After cleaning up the five dead mice, Papa Jiao turned back and went into the inner room again. Not long after, he returned carrying a slightly bigger cage out.
Inside the cage were still five white mice as before, only that their sizes were much bigger.
“These are rats, the big white rats used in the laboratory are a mutated variation of the normal brown rat family.
Use the same method as before, but you need to use a bit more power, just a little more. Main thing is controlling your strength and succeeding in one strike. Do you need me to demonstrate?”
Zheng Tan shook his head.
Zheng Tan: “…”
Following what Papa Jiao had said, the rats should be somewhat harder by a teensy bit. However, after testing out the five rats, Zheng Tan had become just as proficient.
“Still need to practice?” Papa Jiao asked.
Zheng Tan shook his head.
“Good, then the rat killing practice will end here. Let me tell you…… “
Zheng Tan’s ears twitched. “…” Here we go again.
Although they had already finished killing off the rats, Papa Jiao’s teaching mode clearly hadn’t completely ran its course.
“At our laboratory, besides the commonly used execution method of snapping necks of rats and mice.
There are also other methods such as execution by chopping the head off, bleeding, beating, anesthesia, and poison gas. For amphibious species we use the marrow destroying method.
One injection is all it takes. Oh… Next week I’m teaching the zoology course on dissecting.
It just so happens that we’re dissecting bullfrogs, when the time comes, I’ll bring one home to give you a demonstration.
Oh, also, what you should especially take note of, is that execution of dogs, cats and so on in the lab are mostly by venous air embolism.” He paused for a moment.
Papa Jiao looked at Zheng Tan: “You do understand this, no?”
Zheng Tan shook his head, his muscles stiffened a bit, the hair on his back and tail stood straight up,
and he always just had the feeling that the temperature in the surroundings were quite cold.
“Simply speaking, this method is the intravenous injection of air.”
Zheng Tan broke into a shiver . This he understood. Even if he wasn’t that knowledgeable in this field, he knew what would happen from an intravenous air injection.
“Air that enters the blood circulation will arrive at the lungs, blocking the arteries in the lung and cause critical shock or death.
For example, when you swim from deep waters to shallow waters, the change in pressure will cause the air in your body to expand, which causes your lungs to expand too.
If you don’t exhale the excess gas or don’t have enough time to remove it, then things become quite dangerous. Some of the people trapped inside the Titanic when it sank have died in this way.”
Speaking up to there, Papa Jiao suddenly realized that talking about the Titanic to a cat wouldn’t be of much use.
Therefore he returned to the beginning and summarized, “ Therefore, from now on, you need to be careful, stay away from dangerous objects and pay attention to your safety.”
After learning the technique to kill rats, tonight’s goal could be considered accomplished. Zheng Tan heart also had a list of goals.
Although when it came to catching rats he was quite helpless, since he was now a cat, probably only cats that could catch rats would receive recognition.
Even the second rate Yellowy could do it. Zheng Tan believed that he could also do it.
When they returned to the eastern residences, Zheng Tan saw a car parked in the empty area on the other side. The car had a familiar looking military sign hung on it.
Speaking of which, Chubs, that guy, had also came back from his trip to his relatives.
While Papa Jiao was parking his car into the parking shed, Zheng Tan took the opportunity to jump onto the balcony of the first floor, and took a peek inside.
A packet of instant noodles was placed on the desk near the window, and squatting on top of the instant noodles was a slightly overweight Dragon Li Cat.
