My skill in becoming a god is landmine mastery.

Well, if he can't do anything else, then so be it. Seeing that the landmine mastery skill also showed some potential, Yang Yao didn't say anything more.

Returning to the topic of landmines, this particular type was indeed very suitable for Yang Yao.

It wasn't just because he hadn't yet synthesized trinitrotoluene and lacked the materials to make the N9 surface-to-air mine; more importantly, he needed something to save his life.

The ejected armored fragmentation mine is such a thing. Although Yang Yao's physical strength is now stronger than that of an average person, even a peanut might be enough to knock him down twice.

Compared to attacking, hmph, only by surviving can one have the opportunity to attack.

Although the Mine Mastery skill provided him with a mature method for making landmines, Yang Yao still needed to make some minor adjustments to better suit its use in this world.

However, for Yang Yao, whose intelligence is quite good, these were still relatively easy tasks.

The skill "Landmine Mastery" not only gave him methods for making several types of landmines, but also included various technological techniques. This was what made Yang Yao most happy.

In this way, one can also use these technological means to create other props, not just landmines.

The ejected defensive armor-piercing landmine that Yang Yao is currently developing operates by calculating surrounding hazards through a program and connecting them to a thruster that forms the landmine's outer shell, thus creating an abstract landmine backpack for defense.

That's right, it's an abstract landmine backpack. It's much larger than a regular landmine, about the size of a well cover. The effectiveness of the landmine depends on the precision of the chip, the strength of the program's recognition capabilities, the operating speed of the thrusters, and the material strength of the outer shell plates.

The equipment was placed on his back, but in Yang Yao's opinion, it was the shell of a Teenage Mutant Ninja Turtle!

However, the one Yang Yao made was at best a budget version of this landmine. Originally, the power source inside the armor plates of the landmine shouldn't be a thruster, but an intelligent mechanical core, which would allow for more precise and faster defense.

But we don't have that, we're not rich, we can't afford such expensive stuff, a thruster is fine!

There are many energy options for landmine propulsion systems, and Yang Yao chose liquid hydrogen, a substance that makes up 70% of the universe. It is also a suitable energy source and is environmentally friendly.

At the same time, a miniature helium conversion device was added inside the thruster, giving a fully defensive landmine an additional means of attack.

It wasn't that he didn't want to use electricity, but the battery life was really poor. Yang Yao could make compressed batteries by hand, but he lacked the materials, and charging them was a huge hassle.

While extracting liquid hydrogen is not as convenient as using electricity, it has the advantage of a longer operating time. For this purpose, Yang Yao even secretly connected an electric wire to the power switch in the residential area under the cover of darkness to extract hydrogen.

For the time being, Yang Yao didn't need to worry about the battery exceeding its limit and attracting attention. After all, this wasn't his world, where there were far fewer security cameras.

This not only provides it with fuel for its own propulsion system, but more importantly, it can also be used as a makeshift weapon.

If he encounters an enemy he cannot escape, Yang Yao plans to detonate the liquid hydrogen inside the thrusters, fusing it into helium to create a massive explosion that would be too powerful for ordinary soldiers to withstand.

Of course, detonating hydrogen is not a simple matter. Hydrogen is closely related to atomic bombs and has considerable power, but its technical complexity is much greater than that of atomic bombs. Not to mention that Yang Yao's creation is a miniaturized version, which makes it even more difficult.

Furthermore, hydrogen has a very high ignition point, and without a fission reaction, its power is actually not very great.

Coincidentally, Yang Yao found a piece of fluorinated cerium lanthanum ore on the ground in the suburbs. The trace amount of plutonium-244 found in the fluorinated cerium lanthanum ore is an important additive in the hydrogen bomb fission reaction, which allows hydrogen to be completely fissioned into helium.

Yang Yao couldn't resist. With this amount of plutonium, he could create a small hydrogen bomb, which led to the creation of this small helium conversion device.

Apart from third-generation and above super soldiers, first- and second-generation super soldiers without powerful genes would also be a huge threat from nuclear bombs, enough to kill them!

I'm not going to be human anymore! From today onwards, I'm going to be a nuclear bomb!

It's not as powerful as a high-yield hydrogen bomb; the small amount of liquid hydrogen in the thruster is at most slightly more powerful than an intercontinental ballistic missile.

Another issue is the risk of accidentally injuring yourself; if you get too close, you might end up getting hurt yourself.

However, this thing was originally intended as fuel for armored mines. Yang Yao wouldn't do that unless it was a desperate situation; it was just a powerful trump card.

I checked the time on my notebook and realized it was still early, so I lit the furnace and put some metal I had collected into it to start forging the outer shell of the landmine.

The furnace that Yang Yao made by hand was definitely not as good as a professional blast furnace. The temperature was just enough for Yang Yao to produce weakened steel, which couldn't compare to real steel, but it was definitely much stronger than iron.

As I said before, it's cheap. The coal chunks used for this little fire were ones Yang Yao picked up outside a charcoal stall. Yang Yao continuously fed the extracted acid and oxygen into the furnace. Once the metal had coalesced, he used tongs to remove the metal chunks and placed them on a pre-prepared iron plate.

Taking out a hammer he'd smuggled from the factory, Yang Yao began his grueling iron-lifting journey right there on the iron plate. If even the Starks could handcraft armor, Yang Yao refused to believe he couldn't forge a landmine!

The noise traveled along the walls. Fortunately, it was daytime and Yang Yao had dug the space deep enough, otherwise the noise would have been enough to cause complaints from the residents above!

In the following days, Yang Yao went to work during the day, scavenging for trash at the junkyard while gathering experience, and also spent his spare time designing landmine programs and lifting weights in the basement.

During this time, Yang Yao saw Qi Lin's figure several times on his way home. He also asked the factory manager, who said that Qi Lin was located on Airport Road, just a few streets away from the slaughterhouse.

This immediately made Yang Yao feel insecure. Although they were several streets apart, Yang Yao refused to believe that such a short distance wouldn't be within the attack range of the Taotie soldiers.

If they start fighting, it's not impossible that you might accidentally get caught in the crossfire.

As the saying goes, if you're not 100% sure, even if there's a 99% chance you'll be fine, it's still like courting death!

Yang Yao had already learned his lesson once, and with his luck stat of only four points, he really lacked confidence.

Several days passed, and Yang Yao finally finished crafting the necessary parts for the landmine in the basement. He also successfully extracted a significant amount of hydrogen through water electrolysis and compressed it into liquid hydrogen.

After placing all the parts on the table, Yang Yao began assembling his current life-saving equipment.

First, he added liquid hydrogen to the thruster. Then, Yang Yao quickly assembled the landmine with both hands. Although this was his first time, it was as if he had assembled it tens of thousands of times before.

Control panel, chip, thruster, shell, signal transmitter...

Finally, Yang Yao successfully hand-molded an ugly, somewhat rough-looking oval-shaped landmine.

The front of the landmine doesn't look very appealing; it resembles a distorted flower, but those are actually textures formed by armor plates.

Despite its rough appearance, Yang Yao was still very satisfied. This was the first high-tech landmine he had successfully created. How could he not be proud of it?

Reaching out to trace the texture of the landmine, Yang Yao grabbed the strap beneath it and slung it over his shoulder. At the same time, he slipped a metal bracelet from the table onto his right wrist.

He jumped around to get a feel for the weight; it was about thirty kilograms. However, Yang Yao's physical condition was still quite good, so this amount of weight was acceptable for him.

Now that he had made it, Yang Yao naturally had to test whether it would work. He raised his right wrist...

"out!"

With a whoosh, a bright white plate, propelled by a blue flame, embedded itself into the wall at supersonic speed.

Upon seeing this, Yang Yao couldn't help but burst into laughter. In Yang Yao's eyes now, this was no landmine; it was clearly a sword box!

This mine can achieve such power with just one armor plate. Keep in mind, the landmine I'm carrying on my back has eighty-one pieces of armor.

This gave Yang Yao a better direction for improving the landmine: if the outer side of the armor plates were sharpened, it could potentially be used as a weapon.

"Not bad! It's really dark enough. It wasn't for nothing that I raised you by scavenging garbage!"

Yang Yao took off his landmine backpack and gently patted the surface of the landmine. With this thing, at least ordinary stray bullets shouldn't be able to hurt him!

Pulling out the scales stuck in the wall, the willow-leaf-shaped scales only had a few scratches, were a few centimeters thick, and felt springy to the touch, indicating good shock absorption and reducing potential damage.

After that, all you need to do is polish the edges of the willow leaf armor plates, which should also increase its damage. Pretty good!
