Lin Nan staring at her side.

"Looking at you, I always feel that you are much thinner than half a year ago. Is it because of your poor appetite or your body?" Lin Nan explained with a chuckle, and then cared about An Xin's body.

"No, it's almost the same." An Xin smiled softly. She was really afraid that Ouyang Yi would ask why he was the only one who came to pick him up. After all, every time he came back to his home, it was a big deal, and even his eldest brother would take time to pick him up. Right now he.

She had prepared a bunch of comforting words in her heart, but she didn't expect that Ouyang didn't say anything, but cared about her physical condition instead.

"How can I do that? I used to work in Beijing and couldn't take care of you. Now that I have finally been transferred back, I have to try to get you a white and fat child." Lin Nan said to An Xin with a teasing smile.

"What are you talking about? I hate it." Although An Xin was a little shy, she was still full of expectations for Ouyang's words.

The two have been married for many years because of work reasons. They get together less and leave more. Hearing the news of An Jie's pregnancy, he was also envious, but now that Ouyang is back, his and Ouyang's baby will definitely come soon.

The two walked to the train station talking and laughing, looking at the rickshaws outside, Lin Nan pointed to his watch and said to An Xin: "It's only after one o'clock in the afternoon, brother should still be at work now, why don't we go back to our own home first, After four o'clock, I went to the elder brother's house for dinner."

"Okay, let's go home first." An Xin thought that when she came out, her sister-in-law had already had lunch and was preparing dumplings, so she just needed to get home before her eldest brother got off work.

Lin Nan and An Xin had a discussion, and they got into a rickshaw and went back to their small western-style building together. On the way, An Xin went to the neighborhood of Lin Nan.

After returning to Xiaoyanglou, Lin Nan put his things away and went to the bathroom to take a shower. When he came out, he saw An Xin sorting out the things he had brought back.

"Ouyang, when will you report to the institute?" An Xin asked as she handed Lin Nan the matching clothes.

"When I came back, the leader told me to go to Qingdao Research Institute to report on NO.20. Today is only NO.16 and there are four days left. I plan to arrange my family affairs first. I will report for work around the 89th and [-]th. After that, I can't rest at will." Lin Nan is going to look for the black market to buy some food, cloth, etc. Although it is not easy to buy things now, but as long as the money is in place, you can still buy them. After two years, you can really buy them with money. There is nothing left, especially with my uncertain identity, I should make a plan early, so as not to be caught off guard when I get there, then...
