Everyone Loves Rong Shizi [Transmigration Book]

Rong Xi has learned from Cheng Hao that Si Nan has been handed down in ancient times and has evolved into a water compass.

Water compass, as the name suggests, the magnetic needle floats on the water in the center of the disc, indicating the direction by magnetic force.

However, the water compass has disadvantages. If the boat is sailing on the sea and is bumped by wind and waves, the water in the center of the disc will shake accordingly, and it will be difficult for the floating needle to maintain the correct direction.

Rong Xi borrowed the method of later generations to improve the water compass.

A small hole is opened at the center of gravity of the magnetic needle, and a shaft is supported below it, so that the magnetic needle will not lose its orientation due to water shaking.

This is the dry compass.

However, the dry compass cannot completely avoid the turbulence of navigation.

But Rong Xi never underestimated the wisdom of ancient craftsmen.

In the former dynasty, there were skillful craftsmen who made the "quilt incense burner".This incense burner has a unique structure, no matter how it is rolled, the burner mouth remains horizontal and will not leak.

Just because there is a gimbal in the furnace.

If the gimbal can be applied to the compass, the Paul disc will not be disturbed by external force.

After some research and development, Rong Xi and Cheng Hao seriously made the Changping Compass.

The reason why he asked Jin Jili was to know whether the secret method of the Baisha Kingdom was more practical than the Changping compass.

One is for the sake of the lives of soldiers, and the other is pure curiosity.

After returning home, the four of them went to the research room.

Rong Xi took out the Changping compass, Jin Jili observed it for a while, and said with admiration: "The ingenuity is astonishing."

Although he praised so much, he was still confident on his face.

Rong Xi laughed and said, "I wonder if I can see the compass of your country?"

Jin Jili didn't keep his secrets anymore, he took out a copper disc, and put a pointer on the disc, with a small hole at each end of the pointer.

"Astrolabe?" Rong Xi blurted out.

In his previous world, the astrolabe was used by foreign countries in ancient times, and it could measure the angle of stars, so it was called "astrolabe".

The stars include the sun, the moon and the stars.

Jin Jili was extremely surprised, "Da Lang actually knew this thing?"

After he sold fish to make money, he asked craftsmen to help him make astrolabes. As far as he knew, no one in Wei Dynasty knew the uses of astrolabes.

"I heard about it from a merchant." Rong Xi replied calmly.

The astrolabe can measure time, latitude and longitude, etc. It is indeed more advanced, but there are still drawbacks.

"The astrolabe is very useful, but if it is rainy, how can you measure it?"

Jin Jili smiled helplessly: "So whether you can survive or not depends on God's will."

When he was speaking, Wei Zhan had already grabbed the astrolabe and was playing with it to study it. After not understanding the principle, he asked, "How can we tell the direction?"

Jin Jili didn't hide any more, after all Wei Zhan will go to sea together next year, as the chief general, he must learn, so he took him to the courtyard and taught him the method patiently.

After Wei Zhan learned it, he frowned and thought for a while, and said, "What Rong Dalang said just now has some truth. If it is rainy and the sun, moon and stars are not visible, how can we tell the direction? Why don't you bring a compass."

He felt that the Changping compass could ensure the direction of navigation.

Jin Jili glanced at him, and this stupid man actually thought the same as himself.

"Dalang, I do need a compass."

The combination of the two is double protection.

Rong Xi has no reason to refuse. He developed the Changping compass for navigation.

"I'll ask the craftsman to make more, and I'll give it to you at that time."

Jin Jili nodded gratefully and said, "Thank you."

"No need, you have taught the shipbuilding department the art of shipbuilding, and you already owe both." Rong Xi said sincerely.

This is the words of the heart.

Although Rong Xi is not good at shipbuilding, he also knows that there is a huge gap between river boats and sea boats.There are many rivers in Dawei, and boats often rely on the power of paddles and poles.

However, Baisha Kingdom is good at building sea-going ships, and has already used sails to ride on the wind.

How to control the sails, which knowledge is also very deep.

What Jin Jili taught is not just the sails.Sea-going ships are also very particular about the shape of ships. If it weren't for Jin Jili's teachings, the shipping department would not be able to build many sea-going ships in a short period of time.

The Shipbuilding Department is affiliated to the imperial court, and Jin Jili has been very sincere in exchanging shipbuilding skills for military strength.

Time flies, and the end of the year is approaching.

After the Armament Supervision Workshop uses machine tools to manufacture the barrels, not only the efficiency is increased several times, but also the barrels can withstand fire and the impact force of the gunpowder is far greater than before.

Craftsmen in various workshops used this machine tool principle to create other machine tools for use elsewhere.

For example, stone crushers and heavy hammers use mechanical power to drop from high altitudes, repeatedly hitting ore, etc., to turn them into fine powder, which saves a lot of time and effort compared to craftsmen beating them by themselves.

Qin Ke presented a secret performance to report to the emperor.

After reading it, the emperor was very happy, and wrote back a letter asking when he would return to Beijing.

When Rong Xi stepped into the bedroom after taking a bath, he saw Qin Ke Zhan Xin frowned.

"What happened?"

Qin Ke raised his head and said, "I need to go back to Beijing."

"When will we leave?" Rong Xi asked while wiping his hair.

He had expected this matter a long time ago. Qin Ke only worked in Mengshan. In the eyes of others, Rong Zhai was just a temporary residence for him, not a family house.

"Ten days later."

Rong Xi looked calm, sat on the chair, and asked again: "When will you return?"

"I will definitely return before the Shangyuan Festival." Qin Ke suddenly smiled.

Rong Xi's heart skipped a beat, so he changed the subject and said, "Bring me some presents back to Beijing."

As for who to give it to, the two knew it well.

The next day, when Rong Xi came back from the prison, he had just drank a cup of hot tea when he heard Liu He report: "Mr. Lang, Guo Silang wants to see you."

Guo Silang is Guo Zigui.

Rong Xi was curious, so he said, "Let him in."

After a while, Guo Zigui stepped into the study, his cheeks were flushed with cold, his voice trembled a little, but his eyes were extremely bright.

"Lang Jun."

Rong Xi asked with a gentle smile, "Zigui, why are you looking for me?"

Guo Zigui showed a worried face, and then mustered up his courage to say: "Mr. Lang, I heard that Mr. Jin Lang wants to return to his homeland, can I go with him?"

Since Rong Xi was unable to explain to Qin Ke and others last time, he compiled basic textbooks to teach students in his free time, just like the courses related to elementary education in later generations.

The students are very thirsty for knowledge, although Guo Zigui's temperament is outrageous, but his mind is quite flexible, otherwise he would not be able to compete with Guo Yao for the top spot.

After he learned the textbook, he was full of thirst for the outside world.

Guo Yao asked Rong Mo for arithmetic in his spare time, and Guo Zigui learned Baisha Mandarin from Jin Jili when he had time.

Rong Xi saw that he was full of expectations, and said solemnly: "Auspicious' journey back to the country is extremely dangerous, and after returning to the country, there will be dangers everywhere. At that time, the soldiers will not be able to take care of themselves, let alone protect you. Do you really want to go?"

Guo Zigui nodded firmly, "Mr. Jin, Mr. Jin Lang has already told me that I know this is dangerous, but I still want to go."

He knew that his actions had really failed the kindness of Mr. Lang, but the thoughts in his heart were too strong, which bothered him all night and made him unable to sleep.

"Why are you going?" Rong Xi asked expressionlessly.

He would rather take great risks than travel across the ocean to a foreign land.

Guo Zigui said sincerely: "Lang Jun, you said that beyond Linxi there is Mount Meng, beyond Mount Meng there is Qingzhou, beyond Qingzhou is Great Wei, and beyond Great Wei is vast and infinite, I want to see what is vast and infinite. "

"Even if you are swept into the deep sea by wind and waves halfway, will you not hesitate?" Rong Xi admired his fearlessness, but logically he did not want him to take risks.

Jin Jili and King Shun still have a mission, but Guo Zigui may die due to the bad weather at sea before he reaches Baisha Kingdom just because of his vigor and frail body.

Knowing that Rong Xi was worried about him, Guo Zigui felt both guilty and moved, and said, "Mr. Lang, you said at the beginning that the Great Wei knew very little about oceans and foreign countries, just like a craftsman building a car behind closed doors, and will eventually lag behind others."

Rong Xi waited for his next words.

"Lang Jun, if you allow me to go with me, I will definitely record the scenes along the way. Even if I die unfortunately, I will leave some experience behind."

He made himself a mission upon himself.

The boy is only 15 years old, although his body is thin, but he is full of energy. Saying these words has exhausted most of his courage.

Rong Xi was silent for a long time, and said in Guo Zigui's apprehensive eyes: "I don't limit your freedom, but you are young and not physically strong, so you can't do this."

"Lang Jun, I have practiced martial arts with brother Zishi for several months, and I have also asked Jin Langjun how to swim. You don't have to worry." Guo Zigui was quite firm.

Rong Xi didn't supervise the daily life of the students, so he didn't know that Guo Zigui made such efforts secretly.

He sighed in his heart, he couldn't bear to destroy people's dreams in the end, so he said earnestly: "You can go with auspiciousness, but you have to come back alive."

Guo Zigui's eyes lit up, and he said gratefully, "Thank you, sir!"

"Thank me for what?" Rong Xi shook his head and said with a gentle smile, "It's great that you have such a desire for knowledge, please take care."

Guo Zigui responded excitedly.

A few days later, Qin Ke returned to Beijing, and Chen Chuangu walked with him.Rong Xi's interest was rather low, so he devoted himself to the research room.

After Qin Ke returned to Beijing, he went straight to Changxinhou's mansion.

Princess Mingyi looked behind him and was disappointed to see that Chen Chuangu was the only one.

"Da Lang didn't return with you?"

Qin Ke said with a smile: "Mother, now that there is no Rong Mansion in Shengjing, how can he return to Beijing? Don't worry, Dalang also misses you, so let me bring some things for you to enjoy."

After he finished speaking, he took out some exquisite objects from the cloth wrapping, all of them were things that Princess Mingyi had never seen before, and they were in line with Princess Mingyi's wishes, quite novel.

Princess Mingyi smiled happily, "Not bad."

After New Year's Eve, Qin Ke was thinking about how to say goodbye to his parents when he was called by Princess Mingyi.

"When will you leave for Linxi?" She glanced at Qin Ke lightly, as if dissatisfied with him.

Qin Ke didn't understand what she meant, and was thinking about answering when Princess Mingyi grabbed his arm.

"Do you know that the Empress Dowager has always wanted to marry Da Lang?" She hated iron and steel, "If I hadn't seized the opportunity, Da Lang might be married by now. You are my son, and I can still prevent you forever, but Da Lang's marriage , I can’t do it either.”

Qin Ke frowned.

"It's been half a month since you left Linxi, why haven't you set off to go back?" Princess Mingyi worried for him.

Qin Ke: "..." He has only been back to Beijing for two days!

"I'll be leaving tomorrow, thank you for your reminder, Aunt."

Marriage is really difficult.

The Empress Dowager likes to be a matchmaker. Fortunately, A Niang was clever at the beginning, so she managed to get away with this matter.

It's better to return to Linxi quickly and discuss with Lan Zhi.

Early the next morning, Qin Ke rushed straight to Linxi.

Chen Chuangu complained a lot on the way, Qin was too impatient, and he was awakened by him while he was still asleep, it was really painful.

Linxi Rong Zhai.

Liu Zishi was building a snowman and having a snowball fight with his students. Rong Xi saw that he was quite childish, so he joined in and played with them.

Suddenly, a ball of cold snow smashed into the back of Rong Xi's neck, his whole body trembled and he shivered.

Rong Xi hurriedly shook off the snowball, and turned to look.

Wei Zhan was baring his teeth and laughing wildly, beckoning him provocatively.

With a sneer, he squeezed out a huge snow ball and smashed it directly.

However, Wei Zhan's figure was flexible, he easily dodged, and then fought back. Rong Xi was hit by him several times, but he couldn't fight back, quite aggrieved.

Jin Jili found out that Wei Zhan was "bullying" Rong Xi, so he naturally wanted to seek justice for Rong Xi, so he fought back with Rong Xi.

Two-on-one, and Jin Jili's accuracy is excellent, Wei Zhan will inevitably get hit a few times, but he plays more and more vigorously.

After a while, there was a sound of horseshoes coming from far and near.Rong Xi suddenly felt something, and turned around to look.

Qin Ke came on a steed, with a magnificent appearance, which was even more dazzling than the sun behind him.

He stared at Rong Xi closely, got off his horse neatly, and was about to approach, but saw a snow ball flying across the sky, approaching his chest.

Qin Ke didn't notice it for a while, but was hit straight.

"Hahaha," Wei Zhan's laughter almost broke through the sky, "Qin Ke, hit me again!"

Another snowball hit.

Rong Xi was startled, and before he had time to think, he blocked Qin Ke, and the snow ball hit his neck directly.

Qin Ke's face darkened, he carefully took the snow ball out of Rong Xi's collar, and said, "Stand here obediently, and I will avenge you."

Chen Chuangu: "..." Your Highness King Shun, take care!

So next, Wei Zhan was double abused by Qin Ke and Jin Jili. The two were extremely powerful in combat.

But for a moment, his head and body were covered in slush, and he was so distressed.

Rong Xi stood beside him quietly, staring at Qin Ke's figure, his mood suddenly brightened.
