In order to obtain the manufacturing technology of artillery, the Roman emperor used money and noble status as temptations to let Zhen Xing's sailors stay in Rome and teach Rome how to make artillery.
These sailors risked their lives to come here just for money. Now the Roman emperor not only gave them money, but also gave them noble status. What else could the sailors say? Many of them immediately defected to the Roman emperor.
There are also some who have not taken refuge. Although they have such thoughts, they are reluctant to leave their families and resist the temptation!
Even if Zhen Xing knew about this, he had no choice but to bow his head under the roof. If his men did not join the Romans, he might be the one who stayed. At the same time, Zhen Xing had to teach the Romans about gunpowder.
formula, otherwise, he doesn't know if he can leave here!
After all, compared to the sailors, Zhen Xing had been taught by Xu Wei for many years. At this time, his depth and breadth of knowledge were not comparable to those of ordinary Roman scholars.
He can discuss mathematical knowledge such as geometric algebra with scholars in Rome, engineering projects with craftsmen, and military knowledge such as formations with generals. Daqian's civilization level is now one level higher than Rome's, not to mention Zhen Xing's
Xu Wei’s plug-in taught him. What Zhen Xing caused a sensation in the entire city of Rome was his discovery of lead poisoning among Roman nobles.
After more than a month of fermentation, Zhen Xing's reputation in the city of Rome was already great. At this time, a scholar who admired his knowledge gave him a bottle of wine. Originally, this was nothing, but Zhen Xing was surprised.
I discovered that this wine was actually bottled in lead bottles.
This shocked Zhen Xing and thought that the scholar wanted to kill him. He immediately found the Roman emperor and asked the Roman emperor to seek justice for him.
The Roman emperor asked the two sides to confront each other. Only then did Zhen Xing discover that the entire Roman Empire did not know that lead was a poisonous metal.
Then he suddenly realized that it was only in the past few years that Dagan people had this understanding, and it was still a matter of popular science in power.
At that time, Daqian wanted to build a canal system to transport mountain spring water to Daqian city as domestic water. In order to facilitate the construction, the craftsmen at that time found lead, an easily meltable metal, as water pipes. This was immediately stopped by Xu Wei, who
After reading thousands of books, how could I not know that lead was one of the murderers that led to the fall of the Roman Empire?
So he conducted experiments with rabbits and chickens, letting the people of Daqian see how the rabbits and chickens that ate lead skins were poisoned little by little. Only then did the concept of lead poisoning become widely known to the people of Daqian!
Obviously, the Romans don't know this yet, so Zhen Xing can only educate them on it himself.
The Roman emperor and scholars were horrified when they heard the news! They couldn't even believe it!
Lead is a very fine metal. It has abundant reserves and a low melting point. It is highly ductile and soft enough. It is very easy to refine and process. Its bluish-white luster is also very beautiful.
Moreover, there were abundant reserves of lead in Rome, so they widely used lead in all aspects of life - toys, statues, rings, coins, cosmetics, pigments and even as medicine for treating diseases. Various tableware, kitchen utensils or containers
They also used a large amount of lead materials. It can be said that they were exposed to this metal all the time in their lives, especially the water pipes in Rome were made of lead. If this were true, then the entire city of Rome would be in a state of lead poisoning.
.
Zhen Xing learned that there were a lot of lead items in the city of Rome, and even water was transported in lead pipes. He could only admire the Romans' ability to resist poison, and they were not poisoned to death!
But in order to prove his words, he also conducted experiments with rabbits and chickens, and this experiment caused a sensation throughout the city of Rome. The people of Rome were so concerned about whether they were poisoned that these experimental products were brought to the Roman Forum. Let everyone observe.
Then the Roman emperors, senators, scholars, and common people saw these experimental subjects weakening day by day, their eyes turning blood-red, and finally they died suddenly in less than a week!
When the last rabbit died, the whole city of Rome was in a state of shock. Everyone threw away anything related to lead in their homes, dug out lead pipes and threw them away. For a time, lead became something that everyone in Rome was shouting about!
After this incident, Zhen Xing became a hero of the Romans. At the same time, Zhen Xing's knowledge shocked the Romans. The Roman emperor recruited him and even used a honey trap to keep Zhen Xing in the Roman Empire. , to serve their own empire.
】
It's a pity that Zhen Xing has the pride of belonging to the Daqian people. Even though the Roman Empire is the most powerful country he has seen besides Daqian, he is still unwilling to stay in Rome.
After his intention was known to the Roman Emperor, although the Roman Emperor was not happy, he did not embarrass Zhen Xing. Firstly, Zhen Xing now has high prestige in the city of Rome. Secondly, for the Roman Emperor, the most important thing now is Open up business routes with Daqian and solve Rome's economic problems!
Of course, after Zhen Xing and the others stayed in Rome for several months, the Roman Emperor found that he could not persuade Zhen Xing to stay. He could only hand out a letter to Zhen Xing. He said it was for the Seris emperor, and at the same time he also He also expressed his desire to get through to the Seris country.
Zhen Xing had long wanted to leave the city of Rome, so naturally he immediately accepted the letter from the Roman emperor, saying that he would definitely deliver it!
In the end, Zhen Xing left Rome with his ship and continued to move towards Africa. However, their journey was not good. Rome was still civilized, but the places behind it were even worse than the New World, especially here. Malaria killed most of their few sailors here, so much so that Zhen Xing had to capture some savages here as a labor force to supplement his own manpower shortage.
In this way, they sailed tens of thousands of miles and finally returned to Tianzhu!
Zhen Xing was now dressed in rags, his hair and beard almost completely covering his face, his whole person was dark and unintentional like a savage, and his face was depressed.
But when he heard that Tianzhu was coming, he was shocked and said: "We have really arrived in Tianzhu? This won't be a desert island, right?"
"There can be no mistake. I have been to Tianzhu several times. There can be no mistake in calculating the latitude and longitude!" the astrologer said firmly!
At this time, the observing sailor shouted excitedly: "I saw the flag of the Daqian Navy. It's unmistakable. We have really arrived in Tianzhu! We are going home!"
"Go home!" These words brought tears to everyone's eyes. After more than three years, they were finally about to end this endless voyage.
