This canyon is extremely well guarded by Bai Hui, because it is the most terrible tool of war.

Bai Hui, a scumbag, has regretted it for a full year.

If he knew he had a chance to cross over, Bai Hui would have studied very, very, very hard in middle school chemistry class.

It's a pity that a scumbag is a scumbag.

However, Bai Hui has gold as a scumbag, so Bai Hui tried to make more than 800 formulas in different proportions, which are nothing more than charcoal, sulfur, and saltpeter.

At present, the most successful formula on Bai Hui's side is really compared with later generations. It is estimated that any black workshop that makes firecrackers can crush Bai Hui.

But!

This is the Warring States, and even firecrackers can become a weapon of terror.

The first craftsman in the valley came to King Qin with a tray in both hands.

A small, snow-white dish on the tray contained a small pile of tiny black particles the size of a fingernail.

King Qin, Wei Ran, Bai Qi. After the three of them stared at the pillar of incense for a full time, King Qin turned around and asked Bai Hui, "What is this, it is worth it when you are so tightly guarded." ”

Bai Hui raised his head and looked around, and then said to King Qin, "Your Majesty, choose a boulder at will." ”

"Okay, that's it." King Qin casually patted a one-person-high bluestone nearby.

The guards in the valley carried the bluestone to the test site in the valley, where there was an open space about the size of three football fields, with many gravel, rubble, and wild grass.

The two soldiers quickly dug a small hole in the ground and placed a cloth bag in the pit.

Bai Hui knew better than anyone what it was, almost five kilograms of a pack of primitive, incomparable to the power of explosives in later generations, even the black powder used to make firecrackers.

Again, this is the Warring States, and this thing is already terrifying.

The lead wire was connected, and the bluestone was put on.

Bai Hui remembered that there was a post in later generations that said that adding a little copper oxide would make the black powder particles more powerful. However, at the moment, the most perfect formula for black powder has not yet been trial-produced, and copper oxide is easy to do, that is, patina, but how to add, how much to add, etc., there is no clue.

Therefore, there is only this gunpowder that has been tested more than 800 times and is made with the most effective formula.

There is still a huge room for improvement.

Seeing that the soldiers were ready, Bai Hui pulled King Qin to hide behind a boulder, and dozens of guards had already taken out heavy shields to protect King Qin, leaving only a gap for King Qin to see the bluestone.

"No, the widow wants to see clearly." King Qin pushed away the guards.

Bai Hui roared: "Your Majesty, this thing is infinitely powerful, such a big bag is enough to make the walls of a small city collapse in an instant. If you really want to see clearly, you can only go up the cliff and see it from a distance. ”

"Then go up the mountain."

King Qin felt his heart clenched, that thing could actually destroy the city wall, so terrifying?

When King Qin, Wei Ran, and Bai Qi all chose a good position, Bai Hui still arranged for someone to protect him at any time with a leather shield, and then waved the flag to signal the start.

King Qin saw it clearly, and saw that after a person lit something with a torch, he quickly escaped into a pit, and then pulled up a wooden plank to block the pit.

Suddenly, there was a loud bang.

The bluestone, which was more than one person high, was more than three feet above the ground, and then cracked.

Split into four pieces.

"This ......," King Qin was stunned.

Wei Ran was stupid when he saw it.

Wei Bai Qi, a smile appeared on his face, Bai Qi clearly knew the power of this thing, dug a pit in the enemy city wall and buried dozens of bags, I believe that the city wall of several zhang will collapse in an instant.

At this time, Bai Hui held a copper horn and shouted: "Can I use the sharp weapon I asked you to design?" ”

"Yes!"

"Straw Man!"

On the test ground, after dozens of straw men wearing old-style Qin army leather armor were put on the table, a strong Qin army took a wine jar containing two catties of wine and rubbed it on the torch, and then threw it at the straw man vigorously.

There was another loud bang, and the straw man was a foot away from the altar and was blown up.

Bai Fei quickly descended the cliff, almost ran to the test site, pulled up a straw man and looked, only to see that the straw man's leather armor was pierced by pieces of sharp small iron pieces.

The sticks supporting the straw men were also broken.

"Awesome!" Bai Qi was overjoyed and laughed.

King Qin and Wei Ran didn't move, they were already frozen.

If there are a thousand such jars, tens of thousands of enemy troops will not be able to resist it, how terrifying.

Wei Ran's open mouth finally closed, and he turned his head to look at King Qin: "Your Majesty, the defenders sent by Bai Hui don't seem to be many at all. ”

"Not much, not much at all. If such an object is obtained by the Six Kingdoms of Shandong, it will be a disaster for my Great Qin. ”

At the test site, Bai Hui said to Bai Qi: "This thing can really be used on the battlefield, and it is estimated that there will be tens of thousands of gold, or even hundreds of thousands of gold, thrown in." And at the moment, the process has not been studied, it is just handmade, the cost is huge, and it is not suitable for use on the battlefield. ”

Bai Qi turned his head violently and grabbed Bai Hui's clothes: "Don't say 100,000 gold, even a million gold must be completed." ”

"That's right, a million gold is going to complete this thing." King Qin's voice came from behind the two of them.

Bai Hui shouted: "Come on, demonstrate the ultimate killing weapon for the king." ”

Bai Hui's ultimate killer, if modern people in later generations see it, this thing is not as good as salute fireworks, and it is not even a toy.

But at this time, it is indeed the ultimate killer.

An old piece of wood was hollowed out, an iron hoop was added, and then gunpowder was loaded, and what was stuffed in front was not an iron ball, but just a rattan ball made of an old tree and rattan.

The charge is also very small, only about one catty or two.

Bai Hui held a torch: "Your Majesty, please light a fire, this is not dangerous." ”

"Good!" King Qin's face was solemn, holding the torch with both hands and approaching the lead, and when the lead was lit, there were immediately two guards, one left and one right, who protected King Qin with leather shields.

With a single sound, the fist-sized rattan ball flew out hundreds of paces with a single breath.

Bai Hui said: "Use bronze to cast a giant cannon five times larger than this, and then shoot not a rattan ball but a solid iron ball, and shoot it three miles, or five miles away. I don't know if this kind of mass killing weapon can be used in my Qin army? ”

Bai Hui asked a nonsense.

Bai Qi asked rhetorically: "Can you make this thing?" ”

"Just because you can't do it now doesn't mean you won't do it in the future. I have the best bronze caster in the world, and if I try slowly, I can always make it. ”

Speaking of this, Bai Hui turned around: "Your Majesty, this is the artillery execution." I took twenty catties of gunpowder and threw it on Wen Xi, and I still didn't believe that she was stronger than that bluestone. ”

King Qin turned around and looked at the bluestone with a cold face: "The widow is not allowed, about Wen Xi's execution, the widow thought that he should use arrows to kill, and a thousand strong crossbows were aimed at her and shot at her alone, the widow was interested in taking a look, and could he still recognize her." The so-called artillery execution is not allowed. ”
