The blacksmith's brother also had a warm smile on his face and quickly asked Zhiyin to sit down and talk slowly.
Without hesitation, Zhiyin immediately took out the blueprints for the return furnace.
The blacksmith was so shocked by the three pages of drawings that were filled with writing that he almost dropped his jaw and couldn't help but swallow hard.
Her voice was a little shaky, "Yinyin, what's this?"
"Hehe, you'll see when you take a look, it's a method for making a furnace."
"A stove? It's that big?"
The blacksmith was utterly shocked, admitting that he hadn't seen enough of the world.
But she quickly adjusted her mindset and accepted it.
The more he looked, the more alarmed he became, and his brows furrowed even more tightly.
His appearance made Zhiyin's heart pound with anxiety, fearing she might not be able to do it.
"Big brother? Can you do it?" she asked cautiously.
After a long while, the eldest brother finally let out a heavy sigh and nodded. "Logically speaking, you wrote it very clearly, so it should be fine, but it's too complicated."
"The furnace body and flue pipes are easy to make, but the internal structure of the furnace is complex and not easy to make. I cannot be completely sure that the goal will be achieved."
It's actually quite obscure and difficult to understand. What does it mean to bring the remaining flue gas in the return air duct back to the return air chamber for secondary combustion?
After the elder brother finished speaking, seeing that Zhiyin looked dejected, he added with a smile, "Don't worry, sister. According to what you said, once this furnace is made, it will protect countless people."
"I will definitely try my best! Oh, actually I'm exaggerating. Maybe it's not that difficult. If I try a few more times, I should be able to do it."
"Okay, thank you very much, brother! I'm sorry to trouble you."
After communicating with his confidant for a long time, the eldest brother finally felt that he had made some progress.
I couldn't wait to start trying it out.
Seeing that it was getting late, Zhiyin was afraid that Yao Yulin would worry, so she quickly prepared to go home in the dark.
"Fortunately, the sky was bright in ancient times, and the stars and moon were very bright, so you could see the road ahead clearly."
"Otherwise...tsk tsk tsk..."
As Zhiyin drove the mule cart at breakneck speed, he couldn't help but mutter to himself with emotion.
"Whoa—!!!!"
Suddenly, Zhiyin frowned as she looked at the half-lit, half-shadowed humanoid creature disappearing into the darkness ahead, and she gripped the reins tightly.
This prevented a horrific accident from happening.
