"Tulun River!"

Soon, Princess Guanghua came with accurate news, and news came from a floating concubine that Fu Yun had taken the lead in leading three thousand cavalry to escape to Tulun River.

Merton looked solemnly at the rudimentary map in front of him, with only a bare dot on it, an oasis in the middle of the Tarim Desert, and Merton believed that the map was 100% inaccurate.

"Princess Guanghua shouldn't lie to us and deliberately let us enter this vast desert to die!" Cheng Yanjin looked at the location of Tulun Chuan, and couldn't help but cringe in his heart.

Eight hundred miles of Hanhai, deserted, no supplies, no water sources, only yellow sand everywhere, once you enter the desert, if you get lost in it, I am afraid that you will never recover.

Merton shook his head and said: "The news should not be fake, and at this moment, I am afraid that the one who wants us to find Fu Yun is none other than Princess Guanghua." ”

If Fu Yun is allowed to escape and ascend to heaven, I am afraid that Murong Shun's position as the khan will never be stable, and only when Fu Yun dies or is captured in Chang'an City, Murong Shun will have a chance to become the real Tuyuhun Khan.

Cheng Yanjin nodded, hesitating in his heart, the great credit is in front of him, but the risk is also great, this is not the edge of the desert in the Qaidam Basin, but deep in the Tarim Desert.

To chase, or not to chase!

Cheng Yanjin was entangled, the war had reached this point, and Fu Yun's 3,000 cavalry could no longer affect the overall situation, even if the squad returned to the dynasty, the whole army would be a great achievement.

But it is a great honor to be able to return with a subdued promise, and the benefits of chasing are certainly great, but in the face of the vast desert, even if the nerves are as thick as Cheng Biting Gold, they can't help but be afraid.

Once you step into the vast desert, whether you can return or not, I'm afraid it's also an unknown, I'm afraid that even if you have great military achievements, you can only cheapen Cheng Chumo, an unfilial son.

"Mo boy, what do you say!" Cheng Yanjin touched Morton next to him and asked.

Merton rolled his eyes and said indifferently: "You are the forward general, you have the final say, your old man will order to cross the eight hundred miles of Hanhai, and the kid will also sacrifice his life to accompany him." ”

Cheng Yanjin said angrily: "That's eight hundred miles of Hanhai, even the locals are daunting, we are not familiar with the place, once the direction of the pursuit deviates, it will be forgotten if we can't catch up, if we fall into the vast desert, I'm afraid there is a worry that the whole army will be wiped out!"

At this time, there is no precise navigation, once the direction is deviated, in the vast desert to find an oasis, I am afraid that it is like looking for a needle in a haystack, once the army does not reach the destination accurately, it will be lost in the vast desert, I am afraid that the whole army will be wiped out and no one knows.

Merton's heart moved: "If Uncle Cheng just wants to make sure that the direction is correct, then this matter is easy to do!" ”

"Seriously!" Cheng Biting Jin Fox looked at Morton suspiciously and said, "You kid, don't use the sun or the Big Dipper to fool the old man, I know more about these than you, the eight hundred miles of Hanhai, once the wind and sand rise, it will be a few days, and it will cover the sky and the sun, and what the human eye can see is only five steps, once we are lost and the drinking water is exhausted, then there is only a dead end." ”

Morton said loudly: "With such a pediatric method, how can the kid get an axe in front of Uncle Cheng, the kid's method can clearly and accurately confirm the direction even if it is dark and sandy." ”

As he spoke, Morton took out a palm-sized round box from his arms and handed it to Cheng Yanjin.

"What is this?"

Cheng Yanjin opened it and saw that in the middle of the round box, there was a long pointer, and the four directions of the pointer were in the east and northwest directions.

Merton said proudly: "This is a compass!" As long as we hold this weapon in our hands, not to mention the desert, it is the vast sea, we can come and go freely. ”

Merton took out the famous compass in later generations, the compass is very famous, but it is quite simple to make, the most difficult thing is probably the production of the magnetic needle Mojia Village gathered skilled craftsmen, but also to make a finished product.

"Compass?"

Cheng Yanjin took the compass in his hand, played with it carefully a few times, and suddenly discovered the beauty of the compass, no matter where he went, how to shake the round box, the arrow under the glass always pointed to the south.

Cheng Yanjin's heart moved, the reason why he lost his way in the desert was because it was all vast yellow sand, and there was no reference at all, but after having a compass, the south had been determined, and the east and west and the north were not clear at a glance.

"It's a brilliant thing!" Cheng Yanjin exclaimed, once he had this thing, Tang Jun immediately had the capital to crisscross the desert.

Merton smiled and said, "This time, Uncle Cheng doesn't have to worry about chasing the wrong direction!" ”

Cheng Yanjin laughed loudly: "Haha, Fu Yun, this time, where do you want to escape?" ”

With Cheng Yanjin's order, soon 3,000 left leading cavalry gathered and prepared to set off.

"Uncle Cheng is going to chase Fu Yun like this." Merton rode the Shadow with the firearms and rushed to the road.

Cheng Yanjin was puzzled: "What's wrong?" These are the old man's elite soldiers, and it is more than enough to pursue Fu Yun's lost dog. ”

Merton shook his head and said: "My Tang Army soldiers are naturally brave and invincible, but in the desert, no matter how brave the warrior is, they will die of thirst. ”

"One man, three rides!" Cheng Yanjin looked at the configuration of the firearms supervisor, and couldn't help but be shocked, the soldiers of the entire firearms supervisor were each one person and three horses.

Three horsemen were the most extravagant rations of cavalry, and if a cavalry had three horsemen at any time, he would be at ease, and no cavalry would be able to catch up with it.

However, at this moment, Merton's one-man and three-rider was not for a long-distance run, but to carry enough water and food, and all the horses carried a slow water bag on their backs.

Cheng Yanjin suddenly looked at Merton sarcastically and said: "Mo boy, I admit that your kid has some ghost ideas, but when it comes to marching battles, the old man is an expert in the army, looking at your compass, the old man will point you out, in the desert, there is no water supply at all, although one person and three horsemen can carry more water, but the water and food consumed by a horse are several times that of a person, and the consumption alone is enough to drag you down, not to mention the pursuit of Fu Yun, it is difficult to say whether you can rush to Tulun River." ”

When Merton heard this, he smiled and said: "What Uncle Cheng said is very true, it is indeed the old way, but the kid didn't say that he should bring all these horses back, and the real war horse that the cavalry really needs is just one horse." ”

Cheng Yanjin's eyes suddenly flashed, and he looked at the one person and three horsemen of the firearms supervisor in disbelief.

According to Merton's meaning, in order to reduce the loss of water along the way, the firearms superintendent will directly kill the horses to reduce the loss, and it is even very likely that only one of the three horses can come back.

The few firearms supervisors are only about a few dozen horses, and the one led by him Cheng Yanjin is three thousand cavalry, if according to Merton's suggestion, one person and three horses, that is nine thousand horses, and it is very likely that six thousand horses will be buried in the vast desert.

Needless to say, the value of a war horse is even more expensive, even in the land of Qinghai, the horse is not valuable, Rao is so six thousand war horses are worth at least more than a hundred thousand.

According to Merton's meaning, these 6,000 war horses, worth more than 100,000 guan, were to be discarded in the vast desert.

"Loser!"

After everyone heard it, they couldn't help but emerge Merton's famous nickname of the Tang Dynasty, this time the Mo family's defeat was not a small amount, but a full value of hundreds of thousands!
