Tong Xiaowu has almost forgotten about the math problems in junior high school and high school, but she is still willing to give it a try.

So, she spent an afternoon and finally searched all her memories and brain cells to make this problem.

God knows, what was the expression of that Zhiminglin's son-in-law when he saw the answer?

He couldn't believe it and asked all the details of the question, including the algorithm of the circular area, the effect of the imaginary line, etc., etc., and so on, not even the decimal point.

So, Tong Xiaowu spent another day and a night explaining to him.

In the end, the other party was finally satisfied, not only answered Xuanyuan Yufeng's question, but also told all the details of the matter at that time, together with the evidence, in whose hands? Who's involved in this? It's all spoken.

That visit was a painful visit, and everything in the past was like a knife in Xuanyuan Yuchen's heart.

Although both sides got the answers they wanted, they were excited and happy, while Xuanyuan Yuchen was bitter and angry.

It turned out that the Jingbei Altar tragedy was a well-planned and premeditated plan, and the mastermind behind it was the current queen, Empress Rongzheng.

If the main reason is investigated, it is because the emperor passed the crown prince to Xuanyuan Yuchen, who was only two years old.

At that time, Rong Zheng was just a concubine, and she had a good relationship with Empress Qing'an, and her son was born two years early in Xuanyuan Yuchen, ranking as the second prince.

The eldest prince is frail and sickly, and his mother is the son of Qiandi, and his status is low, so he has no possibility of competing for the crown prince.

So if the next people are distinguished according to the eldest and youngest, Rong Zheng's son is the heir in line, but because of the identity of Empress Qing'an and the emperor's love, Xuanyuan Yuchen, who was only two years old at that time, was finally named the prince and lived in the East Palace.

But the good times didn't last long, at the sacrificial ceremony of the Jingbei Altar, Empress Rong Zheng contacted her mother's eldest brother, and actually colluded with the tribal leaders of the Northern Underworld to infiltrate Xuanyuan disguised as Han Chinese.

The capital is located in Jingzhou, the north of Jingzhou is Qinzhou, after Qinzhou is the North Hell, the difference between inside and outside is less than a thousand miles, the other party dressed as a Han Chinese, and ambushed around the altar early, plus the person in charge of the Imperial Forest Army at that time was Rongzheng's eldest brother.

For convenience, we have the right time, place and three winning factors,

After the two sides fight, it is clear who loses and who wins.

Because Xuanyuan Yuchen was the crown prince at the time, although he was only two years old, he had to participate in the occasion of the sacrifice ceremony, and Empress Qing'an was by his side at that time.

Suddenly in chaos, Empress Qing'an was assassinated in order to save her son, and the enemies of the North Underworld were also killed and wounded, and the rest of the people fled.

The prince was lost, the emperor was furious, and cut down the leaders of the Imperial Forest Army, and Rongzheng's eldest brother, in order to get rid of suspicion, actually chose to die on the altar directly, not only won a good reputation, but also picked their Rong family cleanly.

After that, the emperor sent down many officials and began various investigations.

But after so many years, this tragedy is like a grind, one will be pushed to Beiming, one will be pushed to Gong Dou, and one will be pushed to the local people.

No matter how you push it? The people who were sent down one after another, but none of them could have a reasonable explanation, and Rong Zheng did not fall down.

Later, when the emperor was seriously ill, Rong Zheng personally served, and for him he used to cut meat and stew soup, and later in an attack, she also blocked feather arrows for the emperor, so she almost lost her life.

Since then, as a concubine, she has finally left an immortal image in the emperor's heart, and finally got the position of queen.

At this time, even if anyone doubts her, even if the emperor has thought about whether the mastermind behind the scenes is her, it doesn't matter, after all, there is no real evidence.

The Rong family, the elder brother of the leader of the Imperial Forest Army, died but made her a queen, and at the same time, her son Tongdai also ascended to the position of prince, and the other brothers of the Rong family were blessed in the shade, and they were all promoted.

Now that the Rong family is in the capital, except for the royal family, they dare to say second, and no one dares to say first.

And above the court, there are more and more people on the side of the prince, and in the later period, several princes died, so that more people stand on the queen's side.

After 18 years, although the emperor has been sending people to investigate in secret, he is still covered with loess, and there is no clue.

And Empress Rongzheng's impatient assassination of Xuanyuan Yuchen made the parties have to be suspicious.

And this time, after getting Zhiminglin's answer, Xuanyuan Yuchen became more and more angry, "This hatred is not shared, I must make her pay." ”

"She killed your mother, if you stayed in the capital back then, I'm afraid that you would have been a pile of bones by now."

A child, without support, lives in the deep palace, whether it can last long, you can know it when you think about it.

It was also the mistake that made Old Man Feng think of his second son and the identity of the other party's wealth, so he became greedy and saved him.

It's a pity that the people of the Feng family don't know what to do, but if they treat him well and don't force him in their thinking, this life-saving grace alone is enough for the Feng family to be rich and noble for several generations.

It's a pity that the people's hearts are not enough to swallow the elephant, and the other party tried to kill him several times, and finally ended up sitting in the nine clans.

And Dani and her sister and brother were saved by Xuanyuan Yuchen, it can be regarded as Dani has front and back eyes, and she has been blessed, if she is also like those relatives of hers, I am afraid that the Feng family will not even have a bloodline left.

Tong Xiaowu still clearly remembers that the son of Zhiminglin once said that the evidence of the Jingbei tragedy was in the hands of Gamahan, the leader of the Xilin tribe in the Northern Underworld.

The other party can tell the human and material evidence, which shows the authenticity of this matter, and then talk about General Dingguo, Anguo Hou Anqing also once said that the mastermind behind the tragedy was Rong Zheng.

If it was really her, could she still let them go? If it was her, how could they just leave it at that?

Since what she cares about most is the position of the prince, then why can't they snatch the position of the prince back, if Xuanyuan Yuchen becomes the prince, who else can suppress them like this for no reason?

Besides, even if they don't fight with the queen's people, will they let them go? Think about the seriously ill eldest prince, think about the four princes and the five princes, their fates are already presented in front of you, do you need to think about it?

Instead of waiting for the other party to hit themselves, it is better for them to take the initiative.

And this treasure auction is an opportunity, and it can be regarded as a big gift from Tong Xiaowu to them, letting them know the power of the masses.

Here, Tong Xiaowu is wholeheartedly arranging the auction, and the queen has also been dispatched to fully monitor her actions.
