After this mysterious ball was brought over by the protagonist from [Bridgehead], he studied it for a while while in his spare time, but he didn't gain much.

A mysterious ball the size of a grain of millet, if it is thrown next to the ant road in the wild, the ants will not look at it, but just treat it as a black gravel, which shows how inconspicuous it is.

But this thing was dug up from the Destroyer's body, and in addition to the large mystery ball, there was also a small mystery ball that would soon decay and change color in the Destroyer's body, and the function of the two was unknown.

The protagonist never knows what kind of creature can dig up such a strange thing, and if it's a stone, it's a bit exaggerated to dig up a volleyball-sized stone in a human body for an ant.

What's even more amazing is that there is a dark blue liquid inside the big mystery ball, once the hard shell of the mystery ball is broken, these dark blue liquid flows out, and it will soon spontaneously ignite in the air, and even cause an explosion.

There are many substances that can spontaneously ignite in the air, such as white phosphorus and sodium, and it is not surprising that the confined space burns violently and explodes. But the protagonist's poor knowledge of chemistry makes him unable to think of any dark blue liquid with this property.

The protagonist can't figure out the composition of this dark blue liquid, and when he sees the liquid, he just looks in a trance, and suddenly he is awakened by the warning omen in his heart, and he quickly escapes.

It's just that this explosion caused heavy losses to the protagonist's Praetorian Guard team, and the soldier ant guard "Mulan", who accompanied him almost day and night, also died in this accident.

With such an experience, the protagonist naturally does not dare to destroy the shell of the mysterious ball to study its internal structure. But such a mysterious thing, and closely related to the Destroyer, the greatest enemy of the Divine Envoy King Legion, the protagonist still does not stop to study it.

Unable to do internal research, the protagonist can only start with the appearance and measurable parts. Before moving into the cave [in Waterfront City], his research report was as follows:

Subject: Mystery Ball.

Object Source: Excavated from the inside of The Destroyer's abdomen.

Primitive form: In the middle of the Destroyer's abdomen, near the carapace on the back, adjacent to other organs such as the digestive tract and excretory tract, there are black chitin wires connected to the small mystical bulb of the brain, and there is no visible connection to the rest of the Destroyer's cells.

Appearance: Black chitin shell, the same color as the Destroyer's carapace.

Dimensions: The whole is egg-shaped, or similar to the egg type, with a diameter of about 0.5 mm at the longest end and a diameter of about 0.3 mm at the shortest end.

Density study: After experiments, the large mystery ball can sink into water, and the overall density is greater than that of water, that is, greater than 1 gram/cubic centimeter.

Using simple tools, including a ceramic scale, with the help of water, a number of materials comparable to the volume of the large mystical ball were selected, and then compared on a balance made of simple wood and rope, it was found that its density was greater than chitin, and smaller than quartz gravel and copper lamp.

Considering that the large mystical sphere has a dark blue liquid inside, the surface is a chitin carapace. If it is assumed that no other matter or structure exists inside the Great Mystic Sphere, the density of the blue liquid should be greater than that of water.

Stability Studies: Previous experience has shown that the chitin shell is prone to rupture when hit hard, causing spontaneous combustion and explosion of the dark blue liquid inside.

Recently, after the study of safety protection measures, the temperature of the large mystery ball will also rise when it is close to the heat source, and there is a possibility of explosion, so the experiment was suspended.

The above is the protagonist's previous research results.,It's very simple.,Except for some results in the stability and density of the big mystery ball.,Basically I don't know anything about this thing.。

The protagonist even maliciously thinks that in the future in the battle against the Destroyer, these captured "useless" mystery balls can be used as bombs.

It's a very relieving and enjoyable scene to think of the Destroyer cluster being blasted into the sky with a preset "duang" of mysterious ball bombs from the bodies of their fallen companions.

Anyway, this kind of mystery ball is stable in nature, but it can explode when hit hard and heated, which is very similar to gunpowder, and the protagonist has a large number of human methods of detonating gunpowder in his mind to learn from, and it should not be difficult to design and manufacture a simple detonator to detonate the mystery ball.

The simplest is to send a small team of ants carrying small torches of pine resin to burn the shell of the mysterious ball on the spot to detonate it. It's just that these ants responsible for detonation are also dead, and there is a sense of "kamikaze".

The protagonist is naturally reluctant to sacrifice his subordinates, but the ants themselves don't care about the price paid for victory, and the protagonist's remaining human sympathy is forgotten, which is the simplest, and in a sense, the most economical and efficient way to detonate, even the disabled and the old and frail ants can do it.

I'm the dividing line

When moving into the hole, the protagonist is in a hurry and doesn't bring the only mystery ball with him. Today he plans to move out.

But as soon as he picks up the mystery ball, the protagonist feels a warmth coming from the mystery ball.

The protagonist is stunned for a moment, hugs the mystery ball tighter, and then strokes it with his antennae, and finally confirms that the mystery ball is indeed heating up.

At this point, according to the protagonist's feelings, the indoor temperature in the storage room is in the single digits, and the temperature emitted on the mystery ball is comfortable, making the protagonist feel warm, about 30 degrees or more. If it is lower than 30 degrees, then the protagonist will feel cool when he holds it, and if the temperature is too high, he will feel hot.

Before today, when the protagonist was researching the Mystery Ball, it didn't heat up.

What were the differences between then and now? Is it this different condition that triggers the heating mechanism of the Mystic Ball?

The protagonist analyzes it from a scientific point of view, and the biggest difference should be the change in room temperature. Before, the room temperature was about a dozen degrees Celsius, but now it's just over zero.

In order to verify that the temperature change is the cause of the Mystery Ball's heat, the protagonist takes the Mystery Ball away and conducts another experiment.

When the orb is brought back to the warm underground, which is about 20 degrees Celsius, the orb stops heating up within about ten minutes, and its temperature gradually decreases to the level of the surrounding room temperature.

When the protagonist drops the Mystery Ball at the outermost point near freezing in the tree cavity area, the Mystery Ball soon starts to heat up, but no matter how the cold environment changes, it remains at a constant temperature of about 30 degrees.

After repeated experiments in different temperatures of the nest, the protagonist roughly determined that the mysterious ball began to heat up when the room temperature was lower than 10 degrees, and stopped heating when it was higher than 20 degrees, and was able to keep its temperature constant.

This mystery ball is good, it seems that it can not only be used as a bomb, but also as a warm baby. The protagonist suddenly discovers a new use for the Mystery Ball.
