The chelicerae of the digging insect resembles a sickle, the palm is long, and it is not sharp to the touch, but once it is injected, it can barely achieve the effect of sharpening iron like clay, and the steel plate can be cut out by slashing hard.

Fortunately, the burgering insect was estimated to not be able to use the activity at all, so when it bit the iron hook, the chelicerae did not have an effect.

However, driven by instinct, mutant monsters will sooner or later learn to use their activity and become more difficult to deal with.

"The chelicera is only the length of a palm, and the machete is smaller, and if you make a dagger, you will have teeth and fangs, and it will be redundant."

For the chelicera of the digging insects, after thinking about it, Shen Cong felt that there was no suitable transformation plan.

Shelved for the time being.

He grabbed the front teeth of two large toothed rats, which resembled straight watermelon knives, one and a half fingers long, slightly flattened and curved, with a clear cut at the tip. This shape is more suitable for transforming into military thorns, but compared to the sharp teeth and wolf fangs, the incisors of the large-toothed rat are not too good materials.

"It's a good idea to make a small pickaxe."

The pickaxe was not in a hurry to use, and Shen Cong chose to put his front teeth on hold as well.

In this way, only eleven fangs are sufficient. For the fangs of the toothed wolf, the best role that Shen Cong thought of was to create a dagger, and the previous fanged dagger was very handy. However, there is no need to make too many fangs and daggers, the fangs are very strong and durable, and they are difficult to wear easily.

"You can do javelins, but there are some bends that need to be polished."

The power of the javelin is still very great, with Shen Cong's strength and a half, after injecting the activity, it is thrown out, I believe that even the monster suspected of being a prehistoric giant crocodile will have to be broken and hit hard.

He needs such a deterrent heavy weapon.

The fangs have a curved arc, the javelin has good requirements for the tip of the gun, the curved fangs have greater wind resistance, and the flight trajectory is also unstable. So you need to grind the curved tip of the fangs into a straight tip,

Shen Cong made a comparison with a ruler and found that he needed to grind off about the length of two knuckles.

"The length of these two knuckles, if you use a saw to cut off first, and then waste it, you can make arrowheads. Crossbow arrows and bow arrows, replacing the arrows of this active core, will definitely be more lethal. ”

After conceiving it, Shen Cong immediately decided to build eight javelins and eight arrows first.

The remaining three fangs are reserved for the transformation of the Optimus Prime 1.0 active armor, which has the fangs as the active core, and the efficiency of use is greatly improved, and Shen Cong hopes to be able to transform it more perfectly. This is also the reason why he named the active armor Optimus Prime 1.0 in the first place.

With Optimus Prime 1.0, it means that there will be upgraded versions such as Optimus Prime 1.1, Optimus Prime 1.5, Optimus Prime 2.0 and so on.

The upgrade of the active armor involves a lot of ideas, which needs to be carefully considered and can be postponed.

Shen Cong first sharpened the javelin spear tip and arrow arrows.

As a folk expert who can even DIY the doomsday chariot, Shen Cong picked up the electric grinder and immediately began to cut the first fang. The hardness of the fangs without inactive injection is about the same level as carbon steel, and under the constant friction of the grinding wheel, countless pieces of powder are flying.

Shen Cong, who was wearing an eye patch, his hands were very stable, and he cut off the front end of the fangs little by little along the drawn cutting line.

After cutting, the two-finger-long tip is set aside and the fangs are sharpened. Grinding shapes with an electric grinder is a technical job, and it is not a perennial deal with it, and there is no way to grind out the ideal shape. Shen Cong is just an old driver, six years of DIY, all repairman skills, honed to the top.

After grinding into a standard spike shape, polishing it, and then cutting the root in half along the midline, the javelin tip is made.

The handle of the gun is easy to do, a steel bar, the front end is also cut in half along the midline, and then polished to match the shape of the tip of the gun.

Buckle it, open two holes, pass it through with a steel wire, and then wrap the steel wire around it. Then the steel wire is melted off with electric welding, and it is melted into a circle of iron sheets, and the buckle connection is wrapped. A simple javelin is made.

Of course, this javelin has not yet been calibrated, and it still needs to be finely polished, and it is better to have a few blood grooves on it, so that the lethality is greater.

I looked at the time, and the hour's rest passed.

Shen Cong moved his body, put down the javelin, walked to the wheelhouse, and began to repair the King Kong for nine hours a day. All work is secondary, repairing the King Kong is the first priority, if not for the limited energy, he even hopes to spend 24 hours a day on repair.

Part of the power supply system has been repaired, the main frame structure has been repaired, the external armor has been repaired, and in the next step, Shen Cong plans to repair the power system.

……

Another day passed, July 23, 2022.

was supposed to continue to live a regular and monotonous life, but there was a slight change, and the plastic rabbit that was raised by Shen Cong and ate and drank all day long began to become abnormal.

At first, it was constantly circling in the cage and cooing, but Shen Cong didn't care, just threw a piece of the rotting big-toothed rat meat into it.

But the plastic rabbits, who usually eat frantically when they see mutant meat, ignore the big-toothed rat meat this time, and are still irritable in the cage.

"In heat?"

Shen Cong did not have a malicious guess, and then studied for a while, but did not come up with useful information.

Compared with real scientists, Shen Cong can only simply record and analyze, and there is not much information that can be studied, so he wants to dissect the plastic rabbit and carefully find the active core.

Holding back this thought, Shen Cong didn't care if the plastic rabbit was in estrus or not.

It's just that in the afternoon, it's hard for Shen Cong not to pay attention, the plastic rabbit is no longer satisfied with the irritable circle, and even began to hit the iron cage with his head, tearing the steel bar with his teeth, and seems to be desperate to leave the cage, which has not happened before. The plastic rabbit that is put in the cage is very quiet as long as it eats and drinks contently.

Shen Cong speculated that the plastic rabbit may have been mutated by captive-bred rabbits, and its personality would be slightly docile.

Now apparently the plastic rabbit has a red eye.

"There shouldn't be such a big movement in estrus." Shen Cong frowned and thought, he didn't know much about the behavior of animals, let alone the mutated animals.

But after observing for three minutes, he keenly discovered a phenomenon, the direction of the plastic rabbit hitting the iron cage is the same place, close to the side of the carriage wall.

Shen Cong also thought that the IQ of the plastic rabbit had risen, and he wanted to specialize in it.

So he quickly lifted the cage up and spun around in an attempt to interfere with the plastic rabbit's sense of direction - even though the plastic rabbit did not have many signs of mutation, it could not cause damage to the iron cage at all.

The plastic rabbit that turned around, and sure enough, there was a judgment error, and he hit the place close to the wall of the carriage again, but it was no longer the original side.

"Huh?"

This should have been funny, but Shen Cong didn't laugh, because he found that he had made a mistake in his judgment just now, and the plastic rabbit didn't want to specialize in a little bit and then escape from prison.

The plastic rabbit is always rushing in one direction, north-northwest.

Shen Cong turned the cage around repeatedly, and the impact direction of the plastic rabbit was north-northwest.

It's as if there's something north-northwest, attracting plastic rabbits, and it's a strong attraction. The plastic rabbit's head had been hit to the point of bleeding, and it was still hitting unrelentingly.
