To burn sulfur stone, first of all, utensils are needed. This thing can only be made by Han Yu himself. There is no way, and he can only cook a pot based on all the conditions.

The ignition point of sulfur stone is very high, so Han Yu must burn the pot to withstand high temperature. In order to make this pot that can withstand high temperature, Han Yu also specially found a lot of rare soil and added it, such as clay, porcelain clay, clay, etc., to increase its thermal conductivity.

After making the earthen pot and heating it completely, Han Yu put the sulfide stone in it.

Some things can only be discovered by doing them yourself.

Although the Taihu Light in Han Yu's mind has a detailed method for how to purify sulfur stone.

But when it was my turn to actually operate, I realized that the process was not as simple as I imagined.

First, when sulfur stone burns and melts, Han Yu must take the opportunity to select the impurities in it, and the process should be fast, otherwise it will be hot on the one hand. If you can't do it well, you won't get the last bit of good sulfur.

Without any iron tools, there are no chemical materials, it is undoubtedly extremely challenging to extract sulfur from high temperatures with a pair of hands and two wooden sticks.

Fortunately, the raw materials were almost endless, and Xu Qing brought a lot of sulfur stones in a short while, which was enough for Han Yu to squander.

After half a day of careful operation, when the ball of sulfur stone was selected by Han Yu many times and vaporized many times, it finally seemed that it felt a little sulfur. Han Yu felt a sense of accomplishment and fatigue suddenly emerged in his heart!

The sulfur extracted in this way is very rough and there are still many impurities inside, but Han Yu no longer wants to do it anymore. He does not require quality, as long as it can explode.

After a whole day and night, Han Yu finally purified enough sulfur.

Next, saltpeter is purified. The purification of saltpeter is much simpler than sulfur stone. Just soak it repeatedly in high-temperature water and filter it repeatedly.

You can only use a clay pot to boil water. Although this clay pot is very slow in heat conduction, it can eventually heat the water.

As a result, it took another day and night before Han Yu purified enough salt.

There is all the nitrification and sulfur, and the next one is black charcoal. Some people may think that this thing is very simple and just burn it with fire.

But in fact, black charcoal cannot be simply placed in the fire to burn, but it must be like a kiln to burn charcoal with good thermal conductivity.

what to do?

Han Yu could only use soil to make a small cave!

...

After three days, after several people performed their duties, Han Yu finally collected the raw materials for making gunpowder after processing day and night.

The next step is the most critical step, mixing these three raw materials together in a certain proportion.

This is not a simple mixture. It must be followed by the law of conservation of energy and strictly follow the ratio given by the light of Taihu Lake. Moreover, the black charcoal must be ground very finely, and the same is true for nitrate and sulfur.

Finally, it took another day before Han Yu combined enough gunpowder. Regarding whether these gunpowder could explode?

Han Yu was full of confidence. After all, everything was under the supervision of the Light of Taihu Lake. Even if it was almost done, it would only affect the power of the explosion!

Han Yu actually didn't expect these gunpowder to be very powerful. After all, there are too few materials in it, so it would be better to explode.

He only hopes that these gunpowder can blow up some pine trees on the hill and cannot withstand the impact of the river!

...

In the past few days, Han Yu's movements have been completed under everyone's eyes.

Without exception, no one could understand what he was doing. At this moment, seeing him walking towards the island with a pile of powder he had finally obtained, it immediately aroused everyone's curiosity!

Everyone followed him, wanting to see what happened, and the Di Shaman and the leader were even ahead.

The shaman looked good, she was cunning and could control her emotions well, but the leader and other tribesmen looked contemptuous.

What a joke, can these powders cure floods?

If this is simple, how many generations of people in our tribe can bother?

Let’s see how Han Yu ends up in a while!

The people of the Di clan thought so in their hearts!

Han Yu is about to carry out the last step, put the gunpowder in a bamboo tube and bury it into a hole dug by the monkey in advance!

This last step cannot be careless. If the gunpowder is not loaded well and tightly, there will be no explosion at all.

Moreover, this hole is also the key. If the location and depth of the hole are deviated, the overall effect of the explosion will be greatly reduced.

There are special blasting majors on earth, which shows the difficulty!

But fortunately, Han Yu had the help of the Light of Taihu Lake, and everything would be done according to his calculations.

After checking that the hole the monkey dug was not a big problem and finally filled it up, Han Yu used the remaining gunpowder to make a lead to connect the gunpowder.

Then he asked everyone to go away!

When the Di family saw Han Yu's last actions, he seemed to vaguely guess what he was going to do?

There was finally some incredible look in his eyes.

Although she didn't believe that Han Yu could cure floods in this way, even if this method only had a little effect, it would be a way!

And it is a way that shocks everyone in this world!

At this moment, it was obvious that the wisdom of the shaman was indeed not comparable to that of others. She could guess what Han Yu wanted to do.

But the other tribes, even monkeys, fat pigs, Sakyamuni, and Dizang, were still full of doubts.

Only the girl Xu Qing has inexplicable trust in Han Yu.

In her eyes, all the behaviors of the child prodigy were guided by the gods, so how could it not be cured even this small flood!

...

Ignoring the expressions of the others and without explaining anything to them, Han Yu directly pulled out a wooden stick from the fire to ignite the long lead.

A sound of swearing sounded...

Thank you for your hard work these few days, you will soon see results!

Soon, the lead ignited the first cartridge of gunpowder.

A rumbling sound scared everyone at the scene.

This gunpowder exploded smoothly!

Han Yu breathed a sigh of relief in secret.

Boom boom boom boom...

Then a few more sounds, Han Yu was clearly counting, and each cylinder exploded smoothly.

However, that hill is still very stable!

Everyone was scared to death by these explosions. At this moment, Han Yu in their eyes seemed to be covered with a mysterious veil!

Just like the gods they think of in their hearts every time they kneel down and worship!

But the leader's eyes quickly recovered, so he would not overturn Han Yu's impression in his heart so easily.

Although the explosion sounded, the hill was unshakable. The process was extremely magical, but the result was still useless!

The leader said with a smile, "Your actions are very frightening, but it seems that they have no effect on treating floods!"

"The hill did not look shaking at all. When the heavy rain fell, the river still rose!"

After the tribe leader said this, the eyes of the Di clans who looked at Han Yu changed instantly, without the worship he had just now!
Chapter completed!
