This strange-shaped iron box was first brought to a sharp rise by the iron inside, and then gradually cooled down, but everyone's mood became hotter and hotter.

Zi and the old man looked at Bai Dong with wide eyes, only he had carefully observed Bai Dong just now, and found that this kid seemed to be stepping on a fixed position, and the placement of the iron box was also exquisite; He is a fool who cultivates and seeks immortals, and he naturally can't help but think about it in his heart, and the more he thinks about it, the more mysterious it becomes, the mysteries of heaven and earth, the code of the universe or something, haunting his heart for a while

After a full column of incense, seeing that the box and the iron in it had been completely cooled, Bai Dong walked over and opened the iron box, and said to Gong Yi with a smile: "Bring it to the wooden turtle." ”

"Wood Turtle"

When he came, Bai Dong asked Gongzhi to make a wooden turtle, Gongzhi was also strange about this, the turtle is a mascot in this era, it is okay to give toys to children and gifts to people, but Bai Dong also wants him to take it with him, is it to give it to this greedy Ou Yeliang?

But with Ou Yeliang's appetite, if you want to send a golden turtle or something? A wooden turtle is afraid that he will not be satisfied. However, Bai Zi has always been unbelievable in doing things, and he is used to losing straight away, so he didn't ask too much.

The wooden turtle that the male loses straight out is only one foot square, lying down, the turtle pattern on the back just divides the turtle board into nine pieces, deep left three right seven, two four for the shoulder, six or eight for the foot, wearing nine shoes and one of the number of nine palaces, it is an auspicious turtle. It's just that the turtle's belly is hollow, and there is a hole under the abdomen, which can just be placed on a five-inch long round wooden stick, and the other end of the wooden stick is connected to a square wooden support.

Ji Turtle Shou Turtle Ritual Turtle Everyone has seen a lot, but a turtle like this that can lie on a wooden stick is still the only one. Ma Qiao couldn't help but touch his nose: "Baizi." What kind of turtle is this? Ou Yeliang also looked at Bai Dong. This kid doesn't want to verify the divine iron sooner. But what did you do with a strange wooden turtle? It's not made of gold and jade, can you use a wooden stick under your stomach as a gift for yourself?

Bai Dong took the wooden turtle with a smile, took out the 'divine iron' from the iron box and put it into the hollow turtle's belly, and then supported the wooden turtle on the round wooden stick, and buckled the tenon and tenon, only then did he hold the wooden turtle and the tray in the air, and let go of the other hand that held the turtle ~ head.

"The turtle ~ head moved, no, the turtle moved! Point to the south! ”

Bai Dong's hand just let go. The turtle lying on the wooden stick turned around, and only stopped when the turtle ~ head pointed south. Gongzishun did underground 'work' in his early years, and lived a life on the water, and developed a pair of 'divine eyes', according to modern standards, it is estimated that he has 2.0 vision, and he can be a pilot. And he has been a water bandit for a long time, and he is the most sensitive to the position, and he can see at a glance that the turtle ~ is facing the south!

Ou Yeliang stared at the turtle for a long time. When Bai Dong began to suspect that he was the legendary 'mung bean', this thing quickly rushed to Bai Dong with an arrow step. snatched the wooden turtle from his hand, and then ran around in the sword house, one moment in the north, one moment in the south, and in the blink of an eye, he tried the east and west sides, but no matter how he ran, the turtle would always spin in time, and the turtle ~ was always looking at the south!

Seeing this scene, Bai Dong also secretly breathed a sigh of relief, he also heard the teacher talk about the method of artificial magnets in middle school physics class, the principle is to use the earth's magnetic field to magnetize ordinary iron blocks; After the iron block is burned red, the temperature will be higher than the Curie point, and the magnetic domains in the iron sheet will disintegrate and become paramagnets, and after cooling, the magnetic domains will be re-formed, at this time, the iron will be pointed to the meridian position and the sub-position according to the direction of the earth's magnetic field, and under the action of the geomagnetic field, the rearranged magnetic domains in the iron will have directionality, so it can indicate the north and south.

In order to ensure that he does not miss a hand, Bai Dong also specially used an iron box to load the iron block, and then opened holes at both ends of the iron box and connected magnetic absorbing needles, so that the magnet created would be more sensitive and durable; Moreover, the magnetic field in ancient times is far stronger than that of later generations, and there is no interference from the magnetic field of various electrical appliances, the success rate will be higher.

"Amazing, it's amazing! Teacher, what method did you say Bai Zi used to make this turtle always look south? ”

Ma Qiao is a strong man with developed limbs, and his head is inevitably a little not bright enough, so he didn't ask Bai Dong at the first time, but asked his teacher and the old man, which made the son and the old man blush, touched his beard and said: "There must be a mystery of heaven and earth in this, and it must be an outsider."

Everyone listened to it, and what they said was equal to what they didn't say. Ou Yeliang held the wooden turtle in his arms like a treasure, and trotted to Bai Dong: "How did you do it, tell me quickly!" ”

The carthing's heart was beating wildly, and his breathing became short. He saw a huge business opportunity from this wooden turtle, this thing is worth a lot of money, and the Ou Ye family is going to send it?

"Slow, since Bai Zi has put forward conditions, then I should only be sued alone, and the rest of the people can't listen to it!"

Seeing Bai Dong open his mouth to speak, Ou Yeliang was suddenly anxious. There are so many people in the Sword House, how can you just talk about it? hurriedly stopped Bai Dong, and then looked at everyone with bad intentions.

Bai Dong frowned slightly, this kind of invention of the guide turtle is actually not an invention, it can only be regarded as a discovery, he has not had such a thick skin to apply for a patent from the Qin State; And considering the development of human science and technology, I have never thought about any technical barriers. However, Ou Yeliang is obviously determined to make money, if he says the mystery in public, this product may really regret not going to Qin State, or so, he will first fulfill his wish and get this greedy guy to Qin State first. If the Qin people want to dominate the world, they must have the advantage of a battle, and they can't do it without a great sword master like Ou Yeliang

At Bai Dong's request, the fleas left the sword house indignantly; Bai Dong smiled and glanced at Ou Yeliang, who was eager for knowledge, and said: "Actually, there is no bizarre technique, after refining iron like you, as long as you put this iron block in the meridian direction for a stick of incense, it will have the effect of indicating the direction."

"It's as simple as that?" Ou Yeliang frowned and thought for a long time: "But why is this?" ”

"Because we live in a world with a magical force called the magnetic field, which turns iron into blocks. The iron is then affected by the magnetic field. Thus indicating the north-south direction. Be sure to place it on the meridian though. Otherwise, it will not work. The results are the same without the iron box, but with this iron box, the success rate will be higher and the effect will be better."

"That is, you didn't do anything at all, so you tricked me into going to the Qin Kingdom? Baizi, I'm afraid this is a little unfair, isn't it? ”

"Really? But if I don't tell you the truth, I don't know how long it will take for you to find out on your own. Mr. Ouyang. Sometimes it's not easy to discover a secret, it takes wisdom, if you can't reach Minghui, even if you smelt iron and smelt swords all your life, you won't be able to make such a pointing to divine iron. And I still know a lot about similar discoveries, if Mr. Ouyang is willing to go to the Qin State to be the chief furnace of the Ordnance Division, you and I will naturally have many opportunities to learn in the future, such as whether it is possible to harden the soft ironmaking and make it sharper and more durable than bronze? Is it possible to refine a new metal? Let it go far beyond bronze and iron? Bronze and iron will lose their original luster over time, and iron will rust if not wiped often, can we refine a metal that will never lose its luster and will not rust? I don't believe Mr. Ouyeel would be uninterested in any of this. ”

"Sharper than bronze, never tarnishing, never rusting?"

Ou Yeliang looked blankly at Bai Dongbian Tian. After a long time, he took a deep breath, and his face was a little flushed: "I promise you to go to Lao Qin!" A must go. No one can stop it! ”

"Haha, I promise, if Mr. Ouye comes to Lao Qin, I and the gentleman will treat Mr. as a guest; In the future, the name of Mr. will spread all over the world, far to future generations, and even surpass the ancestors of the Ouye family! ”

Just like the mad scientists of later generations, once there is a better proprietor, better research conditions, and higher scientific research goals, the difference between countries and national feelings is nothing, not to mention that the Ou Yeliang family does not have much sense of belonging to the war-torn Yue country, so Ou Yeliang is just leaving, and there is no nostalgia for the Yue country.

Even the people belong to the Qin State, and the materials in this sword house naturally belong to Lao Qin, Ou Yeliang is very generous this time, not only Sang Wazi and Flea each got a sword that he refined with his own hands, but even Maqiao got a pair of iron flails.

This pair of flails is much better than the mace used by Ma Qiao before, the whole body is made of Ou Yeliang's quenched fine iron, the two hammer heads seem not big, but they are much heavier than the bronze of the same volume, and they can be touched into powder by gently waving them at any time. Ma Qiao excitedly played a set of flail methods, and the moves were wide open and closed, and he walked more than 30 rounds with Sang Wazi without falling behind; Of course, Sang Wazi also loves his straightforward personality, and cherishes the sword he just gets, and he doesn't use all his strength, but it can also be seen that this pair of flails is powerful.

With the guide turtle, Bai Dong's sailing plan was officially put on the agenda. Now it is only necessary to wait for the first fleet of ships to be built and the sailors to learn the basic theories before going to sea; Under Bai Dong's money offensive, the children of the public loser estimate that they will be able to build the required one main ship and three 'piglet boats' used to traffic the ancestors of the devil in two months, the problem is mainly in the training of sailors, ordinary sailors only need to carry out a series of water training, and they can use the guide turtle to identify the direction, and the roles of the sailor and the captain and mate who are responsible for steering and sailing need to learn to locate the latitude and longitude, identify the charts in combination with the latitude and longitude, and deal with emergencies at sea. The theoretical content is taught by the outstanding students of the academy brought by Bai Dong, and the practical content on the water is to ask Gongzi Shun, a water bandit leader who has been on the beach and is familiar with the nature of the sea, and there are also generals who are good at water warfare under Dr. Guiwei, and with their help, it is not difficult to train a sailor who can sail to the Japanese island.

The first batch of sailors was composed of some of the clansmen of the son and the old man, and the backbone was part of the old army of the Bai family and the subordinates of Gongzi Shun; In addition, there must also be a landing operation bullying the ancestors of the 'marines', Bai Dong is ready to wait for this sea route to be completely opened, and then gradually selected from the elite of Lao Qin, but now there is a lack of manpower, and Dr. Guiwei took the initiative to provide five hundred elite soldiers for the fleet.

These are all elite Vietnamese soldiers who have rich experience in water warfare and have undergone blood and fire training in the Vietnamese Civil War, Bai Dong naturally laughed at this, and by the way, donated tens of thousands of gold to the Vietnamese royal family, which is also a logical thing.

***

Standing on the port wharf, Bai Dong looked at the bags of grain and water being transported onto the four sea ships neatly arranged in the port, and he was a little irrepressible excited; If it weren't for Yingqu Liang's three flying eagle letters a day to urgently recruit him back to Lao Qin, I really wanted to personally participate in this voyage and be the first to set foot on that sinful land

However, with the steadiness of the third brother Yingquliang, he would send three urgent letters a day, and refused to reveal what was going on in the letter, but he was afraid that something big had happened, and Bai Dong could only suppress the urge to be Columbus in the pre-Qin era.

"Baizi, the grain and clear water have been prepared in double portions according to your requirements, enough to sail thousands of miles, but the cabin space is limited, and the remaining space is better to bring some live sheep and live pigs, and the brothers will be full when they go to sea, but you don't let you bring more meat and livestock, what do you do with a lot of fried and dried autumn woong and beans? Fried dried autumn woad is also eaten by people? If you eat too many beans, you will only fart, which is too uncomfortable."

Zi and the old man and Ma Qiao stood aside and looked at the sea, there seemed to be endless flaws, Gongzi Shun was nagging Bai Dong dissatisfied, this voyage, Zi and the old man are the captain, he is what Bai Dong said 'first mate', in this case, since the son and the old man just ask these miscellaneous things, he should be in charge, but this Bai Zi is so strong, he must bring the fried dried autumn siong and countless beans in the fleet, isn't this crazy, who will love to eat those things?

"When you get to the sea, you should eat more fried and dried autumn sapoo, soak the beans in water to sprout, and the stew tastes very good, and you have to eat it every day. Believe me, people who have been at sea for a long time can easily get a strange 'blood disease', and once they are infected, there is no cure! Eating these autumn sprouts and bean sprouts regularly can ensure that you will not get this kind of blood! ”

Even in the 21st century, scurvy should be prevented early, but it is difficult to cure, Europe in the Age of Discovery, I don't know how many sailors died of this disease because of a long-term lack of vitamins, Bai Dong wants to develop the Great Voyage, but not to the Chinese people to die collectively, so from the beginning the voyagers were required to insist on taking vegetables and bean sprouts.

Gongzi Shun glanced at the guide turtle erected on the bow of the boat, nodded and said, "Just listen to Bai Zi, I will eat dried autumn woad and bean sprouts as rice in the future." ”

Bai Dong glanced at him with a smile: "You don't need to eat too much, you will fart if you eat too many bean sprouts" (to be continued......)
