Reborn as a Cube Man in the Late Ming Dynasty

Yan Chengren and the others rushed over, where Bai Li had been waiting for some time. He raised his hand as if he had expected this: "You want to ask about the medicine, right?"

Yan Chengren was still catching his breath: Young Master Bai already knew all along. That's right, he came here precisely for this matter.

Bi Zhengcheng was panting heavily, but he didn't delay. He pushed the cart to Bai Li and said, "Young Master Bai, all the medicines my master made are here. Please take a look."

Bai Li took the potion and poured it in: "Underwater breathing, fire resistance, slow descent—the effects of the first two are self-explanatory. The slow descent effect will prevent you from taking damage no matter how high you fall, and will also slow your descent speed, provided you are within the potion's effective range!"

Bai Li explained the effects of the medicine, while Yan Chengren took notes.

The main attraction is the potion made from slime.

Bai Li drank it and checked the status bar.

"Groin seepage, what kind of effect is this?" Bai Li muttered to himself.

He couldn't guess the effect just from the words.

He took the last bottle of potion from the box, added gunpowder to the brewing table in the workshop, and turned it into a splash potion.

Carrying the bottle, I left the cabin and went around to the small pasture in the backyard.

The potion was thrown out and splashed onto the chicks. Bai Li swiftly killed the nearest one. The dead chick had just turned red and lay down when two round, semi-transparent green objects—medium-sized slimes—suddenly jumped out of thin air next to its corpse.

Bai Li suddenly realized: So that's how it is.

He chased after the chicks with a stick and hit them, observing their reactions after being hit.

After testing it two or three times, he figured out the true effect of the medicine.

Once a creature is afflicted with this status, it will attempt to spawn two medium-sized slimes at the site of its death.

Bai Li couldn't suppress the smile on his face. He pulled out his diamond sword and killed all the chicks, and also dealt with the slimes scattered all over the ground.

He was quite satisfied with the thirty-one slime balls inside his backpack.

A sticky ball is needed to tie a rope, although the demand for tying ropes is not high at present.

But none of that matters. The most important thing is that the sticky piston and the slime block, two core materials of Redstone technology, both rely on slime balls.

Previously, he could only occasionally collect one or two from those weak pandas by chance, but now he has this bottle of potion.

Killing a chicken breeds slimes, killing a slime produces slime balls.

Anyway, the number of chickens consumed in Licheng every day is not small. After using a bottle of potion, there is no shortage of slimes.

This production line has been revitalized.

Yan Chengren witnessed the entire process.

He hesitated before speaking: "This potion can actually create demons out of thin air?"

Yan Chengren looked at the new monster and the slime ball it exploded out, and thought of the spider eye he obtained from the spider, the ender pearl on the enderman, and the immortal light refined by the great monster.

A completely new idea popped into my head.

After these monsters die, do they all leave behind extraordinary treasures?

The thought had just crossed his mind when he forcefully suppressed it and stopped thinking about it.

Bai Li then asked: "Besides the ones I just mentioned, have you made any other potions?"

Yan Chengren composed himself and replied: "There are medicines that can make people as light as swallows and leap several feet, medicines that can make people as fast as the wind, medicines that are poisonous and corrosive, and medicines that can increase strength."

Bai Li said, "Jump Potion, Swiftness Potion, Strength Potion, and Poison Potion, you know."

Yan Chengren then added the name of the medicine to it.

Bai Li said: "Make a batch of this seepage potion first. Make more strength potions, you'll need them later. Also, make some poison potions. After you've made them, add gunpowder to make them spray-type. Just keep making them. Someone will come looking for you tomorrow."

The seepage potion was delivered to the Red Stone Chicken Factory, while the highly toxic potion and the strength potion were placed in a box next to the Li City teleportation device.

Yan Chengren: Understood.

Having given all the necessary instructions, Bai Li's gaze fell upon Feng Yuanzhen, who had been standing quietly to the side.

Feng Yuanzhen bowed and said: Young Master Bai?

Bai Li smiled and said, "Feng Yuanzhen, you have been practicing external alchemy for decades. I have a question for you."

Young Master Bai, please speak.

Bai Li pondered his words: Some things, when dripped onto stone, will bubble and erode the stone, leaving pits; when sprinkled on copper or iron, they can turn into green liquid. And some things have the exact opposite properties; they become slippery and hot to the touch when they come into contact with oil, but they can neutralize the corrosive properties of the former.

In all these years of alchemy practice in your Taoist sect, have you ever seen anything like this?

Feng Yuanzhen frowned and pondered for a moment before slowly speaking: "If what Young Master Bai is referring to is something that can corrode gold and melt stone, I have indeed seen quite a few. The most common one is the juice obtained after calcining alum, which is potent and can corrode bones and melt iron."

Bai Li raised an eyebrow: How did you get it?

Feng Yuanzhen gestured with his fingers, indicating the name: Take green vitriol, also known as ferrous sulfate, and put it into an earthenware pot, then calcine it over a strong fire. When the vitriol changes color and oily droplets are released, guide the gas through a bamboo tube, condense it in an earthenware pot, and the resulting clear liquid is alum oil. If this substance is dripped onto copper or iron, it will instantly produce white smoke, and ironware will be pierced.

"This method was recorded by Gu Gangzi in the Tang Dynasty in the 'Huangdi Jiuding Shendan Jingjue'. In those days, it was mostly used to refine copper and iron, and very few people collected this liquid separately."

"The opposite of what you mean, Young Master Bai, is alkaline, isn't it? If you mix lime and straw ash with water, the resulting liquid will be even spicier and can rot flesh and corrode other things."

Once Feng Yuanzhen started talking about alchemy, he couldn't stop, gesturing rapidly with both hands.

Bai Li keenly noticed that this person was missing a little finger on his right hand.

What happened to your finger?

Feng Yuanzhen revealed his broken stubble: It's embarrassing to say, but years ago when I was refining a batch of Golden Elixir Pills, I ground sulfur powder on the first day and got my hands covered in yellow powder.

Back then, I was young and thought it was just some dust. I just patted it off and that was it, without even rinsing it with water.

The next day, when the furnace was turned on and saltpeter was added, the powder was pinched between the fingers and fed into the furnace. With a whoosh, the hot air in the furnace shot up and the lid was blown off.

The shards slashed towards him, and his little finger didn't have time to retract. Feng Yuanzhen said earnestly, "From then on, I feel uneasy if my hands aren't clean. The lesson I learned from that finger is something I'll remember for a lifetime."

"Are you still afraid of alchemy?" Bai Li suddenly asked.

Fear? As long as I can refine a true elixir, I'd gladly give my life. "To hear the Dao in the morning is enough for me to die in the evening!" Feng Yuanzhen said.

Bai Li got the answer she wanted and smiled, "Alright, if you succeed in your transformation, I'll teach you another external alchemy technique."

"Chemical!"

"You won't have to wait long; the job change will happen in the next three or four days!"
