Since the rise of the Western Turks, the countries of the Western Regions have begun to have two-faced diplomatic relations, of course, the Turks they can't afford to provoke, and they can't afford to provoke the Tang Dynasty, the lesser of two evils, they are more inclined to lose their trust in the Tang Dynasty, because the Tang Dynasty is a civilized country, it allows you to belong again, the Turks are different, their control methods are full of blood, dare not surrender, and the army will be directly wiped out. So in contrast, the countries of the Western Regions were even more afraid of the Tang Dynasty.

Therefore, for Li Er's question, Gao Buer thought for a long time and said: "The Western Turks have not rebelled once or twice, as long as they do not go west for a day, they may make a comeback, and now that winter is coming, they have calculated that the grain of the imperial court will be transported to the spring of next year at the earliest, at that time they have gasped and have the grain given by the imperial court, no one dares to guarantee that they will not go east, and there is also Tubo to guard against, and Goguryeo in the east is also very restless, and we need to be on guard, so as not to suddenly start an accident and we will be caught off guard." ”

"Uncle Huang is very worried, how about the emperor's nephew inventing the edict in the world according to the old system on the surface, and secretly preparing soldiers and horses?"

"Your Majesty is very thoughtful, so that even if there is nothing at the border, we will not be limited to passivity and admiration." This kid is becoming more and more handy at tricks, Gao Buji thought to himself.

Li Er was a little embarrassed to be praised, and said: "Uncle Huang praised it." ”

When your father's funeral is over, I plan to go to the Western Regions in person, first, to see the situation in the countries of the Western Regions, and secondly, with the solution of the sealing problem, the research and development of the steam engine is close to maturity, and the next step is to continue to update. ”

"Is Uncle Huang talking about coal? The imperial court has already sent someone to the grassland to look for it, you don't have to risk going to the Western Regions again, once there is a mistake, what is good? ”

"Don't worry, I'm not looking for coal on this trip, because the best coal is in the grassland, it's easy to find, and I'm looking for something that is more resistant to burning than coal."

"Is there anything in the world that is more resistant to burning than coal?"

"The world is so big, there are no wonders, there is indeed a thing called oil in the Western Regions, this thing does not die when exposed to water, high calorific value, is a very ideal fuel for the steam engine, once found, as long as the steam engine is slightly improved, the volume of the tractor can be greatly reduced, so that the tractor can be more portable and promoted."

Hearing that Li Er was full of energy, he always tirelessly pursued good things, because he saw the carrying capacity of this machine in the future, limited by the current transportation conditions, his army could not send too many people to the west, because to cross thousands of kilometers of the Gobi Han Sea, it was a great test for livestock, if he could add a tractor to a bucket according to Gao Buer's words, he could transport two or three thousand catties of goods, and then his army could hit the sky.

Gao Buer also figured out Li Er's thoughts, and he was also sure that Li Er would agree, his biggest purpose was to see the situation in the Western Regions, because the oil spring was in the Black Oil Mountain, that is, the Karamay in the future, as long as you go to the place, you can find it, which now belongs to the territory of the Western Turks, but since the Western Turks promised the Tang Dynasty to move westward, it has been assigned to the jurisdiction of the Anxi Metropolitan Protectorate.

Although Li Er was also very interested in Gao Buer's westward journey, he also had to consider Gao Buer's safety and the stability of the Western Regions, because the Turks and various tribes gathered there to wait for the food of the imperial court to start the westward expedition as soon as the food arrived, and at this time, there were no less than 300,000 people from various tribes in the Western Regions, and if the Turks really joined forces with the Tibetans, then they could gather no less than 800,000 soldiers and horses in the Western Regions in an instant, which was no joke.

"Since the imperial uncle has to go on a journey for my Tang Dynasty, then the nephew can't let you put yourself in danger, the nephew will appoint you as the capital of the west, and oversee the affairs of Anxi and Beiting Dadu Protectorate, and you can decide on your own major events, and the imperial uncle will go to supervise the northern expedition of the countries in the Western Regions on behalf of the imperial court, if the countries in the Western Regions have a second child, the imperial uncle can mobilize troops on the spot to destroy the enemy."

"Your Majesty, although we have to prepare for war, you must know that once the countries of the Western Regions decide to break the net, they will inevitably unite with Tibet and the Wei and Goguryeo in the east, and it is likely that a situation will be formed in which the whole world will attack Tang."

"I have long been unpleasant to see these countries, if the world really attacks the Tang Dynasty, then our uncle and nephew will join forces to conquer the world, see how fast their knives are, or our gunpowder is powerful."

"I'm relieved when you say that, after so many years, weapons made of gunpowder should already be able to be equipped with individual soldiers."

"Yes, the grenades and Gatlings you designed have been manufactured, and some of the armies have been equipped one after another, and the Gatling is worthy of being a life harvester, and I still remember the test site made of wild boars and cattle at that time, less than half a burnt of incense, thousands of pigs and cattle have all died, such weapons have never been seen in ancient times."

Gao Buji nodded and said, "The key is to do a good job of secrecy, while we have to develop new weapons, we also have to ensure that you may delay the leakage of weapons for a long time, so that we can maintain the absolute advantage of the weapon generation gap." ”
