Reborn as a concubine's sister, the eldest lady went crazy

When she arrived at the North Mountain where Ying Er was buried, she saw that there was no tombstone or grave, and she could barely tell that the land was newly turned.

"here?"

"Yes, right here."

“Why not erect a monument?”

"Our Shadow Guards' rules are that we don't build graves or erect tombstones. We are nameless during life and leave no trace after death." Ying Wu followed Xu Yixing today. There was no sense of sadness when he said this, as if the person who died was a person who had nothing to do with him.

"This rule is sick."

"I'm also afraid that if I had an enemy during my lifetime, my grave might be dug up after my death. You don't have to come here anymore. If someone is waiting here and someone is plotting to implicate you, that would be bad."

"Doesn't that mean he will have to stay here alone from now on, with no family, friends or relatives to visit him?"

"Do you care about this?"

After Xu Yixing died, except for the day she found her body and buried it, she herself never went to the grave again, let alone someone else who was completely independent of her in this world.

"Okay, I won't come here anymore. Siwen, take out the things. We'll need to take them away later. Don't miss anything. Someone you've met is buried here. Don't think about him anymore, but don't forget him either."

"Ah?" Si Wen knew that there was a big change in the capital yesterday. Although she was in the shop, she saw all the waves of soldiers and fire signals.

It turned out that yesterday there was also a person who was related to me but not so related. He died quietly in the black smoke without leaving a trace.

Si Wen knelt down, took out the items in the basket one by one, kowtowed, and put them back. The three of them went down the mountain as if they had never been there that day.

When I returned home, I naturally saw the letter that Ah Da had waited all morning to hand over to me.

"Did your master ask you to come?"

"That's right. Your Highness knows that you, Madam, are concerned about the follow-up of yesterday's incident, so he specially wrote this letter last night. You will know the whole story at a glance." General A handed over the letter with a "sincere" smile on his face, which he had learned from Lu Anyuan.

Xu Yixing found it funny and took it with one hand, mocking it at the same time: "Your master is really smart. He didn't come to tell me in person that he was doing this kind of thing. Does he really intend to never have any contact with me again? If so, you should tell him to give me a divorce letter as soon as possible, so that we don't have to worry!"

"This!" A Da's mind was filled with lawsuits. Didn't you drive His Highness away? How come it became the case that our His Highness didn't come?

A Da was still waiting for Xu Yixing's next words, but she saw Si Qin standing behind her, winking at her and saying something.

"Ah! I will ask my prince to come over and explain it to you in person!"

Watching Ada running away, Xu Yixing burned the letter in his hand with a candle. It was really boring for the whole family to still be doing these things!

"He has a high level of understanding."

Not long after, Lu Anyuan walked in with happy steps, and even knocked on the door a few times before sitting down next to Yixing, smiling: "I heard that Madam is looking for me? What's the matter? Tell me..."

"If you don't want to tell me, leave now!"

“Tell me, tell me!” Lu Anyuan sighed painfully. He still couldn’t beat Yixing.

After dismissing the attendants, he continued, "The note yesterday was written by my second brother. He held my fourth brother hostage, and then set up a gunpowder and poisonous smoke trap in his house, dispersed all the people in his house, and then led me there. His purpose was to kill my fourth brother and me."

"The Second Prince and the Fourth Prince have teamed up?" This was Xu Yixing's first thought, and it was also human nature. If they hadn't teamed up, how could the imperial prisoner who had been sought for so long have appeared in the Fourth Prince's place? How did they set up this scheme?

"I thought so too, but Fourth Brother said at the time that he didn't know about it. He said Second Brother had been staying in his house for ten days without anyone noticing, and only showed up yesterday and forced him to go to the courtyard where the trap had been set up long ago."

"This is outrageous."

"Indeed, but even if they joined forces, judging from what happened yesterday, there must have been a disagreement between the two of them, or he was deceived by my second brother and fell into the trap."

Xu Yixing shook his head. This was obviously not right. He needed more information to analyze it. "Yesterday, Ying Er broke the mechanism of the Fourth Prince's Mansion, so it wasn't there that it exploded. Then why did you look so gray when you came back yesterday?"

"Yes, it was Prince Cheng's Mansion. After escaping from the Bamboo Forest Pavilion, I concluded that my second brother would enter the palace, so I led people all the way to the palace gate. Who knew it was not there, but there was a burst of black smoke coming out of Prince Cheng's Mansion, so I rushed over. There is a secret passage under my uncle's study, and my second brother was found dead there."

Xu Yixing reported: "We went to Prince Cheng's Mansion... Then the secret passage leads to the Imperial Palace?"

"Yes." Lu Anyuan stretched out his hand to pull Yixing's hand, but it was ruthlessly opened. He could only smile awkwardly and continue speaking:

"Yesterday afternoon in the palace, my uncle explained that place to everyone. The secret passage was originally built by a certain emperor of the previous dynasty. It is said that the emperor at that time often left the palace in disguise and took that passage.

When my dynasty came, my uncle's mansion was there, and it was discovered during construction. I reported it to my father, who ordered that the exit at the end of the secret passage in the palace be filled up, and still pretend that they didn't know about it. My uncle also deliberately built his study there to keep this secret."

"That's really interesting, but how did the Second Prince know that?"

"That's unknown. After all, my second brother is dead, and no one can make a dead person speak." When this matter was mentioned yesterday, even my father didn't know the answer. It seems that this will become a mystery.

"In other words, the second prince originally planned to take that secret passage, then use gunpowder to blow open the seal, break into the palace, and finally kill the emperor and his men and take the throne himself."

Lu Anyuan nodded, that was true. "I didn't hear any explosion when I rushed to the palace yesterday. I think it was because the Cheng Palace was so large and the explosion happened underground, so we only saw black smoke but didn't hear any sound. When I saw the smoke, my second brother must have been knocked unconscious in the tunnel."

"Then why did it explode?" Since the affected area was within Prince Cheng's Mansion and not within the palace walls, it meant that the explosives exploded before the Second Prince reached the sealing position. This didn't make sense.

Lu Anyuan gave a thumbs up and once again admired Yi Xing’s sharpness. He was able to think of the key to the problem, which was really amazing.

"According to the investigation results given by the Ministry of Works and the Ministry of Justice, the gunpowder used by my second brother was extremely special and very flammable. It is possible that he found a talented person to modify the formula.

Improved gunpowder is much more powerful than ordinary black powder, but its disadvantage is that it is very easy to ignite and explode, so it needs to be carefully stored. I think when he led people to the tunnel in a hurry yesterday, there must be a problem with the storage, which caused him to explode. "
