"boom!"

A loud bang!

A large pit was blown out of the mud, and the broken clay pots splattered everywhere, shooting around, hitting a large shield half a person tall, making a crackling sound.

Looking at the big pit nearly two feet above the ground, the alchemy alchemists around them looked straight and cheered.

"Really can it be? It's really possible?"

Gu Hongzi's excited dancer's fist looked at Qingxuzi with a little respect.

He has always been a transcendent for this senior. When he returned to the house yesterday, he kept thinking about how to achieve the explosive power that Pei Min said. He even did a lot of research and experiments, but found that it was ineffective in the end.

He increased his power by strengthening the amount of saltpeter, but he was unable to form an effective explosive power.

Apart from burning, it's just burning, sleepless overnight and nothing is gained.

But today, seeing Qingxuzi in just one night, he came up with a way to solve the combustion problem. He admired him and said excitedly: "It turns out that the younger generation has ignored the power of jars, saltpeter, sulfur, and charcoal that are emitted through combustion. There is no power at all. As long as there is a jar, the power of saltpeter, sulfur, and charcoal will burst in an instant. This is just like our usual medicine refining. The alchemy furnace must have a hole, otherwise the alchemy furnace will explode. The truth is the same."

Qingxuzi looked at this junior with a little surprise, and he couldn't help but feel like the younger generation pushed the older generation. He had his original plan, and his conversation with Pei Min yesterday, and he had today's black gunpowder, but he didn't expect Gu Hongzi had already had some insights and even saw through the key to the existence of the pottery jar.

Pei Min also looked at Gu Hongzi with some surprise. Based on his common sense in the 21st century, Gu Hongzi's explanation was nonsense.

The real explanation is explosion heat, explosion capacity, explosion speed and explosion pressure. When saltpeter is heated, it will quickly release oxygen, causing charcoal and sulfur to burn violently, instantly producing a large amount of heat, nitrogen, carbon dioxide and other gases. Due to the rapid expansion of the volume, the pressure will increase violently, causing an explosion.

Of course, Pei Min didn't remember these scientific explanations very clearly, and Gu Hongzi would definitely not be able to say them, but he vividly expressed the principle in another way.

Only a certain amount of space can trigger the occurrence of an explosion. This is the key to the explosion of black gunpowder. If there is no space, black gunpowder will only burn and will not explode.

Pei Min walked up quickly, and saw the explosion's remaining force going straight into the ground, about two feet away, and shook his head regretfully.

Qingxuzi, who followed behind, said, "Duke does it feel inappropriate?"

The remaining alchemists also looked at Pei Min in surprise.

Pei Min said: "Based on the amount of saltpeter we use, the power of this black gunpowder has not achieved the ideal effect. It is far from enough to open up gravel. The proportion needs to be adjusted." After a pause, he said: "Or try to use 1 nitrate, 2 sulfonium, 3 charcoal, or 2 sulfonium, 3 charcoal, or 2 sulfonium, 3 charcoal..."

He vaguely remembered that black gunpowder had a law of one, two, and three, but he couldn't remember what, two, and three.

Hearing Pei Min's words, Gu Hongzi shook his head and said, "Black gunpowder is a formula, saltpeter, sulfur, and charcoal is sure... But the ratio of one, two, three, it is impossible to make black gunpowder in any case. The main force of black gunpowder should be saltpeter, and even three or three is not enough to activate the explosion."

Qingxuzi also nodded and said, "Fellow Daoist Gu Hong said it well. Salter is the main force, and a ratio of one, two, and three cannot be achieved."

Pei Min frowned slightly, sure that he remembered correctly, and couldn't help but insisted: "Try it!"

Qingxuzi and Gu Hongzi did not refuse, and they also failed in their alchemy. They have long been considered common and are not anxious. The six people configured different formulas according to the ratio of one, two, and three.

This person has many strengths, and the six of them have only been a while, and they have already matched multiple copies according to the formula of one, two, and three.

The result is as Qingxuzi and Gu Hongzi said, no matter which one, it has no effect, and even the explosion cannot be achieved.

"Why is this?" Pei Min was a little stunned. Could it be that he remembered it wrong?

Gu Hongzi said: "I believe that if the power of black gunpowder is increased, saltpeter must not be less than sulfur, charcoal, or at least not less than their sum. The second should be charcoal, and the second is sulfur. The ratio of one, two, and three is impossible to make the black gunpowder needed by the Duke."

Pei Min said silently. After thinking about it, he suddenly closed his hands and said, "Try this, one pound of saltpeter, two taels of sulfur, and three taels of charcoal. Try this with one, two, three?"

Qingxuzi and Gu Hongzi's eyes lit up, and the two of them cooperated with each other!

A brand new formula was quickly made...

Mix the material in a small clay pot, bury it underground, and ignite the lead.

"boom……"

The loud noise finally came, and the feeling of a shaking mountain was like a bolt from the blue.

The dark smoke rose into the sky!

Sand and soil splashed everywhere...

The smoke dissipated, and a five-foot pit appeared in front of everyone...

Qingxuzi and Gu Hongzi were stunned. The numbers were obviously almost the same, but their power was more than twice as powerful.

"Is this the power of black gunpowder?" Qingxuzi realized why Sun Simiao had so firmly opposed him to study it. It was difficult to determine the pros and cons of this thing that appeared in the world. However, as Pei Min said, manpower could not reverse the general trend, nor could it change the overall situation. Even if there were no them today, with Pei Min's understanding of black gunpowder, there would be a day in the world.

"Haha, I feel that I remember correctly!" Pei Min danced his fists excitedly and said, "One, two, three, one is not one or two, but one pound... Master Qingxu, Master Gu Hong, I will give it to you here. You can make subtle adjustments based on the ratio of two, three, so as to make the black gunpowder more powerful as much as possible. With such a powerful weapon, you can open mountains and repair ridges and make the charter."

As he said that, Pei Min bowed deeply to several alchemy alchemists and said, "Pe Min only represents the tens of thousands of people in Longyou to thank you for the great masters."

Most of the people felt embarrassed. They had a good idea. Pei Min was the first hero who succeeded in the trial.

Everyone hurriedly replied with a humble gift, thinking that they had not made any contributions to the fine-tuning and improvement of the formula, they would spend some effort.

After Pei Min left, six people gathered for them to build a special laboratory for them and discussed how to fine-tune the formula more reasonably.

Pei Min no longer hesitated and wrote a memorial in person, and directly passed it to the Central Secretariat of the Tang Dynasty. The content was simple and not complicated, but it caused turmoil among the court and the country!

Opening Longshan Mountains, repairing Wushaoling Ridge, and breaking the sky.

The Silk Road has become the main source of finance for the Tang Dynasty. It is precisely because of the prosperity of the Silk Road that the finances of the Tang Dynasty have been in a healthy state.

The impact of Longshan and Wushaoling on the Silk Road is self-evident. Anyone with a discerning eye can tell at a glance, but for hundreds of years, no one dared to speak out, and it is not without reason.

Until today!
