Zhang Heng estimated that one material was equivalent to one Song stone, which was equivalent to 120 kilograms in later generations. In other words, five thousand materials was equivalent to about 300 tons.

I can travel across the ocean.

That is to say, what they lack is only a compass and the knowledge of navigation, but nothing else.

Zhang Heng asked Fan Wuji to take out a compass that he had made before he arrived. Zhang Heng originally wanted to make an exquisite compass, but because he was not very familiar with compasses, he could only make a simple one with east, west, north and south on it.

, and then marked the scale to achieve higher accuracy.

Zhang Heng gave Zhang Mazi and others a try, and everyone was immediately delighted: "With this compass, we no longer have to worry about getting lost at sea."

Zhang Heng smiled and said: "I roughly understand the situation. In fact, all the things you are worried about can be solved.

If you are afraid of losing your way, use this compass. The ship can be built larger. A ship of 5,000 materials is enough to cross the ocean.

I believe it is not impossible to build a bigger ship as long as you give money, right? As for the miasma you are talking about, it is actually just a lack of vitamins... You don't have to worry about what vitamins are, but you can avoid them by eating tea and bean sprouts.

You can bring tea and beans, and growing bean sprouts on the ship is enough to avoid this so-called miasma. So, is there anything else that can hinder you from crossing the ocean?"

Zhang Mazi's scalp felt a little numb: "But... it's really far away. I don't know if I can make any money on this trip. If there is a storm, the whole army may be wiped out."

Zhang Changping said: "Prefect Zhang has thought of this for us, why should we hesitate? Zhang Mazi, aren't you the bravest all the time? Why are you so timid tonight? Did you forget to bring your eggs before going out?

?”

Everyone laughed suddenly, and suddenly someone noticed Lu Yining and quickly stopped laughing.

Zhang Mazi was immediately ashamed. In order to save face, he cursed loudly: "Who dares not to have eggs anymore? I just thought more. The so-called more calculation wins more, less calculation wins less, this is what the wise say."

Why, how can I be so reckless like you!"

Zhang Heng smiled and waved his hands and said: "This is a long-term plan. It will take time to build such a big ship.

You can try it slowly. You don’t have to go very far. You can go to Bo Ni Country first, and then try to go around to Zhenla Bagan.

When you have accumulated enough experience, you can continue to explore Arabia and the like, and one day you can even reach the Byzantine Empire in the far west of Europe!"

Hearing what Zhang Heng said, everyone felt relieved. If they were allowed to cross the ocean all at once, it would really be a near-death situation.

"so……"

Zhang Heng looked at everyone and said: "...if the thousand-material sea-going ships you ordered before have not been started, ask the shipyard to stop them. In the future, all ships will be built into large ships with more than five thousand materials. As long as the technology is reliable,

, as big as it is, it will be as big as it is!”

As soon as Zhang Heng said these words, everyone immediately looked at each other.

Zhang Heng said in surprise: "What?"

Zhang Changping smiled bitterly and said: "Well... we may not have that much money."

Zhang Heng smiled and said, "Isn't this possible?"

Zhang Mazi rubbed his head and said, "These five-thousand-material ships are too expensive. We simply can't afford them. It's okay for each of us to order a few thousand-material ships, but we are powerless to order a thousand-material ship."

Zhang Heng suddenly realized: "You mean, you and your family don't have that much money to order a big ship, right?"

Zhang Mazi slapped his thigh: "That's what it means!"

Zhang Heng smiled and said: "So you are worried about this. Don't worry, I am here to solve your problem this time..."
