Everyone has fought to this extent, there is no way back, everyone who participated in the construction is gritting their teeth and persevering, from the morning of May 17 to the night of the 18th, the entire interception construction operation has continued uninterrupted for two days.

By the morning of May 19, the morning of the third day after the cut-off began, the crew had been working in shifts for 56 hours---- which was the longest three-shift construction in the two years since they crossed into this new world.

During this time, the work and rest time of the people in the Red Mansion were completely disrupted, and all activities revolved around the goal of intercepting the flow.

On the afternoon of the 19th, the whole river was soon to be cut off by this earthen embankment, and only one line remained, so in the cheers of the crowd, the last 20 large and small triangular cement blocks were thrown into the river by the loader, and then the bulldozers on both sides pushed a large number of stones into the water, and the turbulent river water in the narrow place was forcibly blocked, and some cement blocks were even washed and rolled by the turbulent river.

At this time, the people standing on the roof of the Red Mansion and the embankment in the distance looked nervously at the small gap that was about to close, and although the gap was less than ten meters wide, the river there had become turbulent.

More concrete blocks were thrown, and bulldozers pushed the earth into the water in time, but they were washed away almost quickly.

Under the nervous gaze of everyone, several huge cement blocks were thrown into the water by the loader, and after splashing, finally, several of them stood firm like mainstays.

As a result, in the cheers and cheers of the onlookers, more cement blocks were thrown, and each input would trigger cheers or exclamations from the onlookers.

In this way, the people struggled with the river for nearly an hour, and at six o'clock in the afternoon, when the sun was about to set, the river was finally tamed.

At this time, the river still overflowed the concrete blocks on the dam, but it had become a trickle, and as a large amount of earth and rock was pushed into the gap, the earth dam finally closed.

At 11 o'clock in the evening, the earth dam was one meter above the water and 20 meters wide, and at 6 o'clock in the morning of the 20th, the last bulldozer and loader operators finally got off work, and the earth dam had become an earth-rock dam that spanned 240 meters from east to west, 30 meters wide, and 2 meters out of the water.

Of course, this is not a real hydroelectric dam, but a temporary dam, and after the completion of this project, the construction of a real cement dam will officially begin behind the dam.

In the days that followed, the dam was reinforced, and the dam was widened by another metre to ensure that nothing was left to chance, and the Moon River was finally lowered to a minimum, and the main channel was completely diverted, with the water flowing downstream through the diversion canal, so that the pressure of the temporary dam was minimized.

According to the follow-up construction plan, behind this section of earth-rock dam, a reinforced concrete dam will be built to connect to it, and this concrete dam will eventually be integrated with this temporary earth dam to become a dam with a width of 40 meters and a length of about 260 meters.

At this point, people finally breathed a sigh of relief.

Those two days were a full day off, and people who were extremely tired almost all slept in bed from day to night.

On Wednesday, May 23, after only two days of rest, the people had not recovered from the car battle of the previous few days, and the trial production of the glass factory began in full swing.

At yesterday's regular work discussion meeting, Captain Gu proposed:

How about setting the long-awaited ocean sailing day for next Monday?

That is, May 28.

Captain Gu explained that just like choosing a day with the word "eight" when a business opens, this day is very appropriate.

A group of young people were so excited that they forgot their fatigue, so when Sun Lao suggested at the discussion meeting that in order to seize the time to carry out the trial production of the glass factory, the date should be set for tomorrow, no one shouted tired and objected.

Glassware and glass mirrors are commodities that are highly anticipated, and in this era, especially in the East, glass is still a rather rare thing.

You must know that in the Qianlong period in the history of the old world, if a set of glass teacups were taken out from a certain palace to drink tea and entertain guests, it would make the guests amazed.

And in the era where everyone is now, Emperor Qianlong and his father Emperor Yongzheng are still the liquid in Kangxi's body, so in this era, you can imagine how valuable glassware is.

As for the glass mirror, it is even more valuable, in the current historical period, the production method of the glass mirror, even in Venice, where the glass industry is very developed, is also a top-secret process, so the technological monopoly has led to the European silver-plated glass mirror in the East is very expensive.

However, from the historical sources, we already know that it would be about seven or eight years before the Venetian craft would be acquired by the French, and then the technology would begin to spread widely.

For this reason, the Sun King, Louis XIV, also built a Hall of Mirrors at the Palace of Versailles to display this new gadget, but this will be more than twenty years later.

In the East of the Old World, glass mirrors did not flow into the people on a small scale until the late Qianlong period, or even the Daoguang period.

Therefore, the current market price of glass mirrors should be much higher than that of sugar and spirits.

As for the specific price, Zhu Beiguo consulted a lot of information, and finally did not come to a detailed conclusion, but there is a reference price: not long ago, the Dutch gave a gift to the Shunzhi Emperor among the glasses and glass mirrors, which are said to be "worth a lot".

Zhu Beiguo also told everyone that during this period, the market price data of Macao, the main foreign trade port in the south Chinese mainland ----, showed that a pair of small tall glass wine glasses, the kind whose transparency was not very good, actually sold for ten taels of silver! But Zhu Beiguo still hasn't found the exact price of the glass mirror.

The reason is that glass mirrors themselves were scarce in this era, and even fewer were sold to the East, so reference materials such as local market prices were really scarce, and the reference value of a small number of tributes for market research was really limited due to the isolation of samples.

In any case, it is certain that glassware and glass mirrors are high-priced luxury goods in the market, and that the price varies geometrically with the size of the mirror.

Therefore, although the specific price is not clear, it is certain that our glass products should be able to sell at a good price, of course, provided that our glass transparency is higher than that of the Venetian, the smoothness must also pass, and there must not be too many bubbles.

In view of the fact that Zhou Rui and Yue Chu had worked as workers in the glass bottle factory, the two of them also participated in the whole process of trial production, as the saying goes, they have never eaten pork and have seen pigs run, and the two of them are considered to have practical experience in this group of people, so the chemical team and the mechanical group have absorbed these two into the equipment research and installation team very early.

Overall, this trial production team has been trembling in the process of equipment installation and commissioning, the reason is very simple, no one is a real professional, at most there is theory but no practice, although everyone has seen a variety of information in the computer data room before the trial production, including the video of the process flow, and even the video of the old world glass production site, but it is really to install and debug the equipment by yourself, and operate the production process by yourself, everyone is still very nervous.

Anything, when you do it for the first time, it will always make people feel empty, but Wang Xuezhao, Mr. Luo, Boss Luo, these bigwigs are satisfied with everyone's work attitude, and the more rigorous the initial work, the more guarantee the follow-up production.

For the so-called "newborn calves are not afraid of tigers", it is not suitable here, because, in this world, only newborn calves who don't understand farts are not afraid of tigers.
