Tang Jian, the secretary of the household department, was the founding father of the Tang Dynasty, and he also made great contributions in the war against the Turks.

Although it was not the main force of the Tang Army, it also made important contributions to Li Yun's northward crusade and ensured the supply of grain and grass in the rear.

"Are you saying that the next one to be killed is Tang Jian's son?" Li Chengqian said.

Chai Shao nodded and said: "In that tragedy, Tang Jian contributed a lot, and he will inevitably die, and Li Yun will not let him go."

"But what about the charges?"

Princess Gaoyang and Fang Yiai are careless about human life, Cheng Chumo is intentional homicide, Chai Lingwu is corrupt and enclosed land, if there is no suitable reason to kill people, it is easy to attract the attention of the court.

"There are no charges to fabricate charges." Chai Shao said.

"Does he Li Yun really dare to do this?" Li Chengqian said with some incredulity that the people he killed before were indeed charged, but Tang Jian's son Tang Songling had no bad habits.

"Have you forgotten what happened when he first met you?" Chai Shao reminded.

How could Li Chengqian forget? Li Yun almost didn't beat Li Chengqian to death, and it was so hateful that he broke one of his legs, and the brutality of his behavior was outrageous.

"It seems that the prince has not forgotten, there is no Li Yun in this world, he doesn't dare to do it." Chai Shao said.

Li Chengqian's face was gloomy, his fists were clenched, it was his sad past, and he still felt ashamed when he thought about it now.

"Someone is coming, hurry up and inform Tang Jian." Li Chengqian said.

However......

Li Chengqian was still a step late, and when he sent someone back from Tang Jian's mansion, it was already night, and after the subordinate hurriedly came back, he told him a shocking news.

"Prince, Lord Tang is dead." The servant said.

Li Chengqian stood up suddenly, stepped forward and grabbed his subordinate by the collar, and asked angrily: "You say it again, who died?!"

"Don ...... Master Tang Jian died in the study. The servant said in fear.

Li Chengqian couldn't believe his ears, thinking it was an auditory hallucination, and he was still talking about him in the morning, and he died at night?

"Tell me, what's going on?"

"According to the examination, Lord Tang ate two kinds of food that were rushed, which caused food poisoning and died." The servant said.

As we have learned, there are two kinds of food that will kill people if they are eaten off, such as pork and chrysanthemums, and so on.

"Nonsense, how can two kinds of food be mixed to kill people?" Li Chengqian couldn't understand the nonsense of this Arabian Nights.

But if you say so, you can't be wrong.

"Where's the cook in the Tang Mansion?"

"He also died, and after learning that Tang Jian had eaten his own food and died, he hanged himself in fear."

After Li Chengqian listened, he pushed his subordinates away, punched the table fiercely, looked viciously in the direction of Yunwangfu, and said angrily: "Li Yun, you are ruthless enough."

There is no need to think about this matter, it must have been done by Li Yun, but Li Yun did everything without leakage and thought about it so carefully.

And he did things that they didn't expect, they all thought that Li Yun would attack Tang Songling, but he assassinated Tang Jian, and for a while people couldn't figure out what Li Yun wanted to do.

Because Li Yun doesn't play cards according to the routine at all.

……

And Chai Shao came to the prince's mansion overnight, obviously he already knew about Tang Jian's killing.

Li Chengqian was frowning in the study, while Chai Shao's face was full of fear.

At first, they only thought that Li Yun had killed their children, but they didn't expect Li Yun to start acting against the perpetrators now, which meant that Chai Shao was very likely to be assassinated.

He didn't want to die yet.

"I don't want to say it, this palace knows what you want to say, there is no evidence in this matter, and there is no way to prove that Li Yun is the mastermind behind it." Li Chengqian said.

"Are you just sitting still?" Chai Shao is unwilling, his son is dead, is his life also threatened, he wants to fight back.

"Or else? What else can I do? Li Chengqian said helplessly.

"This matter must be told to Your Majesty, even if there is no evidence, it can make Your Majesty suspicious, this Li Yun is really cunning, and he must not be allowed to go unpunished."

Li Chengqian thought for a while, felt that what he said was reasonable, and after telling Li Shimin about this, let Li Shimin be mentally prepared, if he continued to die, it would definitely arouse his vigilance.

At that time, it will not be so simple for Li Yunzai to kill people.

"Good! Without further ado, let's enter the palace. ”

Li Chengqian hurriedly put on the official palace and went to the imperial city, and Chai Shao followed.

……

After entering the palace, Li Shimin announced that the two of them entered the palace, and at this time Li Shimin was still correcting the folds, as a good monarch who is diligent and loves the people, he will naturally not waste time.

After the two of them saluted, Li Shimin asked, "You two came here late at night, what is the urgency?"

"Father, you already know about Lord Tang Jian." Li Chengqian said.

"Someone has already reported to me, why do you still have something to say?"

"Erchen thinks that Lord Tang died strangely, a big living person died like this, should this matter be thoroughly investigated." Li Chengqian said.

Li Shimin said: "Prince, you are my son, I know what you are thinking, just say what you have to say, there is no one else here."

When King Tang said this, Li Chengqian also said bluntly: "Erchen thinks that Lord Tang was assassinated, and the murderer is King Yun."

"You said Tang Jian was killed by King Yun? Is there any evidence? Li Shimin asked rhetorically.

"Erchen has no evidence, but Erchen is sure that this matter must be inseparable from King Yun."

So, after Li Chengqian told Li Shimin the reason for the incident, he thought that he would show a surprised expression, but in exchange for not surprise, but his calm face.

"I know about this, so you can step down." Li Shimin said.

"Father, King Yun is taking revenge, please ask Father Emperor to investigate." Li Chengqian said.

And Li Shimin still said lightly: "Stand down."

"Father, you have to investigate."

"I'll tell you to step down!!" Suddenly, Li Shimin's whole body changed dramatically, and he shouted loudly.

For some reason, Li Shimin changed so much that Li Chengqian and Chai Shao were puzzled about what was going on.

It stands to reason that Li Shimin would loudly reprimand Li Yuncai, but the result turned out to be that Li Chengqian was scolded.

"The retainers retired." Li Chengqian said incomprehensibly.

Before they retreated, Li Shimin said, "I don't want the fourth person to know about tonight's events, have you understood?"

Li Chengqian and Chai Shao nodded.

After the two retreated, Li Shimin said behind the bookshelf, "Come out."

At this time, a person slowly walked out from behind the bookshelf, and this person was none other than Li Yun.

"Do you hear that?"

"Clearly." Li Yun said.
