Zhu Jingjing carefully held the medicine box in front of her and asked softly, "Brother, is this medicine really that effective? If I get seasick, will I be fine as long as I take it?"

Jiang Chuan nodded slightly: "I haven't tried it myself, but many people online say it works, and it's best to eat it before boarding the ship."

Hearing this, Lin Xiaoyu frowned slightly: "Isn't seasickness medicine supposed to have side effects? Jingjing might not even be seasick yet, so I think it's better not to rush to give it to her."

Jiang Chuan glanced at her, then looked at Zhu Jingjing: "That's true, but seasickness medication is best taken in advance. If you wait until you're actually seasick to take it, the effect will be greatly reduced! Jingjing, the most common side effects of this medicine are drowsiness, weakness, and difficulty concentrating. Think it over yourself, whether you want to take it now or bring it on the ship just in case."

After hesitating for a moment, Zhu Jingjing put the medicine in her pocket. "Then Jingjing should hold off on taking it for now! Otherwise, if she gets sleepy before even having any fun, it'll be a huge loss!"

The Great Ming Dynasty, Fengtian Hall.

Zhu Yuanzhang looked up at the sky, his eyes fixed on the small box in his beloved daughter's hand.

"If this medicine had existed back then, how many fine young men of our Ming Dynasty could have been spared becoming lonely souls at the bottom of Poyang Lake!"

He sighed deeply, as if he could see again the scene of his bloody battle with Chen Youliang on the lake that year, with ships burning and waves turning red.

"Chongba, the past is like smoke, don't be sad anymore." Empress Ma saw the sorrow on his face and gently advised him, "If we govern this Ming Dynasty well and make sure that all the people in the world have enough to eat and wear, that will be the best tribute to those fallen soldiers."

Upon hearing this, Zhu Yuanzhang nodded heavily and said in a deep voice, "I will remember your words, my lady, forever!"

The Great Tang Dynasty, Taiji Palace.

Upon hearing Jiang Chuan's words, Li Shimin frowned slightly.

"Minister Zhang, although our Tang soldiers are skilled in land warfare, their naval skills have always been lacking." He pondered for a moment, then slowly said, "The training of our navy for this expedition against Goguryeo will depend entirely on you."

Zhang Liang solemnly cupped his hands and said, "Your Majesty, rest assured, before we set out on the expedition, I will do my utmost to train the Tang Dynasty's navy well."

Li Shimin gazed at the sky and sighed softly, "If we could obtain that seasickness-inducing medicine from later generations, we could greatly shorten the time needed for military training. Minister Zhang, is there anything similar within the borders of our Great Tang?"

"Your Majesty, although I have not personally tested them, there are indeed some folk remedies circulating among the people." Zhang Liang pondered carefully and replied, "Some say that drinking children's urine can cure it, others say that sugar water has a miraculous effect, and still others carry 'soil from the hearth' to cure water-related diseases."

"Absurd!" Li Shimin's face darkened, clearly disapproving of such unorthodox methods: "How can such rural techniques be applied to the army? If there is truly no better solution, then the only way is rigorous training, forcing the soldiers to overcome it through sheer willpower!"

A giant ship loomed before us, like a floating city rising from the sea.

Zhu Jingjing looked up and froze on the spot.

She had seen cruise ships on TV before, but at the time she only found them novel and didn't feel much about them.

But when this colossal object truly stood before her, all her imagination shattered instantly.

"This...this is way too big!"

She involuntarily took a step back, trying to bring the entire ship into view, but found it impossible.

From left to right, the entire view is of the ship's hull.

The snow-white paint shone brightly in the sunlight, and the dozen or so decks stacked one on top of the other, like a skyscraper lying on its side.

Hundreds of portholes were densely packed together, and behind each one was a room she could never have imagined.

"Xiaoyu, pinch me!" Zhu Jingjing tugged at Lin Xiaoyu's sleeve, her voice slightly shaky. "Is this really a ship? It looks bigger than my father's imperial palace!"

Lin Xiaoyu smiled but didn't make a move, while Jiang Chuan pinched her arm without any hesitation.

"Hey! Brother, why are you using so much force!" The little princess pouted and glared at Jiang Chuan, but her anger was quickly dispelled by excitement. "It wasn't a dream! How did such a big thing float on the water?"

Jiang Chuan pondered for a moment, then replied, "Jingjing, let me ask you, if an empty iron box were to float on water, could it?"

"Of course!" Zhu Jingjing replied without hesitation.

Lin Xiaoyu asked, "What if we squeeze this metal box into a ball and turn it into a small metal ball?"

Zhu Jingjing thought for a moment, then gently shook her head: "Then it will definitely sink to the bottom."

Jiang Chuan nodded in satisfaction: "Now you understand! This cruise ship is like that empty iron box. Don't be fooled by its size; it can still float on the water. The key is its displacement! As long as the displacement is not less than the weight of the cruise ship itself, it can float safely."

"I understand! No matter how heavy it is, as long as it's hollow, it won't sink!" Zhu Jingjing nodded thoughtfully.

Although she didn't quite understand the concept of "displacement," she roughly understood why the cruise ship didn't sink.

"While not absolutely true, it's pretty close," Jiang Chuan said gently, ruffling her hair affectionately. "Let's get ready to board the boat. From now on, you must stay by my side obediently, or if you fall into the sea, no one will be able to save you."

The Great Ming Dynasty, Fengtian Hall.

"Chongba, is this truly a ship?" Empress Ma exclaimed in shock, her voice trembling, "This is no ship, but a floating pavilion!"

Zhu Yuanzhang frowned and said in a deep voice, "I always thought that Chen Youliang's hundred-zhang warships were already extremely exaggerated, but who would have thought that later 'cruise ships' would be even more magnificent!"

Empress Ma stared intently, her horror growing: "Chongba, look closely! That 'cruise ship' isn't made of wood; it's entirely cast iron!"

Zhu Yuanzhang nodded slightly and sighed, "Such magnificent spirit! This single ship must have cost an immeasurable amount of iron. If my Great Ming also possessed such ironclad ships, even just one would be enough to patrol the seas and defend against pirates. Even if a thousand Japanese pirates came to invade, they would be no match for the might of my navy!"

"Chongba, do you perhaps intend to emulate this method and build ships out of iron?" Empress Ma frowned slightly and said, "Although I am not familiar with boats, a ship made entirely of cast iron would be as heavy as a mountain. How could it possibly float and sail?"

Zhu Yuanzhang shook his head slightly and said, "Madam, I do not intend for the entire ship to be cast in iron! However, wrapping its vital points with iron plates will not only provide strong protection but also prevent any slowdown in speed. Wouldn't that be the best of both worlds?"

Empress Ma pondered for a moment, then clapped her hands and exclaimed, "Chongba, if this method is indeed feasible, then our Great Ming Navy will be invincible at sea!"

Zhu Yuanzhang seized the opportunity and said, "Furthermore, we can place iron-cast rams at the bow of the ships. Even if a thousand sails block the way, we can still fight our way through! Only then will we be truly invincible!"

Zhu Jingjing clung tightly to Jiang Chuan's sleeve, following closely beside him.

"Jingjing, why are you so nervous?" Jiang Chuan gave a wry smile. "As long as you don't run around, you'll be fine. There's no need to be so nervous, is there?"

Zhu Jingjing shook her head vigorously, but stubbornly refused to let go of his hand: "Brother, what if Jingjing really falls into the sea? You...you really won't leave me?"
