"Haha, are these the elite of Great Britain?"

"Sure enough, they are a bunch of trash, so many people can't clean up a few of them."

"It seems that the 'elite' of Great Britain have fallen in the trenches."

"The rest are just a bunch of cowards."

The hound said disdainfully, as for the task assigned by Canon, he will definitely complete it with all his strength.

However, in his opinion, this is just a simple task.

After all, this is not China.

Here is the alliance of crows and swallows.

...

"Ding, congratulations to the host for familiarizing yourself with "Principles of Machine Tool Construction" and earning 1,000 credit points!"

Rubbing his eyes, the system prompts sounded in his mind, announcing that he had finished reading the book.

"No wonder, no wonder."

Yang Xiaotao looked at the books in his hands and sighed in his heart.

The original machine tool-related books were not considered complete books at all, so it was useless to read them all.

This time when I encountered the source, the system immediately prompted me.

This also proves in disguise that the books in this room are really useful.

"By the way, I seem to have forgotten one thing."

Seeing the credits suddenly turn into four digits on the system panel, Yang Xiaotao slapped his head and suddenly remembered what was going on.

"A blind box."

I rubbed my hands and went into the study this morning, forgetting that this happened.

"Open it, open it now."

People feel refreshed when happy events happen. Who would have thought that I could gain so many books here, and they would be books that are useful to me.

Isn't this kind of luck the right time to open a blind box?

After a while, Yang Xiaotao took out a palm-sized wooden box from the space.

"Is this golden nanmu?"

"The packaging is so good, the contents inside will not be bad."

Yang Xiaotao was thinking, Xiaowei also came out from the side, her little head was very curious, and she reached out to touch the wooden box.

"Wait a minute, I'll open it first."

After saying that, Yang Xiaotao pushed open the box and saw a yellow talisman inside.

Yang Xiaotao reached out and took it out, and Xiaowei immediately came forward with curiosity in her little eyes.

As the talisman comes into contact, the system prompts also sound.

"Ding, congratulations to the host for getting a sub-skill upgrade talisman."

Sub-skill upgrade symbol: After use, randomly select one of the sub-skills and upgrade it to a level.

"I go!"

Yang Xiaotao directly cursed.

You know, except for Yang Xiaotao's sub-skills, which have been upgraded to level eight, none of them have been fully upgraded.

However, there are differences among these sub-skills.

If you are randomly assigned to life skills such as fishing and cooking, you will definitely lose money.

It’s not that these sub-skills are not good. In those years of hard work, these life-related skills helped Yang Xiaotao a lot.

But as life becomes more and more stable, upgrading these life-related skills will at most increase your proficiency, and then you will get more fixed rewards every month.

Relatively speaking, work-related skills are more helpful to Yang Xiaotao.

If this is used in mechanical proficiency, it would cost 10,000 credits to upgrade from level 6 to level 7.

If you pay more than 2,000 yuan and exchange it for 10,000 yuan, you will definitely make a profit.

"The heavens and the earth are spirited, bless and bless you."

Yang Xiaotao thought in his mind, then picked up the talisman and said it silently in his mind to use it.

In an instant, the talisman disappeared into thin air as if it spontaneously ignited, leaving no trace.

The next second, a nervous voice suddenly sounded.

"Ding, congratulations to the host, the steelmaking proficiency level has been improved, and the current level is three."

"Ding, congratulations to the host, you have received the reward 'Tin-plated Iron Manufacturing Technology'."

Two voices sounded one after another, and Yang Xiaotao was stunned for a moment.

Then his face showed ecstasy.

Although he is not proficient in mechanics, his proficiency in steelmaking is quite good.

You know, it takes 5,000 credits to upgrade from Level 2 to Level 3.

This is great, it saves half of it.

Moreover, what he originally wanted to do was to improve his steelmaking technology.

But, isn’t this tin-plated iron just tinplate?

"Is it possible to use this thing to make cans?"

Yang Xiaotao didn't understand it for a while, but then he felt dizzy in his mind.

Torrents of knowledge burst out from the depths of my mind, extending and emerging in my mind.

A bunch of knowledge about tin-plated iron is integrated in my mind.

As the knowledge continued to be digested, Yang Xiaotao gradually understood what this tin-plated iron was.

I finally understood that this tinplate is tin-plated iron, but tin-plated iron is not tinplate.

It's a bit hard to say, but Yang Xiaotao understands that producing this tin-plated iron is of great significance to domestic development.

In particular, most of today’s tinplate is imported.
