Chapter 858: Developer

? "It takes more than fifteen years to train a hunting dog that can sniff the trails of the blood clan, and it also requires a living blood clan as a training object." George continued.
"This is not the most troublesome thing. After the vast majority of hounds smell the peculiar smell of the blood race, they will hide as far as possible due to the characteristics of biological advantages and avoid harm. At least a few hunting dogs This smell will be tracked-this kind of hounds generally have a certain defect in their genes, and it is this'defect' that makes them no longer afraid of blood."
"My father used to have such a hound, but when I was five years old, this old hound that could no longer be old was already dead... But fortunately, I invented the'developer' even if it was This is also an extremely important invention in the family history of the Hasings for thousands of years."
　　 "The developer? Is it the kind of thing used for old-fashioned film photos? Isn't that something that has existed in the last century? You are ashamed to say that you invented it?" Qi Lin said.
"I just borrowed this name. In addition to the silver halide in the ingredient list, my'developer' and the developer used to wash photos are completely different things. The'shadow' it can show is the blood family. Traces." George said confidently.
　　 "Well, I will believe you for a while, I hope your'developer' can come in handy..." Qi Lin glanced at George's list again and said.
Fortunately, Refuge No. 209 is at least a medium-sized refuge, and its position in the underground refuge network is pretty good. It is located on a branch line of a major transportation artery. Although these chemical reagents are difficult to obtain, but It is not completely impossible.
　　 If this is placed in some remote place, I am afraid that half of the items on the list will not be included.

This torture room borrowed by Qi Lin has become a chemistry laboratory. The interrogation table was dragged to the center of the room, filled with glassware containing various chemical reagents, beside the table. On the other hand, a large ceramic crucible was placed, and the crucible was filled with various dark and unidentified reactants.
　　 At this moment, George is lying on the ground, holding a long-necked flask with an asbestos glove in his left hand, and holding a flame spray gun in his right hand, carefully heating the mixture in the flask.
　　 "Boom!!"
　　 The flask suddenly exploded, and George had already pulled a metal plate on his side first, and quickly protected his body behind the metal plate.
　　 The glass shards hit the metal plate, making a crisp clash.
"Can you do it... This is already the sixth flask that you bombed..." Qi Lin and 0592 watched from a distance in another corner of the room-at first they wanted to be close. Observed, but when the second explosion occurred, the two had already dispelled the idea.
　　George himself is controlling the experiment process. He can predict when it will explode, but Qi Lin and 0592 cannot. When the first explosion happened, the sharp glass even directly pierced 0592's eyes.
　　 Fortunately, they are a pair of mechanical eyes. The cornea is polished with high-hardness quartz and covered with a transparent metal coating. If it is replaced with a pair of naked eyes, I am afraid that I will be blind.
　　 "It's not a big problem..." George waved his hand, and took out another flask that was tightly wrapped in cardboard from the travel bag on the side.
　　 "Are you not a big problem? Is it a big problem only if you are killed?"
"Uh... the spirit of science is not to be afraid of failure, right?... To be honest, this'developer' was actually invented by me accidentally. As for the production process, it is still in the process of perfection... First of all, the temperature of the flame is very important. The temperature of the spray gun is difficult to stabilize and cannot meet my requirements..."
　　 "The temperature is stable? This is easy to do. How high do you need to be?" Qi Lin asked.
　　 "This step requires melting the silver, at least 960 degrees Celsius."
"OK, Cortana, hand it to you." Qi Lin snapped his fingers, and Thor's Hammer stepped up, drew out a thermal axe, and placed the axe face across in front of George. The color of the noodles began to gradually redden, and the surrounding temperature gradually rose.
The 　　 thermal axe is not only used as a weapon to break armor, but the electric baking pan is also easily competent. On the front line, Qi Lin has seen armored soldiers use thermal axes to heat food.
　　 "Cortana, what is the surface temperature of the thermal axe now?"
　　 "962 degrees Celsius."
"That's okay?" George was stunned, but he quickly entered the state, pouring the new reagent on the surface of the thermal axe. On the surface of the thermal axe, there are several oval shapes. The grooves of these grooves are similar to the blood grooves on the dagger, in order to guide the molten metal liquid along these grooves when the thermal axe cleaves the metal armor.
　　 The finely divided silver nugget quickly began to melt after falling into the groove. Then, George poured other solutions that had been prepared long ago, and stirred it gently with a quartz rod.
　　 "It's alright, cool down! Cool down!"
　　 "How much is it down?"
　　 "It drops to 350 degrees Celsius first~EbookFREE.me~slowly and rapidly."
　　George stared at the mixture in the groove of the axe face, and when the state of the mixture gradually stabilized, he spoke again: "From now on, it takes 30 seconds to bring the temperature down to room temperature, but it still has to drop quickly."
The surface of the thermal axe gradually returned to its original metal color, and the mixture in the groove also condensed into a gray solid substance.
　　 "Is this your "developer"? Is this a success?"
　　 "It succeeded—" George said happily, using a dagger to pry the solidified reactant out of the groove, and then throw it into a large beaker full of purple liquid on the table.
　　 As soon as the reactant touched the purple liquid in the beaker, it immediately began to dissolve, and at the same time a large amount of gas emerged from the liquid.
　　George quickly grabbed the sealing cap and placed it on the top of the beaker, then Qi Lin and 0592 said, "Quickly, we have to go to the car that happened. The shelf life of this thing is not long!"

The three people and Thor’s Hammer quickly rushed to the carriage where the assailant’s body was found. George used an awl to poke a hole in the sealing cover of the beaker, and the gas inside quickly gushed from the hole. come out--
　　 After this gas diffused into the air, gradually, a trace of purplish red was revealed, and this trace extended from the bathroom to the outside of the carriage.
　　 "After the'developer' volatilizes, it will combine with the special smell left by the blood in the air, turning the colorless gas into purple. Using this clue, we can find the blood!" George said.
