In 1912.

The feudal dynasty of the Qing Dynasty ended, and the Republic of China was just established.

From July 28, 1914 to November 11, 1918, World War I broke out in Europe, with about 65 million people fighting and more than 10 million killed and 20 injured.

At this time, European and American countries grasped the post-war reconstruction and related work, and had no time to take care of China.

In 1923, Shanghai was still subordinate to Songhu City.

At this time, Shanghai was still a county.

But no matter how it changes, Shanghai’s public concession has not changed much.

The Public Concession, also known as the Anglo-American Concession, was formed in September 1863 by the merger of the former British Concession and the American Concession.

This is the earliest in the history of the Shanghai Concession, the longest existence, the largest area, the most prosperous economy, the most perfect law, the largest management institutions, and the most fully developed concession.

The area is huge, including North Huangpu, Jing’an, Hongkou and Yangpu districts in the south along the river, is the most important part of the public concession, corresponding to the public concession of the middle, west, north and east districts.

At this time.

The eastern part of the public concession.

The streets are lined with Western-style buildings and can be seen with many foreigners in suits and shoes, as well as some plainly dressed rickshaws.

Dididi….

The tram’s whistle sounded.

You can also see some small black cars passing through the road.

People come and go!

The streets are still very lively.

On this busy street, a young man looked around the streets of the concession and muttered, “1923, soon to catch the golden decade!” What a great time! ”

It is now 1923.

According to historical developments, there will be a golden decade.

The decade was from 1927 to 1937.

That is, there were still four years to go until 1927.

The man’s name is Su Zheng and he is a crosser.

To be precise, a crosser with a double piercing door.

Three days ago, Su Zheng activated the strongest fallen master system.

According to the introduction of the system, the strongest dumper can shuttle back and forth between the parallel world and the real world to sell related materials and materials.

It was his first crossing.

Traveling through this parallel world, Su Zheng learns that it is now 1923 during the Republic of China, and that he is in a public concession.

The first time the system is activated, it gives away 1 cubic centimeter of versatile space.

In addition to a piece of clothing, other materials carried by the double piercing door must be carried through the versatile space, otherwise there is no way to pass through the double piercing door.

So if you want to sell more, you have to upgrade the versatile space.

Now.

A virtual panel appeared in Su Zheng’s mind.

Upside down: Su Zheng

Level: Apprentice Fallen【Tip-down Message: Being able to make money is an excellent Fallen】

Versatile space: 1 cubic centimeter [upgradeable].

Ultimate Mission: Build the strongest family in the Republic of China (already on, in progress…) )

Short-term mission: Complete a scalping to get a rich reward.

Double door opening time: After completing a scalping, it will be opened after 15 days.

Ability: None

Points: None.

……

Looking at the virtual panel, Su Zheng took out the three-carata mosang diamond in the carry-on space, showed a smile on the corner of his mouth, and began to look for a jewelry store.

Completing a scalping is easy.

Because the versatile space given when the system is activated is only 1 cubic centimeter, it is not possible to carry large items.

So Su Zheng bought a 3-carat Mosang diamond from a treasure and brought it to the current Republic of China period.

Moissanne diamond, the name originated from Dr. Henry Moissan. Also known as moissanite, moissanite, chemical name is called synthetic silicon carbide, its appearance is similar to diamond, often used as a substitute for diamonds.

It is also the gemstone whose physical properties are closest to that of a natural diamond.

Its chemical composition is SiC, nearly colorless, refractive index 2.56-2.69, dispersion 0.104, birefringence index 0.043, hardness 9.25, density 3.22 g/cm3.

It should be known that the internal structure, numerical value and appearance of the Moisan diamond are strikingly similar to the diamond, and even if it is detected with a diamond pen, it will be judged as a diamond and it is difficult to distinguish.

But the Moisan diamond can shine brighter and more stunning than the diamond, and the price is only 1/10 of the diamond.

The fire energy of the Moissanne diamond is so beautiful because of the physical, chemical and optical properties of the crystal. This synthetic gemstone has a very high refractive index of 2.65-2.69 (2.42 for diamonds), a dispersion index of 0.104 (0.044 for diamonds) and a luster of 20.4 (17.2% for diamonds).

Simply put, there is little difference between a moissanne diamond and a natural diamond.

The 3-carat Moisan diamond ring has a diameter of 9.4 mm and a height of 5.6 mm… This can fit just in a 1 cubic centimeter size in a versatile space.

Moissanne was originally developed and researched by overseas companies in Europe and the United States with an investment of 45 million US dollars, and launched a patented product in June 1998.

It’s only 1923, and there’s no such thing as a moissan.

Using a Moisan diamond to impersonate a diamond is not an easy and simple thing….
