Shocked! After planting, a sickly and charming first assistant will grow up.

Luo Nannan glanced at Yin Yao, and her eyes instantly turned red. She seemed to be trying her best to hold back tears. I saw her pity for her, which was endearing.

After making a set of expressions, it's a pity that it's a wink to a blind man.

No normal person in the hospital was indifferent to her appearance. In the end, she ran away crying, leaving behind a strong and stubborn figure.

Yinyao said thoughtfully: "You don't like her."

"I said it was so obvious, why do you still need to ask?" Luo Xi rolled her eyes.

After sending Nan Zhi to clean up the guest room, she returned to her main courtyard. There were some things she wanted to sort out.

"..."

The next day, it rained continuously——

Luo Xi leaned against the courtyard gate, lying in the rocking chair and drawing with a map.

"Is there anything you want in any of these places?"

Suddenly, a long, slender but scarred hand stretched out from the thorn, and touched the spot marked by Luo Xi.

The sudden appearance of people and sounds startled her. She bounced up from the rocking chair, patted her chest and took a step back: "Why do you walk silently?"

Yinyao stood there, narrowing his eyes, watching the little guy's series of actions, and after a while, he raised his lips and said, "It's over."

"You should put away the map immediately instead of jumping away like this."

Luo Xi: "???" We have met our match!

"I don't understand what you are saying." It is impossible to admit it, even in this life.

Yin Yao slowly straightened out her expensive robe, and spoke in a slow tone:

"The back of the recliner is facing the door. Didn't you deliberately seduce me? Are you acting as a door god?"

He turned around and sat in the rocking chair where Luo Xi had been sitting, and hooked his fingers: "I don't like to beat around the bush, just tell me what your purpose is."

Luo Xi stopped pretending and spread out the map: "Your Majesty, there is a kind of fuel that grows at high temperatures in the mountains. Are you interested?"

Yes! If she wants to mine coal, she must either cooperate with the court or rebel.

In order to dig some coal for rebellion, Luo Xi felt that it was a loss. Since this giant Buddha took the initiative to send it to her door...it was not in vain.

Hearing the 'high temperature fuel' Yin Yao became serious, sat up straight and asked: "How high is the temperature?"

"It's twice that of charcoal or even higher." Luo Xi didn't understand the degree, so she gave a general answer.

Hearing this, Yinyao's eyes widened and his mind became excited.

Dayong's iron-making technology is backward. If charcoal is replaced by coal and calcined at high temperature, can more impurities be removed from the iron?

He told Luo Xi his idea.

The latter pondered for a while, "Charcoal has larger pores and can burn fully, making the material column have good air permeability."

"Coal has small porosity and poor air permeability. It is easily broken when heated in the furnace, which causes the material layer in the furnace to condense and block, thus affecting normal smelting."

"It is feasible to use coal as fuel to make iron, but the equipment...that is, the furnace needs to be improved."

"Or turning coal into coke through coking. If you are interested, you can try both."

"You really understand!" Yin Yao let out a long breath, his eyes glowed with golden light. Although he didn't fully understand Luo Xi's words, he could understand roughly.

The two discussed this for more than an hour, and finally Yin Yao sincerely extended an invitation to Luo Xi:

"Could you help Dayong improve the existing iron-making technology?"

Then he added meaningfully: "Don't worry! Your Majesty is a wise king and will never treat you badly."

"Give me another two hundred and fifty?" Luo Xi blurted out. She remembered the two hundred and fifty gold for the threshing machine!

But this is also an opportunity for the court to take seriously.

She was not afraid of the court killing donkeys or imprisoning them for her own use. She just thought the chair was uncomfortable, so she tried changing it to a dragon chair.

Moreover, she also has a deeper meaning in doing so.

After thinking about the pros and cons, Luo Xi readily agreed: "I can improve the technology, but not now. The martial arts competition is coming soon, and I don't have time now."

"Also! Don't let the news out yet. We'll tell you later."

"..."

After Yin Yao left with satisfaction, Lu Yunjin Shiran walked down from the second floor and looked directly into Luo Xi's eyes: "What are you testing?"

Luo Xi laughed, "I have a rebellious heart, and I suffer from the fact that my teacher has no reputation. I won't see if the court will give my child a chance."

Licking his dry lips, this guy is so sharp!

Nothing escapes his eyes.

Seeing that she didn't want to talk, Lu Yunjin didn't press her, but said: "In Dayong, you don't have to trust the emperor, and your back can always be handed over to King Mo."

Are the reviews so high?

I can’t help but wonder: “What’s the relationship between you two?”

"Both a teacher and a friend." Lu Yunjin was referring to his previous life. Luo Xi obviously understood and changed the subject and asked, "What is that in your hand?"

Lu Yunjin shook the letter in his hand and said, "You are talking about this...a letter written by the best in the capital."

"Show it to me quickly." Luo Xi couldn't wait to see how much joy the top class could bring to her scumbag father and "prostitute" mother under her guidance.

After reading ten lines of the letter at a glance, Luo Xi clicked her tongue, "You are a very smart grandma. You should learn and apply it."

Lu Yunjin thought, if you are not smart, you will not be able to give birth to a son who will sit on the throne.

Luo Xi tapped her fingers on the table, and her voice came out through the back of the paper, "The letter said that the scumbag pair had been teased for a while, and the vicious stepmother began to fight back."

This letter is both to show off and to ask for follow-up advice.

Luo Xi couldn't help but think of something funny, so she couldn't help but laugh so hard.

Seeing her "clucking, clucking" and almost laughing like a little hen, Lu Yunjin raised his eyebrows, "What did you think of?"

"Do you know about 'crazy literature'?" she asked mysteriously.

Lu Yunjin shook his head.

Luo Xi took out a piece of letter paper and wrote four big characters "Crazy Literature" on the first row...

"..."

After dinner, Yin Yao and others bid farewell to Luo Xi, promising to send people to find the coal mine as soon as possible, and then agreed to meet again in the capital!

After people left and Lu Yunjin was sure to sleep, Luo Xi flipped her wrist, took out the bone hammer from the space, and carried it to Luo's house.

When she arrived, the Luo family had already gone to bed.

Luo Nannan went somewhere and was not at home.

Just in time, it was convenient for her to enter the old lady's east room without disturbing anyone.

In the darkness, looking at her old face covered with flesh, her light pupils turned into dark purple.

The old lady was awakened by the sound of tapping on the table. When she opened her eyes, she met a pair of gorgeous purple eyes.

Unconsciously, he fell into a trance.

The old man fell into a deeper sleep.

Luo Xi's movements suddenly stopped, and the first thing she asked was: "Is Luo Xi your grandson?"

The old lady's eyes became more and more confused, and the corners of her drooping mouth moved: "Of course."

"Then why did you treat her so harshly?"

"Why? Of course I don't like it."

Luo Xi took a deep breath, don't you like it? Very good, very strong reason. It seems that this old woman doesn't know anything.

In the dark night, I gazed vaguely at the West Room of my cheap parents...

"..."

Capital——

At this time, Mrs. Lu was caught in the rain and was blocked in the alleyway by a group of debt collectors. Her newly purchased maid was shivering behind her.

"Old woman! No matter whether your eldest son is Ping Xihou or Ping Beihou, it's written in black and white here. Your son owes the gambling house one thousand eight hundred taels."

"You have to pay back this money now, or not! Otherwise, the brothers will follow the rules and break his legs!"
