Time Travel: Conditional Wealth

Lu family.

The living room was crowded with people, all of them were soldiers ready for battle. They stood behind Father Lu as one camp, and the Lu family headed by Grandpa Lu as another camp. He Xi was well protected by Grandpa Lu.

Facing Grandpa Lu's powerful aura, Father Lu was obviously defeated, and his tone revealed helplessness: "Dad, this is a business matter, not a private matter."

Grandpa Lu raised his eyebrows and looked at him: "Business? What does a little girl like her have to do with your career?"

Facing his father, Father Lu, he could not be tough. There was no other way. If he could not talk, he would demonstrate it again: "Father, please look."

A soldier took out a box of self-heating hot pot, went to the kitchen to get water as if he was familiar with the place, and then began a long fifteen-minute wait.

Grandpa Lu watched the steam slowly coming out of the small box and couldn't help but become curious. Without using fire or electricity, it really started to emit steam.

The curling smoke from the cooking stove stirred the hearts of those present. They could not imagine what kind of progress this technology would bring if it was applied to the military. If soldiers could eat a hot meal without making a fuss on the battlefield, the battle would be half won.

Fifteen minutes later, the self-heating hot pot was cooked. The spicy and tender beef and the fresh aroma stimulated the taste buds. The aroma spread to every corner of the living room. Returning from the taste buds to reality, I thought about what the principle behind it was.

The instructions for the products sold by He Xi were very simple, without specifying the specific ingredients of the heating packs, only the main ingredients. What they wanted to know was He Xi's core technology, including a demonstration of the entire process of ingredient selection, production, and processing.

He Xi was still secretly thankful that she had not yet produced any results from the solar energy device.

He Xi opened a heating pack for a small hot pot and began to explain the main ingredients one by one, including sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt and quicklime.

These ingredients are combined to trigger a chemical reaction through the addition of water, releasing heat and steam that heats the food.

Specifically, quicklime (calcium oxide) reacts with water to release a large amount of heat and is a key ingredient in heat packs, which can quickly raise the temperature and generate steam for cooking food.

In addition, other materials in the heating pack, such as iron powder and aluminum powder, are able to generate heat through redox reactions, salt is used to adjust the reaction rate and temperature, and activated carbon is used to absorb and store gas to adjust the reaction rate and prolong the heating time.

The combined effect of the above ingredients enables the heating pack of the hot pot to be quickly heated to a higher temperature after adding cold water, meeting the needs of heating food.

He Xi stressed that adding water to the heating pack must be done strictly according to the instructions, using cold water and not hot water. Heating water may cause the water to boil violently and cause danger.

He Xi looked at the ingredients of the heat pack with them. She didn't think it was difficult, but she still felt strange that they were carefully examining the raw materials. She said, "I don't have anything to say anymore. Can we leave now?"

Father Lu briefly introduced the domestic situation at that time. There was a lot of work to be done, the country was poor and weak, the military was weak, and development was difficult everywhere. However, we did not retreat because of this, but kept forging ahead courageously.

He Xi was stunned. She knew this knowledge roughly and was not unfamiliar with it. After all, she was a liberal arts student majoring in accounting, and history was a compulsory course. To be honest, she still liked history more. Learning from history can help us understand the rise and fall of nations.

"Well, I understand. You should just say what you want to say." He Xi nodded silently, agreeing with him.

After a few seconds of silence, Father Lu said, "We hope that you can sell the technology to our department to increase military strength, enhance national defense confidence, and resolutely win the war. Of course, our department will pay for the formula, but the price will not be too high. You know that the country is not rich."

He Xi understood Father Lu's true purpose, and the tense expression on his face disappeared. His original proper standing posture disappeared, and his whole body showed a relaxed posture: "Why didn't you say it earlier? That's it? You are so serious, my calves are cramping from standing. If you don't want money, take it out and use it freely."

Lu Jinan helped He Xi sit on the sofa next to Lu's mother, lifted He Xi's calves and placed them on his legs to massage her to relieve her tense muscles, completely ignoring the fact that there were many military comrades present.

He Xi's face turned red with embarrassment and she said, "No, it will be fine in a while." She pushed Lu Jinan's hand away and tried to take her legs off his legs, but he didn't let go.

Lu Jinan chuckled lazily and comforted her: "Don't worry, my family's fine tradition is to spoil my daughter-in-law. As long as it doesn't involve state secrets, spoil her hard."

He Xi: "It's really okay."

Lu Jinan didn't let go.

After a few seconds of silence, Father Lu finally gave them a warm reminder: "I'm talking about national affairs now. You two should be serious. There are so many people here."

Father Lu: I am so lacking in authority, right?

Grandpa Lu: I’m still here, is there any room for you to show off?

Grandma Lu: Well, that’s good. He is a teachable boy.

Mother Lu: You are worthy of being my son. You know how to care for others.

Father Lu: Let’s talk about business!

Lu Family: I know. Didn't we give it to you for free? You can leave now.

Father Lu: ...

The guards at the back: We are not important, just pretend we don’t exist and continue.

Father Lu looked at the soldiers behind him: No, you didn’t have this attitude before you came. Oh, now I’m the bad guy?

Guard: I don't know what you are talking about.

Father Lu: ...

He Xi went to the room and tore off a piece of white paper. She wrote down the dosage and source of each ingredient in the heating packs for the self-heating hot pot she sold. She went downstairs and gave it to Father Lu, saying, "I don't have an exact dosage either. I just used my eyes and it's about right if I think it's about right."

Father Lu suggested: "It's better to be formal, so that everyone is safe."

He Xi nodded: "You don't understand, my eyes are the scale, I say how much is how much, it's just a matter of practice."

Father Lu was somewhat helpless and continued to ask: "Do you have anything else good?"

He Xi was stunned, and Lu Jinan sensed it. He looked up and said, "Are you here to buy goods from her?"

Father Lu was a little embarrassed: "What did I say, you bastard? You are protecting her like this, can't I ask your father?"

Grandpa Lu looked at Father Lu with a somewhat unhappy expression: "She is shameless and wants everything. If she knows everything, you should be laid off too."

Father Lu felt wronged: "You all bully me, how can I not save face?"

The guard behind him lowered his head and covered his ears with his hands when he heard the question.

Grandpa Lu kept staring at Father Lu with an oppressive look. Yes, the women of the Lu family should not be bullied. He was wrong.

Grandpa Lu: I’m forgiven.

Grandma Lu: This won’t happen again.

Mother Lu: You deserve it.

Lu Jinan: There is someone behind us.

He Xi timidly buried her face behind Lu Jinan. There were so many people around, it was so embarrassing.
