"Neatly!" Zhao Huan laughed and laughed, slightly nervous, waiting for the results of the system's inspection.

The consequence of the emperor having no heirs is that he has no national capital, which means that the country is in turmoil, and every time the imperial power is handed over, it will be accompanied by bloody storms.

The most obvious is Song Renzong Zhao Zhen, this emperor during the reign, the temperament is lenient, not extravagant, diligent and love the people, six of the eight families of the Tang and Song dynasties are between the Renzong Dynasty, and in the middle of his reign, the first Song-Xia War broke out.

Sanchuankou, Haoshuichuan, Dingchuanzhai three wars, all fought impressively, if it were not for the Liao State to take the opportunity to go south, Xixia is afraid that it will be destroyed by Zhao Zhen after only three years of existence.

It's a pity that at that time, the Liao State went south to build a platform for the Western Xia, and the Great Song Dynasty, which could not start a war on two fronts, could only negotiate peace on both sides.

The birth of the three sons all died, and after the death of Song Renzong, the tug-of-war between the old and new parties in the court was officially launched.

Without the national foundation, there is no confidence to speak.

Even if Zheng Wangzhi took a zizi to paste his face and let him inherit the throne to Zhao Dayi, Zhao Huan had no heirs, and his confidence in speaking was a little weaker.

"I don't know what kind of logic these courtiers are, when Bamen entered Beijing, Chen Er was seven years old, and I took the position of crown prince, why did I still hold on to it." Zhao Huan flipped the notebook leisurely, waiting for the systematic examination of his body.

[There is good news and bad news, which one do you want to hear?] 】

Well?!

Zhao Huan looked at the subtitles reminded by the system, frowned and said, "Good news." ”

[The reason why the Great Song Emperor did not give birth to a prince for a long time was found. 】

[Kaifeng, the capital of the Great Song Dynasty, was only a state city in the Tang Dynasty, and the Kaifeng Imperial Palace was originally the residence of the Jiedu Envoy, at the beginning of the construction, in order to prevent mosquitoes and ants, a large number of mercury, sulfur and other things were sprinkled under the palace, and all this was the cause of the destruction of body functions. 】

[The princes who grew up living in the Bianjing Imperial Palace have taken heavy metal sources such as lead and tribute for a long time, resulting in a certain degree of heavy metal poisoning. 】

"Didn't Zhao Ji give birth to so much?" Zhao Huan asked with a frown.

[Song Huizong Zhao Ji did not live in the palace since he was a child, after his brother Song Zhezong died, he moved into the palace, and within a few years, he repaired the garden of Yanfu Palace, built Long Live Mountain, and built Genyue Palace. 】

Zhao Huan understood the reason, most of the ancient golden pills were fired with mercury, and after taking them, they could be feathered into immortals.

This is the ancient perception of mercury, and even Tang Taizong did not escape this fate.

Zhao Huan sat up straight and asked, "What about the bad news?" ”

[The bad news is that the system can only repair the host's body, but the host's offspring still live in an environment surrounded by heavy metals, and they eat more water and heavy metals, and the body weakness and illness caused by heavy metal poisoning will be the norm for the offspring.] 】

[The horror of heavy metal poisoning may lead to the fall of the empire.] 】

[The fall of the ancient Roman Empire is rumored to be due to the use of lead water pipes in the elevated water pipelines of dozens of kilometers in the Roman city, which caused the Romans to be weak and defeated by the Germanic people who were slaves in the past. 】

[Lead water pipe is not a storage system, the water source in the water pipe flows for a long time, and a layer of calcium carbonate will be precipitated on the surface of the lead water pipe to protect, and the continuous flow of water will cause lead pollution, which is minimal. 】

[However, the heavy metal poisoning in the Roman Empire was widespread. The main cause of lead contamination is that lead water pipes produce a large amount of toxic steam during the production process. 】

[In life, the pursuit of lead products by the wealthy, and the long-term use of lead wine and cooking utensils are important causes of lead poisoning. 】

[The reason why the Romans were addicted to lead was lead acetate. Lead containers react with acetic acid in the wine to produce lead acetate, which has a sweet taste. 】

[What's more, the Romans would put the sour wine into a lead pot and boil it until it was viscous, and the original sour wine turned into a sweet syrup, and the raw materials were simple and easy to obtain, turning waste into treasure, so that lead acetate was widely used in beverages, pastries, and dishes. 】

[In later generations, most of the cooking utensils of inferior spicy strips were made of lead, and many children who liked to eat spicy strips had signs of lead poisoning. 】

[Guess if you have lead acetate in your dessert?] 】

Zhao Huan shuddered violently, although lead acetate is sweet, but where is this sweet, it is clearly poisoning.

Thanks to the great Song Dynasty, there are more ways to make sugar, and sucrose cubes and brown sugar are faster and sweeter. I can't look at the sweetness of lead acetate.

"In other words, Chen Er......" Zhao Huan asked with a sigh. He has his own system to repair the heavy metal poisoning caused by the growth of this body, but Zhao Chen does not have his own system.

Zhao Chen, who grew up in the Bianjing Imperial Palace, has lost the sky in his fledgling.

[Zhao Chen is growing his body, if he moves out of the palace, there is no possibility that heavy metal poisoning will be relieved. 】

Zhao Huan looked at the system's reminder silently, and finally asked with a little unwillingness: "Can you ......?"

[No, you can't.] 】

The Great Emperor system simply and rudely interrupted Zhao Huan's delusions.

"Salted fish." Zhao Huan picked up the notebook at hand, this was the second thing he discussed with Li Gang a few days ago, to set up another palace in Yanjing.

At that time, the first thing in the court discussion was that Yue Fei sent troops to Wuhai, and Li Gang didn't even ask.

"Yanjing is here, and after it is built, the capital has to be moved." Zhao Huan muttered to himself in a low voice, originally Yanjing's relocation of the capital was in Zhao Huan's plan, but now he just needs to speed up.

"It's better to write down the way lead acetate is made, in case you can use it in the future?" Zhao Huan always felt that this lead acetate was of great use.

For example, make a large number of lead products and ship them to the gold country for sale?

Jin Guo doesn't have so much sugar to eat, and the Jin people who eat two meals a day don't have so many natural sweets to eat.

Humans are addicted to sugar.

This kind of desire from the mouth and stomach is the most difficult to resist, how many people can't control their mouths, before opening the snack bag, don't they all swear, this is the last bag?

"Isn't this too damaging to yin morality?" When Zhao Huan wrote the notebook and was about to call Zhao Ying to take it, he was a little weak-hearted.

After all, there are countless Han people living in the land of Fuyu Mansion, Huanglong Mansion, and Huining Mansion, and these three places are now Jin, but the future is the Great Song Dynasty.

Such a shady trick of cutting off children and grandchildren is likely to lay a hidden danger for his future rule.

"Or forget it, pass it on to the Wa Kingdom? In this way, He Feiyu reinstated the emperor and gave a set of wine utensils, which were prosperous and sweet for a long time, which was quite strange. After thinking about it carefully, Zhao Huan decided to throw it to the Wa Kingdom to try the power of this trick.

The king of the flying feather of the Wa Kingdom did not know that when people sit at home, lead comes from the sky.
