"Xu Fu?"

The official of the building ship at the news closure point was quite surprised, why did this sorcerer, who should have been wanted, appear here in a grand manner?

But those who are well-informed know that Xu Fu has been exonerated from the crime: last year, not long after the Zhutian rebellion was put down, when the imperial court was settling accounts after the autumn, Linzi and Jibei Juncheng submitted evidence that the magicians might have participated in the rebellion, and this group immediately turned into street rats, and everyone shouted and beat them.

At the same time, Xu Fu, who had disappeared for half a year, was found in the dungeon of a small island off the coast of Qingdao by Gongao, who had gone out to sea to patrol......

Xu Fu was also bitter in his heart, he was locked up by the black man for more than half a year, and he didn't torture indiscriminately, just let him be alone, he couldn't even see the sun, and came to see him every three or five times, and asked him to confess the black material of Lu Ao, Han Zhong and other magicians.

He didn't say it at first, but then he couldn't stand it, so he confided one after another.

"You know?" Hefu asked him.

"Know...... Informed. ”

Heifu said with a smile at the time: "If you don't report it, you still want to deceive Your Majesty with Lu and Han, it's really a capital crime, fortunately, I let someone intercept you in Langya, otherwise, you will have no way to live." ”

After that, Heifu left Xu Fu and came to see him for four consecutive months, Xu Fu had no one to talk to for more than 100 days, and the old man who delivered the food was also a mute, and he wanted to die.

When Heifu came back, he just said lightly that Zhutian had been pacified by himself, and then asked Xu Fu to draw a map of Jiaoliao.

Xu Fu still wanted to hide it, because he felt that if he knew everything, Heifu would soon no longer need him, and he would kill people.

But after looking at the first chart he had presented, Hefu only smiled lightly, picked up the charcoal next to him, and sketched it on the paper.

After a while, a map of Jiaodong, Liaodong, and the Korean Peninsula appeared on it.

After Xu Fu saw it, he was also shocked, the general direction of those coastlines was no different from what he remembered! What's even more amazing is that Heifu can also draw the coast that Xu Fu has never visited, and even in the southeast of the Korean Peninsula, a huge island has been added, pointing to it and jokingly:

"Xu Fu, Xu Fu, you want Your Majesty to give you a boy and a girl, and the place you want to go to will not be this...... What do you call this, Dongying? Fuso? Dwarf? The Land of the Rising Sun? ”

It doesn't matter what it's called, Xu Fu was almost scared to death, he thought that this was a little secret that he had pondered by himself, but it was ruthlessly revealed by Heifu, how did he know?

Xu Fu couldn't figure it out, he just thought it was a god, and he was so impressed that he didn't dare to hide in front of Heifu anymore.

He didn't know that this was when Heifu was in junior high school in his previous life, and he had made a meritorious contribution to the map of China that had been hung on the wall of the classroom for many years.

After bluffing Xu Fu and making him obey his words, Heifu told Xu Fu in high spirits that the collusion of the warlock with Zhutian had been exposed, and the group was completely cold, and Xu Fu was tragically angered and became a wanted criminal.

Xu Fu was a little desperate, could it be that a person as smart as him would have to be a prisoner for the rest of his life?

Heifu didn't speak at the time, Xu Fu didn't wake up until he heard half a ring, Heifu hinted so much, it was nothing more than telling him: You only have one chance left, and that is to stand up and expose Lu and Han!

Xu Fu was willing to cooperate, and after being brought back to Jimo, Heifu interrogated him with Juncheng. According to the script provided by Heifu, Xu Fu claimed that he had suddenly disappeared and did not go to the meeting of Chengshanjiao, not deliberately deceiving the king, but was shocked to hear that the scholar Han Zhong and others had lured the emperor to go to sea and wanted to plot wrongdoing.

"I wanted to denounce it, but I was discovered by Lu and Han's subordinates, brutally abducted, and thrown in a dungeon on a nameless island, and I was able to get out recently.

Heifu County Guard attached great importance to this matter and immediately sent Xu Fu to Qin Shi Huang.

After no longer believing in the sorcerer's nonsense, how could the emperor deign to see him? Everything was handed over to Tingwei Ye Teng for trial.

Xu Fu found that all his retreats were blocked, from escort to interrogation, it was all Heifu's people who were handling it, even if he arrived at the emperor's palace, he was also Heifu's father-in-law, Tingwei Ye Teng came to interrogate him, as long as he said the wrong word, the other party had a way to let him die.

What's the use of exposing Heifu even if he suddenly turns back? Heifu is in chaos, he is the chief of the seal, and his grace is flourishing, and the nonsense of a wanted criminal cannot cause damage to him, but will kill himself.

Xu Fu is a self-loving and life-loving person, and he knows that the most important thing he should do is to listen to Heifu's words and completely draw a line with the magician......

So his testimony became the last straw that brought down the magician, and Qin Shi Huang was furious and killed hundreds of people in total.

The unlucky Hou Sheng was tragically killed just because he "didn't know", but Xu Fu, as the first accuser, can be pardoned according to the law.

But Xu Fu was still not free, and afterwards, Heifu also asked that although Xu Fu was a magician, he never dared to deceive the emperor, and he was extremely familiar with maritime affairs, so he could let him serve in Jiaodong, and Qin Shi Huang allowed him to play.

At the beginning of this year, Xu Fu returned to Jiaodong and worked under the county guard, but he was extremely low-key and rarely haunted.

But Xu Fu didn't expect that after returning to Jiaodong, the errand given to him by Heifu was actually a management warlock......

After the pit warlocks, this group has disappeared, except for Jiaodong, which is the monks who previously helped Heifu find gold mines and improve salt drying techniques, and they were spared because of their merits in the imperial court.

But after this scare, the relationship between the sorcerer and the black man has changed dramatically compared to before, the past was full of hostility, but now they regard the black man as a thigh, once the black man is no longer protected, they can be arrested and killed at any time.

Heifu divided the remaining dozen or so magicians into two groups to learn "ancestral stove to things", that is, to play dansha to refine mercury, gold and iron to refine each other as a group, and secretly developed a project in Qingdao. He loves to seek immortals overseas, has taken a boat to sea many times, and is familiar with wind and waves and hydrology.

The final shape of the chart was drawn by Xu Fu with the second group of people, and it is not an exaggeration to say that he drew it.

Today, Heifu brought Xu Fu to Yantai Port, and the intention is also obvious: Heifu wants to lead the cross-sea grain this time, and deliberately let Xu Fu pretend to refute the plan proposed by Ren Huan!

As a person who has been traveling in this sea area for 20 years, if you are familiar with Shaohai and Donghai, everyone present together can't catch up with him, right?

After deciding on it, Xu Fu began his performance.

He paced to the center of the hall, waved at Ren Huan and the officials of the building, and then pointed to the location of Liaonan on the map and said:

"Lieutenant Ren, you just said that the boat from Lushun to Mazishui is extremely slow, like a boat against the current, it takes seven or eight days, can you know why?"

……

"Ocean currents?"

Ren Huan and the officials of the building boat listened to this unfamiliar term that popped out of Xu Fu's mouth, and they were a little confused.

"Yes, ocean currents."

"The rivers have flows, and so do the seas! Those who go to sea all the year round can know that the same ship, the same cargo, the same calm waves, from Yantai to Chengshanjiao, the journey is time-saving, only one day, and the return time is laborious, it takes one and a half days. ”

And what caused this situation is Xu Fu's so-called "ocean current", those who follow it are like going down the river on a big river, and those who are against it are like sailing against the current, and it is strange if they are not slow.

When he said this, it was in line with the common sense of Ren Huan and the officials of the building, but most of them were from the land of Chu Yue, they were familiar with the rivers and lakes, and they really didn't know Xu Fu's temperament about the sea.

Seeing that everyone no longer despised him, Xu Fu, a magician who had been out of the sea for half his life, used charcoal to draw a line along the sea as if he was lecturing, starting from the mouth of the Mazishui (Yalu River), and stopped at Lushun, marking an arrow, indicating that it was from northeast to southwest.

"There are ocean currents along the coast of Jiaodong, and there are also in southern Liaoning, which is also unfortunate, and the opposite direction of grain transportation, so it takes time to go from Lushun to Manbanhan, and it is labor-saving when returning!"

"I see."

Everyone bowed their heads, and Xu Fu said this thoroughly, he really solved an unsolved mystery.

Heifu sat in the hall and let Xu Fu explain the various "ocean currents" along the Jiaoliao coast, Xu Fu has some ability, and has gone to sea many times, he has long known that this kind of thing exists, and secretly summarized the law, but it was Heifu who gave it a name.

The roots of the two coastal currents Xu Fu mentioned are both the "Yellow Sea Warm Current", which is a branch of the "Kuroshio", the world's second largest ocean current.

The warm current of the Yellow Sea flows northward along the west bank of the Korean Peninsula, and near the Yalu River, due to the action of the Liaodong Peninsula, it turns southwestward, and under the action of the current of the Yalu River, it becomes stronger and rushes directly into the Bohai Bay!

This warm current will go around the coast of Bohai Bay, bringing heat and making the "Jieshi", or Qinhuangdao, an ice-free port, and then flowing out from the south side of the Bohai Sea. In the vicinity of Yantai in Jiaodong, it received fresh water from Laizhou Bay, turned into a coastal current of the Yellow Sea, bypassed Chengshanjiao, and continued to flow to the Langya area......

This is the circulation of ocean currents in the Bohai Sea and the Yellow Sea, and it is also the root cause of the early emergence of the Jieshi-Zhifu-Langya route.

If you understand this, you will be able to make the most of the currents.

Xu Fudao: "It's summer now, and the weak current in southern Liaoning is enough to make it difficult for boats to sail, and in autumn and winter, the current is twice as strong!" At that time, it will be really difficult to transport grain from Jiaodong to full sweat through Lushun! A round trip, I'm afraid it will take a whole month! ”

Ren Huan and the officials of the building and the boat groaned, if what Xu Fu said was true, then their grain transportation strategy could be reluctantly accepted in the summer, but once it was autumn and winter, it would be difficult.

"But if you go the other way, set sail directly from Chengshanjiao, arrive at the coast of North Korea, and then go north to Manbanhan, the ocean current along the coast of North Korea is from south to north, so that you can avoid the countercurrent, and go along the current on the return trip, you can get twice the result with half the effort, saving a lot of time!"

(There is a mistake in the previous text, the easternmost boundary of the Qin Dynasty is Manfan Khan, and the column mouth is still in the south, which should be the port of Jizi Joseon)

If you go with it, you will be fast, and if you go against it, everyone understands this truth, and everyone was gradually persuaded by Xu Fu, but there was still a problem in front of them.

"I've heard that the direct voyage from Chengshanjiao to North Korea is a full 400 miles, and the boat has to travel for four or five days......

Under Ren Huan's subordinates, the most experienced officer of the building boat looked embarrassed, shook his head and said: "I have also asked many old Yanqi boatmen, they have been out to sea countless times, but they dare not take this waterway. ”

For this era, there were very few ocean voyages off the coast, first of all, the sea was unpredictable, the sails of this era were still primitive, and they could not make good use of crosswinds, so they had to go downwind, and if there was no wind, they had to rely on oars to row.

To make matters worse, the loss of land markers also makes the course of the ships problematic, and on daytime and clear nights, the sun, moon and stars can be relied on to judge the direction of the wind, but on cloudy and cloudy nights, the fleet becomes headless flies and falls into a trance......

Among the Yan Qi Fang Warlocks, there are many people who have tried to sail, but most of them have seriously deviated from the course, and the ships with bad luck have been destroyed and killed.

"That's because they are unwise and can't observe the direction of the wind."

Xu Fu didn't think so, as a person who dared to instigate the emperor to go to sea, and even took thousands of people to sail to foreign lands in history, he naturally had a few brushes.

Xu Fu glanced back at Heifu, saw the master nodding, and continued: "I have spent ten years studying the direction of the wind, and I have gained a little, and now the wind is mostly blowing from east to west, and it is a little difficult to sail far, but once it is autumn, there is heaven to help it!" ”

"God forbid?"

Everyone frowned: "What do you mean by this?" ”

Xu Fu replaced it with chalk, and on the chart, in addition to the black currents, he added some small white arrows, which were either from north to south, or from south to north, or circling......

"It's ......"

The generals who have been working hard at sea all the year round, how can they be unfamiliar with this thing?

Xu Fu pressed the chalk: "Monsoon!" ”

This is the new name given to this special wind, Xu Fu thinks it is very realistic, the monsoon, the wind that changes with the season!

"Xu Fu is right."

Heifu also got up and clapped his hands for the crowd to look at him.

"With the help of this wind, the building ship sails away, crosses thousands of miles of sea frontiers, and conquers overseas countries, which is as easy as a snap!"
