There is a world of difference between the LEGO bricks produced in the 30s of the last century and the plastic LEGO bricks of today. The Lego bricks of the last century were made of logs, all real wood, and the wood used to make this set of Empire State Building is actually a kind of cedar.

It is one of the hardwoods, both in texture and hardness, and the joints of building blocks are a bit like the mortise and tenon structure in China. And it is also hand-painted, natural dyes are very rare, the old expert saw such a good toy, his eyes lit up and he shook his head in admiration.

"Good things are really good things, it's actually pure wooden Lego building blocks, I've seen only two sets when I'm so big, but I didn't expect to see a third set today."

As soon as Yang Nianzhong, who was on the side, heard this, he was excited, and looked at the old expert while wiping the hot sweat on his head and said. "It's not such a coincidence that you actually saw three sets of Empire State Building bricks made of commemorative logs from the Lego Company in the United States. Do you know whose hands the other two sets are? Can you give me his contact information, I'm really useful. ”

This antique restoration expert is almost 70 years old this year, but he wears a very particular suit and leather shoes, and his shoes are shiny enough to be used as a mirror. With gray hair and a clean face, wearing a pair of black-framed glasses, and blue eyes, he had just patronized and looked at the building blocks, but he didn't expect that the young man in front of him was his employer.

The employer asked, of course the old expert had to answer, looking at Yang Nianzhong's curiosity, he smiled, shook his head and said. "Your joke is a bit big, I said I've seen the Le Plateau wood building blocks, but I didn't say that the log blocks I've seen are built up to build a commemorative version of the Empire State Building, but just ordinary toy building blocks."

As soon as he heard this, Yang Nianzhong put his heart in his stomach, and pointed to this set of building blocks and sent it to the auction to exchange for money, if there are several sets of commemorative Lego bricks in the United States, then this set in his hand is not precious, rare is expensive, why is the price of good things so high.

One is that the output is small, and the other is that the amount of survival is small, so its price will be very high, Yang Nianzhong spent so much money to get back a set of building blocks for the children's toy Empire State Building, you can't smash it in your own hands, as soon as she heard that it was an ordinary toy building block, Yang Nianzhong was relieved, and then stood up and shook hands with this old expert.

And the two female devils in the house, as soon as they saw outsiders coming, they naturally let go of the male owner in the house. When to joke and when to talk about serious things, the two women in the family can see it clearly. also said hello to this old gentleman, what should I do, leave all the things to Yang Nianzhong, this male host to complete.

The other party has already come, and Robert Butler has already negotiated the price with him, so the next step is to identify whether this set of Lego bricks is produced by the original factory. The commemorative version of the Empire State Building imported into the United States, although the surface of the black building blocks is not damaged, and the painted paint has not fallen off, but the oil stains are really disgusting.

And this toy restoration expert is very powerful, people do this business, he drove a large van, and the van of Swan Castle was loaded with his tools and some chemicals.

Although the old man did not need an assistant, he still needed the help of the Yang family to move these things to Swan Castle, and moved a few plastic boxes, all kinds of chemical bottles, to an empty room outside Swan Castle.

Because the smell of chemical reagents is really bad, and there are residues that cannot be touched by the women in the family, especially the pregnant Anne. What if I hurt my son again? In that case, my mother will not have to kill herself.

Although this empty room is empty, the operating table is there and very clean, and the old expert put these loneliness in his own, the operation box on this set of operation box.

Just like the Transformer, there is even a high-powered microscope, with the help of lights and microscopes, this restoration expert can identify which natural materials are used to paint the bricks, and which chemicals are afraid of.

After more than ten minutes, the identification expert wrote down all the chemical formulas on paper, and then personally mixed these chemical reagents and mixed them with water in a plastic box.

Then put a kind of equipment like a fish pond oxygen supply in the box, and then put the building blocks in little by little, after turning on the switch, Yang Nianzhong felt himself, and his toes trembled.

Yang Nianzhong knew that the things that were placed in the box like supplying oxygen to the fish tank were microwave equipment, because there were too many building blocks and more than a thousand pieces. So four boxes were prepared, and all the bricks were soaked in chemical reagents, and then the surface of the bricks was microwaved to the surface.

After a while, you can see that the inside of the box is like a boiling pot, and it is constantly bubbling, and the bubbles that come out have a layer of black oil stains on them.

It looked particularly disgusting, even though Yang Nianzhong's nose was sensitive enough to be so close to these chemical reagent boxes, he still didn't smell any pungent smell.

Yang Nianzhong felt very strange, walked to the old expert's side, and asked respectfully. "Mr. Kenny, I saw you mixing up those chemical reagents, and I didn't smell them. What are those things? ”

This is a trade secret related to other people, these chemical reagents, to be carefully blended and weighed, in order to protect the wood material of the building block itself, protect the natural painting on it, and wash off all the dirty substances after the building block becomes new.

This is someone's rice bowl, can you tell you? also knew what Yang Nianzhong was worried about, after all, when he came to the Swan Castle Hall just now, he saw a pregnant woman. Seeing that his employer is the husband of the pregnant woman and the father of the unborn child, can he not care about the safety of his family.

"Mr. Yang, don't worry, the things I use are non-toxic, I can only tell you that these things are all natural, not some chemical agents, after I process these, the Lego bricks will glow with the color and appearance when they appeared."

"After washing the surface with clean water, you can play with the children, there is no problem at all, as for what those things I concocted, I can't tell you, I hope you understand and forgive me."

Can you understand without understanding? This is someone's industry secret, how can I tell you? It would be nice to tell you that these things are all natural, without any chemical residues and harms.

It bubbled like this, and after more than an hour, all the bricks in the box changed color, just like the brand new ones when they first appeared, which was very beautiful.
