Jing Ting was very surprised when he learned this clue. According to Jiang Chengyi, the closed dungeon was filled with dust mixed with charcoal and sulfur. Once it encountered an open fire, it would inevitably be detonated. When it exploded, it happened to be heavy snow in the city, and dry snow would inevitably accumulate on the oblique window of the dungeon, which would block the sunlight outside. The view of the dungeon became worse, and the guards would definitely light the candle. Therefore, the open fire encountered dust and caused an explosion. This was the most reasonable inference. But now the dungeon guard who survived said that they sent people to clean the thick snow piled on the oblique window in time, which indirectly confirmed that their inference was not valid.

Jiang Chengyi was also suspicious because of this sudden turning point. If the explosion was not caused by the custodian in prison igniting the candlestick, then what was the cause of this disaster?

At present, the guard they interrogated overnight was because he changed his guards with other guards and hurried out to the cottage to go to the toilet. Therefore, what happened in the dungeon next was something he didn't know about.

Jiang Chengyi was eager to find some evidence from it, proving that Qin Ye might have been exploited by others in this case, which caused such a disaster. These days, he has been in a state of guilt and self-blame and has been unable to extricate himself.

The desperate investigation of the case day and night made Mu Yun, who was by his side, feel deeply distressed.

She repeatedly advised Jiang Chengyi that since the truth is already there... why not continue to investigate it without any use.

But he had a vague intuition that the case was not just 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 layout of the crime. However, based on his repeated exploration and investigation at the explosion site, Jiang Chengyi could basically confirm how Qin Ye committed the crime. However, when he investigated all the medicinal materials that Qin Ye asked Uncle Fang Si for this month, he found that Qin Ye did not buy the medicinal materials needed to make the five-color dispersion. Five-color dispersion is a kind of medicinal powder that can temporarily lose the sense of smell and taste, which is a common poison in the world.

What puzzled him was these five dispersions.

Sulfur is a medicinal material with a strong and pungent smell. Even if it is ground into powder, it is difficult to cover up its odor. If such powder is sprinkled into the dungeon, how could the Deng Mansion guard who came to change the duty not notice such a strong smell?

According to the files recorded by Uncle Fang Si of the Shuige medicinal materials purchased into the capital, Qin Ye did not buy any medicinal materials that could make five-color dispersions. When he was inquiring about the transactions of five-color dispersions in the world, he did not find that any gang of the rivers and lakes who purchased five-color dispersions had secret or open contacts with Zhou Yuanmo or Qin Ye.

He also thought that Qin Ye and Zhou Yuanmo had discussed the countermeasures, and through some means, he avoided his review and silently introduced the five-seed dispersion into the capital. But when he sent Xue Qing to catch up with the caravan escorting Qin Ye overnight to ask about Qin Ye's matter, Qin Ye was just silent.

Just when Jiang Chengyi thought that the five-color dispersion, as he inferred, was when Qin Ye introduced the capital from Zhou Yuanmo through a special way, he received an urgent report from the wind. His letter said: Just ten days before Qin Ye and his people were covered with sulfur powder and charcoal powder in the private prison, the young master Hengye, who had been following Fu Zhongwen, bought a large amount of five-color dispersion in the Dark Medicine Pavilion.

This made Jiang Chengyi have questions again.

While he ordered people to carefully investigate all the traces of Hengye's son since he pretended that Shi An was sent to Deng Yuan's mansion in the past two months, Jiang Chengyi began to look for passers-by who had passed through four alleys next to Deng Yuan's mansion before the incident.

If he inferred, after a month of investigation in Deng's mansion and determining the rest interval between the dungeon guards, Qin Ye took the masters summoned from the rivers and lakes to sneak into Deng Yuan's mansion's house and sprinkled charcoal, sulfur and other dust into the private prison to make arrangements - it should be early morning and when it was already bright. It would take some time for the dungeon's inclined window to make the sun shine into it after the sunrises.

Therefore, Jiang Chengyi believed that at that time, although most of the surrounding households brought sacrifices to the suburbs to worship gods, if someone sneaked into the tightly controlled Deng Mansion, there would still be passers-by passing by the alleys around Deng Mansion to notice. So he took Xue Qing to guard the bombed street on the left side of Deng Mansion, looking for witnesses who passed by the street and accidentally saw this scene, hoping to find some different clues.

Three days after he and Xue Qing were visiting each other and inquiring, Jiang Chengyi finally found an old man who had passed by the alley near Deng Yuan’s mansion at that time.

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

"At that time, I was walking past Xixiang and heading towards my home in East Lane, and I saw an adult man wearing a hat and a hat wandering around Deng's mansion in West Lane. I didn't pay much attention to this person. After returning home, I suddenly heard a sharp and sharp sound. So I hurried out from the house to look.

The sneaky adult man jumped to the high wall around the alley, holding a crossbow arrow, shooting arrows in the direction of the Deng Mansion. The arrow tied to the crossbow arrow he was holding was lit! The arrow with a fire. The man shot four times in a row. When he jumped off the wall and ran away, the Deng Mansion in the West Alley exploded. The sound scared me so much that I hurried back home. Fortunately, my family lives in East Alley, which is still a long way from Deng Mansion, and now it can be intact...."

This testimony made Jiang Chengyi more certain, and there were other people involved behind the explosion.

Qin Yeben didn't need such trouble, let a man stand on the wall of the alley and shoot rockets at the private prison of Deng's mansion like a swagger. He just had to wait patiently until night, and the prison guards lit the candlestick and detonate.

When he and Xue Qing returned to the mansion, Uncle Fang and Yan Ji happened to send news. It was said that when they sent fake Shi An to Deng Yuan’s mansion, Mr. Hengye was witnessed appearing in the alleys around Deng’s mansion, and seemed to be investigating something. Later, several brothers who were monitoring the Deng’s mansion said that Mr. Hengye had only appeared once, and the others who appeared again were strange faces that had never appeared in the alley. Only a few people were wearing the white tiger jade of the Shuangsha Gang, the gang where Hengye was located.

Jiang Chengyi was shocked to realize that this matter might not be Qin Ye’s fault.

Young Master Hengye is a major suspect in it.

Perhaps Qin Ye had never thought about using five-color dispersion to make the guards of Deng's private prison lose their sense of smell and taste, making them unable to detect the scent of sulfur.

He also wanted to make people notice that a large amount of sulfur and charcoal powder were sprinkled in the dungeon, so that these guards were alert, and promptly transferred Fei Shi'an from the prison and cleaned the powder with clean water.

However, the young master Hengye was ordered by Fu, and he must take Shi An's order. After realizing Qin Ye's plan, he used the plan and used the five-color dispersion to make the guards guarded in the private prison of Deng's mansion lose their sense of smell and taste. He then committed the crime in a high-profile manner, igniting the fire arrows and shooting through the diagonal windows of the dungeon. The diagonal windows were made of bright paper and were easily pierced.

This is the real cause of the Deng Mansion explosion.

Jiang Chengyi's guess hit the truth.

Qin Ye didn't want the dungeon to be detonated from the bottom of his heart. After all, the guards guarding the dungeon were innocent people. He had never put five-color dispersion on these guards, but hoped that they would find that the dungeon was covered with a large amount of sulfur powder.

But what he did not expect was that not only did the escorts of Deng's mansion not discover this, but the time when the dungeon was expected to explode was nearly half a day ahead of schedule.

Jiang Chengyi searched for witnesses at that time along the East Lane. One testimony after another of the civilians in the East Lane made him more sure of his thoughts. Just as he breathed a sigh of relief, he was glad that the culprit of the explosion was not Qin Ye, but news came from the East Mansion Department. It was said that the culprit of the explosion surrendered himself.

Jiang Chengyi and Xue Qing hurried back to Dongfusi.

But he saw Wang He, the master of Deng Yuan’s mansion, leaned over and knelt in front of the interrogation hall of the East Mansion Department and refused to get up.

After hearing the news, the Wei Wei Wei Chang Yu, the commander of the City Defense Army, Jing Ting, the Zhongdu official Cao Shangshu Zhao Qi, and the Ting Wei Dou Yuelan gathered together in the Eastern Prefecture Office.

Jiang Chengyi entered the main hall and sat in the upper seat, asking Wang He about his intention to come to the Dongfu Office this time.

"Who is in the hall?"

Wang He answered truthfully: "The villain is the guru of the Left Chief of the Shangshu Deng Yuanfu, and his name is Wang He."

Jiang Chengyi narrowed his eyes and frowned and continued to ask, "Do you come to Dongfu today to surrender?"

Wang He buried his head under his arm and replied, "That's right."

Jiang Chengyi then continued: "Raise your head."

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

Wang Hesheng's appearance was honest and honest, and his eyebrows and expression were more of a cowardly aura.

It was obvious that it had nothing to do with the Deng Mansion explosion.

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

So he continued to ask, "Can 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 Eastern Prefecture Department."

Jiang Chengyi threatened: "Since you know, the servants in the hall should also know what the consequences will be if you make a false testimony?"

Wang He said: "The villain knows."

Jiang Chengyi then opened the file file that the little official had prepared for him about Deng Yuan’s case and Wang He’s confession, and read it briefly.

He then asked, "Can the confession of the subordinate of the hall be true? Is the case of the Deng family bombing done by you?"

Wang He seemed to be forced, with a bleak expression, and a cold sweat on his head, and said tremblingly: "Sir, it's what the villain did."
