Siheyuan: I want to take the college entrance examination and study to rise.

In this failure, half of their people in the Red Star Rolling Mill were pulled out, but fortunately they didn't all come out tonight, otherwise they don't know what would have happened!

The next day, the workers in the factory found out that something was wrong, and the entire Red Star Rolling Mill seemed to be more strict.

Everyone was silent about what happened last night, no one spoke, and the institute was still as strict as ever, everyone who came in and out, what they did, where they went, what time they went out, and what time they came back had to be registered.

This matter will be handed over to Lou Xiao'e.

Lou Xiao'e suddenly stood up straight, "Don't worry, I will definitely

not let you down!" He Yuzhu nodded, "Lou Xiao'e, I believe that you will leave this matter to you, you must register it well, and don't let them take advantage of

it!" "Yes

, He!" She was also there last night, so she naturally knew He Yuzhu's glorious deeds, but she didn't expect He Suo not only to have a good brain, but also to have good skills.

Lou Xiao'e admired it even more, and immediately agreed.

"Don't worry, I won't let you down!" He

Yuzhu's decision was the first to exist in the entire Red Star Rolling Mill, and everyone felt a little unbelievable at first, this must be registered when they come out and go in, what is going on?

But under the order of Director Yang, everyone had to agree, after all, this is a matter of the safety of the entire Red Star Rolling Mill.

He Yuzhu and the secrets of the entire research institute are the most important things!

Therefore, no one dares to be careless.

At this time, he sat in the office, entered the system, and in the past two days, he has not fallen behind in learning power, and he has been shopping every day as usual.

After refreshing, a random backpack reward pops up.

He Yuzhu opened it and couldn't help but wonder.

[Congratulations to the host for accumulating points of 600,000, rewarding 40 catties of pork, 20 pieces of great unity, a TV material package, and a design drawing of an

anti-theft door lock......] He Yuzhu suddenly became happy when he saw it, he was really sleepy and sent a pillow, and the design drawings of the anti-theft lock were really practical.

The current lock is bent into a nest with an iron wire, stuck between the wires, and opened with a flick to both sides, or it is a chain lock or an anti-pry door crane.

But if you use a little force, you can pull it open.

The earliest anti-theft door is an iron plate below, and a block-shaped iron mesh is installed on the outside of the original wooden door.

The lock is also very simple, and it was only in later generations that a regular anti-theft lock door appeared, and a cat's eye was installed, which changed from a single insurance to a double insurance, and the three insurances even had fingerprint retrieval.

Now that the technology is limited in this era, he can only make mechanical locks, so he began to research.

In fact, the lock is very easy to make, and after reading the drawings, I will understand it at once, and there is nothing complicated.

If it can be manufactured, then the door of the institute can be renewed.

The door of every office can also do this, He Yuzhu was in the office, busily drew the design details and principles, and then handed them to Director Yang.

Director Yang was a little stunned when he saw this, "What, what is this?" "

Anti-theft lock, I plan to install this kind of anti-theft lock in the offices of the whole factory, so that our factory will be much safer in the future." "

The security door is made of steel sheets.

He Yuzhu handed over the information that made Director Yang amazed, "He, you can do it in such a short time?" "

This thing is not a difficult thing, but it is just a lock."

Seeing He Yuzhu's understatement, Director Yang suddenly laughed, "It's worthy of He, I will definitely help you get the materials when you wait to turn around."

He Yuzhu nodded, what he wanted was Director Yang's words.

The current He Yuzhu is the hope of the Red Star Rolling Mill, and he must get any materials he wants, which is definitely okay without Director Yang saying it.

He looked around, it still took time for Director Yang to prepare the materials, and He Yuzhu was not in a hurry, but he was hanging around in the factory when he had nothing to do.

Occasionally, I also go to the workshop to guide one or two.

He Yuzhu doesn't want to be a nerd who talks on paper, he wants to mingle with the worker's brother.

Coming out of the workshop, He Yuzhu suddenly saw a person quietly walking out of the radio station, and he couldn't help but be curious.

Yu Haitang seems to be going where he is going at this time

? Why does he look a little sneaky?

He frowned tightly and raised his feet and followed.

At this time, Yu Haitang went straight to the toilet.

Today, Xu Damao changed into clean clothes, washed his hands more than a dozen times, and began to clean after coming all morning, and cleaned himself up after cleaning.

Seeing Yu Haitang at this time, he was excited, "Haitang, you are here, I don't know what's wrong, something is not quite right in this factory in the past two days, have you noticed it?"

"I heard that it was to catch the enemy." "

Catch the enemy, no matter He Yuzhu, I'll invite

you to watch a movie today!" Xu Damao took out two movie tickets from his pocket, "You see that I asked someone

to get it, it's hard to get it!" Seeing this movie ticket, Yu Haitang's eyes lit up, and then he looked at Xu Damao, "The movie is no problem, but when can you come out, every day in the toilet, your body smells!"

Xu Damao has been courteous and rewarded benefits in the past two days, and Yu Haitang slowly became less resistant in his heart.

Who let Xu Damao be reluctant! Xu Damao

hurriedly said: "You can rest assured that it will be very soon, I have made hard currency, and it will be no problem to give it to Director Yang when the time comes."

He Yuzhu couldn't help but be taken aback when he heard this behind his back, hard currency, but

he didn't think much about it, he didn't have much interest in other people's objects, if Yu Haitang and Xu Damao were together, he didn't have any opinions, anyway, it was none of his business.

He turned his head and left, and after arriving at the research institute

, Lou Xiao'e came up, "He, are you free today? I want to invite you to dinner!" Lou Xiao'e's words made He Universe laugh, "Invite me to dinner

?" "What are you doing one by one?"

Yu Haitang was rejected by him, and another Lou Xiao'e came.

"Why don't you lose face, right? It's my dad who wants to see you!"

"Then I'm definitely going to go." "

Okay, you go to my house tonight, I'll ask my mother to cook you a few good dishes

!" "That's it!" Lou Xiao'e

jumped away after finishing speaking, Jiang Gong couldn't help laughing when he heard it, "He, this is a fancy for you!"

"He, I said that the little girl is also good, maybe you can think about it, she works very carefully and seriously, she doesn't look like Miss Everybody at all, there is no shelf!" "It's

good, and the work is also very hard, He Yuzhu can also see that this is a good girl in the past two days, but he already has Ran Qiuye, so forget it."

"Don't think about it, I have a partner.

Jiang Gong was a little stunned, how could he really have a target?

Why have he never seen it?
