Dong Liang thought he could take advantage of the typhoon to stay in his study for a few days, or go to his private laboratory to tinker with small inventions.

The places where he usually spends the most time in the Heads of State are his study and laboratory.

When Dong Liang was on Iriomote Island, he built himself a laboratory with all kinds of tools including lathes, drills, and files.

After all, he is an old fitter and has very strong hands-on skills.

Sometimes I rely on my own memory to create some small manual machinery from later generations, such as seeders and tillers.

He spent most of his time improving the old machines that the Chinese had acquired from foreigners. For example, the machines in textile factories were originally obsolete and outdated by foreigners. After his improvements, they were even better than the machines currently used by foreigners.

Even more advanced.

Who gave Dong Liang a soul from later generations?

The head of state in Fuzhou City will live there for at least two or three years and will not move again in a short time, so Dong Liang set up the laboratory again.

After staying at home for two days, I helped Shang Yun make a surgical lamp.

The surgical light, also known as the shadowless light, is a necessary piece of equipment in the medical operating room. Its working principle is to use a high-brightness light source to illuminate the surgical area to provide enough light to ensure that the surgeon can clearly see during the operation.

See the surgical area.

The light source of a shadowless lamp usually uses a high-density condenser or uses multiple small bulbs to work together to produce high-brightness light. At the same time, the angle and direction of the light can be flexibly controlled through adjustable lamp heads and lamp poles.

The shadowless effect of the surgical light is mainly achieved through technical means, which can eliminate or reduce shadows and reflections in the surgical area, thereby allowing the surgeon to obtain a clearer and more accurate view during the operation.

There are no electric light bulbs yet, so Dong Liang can only use gas lamps as a light source.

The light source actually doesn't matter, the main thing is the set of mirrors. It's difficult to make if you don't understand the principle.

In order to evenly absorb the rain and dew, he helped Yang Yingying make an old-fashioned slide projector, which is the kind of old-fashioned projection equipment that writes words on glass pieces.

The main components are also light sources and lenses.

Yang Yingying is in charge of elementary education. This should be provided to schools, not only to facilitate teachers, but also to expand students' horizons.

As the center of the typhoon approaches, the wind becomes more violent.

As soon as the center of the typhoon left, the Heads of State received an emergency report.

There was a gaping hole in Mawei's embankment...

This news shocked Dong Liang.

Mawei is the site of the new shipyard, where tens of thousands of workers and their families are located.

These people turned out to be people from the surrounding slums.

The content of the report is vague, and no one knows what the specific situation is now.

However, Dong Liang quickly asked Fuzhou's troops to assemble and bring the tools they had prepared.

The center of the typhoon had moved northward at this time, but it was raining heavily outside.

There are trees blown down by the typhoon everywhere, and dilapidated houses have no roofs, revealing the broken furniture inside.

Groups of soldiers wearing raincoats gathered in the school grounds, as if the enemy had been killed before their eyes. But this time, they were not carrying muskets, but shovels, pickaxes and other tools.

Others were carrying bundles of sacks.

Dong Liang stepped down from the four-wheeled carriage. He was wearing a military uniform with a serious face. The captain of the guard put a raincoat on him.

He glanced at the soldiers in front of him and said only two words: "Let's go!"

Long before the typhoon arrived, the escort troops had already conducted emergency rescue and disaster relief drills.

According to Dong Liang, the army must not only be able to fight and kill, but also be able to protect.

In the face of a catastrophic disaster, if the army cannot come forward, then who will care about the life and death of the people?

Mawei Pier is now surrounded by a vast ocean.

The typhoon caused the seawater in the Minjiang River estuary to pour back, and the water level in the estuary rose, so the water upstream could not be discharged into the sea.

The typhoon brought a lot of rainfall again. Affected by the typhoon, it rained all over the eastern foothills of Wuyi Mountain.

The water level of the Min River rose sharply, reaching a height not seen in 20 years.

As Qingrui was the governor, he was supposed to organize the maintenance of the embankment every year.

However, he used the excuse of frequent civil unrest in the past two years to cancel the annual maintenance of the river embankment.

In fact, he did not use the money to suppress the bandits, but put it all into his own pocket.

Ever since Dong Liang led people to rob him of the stolen money that he had saved for many years, this guy began to make more money.

Another reason for the riverbank breach here is that the Mawei Shipyard dug out a lot of dry docks along the river.

A dry dock is connected to land on three sides and faces water on one side. Its basic components are the dock opening, dock chamber and dock head.

The dock is used for entering and exiting ships, and is equipped with a water-blocking dock door. The drainage and irrigation equipment of the dock are often built in the dock piers on both sides of the dock.

The dock is used to place ships, and the bottom plate of the dock is equipped with keel piers and side piers to support the ship.

The dock head is the end opposite to the dock mouth. Its plane shape can be rectangular, semicircular or diamond-shaped. The space at the dock head is part of the dock chamber, where the propeller and tail shaft are disassembled and assembled.

The dry dock is equipped with various power pipelines and ancillary equipment such as lifting, rust removal, painting and boat pulling.

When a ship enters a dry dock for repairs, first use water filling and drainage facilities to fill the dock with water. When the water level inside the dock is equal to that outside the dock, open the dock door and use towing equipment to slowly pull the ship into the dock.

After that, the water in the dock is drained so that the ship can sit on the keel pier. When the repaired or built ship is undocking, water is first poured into the dock. When the water level inside and outside the dock door is equal, the dock door is opened and the ship is led out of the dock.

During the construction of this dry dock, the original river embankment will inevitably be destroyed. Logically, a new river embankment should be built on the outside.

However, the shipyard has just started construction, many projects have just started, and officials from the Ministry of Industry have little experience in building this new type of shipyard.

Therefore this issue was not considered.

Before the escort inside the city set off, the escort outside the city had already taken the first step.

…

The workers' residential area of ​​Mawei Shipyard is built on a high ground near the river.

Because there was plenty of cement and bricks, and these workers knew they were building houses for themselves, they worked very quickly.

In just ten days, all the processes from repairing the foundation to building the house were completed quickly.

Before the typhoon arrived, they had all moved into new houses. Although these houses were not painted, had no hardened floors, and were still rough, they were very strong, with two rows of brick walls and earth in the middle to thicken the walls in winter.

Warm and cool in summer.

But at this time they fell into despair.

The row houses near the edge of the residential area have been flooded, and workers have moved to higher ground in the middle.

But the water levels are still rising...

It's raining heavily outside, but fortunately, if you squeeze into the high-rise houses, everyone can squeeze in.

If this continues, the men will have no choice but to soak in the rain outside, leaving the only houses that are not flooded to the women and children.

"Don't panic, everyone, take care of women and children, the head of state will definitely come to save everyone." The person who spoke was an engineering manager at the shipyard.

These workers were not Chinese workers. They did not know that Dong Liang once told all the Chinese workers on Ishigaki Island that he, Dong Liang, would never give up a brother.

"Manager Liu, we don't want to die. We have just had a few good days. We will do whatever you say. If there is really only one place left to stay in the end, then we will leave it to the baby." An older man said.

said the co-worker.

Manager Liu's name is Liu Yan. He is a young man in his twenties. He was a Chinese slave rescued by Dong Liang on Iriomote Island. He used to work as a craftsman on a merchant ship and was responsible for repairing the ship.

He has dark skin and looks like a middle-aged man in his thirties or forties.

In fact, everyone was already desperate. With such a heavy rainstorm, the raindrops were blown away by the strong wind.

How could the head of state save people like himself in such bad weather? Is it really like the legend says that the head of state is the reincarnation of a dragon?

"Old Wangtou, let people collect belts and make them into ropes for later use. I will take people out to have a look." Manager Liu from the Ministry of Works told an older worker.

Then he rushed out of the house with a few strong workers.

Manager Liu rushed into the heavy rain and suddenly felt a huge force pushing from the side.

At this time, I no longer care whether my clothes are wet or not, the strong wind is the most troublesome thing.

Manager Liu held his thighs with both hands, barely steadying himself.

At this time, it was not clear whether it was noon or afternoon. The dark clouds in the sky were moving quickly like dragons dancing and silver snakes, as if they were in fast motion.

It used to be that you could see the river from here, but now you can see the vast ocean all around.

There are still rolling waves on this vast ocean.

Manager Liu took the people to check around with difficulty.

Finally, we found a shallow water location on the north side of the residential area.

Perhaps because the terrain here is higher, what you see from here is no longer a vast ocean, but a shallow river.

"Manager Liu, is it okay here?" a worker asked.

Manager Liu shook his head. Although the water here is not deep, the current is too fast, and it is not certain whether there is deep water in the middle.
