Qin Jin frowned secretly, the person brought by Huangfu Ke turned out to be that old way. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Info looked at the dress, and he immediately guessed that it must be Qingxuzi from the Taiqing Palace of Laojun Mountain.

Although he hated the gods and Buddhas, since the Qingxuzi had arrived, he couldn't frown coldly, so he politely invited him into the room. Huangfu Ke seemed to be very dissatisfied with Qin Jin's slackness on the side, and half-jokingly reproached: "The Venerable Master Qingxu dares to refuse even the invitation of the Son of Heaven, you are so ......"

Qin Jin just smiled awkwardly, and didn't answer, what could he say? Could it be that he couldn't explain it? Of course he couldn't, and he didn't disdain!

Qingxuzi put a cold ass on his hot face, but he didn't care at all, on the contrary, he sat down by himself, and it happened that there was a teapot and bowl on the table that had not been removed, he didn't care, he directly poured the bowl full of tea soup, and raised his neck and drank it in a big gulp. It wasn't until all the tea soup in the bowl was poured into his stomach that he put the tea bowl in his hand on the table, and at the same time raised his sleeve and touched the tea soup standing on his beard, and exclaimed with pleasure.

"Make the herbal tea in front of the Juntang comparable to the Heavenly Palace Immortal Dew!"

Qin Jin watched coldly to see what his intentions were, and now he began to be alarmist again.

"A real person is serious, but it's just a pot of cold tea soup, and it doesn't deserve such a reputation!"

Qing Xuzi looked at Qin Jin and smiled slightly.

"Qin Envoy Jun can tell me, why is he so disdainful of Lao Dao?"

Qing Xuzi got straight to the point and directly expressed Qin Jin's prejudiced heart, which made Qin Jin a little difficult to answer, but then he also laughed.

"Don't hide it, Qin never believes that there are gods, Buddhas and ghosts in this world, please forgive Qin for being rude!"

Qing Xuzi waved his hand when he heard this, "It's not rude, Zi is silent, strange and confused, Qin envoy Jun Kong is a disciple of the saint, and it is normal not to believe in Buddhism." It's just that the old Tao has a treasure, and he wants to sacrifice it to the king, and this treasure is beneficial and harmless to the world's major events!"

actually said that the treasures offered could influence the world's major events, Qin Jin felt that Qing Xuzi was really grandstanding, and his tone became more and more unkind.

"Since it is such a treasure, how can a real person come to Qin? Qin is just going to the county guard, how can he be deserved? Gao Xianggong is sitting in Tongguan, and when he is sitting in Chang'an today, how dare Qin not measure his own strength?"

Unexpectedly, Qing Xuzi smiled mysteriously: "Such a treasure is only a treasure in the hands of Qin Envoy, and in the hands of the Son of Heaven and Gao Xianggong, it is a waste!"

Qin Jin even felt that this was Qing Xuzi deceiving himself, he had seen a lot of this kind of deception in his previous life, how could he be confused by a few inexplicable compliments.

"In that case, please take it out and let everyone here see it......"

Finally, Huangfu Ke couldn't help pretending to cough anymore and reminded Qin Jin not to be too rude, after all, Qing Xuzi was here to offer treasures. It's just that Qin Jin only turned a deaf ear and still ridiculed Qing Xuzi.

Qing Xuzi is indeed well-cultivated, completely ignoring Qin Jin's various ridicules, and the smile on his face is still friendly and sincere. I saw that his arrogant sleeves showed his thin hands, and I don't know when there was a roll of leather paper held on it, and it was in front of Qin Jin.

Qin Jin took a roll of leather paper in Qing Xuzi's hand, and then gently unfolded it, and there were three big characters in his eyes, "Fu Huo Fang". Until "...... Two taels of sulfur, two taels of nitrate, three and a half coins of aristolochia......" all kinds of words came into view, and his heart beat violently again, where is this fire formula, isn't this the most primitive black powder formula?

If gunpowder is strictly discussed, it is indeed a weapon of the country to use it properly, but how does this old Taoist know in front of him? Qin Jin, who had always thought that he had insight into the overall situation, was also confused at this moment, and when he looked at Qing Xuzi again, his eyes were no longer as sharp as before, and he had a series of questions in his heart, and he couldn't ask them.

And under the cover of a series of questions, there is an irrepressible excitement. Qin Jin hadn't thought about promoting firearms in the army before, but he had always been unclear about the formula ratio of black powder, although he also knew a thing or two about the general ingredients, and mixed the raw materials together at will, and what he got was really far from the black powder in his impression.

Later, the war broke out, and Qin Jin did not put more energy on this, after all, it is impossible to build such a thing as firearms from scratch overnight, even if the test is successful, black powder is probably a long process, and whether the crisis faced by the Tang Dynasty can wait so long is still between the two.

"Where did the real person get this recipe for gunpowder?"

Qing Xuzi replied lightly: "The Fuhuo Fang is passed down by the ancestors! The old Tao is right, it is a treasure of the country for the envoy!"

Qin Jin is not a hypocritical person, since he was said by Qing Xuzi, he nodded generously and acknowledged. The reversal between the two was so fast that Huang Fu Ke hadn't figured out what was going on? Qin Yuanjun, who had always hated gods and Buddhas, actually nodded in agreement with Qing Xuzi's statement, which was really a strange thing.

Qin Jin opened his mouth and asked again: "Dare to ask the real person, can you know the things contained in the fire side, how to use them?"

He wanted to find out how much Qing Xuzi knew, so he asked. Qing Xuzi sighed softly, "It's not a secret, the old way also has to be manifested by the ancestors, and tell this party to be dedicated to Qin Envoy, it will be of great use, as for how to use it, Lao Dao also wants to ask Qin Envoy Jun to solve his doubts!"

In Qin Jin's opinion, there is no way to find fault between truth and falsehood, and it is another effect when it falls on Huangfu Ke's ears. I saw him ask in amazement: "Qin Envoy, what is contained in this fire square, you, do you really know how to use it?"

Restraining the smile on his face, Qin Jin nodded slowly. At this point, it is tantamount to admitting that he knows how to use it. Huangfu Ke could no longer suppress the excitement and excitement in his heart, even though he was already an old man over half a hundred years old, he still bounced up from his seat and paced back and forth in the room.

"Could it be, is it true that God protects itself in the dark? God protects him so much, why should he worry about the traitor not being removed?"

In the excitement, he muttered to himself, almost entering a state of forgetfulness. On the contrary, Qing Xuzi, who had been talking endlessly, didn't say a word at this time, and only looked at Qin Jin quietly, as if waiting for him to say something.

Qin Jin looked at the proportion of raw materials on the fire square, if this could achieve the desired effect, it would save him at least a year or two of effort, and in this way, it would be possible to produce some simple and easy-to-use firearms on a large scale.

Regardless of the origin of Qing Xuzi's old way, Qin Jin was at least one thing certain, this person had no ill will towards him, since he was unwilling to tell the story behind the Fuhuo Fang, why should he ask it? The important thing is that according to the proportion of materials contained in the Fuhuo Fang, he can really prepare a useless black powder.

So, Qin Jin immediately ordered someone to conduct a matching test, but he still made a little change to the Fuhuo Fang and changed the aristolochia directly to charcoal, because the effect of charcoal is far better than air-dried aristolochia powder.

After changing the aristolochia to charcoal, Qingxuzi personally conducted a matching test, and in just half a day, he made half a basket of black-brown powdered gunpowder.

Qin Jin picked up the wooden spoon and personally took out a spoonful, put it on the stone slab, and then Qing Xuzi gently touched the firewood branch that had been burned to red, and a burst of white smoke rose steeply, and in the blink of an eye, the gunpowder powder burned cleanly, leaving only the stench of burning sulfur all over the courtyard.

This was exactly what Qin Jin needed, and it was really an unpredictable surprise for him.

"Quick, go to the treasury and count how much sulfur and saltpeter there are!"

In addition to being excited, Qin Jin did not forget to send people to count the raw materials in the treasury of the capital, and he wanted to know at the first time how much black powder could be made from the inventory in Jiangzhou.

At this point, Qin Jin no longer thinks that Qing Xuzi is a god who pretends to be a ghost, in his eyes, he is clearly an engineer who is proficient in preparing gunpowder. Therefore, this veteran must not be allowed to leave, at least let him train a group of technicians who can master the gunpowder mixing process before he can be released.

"I hope that the real person can stay......"

Qin Jin had only said half of the kind words that Qin Jin had retained, and Qing Xuzi interrupted him happily.

"The envoy is booming, and the old way is not leaving!"

……

The unexpected joy of the successful trial production of gunpowder completely changed Qin Jin's previous conservative plan, and a bolder and more risky plan took shape overnight. Of course, if the plan is successful, the fruits of victory will be even greater.

Qin Jin personally drew the drawings and invited craftsmen from the city to conduct trial production. He chose two of the simplest and most powerful firearms among the many firearms that later generations offered. One is a thunderbolt cannon, and two are pear flower guns.

The Thunderbolt Cannon was also called the Blossom Thunder in later generations, and the Pear Blossom Gun was a powder keg that could fire scattered bullets, which was tied to the front of the gun body and fired suddenly before engaging the enemy, although the damage caused was extremely limited, but the shock to the enemy was enough to destroy their will to fight, thus shaking the morale of the army.

Moreover, these two firearms have also been tested in actual combat in the Song and Ming dynasties, and Qin and Jin only need to imitate them. To tell the truth, these two firearms are not at all difficult except that the formula of gunpowder is difficult.

After a long day of hard work, the first batch of test products was finally placed in the back garden of the PCPD. Qin Jin has been deliberately isolating news from the outside world out of the need for confidentiality. Many people in the army and the public office knew that Qin Envoy Jun had obtained the treasure of Qingxu Zhenren, but it was not clear what it was.

At sunset, several earth-shattering explosions came from the back garden of the office like thunder, and the listener even felt that the ground under his feet was trembling again and again, and for a while he was both frightened and full of curiosity about the things in the back garden of the office.

"I heard that the Qingxu real person of Laojun Mountain came to see our envoy, and he also brought a magic weapon that can defeat the enemy......

"Could it be that you can invite the magic weapon of the thunder male lightning mother, or can you scatter beans into soldiers?"
