"The metal frame of the King Kong is active, and the properties of ductility, alloying, and exchange are all in some way compatible with the metal. The speed of alloys made of metals is very fast, and the speed of alloys made of non-metallic materials is very slow. ”

"Digging insects, toothed rats, and toothed wolves are active, and the active core shows signs of gradual transformation towards metal."

"The active core is the bone structure, and the bones contain calcium, sodium, magnesium, iron and other metal elements, of which the metal calcium content is the highest. Moreover, metal elements are indispensable elements in animals and humans. ”

"The activity seems to exist in the form of electromagnetic radiation, and at the same time it seems to be radioactive, and most of the radioactive elements in nature are metals, except for radon and astatine. But radon is formed by the decay of the radioactive metal radium, which then becomes the radioactive metal polonium. Astatine, on the other hand, has metallic properties, and is decayed from the radioactive metal francium to the metallic lead......"

This is the information researched by Shen Cong and recorded in the computer file.

However, the problem returned to square one, and when he first came into contact with the activity, he deduced that the activity was related to metals.

After going around in a circle, it seems that I have obtained a lot of information, but in fact, it still does not touch the essence of activity - whether the meteor shower is related to activity, and if so, what is the connection?

I don't have a clue about it.

Shen Cong decisively pressed down this thinking that seemed to have turned into a dead end.

Continue to toss the mouse: "It can be determined that although the mutation signs are relatively weak, this rabbit is indeed a mutant, but where is its active core?" ”

Shen Cong frowned and thought.

The reason why he was in a hurry to find the active core was because he couldn't find the active core from himself, nor did he find the active core from the Vajra.

This is what distinguishes him from mutated creatures such as digging worms, toothed rats, and toothed wolves.

It stands to reason that humans are also animals, and apart from developed brains, they are essentially no different from beasts. Then animals have been mutated and have produced active cores, and humans should not be an exception.

"Shouldn't I dissect the rabbit and see if there's an active core inside?"

The thought swirled, and then retreated, Shen Cong did not really slaughter the rabbit.

It's hard to catch a living mutant monster, and you can't kill it casually until you squeeze out the remaining value.

After thinking about it, Shen Cong typed a line of words in his notebook: "Plastic rabbit, a mutated rabbit, the signs of mutation are not obvious, the active core has not yet been discovered, carnivorous and there are records of eating plastic, and the specific characteristics remain to be observed." ”

Unable to learn more in a short period of time, Shen Cong put the plastic rabbit in the cage and threw it aside.

Then begin a new round of active guided repair of the Vajra.

……

Another week passed.

This period of time was spent in peace, without storms and sandstorms. No mutant monsters were attacked, and no living creatures were found.

Six hours a day for sleeping.

Nine hours were spent repairing the Kongo.

Three hours of time to learn about radio.

Two hours of time to exercise and practice slingshots.

Two hours of time for eating, reading novels, watching movies, etc.

An hour is spent navigating the surrounding geography.

There's still an hour to study plastic rabbits.

The rhythm of work and rest is very tight, and Shen Cong's execution is also very good, even in the last days, he still has strong self-discipline.

After a week and a half of repairs, the main frame structure of the King Kong was completely restored, and the outer armor was re-erected with steel spikes. If you only look at the surface, the King Kong is back to the doomsday chariot with streamlined armor and domineering might, giving people an infinite sense of security.

But in fact, the King Kong is still a showcase, and the internal circuit system and electronic components are still in a state of shutdown.

To completely repair the power system, Shen Cong expects that it will take four or five days.

Luckily, he had replenished fresh water and could stay here for a long time.

The 15A radar was also repaired, turning on the roof of the car, scouting movements around it. Shen Cong put on the Optimus Prime 1.0 active armor several times, brought an active pistol, a crossbow, a fanged dagger and other weapons, and cautiously patrolled into the distance. The farthest I walked a kilometer away, but I didn't find anything.

During his rounds, Shen Cong placed three hunting clips on the ground and used rotten toothed wolf meat as bait.

The toothed wolf meat that can't be eaten has begun to rot, Shen Cong is respectful of rotten food, except for throwing it to the plastic rabbit to feed, the others are dug and buried, and it is just a waste to be used as bait.

Looking forward to whether we can trade in the old and catch other mutated monsters, so that there will be fresh meat to eat.

However, to Shen Cong's disappointment, except for the plastic rabbit attracted by the Nutrition Express bottle, there didn't seem to be any mutated monsters nearby, only a bunch of flies surrounding the rotten tooth wolf meat bait.

"Cockroaches have mutated, are flies also mutated monsters?"

Shen Cong caught a few flies and came back, preparing to study and study, but the result was very disappointed, the flies were just ordinary flies, they were inactive, and they were not mutated animals.

But at least it brought Shen Cong a useful piece of information - not all creatures have mutated.

Then he put forward an idea: "So, if you continue to feed flies with active meat, can you mutate the flies as well?" ”

Thinking of this, Shen Cong immediately began to study with great interest.

The active content of the rotting toothed wolf meat was about to be lost, so he took out a piece of the big tooth rat meat that was not yet rotting but was fast, and threw it into the gauze cover containing the flies, which contained 5 green-headed flies.

After that, there was no more attention, and it was a difficult thing to make the activity grow, let alone produce mutations. The tooth wolf carrion was fed to the plastic rabbit for a week, and the active strength of the plastic rabbit only increased a little, and the effect was not obvious. He also felt this from himself and from the Vajra, and the increase in activity was not something that could be achieved overnight.

It takes a lot of time to complete the process of change.

……

Today is July 22nd.

The end of the meteor shower was on May 18, two months and four days after the end of the world. The total amount of activity exchanged from the Vajra, including the activity of eating mutated meat, is very limited. The activity of the King Kong has never even been finished with 100% alloy of the body.

The activity suddenly appeared with the apocalypse, there were no other survivors exchanging information, and there were not enough reference objects, Shen Cong did not know his control and absorption of the activity, whether it was fast or slow.

However, for the speed of mastering activity, Shen Cong didn't feel much pressure from the bottom of his heart, as a human being with outstanding intelligence, he was still on the edge of groping, and those monsters with low IQ and instinct could not surpass his comprehension of activity.

What's more, he still has the King Kong number.

Toothed rats, toothed wolves, burrowers, plastic rabbits, and not even the slightest threat to the King Kong.

Even in the torrential rain and water, the monster suspected of being a prehistoric giant crocodile did not completely break through the armor of the King Kong - of course, the suspected prehistoric giant crocodile still left a trace of haze on Shen Cong, and this prehistoric giant crocodile should have been mutated from an ordinary crocodile.

A crocodile can mutate into a behemoth like a prehistoric giant crocodile, so if an elephant mutates, wouldn't it be able to become a mammoth or even a monster at the level of a big dinosaur.

An elephant weighs about 3 to 5 tons, and a mammoth can have a 12-ton level, and if the elephant mutates into a mammoth level, although it is difficult to say that the 30-ton King Kong will fly up, it will really burst into impact and it is still possible to knock it down. This is enough to pose a threat to the Vajra.

"Fortunately, the elephants are all in Yunnan and Southeast Asia, and there are basically no elephants in Anhui Province...... There are more cattle breeders, and there is a Siberian tiger breeding base in Tongling......"

Thinking a little far.

Suppressing these slightly worrying thoughts, Shen Cong added another piece of rat meat to the plastic rabbit, and put the mice and flies in the corner.

Then I made myself lunch and fried a piece of rat steak.

The meat of the toothed rat is not delicate enough, the texture is rough, and the taste is not bad, a bit like small pork.

After lunch, there was an hour break. Usually he watches movies, but today he doesn't want to watch movies, turns on the music, and prepares to modify his weapon.

Slingshots, crossbows, bows and arrows, pistols, and high-pressure air guns are Shen Cong's most powerful long-range weapons, and he will also make earth bombs when necessary. Daggers, military stabs, iron forks, machetes, axes, nunchucks, and short-range weapons Shen Cong is also not lacking.

Shen Cong was full of confidence in his own firepower.

But that was before he met the prehistoric giant crocodile, the appearance of the prehistoric giant crocodile made Shen Congming confess that he was still a little too naïve, and the mutant animal may not have as much activity as him, but the body advantage is too obvious. Although the probability of encountering such a dangerous mutant animal is relatively small, you should upgrade your weapon if you are prepared.

Bang bang.

A bag of active cores was poured to the floor by Shen Cong.

Inspired by the fanged dagger, Shen Cong recognized that these active cores were needed for the upgrade of weapons.

Eleven wolf fangs, two large toothed rat front teeth, and a pair of burrowing insect chelicera.
