Once assembled, the protagonist can't wait to experiment with the power of the ballista.

Since the research team did not manufacture and transport any ballista ammunition, the protagonist had to find a way to solve it on his own in [Swamp City].

However, this is not difficult, and the ammunition used for ballistas is usually stone bullets or arrows.

Stone bullet is the simplest, just find a suitable size of stone that can be put into the bullet groove in the main beam, of course, in order to ensure that the trajectory is straight, the stone is best processed into a spherical shape.

The arrows used in ballistas are usually specially made giant arrows, and the trajectory of the arrows is the most accurate, and there will even be cases where the next arrow hits the first arrow.

Before the Tanyuan Alliance, the Song army used the bed crossbow to kill the commander of the Liao army in one fell swoop from a long distance, and its accuracy can be seen (there are also opinions that it was lucky to hit by mistake).

The protagonist first experiments with the power of stone bullets, and the island where [Swamp City] is located lacks almost everything, but only small stones are not scarce, and on the windward side of the island, there is a small beach that has been carried by the wind and the current, and there are both small gravel and large pebbles, and a large number of stones of all kinds are piled up there, and it is not difficult to find the right size stone bullets.

In the past, when a large amount of slings were consumed in battle, the ants would come here to replenish the stones, and the ant silk was tied to a new sling. Ballistae require a larger stone projectile than a stonethrow, and the two do not affect each other.

The ants quickly find dozens of stone bullets for the protagonist, the protagonist first pulls the string of the ballista, hangs it on the trigger, and then puts the stone bullet into the trough, and then lands on the ground with the main beam of the ballista in the middle limbs, aiming at the trunk of a shrub not far away.

Then, the protagonist's front limbs pull out the trigger forcefully, and the ballista is violently ejected by the full spring to drive the bowstring, and it is stretched back into a straight line, and the protagonist only hears a terrible wind howl, and the stone bullet has turned into an afterimage and disappeared from the bullet groove.

The bush grain does not move... A small splash exploded on the water in the distance... Apparently, the stone projectile did not hit the bush that the protagonist had been aiming at earlier, but instead passed by and fell into the water.

The protagonist pondered for a moment, it should be because the trigger was too tight, and when he pulled out the trigger, he used a little too much force, shaking the main beam of the ballista.

He pondered for a moment, then tried to pull the trigger repeatedly. Finally, he asked the ants to fetch a piece of insect grease and apply it evenly to the surface of the trigger, reducing friction.

This time, pulling out the trigger is less strenuous, and the protagonist in an ordinary state can easily do it.

However, the process of pulling out the trigger will inevitably shake the ballista slightly, and no matter what you do, it is difficult to avoid this interference. After all, the structure of this ballista is too simple, and the protagonist is not a sniper, so I don't know that the action of "pulling" the trigger in this case should be done as unconsciously as possible in a natural situation, that is, "consciously aiming, unconsciously firing".

In addition, the grooves on the main beam of the ballista are not straight enough, and the protagonist experiments several times and finds that it is difficult for him to accurately hit the target at half a meter away, and can only do it within half a meter.

Fortunately, the ballista is quite powerful, and when a single stone projectile is fired into the trunk of a bush, it will sink deep into the trunk, and the power can be seen - at least enough to break through the carapace of the parasitic beasts.

Although the accuracy is insufficient, the protagonist is not discouraged, as the first ballista, it is experimental in nature, and it is already good to be able to do this step.

The protagonist simply takes a different path, he tries to fire multiple stone bullets at once, and after repeated experiments, when firing five or less stone bullets at a time, the power is enough. Multiple stone projectiles spontaneously form a barrage, which is more effective when shooting at targets moving at high speeds. At the very least, this ballista can be used as a qualified anti-aircraft weapon, making up for the embarrassing loophole that the anti-aircraft firepower of the Divine Envoy King's legion is basically zero.

Later, the protagonist wants to experiment with firing arrows, which theoretically have a longer range and higher accuracy than stone bullets.

Since the arrows were not made beforehand, the protagonist initially replaced them with the riding spears of the Flying Knights. These lances are made of the tough wood fibers of plants, and the top is fixed with ant silk and ant glue to the stone or ceramic head, which is very tough in battle, which is convenient for flying knights to swing and stab, and once stabbed, the gun shaft will break, leaving the gun head in the enemy's body difficult to pull out.

However, when firing this kind of cavalry gun with a ballista, due to the lack of strength of the barrel, it will be directly swept off by the bowstring and smashed, and it cannot be successfully shot.

The protagonist experiments with the right-sized twigs dropped by the bushes collected on the island, and this time it was successfully launched, with a considerable range, but because the branches are not straight enough, and there are no arrows and arrow feathers, the accuracy is not ideal.

After the experiment, the protagonist is still worried about the ballista ammunition, and a large number of ants stop what they are doing, either busy collecting stones on the beach, collecting suitable branches on the bushes, or processing ammunition in the nest.

Shrub branches are stripped of bark by ants, uneven parts are cut off, arrows are sharpened with jawknives or other tools, and feathers made of wounded insect leather are attached to the tail of the arrow.

The ants are slow to process arrows, making two in one night, but as long as there are stone bullets, ballistas can fight.

Now, the protagonist is looking forward to killing the parasites with ballistas the next day, and his desire for the appearance of the enemy has never been more urgent.

From the second half of the night, the fog in the sky increased significantly, and by early morning it was already full of dark clouds, and the sun could not be seen rising in the east.

When the time for the parasitic ants and parasitic war beasts to appear, the enemy did not appear, but began to rain lightly - this was the first rain after the beginning of autumn.

As the saying goes, an autumn rain is cool, and the rain is still falling, and the swampy area can already feel a noticeable coolness that is different from the summer heat.

The ants' instinct has foretold this rain, and this rain will become heavier and will continue for a while.

No insect likes to go outside when it's raining, it's extremely dangerous and can easily drown, and parasitic insects are obviously no exception.

After realizing that the enemy will not appear today, the protagonist is actually slightly disappointed. But soon, he was about to devote himself to a new job, and he didn't have time to think about it.

[Swamp City] hasn't experienced rain before, and the protagonist asks the ants to step up their inspection of the nuclear cleaning drains.

There were also the two ballistae that were placed outdoors, which were so large that they could only be transported back indoors from the Flying Knight Passage. But now it's too late, so I have to move to a higher ground under the bush to shelter from the rain, and then cover a few pieces of insect leather to protect from the rain.

After everything is done, the raindrops start to become bean-sized, as if to herald the arrival of autumn.
