On the way to the march, good news came from the front. Pen % fun % Pavilion www.biquge.info

On the 28th, Li Daozong, the king of Rencheng, defeated Dong. Turkic soldiers.

Everything was expected.

Therefore, Fang Xu, who knew the process and outcome of this war, was certainly not in a hurry.

Besides, with Ma Zhou, the future prime minister of the Tang Dynasty, as a strategist, and Su Dingfang and Liu Renliang leading the troops, will Fang Xu worry about losing the battle?

Of course not.

Unless Fang Xu dies by himself.

Only Fang Xu himself does not blindly command and wins steadily.

In Fang Xu's words, this trip is simply to pick up military merits.

As for fishing for military merits, there is no hurry, anyway, this war will be fought until next year.

Good things always come later, and so do military exploits.

Therefore, Fang Xu wants to get some secret weapons and give them to Dong. The Turks have a big move.

Seeing Fang Xu riding on a horse, he didn't go to war at all, and he turned the east. Turkic consciousness.

Ma Zhou asked, "Why do you want to take a detour to Changqing?" Su Dingfang and Liu Renliang were also puzzled.

As for why Fang Xu came, of course, it was oil.

Changqing Oilfield was the largest oil and gas field in China in later generations. The exploration area is mainly in the Shaanxi-Gansu-Ningbo Basin, with a total exploration area of about 370,000 square kilometers.

There is a large oil field not far from Chang'an.

Fang Xu also went to see it when he traveled to Xi'an at that time, and it was free on weekdays, and the tickets were free.

To say how Fang Xu knew so clearly, in fact, there is no half-dime relationship with the fact that Changqing Oilfield is the largest oil and gas field in China in later generations, and the father of Fang Xu, who had a good relationship with him in college, was an engineer in Changqing Oilfield.

As for what Fang Xu wants oil for, of course, it is to refine gasoline and give a ****** to the grassland people who rode war horses to the Central Plains to fight the grass valley, burn it, and tell them what a spark can fire the plains. Of course, gasoline burns in the prairie, and it is not a simple spark, but a monstrous firework, which is much more beautiful than fireworks.

"It's a pity that Li'er and Flower Dance can't see such beautiful fireworks." Fang Xu thought in his heart.

I have to say that General Fang Zhonglang's thoughts, uh, are very special, and he still wants to flirt with his sister.

As for refining petroleum into gasoline, for Fang Xu, it is still possible under rough refining. Fang Xu, who claimed to be a business elite in later generations, really studied petroleum refining, of course, it was only a momentary impulse, and this was also due to the engineer father of a classmate, who heard the old gentleman say a little.

Under the current conditions, according to the difference in the boiling point of petroleum components, Fang Xu can refine straight-run gasoline, kerosene, light and heavy diesel oil from crude oil, that is, the first processing process of crude oil. Then some or most of these semi-finished products are used as raw materials for crude oil secondary processing, which can do some simple catalysis and then distillation. Fang Xu can't figure out the advanced refining and refining processes that extend backwards such as catalytic cracking, catalytic reforming, and hydrocracking, so it's a big deal to study it slowly, and when Li Shimin sees the power of gasoline, there will definitely be a lot of financial, material and human resources.

If you really make ******, with black powder, even the cavalry of the armored forces, known as the cold weapon era, is just a chicken.

As for what Fang Xu was thinking, of course he couldn't say it.

Petroleum is a brownish-black, flammable, viscous liquid extracted from deep underground. The official name "oil" is based on this oil in the Northern Song Dynasty Shen Kuo's book "Mengxi Bi Tan" based on this oil "born in the sand and gravel of the water, mixed with spring water, and out of confusion".

Therefore, he could only pretend to be something and said to Ma Zhou: "The secret of heaven must not be revealed, when the time comes, you will naturally know." ”
