Cheng Yanjin didn't comment on Li Yan's judgment, but he was a little difficult to agree with in his heart.

It is normal for Li Yan to be able to accurately judge the damage caused by the snow disaster in the Monan Grassland and the remaining combat strength now, after all, the two sides just fought more than a month ago.

But how did Li Yan know about the situation in Mobei? Intuition or Observation?

It is too risky to rush into the army without any direct evidence.

Cheng Yanjin had the heart to persuade Li Yan not to be greedy, as long as he swept Mo Nan, it was enough, but he didn't say it after all.

This time it is obvious that Li Shimin is giving Li Yan an opportunity to create merits, in case the snow disaster in Mobei is really worse than that in Monan, then this is indeed an excellent opportunity for Li Yan to ascend to the sky in the court, and even leave a name in history.

"That's it, it's a big deal to let the army quickly assess Mo Nan, and then follow closely behind to forcibly conquer Mo Bei."

Cheng Biting Jin was heartbroken, and simply gave up persuasion.

The strength of the four cities, plus the manpower mobilized from Longyou Dao and Guannei Dao, was close to 30,000.

Even in its heyday, Mobei mobilized a maximum of 50,000 soldiers and horses, and it took time to assemble from various departments.

When the time comes, 30,000 troops will force the Gobi, even if the soldiers and horses led by Li Yan suffer heavy losses, Cheng Yanjin will be sure to save Li Yan.

Anyway, Li Shimin also said that this battle is fruitless and there is no punishment.

Li Yan has a guaranteed record in the Monan Grassland, which is enough to seal a founding county uncle.

After Cheng Yanjin made up his mind, he began to communicate with Li Yan about other details of the troops.

The so-called soldiers and horses have not moved, and the grain and grass go first.

In addition to fighting tough battles, there are many times to consider.

These details are what Li Yan couldn't estimate, and he also needed to have a good exchange with Cheng Yanjin.

As the day passed, a series of detailed plans were finalized by the duo.

After determining the phased purpose of each marching battle, the two began to reorganize the army.

There are more than 5,000 people in the Fengzhou military camp who need to be coordinated (the soldiers and horses lost after the battle to defend the city have not been replenished), and the southern camp has 3,000 people brought by Cheng Yanjin from Zuowuwei in Chang'an to be arranged.

In a few days, there will be soldiers and horses from the three cities of Ganzhou, Quanzhou and Shazhou to arrive, and then there will be people from Longyou Road and Guannei Road.

All in all, these few schedules will be very busy, after all, the management task of the army Li Yan has been handed over to him, and Li Yan himself is only responsible for leading the cavalry as the vanguard to open the way at the front.

Compared with managing the army, Li Yan is obviously more experienced in battlefield fighting.

The time of five days passed quickly, and the soldiers and horses from all sides had already come to assemble outside the city of Fengzhou.

The guards of the three cities of Ganzhou, Quanzhou, and Shazhou, as well as the general soldiers of Longyou Dao and Guannei Dao, had already received orders from the imperial court, so when Ge Dahai and the three arrived with military orders, the handover was very quick without any delay.

"Each person carries three days of dry food, and sets off together with baggage and grain......"

When the assembly was completed, Cheng Yanjin began to arrange with his rich experience in leading troops, and he couldn't live in peace for a moment.

On the other hand, Li Yan was much more relaxed, and after the horses from all sides were transported to Fengzhou, he personally led the cavalry battalion for final training.

Compared with the war horses of others, Li Yan's own war horses are much taller, which he extracted from "My World", which is an accelerated version of the potion.

Judging by the distribution of the muscles of its limbs, it is obvious that this war horse is extraordinary.

According to Li Yan's test, the horse's maximum speed is close to 140 per hour, and its endurance is even more against the sky, and there is no problem in running at full speed for an hour or two, and if the speed is slowed down for a few miles, it will not be breathless.

Such a divine horse, there was absolutely no mount comparable to it at the time.

Of course, the corresponding thing is that this horse extracted it to reality, and it cost Li Yan a full 8,000 experience points!

This is half a month's output of the monster farming tower......

(The monster farm tower is only useful if Li Yan is next to it, so you can't build more than one, and the monster farming range is limited, you can't build multiple layers, there will be other ways to get experience later, and it's currently about 500 experience per day)

After the last few days of training, Li Yan can already ensure a certain tacit understanding with the cavalry team, although it can't reach the level of the elite battalion's group of muscle bumps, but it is enough for Li Yan to complete this journey that spans nearly 5,000 miles from north to south alone!

……

In the early morning of this day, Li Yan personally led his troops to the gate of the temporary camp outside the city.

At this moment, 1,200 cavalry were ready, and Cheng Yanjin was leading the generals who came here from all over the country to support the cavalry vanguard led by Li Yan.

Of course, in addition to the cavalry of 1,200 men, the army of 30,000 was also ready, and the trek would begin in two hours.

"General Cheng, I'll leave it to you later."

Li Yan was wearing a battle armor, and a white robe was hung after the battle armor, so that his own people could determine their position on the battlefield.

"Don't worry, just Mo Nan, you can't stop the army."

Cheng Yanjin's words only mentioned Mo Nan, and he was obviously still a little worried about Li Yan's decision to go to Mo Bei.

"Go!"

Li Yan didn't care about Cheng Yanjin's reaction, he turned his horse's head, carried his Fang Tian painting halberd, and set off with a thousand-person cavalry team.

In this battle, although Li Yan was the nominal marshal, he was more responsible for the direction of the vanguard army.

To really coordinate the burden of the army, Li Yan chose to hand it over to the professional Cheng Yanjin.

At this point, 1,200 cavalrymen, under the command of Li Yan, set off towards the endless grassland without hesitation.

Their goal is very clear, all the way north, through the Gobi, straight to the Turkic king's tent!

"Congratulations to the marshal!"

At the gate of the barracks, the generals in the array, the nearly 10,000 soldiers behind them and those who were ready, and even the 20,000 soldiers who were still in the camp shouted in unison.

After half a year, from the Turkic army of 100,000 to the 1,200 cavalry of Li Yan to the grassland, as long as he is a Tang person, he will not be moved when he sees this scene.

I think that at the beginning, when the Turks entered the Guannei, they burned, killed, plundered, and forced the Tang Dynasty to set the Weishui Alliance, and all the Tang people remembered this blood feud and this national shame!

Today, the generalissimo of the Northern Expedition personally led the vanguard army into the steppe, which is to take revenge on the Turks on behalf of all the Tang people.

After all the soldiers knew the battle situation in winter, none of them regarded Li Yan as a god general at that time, and their hearts were full of joy and reverence.

What's more, now Li Yan only led a thousand people to dare to take the lead and enter the grassland first.

Therefore, all the soldiers shouted with unparalleled respect and worship in their hearts.

It is said that after the end of Li Yan's Northern Expedition to the Turks, there were folk songs and ballads:

"Fengzhou is out of the disaster year, and the city is like an iron wall in winter. In the spring, the battle of 6,000 miles will be carried out, and a thousand horsemen will be able to break the barbarians. ”
