The human rail car is not a single one. The blacksmiths of the blacksmith shop jointly made four human rail carts, each transport can reach up to forty iron bags, and it takes only one or two minutes to go back and forth, which is convenient and fast.

The slave spy was very excited to hold another lion slave. He had a scar on his face. He was also a secret spy from Saltpeter Town. The two of them exchanged the information they obtained today during their meals every day.

Now the slave spies can no longer help but share their joy with their companions. The emergence of human rail cars is enough to prove that this emerging town has advanced invention technology.

In addition, white mist evaporates and sparks are splashing in the ironworks, and there are often horrifying scenes of high-temperature molten iron flowing down the canal. The slaves often use something to collect high-temperature molten iron. It is hard to imagine how they work hard without shaking their belief in nature.

Anyway, the intelligence spy, the Lion Man, had long wanted to spread the information about the iron plant, but the work of the iron plant was too strict.

Although the secret of the ironworks is not as high as that of the gunpowder factory, orcs working here have rules of being confined. They cannot run out of their own range, and they cannot sleep outside the slave shed of the ironworks when they sleep.

Last night, he tried to pee at night and check the surrounding guards. He found that many soldiers in the town were not patrolling, so it was time to send messages to the pigeon at night.

Taking advantage of everyone's attention, he spoke with his companions in a low voice: "This human-powered rail car is very powerful. It does not require animals, and can be pushed by humans. This is a very critical technology. Can you draw a structural diagram of the human-powered rail car?"

"Yes, but I need to read it many times, otherwise I will be punished if I draw some details incorrectly." The lion spy who is good at pictures said in a low voice.

The slaves around were immersed in miracles that made great efforts to achieve miracles, and were ecstatic and did not pay attention to the two thief slaves' communication in a low voice.

...

Rumble.

The molten iron treated by the three-delay treatment was poured into a large converter, and the scrap steel bought from various places was also poured into the converter. In addition, a thin tube was penetrated into the furnace, which was an oxygen gun.

Oxygen comes from the Orc Laboratory in Tomorrow Town. Allen uses his maximum teaching ability to teach a team of two hundred people to become experimental personnel of rote memory steps.

First, using the heat absorption characteristics of saltpeter and using air freezing separation method, a large amount of high-purity oxygen will be produced.

These oxygens cannot guarantee 100% purity, and it is very powerful technology to have under existing conditions.

Then, steam engines, rubber pistons and other substances were used to make pumping and gas transporting substances, and a large amount of oxygen was input into the steel sealed container made by the blacksmith shop.

The air freezing separation method has high initial cost, but it becomes easy after success. The output is very high each time, and there are countless sources of air, so you can use it at will.

After a while, when the converter rotates, the refined steel water flows out from the specific channel port and is injected into the container to be determined. After a period of time, steel blooms will form.

"Mr. Allen, I saw the converter design drawings of the steel mill a month ago. To be honest, I am still confused now. I don't understand the oxygen gun and any other alkaline air side blowing. Can you tell me the principle?"

Abel scratched his hair. After seeing the converter successfully running, he did not check the quality of the steel blossoms. He could not wait to understand the deepest secrets of the converter steelmaking.

Allen said with a hunch, thinking of writing a book on junior high school chemistry recently, and said, "This requires you to study chemistry in school."

"Chemistry?" Abel didn't understand this word, so he could only remember the noun.

The God of Foundry is above, is steelmaking no longer in your natural realm? Do I want to believe in the God of Chemistry? Abel said in his heart.

"Yes, but the chemistry class has not started yet. Chemistry will start in one or two days, and the chemistry laboratory in the school will be initially installed by then." Allen nodded.

Chemical experiments require various transparent glass test tubes, etc., as well as rubber tubes, which require the support of glass factories and the support of small rubber workshops.

The Windsor cat next to him moved his ears slightly, eavesdropping on their conversation.

"Didn't you ask me to take the chemistry book to print hundreds of books yesterday?" Windsor's mind turned slightly.

Steam engines require physics, steelmaking requires chemistry?

Windsor secretly remembers the basic disciplines required by these industrial machines. Only by learning them thoroughly can you understand Allen's management science.

Allen didn't know the complicated thoughts of the people around him. After watching the converter run for a while, and after confirming that the steel mill is operating normally, he began to assign the next strategic task - cast steel cannons!

Cannon is the god of war!

"Well, since the converter is successful, it's time to make the next big weapon." Allen murmured.

Alan did not hide his voice and deliberately let the orcs around him hear this sentence.

With the converter steelmaking method, due to the three-metal removal treatment, the quality of the steel produced is different from the past, and the quality of cast steel cannons has also risen sharply. It is time to make cannons.

When the orcs heard Allen's words, they immediately left chemistry behind. All the ideas that emerged in their minds were muskets, flintlocks, and smoothbore guns.

"What is the next big weapon, or a gun?"

"Since it's a large one, it should be a large musket."

Powerful weapons can give villages and towns a great sense of security. With them, you are no longer afraid of random beast tides, and you are not afraid of settlement of the accounts in the future of the Lion Heart Kingdom.

"You guessed it right, it's an enlarged version of the musket, but its appearance is a bit different from what you think." Allen shook his head and led everyone into the steel plant's director's office.

There are not many orcs who can participate in the training because this is a new technology and a new secret. Most of the orcs who come to listen are blacksmiths in the blacksmith shop, and a few are orcs such as Windsor and the steel factory manager.

When the orcs that were due to come gathered in the public office, Allen reached out and Windsor understood and took out a strange design drawing from the small bag that had been drawn a few days ago.

The white design drawing was placed on the countertop and slowly spread out. The orcs saw a huge steel pipe with two wooden wheel-shaped hand-pushing structures underneath.

Its butt is very round and huge, but the front and middle section of the "barrel" becomes thinner.
