Dust will also explode, Gu Qing sighed, "You don't understand if you tell me. In fact, it's either a firearm explodes or a dust explosion."

"What should I do if I do something in the palace?" said the short man, "I'm afraid that it's not the people in the palace who are going to come and take care of him."

"Without conclusive evidence, he dare not take me! What should he do if he can't take me?" Gu Qing said calmly, "Don't worry, you should eat and drink after you go back, and Li Chengqian can't take me."

When the short man and the fat monk heard Gu Qing say this, they didn't say anything more and turned around and left.

The rubber under the sun has not solidified. It seems that it has failed again. What was wrong? Gu Qing was thinking about it, and Fan Jian walked and said, "Head of the family, the Supreme Emperor is here."

Gu Qing looked back and saw Li Er walking in swagger.

"What are you busy with?" Li Er walked and said.

"I'm making rubber." Gu Qing's eyes returned to the unsolidified rubber, and used wooden strips to pick up some observations. The smell was strange and the color was not right.

Li Er looked curious, "What's the rubber thing?"

"A thing that needs to be used in industry." Gu Qing explained and came back to his senses and said, "It seems that His Majesty already knows the matter in Chang'an."

"Do you know too?" Li Er asked back.

"If this matter really has nothing to do with me, do you believe it or not?"

Li Er nodded and sneered, "I am here this time to hear your explanation."

"It seems that my explanation of "white teeth" must be useless." Gu Qing said, carrying a large bag of wheat flour from the kitchen, "Actually, the mystery lies in this flour. What really exploded is not my firearm, which is the powder."

Li Er glanced at it and said, "This is food. Could it be that food can harm people?"

"Actually..." Gu Qing scratched his scalp and said, "In fact, this is not harmful. Food is innocent, but food can also be fried under a specific situation."

"What does it mean?" Li Er asked.

"Flame! Dust! Enclosed the narrow space." Gu Qing took Li Er out of the house and said, "In a dry environment, the wheat husks are not clean, especially many people do not eat so finely. When they cook, the wheat flour everywhere, and the fine dust will rise in the closed and dry space to form a dust environment, which will also explode when the amount is very high."

"Gu Qing, are you going to fool me like this? If you tell the truth, I will not care about it even if you say it has nothing to do with you." Li Er was a little angry, "If you make up such a ridiculous statement, can't everyone in Chang'an eat food, according to your words."

"It's not like this. It's really going to explode, but there are certain conditions." Gu Qing said, "Your Majesty, why don't we try it?"

Li Er stared at Gu Qing, "Okay! I want to see how you want to try?"

Gu Qing found a small house outside the village where no one lived, which was almost abandoned. Gu Qing pushed open the door and used the sunlight to see the dust particles floating in the house. Li Er stood outside the house and looked at Gu Qing curious about what he was going to do.

Open the wheat flour bag, Gu Qing first lit the fire here, and it was filled with wood. It took about a cup of tea to burn it completely. Taking advantage of this time, Gu Qing sprinkled the wheat flour in this small house, causing the whole house to form a dusty environment, quickly run out of the house and close the door.

"What the hell are you doing?" Li Er was puzzled.

Gu Qing closed the door and stepped back step by step and said, "Your Majesty will wait for a moment."

Li Ergu is suspicious.

"Your Majesty retreated a little bit." Gu Qing pulled Li Er back step by step.

After the two retreated, Gu Qing watched thick smoke begin to emerge from the cottage. It should be almost the same. Li Er looked at it for a while, and saw that the cigarette was getting less and less, "Gu Qing, what are you going to do."

"Your Majesty, don't go over!" Gu Qing grabbed Li Er.

Bang!

With a loud bang, the whole house suddenly exploded, and wood chips flew everywhere.

Fortunately, Li Er did not walk over, and Gu Qing let out a long sigh, fortunately the power was not so great.

The suspicious Li Er saw Gu Qing replica an explosion with his own eyes, but he still wondered whether Gu Qing was making a fool of himself, "Gu Qing, what did you do?"

"I didn't do anything. In fact, dust will explode. As long as there is a similar bad situation, it will explode. If your Majesty still doesn't believe it, just try it." Gu Qing said, "I can't explain it clearly for a while if I want to explain it. Anyway, that's it. This has a lot to do with oxygen, dust and some flammable substances."

"I understand." Li Er nodded thoughtfully.

"That's good." Gu Qing said with a smile.

"I have another question." Li Er said again, "If it explodes like this, will ordinary people have such dangers?"

"Actually, it's better to remember to open the window when cooking. Most people will open the window to cook, and there is very little dusty environment, unless it's a house that has not been cleaned for a long time and is covered with dust. Generally speaking, this will not happen to ordinary people."

"You still have to be careful." Li Er nodded solemnly.

When he returned to his home, Li Er listened to Li Junxian's report, "So Chengqian wants to take Gu Qing."

"Return to the Supreme Emperor." Li Junxian said, "In the court, many ministers criticized Gu Qing. Your Majesty did not say anything, but he still asked Di Renjie to tell the situation of this case. There is no evidence. If there is conclusive evidence, this is the best time for Your Majesty to win Gu Qing."

"I understand." Li Er nodded, "You go with me to do something!"

"Yes!" Li Junxian replied with a bow.

"Wang Qin!" Li Er ordered Wang Qin again, "Get a bag of powder."

Li Junxian and Wang Qin, Li Er conducted several experiments, and two successes were successful. It seems that it is not a pretentious thing, but there is really a saying that dust explosions are like this.

"Your Majesty, this is not how it happened." Li Junxian asked in confusion.

"It seems that Gu Qing did not lie to me." Li Er's face was solemn.

Will fans explode? Wang Qin was really scared. According to this, how many people live in danger? It would be wrong to take a closer look. If they really could blow up the people of the Central Plains, wouldn’t they die? He looked at Li Er in confusion.

Li Er nodded and said to Wang Qin, "If too many people know about this matter, it will inevitably cause panic. I will pass on my words to Chengqian. I will not investigate this case. Stop it all! Let it go."
