Because he didn't expect it to be a consumable, the protagonist brought a big mystery ball from [Bridgehead] to [Waterfront City] at that time, and now this mystery ball is out of energy, and it is useless to continue the experiment.

The protagonist had to wait for another two days, and when the temperature rose up, and the daytime sunshine was good, and when it was a day suitable for the paver ants to go out, the protagonist sent a team of paver ants to go to [bridgehead], while learning about the battle situation over there, and bringing back some of the big mystery balls for experiments.

In early winter, even the paving ants did not dare to set out early in the morning, and they waited until about noon, when the sun was at its strongest, to go outside the nest. Then bask in the sun for a long time on a rocky without snow to replenish the heat before setting off.

[Waterfront City] is not far from [Bridgehead], but it still took a lot of time for the paver ants to turn back.

Because there is still snow on the ground, in order to maintain body temperature and prevent the snow from sticking to their bodies and melting and taking away valuable heat, paving ants must choose a dry road surface without snow to keep their bodies dry at all times, rather than walking along the fast ant path.

If you can't get around the snow when you are moving forward, look for leaf fragments, dry grass stalks, mud, etc. to cover the road before walking. There is only a rope bridge that must be passed, and there is no way to detour, but must be passed.

Fortunately, there was no snow on the rope bridge, which was constantly swinging in the wind, throwing the snow into the surface of the large river, which was already completely frozen. The rope was a little wet, but it didn't affect much.

The paving ants crossed the rope bridge and came to the [bridgehead]. Although the big-headed ants here don't like paver ants, they have a smell similar to that of the same family, and the protagonist has also issued a death order to ensure the freedom of the paver ant team in winter.

The male ant commander of the big-headed ant squad who was in charge of guarding the gate personally escorted the paving ant squad to Rambery to avoid any trouble.

Ramboree is currently the highest-ranking male ant in [Bridgehead], and the de facto commander. He told the Paving Ant to tell the Great Messenger King that [the bridgehead] had not been attacked by the Destroyer. Then, he hurriedly asked these unpleasant destroyers to carry the big mystery ball and get out.

A team of fifty paving ants brought back twenty-five large mystery balls, and in the afternoon they had returned to [Linshui City], and there were mystery balls on the way back to keep warm, which was easier to walk.

The protagonist knows that [Bridgehead] has not encountered a battle, and although he is puzzled, this is not necessarily a bad thing.

Later, he returned to experimentation.

These big mysterious balls in front of me have begun to heat up on the road, and it has been an hour.

Then the protagonist left five large mystery balls outdoors, and let the two paver ants hide with the mystery balls at the leeward root of the big banyan tree to continue the experiment, and the rest of the big mystery balls are stored in a warm place underground, and they do not need to consume energy to heat up for the time being.

The paver ants experimenting outdoors are surrounded by mysterious balls, and they can only work at night to ensure that there are ants on duty at all times.

The next day, the mystery ball was still hot, and the two paving ants who had stayed up all night outdoors were also alive and well under the shelter of the warm mystery ball. Thanks to the fact that there are no strong winds and no new snowfall tonight, otherwise it may not be enough to rely on the mystery ball to keep warm.

In the end, in the single-digit temperature outside during the day and the severe cold at night below zero, the five mystery balls basically maintained a fever time of less than two days.

The protagonist estimates accordingly:

At a single-digit and constant room temperature, the Mystery Ball can maintain its heat for approximately 72 hours.

With outdoor temperatures close to freezing and dropping below freezing at night, the Mystery Ball can last less than two days, or less than 48 hours.

If the temperature drops further, the duration of the Mystery Ball is expected to be shortened.

In addition, according to the experiment, the "key" that triggers the heating of the Mystic Ball is also the temperature, and the Mystic Ball heats up in the tree hole area of [Waterfront City], but stops heating in a relatively warm burrow.

Therefore, the necessary temperature critical point for the Mystic Ball to heat up is about 0 degrees Celsius or more, and at a temperature below 20 degrees Celsius, the maximum possibility is about 10 degrees Celsius.

After the heating time and trigger temperature of the mystery ball are roughly determined, the protagonist has also determined that this thing can indeed be used as a warm baby.

After experiments, even the big-headed ant warriors, who were originally not suitable for winter outings, were able to move outdoors by tying the mystery ball to their backs.

It's just that big-headed ants are still not as hardy as paver ants, even in good weather without wind and snow and sunny days, big-headed ants carrying mysterious balls will still fall into hypothermia once they are active for more than half a day.

And the paving ant warriors, who are originally resistant to the cold, can even move for up to three hours in places where the sun cannot shine directly after carrying the mysterious ball "Warm Baby", which is a winter paver ant that they have not been able to do before, and they have always only dared to move under the sun.

I'm the dividing line

The Mystic Ball explodes, generating steady heat, and apparently contains a lot of energy inside.

This reminds the protagonist of batteries, which are also liquids (electrolytes) inside and can generate heat, and some batteries will also explode.

If the Mystic Orb resembles a battery, then what role does this play in the Destroyer's body?

The corpse of The Destroyer has been seen many times by the protagonist and still retains its biological form. Why is there a "battery" in an organism? Could it be that The Destroyer is really a cyborg?

In this ant world, what kind of civilization has advanced enough to make biochemical creatures? Is there any connection to the stone in the shape of a human skull that the protagonist sees in the swampy area? Could it be that the protagonist's conjecture when he first crossed over was correct, and humans still live in this world where there are no large creatures?

The mystery in the protagonist's mind is not solved as more and more clues are discovered, but rather like a ball of thread that is entangled, and the more clues there are, the messier it becomes.

He remembered that the large and small orbs were connected by black threads in The Destroyer's body.

If the big mystery ball is the battery and the chitin black thread is the wire, what is the little mystery ball in the Destroyer's head?

Unfortunately, once the little mystery ball leaves the destroyer's head, it quickly turns gray and gray, and the protagonist can't experiment with the little mystery ball.

In addition, if the mystery ball is a battery, how is it charged? If it is not recharged, it is clear that its energy will not be able to support operation for a long time?

Is it solar? The protagonist tries to place the orb in the sun, but the ball that has lost its energy is not recharged.
