But no matter what the truth is, Amir doesn't have the energy to deal with it right now.

He can only think about escaping here as quickly as possible, returning to his hidden underground hideout to recover from his injuries.

Unfortunately, fate has not been kind to him.

Amir stealthily glanced outside the cave.

The dim sky began to drizzle with snowflakes again.

Once again, he couldn't continue his journey that night.

...

...

Compared to the unrest at Eagle Ridge, Black Pine Ridge was tranquil.

Evening.

In the warm manor hall, Avril carefully peeled the baked potato and spread sauce on it before feeding it to Luo De.

"How's this candy sauce?"

Avril asked tentatively.

Luo De swallowed the potato and nodded slightly, "The taste is good, but it's too sweet for me."

"Then I'll have Leia use less sugar next time." Avril pursed her lips.

"No need, I don't eat much; as long as you like it, it's fine."

Luo De said with a smile, "I just take a couple of bites occasionally."

Avril didn't respond and looked down at the drawings on the table,

"Drawing new machinery again?"

Avril asked.

Luo De nodded,

"Rolling mill."

"Huh?" Avril heard a brand new term.

"You see these two rollers, once they start rotating, they can press the heated iron material directly into iron sheets."

Luo De explained, pointing at the drawing: "Also, you can adjust the thickness of the pressed iron sheets by adjusting the distance between these two rollers."

According to the procedures Hammer mentioned earlier, the only part Luo De could help optimize was pressing the iron material into armor plates.

No need for much skill, using machines to replace manpower, simple and crude.

"Then, still use windmills to generate energy, drive the gears and these rollers?"

Avril looked at the drawing and thought aloud, "Can water power work too?"

"Congratulations, you've learned to give quick responses."

Luo De laughed as he wrapped an arm around Avril's waist.

Luo De had already instilled the concepts of energy and machinery into Avril.

As a well-educated noble Witch, Avril easily understood.

Luo De cleverly avoided explaining kinetic energy and potential energy concepts from the previous life.

Instead, with Vivian summoning Shadow Energy, he explained how windmills obtained the wind's energy from the air, and waterwheels obtained the water's energy from flowing water.

Then explained several energy conversion concepts that corresponded to wizard knowledge.

"After heating the whole iron material, repeatedly press it with the rolling mill, thus replacing the traditional hammering process."

"The apprentices press the iron material into flat materials, then cut it into the shapes needed for plate armor, and finally, have the blacksmiths participate in hammering for detail work and final shaping."

Luo De continued to explain.

Avril's eyes lit up, "With this, apprentices can do most of the work for plate armor!"

Luo De nodded.

"Those new blacksmiths, who make farming tools, can learn plate armor shaping directly."

Moreover, Luo De estimated that such a production method could reduce time by at least 50%.

After all, while blacksmiths rest during hammering, the rolling mill doesn't need a break.

Apprentices work in shifts, and flat materials can be continuously produced.

"Darling, you are truly brilliant!"

Avril gave Luo De a light kiss on the forehead, then curiously tapped his head,

"Where did you get all these magical pieces of knowledge from?"

"It's creativity."

Luo De shamelessly bragged.

No way, Luo De couldn't just say he had lived another life.

That would be more terrifying.

Avril nodded in agreement, "No wonder Prophet Bai Shuang says you are the Master of the Holy Land."

"Okay, let's continue working."

Luo De released Avril, "Quickly learn your Sea Race language."

Luo De didn't want to rush Avril, but there was a treasure trove of knowledge hidden underground, and Luo De was itching with anticipation.

"I have pretty much learned it," Avril said.

"Hmm?"

Luo De was a bit surprised, "So fast?"

"Of course, I can't let you down, can I?"

Avril said with a slight blush, placing her notebook in front of Luo De,

"Although I haven't memorized everything, I basically have an impression of it. If you don't believe me, you can test me."

"There's no need, I trust you."

Luo De wrapped his arms around Avril again, "Then we'll set off for the ruins tomorrow to first translate all the literature titles."

"No problem." Avril nodded.

"By the way."

After giving instructions, Luo De suddenly remembered something and asked, "Has Vivian set off?"

"She's already on her way back," Avril said, "She wanted me to ask you, do we really not need to kill the new heir of the Hawk Clan as well?"

"No need, it would draw too much attention."

Luo De shook his head, "And it's not of much benefit to us, just making a wedding dress for someone else, unnecessary."

When Eagle Ridge is calm is when Luo De needs to make a move; let Eagle Ridge remain in chaos.

Besides, this world is complex; Vivian is not invincible. If anything unexpected happens, it wouldn't be worth the risk.

Having Vivian come back to stay by his side was best.

"Okay, understood."

Avril nodded.

"Then go pack your bags, bring plenty of snacks, no one over at the ruins to make them for you."

Luo De stood up, "I'll go hand over the blueprints to Waller, let him start the production."

"Still working when it's dark?" Avril asked.

"Hand it over quickly so they can start work asap."

Even though the carpenters had already made windmills, the rolling mill was still a new machine to them.

To be cautious, Luo De still needed to explain everything comprehensively.

Avril nodded.

Just as Luo De reached the door, a guard hurriedly ran in.

"Lord, Wolfhoof sent someone to report that a White Wolf Magical Beast was found in Frost Wolf Forest!"

"Frost Wolf Forest?"

Luo De asked in confusion, "Is there such a place in Black Pine Ridge? How come I didn't know?"

The guard awkwardly explained, "It's where Wolfhoof and his group often hunt; seems like they named it themselves."

"Hmm?"

Luo De frowned, "Have Wolfhoof come to see me."
