A nation's industrial development begins with junior engineers.

When the broadcast came on, Jiang Xia was organizing engine blueprints.

Upon hearing that he had been transferred to the research and development department, he quickly realized what was going on. This must have been his mentor's doing.

Like Wang Kui, Li Changfu was also trying to pull Jiang Xia back to shore, fearing that he would unknowingly fall into the vortex of power.

Jiang Xia chuckled, picked up the blueprints, and headed to find Li Changfu.

"Aren't you afraid I'll lose my integrity? Then let's give you a shock and see whose heart is redder. A new broom sweeps clean, so let's make this furnace burn brightly!"

"Hey, where are you going?"

Ding Qiunan, carrying a large bowl, suddenly appeared out of nowhere, reeking of medicine.

Jiang Xia turned around and smiled at Ding Qiunan. Perhaps because the weight had been lifted from his heart, the smile was exceptionally sincere.

"I just finished drawing the blueprints, I'm going to go discuss them with my master!"

Dr. Ding was initially a bit angry. He had listened to Jiang Xia's pitiful story and painstakingly prepared the medicine for her, but before she could even drink it, she was about to run away.

But looking at Jiang Xia's smile, Ding Qiunan, who was always aloof, felt her face getting hot.

"No! You can only leave after you take your medicine! I've been waiting for so long!"

Upon hearing this, even Ding Qiunan herself was startled, her heart pounding.

How embarrassing! Did those words really come out of my own mouth?

Listening to advice is a fine quality of Jiangxia. Although he didn't want to drink it, he couldn't let others' good intentions go to waste.

Turning around to take the medicine, Jiang Xia frowned again as he stared at the dark liquid in the large bowl.

"Dr. Ding, can I not drink it?"

Ding Qiunan frowned slightly: "No, this is someone else's property~~"

"Uh-huh!"

Ding Qiunan cleared her throat: "No, this medicine was personally prescribed for you by Old Liu."

"Don't waste it, Old Liu hasn't made a move in a long time!"

"But you don't need such a big bowl, do you?" Jiang Xia compared the bowl to her head.

Wow, this must be at least 1.5 liters!

Ding Qiunan firmly shook her head.

Ding Qiunan nodded in satisfaction only after Jiang Xia forced himself to finish the bowl of medicine.

Finally, he took out a large White Rabbit candy and stuffed it into Jiang Xia's hand: "Good boy, there's a reward for drinking the medicine."

Jiang Xia patted his belly and heard a lot of water inside.

Luckily I didn't eat lunch, otherwise the medicine would have spilled out.

Watching Jiang Xia walk slowly and leisurely outwards with her feet turned outwards.

Ding Qiunan burst out laughing again, her palm burning as Jiang Xia's fingertips touched it.

The warmth traveled from her palms to her face, until her cheeks flushed crimson.

Head nurse Zhang Hongmei happened to walk in from the door and was quite surprised.

Even an ice queen blushes sometimes?

Then look at Jiangxia's back as he walks with a duck-like gait.

He frowned. Did this beautiful woman with a bit of a background have different tastes than ordinary people?

"Qiu Nan, who is that?"

"Ah, head nurse. That's a patient."

Zhang Hongmei smiled ambiguously, and Ding Qiunan's shy expression naturally revealed what she meant, as someone with experience in this field.

"Hey, which department are you from? Let me go ask for you?"

"However, she looks sickly and walks with an 'eight' gait, which is not attractive at all!"

Ding Qiunan hurriedly explained, "No, he's usually fine. He just took his medicine and is feeling a bit bloated!"

Zhang Hongmei wanted to joke, but when she heard that it was because he had taken medicine and was feeling bloated, she couldn't help but feel suspicious.

Her instinctive professional ethics led her to inquire.

"Who prescribed this medicine? This is the first time I've ever seen someone drink such a huge bowl of it."

Ding Qiunan wasn't bothered by Zhang Hongmei's question. After all, doctors and nurses were supposed to check each other's information.

She took out the prescription that Old Liu had given to Jiang Xia, "It was prescribed by Old Liu, so it shouldn't be wrong!"

"Old Liu? The professor from the medical university who came to inspect?"

"That shouldn't be the case!"

Zhang Hongmei muttered to herself as she carefully examined the document.

A moment later, Zhang Hongmei's strange gaze extended towards Ding Qiunan.

"What's wrong? Is there a problem?"

"It's not a big problem, but that young man had a tough time." Zhang Hongmei's expression was strange as she pointed to the bottom line of text on the prescription. "Look, what's this?"

When Ding Qiunan peeked out, she not only blushed, she was practically fuming.

"Boil three bowls of water down to one bowl, then it is ready to drink."

…………

By the time Jiang Xia arrived at his master's place with a belly full of medicine, it was almost time to leave work.

"Master... hiccup... Father"

Li Changfu looked up and saw his precious apprentice, heavily pregnant, walking briskly towards him.

"What mischief are you up to now, you little rascal?" Li Changfu reached out and pressed on his stomach; *gurgle*...

Jiangxia's throat immediately made a gurgling sound.

He quickly covered his mouth, took a step back, and dodged Li Changfu's rough hands.

He picked up the large bundle of blueprints wrapped in a bed sheet, gesturing for Li Changfu to focus his attention on it.

"Hey, what good stuff have you come up with this time?"

Jiangxia remained silent, afraid that the water would spray out.

He gestured to indicate that he needed to use the restroom. He told Li Changfu to look at it himself.

After a full three minutes of exhilarating spree, Jiang Xia was finally able to walk back to his office with normal steps.

Seeing that Li Changfu was busy looking at the blueprints, Jiang Xia did not disturb him.

He found some tea leaves, brewed them, and served a cup to Li Changfu first.

I huddled in a corner of the sofa, clutching my teacup, feeling dizzy, and needed to recover.

She gradually fell asleep again.

"Ring ring ring!!!"

The shrill doorbell rang, and Jiang Xia wiped her face as a black trench coat slowly slid off her body.

Jiang Xia quickly hugged it to his arms.

This garment is Li Changfu's prized possession; it's made of wool and is very valuable.

"You're awake? Tell me, what are you planning to do with this?"

Jiang Xia scratched the corner of his eye and moved closer to Li Changfu.

"Of course it's for drilling wells! With a drill bit, it'll hit the mark every time!"

Drill a well? Li Changfu's eye twitched. What a spendthrift!

"Hey, tell me, this is a crankshaft, right? Why would you do it this way?"

"Oh, you mean this part, I made a chamfer? I only made a slight change because our steel has low strength, and I didn't add any steps."

"Where is this?"

"The cylinder head, it forms the combustion chamber together with the cylinder." Jiang Xia cast a suspicious look at his master.

Li Changfu blushed and continued to ask, "Why is there a groove and a ring on this piston? What's the meaning of that?"

"Piston rings further seal the inside of the cylinder to prevent leakage. Hehehe~"

"What are you 'hey' for! I'll beat you up, you traitor who betrayed your master and ancestors."

Do you know how many improvement options there are for the Type 300? Do you know how to perform maintenance on the pre-furnace without shutting down the machine?

Tsk tsk, the old man was finally provoked by his apprentice's gaze and got angry. A series of questions left Jiang Xia with no choice but to lower his head and admit his mistake, saying that he was not good enough and needed to learn more from his master.

It's perfectly fine for a family to coax their own master!
