Zhang Fan also noticed the pollen in the sky, which was useless to the Zerg.
But for the insects in the forest, this is a powder that goes crazy.
After scattering all the pollen, the mosquitoes began to circle into the sky and gradually disappeared from Zhang Fan's sight.
The giant insects that had calmed down once again rioted and launched an even more violent attack on the springtails.
Zhang Fan once again mobilized the self-exploding mosquitoes, aimed at the insect army and began to sprint.
Who said that self-exploding mosquitoes can only fight in the sky?
This is not a game.
"boom" There was another thunder on the ground, limbs flew all over the sky, and blood rained from the sky.
The bloody rain soon stopped, and the mosquito kings in the distance were stunned, wondering how they had caused such a ferocious attack.
In fact, this was Zhang Fan's idea, and Adam put it into action.
The key to action lies in gunpowder.
As we all know, black powder is generally produced from saltpeter, sulfur and charcoal.
Charcoal is so easy to find.
Didn't you see that the forest was burned by the fire and it hasn't recovered yet?
The charcoal contained in it is considered inexhaustible for Zhang Fan.
The problem of sulfur is also easy to solve.
How could there be no crater in such a large area of land, and the sulfur is produced near the volcano.
The most difficult thing to deal with was saltpeter.
When Zhang Fan was considering saltpeter, he also thought about using other substitutes.
Because saltpeter in nature is often formed by decomposing and oxidizing nitrogen-containing organic matter in the soil into nitric acid under the action of bacteria and then combining with potassium in the soil, it is commonly known as potassium nitrate.
Zhang Fan only knew that it was saltpeter, but he did not know that it was potassium nitrate.
It was also by chance that he discovered insect excrement near the forest, so he thought of those awesome guys in historical fictional novels who made guns and ammunition.
Didn't they all start by digging out excrement?
He took back the collected feces and conducted simulated experiments in the evolution chamber.
At this time, the second forest attack had just broken out.
Don't think that gunpowder cannot exist in this period.
Zhang Fan is not a fool.
Why not take advantage of such a good thing?
To put it bluntly, saltpeter is potassium nitrate.
The potassium element is the same as the sodium element.
It is not surprising that it is everywhere.
The acquisition of nitric acid requires biological excretion.
As we all know, living things are rich in protein, and the most important element in protein is nitrogen.
Oxygen is required for biological activities and also oxidizes proteins, producing nitric oxide in the body.
This nitric oxide poses no threat.
When nitric oxide comes into contact with air, it oxidizes over time to form nitrogen dioxide, and when it comes in contact with water, it turns into nitric acid.
Nitric acid reacts with potassium in the soil to form salt, so the extraction of saltpeter is not difficult for Zhang Fan.
Now that saltpeter, charcoal, and sulfur are available, the next step is to ignite the fire.
This kind of ignition cannot rely on the friction of insect eggs to produce flames like projectiles.
The flames produced are very short and can only cause very little damage.
Self-exploding mosquitoes must be able to explode.
Explosion is the real art.
It must explode from the inside out.
The bodies of self-exploding mosquitoes after birth contain a large amount of black powder, which Adam discovered through practice.
Regarding the issue of ignition, Zhang Fan considered many aspects, but he was still unable to satisfy everyone's expectations.

The best thing to use was flint and steel.
However, flint and steel can only produce flames through collision.
When dealing with enemies, it is impossible to collide with each other and then trigger gunpowder.
In this way, the enemies will have run away.
A simpler method must be thought of.
Under such circumstances, Zhang Fan thought of white phosphorus and some of the white phosphorus experiments his teacher had done when he was a child.
The chemical properties of white phosphorus are very active allotropes and it is a substance that is prone to spontaneous combustion.
Its ignition point is 40 degrees.
The ignition point is very low, but it is enough to ignite gunpowder.
Zhang Fan still uses the old method of igniting white phosphorus through a high-temperature reaction of sodium and water.
This can start igniting while flying and explode when it reaches the target.
Although the explosion effect of a self-exploding mosquito is not strong, a large number of them will produce a huge effect.
This is a process of transforming quantitative changes into qualitative changes.
Another thing to mention is that the self-exploding mosquito itself has a very short life, only lasting a few hours, and its body is as brittle as paper, so when fighting the enemy, try not to let the enemy attack, so as to avoid causing a lot of losses.
Emperor Mosquito Jing was stunned.
It was the first time he saw an explosion appearing out of thin air.
He couldn't figure out how it was created.
No, we can't let the enemy continue to be so arrogant.
Emperor Mosquito Jing's body gradually began to glow with golden light.
The Chironomid King and the Giant Mosquito King flew out at this time to say that they would meet this group of hateful Zerg.
One has high magic resistance and the other has high physical resistance.
They should be able to deal with them together.
Emperor Jingjing was still a little worried about this, so he sent the Anopheles King out as well, reminding it to act with caution and to retreat as soon as something unexpected happened.
The three mosquito kings all moved out together.
This was the last strength of Emperor Mosquito Jing's men.
Don't even think about sending the big mosquito king out.
This big guy is already shivering on the side.
If it weren't for the mosquito king who protected him, he would have been torn into pieces by the other mosquito kings.
The explosion of self-exploding mosquitoes produced excellent results, so the third batch of self-exploding mosquitoes was produced in full swing.
Bad news came from Adam.
All resources were in short supply.
If they could not defeat the opponent immediately, they would have to retreat.
Zhang Fan received Adam's information and fell into deep thought.
Currently, he could only produce four batches of self-destructing mosquitoes, and the last two must be used on the blade.
The poisonous baneling insects could hold on for a while longer, so Zhang Fan prepared an induced retreat to lure these big bugs into the poisonous explosion minefield.
The Zerg began to take action, and the Hydralisk moved its body and began to retreat backwards, at a very slow pace, turning back and shooting at the insect army step by step.
The worker bees were also diligently digging holes in the back, placing poisonous banelings in the holes and covering them with soil.
Just when the Hydralisks began to retreat, Zhang Fan discovered that the mosquito tribe began to attack again, this time it was the three mosquito kings.
Zhang Fan will dispatch the flying dragons again.
From a numerical point of view, the flying dragons are at a disadvantage.
Each chironomid is carrying the larvae of a giant mosquito.
They imitate projectiles and throw the giant mosquito larvae out in unison.
The larva in mid-air opened its mouth and bit towards the flying dragon at an extremely fast speed.
Zhang Fan couldn't let them succeed easily, so he controlled the flying dragon to fly upward.
However, during the flight, we were attacked by Anopheles mosquitoes again.

The attack power of these Anopheles mosquitoes is not strong, but the toxins in their bodies are strong.
