At the Jeju Island Shipyard Pier, there is a lot of noise, and every four of them carry a large wooden box full of supplies. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info Going back and forth between the boats and the warehouse by the dock, although everyone was sweating profusely and tired and looking tired, no one stopped to rest or lazy.

Zheng He and Tang Ming walked side by side on the dock, the busy but orderly handling of goods made Zheng He very curious, he pointed to the big wooden boxes carried by those big men and said: "What are they moving now, why do they only see these wooden boxes of the same size, from just now to now, the miscellaneous family only sees these wooden boxes on the dock, and no other materials are seen?" ”

Tang Ming smiled, talking about these wooden boxes he still thought about it painstakingly, and had already started to use standard cargo assembly boxes on Jeju Island and Ryukyu. This is also a reference to the containers of later generations, the purpose of which is to maximize the loading of the ship, so that it can also make loading and unloading easier.

The two of them happened to come to a pile of wooden boxes parked on the dock ready to be loaded, Tang Ming glanced at the X mark drawn with charcoal on the wooden boxes. The attendant opened the box, pointed to a round black porcelain jar inside, and said to Zheng He: "These wooden boxes are tailored to the size of our current ships, and their purpose is to be able to load and unload them in a unified manner. ”

Tang Ming picked up a black ceramic jar again, and said with a smile: "Father-in-law, do you know what this is?" ”

Zheng He glanced at it casually and said, "It's just a ceramic jar!" ”

Tang Ming smiled undiminishedly, and did not explain to him, but ordered someone to take it to the beach, and then ordered it to be detonated. The guard, apparently familiar with the thing, pulled the string from the mouth of the jar and threw the jar into the sea.

"Bang!"

With a high splash of water, a loud noise startled the porters who were carrying wooden boxes in the distance, and only when they understood what was going on did they resume their work.

Zheng He was taken aback, and looked at the sea that had not completely calmed down: "This ......." ”

Tang Ming explained with a smile: "This is the academy on Jeju Island that is called a crooked sect, and I named him a mine." You can tie a buoy and arrange it on the sea, and if a ship passes over it and touches those floats, it will explode, but unfortunately the power is not great enough. You can only blow up those wooden ships that are not equipped with iron plates, like our current ships with iron plates on the bottom, which is completely ineffective. ”

Zheng He was stunned for a long time, and he didn't know if he had heard Tang Ming's words later, and he dared to conclude that as long as the ship was blown up, it would only be sunk. This is an explosion at the bottom of the ship, even if it is only a small hole, it cannot be remedied at all, and even if it can be remedied, the ship will not be able to continue to join the battle, which is equivalent to invalidation.

It's unimaginable to think of dissatisfaction with these things in a sea area and the consequences of those fleets passing by without knowing it.

Zheng He, who was surprised, calmed down after a long time, swallowed his saliva and said, "Have you ever practiced this thing?" ”

Tang Ming nodded, and said bluntly without caring about anything: "Last time, Zhu Gaoxi brought his father-in-law's fleet to attack me, but he was directly blown up by my mine, and more than a hundred warships were directly blown up by my mines. In order to find out what this mine was, the guy sent people to the sea many times to see it, but a large number of sharks came and detonated all the mines there, and at least a few thousand people died. ”

After speaking, Tang Ming carefully paid attention to Zheng He's expression, but there was no expected anger, he just frowned slightly and said, "Is the cost of this thing high, will it be very troublesome to manufacture?" ”

After all, Zheng He understands things at sea, and although the power of mines is not small, if you really want to apply it to the battlefield, you must have a certain number of them, otherwise it will not be effective at all. Where the sea is not as restricted as on land, these mines are too expensive to build or a problem to make. If the cost of mines equivalent to blowing up a ship is higher than the ship itself, then these will become chicken ribs.

Tang Ming didn't say anything, and once again ordered someone to bring a mine and knock the porcelain jar open, which was only gunpowder and some small angular stones. He pointed to these things and said: "The cost is not high and it is not troublesome, but this clay pot costs money after all, and the oil paper used as a seal is more material-intensive, and the rest is nothing." ”

Zheng He secretly thought about it in his heart, nodded and didn't say anything more, and got into the carriage with Tang Ming and returned to Jeju City, which was already quite large. Since the advent of cement, whether it is Jeju Island or Ryukyu Island, Tang Ming has used cement to build cities, and the roads and city walls look extremely neat.

When Zheng He returned to Nanjing, he was directly arrested by Zhu Di and taken to the palace, and he had not yet had time to see the cement roads paved with cement in the Ming Dynasty, which would be very curious to see such a neat environment and these strange houses.

"What's the paved thing on this road, it looks sturdy and flat, and this house is strange?" Zheng He looked out the window with his eyes and asked without looking back.

Tang Ming was stunned, and then remembered that when the cement was really used, Zheng He had sailed out to sea before he saw it, and it was inevitable how curious he was about this thing. It was a good explanation for this, and when Zheng He understood, they also went to the deepest part of Jeju City, the Tang Mansion under Halla Mountain.

Yao Guangxiao was when the ship docked, Tang Ming ordered someone to send him to Fang Xiaoru's academy, the old man now lives in the academy, and he rarely goes out, every day is to teach and play chess invented by Tang Ming with a few old men who can still talk, and guard his family to live a good life, not to mention how comfortable he is.

Yao Guangxiao's arrival obviously made Fang Xiaoru feel very relieved, and he took Yao Guangxiao around his academy, constantly showing off his great achievements. It's just that he didn't say a word about the technical college across the wall, and even had a disdainful look in his eyes from time to time.

The group of mud legs with no cultural background in the academy have expanded the technical college several times, and recently they even made a thing called a water mine, which made Tang Ming so excited that he kept praising him. For this reason, a large bounty was allocated, saying that it was as encouragement, and Fang Xiaoru, the old man, was so angry that he couldn't eat well for a few days.

When Tang Ming and Zheng He came to the academy, Yao Guangxiao and Fang Xiaoru were chatting in the small pavilion at the foot of Halla Mountain, and the atmosphere was very harmonious. (To be continued.) )
