Because of this special property of the ore, Li Hao called it 'manganese'.

"Theirs is called stainless steel, and ours is called manganese steel! Be fierce with them, be good at them! ”

"Our Great Celestial Empire is invincible! Manganese steel! Manganese steel! Your Highness is mighty! Your Highness is mighty!! ”

In the excitement, the blacksmith and the Ministry of Engineering cheered and lifted Li Hao up and threw him into the air.

"Don't, don't! This is not the credit of Hongu alone! And my second uncle, Yanyu, and the big guy! ”

"Come on, don't be modest. If it weren't for your stubbornness, this thing would have been thrown away a long time ago! ”

Facing Li Hao's cat-like face, Zhang Shijie was both distressed and relieved. I couldn't help but think of the monk's words again, it seems that this kid is really not ordinary, and he will definitely find a way to go back with him.

After Zhang Shijie finished speaking, the blacksmiths also felt happy. To be honest, if it weren't for Li Hao's persistence, they would never have discovered the mystery.

"I have to go back to His Highness and don't accept it, otherwise, this thing is really not even a gambling stove pit!"

"Isn't it, a hammer goes down, and it's crispy! Who would have thought it would be deceiving! ”

The big guys are gossiping, but Shen Yu is very quiet. Although he didn't say a word, the burning in his eyes was worth a thousand words.

At that moment, Li Hao couldn't have been happier. For the first time in a few months, Shen Yu looked at himself like that.

"Let's roast the whole lamb in the evening! Big guys eat and drink as much as they want! ”

"Thank you, Your Highness!"

The successful development of manganese steel quickly set off an earth-shaking change.

Due to its strong wear resistance and toughness, it was soon widely used in various fields such as military and industrial and agricultural production.

It is also by virtue of this that Li Hao won high praise from Jinzong and his courtiers. The monster talk has come to an end for the time being.

On June 14, Li Hao took Shen Yu to a small tributary of the Bahe River to test the installation of the floodgate.

This small river is an artificially dug irrigation canal, running north-south and only 20 meters wide at its widest point, which is suitable for this experiment.

On the day of the successful development of manganese steel, Li Hao ordered the Ministry of Engineering to build the dam foundation first.

Don't look at it as an experiment, but it's meticulous. A series of processes are strictly carried out according to the standards of the Sanmenxia Dam.

The skeleton of the dam is made of newly developed manganese steel steel bars, and not only that, but the concrete poured in the middle is also very particular.

Li Hao made a new attempt by mixing the granite powder sieved from the gold mine with a part of volcanic ash and other materials in a certain proportion into a slurry.

For the sake of the strength of the dam, he worked hard, and even the anti-corrosion problem of the sluice gate, he also took great pains.

Before finding a suitable method, Li Hao also wanted to go to the gate to cross the gold and silver, and after many experiments, he finally locked the substance of Lou lead.

So what is floor lead?

In fact, it is known as zinc.

Metal galvanized solves the problem of corrosion.

As long as you are willing to think and do, there is nothing that cannot be solved.

It was this persistence that Li Hao discovered that Lou Lead still has this characteristic. Unintentionally, he made a great contribution to the Celestial Empire.

The power of love is huge, and it has been appreciated by Shen Yu, Li Hao is full of confidence and his brain is more flexible. Think what others dare not think, and do what others can't do.

In just half a month, Li Hao seems to have changed as a person. Even dreaming is what it is, what it reacts to, what it can produce.

After some debugging, the installation of the zinc gate was completed.

"Your Highness! Gate installed! ”

"Yanyu, take a look at it again, if it's okay, we'll have to test the water."

"There is absolutely no problem with the gate, it depends on the dam!"

"The dam is harder than stone, so don't worry. Water!! ”

With Li Hao's order, the sergeants opened a big hole in the main river.

In an instant, the river poured into the dam below the slope as if it were a joy.

In a short time, the small reservoir was filled.

The gate was installed seamlessly, and there was no water leakage at all.

Seeing this, Li Hao looked at Shen Yu proudly.

I thought that Shen Yu could give him a smile, but who expected that Shen Yu's expression was still very serious.

Also, just filled with water, what can you see? If you want to see the results, you have to take the pressure repeatedly.

Only when the floodgates are all opened can we see if the dam can withstand the high intensity of water pressure.

"Open the gates!"
