Chapter 49 The Effect is Simply Explosive
Regarding the guess in his heart, Gu Yu didn’t think there were too many possibilities.
This is because that kind of thing needs to be processed and purified to become a white crystalline substance.
However, these white crystalline substances clearly did not involve so much trouble, but formed naturally…
However, there was another point that made Gu Yu disbelieve… If his guess was correct, then the situation would be dire after the cave was heated!
With this thought, Gu Yu didn’t continue to overthink. Whether it was as he thought, he had to experiment first.
Perhaps he was too sensitive.
This white crystalline substance was just a product of nature, with no functionality at all.
Thinking this, Gu Yu took a flint to light the candle, then placed the soybean-sized white crystalline substance on an iron片 to heat it, while nervously observing the situation.
At first, nothing happened, making Gu Yu feel like he was being overly cautious.
However, after the iron片 was heated, he heard a sound of something shattering, which made Gu Yu immediately use his consciousness to control the heated white crystalline substance and send it directly towards the empty farmland.
Immediately, a ‘bang’ sound occurred, and a small pit was blown in the farmland.
After walking over to take a look, Gu Yu couldn’t help but twitch the corner of his mouth, thinking that if such a granule of soybean size had such power, then a head-sized one would be enough to blow away his entire space.
Feeling a bit of lingering fear, Gu Yu extinguished the candle and decided… he would only store these white crystalline substances in the corner of his space from now on, and would not bring them into this small world again, to prevent any unexpected situations.
After all, in the small world, both people and animals could move, unlike in the space where they were static, and even time was frozen.
“Mengyao, I feel like I’m dreaming. Hit me and see if it hurts.”
After Gu Yu removed the table, he sat on a chair, looking at the white crystalline substances placed on the ground. His heart was as if a seasoning jar had been overturned, filled with mixed emotions!
He never dreamed of obtaining such a thing, but now he had actually encountered it, and there was a whole cave full of white crystalline substances.
This was simply a huge treasure trove!
Even if it wasn’t the treasure location marked on the human bone treasure map, for Gu Yu, this place was even more important than the treasure on the treasure map!!!
Just for making gunpowder in the future, these white crystalline substances… oh, now they should be called natural potassium nitrate, would surely shock everyone.
Perhaps, the era of firearms was about to arrive.
Thinking about these things with surging emotions, Gu Yu’s expression changed repeatedly, until Gu Mengyao directly raised her hand and cupped Gu Yu’s face, making Gu Yu look at her.
“Yu, you need to cheer up! Even if we didn’t find the buried treasure, what we saw and heard along the way is a beautiful memory. Don’t get stuck in a rut anymore!”
While Gu Yu was excited, Gu Mengyao looked at him with worry.
Gu Mengyao didn’t know the use of these white crystalline substances, she only thought that Gu Yu was excited because he couldn’t find the treasure, and worried that he would take drastic actions, making Gu Mengyao wonder if she should just knock Gu Yu unconscious.
However, after thinking about it, Gu Mengyao gave up the idea of knocking him out.
If Gu Yu fainted in his space right now, there might be very serious consequences.
Therefore, it was better to persuade him properly!
“Of course, I know you must be very unwilling, but you can’t let yourself feel upset. At worst, we can go out and have a good fight! It’s okay even if you want to find test subjects to try out medicine, as long as your mood improves, it doesn’t matter what you do.”
Facing Gu Mengyao’s worried gaze and listening to her domineering declaration, Gu Yu felt a sense of both wanting to laugh and cry.
Didn’t Gu Mengyao hear the explosion sound from the farmland just now?
Well, the sound was relatively small, but the explosion crater was very obvious!
If Gu Mengyao knew the power of potassium nitrate, she would probably be very happy too!
Thinking this, the corners of Gu Yu’s mouth curved upwards slightly, preparing to tell his little wife about his discovery.
Ever since he was threatened by the Witch Priest, Gu Yu had been thinking about what kind of powerful weapon he could use to deal with him.
Unlike the petty squabbles of others, the Witch Priest, as a powerful superior, was not someone who could be easily dealt with.
Not to mention that over the years, the Witch Priest had annexed many countries, and his strength was extremely formidable.
Linfeng Kingdom was currently fine, it was only because the Witch Priest had taken a fancy to Bai Qian that he chose to slowly engulf it, rather than attack directly.
It was like a frog being boiled in warm water.
If he weren’t worried about being lectured by Gu Mengyao, Gu Yu would have wanted to tie up Bai Qian directly as a hostage to negotiate with the Witch Priest.
Amidst these worries, it was like the calm before a storm; everything was fine for now.
Even the people sent by the Witch Priest seemed easy to deal with for Gu Yu…
Originally, even after the treasure hunt ended, Gu Yu would still continue to worry when he returned to the capital.
He didn’t want his little wife to be in danger, so he had to think of a foolproof plan in advance.
And now, he had found it.
These white crystalline substances of potassium nitrate only needed to be mixed with sulfur and charcoal to produce gunpowder.
When that time comes, throwing some onto the battlefield will have an explosive effect!
“Mengyao, I’m telling you, this treasure hunt is really worth it!!! This white crystalline substance is called potassium nitrate, and when heated…”
Facing Gu Mengyao’s confused gaze, Gu Yu quickly began to explain.
After explaining for a long time and then conducting an experiment with a small piece of potassium nitrate, Gu Mengyao finally understood the power of potassium nitrate and became very interested in the gunpowder that Gu Yu mentioned.
If there was truly such a magical thing as gunpowder, then the army would no longer suffer heavy casualties.
Soldiers would also have the opportunity to go home and reunite with their parents and loved ones.
Even wars might not happen.
Linfeng Kingdom would become increasingly powerful, allowing people to live in peace and contentment.
In an instant, Gu Mengyao thought of many things.
Upon realizing the importance of the white crystalline substance, Gu Mengyao immediately showed an impulse to go outside and work as a miner to chisel the wall. Gu Yu quickly pulled her, the anxious little wife, stating that they couldn’t act rashly yet.
There were still people outside who hadn’t been dealt with!
“Mengyao, I’ll go out first. After poisoning everyone outside, we’ll come out to collect the potassium nitrate crystals.”
After smiling and saying this to Gu Mengyao, Gu Yu asked her to wait patiently in the space, while he left the space and returned to the cave.
