Zhang Juzheng slowly put down his chopsticks and looked at Zhao Hao with a serious expression.

Qi Jiguang also regained his eagle-like gaze, and it was like a different person in an instant.

"Don't be nervous, it's not that someone is poisoning, it's that there is something wrong with the fish itself."

"What's wrong with this fish?" Zhang Juzheng's expression was slightly gloomy.

"Do you know how it was delivered?"

"I just said it, with an ice boat."

"When I was born in Jinling, I went to see how they kept it fresh." Zhao Hao said unhurriedly: "I found that in order to keep it fresh, it is necessary to pack the fish in a large box made of lead, and then fill the river with coagulated lard, and then freeze it layer by layer with ice cubes. ”

"Yes, that's right." Zhang Juzheng nodded and asked, "Is there any problem?" ”

"The problem is in the box made of lead," Zhao Hao explained, "There is a chemistry in science, which specializes in all kinds of materials. In chemistry, lead is referred to as a heavy metal. It is very dangerous to use lead boxes for food. ”

"Because of the free lead ions, it can contaminate the food. It can make people dizzy, fatigue, and loss of appetite; It can cause anemia in people, and in severe cases, it can cause toxic encephalopathy and make people crazy and die early. ”

"So serious?" Zhang Juzheng subconsciously touched his beard and said, "Don't you eat it for many years, and you don't feel anything?" ”

"It's too late to feel it, Xianggong." Zhao Hao sighed, this is not alarmist.

There is a consensus in the historiography that ancient Rome was destroyed by severe lead poisoning.

And various Ming notes say that Zhang Juzheng is a fan of anchovy and eats hundreds of them every year.

Therefore, many researchers in later generations believe that Zhang Juzheng's many rebellious actions in his later years and his early death may be related to the serious excess of blood lead in his body.

Of course, there is also a saying that points to Qi Jiguang......

Either way, Zhao Hao wants to avoid it as much as possible. Allowing Zhang Juzheng to live for an extra year is a great help to the Ming Dynasty and himself.

"The son of a daughter, he can't sit down." He gave up his hand and admonished: "Xianggong is the world, he should cherish this body for the sake of the Ming Dynasty, and he would rather believe that he has it than believe that he has not." ”

Qi Jiguang was very cautious, and when he heard this, he also nodded and agreed: "Yes, Xianggong, the taste of the fine-scale fish in Yongding River is not bad." Since Zhao Gongzi said so, there is really no need to take any more risks. ”

"Hmm." Zhang Juzheng nodded silently, reluctantly glanced at the Yangtze River Sanxian, and waved his hand to let people withdraw.

Zhao Hao asked him how much he had eaten in Beijing.

Fortunately, Zhang Juzheng was only a five-grade official during the Jiajing period, and the emperor's reward was not on his head at all. I can only try to make two of them every year, and I just try to try them.

Even if it was a sudden increase in the last year, because of Emperor Jiajing's new funeral, Longqing did not reward him lavishly, he only ate a dozen or so pieces.

In this way, it should not be a big problem.

He instructed Zhang Juzheng to eat garlic, milk and eggs, as well as apples, oranges, and kiwifruit...... These are all things that help to flush out lead poison from the body.

Zhang Juzheng wrote it down very cautiously, and arched his hand to Zhao Hao: "Thank you for reminding me, Bugu will not touch these distant tributes again in the future." ”

Zhao Hao breathed a sigh of relief, he was really worried that Zhang Juzheng didn't care and didn't listen to him at all.

Fortunately, Zhang Xianggong is still afraid of death.

Moreover, when Zhang Juzheng looked at the history books, he found that all the emperors who made alchemy and took medicine basically did not live long, or like the first emperor, they were crazy in their old age......

He had seen the case of the first emperor in the Tai Hospital, and knew that the symptoms of the first emperor were very similar to the lead poisoning that Zhao Hao said.

And lead and mercury are the two main drugs that all alchemists can't avoid when refining pills.

Thinking about it this way, it is a miracle that the first emperor took drugs day after day and lived to be sixty years old.

Of course, this is just speculation, but there is really no need to be reckless in such a life-threatening matter......

~~

After a while, the cook changed the table again.

But just now, everyone lost their appetite, so they still focused on talking.

During the banquet, Zhang Juzheng wanted to invite Zhao Hao to tutor his sons.

Zhao Hao hurriedly explained to him clearly, so as not to be considered by the idol as a deceitful and famous. "Don't hide it from Xianggong, science is not the study of imperial examinations. Later life is not long enough to be in the way of the imperial examination. ”

"Oh?" Zhang Juzheng and Qi Jiguang were a little surprised, it was hard to imagine that the teachers of the five Jinshi were not good at doing business.

"The disciples were originally relatively good in their careers, and they were promoted when they apprenticed to several teachers." Zhao Hao explained half-truthfully: "It is because science helps train thinking and strengthen logic that it helps them improve their performance." ”

Well. It's not because of this son, who has the skill of 100% betting on the problem.

"That's it......" Zhang Juzheng did not look down on Zhao Hao because of this, but became more and more happy: "Okay, very good." How do you say that? Oh yes, science, it's about seeking truth from facts. ”

Zhao Hao's face was not red, and he said secretly, but unfortunately scientists can lie.

However, Zhang Juzheng still hopes that Zhao Hao can take the time to teach them science......

It is estimated that it is because Zhao Hao said that science can improve the results of the imperial examination, right?

Zhao Hao couldn't shirk it, so he agreed with Zhang Xianghe to come out every five days in the afternoon to give a science lesson to his sons.

For this reason, Zhang Juzheng also took the trouble to let his five sons come out and meet the newly invited Xixi.

It's a pity that he didn't mention how to count it, and Zhao Hao didn't dare to ask.

Hey, it's a blessing to be able to serve idols, and there's no money to make.

The five boys heard that they would not have to read with Mr. Cheng every five days in the future, and their mouths were grinning at the back of their heads.

I heard that I was learning science from Zhao Hao, and even the most calm cultivator couldn't help but cheer.

Because those little science toys are so much fun......

They naively think that studying science is also a happy thing.

Hehe......

~~

After lunch, Zhao Hao and Qi Jiguang said goodbye with interest.

When parting, Zhang Juzheng deliberately pulled Zhao Hao aside and whispered to him: "The day after tomorrow, the Hanlin Academy will be selected, your three disciples, don't have too much hope." ”

"Oh?" Zhao Hao knew it in his heart and pretended to be surprised. "They are all in the top 36 of the second class."

"That's just a conventional rule, and now that Your Majesty has broken the rules of the palace test, you can't blame Elder Xu Ge for breaking the rules for selecting Jishi." Zhang Juzheng sighed and introduced the situation of the palace examination to Zhao Hao in a few words.

Hearing this, Zhao Hao was stunned for a moment, and said in his heart that Emperor Longqing was not a little bee? How can it sting?

"Bugu can help you keep a spot at most." Zhang Juzheng asked in a low voice, "Do you think which one is on?" ”

"I'm going to have to go back and ask." Zhao Hao said in a low voice: "Their fate should be decided by themselves. ”

"It's fine." Zhang Juzheng nodded and said: "Tomorrow will not be on duty, and it will be decided to inform You Qi." ”

"Thank you." Zhao Hao gave a deep salute.

"It's about promoting science." Zhang Juzheng said lightly.

Zhao Hao was stunned for a moment when he heard this, but he never expected that a lecture in Lingji Palace would actually hook a golden alliance for his own door......
