If you traveled back to ancient times, while others ate Guanyin clay, you would actually have giant

I don't know why, but ever since Prince Charles visited the South China Sea, there have been more foreigners there.

At first, Zhou Wu thought it was a spy sent by the Kingdom of John, but after investigation he found that he was overthinking it.

These foreigners came from various countries, mostly engaged in trade, with a smaller number being explorers, bards, and so on.

Of course, there are also some special people. For example, recently a strange foreigner came to the dock. Everyone called him a madman because he was always acting crazy and saying things that no one could understand.

Fortunately, although Zhou Wu ordered restrictions on the activities of foreigners in the South China Sea, he did not drive them away. In fact, kind dockworkers would occasionally give this madman some food at mealtimes.

"Who is that person?"

Zhou Wu happened to be strolling around the dock today when he saw a foreigner who looked just like Einstein wandering around. He couldn't help but ask him a question.

"Sir, this man is a madman. He's been at the dock for several days. He has no money and can't understand what they're saying. He lives off the occasional handouts from his fellow workers."

The dock manager answered the questions from the side.

"Why is he here?"

"I don't know. There have been too many foreigners coming and going here lately. I don't know when this old man appeared. Fortunately, he didn't do anything dangerous."

The administrator, fearing Zhou Wu would be angry, kindly said a few nice words on his behalf.

Zhou Wu didn't care at first. He was just a pitiful person. As long as he affected others, he wouldn't drive him away. Besides, the entire South China Sea was his fiefdom. Where could he possibly drive him?

However, when Zhou Wu passed by the old madman, he was immediately stunned by what the old madman said.

"Density structure, air pressure, combustion ratio..."

The old man wasn't speaking Dalong dialect, but Zhou Wu could understand him, after all, he was a top student in his previous life.

"Old man, who exactly are you?"

Zhou Wu's words were exactly the same as those of the old madman, which shocked the people accompanying him.

The old madman, who had been muttering to himself, immediately stopped what he was doing when he heard the familiar pronunciation.

He turned his head shakily and saw that the person speaking his hometown dialect was actually a man from the Dragon Kingdom.

"Why do you speak John's language? Who are you?"

The old man excitedly grabbed Zhou Wu's arms tightly. This sudden scene terrified the guards around Zhou Wu, who quickly stepped forward to pull the old man away.

"and many more."

Zhou Wu immediately spoke up to stop his men.

“My name is Zhou Wu, and I am a high-ranking official of the Great Dragon Empire. This island is my fiefdom. Who are you, where do you come from, and who taught you those words you just used?”

Zhou Wu's rapid-fire questions only made the old man more excited.

“I am Estan from the country of John, a scientist, but in my country, they all think I'm crazy.”

Zhou Wu found it hard to believe that scientists existed in this era, and Estein looked more like a beggar than Zhou Wu could imagine that this old man was a scientist.

"Why do they say you're crazy?"

It seemed like it had been a long time since Estan had spoken to anyone he could talk to, and Estan's mood improved considerably.

“They said what I invented was evil. They treated me as a heretic and almost burned me at the stake. I secretly hid on a merchant ship and drifted all the way here, but unfortunately, I was discovered by the people on the ship and they abandoned me in this foreign land.”

Can you tell me about your invention?

"It's not really an invention yet; it's just a concept right now, and we haven't even finished the design drawings."

"What exactly is it?"

Zhou Wu's curiosity was also piqued. Since transmigrating to this world, he had been unable to find anyone to talk to or communicate with in certain aspects. Now that he had finally found someone with whom he might have something in common, Zhou Wu was naturally excited.

"Because our country, John, is also surrounded by the sea, I plan to design a ship."

"Just a ship?"

Zhou Wu was slightly disappointed; after all that talk, it turned out to be just a ship.

"Of course it's not an ordinary ship, it's a ship that can dive to the bottom of the sea."

"submarine."

"Submarine? That name does seem more fitting."

The transformation was too fast; it was a ship just a moment ago, and now it has become a submarine. But it was precisely because of this huge change that Zhou Wu began to doubt whether the person in front of him was a real scientist or just a bragging fraud.

"Estan, if I give you support, can you build the submarine you're talking about?"

"No."

Zhou Wu was furious. He had thought that with his support, Estan would be able to build a submarine, but to his surprise, the other party had rejected him very decisively.

"why?"

"Because many of the technological aspects involved in submarines are still in the dark, this is just a concept drawing of mine."

"Fuck, so isn't that just bragging?"

Zhou Wu finally experienced the feeling of extreme emotional ups and downs.

"But if you're willing to sponsor me, I have other projects."

The young man in front of him was a genuine big spender, and Estan didn't want to miss out. In this country where he couldn't even speak the language, he couldn't imagine what would happen to him if he didn't latch onto this big spender, so Estan quickly offered his own bargaining chip.

"for example?"

"What about the artillery technology? A long-range weapon that can fire 300 meters, an engineering marvel that can easily penetrate ship hulls and destroy city walls."

After speaking, Estein looked smug. The cannon was a weapon he had developed in his early years. It was indeed very powerful, but due to the material of the cannon, it was prone to bursting. Moreover, the construction cost was very high, and the high-ranking officials of John's Country were unwilling to spend a lot of money to build these things.

Estan hoped that the young man in front of him would be a discerning person.

"A 300-meter cannon? Is it that rubbish?"

"What? You call it garbage? Do you even know what artillery is?"

In John's country, at most it would be considered too expensive, but this young man actually said that his proud cannons were garbage. How could he tolerate that?

"Putting everything else aside, just the fact that your artillery has a range of only 300 meters, what is that if not garbage?"

"Hmph, talking big. Have you ever seen a cannon?"

Zhou Wu did not answer Estan's question, but called the dock manager to his side, whispered a few words, and then the manager quickly left.

Estein had no idea what Zhou Wu was up to.

"look."

Following Zhou Wu's pointing finger, an unremarkable Bull Demon King ship on the dock suddenly opened all its side firing ports, and then, to Estan's astonishment, the silhouette of a cannon slowly appeared.
