Zhu Youxiao informed Ye Xianggao of Zhang Gui's statement that the cinnabar in the Forbidden City was poisonous.

Ye Xianggao soon realized that if what Zhang Gui said was true, then the emperor would have to move out of the Forbidden City, and this meant that the etiquette system of the Son of Heaven who should live in the world and not be tampered with would be destroyed!

And once the ritual system is destroyed, the scholars can no longer control the emperor with the ritual system!

Therefore, Ye Xianggao immediately vetoed: "Your Majesty, what Uncle Guo said is not enough to believe!" Cinnabar is a thing to ward off evil spirits, and it will not be filled with poisonous gases. ”

Wang An also helped: "Emperor, cinnabar is indeed a thing to ward off evil spirits, and what Uncle Guo said is indeed a bit absurd. ”

Another cabinet minister, Liu Yixian, even directly impeached Zhang Gui: "Your Majesty, Uncle Guo is deliberately misleading you to disrupt the court etiquette system, with ill intentions, please punish Your Majesty severely!" ”

"Your Majesty, the minister is not lying in vain, the cinnabar in the Forbidden City is indeed poisonous."

Zhang Gui had already come to the imperial front by order at this time, and heard the words of Ye Xianggao.

If it weren't for the Hakka treatment, he really didn't remember a research document he had seen in his previous life.

And that information mentioned that the newly built buildings in the Forbidden City would produce toxic gases due to the smearing of large amounts of cinnabar.

It is also because of this that the emperors of the Qing Dynasty in history lived a long life before the Old Summer Palace was burned, because they all lived in the Old Summer Palace, and their heirs were not cut off, but since the Old Summer Palace was burned and the emperor began to live back in the Forbidden City, since Tongzhi, these Qing Dynasty emperors have no heirs.

Of course, this is just one way of saying it.

Not necessarily exactly.

But what Zhang Gui can be sure of is that the cinnabar used in the Forbidden City is indeed poisonous, especially when it has just been repaired.

Of course, most buildings emit various toxic gases when they are just repaired, such as mercury vapor, formaldehyde, benzene and so on.

Unfortunately, the current imperial palace, with the three major halls of the main reconstruction project is underway, and the Qianqing Palace and Kunning Palace have only been repainted for a short time.

Therefore, in order for the emperor of Tianqi to be able to serve for a long time, at least his future nephew will not die early due to the harm of these poisonous gases, and then affect his future interests, Zhang Gui knows that he must now raise the problem of cinnabar poisoning.

"Your Majesty, Uncle Guo, this is absolutely nonsense! Cinnabar wards off evil spirits, everyone knows it, how can it be poisonous?! ”

Liu Yixiao immediately refuted.

"Fuck your mother."

"Do you understand science?"

Zhang Gui glanced at Liu Yixiu, scolded two sentences in his heart, and then said to Tianqi: "Your Majesty only needs the quasi-minister to do two experiments to prove that what the minister said is true." ”

Seeing that Zhang Gui's tone was so determined, Tianqi also believed it a little, and said, "It's okay to try, what are you going to do?" ”

Zhang Gui said: "Your Majesty, as long as the minister does this, the minister will go back to get the equipment and materials, and please also ask Your Majesty to send Gonggong Wei to help the minister go to get it together." ”

"Accurate!"

Apocalypse replied.

"Your Majesty! If Uncle Guo does not succeed in proving that the palace building is poisonous, please behead Uncle Guo! ”

Liu Yixiao suddenly proposed again.

"Why do you have to do that?"

Apocalypse asked.

Liu Yixiao replied: "Because Uncle Guo's move is ill-intentioned, and there is a suspicion of confusing the monarch and disorderly etiquette, once it is not severely punished, I am afraid that everyone will imitate this behavior in the future to disrupt the etiquette system of the world!" If you don't punish it, I'm afraid the world will be in chaos! ”

Tianqi looked at Ye Xianggao again and asked, "Yuanfu, what do you think?" ”

Ye Xianggao smiled and said: "If Your Majesty really wants to protect the uncle of the whole country, you shouldn't let him do this, in the opinion of the minister, the poison of cinnabar is just nonsense, once the uncle really wants to do this, even if Your Majesty doesn't kill him, the world will not tolerate him." ”

Zhang Gui glanced at Ye Xianggao: "What Yuan Fu said about the people of the world refers to the people of the world, when will the people of the world be able to represent the people of the world?" Obviously, it is Your Majesty who can represent the people of the world, if Your Majesty can tolerate the ministers, the people of the world will naturally tolerate the ministers! ”

"Shi is the head of the four people!"

Liu Yixian wanted to refute Zhang Gui's words.

But Ye Xianggao quietly pulled Liu Yixiao's shirt.

Liu Yixiao didn't say anything more.

And Tianqi only looked at Wei Zhongxian at this time: "Wei Zhongxian, you accompany Uncle Guo on a trip." ”

"Yes!"

After the order, Tianqi said: "Everything will wait for Uncle Guo's proof first." ”

Zhang Gui took Wei Zhongxian back to the house first.

The mansion of Zhang Gui's family is the mansion given by the Emperor of the Apocalypse, not far from the palace.

Therefore, soon, Zhang Gui brought experimental equipment and materials.

Zhang Gui first asked for an order to go to the palace wall to get some cinnabar, and then used a homemade sodium sulfide solution to dissolve the main ingredient in cinnabar, mercury sulfide.

In this era, there were already caustic soda and sulfur, and Zhang Gui had already prepared a sodium sulfide solution with these substances, the purpose of which was to enter the palace now to dissolve the mercury sulfide in cinnabar.

After dissolving the cinnabar, Zhang Gui divided the cinnabar solution into two cups.

He first broke an egg and began to drip egg whites into a glass of cinnabar solution, stirring.

Soon, Apocalypse and his ministers discovered that a white solid appeared in the liquid.

"Your Majesty, please see, these egg whites are like being burned with oil when they encounter cinnabar, solidified and deformed, which shows that the toxicity of this cinnabar can denature and inactivate egg whites."

As he spoke, Zhang Gui used a syringe to take half a tube from another cup of cinnabar solution without egg white, and then injected it into the live rats he brought.

It didn't take long for the rat to fall to the ground and not move.

Zhang Gui continued: "Your Majesty, please see, the poison of this cinnabar can also poison the rat directly, and the key minister only beat the rat to half a pipe, but how much cinnabar is smeared in the palace city?" When washed by rainwater, it dissolves into water vapor and then enters the human body, and people stay in this environment, like this rat every day being poured with cinnabar poison. ”

"I don't live here anymore!"

Apocalypse immediately replied.

"Your Majesty! Unlike humans and rats, cinnabar can only spoil eggs and rats, and is harmless to people! Please Your Majesty don't believe Uncle Guo's fallacy! ”

Liu Yixian said.

Zhang Gui argued on the basis of reason: "Your Majesty, if Elder Liu Ge still thinks that cinnabar is harmless to people, please ask Your Majesty to give him a drink to prove his words." ”

Tianqi looked at Liu Yixiao coldly: "Accurate!" ”

"This ......"

Liu Yixian was shocked.

"Give Liu Qing a glass of cinnabar water!"

Apocalypse commanded.

Wang An did not respond, and gave Wei Zhongxian and other eunuchs present, asking them not to obey the order.

Apocalypse therefore looked at Wang An coldly: "Wang An, didn't you hear what I said?!" ”

Wang An knelt down indifferently and said, "The emperor thinks twice!" If this water is not poisonous, it is fine, but if it is really poisonous, it will undoubtedly kill the ministers, the emperor! ”

Zhang Gui said: "He himself said that it is harmless to people!" ”

Apocalypse also followed: "That's right! I now want you to do my will! ”

Wang An knew that at this time, he couldn't let Ye Xiang's high-ranking ministers down, so he shouted again: "Emperor! The old slave really can't obey his fate! ”

Ye Xianggao, Liu Yixian, and Han Ying looked at each other and smiled, and looked approvingly at Wang An.

Tianqi looked at Wang An in surprise, clenched his fists, gritted his teeth and asked, "Wang An, do you know what you're doing?!" ”

Wang An said: "Please take back your life!" ”

Zhang Gui glanced at Wei Zhongxian, walked over, and asked in a low voice, "How long do you have to wait!" If you don't take action, I will let Your Majesty find someone else to do this, Wang Tiqian and Liu Ruoyu of the celebrant eunuch, I am not only a few eunuchs in the Ming Dynasty. ”

Wei Zhongxian glanced at Zhang Gui in surprise, and then made up his mind, walked quickly, and prostrate in front of the apocalypse: "Emperor, the slave is willing to obey the order!" ”

Tianqi looked at Wei Zhongxian and nodded: "It's still reliable for your own family!" ”

Wang An looked at Wei Zhongxian unexpectedly, and was furious in his heart: "Okay, you Wei Zhongxian, you can be the opposite food of the guest family, it is all the opportunity given to you by the ancestor of our family, you dare to betray our family!" ”

Zhang Gui handed a cup of cinnabar solution to Wei Zhongxian at this time: "Father-in-law Wei, please wait for Liu Ge Lao to drink." ”

Wei Zhongxian took the cinnabar solution and walked over to Liu Yixian.

Seeing this, Liu Yixiao immediately changed his words and arched his hand: "Your Majesty! Chen thinks that there is no need to try again! The safety of the monarch comes first, and even the slightest risk to the safety of the Holy Communion cannot be allowed! Now that Uncle Guo has proved that cinnabar may endanger His Majesty's holy body, His Majesty and the nobles of the harem should move to another place! ”
