Wasteland Survival Code

Chapter 840 Developer

"It takes more than 15 years of training to train a hound that can sniff blood traces, and it also needs a live blood dog as a training object." George continued.

"This is not the most troublesome thing. After the vast majority of hounds smell the unique smell of the blood race, they will try to hide as far as possible out of the characteristics of creatures seeking advantages and avoiding disadvantages. At least a very few hounds will This scent will be tracked-the hounds generally have a certain genetic defect, and it is this 'defect' that makes them no longer afraid of the vampire."

"My father once had such a hound, but when I was five years old, the old hound that couldn't grow old was dead... But fortunately, I invented the 'developer', even in the In the thousands of years of family history of the Haixin family, this is also an extremely important invention."

"Developer? Is it the kind used for old-fashioned film photos? Isn't that something that existed in the last century? Are you ashamed to say that you invented it?" Qi Lin said.

"I just borrowed this name. Except that there is silver halide in the ingredient list, my 'developer' is completely different from the developer used to develop photos. The 'shadow' it can show is the blood traces." George said confidently.

"Well, I'll trust you for a while, I hope your 'developer' can come in handy..." Qi Lin glanced at George's list again and said.

Fortunately, shelter No. 209 is at least a medium-sized shelter, and its location in the underground shelter network is not bad. It is on a branch line of a main transportation road. Although these chemical reagents are difficult to get, they are It is not completely impossible.

If this is placed in some remote place, I am afraid that even half of the items on the list will not be available.

……

……

The torture room borrowed by Qi Lin has suddenly turned into a chemical laboratory. The interrogation table was dragged to the center of the room, and it was filled with glassware containing various chemical reagents. Beside the table, On the other hand, there is a large ceramic crucible, which is filled with various dark and unknown reactants.

At this moment, George was lying on the ground, wearing an asbestos glove in his left hand, holding a long-necked flask, and holding a flame gun in his right hand, carefully heating the mixture in the flask.

"Bah!!"

The long-necked flask suddenly exploded, and George had already pulled over a metal plate beside him first, and quickly protected his body behind the metal plate.

The shards of glass hit the metal plate, making a crisp crashing sound.

"Can you do it... This is already the sixth flask you have blown up..." Qi Lin and 0592 watched from a distance from another corner of the room—at first they wanted to get up close Observing, but when the second explosion happened, the two of them had already dismissed 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 slag even pierced 0592's eyes directly.

Fortunately, those were a pair of mechanical eyes. The cornea was polished with high-hardness quartz and covered with a layer of transparent metal coating. If they were replaced with a pair of naked eyes, they would probably be blind.

"It's not a big problem..." George waved his hand, and took out another long-necked flask tightly wrapped in cardboard from the travel bag beside him.

"Isn't this a big problem for you? Is it a big problem only if you are killed by the bomb?"

"Uh... the spirit of science is to not be afraid of failure, isn't it... To be honest, I invented this 'developer' by accident. As for the production process, it is still in the process of being perfected... First of all, the temperature of the flame is very important, the temperature of this spray gun is difficult to stabilize, and it cannot meet my requirements..."

"The temperature is stable? This is easy to handle. How high the temperature do you need?" Qi Lin asked.

"This step requires melting the silver, at least above 960 degrees Celsius."

"OK, Cortana, I'll leave it to you." Qi Lin snapped his fingers, Thor's Hammer immediately stepped up, pulled out a thermal axe, and laid the ax face in front of George. Immediately afterwards, the ax The color of the face began to gradually turn red, and the surrounding temperature also slowly increased.

In addition to being used as a weapon to break through armor, the thermal ax can also be easily used for the task of the electric baking pan. When he was on the front line, Qi Lin had seen armored soldiers use thermal axes to heat food.

"Cortana, what's the temperature on the surface of the heat ax right now?"

"962 degrees Celsius."

"That's okay?" George was stunned, but he quickly entered the state, and poured the new reagent on the surface of the heat axe. On the surface of the heat axe, there were several oval lines. The function of these grooves is similar to the blood grooves on the dagger, so that when the heat energy ax chops the metal armor, the molten metal liquid will be guided out along these grooves.

The fine pieces of silver began to melt quickly after falling into the groove. Then, George poured in several other solutions that had been prepared earlier, and stirred it gently with a quartz rod.

"Okay, okay, cool down! Cool down!"

"How much?"

"First drop to 350 degrees Celsius, and then drop slowly and at a constant speed."

George stared at the mixture in the groove of the ax face, and waited until the state of the mixture gradually stabilized before he spoke again: "From now on, take 30 seconds to lower the temperature to room temperature, or drop at a constant speed."

The surface of the thermal ax gradually returned to its original metal color, and the mixture inside the groove also condensed into a gray solid substance.

"Is this your 'developer'? Is this a success?"

"Success, success—" George said happily, using a dagger to pry the solidified reactant out of the groove, and then threw it into a large beaker filled with 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 came out of the liquid.

George quickly grabbed the airtight lid and put it on the top of the beaker, then Qi Lin and 0592 said: "Quick, we have to go to the car where the accident happened, the shelf life of this thing is not long!"

……

……

The three of them and Thor's Hammer quickly arrived at the compartment where the victim's body was found. George used an awl to poke a hole in the sealing lid of the beaker, and the gas inside quickly gushed out of the hole. come out--

After the gas diffused into the air, a purple-red trace gradually appeared, 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 vampire in the air, turning the colorless gas into purple. Using this clue, we can find the vampire!" George said.
