Although Leng Qiyue had given Mu Fei an idea, the opportunity had yet to arrive. It took a few days for Mu Fei to send a man to the cold palace.

"This subject, Yan Su, kowtows to Imperial Concubine Yue, Imperial Concubine Die."

Leng Qiyue sat on a chair and studied the man kneeling in front of her. Yan Su? Serious? However, from the looks of it, this man was just like his name. He had a huge stature, bronze skin, clear and deep facial features, and wore a crimson official uniform. He wore a saber at his waist. "However, although this man's appearance was not bad, his expression was stiff. It could be said that his face had no expression at all. It was completely wooden.

Leng Qiyue nodded. "Get up. This is the cold palace, and we're only concubines that have been demoted. So there's no need for you to call us the Empress."

"Thank you, esteemed Empress." Yan Su stood up, his left hand naturally supporting the handle of his saber, looking ready to go.

Leng Qiyue poured a cup of tea for Yan Su and smiled. "Come, have a cup of tea."

Yan Su remained expressionless as he said, "I would not dare."

Seeing that he wasn't drinking, Leng Qiyue pointed at the chair at the side and said, "Sit."

Yan Su was still expressionless as he continued to say the "Three Character Classic". "This subject dares not."

Leng Qiyue cursed in her heart, "Mu Fei, you don't have anyone else? Sent over this wood. "What else would he do other than say that this subject doesn't dare?"

Die Fei who was at the side couldn't help but anxiously ask, "What's wrong with you? You don't dare to drink tea, you don't dare to sit, what else do you dare to do? "Tell me, what exactly did you come here for?"

This time, Yan Su finally had an expression on his face, but in his eyes, an inexplicable emotion flashed across his face. It was taunting, but also scornful. "To reply esteemed Empress, esteemed Empress Mu has sent this subject to protect the safety of the two esteemed emperors."

Die Fei said mockingly, "You look quite sturdy. I wonder what abilities you have?" Her eyes inadvertently caught sight of a bird's nest on a large tree by the wall. She pointed at it and said, "Go and bring that bird's nest to me."

Yan Su raised his head and took a look. The bird's nest was two rows away from where he was standing now. He clasped his hands together and said, "Yes." Before he finished his sentence, he had already gotten up from the ground. With a somersault, he stood firmly on top of the branch of the tree and easily took down the bird's nest. Then, he somersaulted back to his original spot, not missing in the slightest.

Leng Qiyue cheered in her heart. This Yan Su's Qing Gong was not bad. Although her martial arts were sealed, her eyes were still bright. She could already tell that this Yan Su was not someone to be trifled with.

Die Fei looked at the nest Yan Su had given her and saw three unhairy young birds. She said in disgust, "How ugly, throw it away."

Yan Su's wooden face finally revealed a clear emotion — frowning. He did not throw away the nest, but glanced at the tree again.

Leng Qiyue found it interesting. Although this Yan Su did not look like he was smiling, he was actually a kind person. His expression and actions told Leng Qiyue that he wanted to put the bird's nest back where it was.

People who don't even want to hurt birds should be trusted.

"Yan Su, if you can jump out of thin air and put the bird nest back, I will believe that your kung fu is good." Leng Qiyue pretended to be contemptuous.

Yan Su let out a breath of relief. He rose from the ground and landed on a branch without turning over. He then carefully put the bird's nest away and even broke a few branches to reinforce the bird. It was obvious that although this man's appearance was stiff, his heart was soft and he was a bit depressed.

A strange idea suddenly popped into Leng Qiyue's mind. She really wanted to see this man go crazy. That must be very interesting.

Yan Su Fei landed back on the ground. He glanced at Leng Qi Yue with his tiger like eyes.

Leng Qiyue stood up and clapped her hands. "Okay, your Qing Gong is quite impressive. Next, let's begin our experiment."

Leng Qiyue walked to the back of the house, followed by Die Fei, and Yan Su kept a distance of one meter from the two of them.

In the empty space behind the house, there was a bamboo basket about one meter in diameter. The bamboo basket was connected to a huge leather bag with six ropes. Butterfly Consort and Yan Su were filled with pride when they saw the item.

Leng Qiyue walked up to the bamboo basket and fiddled with the rope. Then, she lit a fire with a fire piston and let the hot air fill the leather pouch. After the time it took for an incense stick to burn, the leather pouch actually began to float up. Fortunately, there was a rope tied to the bottom of the bamboo basket, otherwise, it would have been taken away.

Leng Qiyue smiled. "This is called the Wishing Lantern. The things in my hometown were originally very small. People would write their wishes on it and let it fly. That way, the lamp would carry your wish and fly into the sky for the gods to see."

This was a hot air balloon. However, Leng Qiyue would not explain too much because she felt that it was very difficult to understand the intelligence of these ancient people.

Die Fei touched the bamboo basket curiously like a little kid and tugged on the rope. She smiled and said, "No wonder you could pull me to make this leather bag all these days. So you can fly."

It was the first time that Yan Su had seen such a thing. Surprise flashed across his eyes, but his face remained expressionless.

"Leng Qiyue added some wood to the brazier, making it burn even more vigorously." "Yan Su, you go on up. I'll untie the rope and wish that the lamp will carry you up. Even if you fall on the way, you won't be harmed by it with your Qing Gong."

Yan Su nodded his head. He replied in a dull tone and then jumped in. Leng Qiyue untied the rope. For safety's sake, she prepared a long rope and tied the other end to a tree.

Taking advantage of the fire, the Wishing Lamp slowly rose, but when it was seven or eight meters away, it slowly descended. When the bamboo basket landed on the ground, Yan Su jumped out. His tiger-like eyes were actually shining with excitement.

Leng Qiyue sighed dejectedly. She couldn't understand how she fell down like this. She looked at the brazier and saw that most of the wood had already been burnt, leaving only red charcoal.

"Yan Su, can you find some coal?" Leng Qiyue knew that the firepower was insufficient, but wood fire could not be used to pour oil. This was because pouring oil could only shorten the fire's lifespan. If one wanted to maintain the fire for a long period of time, they would have to use coal.

Yan Su shook his head and asked, "Niangniang, what is coal?"

Leng Qiyue was stunned. Could it be that there was no coal here? She had a headache. After thinking for a moment, he said, "Coal is black, piece by piece. It's like stone, but can burn."

Yan Su bowed and asked, "Your Highness, are you talking about carbon?" With that, he pointed at the dying charcoal in the brazier.

Leng Qiyue was speechless. It seemed that this place really did not have any coal, or had yet to be developed.

When Die Fei saw Leng Qiyue's serious expression, she anxiously asked, "Little Sister, don't you think that without that thing, I won't be able to leave the cold palace?"

Leng Qiyue patted her shoulder and said, "It's fine. Three days from now, you will be fifteen. On that day, I will definitely let you leave the cold palace." However, this Wishing Lamp does not have enough firepower. Carrying one person would only raise it up to twenty feet. If we were to carry two people, I don't think we would be able to fly. "

Die Fei asked doubtfully, "Why do we need to carry two people?"

Leng Qiyue looked at Die Fei, "Sister, of course you went up together with Yan Su. If you went up by yourself, I'm sure I could fly even higher, but I'm afraid that if something happens to me, sister will be injured. If he's with Yan Su, his Qing Gong will bring his sister down safely. "

Die Fei lowered her head and thought for a moment. Then, she suddenly raised her head, and said with a resolute look in her eyes, "Little sister, I have no choice but to give it my all in order to leave the cold palace. "Let me go up myself. If something happens, I think Yan Su will catch me too." After she finished speaking, she cast her gaze towards Yan Su.

Yan Su clasped his hands together and said, "Your subject will definitely protect the Empress."

When Leng Qiyue saw that the butterfly concubine had made up her mind, she didn't need to hesitate anymore. She said to Yan Su, "Tell Mu Fei to prepare a new white leather for me. I want to make another one. Time is of the essence, I hope you can bring it tonight."

"Yes, this official will take his leave." Yan Su turned around and left the cold palace.

Leng Qiyue held onto the hand of the butterfly Concubine and asked, "Has elder sister made up her mind? If I fail, my sister might fall. "

Die Fei said with a determined smile, "Little sister, this is my only chance to leave the cold palace, I have to give it a try. My father is an elder of the three dynasties, and we, the Hua family, are loyal and loyal to the Eastern royal family. Prime Minister Zuo was an elder of the four dynasties and was already dissatisfied with the Imperial Family. Otherwise, why would he force the late Emperor to become the emperor? From what I see, the Zuo family is plotting to usurp power. "Therefore, I must leave the cold palace and suppress Zuo Furong's anger. With our Hua family's restraint, the Minister of the Left will not act rashly."

Leng Qiyue had some doubts about the matter regarding Dongfang Haotian's position as the emperor. Now that she heard the Butterfly Concubine say this, she definitely knew the inside story. It would be better to ask her about it today.
