After visiting the farm, Roland came to the rubber bug laboratory.

The room, which was only about thirty square meters, was like an ancient wizard's alchemy room—there was a row of plastic buckets filled with slime on the wall, and the milky white glue that had solidified was stuck everywhere. A cauldron full of burnt gum was emitting a foul smell, and God knows what they had put into it.

The long-handled spoon, bucket and stirring stick used in the experiment only exacerbated this feeling, and when combined with a few toads and bats, it was a perfect restoration.

"Your Majesty," said Kemo Strill with a simple nod of his salute, "I think I've found what you're looking for." ”

Roland noticed his pale face and the gauze wrapped around his fingers, "Are you hurt?"

"A little problem, nothing matters," he waved his hand, then handed over a glass of light red slime, "Your Majesty, please see." ”

Kemo turned the cup upside down, but the liquid did not spill, but slowly squirmed along the wall of the cup, forming a soft hemisphere at the mouth of the cup.

Roland's eyes lit up, and he reached out to catch the jelly-like substance, but was stopped by the chief alchemist.

"No, Your Majesty!" he retracted his cup, "this thing is corrosive. ”

"I remember that rubber bug mucus was supposed to be non-toxic and harmless," Roland raised an eyebrow. Otherwise, it wouldn't be used to make food bags and straws.

"But after mixing the blood, it did change its nature. ”

"Blood?" Roland was slightly stunned, and couldn't help but look at his fingers, "Could it be that the wound on your hand is for experimentation......"

"Of course not, it was just an accident," Kemo stroked his beard and laughed, "no matter how crazy I am, I won't experiment with myself - chemistry is so long, I wish I could go further." ”

After listening to the other party's explanation, Roland finally understood the discovery process of the new colloid.

The coagulability of the rubber worm mucus comes from the mixing of glandular secretions, and according to the difference in the proportion of the two, biorubber of different hardness can be formed, but they are not mobile and cannot be changed once consolidated.

At the beginning, according to the experience of chemical experiments, Kemo added various elemental elements or acids and alkalis in groups, but the final result could not be reversed.

After that, the selection of materials was further relaxed, from complex inorganic salts to organic matter, which were thrown in to observe the effect. Although a number of interesting special gels were discovered during the process, it was never possible to get the new gel Roland wanted.

Until an accident happens.

When he was cutting the waste strip, he accidentally cut his finger, and the blood dripping out contaminated a cup of experimental sample that was about to be consolidated. A large amount of white gas suddenly came out of the cup, dissolving the bird's snout mushroom into a puddle of yellow water.

The solution also became a semi-condensate gelatin.

"The most important feature of the mixture is that it retains the properties of the mixed material. Kemo threw the gel into the furnace, and it glowed brightly, and the flames rose several feet high, instead of slowly blackening like the rubber blocks before and finally turning into a puddle of powder. "I've only added a spoonful of grease to it, and burning it alone may not have achieved this effect, so to speak, it's even better than what you ask for!"

Although the old alchemist's voice looked a little tired, his tone was full of excitement. Looking at the exuberant light of the fire, it was as if a flame was burning in Kaimo's eyes—he had clearly imagined in his mind what it would be like when the gel would be used in large quantities.

Napalm is what Roland is trying to make.

Originally made from gasoline and special thickeners, it is not only much safer to use than liquid fuels with very low flash points, flammable and explosive, and difficult to adhere. Combined with the ignition of explosives, it can instantly create a large burning area, which is difficult to get rid of once it is stained, and at the same time, the raging fire will accelerate the consumption of oxygen, making people suffocate to death.

When he saw that the rubber bug slime had similar coagulating properties, he had an idea for this - if the slime could be completely fused with the ignition and made to burn sufficiently, a simple and crude weapon could be obtained.

After all, the red mist is afraid of fire.

In the Tachira era, the biggest headache for the Federation was the outposts that had already been built. The small area of red mist left the Holy Blessed Army with no choice but to rely on witches with the ability to isolate or clear them to lead them slowly, and the task of dismantling the Mist Tower fell to the mortal army. Often after a battle, the Holy Blessing Army will pay a great price because it cannot be flexible and mobile, and mortals will never return.

It is in this cruel exchange that the devil can weaken the power of the federation every time he establishes an outpost, until the latter is no longer able to stop the other party's actions, and is finally dragged alive by the devils who are surging from all directions.

If they have the ability to set fires, the threat of enemy outposts will be greatly reduced, and the red mist that the devil relies on will become a noose around their necks.

It was probably because of the deep impression of the defeat that Pasha and the others were so interested in rubber bugs - especially Elf, who at first had a lot of complaints about raising bugs of unknown origin in the Third Frontier City, and since Roland stated the idea of a solid-fuel weapon, her attitude has changed a hundred and eighty degrees, and even the tone of the insect has changed.

Roland didn't have to fight the devil at close range now, and he would never let the First Army out of the range of artillery cover until all the moving targets were gone. Therefore, incendiary bombs are more of an auxiliary offensive means, which is a product of the idea of "eggs are not put in one basket", and if there is one, it will not affect the entire strategic plan, and if there is one, it can save a part of the gunpowder and reduce the production pressure of the chemical plant.

On this premise, it would be nice for Kemo Stoll to make a discovery, but the question is ......

"Blood is not an easy ingredient to obtain. ”

"Rest assured, Your Majesty," replied the alchemist, "it doesn't have to be human blood...... The blood of cows, sheep and other livestock can also change its properties, and I have tested this. The only prerequisite is that it has just been released. ”

This reassured Roland a lot, but the second question followed, "Why blood?"

"This ......" Kaimo was momentarily dumbfounded.

"I think it might have something to do with the bugs themselves. Pasha continued, "Although it doesn't have the control of the multi-eyed monster, the instinct is still there, which is to capture and store its prey, and fresh blood is probably one of the triggers. 」

This speculation was quite reasonable, he thought to himself, the multi-eyed monster obviously didn't want food, so it probably didn't make much difference to them whether they were stored as they were or gelatinous.

"Then start testing the weapons as soon as possible," Roland commanded, "and now that you have the ideal raw materials, the next step should not take much effort." You can leave the rest to those kings, after all, you also said that the road to chemistry is still very long, and it is only right to pay attention to rest. ”

"Yes, Your Majesty. Kemo stroked his chest and said.

"I have one more thought. Pasha said suddenly.

"What is it?" Roland looked at her.

"Maybe you can piggyback on a special audience member during a weapons test. She swayed the Lord's beard.

Roland immediately realized who Pasha was referring to, "Is that guy still alive?"

Since he hadn't taken advantage of the chaotic period of soul fusion to ask for more information at that time, he didn't expect to pry open the mouth of the high-level devil again. Now in the hands of the Taqira witch, he either chooses to commit suicide or be tossed to death by the feud, he thinks that the other party has long turned into a wisp of ghosts.

"It didn't go on a hunger strike, as long as it sent food, it would eat it cleanly. Pasha was succinct.

This shows that it has no intention of dying at all.

Neither surrender nor confession.

It is waiting for the moment when humanity will be completely defeated and set itself free.

No matter how little hope there is, it is still holding on.

Is it because you think it's too worthless to die at the hands of bugs?

"I see," Roland said, raising the corners of his mouth, "then take it with you." ”
