His innermost thoughts were revealed, and he ventured into a fictional dynasty with the system.

Qin Qianluo also looked toward the source of the noise, but because she was short, she couldn't see anything. She had to find a way to get out from among these tall and burly officials. Over there, Prime Minister Qin had already walked over and found that it was the Emperor and two princes in their everyday clothes, along with a group of officials, who were discussing something around the poultry farm.

Prime Minister Qin stepped forward, bowed, and asked, "Why is Your Majesty here? Has something happened?"

Upon hearing this, the Emperor turned his head and saw that it was Prime Minister Qin. He waved his hand, pointed to the biogas lamp, and asked, "What kind of lamp is this? It's so bright?"

Qin Xiang then noticed that there were many bright lights in the poultry shed. Because it was getting late, these lights were on, which made them so conspicuous. However, he didn't know that his youngest daughter had told him. He could only say helplessly, "I don't know either. My youngest daughter has never told me."

The Emperor waved his hand dismissively, telling him to go find Minister Qin. Minister Qin had no choice but to turn around and look for his daughter. Finally, he saw his youngest daughter, whom Minister Su had rescued from the officials of the Ministry of Revenue and the Ministry of Agriculture. Relieved, he watched the two of them walk over hand in hand and frowned. "When did Su Jinyun, that little fox, become so close to Luo'er?" Before he could ponder for long, Qin Qianluo walked up to him. He didn't have time to think further. He told his youngest daughter that the Emperor had also arrived and then brought Qin Qianluo before the Emperor. Qin Qianluo followed her father to the Emperor with a bewildered expression. After bowing, she said, "I was unaware of Your Majesty's arrival and failed to greet you. Please forgive me, Your Majesty."

The Emperor waved his hand dismissively, pointed to the biogas lamp, and asked again. Qin Qian stared blankly at the biogas lamp in the poultry shed, inwardly screaming in despair, "No, does Your Majesty and these officials really have to look at it in front of the poultry shed? There are biogas lamps not only here, but also in the main hall, or even in the buildings over there. Why are so many people crowding around the poultry shed asking questions? Don't they find it smelly? Although there's a biogas digester, so there's basically no smell, it's still scaring the poultry. I even saw the pigs and sheep hiding inside over there, ahhhhh..."

001 was also puzzled. "Perhaps it's because the Emperor and his ministers like it? Your Emperor is really... down-to-earth."

Upon hearing this, the Emperor froze. He had simply walked over there and only came to investigate out of curiosity when the lights suddenly appeared; he hadn't come specifically to look. This girl from the Qin family was slandering him! And what was a biogas digester? What was a biogas lamp?

We, the people being criticized, are also innocent. Who knew we would suddenly see the emperor in his everyday clothes, and then the lights would suddenly come on? Of course, we were curious and stayed to investigate.

Qin Qianluo calmed herself down and replied, "Your Majesty, this is a biogas lamp, a type of lamp powered by a biogas digester. Biogas digesters can be used for heating, lighting, cooking, and processing excrement, among other things. Your Majesty, please move to the main hall, where this type of lamp is also used."

Upon hearing this, the Emperor followed Qin Qianluo towards the main hall, with the others following behind. They exchanged glances, realizing the many uses of the biogas digester. They wondered if Lady Qin could provide a construction method, so that even without candles, they would have a means of lighting. It could also provide heating and cooking—truly a wonderful thing! Their thoughts raced, their steps unwavering, eager to find a way to build it.

Qin Qianlu led the Emperor towards the main hall, her mind racing as she spoke with 001: "001, do you think we should provide construction methods for these biogas digesters? I'm worried that if we promote them, some people won't know how to use them, potentially causing danger. These things can explode if not cleaned or used properly, and the pipes need regular cleaning. Although we can manufacture iron pipes now, can the Ministry of Works handle the workload?"

001 thought for a moment and replied, "If Luo Bao is willing to teach, then teach them; if not, then don't. At worst, just emphasize safety issues. Anyway, there are plenty of officials now, they won't be too busy. Everything should be done according to Luo Bao's mood. Even if he's unwilling, the Emperor can't threaten Luo Bao. If he dares to threaten Luo Bao, this system will blow up his palace."

Qin Qianluo's lips twitched, secretly relieved that only she could hear 001's words. Little did she know that everyone else could hear their conversation. "I won't threaten them; His Majesty is always lenient. If I were to teach them, I'm only worried that the common people wouldn't know how to operate it, causing unnecessary harm."

Upon hearing 001's words, the Emperor trembled, thinking angrily, "How could I be so unreasonable? When have I ever threatened this girl? This system of yours is so unreasonable! Luckily, this girl is a good person, otherwise she would have been led astray by you sooner or later." Hearing Qin Qianluo's reply, he calmed down slightly, nodding in satisfaction. "See, even this girl knows I'm lenient. You, 001 system, should learn from this."

The rest of them thought, "Oh my god, this is terrifying! This 001 is actually going to bomb the palace! We mustn't mess with Lord Qin in the future!" They shuddered and continued to follow.

When Prime Minister Qin heard that 001 was going to blow up the palace, he almost had a heart attack. Luckily, his daughter was kind-hearted, otherwise the whole family would have been ruined by 001.

Upon arriving at the main hall, he had the emperor sit at the head of the table. He decided in his heart that he should teach the people, so that the common people could have an easier time, and it would also save a lot of timber. Furthermore, it would provide a way to dispose of household waste.

After carefully considering his words, he said, "Your Majesty, this biogas digester has both advantages and disadvantages. The advantage is that the biogas produced by the digester can be used for lighting, cooking, and heating, and it can also effectively process the garbage, animal excrement, and straw generated in daily life. Furthermore, it can produce biogas residue and biogas slurry as agricultural fertilizer, which can also improve the yield and quality of crops and save a lot of materials."

The Emperor's eyes lit up as he listened, and the court officials also became excited. The officials from the Ministry of Agriculture were also delighted to hear that it could increase crop yields, and the officials from the Ministry of Revenue were already grinning when they heard that it could save money. Finally, the Emperor tapped the armrest of his chair with his finger, suppressing his excitement, and asked, "What about the downsides?"

Qin Qian paused, glanced at her father, Qin Xiang nodded to her, indicating that she should speak with peace of mind, and then said with a sigh, "The downside is that biogas is flammable, so it cannot be exposed to open flames. Also, if the construction is not well sealed or it is used improperly, it is easy to leak and cause poisoning, and in severe cases, it can explode. It also requires regular cleaning and maintenance, which requires experienced people to do. Your Majesty needs to train people who can do maintenance and cleaning."

The hall fell silent as everyone pondered the situation. There was danger, but the benefits outweighed the risks. After some thought, the Emperor asked, "What materials are needed to build a biogas digester?"

Qin Qianlu thought for a moment and replied, "Both cement concrete and red clay are fine. Red clay is adobe clay, and it works better. That's what we use on this farm."

The Emperor nodded upon hearing this, and was about to instruct the Ministry of Works to learn from Qin Qianluo when he heard 001's soft, childlike voice.

"Luo Bao, we mainly use black membrane biogas digesters; only the houses use red clay ones."

Upon hearing this, Qin Qianluo thought helplessly, "001, this technology doesn't exist in this era. Black membrane biogas digesters require geomembranes and PVC pipes, and we haven't even fully understood steel yet. It's too early to bring these out; it's better to use what we already have. And I already have to figure out how I know this. If we add a black membrane biogas digester, I'll be treated like a monster, captured, and burned."

Upon hearing this, 001 realized what was happening and disagreed with the last sentence, saying, "Anyone who dares to burn the treasure, this system will blow them up!"

Qin Qianlu had no choice but to comfort 001. 001 was good in every way, except that no one could treat her badly, not even in a metaphorical way. Thinking of this, a warm feeling welled up in her heart. It always unconditionally favored her.

After hearing this, everyone realized that it was indeed true. However, when they heard that childish voice say that someone was going to be blown up, they still twitched their lips. Don't worry, no one would dare to burn Little Master Qin. They are too busy taking care of him.

The Emperor's lips twitched, and he felt inexplicably at ease. It wasn't just about blowing me up; those things about membranes and tubes were indeed too profound and unsuitable for his dynasty. He decided to take it one step at a time. After thinking for a moment, he decided to ask about the source, otherwise the Qin family girl would become suspicious. So he asked, "How did you, Little Qin, know these things?"

Upon hearing this, Qin Qianluo paused in comforting 001, thinking that she had indeed asked. She closed her eyes briefly and replied, "Your Majesty, I enjoy reading books in my daily life. I happened to read something in a strange book and wrote it down, but that strange book can no longer be found."

After saying that, he thought to himself, "I can't find the strange book. Don't ask me where it is. I can't make this up anymore. This is too much for me."

The Emperor's lips twitched again, and he nodded, saying, "Records such a wondrous thing; it truly is a remarkable book. It's a real pity it's lost. Then, I'll trouble Minister Qin to teach the Ministry of Works the construction methods. I will order people to widely use it and also to carefully guard it. Can this method be applied to all regions?"

Qin Qianlu thought for a moment and replied, "It is suitable for the southern region. The winters in the north are too cold, so it is more suitable for things like heated brick beds, heated walls, and underfloor heating. The temperature in the south is more suitable."

The Emperor nodded upon hearing this, having already made a plan in mind: "Very well, then we will use biogas digesters in the south and heated brick beds, heated walls, and underfloor heating in the north. The people of the Ministry of Works should learn from Minister Qin as soon as possible."

The Minister of Works and Qin Qianlu bowed and said, "Your subject obeys the decree."

After the Emperor made the arrangements, dinner was also prepared. After asking the Emperor, Qin Qianluo had the servants serve the food. Halfway through the meal, an official asked in surprise, "What seasoning is used? There is no bitterness at all."

Upon hearing this, Qin Qianluo paused, her chopsticks still in her hand. She belatedly realized that privately manufacturing salt was now illegal, and hesitated, unsure how to respond. Seeing Qin Qianluo's wavering gaze, the official realized he had made a mistake and looked anxiously at Prime Minister Qin. Prime Minister Qin glared at the man, then looked at the Emperor. The Emperor nodded slightly, and Prime Minister Qin breathed a sigh of relief. Seeing the Emperor nod, Su Jinyun picked up a piece of food and placed it in the official's bowl, saying leisurely, "It's probably a chef's family secret recipe, which even Lord Qin may not know. If you find it delicious, then eat it quickly."

The official nodded hurriedly, lowered his head to eat, and dared not speak. Qin Qianluo saw that Su Jinyun had helped her out of the predicament and smiled at her. Out of the corner of her eye, she saw that the emperor did not suspect anything and breathed a sigh of relief.

While shoveling food into his mouth, he chatted with 001, "001, I think I forgot to give the salt recipe to my dad. We almost got caught producing salt on our own."

001 didn't care; no one knew Luo Bao could refine salt anyway. "It's alright, Luo Bao. I'll give you the same thing tomorrow. Nobody knows you can do this, so don't worry."

Qin Qianlu sighed helplessly, "The law is above all else. I overlooked it. Luckily, no one noticed. I need to give my father the recipe for refined salt as soon as possible, and give him the sugar too. Otherwise, if I forget again and suddenly bring out the sugar, it'll cause trouble."

001 responded, "Okay, Luo Bao, I'll print it right now."
