The bee flying knights who have splashed charcoal ash again and again raise their flight altitude and begin to return home, the protagonist leads the team in front, if he doesn't go, the flying knights who follow the action will not leave, and the air action communication is inconvenient, so he can only follow the highest-status commander.

Once they spend a long time outdoors on a still cold and overcast day, the Flying Knights will be in danger if the warm baby fails, so they must rush back to the lair as soon as possible after the mission is completed.

But the protagonist's heart is still on the ice north of [to the West City] at the moment.

The destroyers waiting to cross the river on the north bank as far as the eye could see were gathering more and more, and thousands of them were each divided into several formations.

And yesterday, the surface of the river, where the Divine Envoy King's army worked hard for a day and finally showed signs of thawing, played a role for half the day. Now it freezes again in a cloudy day with weak sunlight, which makes the protagonist anxious.

What else can be done to stop the Destroyer from crossing the river?

The protagonist thinks while flying, and when he is not careful, a mysterious ball in his left middle limb warms the baby and falls.

The other Flying Knights' mystery balls are tied to their bodies with ant silk, so that they do not affect the movement of their limbs. But the protagonist felt that it was more time-consuming to assemble and disassemble the mysterious ball when taking off and landing, so he used his first two limbs to drive Xiaoqing II, and put a mysterious ball on the back of the mount to warm up with his middle limbs, and flew directly.

Just now, the protagonist has been distracted, and he let go of his hand carelessly, and actually dropped a mysterious ball. Fortunately, the other mystery ball is also enough to heat up, and the two mystery balls are meant to be double safe.

The mysterious ball fell flutteringly under the action of air resistance and wind, and the protagonist stared at the mysterious ball while flying, and a flash of inspiration flashed in his mind, and the protagonist quickly grasped this glimmer of inspiration and had an idea.

I'm the dividing line

The team of flying knights landed on the top of the ant mound in the main nest [Qingqiu City], and immediately a worker ant came out in the cold, helped remove the nut shells, assisted the flying knights to come down, and then led the bee mount into the nest.

The protagonist hands Xiaoqing II over to the care of the worker ants, and goes directly to the treasury of [Qingqiu City].

All the way through the passage illuminated by the faint blue light of fluorescent bacteria, the protagonist arrives in a warehouse far from the combustion chamber in the deepest part of [Qingqiu City].

There are hundreds of mystery balls stacked here, all of which are trophies from the previous hillside battle, and a thousand of them were transported here for preservation, most of which are still piled up here.

There are still more than 600 that can still be used as a warm baby, and the other part has been consumed in the operation of the past two days, and the other part has not been recovered from the flying knight who has just returned.

When these mysterious orbs are smashed, they will leak a deep blue liquid, which will oxidize and explode after a while, and the explosion will be quite powerful. That's why these "bombs" are kept in a warehouse far from the combustion chamber.

Since it's a bomb, can't it blow up the ice!! The protagonist suddenly thought of this, and then he had the "New River Opening Plan".

The explosion of the mystery ball is not small, and the protagonist was almost killed at the beginning, so it should be feasible to blow up the thin layer of ice.

And even if the power is not enough, it can still be made up in the same amount, if the more than 600 mysterious balls in the warehouse are detonated together, it is no less powerful than the detonation of several grenades in the human world.

However, how to detonate these mysterious balls is still a problem, the way to smash and detonate is too dangerous, and only the force of the protagonist with a copper hammer is enough to smash it, and the protagonist does not want to risk it.

Thinking of the thermal weapons of the human world, in addition to the impact detonation, there are also ways to detonate with fire, and the protagonist decides to do an experiment.

I'm the dividing line

A nut shell is placed in an open area outside of [Qingqiu City], and the protagonist and Rambo Fei, along with several male ants, are surrounded by guards, hiding behind rocks a little farther away to peek out.

The nut shell was stuffed with hay and dry moss, and a small piece of charcoal with sparks had been sent in by the worker ants with a long wooden shovel, and after igniting the hay and dry moss inside, the worker ants stuffed some charcoal blocks into it, and then transported the nut shell to its destination.

A worker ant takes the ball in its mouth, goes to the opening of the umbilicus of the nut shell, throws the ball into it, and then runs away.

The ants who were watching also quickly retracted their heads, and it was about half a minute before the ants hiding behind the rocks heard a violent explosion.

After the explosion, the protagonist looks at it, only to see a large puff of black smoke rising from the test site, forming a miniature mushroom cloud rising into the sky.

A tennis ball-sized pit was blown out of the ground of the test site, which shows the power of the explosion of the mystery ball. The white nut shell, which was originally solid and copper-like jaws that could not be bitten, had long since been torn apart, and only a few fragments could be seen on the ground.

At this time, not far away, some insects that had woken up but were still avoiding the spring cold were arching out of the ground in fright, desperately fleeing into the distance, and they couldn't care about the spring cold.

The protagonist is satisfied that the Mystery Ball can indeed be ignited by fire, and that there is enough time for the ignited ants to escape.

But is a single mystery ball enough to blast the ice? If repeated detonation is required, it may be dangerous for the ice to loosen at that time.

And the umbilicus of the nut shell is stuffed with four or five mysterious balls at most, and one more is too late to escape, and the other is to reduce the fuel in it and shorten the burning time, which may not be enough to wait for the flying knight to transport it to its destination.

The protagonist decides to stuff three mystery balls in a nut shell first, and if it is not enough for the next action, the equivalent will be added.

At this time, the protagonist asks the worker ants to prepare for a second experiment, this time with a mysterious ball that has been used and no longer heats. These mystery balls have lost their use as "warm babies", and the protagonist wants to see if they can be reused, and if these waste mystery balls can also explode, there is no need to waste good mystery balls.

But after three or four minutes, the waste mystery ball thrown into the burning nut shell did not explode, and it seemed that it had completely lost its internal energy.

The protagonist does not give up, and personally smashes a waste mystery ball with a copper hammer, and then hides quickly.

But again, several minutes passed, and no explosion was heard. The protagonist looks over and sees a faint blue liquid coming out of the Waste Mystery Ball, but there is no oxidation reaction. The liquid is much lighter than the pale blue liquid that the protagonist has seen before that explodes intact orb, but is similar to the glow of fluorescent bacteria.

It seems that the waste mystery ball is not an explosive. The protagonist is not discouraged, it was just a whim.

He sent the worker ants to clean up the experimental site, and then hurriedly prepared to implement the "New River Opening Plan". The weather is getting cooler, and a new wave of cold air may be coming again, and the "New River Opening Plan" is urgent!
