When Jing Ting learned this clue, he felt very strange. According to Jiang Chengyi, the closed dungeon is full of dust mixed with charcoal and sulfur, which will inevitably be detonated if it encounters an open flame. At the time of the explosion, there was a heavy snow in the city, and the dry snow was bound to accumulate on the sloping windows of the dungeon, which would block out the sunlight outside, and the dungeon's vision would deteriorate, and the keepers would have lit candles. Then the open flame met the dust, causing an explosion. This would have been the most reasonable assumption. But now the dungeon guards who survived said that they had sent someone to clear the thick snow piled up on the sloping window in time, which indirectly confirmed their inference.

Jiang Chengyi was also suspicious because of this sudden turn. If the explosion was not caused by the ignition of the candlestick by the prison guards, then what was the cause of the disaster?

At present, the guard they interrogated overnight was fortunate to escape because he changed guards with other guards at that time and hurried out of the dungeon to the thatched hut to go to the toilet. Therefore, what happened next in the dungeon was unknown to him.

Jiang Chengyi was anxious to find some evidence from it, proving that Qin Ye may have been used by others in this case to cause such a catastrophe. These days, he has been trapped in guilt and self-blame, and it is difficult to extricate himself.

The desperate investigation of the case day and night made Mu Yun, who was with him, feel distressed.

She advised Jiang Chengyi many times, since the truth is already there... Why bother to continue the useless pursuit.

But he had a faint intuition that this case was by no means as simple as Qin Ye's layout.

Before Jiang Chengyi knocked Qin Ye unconscious and sent him out of the capital, he had never asked Qin Ye about the specific process of the murder arrangement. However, based on his repeated exploration and investigation at the explosion site, Jiang Chengyi can basically confirm how Qin Ye committed the crime. However, when he investigated all the medicinal herbs that Qin Ye had asked for from Fourth Uncle Fang since this month, he found that Qin Ye had not purchased the medicinal materials needed to make the five color dispersions. Wusesan, a kind of medicine powder that can make people temporarily lose their sense of smell and taste, is a kind of poison commonly used in the rivers and lakes.

And it was these five colors that made him wonder.

Sulfur is a medicinal herb with a strong pungent odor. Even if it is ground into powder, it is difficult to hide its smell. If such powder was sprinkled into the dungeon, how could the guards of the Deng Mansion who came to change the guard later not notice such a strong breath?

Judging from the dossier recorded by Fourth Uncle Fang of the transportation of medicinal materials from the Water Pavilion to the capital, Qin Ye had indeed not purchased any kind of medicinal materials that could make five color dispersions. And when he ordered Qianji to investigate the buying and selling transactions of the five colors in the rivers and lakes, he never found that any of the people who bought the five colors of the gangs had any secret or open contact with Zhou Yuanmo or Qin Ye.

He also thought that Qin Ye must have discussed countermeasures with Zhou Yuanmo, and through some means, he avoided his censorship and silently introduced the five colors into the capital. But when he sent Xue Qing to catch up with the caravan escorting Qin Ye overnight, he asked Qin Ye about it. Qin Ye was just silent.

Just when Jiang Chengyi thought that the five color scatters were just as he deduced, Qin Ye was introduced into the capital from Zhou Yuanmo through a special channel, but he got an urgent report from the wind. According to his letter: Just ten days before Qin Ye led people to fill his private prison with sulfur powder and charcoal powder, the people in the rivers and lakes who had been following Fu Zhongwen, Hengye Gongzi, had purchased a large number of five colors in the Dark Medicine Pavilion.

This made Jiang Chengyi question again.

While he ordered someone to carefully investigate all the traces of Hengye Gongzi in the past two months since he was sent to Deng Yuan's mansion under the fake Shi An, Jiang Chengyi began to look for passers-by who had been in the four alleys next to Deng Yuan's mansion before the incident.

According to his inference, after Qin Ye went through a month of investigation in the Deng Mansion and determined the change of guard and rest of the dungeon guards, he sneaked into Deng Yuan's mansion with the masters gathered from the rivers and lakes, and sprinkled charcoal, sulfur and other dust in the private prison for layout - it should be early in the morning, when the sky is already bright. The dungeon's sloping windows take some time after the sun rises for sunlight to shine in.

Therefore, Jiang Chengyi believes that at that time, although most of the surrounding households carried sacrifices to the suburbs to worship the gods. But if someone sneaks into the Deng Mansion, which is heavily fenced, there should still be passers-by passing by the alleys around the Deng Mansion to notice. So he took Xue Qing to guard the bombed-out street on the left side of Deng's mansion, looking for witnesses who passed by the street at that time and inadvertently saw this scene, hoping to find some different clues.

Three days after he and Xue Qing visited and inquired around, Jiang Chengyi finally found an old man who was passing by the alley near Deng Yuan's mansion at that time.

When he asked the old man if he had ever seen someone sneak into the Deng Mansion, the old man said something that surprised him.

"At that time, I was passing by West Lane and was walking towards my home in East Lane, when I saw an adult man wearing a hat and hat sneakily wandering around the Deng Mansion in West Lane. I didn't pay much attention to him, but when I got home, I suddenly heard a piercing and sharp sound of breaking bamboo. So he hurried out of the house to see.

I saw that the sneaky adult man actually jumped onto the high wall around the alley, holding a crossbow arrow, and was shooting an arrow in the direction of Deng Mansion. The arrow tied to the crossbow he was holding was lit! Arrows with fire. The man shot four times in a row. When he jumped off the wall and fled, the Deng Mansion in West Lane exploded with a bang. The sound frightened me and I hurried home. Fortunately, my family lives in Dongxiang, which is still a long way from the Deng Mansion, and now it is intact....."

This testimony made Jiang Chengyi even more certain that there were other people behind the explosion case.

Qin Ye didn't need to be so troublesome, so he let a man stand on the wall of the alley like a swagger and shoot rockets at the private prison of the Deng Mansion. All he had to do was wait patiently until night, when the prison guards lit the candlesticks and detonated them.

When he and Xue Qing returned to the house, it happened that Fourth Uncle Fang and Yan Ji sent news. is saying that when they sent the fake Shi An into Deng Yuan's mansion, Hengye Gongzi was seen appearing in the alleys around Deng's mansion, as if he was investigating something. Later, several brothers who monitored Deng's mansion said that Hengye Gongzi had only appeared once, and the others who appeared again were all unfamiliar faces that had never appeared in this alley. It's just that a few people are wearing the white tiger jade of the Jianghu gang where Hengye is located, the Shuangsha Gang.

Jiang Chengyi was shocked to realize that this matter may not be Qin Ye's fault alone.

Hengye Gongzi is seriously suspicious of it.

Perhaps Qin Ye didn't even think of using the five colors to make the guards in the Deng Mansion's private prison lose their sense of smell and taste, so that they could not detect the smell of sulfur.

He also wanted to make people aware of the large amount of sulfur and charcoal powder that had been sprinkled in the dungeon, so that the guards would be alert, and they would be able to remove the fake Shi An from the prison in time to clean it with clean water. I read books

However, the prince of Hengye was ordered by the Fu clan to take Shi An's order, and after perceiving Qin Ye's plan, he planned to make the guards in the private prison of the Deng Mansion lose their sense of smell and taste by using the five color dispersion, and then committed a high-profile crime, shooting through the inclined window of the dungeon with an arrow that ignited fire. The slanted windows are made of open paper and are easy to pierce.

This is the real cause of the explosion in Dengfu.

Jiang Chengyi's speculation is right in the truth.

Qin Ye, from the bottom of his heart, didn't want the dungeon to be detonated, after all, the guards guarding the dungeon were also innocent people. He hadn't given the guards a distraction, hoping that they would find the dungeon covered with a large amount of sulfur powder.

But what he didn't expect was that not only did the guards of the Deng Mansion not find out, but the time when the dungeon was expected to explode was advanced by nearly half a day.

Jiang Chengyi searched for the eyewitnesses at the time all the way along the East Lane, and the testimony of the civilians in the East Lane made him more and more sure of what he was thinking, just when he was relieved in his heart, glad that the culprit who finally caused the explosion was not Qin Ye, but the news came from the East Mansion Division. It is said that the culprit of the bombing case actually surrendered himself.

Jiang Chengyi and Xue Qing hurried back to the Dongfu Division together.

But when he saw Wang He, the master of Deng Yuanfu, he knelt down in front of the interrogation hall of the Dongfu Division.

Hearing the news, the guard captain Changyu, the commander of the city defense army, Jing Ting, the commander of the city defense army, Cao Shangshu, Zhao Qi, the central capital official, and Dou Yueqi, the court captain, gathered in the Dongfu Division.

Jiang Chengyi entered the main hall, sat down on the upper seat, and asked Wang He about his intention to come to the Dongfu Division this time.

"Who's in the hall?"

Wang He replied truthfully: "The villain is the master of Shangshu Zuocheng Deng Yuanfu, whose name is Wang He. ”

Jiang Chengyi squinted, frowned and continued to ask, "You came to the Dongfu Division today, did you surrender?" ”

Wang He buried his head under his arm and replied, "Exactly." ”

Jiang Chengyi continued: "Raise your head. ”

The middle-aged man in the coarse clothes in the hall stood up tremblingly and looked at Jiang Chengyi.

Wang Hesheng looked loyal and honest, and there was more cowardice in his eyebrows and expression.

At first glance, it has nothing to do with the Deng Mansion explosion case.

But since he surrendered himself, Jiang Chengyi could not interrogate him at will and drove him out of the Dongfu Division.

So he continued to ask: "Do the people in the hall know where this place is?" ”

Wang He nodded timidly and said, "The villain knows that this is the head of the East Mansion." ”

Jiang Chengyi threatened: "Since you know, the people in the hall should also know, what are the consequences if you testify falsely?" ”

Wang He said: "The villain knows. ”

Jiang Chengyi opened the file on Deng Yuan's case that the little official had prepared for him a long time ago, as well as Wang He's confession, and read it cursoryly.

Then he asked, "Can the confession of the courtiers be true?" The Deng Mansion explosion was all done by you? ”

Wang He looked bleak as if he was being persecuted, his head was full of cold sweat, and he trembled and said: "My lord, it was the villain's doing." ”

Jiang Chengyi said again: "The people in the hall will tell the process of committing the crime according to the number!" ”
