Just as the third prince sighed that life was so desolate, Mingruo was sitting leisurely on the back of the flames, looking at the infinitely beautiful sunset in the sky.

Si Haochen lowered his head and rubbed his chin against her cheek: "Are you worried about him?"

With the inexplicable family education yesterday, Mingruo's nerves are still relatively delicate today, and he immediately understood who Si Haochen was talking about.

"It's not 'worry', it's 'heartache'." Ming Ruo turned his little head and blinked at Si Haochen playfully.

"In my arms, I feel sorry for other men. It seems that my beloved concubine has not had enough family rules yesterday!" Although Si Haochen could see that this girl was trying to anger herself, she deserved to die. When she heard her say she felt sorry for others, she was so angry that she was so angry!

"My family is growing more and more, and they are actually able to tell whether the 'pills' are male or female." Mingruo looked at Si Haochen with admiration.

"What pill?" Si Haochen frowned slightly.

"I just feel sorry for the Seven Micro Pill. It can be sold at least 20,000 or 30,000 taels of silver if you take it out." Mingruo's cheeks were bulging, "But he is your nephew, so it's not easy to care about his money, hum!"

"Haha." Si Haochen was amused by the little princess of the wealthy concubine, "Will you give him some other medicine?"

"The Qiwei Pill is the cheapest one." Ming Ruo rolled his eyes, "I will lose more if I give him the Blood Pill."

"I'll give you 30,000 taels of silver when I go back. Who made him my nephew?" Si Haochen said with a smile.

"That won't work. Your money is mine. You give me my money. This is wrong." Mingruo shook his head repeatedly.

"What do you think you should do?" Si Haochen had no choice but to use his greedy little princess, who was lustful.

"Let me think about it again." Mingruo's eyes rolled.

When she returned to the other courtyard, Mingruo wrote a letter to her old apprentice. Si Haochen didn't know what she wrote, but her big eyes blinked with a sly smile on her lips... This little expression must be making some bad ideas.

Ming Ruo sent Xunyi to the emperor's capital to deliver a letter. When he turned back, he saw Chuyi carrying two gray pots in his hand. Chuyi heard the footsteps behind him and turned to salute Mingruo: "Princess."

"What did you take?" Ming Ruo frowned slightly. Seeing what Chu Yi was in his hand, he felt a little uneasy.

"The people of Beichi should have entered the imperial capital a few days earlier. They have been swimming in Luocheng. Later, they bought a few boxes of these jars from a Persian caravan. Before entering the imperial capital, they buried these jars in several places in the outskirts of the city... By the way, they also buried some near the camp of Duke Jingguo..."

Chu Yi’s positioning for himself was very clear. They all followed the princess’ secret guard Chu San’s surname Chu, and the princess was their master, and there was nothing to say. “There were always guarding these places a few days ago. The envoy of Beichi took away most of the people before he entered the capital. Only then did his subordinates have the opportunity to dig out two and show the prince what it was.”

"Have you opened this jar?" Mingruo asked again.

"It was opened, and the things inside were a bit pungent. I took them to the drug doctor and said that there was only a small poison, which would not be a big climate. But my subordinates felt that they had put in such a lot of effort and must have made some plans." Chu Yi was very sure of his intuition.

After listening to the narrative of Chu 1, Ming Ruo had already guessed what was here, but he still wanted to verify it: "Show me the open jar."

Chu Yi handed a pottery jar to Ming Ruo: "Hold it, look, this thing is buried in the soil, it's so dirty."

Mingruo used the equipment to make a "perspective" of the jar, and confirmed that there was no special starting device installed, so he opened the plug and squeezed a small pinch of black powder from it with his hands. As she thought, it was black gunpowder.

Mingruo rubbed his forehead and asked Chuyi to put the things in the yard, asking him to report everything he said to Si Haochen first: "Tell the prince, just say I know what this is, and let him come out to find me."

This is a flammable and explosive product, and it is not safe to get it into the house.

"Yes, the princess." Chu Yi went to the study and reported everything to the master.

When Si Haochen came out, he saw his little princess squatting under the eaves of the porch, fiddling with a pile of black powder with branches.

"Ruoer, what is this? What is its function?" Si Haochen also squatted beside Mingruo, looking at the black powder, it really smelled a little pungent.

"This is black gunpowder. It only takes a little spark or high temperature to burn quickly and regularly, and at the same time generate a large amount of high-temperature and gas substances..." Ming Ruo told Si Haochen about the reaction principle and destructive power of black gunpowder.

Si Haochen was a little suspicious: "These black powders are really that powerful?"

"If you don't believe it, we can try it."

"good."

According to Mingruo's request, Si Haochen quickly took her to an empty valley. Mingruo asked Chuyi to bury the "ceramic jar" according to the depth they dug out before, and then poured tinder oil on it. Mingruo roughly calculated the safe distance based on the formula and weight of the can of black gunpowder.

After letting everyone retreat to safety, he said to the first day of junior high school: "Star the rocket."

With a whoosh, the rocket drew a stream of light in the night.

"Everything is lying down." Ming Ruo covered his ears and the cat was lowered.

Everyone heard Ming Ruo's words, but the loud noise and tremor caused by the explosion scared everyone silly - they had never seen something so powerful, and they only felt their ears and heads buzzing.

When the fifteenth saw the princess squatting there covering her ears, she cast a resentful look at the princess. The princess knew that this thing could deaf people's ears, but she also covered her ears without telling them. The princess was so bad...

The little man in Mingruo's mind put his hands on his hips with a proud look on his face, so that he would not let you experience the tremor from the depths of his soul, how could you know how scared? If this "land mine" was not in the early stage and there was no lead or striker installed inside, it would be dangerous for you to dismantle it at will, okay!

Even in the face of such a scene, Si Haochen was still very calm and just asked: "Ruoer, what can control this fire thunder? And, can you replicate this fire thunder?"

"It is difficult for black gunpowder to explode when it gets damp and enters water, so it is more afraid of water." Ming Ruo's chin raised slightly, "As for 'replica', I can adjust the black gunpowder with greater power."

The ratio of the black gunpowder in the jar is not very perfect. Even if it is perfect, it can still synthesize "nitroglycerin". The power of the explosion is much more cruel than that of the black gunpowder.

"Okay." Si Haochen expressed his satisfaction. He could create and restrain his skills. No matter how powerful this thing is, it would be nothing in his opinion. Only the unknown is the most terrifying thing.

"Let's go back." Mingruo yawned.
