Yuan Tiangang casually gave his instructions and then turned back into his room.
The old Daoist had already made arrangements; they would do their best to concoct these divine items for the young friend.
Concoct, divine items. Hearing these words, Fang Er couldn't help but give Yuan Tiangang a thumbs-up.
A divine con man is a divine con man! Listen to how grand these terms sound!
True Master Yuan, your subordinate here says, how about you use sulfuric acid and nitric acid, these two divine waters, to prepare another new divine water?
Fang Er pointed to the jars by the wall and said.
Very good, very good! Young friend, please elaborate.
Old Yuan was very curious about what kind of substance would be created. He walked to the jars and waited quietly for Fang Er's preparation method.
Take one part nitric acid and three parts sulfuric acid, mix them together. Be careful, pour the sulfuric acid into the nitric acid, otherwise, it will be dangerous.
Pour while shaking the jar to ensure they mix thoroughly and dissipate heat.
Fang Er said, stepping back a couple of steps.
Mm, the doorway should be safe enough.
Although it was unlikely that anything would go wrong, his own life was still paramount.
Yuan Tiangang didn't notice Fang Er's actions at all. After hearing his words, he picked up an empty glass jar, opened its mouth, and according to Fang Er's instructions, poured the nitric acid and sulfuric acid into it.
Fang Er stood by the doorway, watching Old Yuan's actions. The entire jar, containing at least dozens of pounds of concentrated nitric acid, was lifted by him as if he were pouring water from a bucket. With a whoosh, it was poured into the empty jar on the ground.
Damn, this method of operation was too unrestrained, making Fang Er's heart pound.
As Old Yuan put down the nitric acid jar to fetch the sulfuric acid, Fang Er quickly shouted from the side, True Master Yuan, be sure to pour slowly!
Old Yuan turned his head, revealing his four remaining golden teeth, and smiled at Fang Er, Hahaha, young friend, rest assured, this old Daoist knows what he's doing.
Fang Er:
You're talking to me while pouring and turning your head, it doesn't look like you know what you're doing at all!
Look, I'm impressed!
It's splashing outside the jar!
Old Yuan, like a nimble old ape, continued pouring with the jar in his hand, shuffling his feet to avoid the splashing acid.
Fang Er felt a bead of sweat on his behalf.
Soon, the mixed acid was prepared by Old Yuan in this simple and crude manner.
Old Yuan put down the sulfuric acid jar, stroked his newly grown beard, and said with a grin.
Young friend, what's next?
Fang Er walked over cautiously. Mm, it's mixed, there shouldn't be any more problems, right?
Feel the jar, is it hot?
Old Yuan heard this, reached out and touched the jar, Huh, it's still warm!
Fang Er's steps halted, Then wait, wait until it cools down.
After saying that, he sat down on the threshold, took out a Hongqiqu cigarette, lit it, then took out a cigar and offered it to Old Yuan.
Yuan Tiangang felt the jar again, then walked over, took the cigar, and sat beside Fang Er.
Here, young friend, lend me a light.
Fang Er took out a "never-ending" match and handed it over, Here, it's for you.
The silver-gleaming stainless steel casing captivated Old Yuan. After lighting his cigar, he began to study the "never-ending" match.
This thing is so magical! This old Daoist must see what kind of Daoist technique it is.
After saying that, he placed the cigar in his mouth and with nimble fingers, began to disassemble the "never-ending" match.
Those dry hands, I don't know how they became so agile. In just a few moves, he had disassembled the "never-ending" match into parts.
What the heck, is this the speed of a seventy-year-old virgin?
After carefully examining each part, Old Yuan reassembled the "never-ending" match and returned it to Fang Er.
This old Daoist has comprehended this Daoist technique. Later, this old Daoist will make one himself.
Fang Er:
Alright, thinking about the principle of the "never-ending" match, Fang Er could accept that he figured it out so quickly.
This thing, put simply, is a steel rod with a cotton wick inside. One end of the wick is dripped with kerosene or gasoline, and the cotton wick is ignited by sparks generated from the friction between the steel rod and flint.
The old and the young, one Daoist and one layman, squatted on the threshold, puffing smoke for a while. Then, Old Yuan extinguished the butt of his cigar on the ground and walked towards the jar.
He reached out and felt it, It's cool now.
Fang Er extinguished his cigarette butt and walked over with the cotton.
He threw clumps of de-seeded cotton into the jar, stuffing them in while using a glass rod he found nearby to poke them down.
He stopped when the mixed acid only left about one centimeter of liquid surface.
After finishing, he covered the mouth of the jar and packed the remaining cotton, Alright, wait for two kezhong.
Old Yuan stuck a small stick into the ground outside the door and calculated the time by observing the movement of the shadow.
Fang Er secretly pulled up his sleeve and glanced at the military watch on his wrist, noting the time.
They stood there waiting dryly until Old Yuan stood up from the ground, Two kezhong have passed!
While Old Yuan wasn't paying attention, Fang Er glanced at his watch again. Damn, the countdown had thirty seconds left. This old Daoist is amazing!
Using the previous glass rod, he painstakingly fished out the treated cotton piece by piece. He took them to the courtyard outside and rinsed them with clean water until no significant sour smell could be detected.
Then, he prepared a jar of dilute sodium carbonate solution and directly heated the glass jar. He placed the washed cotton into it and boiled it. After another two kezhong, he fished them out and rinsed them with water again.
After washing, he soaked them in a 2% potassium nitrate solution. After soaking, he squeezed out the excess liquid and placed them in the courtyard to dry.
It took a whole day to finish processing this packet of cotton, but then Fang Er was stunned.
One more item was missing: Diphenylamine alcohol.
ps: Fifth update, I love you all, muah.
