Departing from the nice acolyte, Vin continue with his plan. After fifteen minutes of walk, he arrived in Serabough Market Center, the most bustling location in the whole city.

"Hello Uncle! Do you have any egg, salt, baking soda, milk, and butter?" said Vin, waving his hand back and forth.

"Certainly! How much do you need, young man?" replied the merchant with a smile, silently calculating possible profit to be "gained" from the boy.

"A dozen egg, two bottles of salt, two bottles of baking soda, a glass of milk, and five slices of butter!"

"That would be Three Silvers and Fifty Coppers." said the merchant.

"Okay, here you go!"

"And here your grocery, come again!"

Excellent..

"Excuse me, are you the blacksmith here, sir?"

"Yes, that's me. What do you want?"

"Do you have any iron, sir?"

"Of course I have Iron! What you take me for? I'm a blacksmith you know!"

"Umm, I need iron dust, with just a little bit of copper in it. Could you make it sir? The smaller the dust, the better!"

"Iron dust he? I never see any people interested in that, I've a lot of it. Comes from sharpening the blade all the time, wait a minute. WARREN!" shout the blacksmith.

*tap tap tap tap* A teenage boy ran down from the upper stairs. He was sweating. Profusely. From his attire, this boy must be the blacksmith's apprentice. Apprenticeship were never easy, Vin thought. You must do everything your master said. Of course there are nice masters, but most of master were nice and demanding master, the one who thought the best way to teach apprentice were let them experience the hard work in life continuously. A glance to the boy expression, people could say, he got the latter type of master.

"Sweep the iron and copper dust from the sharpening room and give it to this customer! Chop-chop! I don't have all day, and you still have your unfinished job!"

"Okay, master." said the boy dejectedly.

After fifteen minutes of laborious sweeping.

"Here your iron and copper dust, Mr. customer." said the tired apprentice, giving him two jars of the dust. It seems if his master weren't looking, he would collapse to the floor in instant.

"Umm.. How much is it?" Ask Vin.

"Well, we don't usually sell the dust, let's see, how about I weigh it, and you pay the normal metal price in weight, plus the grinding cost?"

"Hmm, okay."

"That would be 30 silvers and 40 Coppers."

"That's too much! How about 25 silvers?"

"30."

"26 and I would praise your good job in front of your master."

"29 and fifty coppers, and I'll put you in our regular customer list."

"27, that's if you don't mind to be mean to a young child."

"28 and fifty coppers, and that's if you don't mind to deem my labor's free."

"Deal!"

"...."

Back to the laboratory. Vin begin to conduct his plan.

"There is no way, I'm going to give my blood to that imp! 100 ml is a lot! I going to get anemia! And possibly tetanus from making cut in my vessel! This medieval age don't come with sterilized syringe don't they?" complained Vin.

Vin began to boil the water and prepared the salt and baking soda. Next, he carefully weigh the needed amount. He put salt and and the baking soda to the buffer phosphates. After careful inspection, he crack some of the eggs and separate the white from the yolk, adding the white to the milk.

"Now, now, don't precipitate... this age don't came with emulsifier... Well, yolk is emulsifier, perhaps.."

He took a cup of salt solution and added to the cup of white-milk, added with lots of yolk into the mortar. As he began to stir, he added sprinkle of iron and copper. He frowned, seeing the iron still comes in it's powder form, floating in the surface of the emulsion, well of course he knew he should reduced it first into solutes form, then again, it's not worth the effort.

"Red color of the blood comes from the iron, and no, this lab doesn't came with protein sequencer.. A bit of red lipid-soluble dye, should do the trick, I hope..."

Ten minutes later, after heavy stirring. He finally created the gooey-looking red substances.

Vin draw the reversed-shaped star using the artificial blood in the piece of scrolls. Then he pour mixed of salt and sand around the scroll and sprinkle it with holy water.

"Under the blood-strengthen Contract, I summon thee from the hell itself, Come to my assistance. O little child of darkness!"

The star diagram glowing brightly, Vin could feel most of his mana sucked dry to the spell. A red smokes raised from the magic diagram. He had summoned the imp!

"Ha haha! Foolish Mortal! Dare to summoned me when you're so weak! Now I'll wreak this who---*thump*"

"What is this! You dare to imprison me mortal?"

"It's only salt-sand barrier, the most basic barrier. I'm fully aware the book never said you will obey me. So I took a little precaution." said Vin nonchalantly.

"How dare you! Take this, fire ball!" said the imp releasing fireball from his hand. However the fire simply dissipate when it touch the barrier.

"What? No matter! Teleport!" shout the imp, red light glow from his body, but after a while the light flicker, and disappear.

"Now, Now, Mr. Imp, would you be my colleagues?"

"No! Why should I?! You're nothing but a weak mortal!"

"Well this weak mortal had managed to trap you."

"It proofs nothing!"

"And this weak mortal coincidentally able to produce lots and lots of blood, I could simply continue to pour the blood to your diagram, and you have to stay there, indefinitely."

"...."

"Here let's me show you."

Vin made another batch of Lesser Artificial Blood.

"See, Mr. Imp, you could just stay there, like I don't know? Five-ten years? My research required a lot of effort you see. And I currently looking of capable help to quickening the process."

"...I concede."

"Great! Let's me set up the contract for you!"
