"It's all!" Zhao Huan smiled and haha, a little nervous, waiting for the system's inspection results.

The consequence of an emperor without children is that he has no national foundation, which means that the country and the country are in turmoil. Every time the imperial power is handed over, it will be accompanied by bloody storms.

The most obvious one is Zhao Zhen, the Emperor Renzong of Song. During his reign, this emperor was kind-hearted, not luxurious, diligent and loving the people. Six of the Eight Great Masters of the Tang and Song Dynasties were between the Renzong Dynasty. During the middle of the reign, the first battle between Song and Xia broke out.

Three battles between Sanchuankou, Haoshuichuan and Dingchuanzhai were all very exciting. If the Liao Kingdom had not taken the opportunity to go south, Xixia would have been destroyed by Zhao Zhen in just three years.

Unfortunately, when the Liao Kingdom went south to build momentum for the Western Xia, the Song Dynasty, which could not start a war on both sides, could only negotiate peace between the two sides.

All three sons died prematurely, and after the death of Emperor Renzong of Song, the tug-of-war between the old and new parties in the court officially began.

Without the foundation of the country, there is no confidence to speak.

Even if Zheng Wangzhi took the letter and asked him to inherit the throne to Zhao Dalian, Zhao Huan had no descendants and had a weaker confidence in speaking.

"I don't know what the logic of these court officials are. When the Eight Gates entered Beijing, Chen'er was only seven years old. I have all taken the position of crown prince, so why are you still holding on to me?" Zhao Huan flipped the letter leisurely, waiting for the systematic examination of his body.

【There is good news and bad news, which one do you want to listen to?】

Um?!

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

[The reason why the Emperor of the Song Dynasty had not given birth to a prince for a long time has been found.]

[Kaifeng, the capital of the Song Dynasty, was only a prefecture in the Tang Dynasty. The Kaifeng Palace was originally the residence of the Jiedushi. At the beginning of its construction, in order to prevent mosquitoes and ants from eating, a large amount of mercury, sulfur and other substances were sprinkled under the palace, and all of these were the causes of destroying the body's functions.]

[The prince who grew up living in the Bianjing Palace has long taken heavy metal water sources rich in lead and tribute, which has caused heavy metal poisoning to a certain extent. After growing up, most of these princes are weak, have fewer offspring, and have difficulty giving birth.]

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

[Song Huizong Zhao Ji did not live in the palace since he was a child. He moved into the palace only after his brother Song Zhezong died. After a few years, he built the garden of Yanfu Palace, built Wansui Mountain, and built the Genyue Palace.]

Zhao Huan understood the reason. In ancient times, most of the golden elixirs were fired by mercury, and after taking them, they could become immortals.

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

Zhao Huan sat upright and asked, "What about the bad news?"

[The bad news is that the system can only repair the body of the host, but the host's offspring still lives in an environment surrounded by heavy metals. The water consumed and heavy metals consumed are more heavy metals. The physical deficiency caused by heavy metal poisoning will be the norm for offspring.]

【The horrible amount of heavy metal poisoning may lead to the fall of the empire.】

[The demise of the ancient Roman Empire is widely rumored that the tens of kilometers of elevated water supply pipes in the city of Rome used lead water pipes, which led to the weakness of the Romans and was defeated by the Germans, the slaves of 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 deposited on the surface of the lead water pipe to protect it. The continuous flow of the water source will cause minimal lead pollution.]

[However, heavy metal poisoning in the Roman Empire was common. The main reason for lead pollution is that the lead water pipes produce a large amount of toxic steam during the production process.]

[In life, the popularity of wealthy people in lead products and the long-term use of wine vessels and cooking utensils for lead products is an important reason for lead poisoning.]

[The reason why the Romans are fond of lead is lead acetate. Lead acetate containers will react with the acetic acid in wine, producing lead acetate and a sweet taste.]

[And what more, the Romans would put sour wine in a lead pot and steam it until it was sticky. The wine that was originally sour wine turned into sweet syrup. The raw materials were simple and easy to obtain, and turned waste into treasure, so that lead acetate was used in large quantities in beverages, pastries, and dishes.]

[In later generations, the steaming and cooking utensils with inferior spicy strips were mostly made of lead. Many children who like to eat spicy strips showed signs of lead poisoning.]

【Guess if your dessert has lead acetate?】

Zhao Huan suddenly shuddered. Although lead acetate tastes sweet, it is not sweet to eat it, it is obviously taking poison.

Fortunately, the Song Dynasty has a lot of land and wealth, and there are many methods to make sugar. Sucrose cubes and brown sugar are quicker and sweeter. I don’t like the sweetness of lead acetate.

"That is to say, Chen'er..." Zhao Huan asked with a sigh. He had a system that could repair the heavy metal poisoning caused by his growth, but Zhao Chen did not have his own system.

Zhao Chen, who grew up in the Bianjing Palace, had lost the sky without being full of wings.

[Zhao Chen is growing up. If he moves out of the palace, there is a 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..."

【cannot.】

The Great Emperor system simply and roughly interrupted Zhao Huan's delusion.

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

The first thing that the court discussed at that time was that Yue Fei sent troops to Wuhai, and Li Gang didn't even ask.

"Yanjing is here and after it is built, you have to move the capital." Zhao Huan whispered to himself. Originally, the move to the capital in Yanjing was under Zhao Huan's plan, and now we just need to speed up.

"It's better to write down the production method of lead acetate. What if it can be used in the future?" Zhao Huan always felt that lead acetate was of great use.

For example, make a large amount of lead products and ship them to the Jin Dynasty for sale?

The Jin Kingdom did not have so much sugar to eat. The Jin people who had two meals a day did not have so many natural sweets to eat.

Humans are sugar-loving.

This desire from the mouth is the most difficult to resist. Many people can't control their mouths. Before opening the snack bag, don't they all swear that this is the last bag?

"Is this a bad deed too much?" Zhao Huan felt a little guilty when he wrote the letter and was about to call Zhao Ying to take it away.

After all, there are countless Han people living on the lands of Fuyu Mansion, Huanglong Mansion, and Huining Mansion. The lands of these three mansions are now from the Jin people, but in the future they are from the Song Dynasty.

Such a trick of cutting off children and grandchildren may lay hidden dangers for your future rule.

"Forget it, it's passed on to Japan? That's better. Emperor He Feiyu resumed the government and specially gave a set of wine vessels. It was very popular and sweet, which was quite strange." After thinking carefully, Zhao Huan decided to throw it to Japan to try the power of this move.
