However, this method is very labor-intensive, and cutting down those Protoplastae doesn't actually serve any practical purpose.

It would be better to put wild boars on it and let them eat more algae so they can grow some meat.

Furthermore, wild boars have a very sensitive nose; they will swim directly to eat some *Prosopa spp.* that are not too far away.

There's no need to worry about oxygen deficiency now, as the proportion of oxygen-releasing plants is many times higher than that of Protoporphyra.

There are a large number of aquatic plants in the waters near the Protoscolecula, which continuously supply oxygen to the surrounding area every day.

Aside from feeling a little frustrated at first, this feeling will quickly disappear once you cut off the adult Protoporphyra that release carbon dioxide.

Wild boars aren't stupid; when they come to hills that haven't been cleared by us, they don't go straight to the innermost part.

They typically feed on newly sprouted protozoan algae on the outer edges. After a long period of cooperation between wild boars and humans, whenever a human boat passes near this area, the wild boars will howl loudly.

The loud noise will attract our attention. At that point, we can simply dock the large ship nearby, and everyone can go up and cut down the adult Protoplastia. The rest can be left to the wild boars to handle with their mouths.

As long as these wild boars are around, no *Prorocentrum spp.* can grow to adulthood.

In the past year or so, Prosocephalotaxus sinensis has almost disappeared from the area we have explored, and we have to say that we have benefited from this misfortune.

However, the water is still very dangerous, but it's better on the ark. Those aquatic behemoths can't yet climb from the water onto the ark's deck, which is tens of meters high.

However, large cargo ships are different; these ships are generally only a dozen meters high. This is fine on the water, but when they are near mountains that jut out of the water, our ship's height is not such an advantage.

We once encountered the same amphibious monster that attacked me back home. It sneaked onto the deck and hid when we were near the mountain peak.

At first, we were only concerned with the movement on the water's surface, and no one would have imagined that such a deadly animal was hiding on their deck.

They are not only powerful in the water, but also formidable on land. These creatures seem to have a natural inclination to ambush their prey.

They hide in the shadows of the deck, and when our people are not paying attention, they will use their tough, sinewy tongues to stretch out and tightly wrap around the neck of their opponent.

Once its sharp tongue, like that of a python, is entangled, there is no way to shout out; one can only be dragged off the deck and eaten.

Later, a member of the tribe discovered some bloodstains and slime left on the deck, and realized that the mysteriously missing tribesmen had been dragged away by something.

So far, we've tried many methods to deal with them, but the results haven't been very ideal. They're as wary as wolves; they won't easily approach unfamiliar things.

Therefore, the traps we set up by the water were completely ignored by those guys.

When traps failed, we devised a method of luring. To lower their guard, we placed the bait far from our ships.

Since I didn't need to consider using them for food, I specifically harvested some of the aconite grown on the Ark and concentrated it to extract aconitine powder with extremely high purity.

This stuff isn't the same liquid I made by boiling aconite directly. This highly pure aconitine is a very deadly and dangerous poison.

Even if it comes into contact with the skin by chance, it can quickly lead to poisoning due to the absorption of trace amounts through the skin.

Therefore, when handling this stuff, you must wear protective gloves and use objects such as sticks or spoons to come into contact with these highly toxic powders.

I'm not worried that those guys will notice anything unusual. The purified aconitine has no smell at all, so it's impossible for them to detect anything wrong by smell.

The only thing that can sense the abnormality is the tongue; this stuff is extremely bitter, and you can immediately tell just by tasting a little bit.

Unfortunately, even the most cautious sea monster is helpless against it. Whether they ingest it or merely lick it out of caution, it's enough to kill them several times over.

This stuff used to be used in the black market as a highly effective poison, specifically for illegal and disorderly activities.

Our baiting efforts paid off quickly; those creatures were indeed cautious. They didn't eat the poisoned bait directly, but instead chose to lick it lightly first.

Perhaps in their minds, even if something is poisonous, a light lick might cause dizziness and nausea, but wouldn't lead to death.

But they are still animals after all, and their thinking is too naive. This stuff is poisonous to dogs; even before it reaches their stomachs, they will die within seconds from organ failure.

It is many times more toxic than the three-step poison used to kill dogs, so people who use this method to poison dogs are usually not doing so to eat them, but mostly to take revenge on their owners.

If anyone dares to cook and eat these poisonous dogs, as many as they want, I guarantee they won't see the sun rise tomorrow.

In the end, we counted that the poison bait had killed more than 20 giant water monsters, each weighing over 500 or 600 pounds, in one go.

We originally thought that kind of water monster was a rare existence, but we didn't expect that there are actually quite a few of these things.

After that, we learned our lesson. Once we reached the shore, we would leave people on the boat to guard it. All their crossbow bolts were poisoned with aconitine; if you shot one in the eye, it would be instantly dead.

With the significant reduction in the number of Protozoa, our lives have become relatively leisurely, and people spend more time entertaining themselves.

Occasionally, one might see a few dying Prosocephalotaxus sinensis during the voyage, but they usually only appear briefly before disappearing.

Currently, the water and mountains have become clearly distinct; the water is still water, but the mountains are completely bare, without a single hair to be seen.

After several months, we found that the previously disappeared Protoplastia did not reappear.

I started trying to sow some grass seeds and tree seeds on these lands.

The situation is not bad; at least the land where plants have grown no longer shows any trace of Prosopa spp.

The land is somewhat barren, and the plants can only survive by relying on gaseous fertilizers and not very strong sunlight.

Plants are much better able to adapt to poor soil than Protoporphyra, which relies on directly absorbing nutrients from the soil.

These plants are not as lush and green as they used to be; they only need one generation to replace them.

Those withered branches and leaves will become nutrients again, allowing this barren land to slowly regain its vitality.
