After Liang Yitan was poisoned, the biggest suspicion fell on Yang Huairen, and at this time, Lan Ruoxin jumped out to find out everything with him, and at the same time made Yang Huairen understand what happened.

Even so, Yang Huairen still has no conclusive evidence to expose Zhao Zonghui's true face.

Lan Ruoxin and Yang Huairen experienced the battle of Qingping Pass together, and under the outbreak of feelings, they confessed everything to Yang Huairen and handed over a letter handed over to her by Zhao Zonghui.

When Lan Ruoxin handed over the poison to the Khitan spies hidden in Huanzhou, he relied on this letter to confirm the identity of the other party.

Yang Huairen told him what happened and how he found the clues, and then found Zhao Zonghui, a big fish that was hidden deeply.

It was only when Lan Ruoxin's identity was hidden, only that he was a patriot in a gang, and he didn't want the Great Song Dynasty to fall for the treacherous tricks of the Khitans, and he couldn't bear to see the people of the Great Song Dynasty suffer misery, so he stole the letter proving that Zhao Zonghui had betrayed the country and handed it to Yang Huairen.

Zhao Xu was furious when he heard this, and ordered Zhou Fu to present a few letterheads to him for seeing.

When Zhao Xu saw the contents of the letterhead, he frowned and asked, "This...... Yang Huairen, how come these letters are all radicals of some words and a few sentences of poetry that are randomly pieced together? How can this prove that these letterheads are evidence of the communication between King Pu and Khitan spies? ”

Yang Huairen looked at Jian Zhoufu and the two prime ministers, and smiled without saying a word.

Jian Zhoufu leaned in and whispered to Zhao Xu, "Your Majesty, if these letterheads are written in an ordinary format, they can't prove anything, and it is precisely because Zhao Zonghui wrote in the encrypted format of the letter that it seems suspicious." ”

Zhao Xu suddenly realized, "You mean, the writing format of these letters is encrypted?" ”

"Yes."

Jian Zhoufu is a waiter in the Criminal Department, and he usually studies the text format of encryption and decryption, and he pointed to several confusing symbols on the letter and explained to Zhao Xu:

"Your Majesty, please see, these symbols actually express a kind of order rule, and the radicals, margins, or strokes that look like a few words are divided, and they are used to form the order of the words, and then read the order of seemingly unrelated phrases or verses below.

Each of these phrases or split verses corresponds to a meaning, such as 'spring breeze' representing this timing, and this 'cauldron' representing their plan.

As for the 'firewood', it represents the poison sent by Zhao Zonghui, and the 'fat sheep' represents the target of their conspiracy plan.

According to the order of the previous paragraph, the phrase "the firewood blown by the spring breeze is prosperous, and the fat sheep is put into the cauldron" seems to be a simple and vulgar verse, but the meaning is that the poison has been delivered, and the timing is just right, and the goal can be introduced into the plan. ”

"Oh? I remembered that my great-grandfather, Emperor Renzong, had ordered someone to compile the "General Essentials of the Martial Arts", which seemed to mention in this military book that when the army was fighting, it passed messages to each other, and in order to prevent it from being stolen by the enemy, the letters were encrypted by encryption. ”

"What the Holy One said is true."

Lu Dafang said, "Back then, Duke Xuanjing and Duke Wen Jian served the purpose of benevolence, collected and sorted out several generations of military books, and wrote the "General Essentials of the Martial Classics", which can be described as a collection of military books in the past dynasties.

The method of encrypting letters mentioned in the book, as mentioned by Jian Shilang, there are word splitting methods and substitution methods, so these letters should not be wrong according to Jian Shilang's interpretation. Just ......"

Zhao Xu immediately understood Lu Dafang's doubts, handed back the letterhead in his hand to Jian Zhoufu, and motioned for him to pass the letterhead to Lu Xianggong and ask him to re-identify it.

Lu Dafang took the letter from Jian Zhoufu's hand, read it carefully, and found that Jian Zhoufu's interpretation was not wrong, and what made him even more convinced was that the handwriting on the letter was Zhao Zonghui's undoubted, which also confirmed that Zhao Zonghui's betrayal of the country was exactly as Yang Huairen said, and the evidence was conclusive.

Lu Dafang nodded after reading it, and passed the letterhead to Fan Chunren. He first looked at Yang Huairen, then at Zhao Zonghui, and asked again with a heavy face, "Zhao Zonghui, now that the evidence is conclusive, what explanation do you have?" ”

"I ...... I ......"

Zhao Zonghui was speechless, his face was more ugly than dead, "I" for a long time, and then ashamedly took off his long-winged cage hat, put it on the side of his body, and bowed to the ground solemnly.

"Your Majesty, the minister is guilty, the minister is greedy for temporary interests, and he ignores the safety of the country, the minister deserves to die, please give the minister the death penalty!

It's just that Weichen's son and grandson don't know, and the top and bottom of Pu Wangfu, the guards and family members don't know about it, and Weichen begs His Majesty to forgive the people of Pu Wangfu for the sake of family affection. ”

How can it be said that people are dying, and their words are also good, Zhao Zonghui saw that his affairs were exposed, and he had no heart to quibble, and at the last moment, there was a trace of kindness in the deepest part of his heart, begging Zhao Xu to let go of his son, grandson and other family members for the sake of his relatives.

Zhao Xu sighed, as an emperor, he only now realized how difficult it was to really be an emperor.

Zhao Zonghui is a royal family surnamed Zhao, speaking of which is still his family, even he doesn't care about the country and the people of the Great Song Dynasty, he only covets the immediate interests, and conspires with foreigners to calculate the interests of the Great Song Dynasty, not to mention others?

He looked around at the civil and military officials in the hall, these people were in his heart, whether they were to the Empress Dowager Gao or to him, if they really wanted to distinguish it, they were not traitors to the loyalty of the Great Song Dynasty.

But don't these seemingly sanctimonious loyal ministers put their own personal interests above the interests of the country in private?

In order to be promoted, in order to make a fortune, they can say one thing today, and they can do another tomorrow. But when the Great Song Dynasty was facing a crisis, how many people could really stand up and give up everything they had to work for the Great Song Dynasty?

At this time, Zhao Xu looked at Yang Huairen's eyes again, and he was even more full of appreciation.

In Huanzhou, he led his generals to rush to Qingping Pass regardless of life and death, and took the initiative to participate in the desperate struggle, guarding not only a pass, but also the dignity of the Great Song Dynasty.

After that, the design defeated the Xia army, which made the government and the opposition excited. But such a truly loyal and patriotic person was recommended by the vast majority of people in the court to be tied up and handed over to the Western Xia people.

When his mother carried the coffin and knelt at the gate of the palace, no one in the court spoke for him, not even himself at that time.

And when he returned to Tokyo, he once again disregarded his personal safety and led troops to conflict with Pu Wangfu, and also fought for his own life to arrest Zhao Zonghui, the prince who had betrayed the country......
