Yang Yuanqing took the small bowl, the liquid in it was a bit like peach wine, light brown, clear and transparent, exuding a strong taste.

"It's kerosene!" Yang Yuanqing smelled this smell all of a sudden.

But it is not as foul-smelling as kerose, nor is it as viscous as black syrup as kerose, which is more like wine, and although it is not as transparent and light as gasoline in later generations, it is much better than kerosene.

"Your Highness, this is what the two of them refined, the raw material is the same fire oil as the Sui army, but this light fire oil is more intense and burns more quickly, and this fire oil is commonly used in the Roman army."

Combas lit a small ball of paper and threw it into a small bowl, only to hear 'Boom! With a bang, the raging fire ignited, not at all like the smoke billowing from Sui Jun's oil, and Yang Wei next to him was also dumbfounded.

Kang Bas proudly introduced: "This is the fire oil that the two of them refined in Kangguo, and it burns very violently. ”

Yang Yuanqing stared at the burning oil in the bowl, without saying a word, now after the Sui army's oil was extracted from the well, after a simple precipitation in the pool, it was directly used, almost a kind of original oil, the smoke was too big, the combustion efficiency was not high, and there was even a situation where the rocket was not burned at a long distance.

On the one hand, it is true that the quality of the fire oil produced in Yan'an County is not very good, too viscous and thick, and on the other hand, because the fire oil has not been refined, this problem has always troubled the Sui army.

After the Tang army also extracted the fire oil from Bashu, the quality of their fire oil was obviously better than that of the Sui Dynasty, and the combustion power was greater.

The road is one foot high, the magic is one foot high, the Tang army came from behind, and has surpassed the Sui army in the use of fire oil, and they even invented the fire oil injector.

Tang Jun's fire oil injector actually uses the principle of syringe backlog. Squeeze out the oil in a wooden box. The principle was very simple, but Sui Jun could not use this fire oil injector because it was too viscous and easy to solidify and seal.

The fire oil refining technology brought by Kangbas is undoubtedly a charcoal in the snow, and it came too timely, Yang Yuanqing was overjoyed in his heart, at this time, his heart was no longer on Luo Shixin's wedding, and he wanted to go to the ordnance prison immediately.

Yang Yuanqing instructed Yang Wei a few words. After returning to the wedding banquet, he sat back in his seat and whispered to Pei Minqiu: "I want to go back to Jinyang Palace, do you want to go back together?" ”

Pei Minqiu was stunned for a moment, did he have to leave just now? At this time, Father Luo hurriedly stepped forward, bowed down and saluted: "Shixin sent someone from the Qin Mansion to send a message that the bride is going to put on new makeup, and I'm afraid it will be very late to come back." His Highness is free to stay. Shixin thanked His Highness for coming to the wedding. ”

This news came too timely, Yang Yuanqing smiled slightly: "Okay then!" Jinyang Palace still has important matters to deal with for me, so I will leave first. ”

"In that case, Your Highness, please come with me."

Yang Yuanqing and Pei Minqiu did not leave from the main gate, which would alarm too many people, and the two of them, under the protection of the guards, followed Father Luo to the back door and left quietly.

The wedding banquet was still lively. Drinking and fist-fighting, noisy and lively, no one noticed the departure of the king of Chu......

Jinyang Palace Ordnance Supervisor, more than a dozen ordnance supervisor officials rushed back to the official office, ordnance superintendent Han Yun, and young superintendent Zhang Lei also arrived.

At this time, it was getting late, and the night was shrouded in the weapons monitoring test. Yang Wei also arrived with Combas and two craftsmen from Eastern Rome, who brought more than a dozen pots of refined fire oil.

Several soldiers poured the oil into an iron pot, filled half the pot, and placed it a hundred paces away, and in an iron pot next to it, they also filled half a pot of oil.

The two archers stood on the high platform, holding bows and arrows, waiting for Yang Yuanqing's order, Yang Yuanqing also stood a hundred steps away, staring at the two iron pots in the dark, and there were torches next to the iron pots.

Such a scenario has been rehearsed more than once, a rocket is fired into a pot of oil oil, and if the oil is shallow, only about one or two inches, do not drown the flames on the arrow, then it can burn.

But if the oil is more than three inches thick, and the viscous and heavy oil floods the rocket, it will be difficult to burn, and what about today? The thickness of the two pots of oil was more than four inches.

Everyone's hearts were very nervous, but they were also full of anticipation, and a lieutenant rushed to Yang Yuanqing, knelt down on one knee and reported, "Everything is ready, please give the order from the manager." ”

Yang Yuanqing nodded, "You can shoot arrows!" ”

The lieutenant stood up, held aloft the command flag, and shouted: "Prepare for archery!" ”

Next to the two archers, a soldier with a torch ignited their rocket, and the arrows burst into flames.

The archer slowly pulled out the bow, and as soon as the bowstring was loosened, two rockets rose into the air, and the two flames drew an arc in the air, and shot into the oil pot accurately, the speed of the arrow was too fast, and the flames on the arrow instantly submerged into the oil of fire, 'Shhhhh With a bang, the flame went out, and the iron pot on the left did not burn, as in the previous test.

But the rocket went out not to disappoint, and it was strange for everyone to be able to burn up.

At this time, everyone's eyes were fixed on the iron pot on the right, this is the focus of today, whether there can be a breakthrough in the new fire oil brought by the Hu people in the Western Regions.

The rocket shot into the iron pot, and in the blink of an eye, the iron pot 'boom!' The ground burned, the fire burned, and the crimson flames licked into the night sky, and there was no billowing black smoke.

There was no sound in the test ground, there was no cheering, everyone's eyes were very complicated, the Sui army's fire oil was extinguished, but the fire oil brought by the Hu people in the Western Regions was burning.

Yang Yuanqing slowly stepped forward and said to everyone: "The ruler is long, the inch is short, the Westerners' fire oil is indeed more powerful than us, we should admit it, but we have to learn, we have to learn how they refine the fire oil, this is the reason why I called everyone together, let's go to the council hall!" ”

Everyone came to the council hall and sat down, Yang Yuanqing smiled and introduced Kangbas to everyone, "This Sogdian uncle was also the Sui army at the earliest, when I was the fire chief in Fengzhou, he was a small soldier under me, and later did a tea and wine business, his daughter is also the wife of General Yang, this time he came back from Sogdia and brought two Western Great Qin people, who were once craftsmen in the Great Qin army, and the fire oil we see today is refined by them." ”

Yang Yuanqing waved his hand to Kangbas, who stepped forward and arched his hand to more than a dozen ordnance supervision officials, and said with a smile in extremely proficient Chinese: "Everyone, in Lower Kangbas, in fact, he is just a small Hu merchant, His Royal Highness King Mengchu can see it, I am deeply honored, due to the problem of language, I will give you a brief introduction to the process of refining fire oil in the Western Regions, when they were refining, I was also present and saw it very clearly." ”

He introduced to everyone: "In fact, refining oil is very simple, divided into four steps, the first is precipitation, after the oil is extracted from the well, you need to dig a sedimentation tank, first precipitate impurities, and now we have the same method." ”

Combas took a sip of tea and said, "The second is filtration, which uses a very fine net to filter out the viscous objects in the oil of the oil, and then the third and most critical step. ”

He held up a picture, the picture is a spherical container, there is a tube on the container, "This is an iron urn, which is filled with fire oil, and then the fire is burned below, after the fire oil boils, it will steam out a relatively clear fire oil, and it flows out along the pipe, in fact, it is the same thing as steaming wine, and the fourth step is the same as the third step, and then steam it a second time, so that you can get the fire oil you see today." ”

Kangbas's introduction made everyone nod again and again, in fact, it was really simple to say it, at this time, Yang Yuanqing said to everyone: "Everyone roughly understands the method, but it is not enough to understand, the key is to do it, starting tomorrow, in the west military camp outside the city, conduct experiments and make all kinds of equipment, where is Young Eunuch Zhang?" ”

Zhang Lei, the young superintendent of the Ordnance Prison, immediately stood up, bowed down and saluted: "Your Highness, you are in a humble position!" ”

"You are responsible for this matter, I hope to see the new fire oil refined by our Sui army within a month."

Zhang Lei hurriedly bowed down and agreed, "Obey orders!" ”……

The night was already deep, and heavy dark clouds covered the sky, making the night extremely dark, and the two Roman craftsmen were sent to the Honglu Temple building to rest, while Kang Basi followed Yang Yuanqing to the official residence of Ziwei Pavilion.

The guards lit the candles in the official room, and Kang Bas followed Yang Yuanqing into the room, Yang Yuanqing smiled and said, "Feel free to sit!" ”

Although Kang Basas has an old relationship with Yang Yuanqing, he is an extremely shrewd businessman, who knows how to respect and order, he knows that Yang Yuanqing is already the king of Chu, almost the lord of a country, he can't really be casual, that will bring him death.

He must maintain enough respect, he knows that the Oriental people are very polite, etiquette is respect and order, and only when he obeys this etiquette can he get the corresponding dignity.

He said respectfully: "Combas doesn't dare to be casual!" ”

Yang Yuanqing had no choice but to formally invite him to sit down, and ordered his soldiers to serve tea, and then asked: "I want to know about the situation of the Western Turks, how much do you know?" ”

"I know one thing, the Western Turkic Khan was indeed a very eloquent man, and he reunited the fragmented Western Turks, from the west of the Green Mountains to almost the entire Sogdian region, which he controlled, and he set up officials in the Sogdian countries to collect taxes, obtain Western iron weapons, and arm his army, which is said to have 300,000 troops."

"What about the situation east of Green Ridge?" Yang Yuanqing asked again, he was very worried that the Western Turks would expand eastward again, and if the Western Turks expanded eastward, it would inevitably infringe on the interests of the Great Sui.

Kang Bas shook his head, "The situation east of the Green Ridge is not optimistic, it turns out that the Tiele tribes are under the leadership of the Chibi, and the Western Turks are confronting, but the Chebi is gradually declining, and the internal struggle is very strong in order to fight for the leadership of Tiele, from my personal feeling, the Western Turks are likely to expand to the east, Your Highness, with all due respect, the Western Turks' invasion of Yiwu County is already an inevitable thing." ”
